Dispatching and automation of engineering systems. System of dispatching and monitoring of engineering systems Examples of automation of household and industrial systems

Automation and dispatching systems - a unified control system for a separate building, a complex of buildings or a separate section within an industrial, economic, public or residential facility.

Why are dispatching systems attractive for business? First of all - the ability to significantly reduce staff costs. In the conditions of modern management, replacing a person with a robot is the only right solution to optimize production costs and operating costs. In addition, the automation of engineering systems eliminates the intervention of the human factor and the problems resulting from it, which, as you know, occur in enterprises with a large share of manual labor with enviable persistence.

back side progress - the release of a significant number of workers previously employed in the provision of engineering systems, which does not always mean a significant reduction in the company's staff. Qualified employees can always be directed to other areas of production expanding by optimizing the management of engineering systems.

Modernization of management of engineering systems of the facility has other advantages. Automation responds to changing conditions much more quickly. Thus, due to more precise control of the processes occurring in engineering systems, significant fuel and electricity savings are achieved, as well as a decrease in equipment wear and tear, accidents, and, consequently, the need for frequent repair and replacement of components and mechanisms included in the engineering system.

Tasks and principle of operation of dispatching systems

The principle of operation of engineering systems management systems is to provide all units of the system with control controllers. The controllers collect information about the operation of the units, and also ensure that the data is received by the central post at a specified frequency. Each controller installed in a certain area is programmed individually, taking into account all the requirements and features of the operation of this unit. Collected together, the data coming from the controllers are systematized in the central office and, using special software, are compiled into a single whole - a graphical report on the system operation in real time.

However, the role of controllers is not limited to collecting data on the operation of the system. The main task of dispatching systems is to manage the engineering systems of the facility.

The dispatching system manages the refrigeration supply, systems counter fire alarm, controls and manages air conditioning, ventilation and heating systems, as well as regulates the lighting of the premises. In addition, the dispatching system is responsible for the timely operation of smoke ventilation in the premises.

The system collects, organizes and catalogs information coming from controllers. In case of detection of deviations from the specified parameters, the system sends a signal to the controller, which corrects the operation of this module to achieve the standard parameters.

In addition, the system analyzes the overall energy costs and adjusts the operation of all modules to achieve significant energy savings.

Operational information about the state of the system as a whole and individual modules is displayed on the display in the control room in an easy-to-read graphical form tables and diagrams. This principle of presenting information allows you to assess the operational situation at a glance, and, if necessary, correct the operation of the system from the control panel.

System software

Engineering systems dispatching equipment is supplied complete with specialized software. This software collects and processes information, automates the processes of its processing, graphical output to the display, and also manages all modules of the facility's engineering system.

Processor microcontrollers are programmed directly during system design for each specific module. Each controller is connected to parameter sensors for collecting information, module power cabinets for control, and a central dispatching console for adjusting module control within the system as a whole.

The controllers on each module operate autonomously, but are adjusted by the system as needed.

The software is installed on the main server in the central control room. The system diagram is shown on the display. Changes in the operation of the system are displayed and duplicated by sound signals.

Dispatch system is designed to remotely display the collection and storage of data on the operation of the technological equipment of a building or a production process, it transmits information about the parameters of ongoing processes, operating modes of engineering systems, and emergency situations. The interface of the dispatching system allows the operator to remotely set the operating modes of the system as a whole or individual equipment.

The requirement for the presence of dispatching systems in modern buildings is determined by SP 31-110-2003 "Design and installation of electrical installations of residential and public buildings". VSN 60-89 “Communication, signaling and dispatching devices for engineering equipment of residential and public buildings. Design standards” - regulates the design of dispatching systems.

Thus, the main purpose of the dispatching system is to centralize the control and management of the building.

