Heating network buildings, power supply networks, ventilation and air conditioning require special equipment for automatic control of work. Residential building systems also need to account for consumed resources and carefully monitor the operation of all engineering systems. Our company produces automation of engineering systems in Moscow, with the help of which automatic control and dispatching is carried out.

Ensuring engineering infrastructure dispatching

The engineering systems dispatching system is a way to control the distribution and accounting for the consumption of various resources used during the operation of a building. If the dispatching system is installed in production, then it also performs the functions of monitoring and controlling all parameters of production activities. The engineering systems dispatching system is introduced into the automation system and allows you to control all parameters of the infrastructure of a building or production. Our company produces high-quality and reliable equipment for the automation of engineering systems.

With the help of automation and a dispatching system for engineering systems, significant savings in energy, water and other resources can be achieved. Such a system will help to control the level of safety and reduce the risk of an accident at the facility.

On the basis of OWEN equipment, a set of works was carried out to automate and dispatch engineering systems of the building of the Administrative and Business Center of the Troitsky and Novomoskovsk administrative districts of Moscow.

The project provided for the automation and dispatching of the following engineering systems:

1. Ventilation systems

2. Thermal curtains

3. Refrigeration system

4. Drainage pumps

5. Gas control

6. Pumping station drinking water pumps

7. ITP (individual heating point)

The principle of building control systems and structure

ARIES equipment was used to automate the engineering equipment of buildings. The system is made on a two-level principle. At the local level of automation, freely programmable communicative controllers OWEN PLC154 are used, located in control and automation panels. To expand the discrete and analog inputs/outputs, the OVEN MB110, MU110 input/output modules are used, which are connected to the controller via the RS-485 (Modbus RTU) interface. Communication between the controllers, as well as with the control room, is carried out by means of data transfer via the Modbus TCP protocol based on Ethernet technology.

To control the engineering systems of the building, control panels have been developed that are located close to the controlled units. In addition to automation, the boards house ballasts, switching and lighting equipment, relay automation elements, secondary power supplies and controllers.

At the basic level of automation (the level of controllers), direct (without the participation of the dispatch system computer) continuous control is provided technological equipment, automatic maintenance of set parameter values technological systems.

At the top level, interaction is carried out between the personnel (operators, dispatchers, etc.) and the system through a human-machine interface, which is a specialized server and a SCADA system.

To view and change the control parameters, it is possible to connect a control panel that provides convenient access to the controller parameters in the form of a system of Russian-language menus. The project provides for power supply, protection and control of equipment in both automatic and manual control modes.

The main functionality of top-level control systems:

• control of the main parameters of life support, the state of equipment and subsystems of information and engineering support from the central control room of the facility;
• visualization of information about the state of equipment, parameters, facilities and life support subsystems;
• operational indication, registration, signaling of deviations in equipment operation from permissible values;
• archiving, documentation and printing of the necessary information;
• damage alarm analysis;
• logging of equipment operation and personnel actions;
• automatic call for service personnel in case of emergency situations.

Automation of engineering systems of buildings pursues an important goal - automatic control of all communications existing at the facility. The alternative, which involves manual control, is hopelessly outdated - it is necessary to conclude contracts with personnel, constant monitoring of all parameters and indicators, the risk of the human factor increases many times, and one mistake can lead to serious consequences, including accidents.
Did you manage to achieve optimal temperature indicators? Is the system at normal pressure? Does the voltage meet the declared parameters? Are there sufficient volumes of coolant in the working circuit? This is far from full list questions to be answered by the automated system.
The exact set of complex functions depends on its type and configuration. The specialists of our company are ready to design and install systems of any complexity. Most simple options perform the following tasks:

• Management of the functioning of modules that make up heating, ventilation and air conditioning systems, reading their performance indicators, checking for compliance with standard values;
• Actuation of dampers and valves, if the need arises;
• Security guarantee. For example, if the system detects the immobility of air masses, the heating elements are turned off. If the water heating begins to freeze, the temperature of the coolant automatically rises, which eliminates the formation of ice in the circuit, which can provoke breaks and difficult restoration work;
• Protection of working modules from activities under increased load, errors in the connection process, short circuits, excessive heating;
• Assessment of the state of working modules;
• Adjustment of performance in accordance with current needs, which provides the most comfortable conditions at the facility, and also eliminates the overspending of energy resources;
• Continuous monitoring of temperature conditions in each of the controlled premises;
• Changing performance indicators in accordance with given algorithms without the need for human intervention.

Dispatching engineering systems of a building, a group of buildings, an enterprise is one of the most urgent problems in the implementation of automated process control systems - process control systems. Modern engineering systems are complex, complex systems, for the normal functioning of which automated dispatching systems are required. Engineering equipment included in the life support complex of buildings, as a rule, has a huge set of technological parameters and signals that require continuous monitoring. Such control can only be achieved modern systems dispatching.

