Dispatching engineering systems buildings, groups of buildings, enterprises - the bottom of the most urgent problems in the implementation of automated control systems for technological processes - process control systems. Modern engineering systems are complex, complex systems, for the normal functioning of which automated dispatching systems are required. Engineering equipment, which is part of the life support complex of buildings, has, as a rule, a huge set of technological parameters and signals that require continuous monitoring. Only modern systems dispatching.
Dispatching of engineering systems makes it possible 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's workplace. Dispatching of engineering systems allows maintaining their operability and increasing the efficiency of energy resources 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 make effective management decisions and prevent possible failures.
The essence of dispatching is to visualize information about the functioning of engineering systems and to provide the operator with the possibility of direct control of equipment from the dispatching point. Status data engineering equipment come from the local automation controllers and are transmitted to the server. The processed technological data with the necessary analytical information is sent to the dispatch server and displayed on the computer screens at the operators' workplaces in a visual dynamic graphical form.
When using dispatching systems for 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, and adjust the operation of equipment taking into account external conditions. Thus, the client can save a significant share of financial resources and direct them to business development.
STC Energo-Resource effectively develops and implements automated dispatch control (ASDK) and control systems (ASDU) of engineering systems of various objects:
Implementation of the ASDK dispatch control system, and, if required, the ASDU dispatch control and management system allows:
Dispatching covers engineering systems:
The dispatching system of engineering systems is a multilevel remote monitoring and control system. It includes:
Lower level (field level): sensors, actuators and cable system. The lower level can include from units to thousands of signal sources interrogated by sensors, various devices connected by different types interfaces transmitting information to the equipment of the middle level.
Average level: controllers that receive and process analog, discrete signals and generate control commands. Middle-level equipment is programmable controllers, discrete, analog input, 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 controlled devices. An object can contain hundreds of such controllers, depending on the structure and size of the object.
Top level: control computer with application software(Operator's workstation). The top-level hardware is a computer with special software. It requests and receives data from controllers.
The software, with which the operator works, displays the equipment involved in the system in a convenient form for the operator (building layouts indicating the location of equipment, structural chains of equipment for various subsystems). It is possible to work with the logs of alarms, events, operator actions, filtering events in the 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 system parameters in the form of graphs and tables. The differentiation of user rights is also carried out according to the possibilities of management, dispatching of engineering systems.
Dispatch post (operator workstation) equipped with a source uninterruptible power supply, sound alarm and includes 3 monitors (left, center and right). From the point of view of placing information on them, each monitor is independent and self-sufficient. Any frame with information can be displayed on each monitor. The distribution of frames with information on monitors is carried out by the dispatcher himself, based on his own preferences and ease of perception.
There are the following types of frames:
To quickly eliminate the malfunction, a floor mnemonic diagram of the equipment placement is provided on the screen, on which it is possible to accurately determine the location of the emergency equipment.
After putting the dispatching system into operation, 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 object in the “on-line” mode and make the necessary changes to the software.
The need to use dispatching systems for engineering 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 the facility, the more important is the role of dispatching systems.

Any modern buildings (public, residential, administrative, industrial, etc.) are equipped with a large number of engineering structures that ensure the safety and comfort of people. The increase in the volume of construction of buildings with an increase in their number of storeys, saturation with complex equipment requires the widespread introduction of Automated Control Systems (ACS) in housing and communal services.
In modern buildings, the work of the following engineering systems is automated:
Automation of engineering equipment of buildings is necessary for constant monitoring of its work. Automatic systems they themselves observe, fix, record, the set of conditions of the building equipment. In accordance with the specified programs, the automation systems can react to changes in the readings of the sensors, and change the modes or parameters of the functioning of the engineering systems of the building. They notify personnel about critical and close to emergency conditions of engineering equipment. Allows dispatchers to make quick decisions in non-standard and emergency situations.
Building automation systems consist of numerous sensors, controllers, control subsystems, united under one common control system. This control system allows you to set programs for the functioning of both the entire engineering system of the building as a whole, and its parts, as well as monitor the controlled subsystems of the building from dispatch terminals, and carry out through them general control or programming of the operation of automation systems.
Automation of engineering systems of buildings can significantly reduce the operating costs of their maintenance due to constant automatic control, increasing the service life and productivity of engineering equipment and economical use of resources.
Automation of power supply timely reveals malfunctions in the operation of electrical equipment that can pose a threat to life for people, cause enormous damage to the economy or cause massive rejects of the company's products. This is especially true for buildings and structures with a large crowd of people, such as: subways, stadiums, urban transport, large department stores, maternity hospitals, high-rise buildings, large enterprises.
Also, a significant benefit of the introduction of a power supply automation system is expressed in a sharp decrease in the downtime of equipment consuming electricity and the associated economic costs.
Automation of engineering equipment of buildings in the field of electric lighting provides, in particular, remote control of lighting using modern gadgets.
Our company specializes in the design, production and installation of automation systems for engineering equipment of buildings. In addition, we integrate reliable automated control systems into existing systems of engineering equipment of buildings, which increases the efficiency of operation of these engineering systems.