There is sometimes confusion when a building management system is defined as a building management system BMS. This is due to the fact that controllers and SCADA software of BMS systems will be used in dispatching. However, the dispatching system is an interface part of the smart building system, it only outputs information to the control panel and allows the operator to manually control part of the processes, albeit remotely. Algorithms for optimal and economical interaction between building subsystems must be developed by the automation project and programmed in the control controllers, only then the operator is freed from making most of the routine decisions.

The dispatching system is not a complete automation system! It performs functions related to the display - "supervisory control" and manual remote control- "dispatch control" of engineering systems.

Typically, the functions of the dispatching system include:

Data collection from devices and visual display of processes occurring with the engineering equipment of the building (for modern systems, using SCADA);
Timely detection of emergency situations, prevention of accidents;
Formation and sending of alarm messages to responsible persons;
Remote control of engineering systems devices;
Collection and storage of instrument readings in automatic or manual mode;
Presentation of data in graphical and tabular form;
Maintaining reports on energy consumption, generating reports automatically and at the request of the operator;
If necessary, transfer data to a higher priority remote control.

Information flow from the following systems is displayed on the dispatcher console:

Supply and exhaust ventilation;
Air conditioning and refrigeration;
heating;
Heat supply (ITP or boiler equipment);
Water supply, water treatment, sewerage;
Lift and escalator equipment;
Power supply and electric lighting;
Fire alarm and building security systems;
Sound control systems;
Fire-fighting automation (smoke ventilation and fire extinguishing);
Other systems related to production or process control.

Outside air temperature, chilled water to/from the ventilation system, chilled ethylene glycol, heated heating water can be displayed; pressure values of chilled water or ethylene glycol of ventilation and air conditioning systems; control valve positions; power on the motors of circulation pumps or fans; ; filter clogging data; alarm about the threat of freezing heaters information about the state of elevators, supported by video data; state of circuit breakers in electrical panels, etc.

The control of equipment in dispatching is limited by the ability to enable certain operating modes, for example, the system start mode in winter or summer, maximum performance mode, emergency shutdown of the unit, manual switching from the main to the standby pump, etc. In theory, the dispatcher has the ability to control each of the devices with a drive, but in practice, one person physiologically will not be able to manually control a large engineering system.

The management of such a system is carried out 24/7 by qualified personnel who have completed specialized training courses. In addition, for each system in the process of design, commissioning and operation, technologists develop action protocols for possible emergency situations.

Possibilities of modern dispatching systems

Modern systems dispatching more and more implemented on controllers and software of BMS systems. This causes a large number software features to set up their functions. In general, dispatch systems should provide:

An up-to-date and complete picture of the state of all engineering systems at any time;
Convenient and clear graphical interface;
Quick response to emergencies;
Possibility of issuing emergency messages on the monitor screen, printer, remote computer, mobile phone;
Registration of all system events, which in many cases makes it possible to establish the cause emergency, its culprit, as well as prevent its occurrence in the future;
Connecting to the system remotely via an Internet browser;
Quick and adequate response to changing environmental conditions;
Automatic counting of engine hours, equipment time to failure and warning about the need for maintenance and preventive maintenance;
Ample opportunities for managing systems, which allows to reduce the staff of maintenance personnel;
Possibility of collecting statistical information, forming samples, graphs comparing cost forecasting.

The difference between a dispatching system and a building automatic control and dispatching system (SAUiD)

The main differences between the functions of the dispatching system for engineering equipment and the system automatic control building are visible in the diagrams below. Typical scheme dispatching of engineering systems of the facility

Typical scheme of automation and dispatching of engineering systems of an object (synonyms: BMS, intelligent building)

In this way, the dispatching subsystem is only part of the BMS building management system.

Equipment and software for dispatching systems

The task of dispatching is to display information and provide control, therefore, the main elements of the dispatching system are operator software and interface converters, often installed in automation panels of engineering equipment.

