Engineering monitoring Engineering monitoring is the protection of various real estate objects from gas leaks, water leaks, temperature violations, monitoring the technical condition of infrastructure facilities and engineering systems.
The service is provided in cooperation with operational emergency services, where information about any other emergency incident at the monitoring site is transmitted.
Timely detection and prevention of emergency situations not only protects property, but also allows you to significantly reduce the costs of organizations and individuals to eliminate the consequences of certain incidents.
The use of engineering monitoring services in conjunction with security and fire monitoring allows you to significantly reduce the costs of both on-site equipment and monthly maintenance
Engineering monitoring — this service also includes remote operational data collection from various resource metering devices, processing of such data and transfer of the necessary information to the client.
The solution for collecting data from metering devices allows you to quickly monitor the current consumption of resources by the consumer, issue invoices more quickly and accurately, reduce the cost of data collection and control of metering devices, and ensure transparency of relations between supplier companies and resource consumers.
Accurate and timely receipt of information from resource metering devices (water, electricity, heat, gas) allows you to effectively make mutual settlements both with the owners of premises and with suppliers of these resources, avoiding shutdowns and the occurrence of significant debt.
Information and measurement complex “Monitoring and control of life support engineering systems” (MUIS)
is designed for remote control, as well as measuring commercial and technological accounting:
* the amount of heat, water and electricity consumed;
* determination of volumetric, temperature and mass consumption of energy carriers;
* implementation of active monitoring of parameters of energy consumption systems;
* collection, storage and visual presentation, documentation of measurement results and information on energy consumption in commercial settlements between the consumer and energy supply organizations.
The complex is based on the conversion of digital or analog signals of measuring information coming from individual sensors into electronic units of measuring components — calculator of heat, water and electricity meters. Next, the measurement information via communication channels through repeaters enters exchange protocol coordination blocks, which maintain a database of archived data from metering devices, with subsequent transmission of real-time parameters to the server. The server sends current measurement information to the automatic workstation (AWS) of the RCMU dispatcher for visual display of measured parameters in real time.
Documented reports of parameters of heat, water and electricity consumption are generated by the automated workplace based on a request for archived data. The automated workplace also exports processed archived data of measured parameters in database file format to the software of a unified information and calculation center.
When installing automation systems and systems for detecting various energy leaks at engineering power and water supply transmission units, if the parameters deviate from the norm, the dispatcher has the opportunity to make changes, and in exceptional cases, in order to minimize the consequences, even suspend the supply of energy until emergency services arrive.
The MUIS complex includes:
* Measuring components – heat meters of classes C and B in accordance with GOST R 51649?2000 (with primary transducers of flow, pressure and temperature), cold and hot water meters of classes A and B in accordance with GOST R 50193.1?92, AC electric energy meters of classes 1 and 2 according to GOST 30207?94, GOST 26035?83, class 0.5 according to GOST 30206?94;
* Connecting components: wired communication lines via RS-232, RS-485, CAN, Ethernet, etc. interfaces. with the corresponding communication protocol coordination units: DR, BKD-M, BKD-ME, BPDD-RS, BPDD-E, BPDD-RS-485M BPDD-RS-485P, BPDD-RS-485K, BPDD-CAN, Moxa NPort, repeaters USL-A, S, P with subsequent transmission of information via GSM channel, radio channel and fiber-optic and optical communication lines, depending on technical conditions.
* Computing components: database servers, automated workstations (AWS) of the dispatcher: IBM AT-compatible commercially available computers running the Windows operating system, monitors, keyboards, mouse manipulators, speaker systems; SCADA system software «LanMon» consisting of: «Workstation LanMon», «LanMon Server», «OPS DA 2.0 Server», «ODS DA 2.0 Client», «OPS HDA Server», «OPS HDA Client» , “House recorder control program”, “OproisLib”, “ArchTool”; database management system (DBMS) “PostgreSQL”.
* Auxiliary components – lightning protection units, uninterruptible power supplies, printers, etc.
The scope of application of the MUIS complex is technological control, parameter management and commercial accounting in networks and facilities of heat supply, water supply, and electricity supply in industry, energy and housing and communal services. Elements and components of the MUIS complex are produced according to the technical specifications TU 4217?014-27128047?2006 and comply with GOST 12997?84, GOST R 8.596?2002, GOST R 51649–2000.
Functions of the MUIS complex:
* Measurement, processing of measurement results for commercial metering of thermal and electrical energy, cold and hot water, memorization and storage in databases of SPRV, DBMS and display on the workstation of values for the corresponding measurement channels: thermal energy (amount of heat), consumption and quantity (mass , volume) of hot and cold water; water parameters (temperature, temperature difference, pressure); electrical energy and power, operating time of the metering device.
* Display in a user-specified form (numerical value, “progress indicator”, graph, table) current values, controlled parameters of heat-water-electricity supply systems on graphic diagrams of the area, house and archived values for a certain period of time on the display ARM.
* Output to a printing device at the request of the operator of a given schedule, table, report generated by the system on the display of the workstation.
* Monitoring the performance of controlled metering devices with display of their current state on the display of the automated workplace and remote control of installed systems.
* Registration in the electronic log of the automated workplace of all changes in the values of measuring channels or states of technical equipment, the time and date of the value change, the name of the measuring channel.
* Maintaining and correcting system time for the main computing and measuring components of the system.
* Generating graphs based on both instantaneous current parameter values obtained from the LanMon Server SPVR, and on the basis of archived data obtained from the PostgreSQL Server DBMS.
* Generating files with generalized and daily information about consumed energy resources for the billing period.
* Providing multi-level protection of system settings from unauthorized access.
