Engineering monitoring.
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, engineering systems.
The service is provided in cooperation with emergency services, to which information about a particular emergency at the monitoring facility is transmitted.
Timely detection and prevention of emergency situations not only ensures the protection of property, but also allows to significantly reduce the costs of organizations and individuals for the elimination of the consequences of certain incidents.
Using engineering monitoring services together with security and fire monitoring allows to significantly reduce the costs of both facility 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 for prompt control of the consumer's current resource consumption, more prompt and accurate billing, reduction of the cost of data collection and control of metering devices, and ensuring transparency of relations between supplier companies and resource consumers.
Accurate and timely receipt of information from resource metering devices (water, electricity, heat, gas) allows for effective settlements with both property owners and suppliers of the specified resources, preventing shutdowns and significant debt.
The information and measuring complex «Monitoring and Management of Life Support Engineering Systems» (MUIS)
is designed to implement remote control, as well as measurement of commercial and technological metering:
* the amount of consumed heat, water and electricity;
* determination of the volume, temperature and mass flow rate 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 measurement information coming from individual sensors to the electronic units of the measurement components — heat, water and electricity meter calculators. Then the measurement information via communication channels through repeaters comes to the units for coordinating exchange protocols, which maintain a database of archived data from metering devices, with subsequent transmission to the server of real-time parameters. The server sends the current measurement information to the automatic workstation (AWS) of the RCMU dispatcher for visual display of the measured parameters in real time.
Documented reports of heat, water and electricity consumption parameters are generated by the AWS based on a request for archived data. The AWS also exports processed archived data of the measured parameters in the format of database files to the software of the unified information and accounting center.
When installing automation systems and systems for detecting various energy leaks at utility nodes for power and water supply transmission, if the parameters deviate from the norm, the dispatcher has the ability 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 according to GOST R 51649?2000 (with primary flow, pressure and temperature converters), cold and hot water meters of classes A and B according to GOST R 50193.1?92, AC electricity 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 exchange protocol matching units: DR, BKD-M, BKD-ME, BPDD-RS, BPDD-E, BPDD-RS-485M BPDD-RS-485P, BPDD-RS-485K, BPDD-CAN, Moxa NPort, USL-A, S, P repeaters with subsequent transmission of information via a GSM channel, a radio channel, and fiber-optic and optical communication lines, depending on the technical conditions.
* Computing components: database servers, automated workstations (AWP) of the dispatcher: IBM AT-compatible serially produced computers running the Windows operating system, monitors, keyboards, mouse manipulators, acoustic systems; SCADA system software «LanMon» consisting of: «AWP LanMon», «Server LanMon», «Server ORS DA 2.0», «Client ORS DA 2.0», «Server ORS HDA», «Client ORS HDA», «Control program of the house registrar», «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 objects of heat supply, water supply, electricity supply in industry, energy and housing and communal services. Elements and components of the «MUIS» complex are manufactured according to technical specifications TU 4217?014-27128047?2006 and comply with GOST 12997?84, GOST R 8.596?2002, GOST R 51649–2000.
Functions performed by the «MUIS» complex:
* Measurement, processing of measurement results for commercial metering of heat and electric energy, cold and hot water, memorization and storage in SPRV, DBMS databases and display on the automated workplace of values for the corresponding measurement channels: heat energy (quantity of heat), flow rate and quantity (mass, volume) of hot and cold water; water parameters (temperature, temperature difference, pressure); electric energy and power, operating time of the metering device.
* Display in the form specified by the user (numerical value, «progress indicator», graph, table) of current values, controlled parameters of heat-water-electricity supply systems on graphic diagrams of the district, house and archived values for a certain period of time on the automated workplace display.
* Printing of a specified graph, table, report generated by the system on the ARM display at the operator's request.
* Monitoring the operability of controlled metering devices with display of their current state on the ARM display and remote control of installed systems.
* Registration of all changes in the values of measuring channels or states of technical equipment, time and date of change of value, name of the measuring channel in the ARM electronic journal.
* Maintenance and correction of system time for the main computing and measuring components of the system.
* Generation of graphs constructed on the basis of both instantaneous current values of parameters obtained from the LanMon Server SPRV and on the basis of archived data obtained from the PostgreSQL Server DBMS.
* Generation of files with generalized and daily information on energy resources consumed over the billing period.
* Ensuring multi-level protection of the system's setting parameters from unauthorized access.