As a rule, modern automation controllers have the ability to work with SCADA software of the dispatching system, they are also interface converters. Software provides the implementation of such functions as:

Displaying information in the form of mnemonic diagrams with the issuance of real-time measurement values, controller settings, various icons and other graphic objects;
Formation and issuance of emergency messages;
Maintaining archives (trends) for all hardware signals and calculated technological variables;
The possibility of correcting the operation of the system, without stopping it;
Possibility to search and filter records of archives by a number of selection criteria; the ability to generate reports based on user-defined templates; viewing archived information in the form of graphs and tables;
Ability to create schedules, multi-level access and other functions of computer control systems.

Data transfer from the local automation system to the SCADA dispatch system can be carried out directly or through the interface of the OPC (Open Platform Communication) server. Wherein OPC server is a translator between the language that the installed equipment understands and the language of the dispatcher's software interface.

The main goal of the OPC standard was to ensure the possibility of joint operation of automation tools operating on different hardware platforms in different industrial networks and produced by different companies.

After the OPC standard was put into effect, almost all SCADA packages were redesigned as OPC clients, and each hardware manufacturer began to supply their controllers, I / O modules, smart sensors and executive devices by a standard OPC server. Thanks to the advent of interface standardization, it became possible to connect any physical device to any SCADA, as long as they both complied with the OPC standard. Developers got the opportunity to design only one driver for all SCADA packages, and users got the opportunity to choose hardware and software without the previous restrictions on their compatibility.

IP equipment

90% of modern dispatching systems have the ability to exchange information over IP networks. The conversion of data into the appropriate protocols takes place either directly in the controllers, or on top-level servers (Schneider Electric Automation Server), or through gateways, for example, Xenta-911.

With cheaper IP equipment, the functions of data transmission to the network are gradually being extended to field devices (valves, frequency converters, etc.), but this solution is still more expensive in any case, and also requires the development of a stable and secure SCS at the facility, this is true is an expensive undertaking.

IP equipment for automation and dispatching engineering systems is selected depending on the requirements for its functions. As a rule, it is enough to have a software interface between the dispatching system and the enterprise IP network, and it becomes possible to connect additional information to the SCADA system. In particular, for visual monitoring of important nodes or premises from the control room, IP surveillance cameras of the industrial television or security system are connected to the system.

Development and design of dispatching systems

The project of the dispatching system is carried out by section of the set of drawings of the building automation and dispatching system. The signals output to the dispatcher's console are determined by the developers of the building systems technology.

Design standard: VSN 60-89 “Communication, signaling and dispatching devices for engineering equipment of residential and public buildings. Design standards"

A dispatch system design will typically contain the following sheets:

As part of the dispatching project, an automated workplace dispatcher. Depending on the scale of the system, it can be equipped with:

Shield with applied mnemonic diagram(at present, such systems are less and less common in production);

PC with installed SCADA software;

PC with web interface access to the controller-server of the system (example: automation server Schneider Electric);

PC with installed SCADA system with access to multiple monitors and monitor wall.

Automation and dispatching of engineering systems

Once building and literally forgetting about the existence of engineering systems allows automation and dispatching. Without automation, any of the subsystems would carry more problems than comfort, since it would require constant and careful attention to its work.

Has the correct temperature been reached? Will the water freeze in the heater? Is the tank full? Will the air heater burn out? Is there a water flow? Is the pressure normal? Is there tension? What sensor worked? And it's far from complete list questions answered by the automation and dispatching system.

The complexity and cost of such systems depends on the level of their intelligence and the number of functions performed. However, any automation system must perform basic functions, which, for example, ventilation and air conditioning systems, are the following:

Control and management of the operation of units that are part of the equipment of ventilation and air conditioning systems,
- control valves and dampers,
- Safety assurance: blocking the heater in the absence of air movement, frost protection of the water heater,
- Protection of equipment from overheating, short circuit, incorrect connection,
- Indication of the state of the operating equipment,
- Performance regulation,
- Centralized control temperature regime in all rooms,
- Implementation of a temporary control algorithm (daily/seasonal/annual) without the intervention of maintenance personnel.