Dispatching of engineering systems allows you to expand the traditional automation of engineering systems and bring it to a level at which monitoring and control of all systems is carried out from one dispatcher workplace. Dispatching engineering systems allows you to maintain their performance and improve the efficiency of energy use. Thanks to the operational control of the state of engineering systems and timely response to changes in the operation of systems and equipment, it is possible to effectively make management decisions and prevent possible failures.

The essence of dispatching is to visualize information about the functioning of engineering systems and provide the operator with the ability to directly control the equipment from the control room. Data on the state of engineering equipment is received from local automation controllers and transmitted to the server. The processed technological data with the necessary analytical information is sent to the dispatching server and displayed on the computer screens at the operators' workplaces in a visual dynamic graphical form.

When using dispatching systems of engineering systems, the rationality of using all types of resources increases and thereby increases the profit from the operation of facilities. The automated dispatching system for engineering systems allows you to take into account energy resources, normalize their consumption, adjust equipment operation taking into account external conditions. Thus, the client can save a significant share of financial resources and direct them to business development.

• Issue context prompts to the dispatcher in emergency situations;
• Keep a log of events in automatic mode, documenting the causes of accidents, losses and their perpetrators;
• Obtaining and analyzing data for the development of measures aimed at improving energy efficiency.

Dispatching covers engineering systems:

• Lighting indoor and outdoor;
• Boiler plants and individual heat points forming a heat supply system;
• Elements exhaust ventilation(VV) and supply ventilation (PV), central air conditioners and closer air conditioners (fan coil units, thermal curtains, air flow regulators);
• Refrigeration centers and refrigeration stations;
• Security and fire alarms (smoke exhaust devices, fire dampers, water and gas fire extinguishing etc.);
• Separate wells and water intake units, pressure boosting units;
• Cold water supply (HVS);
• Hot water supply (DHW);
• Leak control (flooding and drainage);
• Diesel power plants, transformer substations, high-power UPS, power distribution devices;
• Energy resource metering units;
• Elevators and escalators;
• Access control and management systems, video surveillance.

The engineering systems dispatching system is a multi-level remote control and management system. It consists of:

Lower level (field level): sensors, actuators and cable system. The lower level can include from units to thousands of signal sources, interrogated sensors, various devices connected via different types interfaces that transmit information to mid-range equipment.

Middle level: controllers that receive and process analog, discrete signals and generate control commands. Medium-level equipment is programmable controllers, modules of discrete, analog inputs, relay inputs and outputs. The controllers convert the data received from the monitored equipment, make preliminary calculations of the equipment state, generate data packets, and also generate signals for the controlled devices. An object can contain hundreds of these controllers, depending on the structure and size of the object.

Upper level: control computer with application software (operator workstation). The top-level hardware is a computer with special software. It requests and receives data from controllers.

The software that the operator works with displays the equipment involved in the system in a form convenient for the operator (building layouts indicating the location of equipment, structural chains of equipment for various subsystems). It is possible to work with logs of alarms, events, actions of operators, filtering events in logs by date, time, type of event, type of equipment. The operator's workstation can set the parameters of the equipment operation, with the appearance of alarms when the parameters go beyond the specified limits, display the statistics of changes in the parameters of the systems in the form of graphs and tables. The rights of users are also differentiated by the possibilities of management, dispatching of engineering systems.

Dispatch post (operator workstation) equipped with a source uninterruptible power supply, sound alarm and incorporates 3 monitors (left, center and right). From the point of view of placing information on them, each monitor is independent and self-sufficient. Each monitor can display any frame with information. The distribution of frames with information on monitors is made by the dispatcher himself, based on his own preferences and ease of perception.

There are the following frame types:

• start frame;
• Main mnemonic scheme of buildings;
• Main mnemonic scheme of the structure;
• Mnemonic circuit of the engineering system;
• Mnemonic diagram of the floor plan for the placement of equipment.

For quick troubleshooting, a display of a floor-by-floor mimic diagram of equipment placement is provided, on which it is possible to accurately determine the location of emergency equipment.

After the dispatching system is put into operation, the NTC Energo-Resource company provides service maintenance of the system. The company's specialists, in agreement with the customer, using remote access, can see the real picture of what is happening in any dispatching circuit of the customer's facility in the "on-line" mode and make the necessary changes to the software.

The need to use engineering systems dispatching systems is obvious. They enable reliable interaction between all subsystems of the object's life support, operational control and management. The more complex the engineering complex of an object, the more important the role of dispatching systems.