In addition, automation is mandatory for heating systems, is very popular in electric lighting systems, and can also be introduced into the power supply system, security, etc.

Automation and dispatching are numbers 1 and 2 in the list of design principles and arrangements of modern engineering systems. On the one hand, technology strives to ensure that networks work with minimal human involvement - as they say, build, run and forget. On the other hand, the customer sets the task of ensuring the most reliable control of the processes occurring in the network throughout its entire length.

In the event of a change in system parameters and various emergency situations, a signal about this should immediately go to the control center, where automation or a human operator will make an operational decision. So, when the pressure drops in the water supply, the automation should immediately turn off the emergency section. If there is a threat of melting the heating element, turn off the incoming voltage or reduce the current.

In addition, commands should be sent as quickly as possible from the control center to change the parameters of individual sections of networks or the entire network in case of changes in external conditions. For example, when the air temperature in a heated house decreases, the power of the boiler automatically increases. If the input voltage drops in the external electrical network, stabilizers come into operation, sources uninterruptible power supply, and if necessary - an autonomous generator or other backup line.

Automated management of building engineering systems is carried out on the basis of industrial controllers. The main advantage of controllers is their functionality and uniformity, that is, the same controller can control any engineering system.
Depending on the connection of the required sensors to any engineering system, the engineer selects a controller that is suitable for the number of digital and analog inputs and outputs.

After completing all the work on the selection of controllers, sensors, other necessary elements, laying communication lines, the programmer proceeds to visualize and program processes directly on the computer. Programming and visualization of processes are carried out in the so-called SCADA system, which is represented by various computer programs depending on the manufacturer of the hardware and data interface.

Examples of automation of domestic and industrial systems

The ECOLIFE group of companies has significant experience in designing, installing, commissioning and maintaining engineering systems of any complexity, length and localization. We work with a wide variety of environments:

Water (automation of water supply, heat supply and heating systems);
- air and gas-air mixtures (automation of ventilation and air conditioning systems);
- various industrial fluids and liquid fuels;
- intangible objects - electricity, light, radio waves.

Our engineers and installers perform professional installation and adjustment of auxiliary automated systems - fire extinguishing, security and fire alarms, remote access control, internal and facade lighting.

In all cases, the emphasis is on the maximum autonomy of the systems. For automatic lighting control timers are used that are configured taking into account the calendar duration of day and night, photocells that record the natural illumination of a room or area, motion sensors that are configured to move objects of a given mass and dimensions.

The control of the perimeter or internal volume is carried out by electromagnetic sensors that record the crossing of a conditional border or movement within it.

A fire signal is given by devices that analyze the state of the atmosphere and temperature environment. The smoke analyzer, having caught particles or molecules of combustion products in the surrounding space, simultaneously sends a signal to the central control room and activates local means of fighting fire. Automation reacts in the same way in the case sharp increase temperature of air or surrounding objects.

As we have already indicated above, automation is needed not only for emergency response in the event of a fire, flood, or intruders entering the facility, but also for resolving quite normal situations associated with a change in the degree of load on the network. For example, in the conditions industrial production working in one or two shifts automation of power supply systems will allow, without human intervention, to increase the power supply of the facility every morning, and to reduce it every evening. Our specialists will quickly and professionally install the necessary equipment that will help optimize energy consumption and reduce current payments to resource supply organizations.

Building and network management systems

The larger the object on which automated engineering systems are mounted, the more important is the role of their dispatching - that is, remote control and management of engineering systems and notification of all processes occurring in the system. AT big building or a structure where pipes, air ducts, power cables and SCS have a length of tens and hundreds of kilometers, and the availability of many nodes and sections for technical and design reasons is very difficult, the availability of a workable end-to-end monitoring system comes to the fore.

Dispatching concerns two main parameters - the state of the environments moving through the engineering systems and the state of the engineering systems themselves.

Temperature, pressure, density, viscosity, direction and speed sensors, and chemical analyzers are used to measure the parameters of the network content. System state sensors react to the appearance of cracks, ruptures, corrosion, mechanical damage stop valves and connecting elements, blockages, deposition of salts or oxides on the walls of pipes and other negative changes that can affect efficient work engineering structure and jeopardize the safety of the facility. In the case of power supply systems, the measuring equipment records the current voltage and current strength, an abnormal increase in resistance in certain sections of the network, which leads to an increase in power consumption and overheating of cables, which in turn can cause short circuit or fire. If we are talking about production with several sections that consume a large amount of industrial current, then competent system dispatching will allow rational distribution of loads, thus saving electricity and preventing excessive load on one line compared to others.

Automation of ventilation and air conditioning systems

Ventilation in modern buildings is represented by a system supply and exhaust ventilation with heat recovery in winter. This system provides for the installation of a number of sensors: a temperature sensor of the incoming outdoor air, a temperature sensor of the air leaving the atmosphere, a temperature sensor of the air heater discharge pipe, a temperature sensor of the outgoing air stream from the building, a room temperature sensor, a pressure and air velocity sensor in the air duct. It is also necessary to control the mode of operation of the supply (supply) and exhaust fans, the state of the heat exchanger, clogging of air duct filters and other parameters. For control and operational regulation of all these parameters of the system, automated control systems based on industrial controllers are used.

In buildings commercial purpose(shopping, entertainment centers, restaurants, airports, etc.) there is a need for centralized management split systems or a set of systems with a chiller-fan coil. Management can be carried out on the basis of an industrial controller with a supervisory control system.

dispatching and automation of ventilation and air conditioning systems in a large office center, it will also save the cost of operating systems by taking into account such factors as temperature and humidity in the room and outside the window, the number of people working in the premises, and the insolation of the building. Modern automatic program climate control can save up to 50% of electricity compared to a typical situation when all air conditioners in a building turn on at full capacity in summer. In addition to financial benefits, optimization in terms of climate will help to avoid personnel losses - after all, it is well known that the uncontrolled operation of air conditioners and climate systems is the main cause of colds in the summer.

Our engineers will perform necessary calculations ventilation and air conditioning systems, will carry out the installation of automation equipment and, together with the company's programmers, will set up the system in the shortest possible time.

Automation of alarm systems

Competent alarm system dispatching- a guarantee of the safety of any object. Professionals of the ECOLIFE group of companies are ready to perform work on the complex installation of security systems of any level of complexity. We work with perimeter alarms, interior space security open areas and enclosed spaces, protection of specific objects intended for the storage of inventory items or playing another important role (safes, vaults, storerooms, archives, armory rooms, command and communication centers, etc.).

Reliable scheduling at the device is most important perimeter systems protection, which can have a length of tens of kilometers. More than ten types of alarms have been invented in the world, but they all operate according to the same principle: as a result of an attempt to penetrate the perimeter (or even when approaching a conditional line), a certain electrical circuit, as a result of which an alarm signal is sent to the control room. In modern security systems, penetration can also cause other forms of reaction - the inclusion of emergency lighting, video recording and photo recording systems, warning sirens, blocking exits, etc. Turning to the specialists of the ECOLIFE Group for help, you can make your facility practically invulnerable to all forms of ill-wishers and intruders.

Automation of heating and heat supply systems. Boiler room dispatching

Our interests extend not only to large industrial facilities that provide large volumes of design, installation, commissioning and service work. With the same responsibility, we are ready to perform automation and dispatching of engineering systems at low-rise construction sites.

Many owners of cottages and dachas strive to equip their homes with the latest technology, without initially thinking about the cost of operating systems. Meanwhile, our experience shows that the correct placement and configuration of networks will make their operation not only convenient, but also cost-effective.

In a small country house it concerns first of all boiler house dispatching and heating point , which will allow you to efficiently spend natural gas or other fuel and maintain an optimal energy balance at home with an autonomous heating system.

Ecolife Group specializes in the automation of all types of heating of residential buildings and other premises.
Temperature sensors are used to automate the process of space heating. At the request of the client, a choice of temperature control method is made, taking into account the optimality criterion. To set the necessary parameters of the system operation, control panels are used, which, together with sensors and servo drives, are connected to the controller.

Optimization of heat in residential buildings has been a trend in developed countries for a decade and a half. Gradually, he begins to gain popularity in Russia, although our climatic conditions is objectively more difficult than in Europe, where the philosophy of internal energy efficiency was originally born. It is curious that in English such a house is called a passive house.

In Russia, with its sharply continental climate, it is hardly possible to do without heating and build a completely “passive house”. But by setting up a competent accounting of heat consumption, using effective insulating materials and controlled heating systems, it is possible to minimize fuel consumption, and hence material costs and environmental damage.

Boiler room dispatching with the help of specialists of the ECOLIFE Group of Companies - the most important part of the device for autonomous heat supply at home. Often, boilers are installed directly in basements and plinths, however, from the point of view of fire safety and ecologists are better off doing this in a separate building. Heat loss during supply hot water from the boiler room to the house with the installation of high-quality insulation are insignificant.

Having adjusted remote control during the work of the boiler house, the owner of the house can directly control the fuel consumption, steam pressure in the heat exchanger, the temperature of the water in the circuits, the percentage of combustion of the mixture and other parameters directly from the office. Information comes both from a variety of sensors and visually, using video cameras. Broadcasting of telemetry information can go by wire and wireless communication channels (bluetooth, Wi-Fi, radio). Dispatching can also be organized at remote sites, controlling, for example, the operation of a boiler room country house from a city apartment, office or just from a mobile phone, being on the other end the globe. Modern mobile and Information Technology provide unlimited possibilities by organization as control room at the facility, and a virtual control room on the World Wide Web.

For more than 20 years, CROC has been involved in the automation and dispatching of building engineering systems. The accumulated experience allows us to implement automated systems of any level both in office and industrial buildings, and in shopping malls, data centers and sports facilities.

Local automation

No matter how reliable and intelligent the system is, any engineering solutions need local automation, because it is it that ensures the independent operation of the equipment and its protection if necessary. This is a kind of "hand brake" that prevents breakdowns in emergency situations and allows specialists to adjust the operation of the equipment in manual mode. For local management of engineering systems, CROC specialists can offer both ready-made control cabinets and solutions assembled individually for the project, which can be integrated into common system dispatching.

"Smart Office"

Room or office automation is a solution that allows you to maintain the temperature, air exchange, lighting and microclimate in general at the proper level, while maintaining a balance of energy efficiency. The controllers underlying such systems compare data from various sensors and, based on this, implement automatic scenarios embedded in them. Depending on the composition of the systems, such scenarios can control both the switching on of lamps in the presence of a person, and the change in the volume of air supplied to the room depending on the level of CO2. In conjunction with the dispatching system, room automation can be controlled centrally and remotely, but users themselves can always set the desired parameters manually.

Building management systems

Automated systems operational dispatch control (ASODS) are indispensable for large facilities, where it is important to have accurate data on the state of each component of the engineering infrastructure. Their goal is to read data from each local automation device and provide it to the specialists of the facility operation service in an informative and visual form.

ASODU includes a data transmission network, computing resources, a set of information display tools, interface converters, specialized software, as well as protocols through which information is exchanged between controllers, actuators and sensors. As a result, the operator receives a complete picture of the state of the engineering systems on the screen of the control panel.

Energy management system

At large facilities, the issue of resource consumption is always quite acute, since it is directly related to the volume of operating costs. The introduction of energy management systems (EMS) solves the issue of collecting and presenting information in a visual form from all gas, water, electricity and heat meters installed at the facility. This significantly simplifies settlements with tenants and allows timely optimization of resource consumption.

Data Center Infrastructure Management System

It is no secret that in data centers it is important to maintain certain parameters temperature and humidity. But it is also extremely important how much electricity is spent on the entire data center system and its individual elements, because based on this data, it turns out what the current energy efficiency ratio is.

In addition to the issues of ensuring the conditions for the correct operation of server hardware, questions often arise related to the racks themselves: for example, where are the free computing resources and what should be done to scale the infrastructure in the future? Data Center Infrastructure Management systems make it possible to virtualize information about all physical and information assets of data centers, and CROC specialists have vast experience in designing and implementing them.

Monitoring systems for engineering systems and structures

There are facilities that need special control not only from the facility operation service, but also from the unified duty and dispatch service of the city or district. These can be nuclear and hydroelectric power plants, stadiums, large hotels, concert venues and other crowded facilities. It is for such places that SMIS / SMIK are intended. These systems collect and transmit data on the state of the engineering infrastructure and the load on the structures to the EDDS, so in the event of a threat of an emergency or a terrorist attack, measures will be taken immediately.

Operational process management system

The operation process management system (Computer-aided facility management (CAFM) is the management of material resources and processes inside buildings and structures that are not related to the main activity at these facilities. The system automates the main information processes in the operation of the operation service, which reduces the consumption of energy resources and reduce the cost of maintaining the building, optimize the use of equipment, effectively manage the personnel of operational services, and promptly prevent emergency and emergency situations.

AT modern building dozens of different engineering systems and automation and dispatching systems are designed to ensure the efficiency of these systems. The use of automation and dispatching in the infrastructure of the building allows you to control the state of individual systems, record the parameters of their work, reduce energy and heat costs, equipment wear and tear, and respond in a timely manner to emergency situations.

The automation and dispatching system is traditionally divided into 3 levels:

Periphery equipment;
Field controllers;
top level system.

Periphery equipment these are various types of sensors (water pressure, water temperature, air temperature, etc.), shut-off and control equipment, actuators, valves.

Controllers it is the central part of automation and dispatching systems. Structurally, they can have a distributed structure of I / O modules, or they can be represented by a single block. The controllers are usually installed either in a control cabinet or in a combination cabinet including both electrical part as well as automation.

In the latter case, special measures must be taken to protect them from interference. Combining power cabinets and automation cabinets allows you to reduce cable runs and reduce the total cost of installation. For data exchange between controllers, networks with their own data transfer protocols are used: Lonworks, BACnet, ModBus, EIB, KNX, C-Bus and others. Data transfer protocols can be either open or closed, used by only one controller manufacturer. The advantages of open protocols over closed ones is that the customer is not tied to a specific equipment manufacturer and can use controllers from various companies that use this open protocol.

Lonworks is the most common solution among open systems. There are millions of Lonworks-compatible devices in the world installed in offices, homes, factories, and transport. Lonworks devices are capable of transmitting information over twisted pair, Ethernet networks, optical fiber, infrared and radio channels. The Lonworks communication protocol is the same for all devices, which ensures the compatibility of various equipment: freely programmable controllers, temperature control panels, valves, presence detectors, air conditioners, chillers, heat and electricity meters.

Top-level systems allow maintenance personnel and users to track the state of the system, quickly respond to emergency and pre-emergency situations, save process parameters and record operator actions for further analysis. Modern top-level systems make it possible to:

Creation of graphic screens, mnemonic diagrams, menu systems and windows for displaying technological information;
Archiving of data transferred technological equipment or formed during processing;
Archiving of events, APS signals, as well as reporting;
Protection against unauthorized access;
Registration of system launches and other operator actions (system logging);
Use of a powerful statistical processing subsystem;
The presence of a real-time database located in RAM, where all system and user-defined variables associated with technological data and objects displayed on the screens are located.
Build a distributed hierarchical system in which the server collects and stores information, and workstations allow operators to interact with process equipment independently of each other.
