Building management system (BMS)


What is BMS (Building Management System) ?

Central monitoring system allowing:
- acquisition of data, information, signals and statuses from all systems integrated in buildings
- archiving of data into central database (напр. MS SQL Сервер)
- operation and management of buildings with unified operator interface
- conservation of energy resulting from optimalization of heating, energy consumption regulation (control of lights, ventilation, heating, HVAC, и т.д.)

BMS system includes

Monitoring and evaluation of data from security systems:
- elektronic security systems, напр. the Galaxy system
- elektronic fire alarm systems напр. the Esser central (by Honeywell)
- monitoring of other malfunction signals (switchboards, lifts, emergency energy sources, и т.д.)
Monitoring nad regulation of heating and energetic devices
- heating and water boilers
- regulation of boiler rooms and heat exchange stations
- monitoring and regulation of HVAC
- monitoring of operation statuses, control of technologies based on defined time schedules or contractual consumption diagrams
Measurement and evalueation of energy consumption (электричество, вода, тепло, газ ...)
- monitoring and evalueation of energy consumption in defined time range based on specific criteria:
1. based on measured medium type (электричество, вода, тепло, газ ...)
2. based on consumer
3. based on group of meters (напр. boiler room, flat unit, ...)
- monthly evalueation of consumption + possible экспорт of data into information systems
Attendance systems
- integration of personnel attendance systems (напр. Microsoft Access system)
Camera systems (CCTV)
- integration of camera records into the BMS monitoring system (live surveilance, record vieweng, camera control, ...)
Monitoring and control of inteligent houses
- using communication buses DALI, KNX, BACnet и т.д..

BMS system input data

Request for interconnection of BMS system with other systems and devices: Measureent and Regulation (various types of PLCs), energy счетчики (from various manufactureres), subsystems integrated in the building (fire alarms, security systems, cameras ..), connection to devices/buses of intelligent houses (lights, windows, devices, и т.д..). The standard TCP/IP protocol communication is preferable.
Security and fire alarm centrals (напр. Esser, Bosch, ...)
- online data - direct connection via communication interface (Ethernet, RS485 и т.д..) or OPC servers
- history - data access via database interfaces ...
Measurement and regulation systems – monitoring and parametrization of boiler rooms, exchange stations, HVAC units, ...
- communication with PLC devices of various brands (Simatic, SAIA, Mitsubishi, Unitronics, protocols Modbus, M-BUS, PmIEC8705 и and other)
Measurement of energy consumption: automated data reading from various energy meters: Kamstrup MULTICAL, Danfoss INFOCAL-5, ABB, Siemens, и т.д..
- communication by standard protocols Modbus, M-BUS, IEC 60870-5
- remote transmissions using GSM, radio networks, VPN, cloud systems, ...
Database connectivity
- data импортs from attendance systems
- data экспортs into enterprise IS (source data for energy invoicing)
Connection to devices and buses in intelligent houses
- using communication buses DALI, KNX, BACnet и т.д.

System architecture

The most commonly used architecture of BMS systems is клиент-сервер:
Main BMS сервер - provides server services for the whole system:
- Communication сервер – reading data from subsystems in real time
- Data сервер - data archives in central database (напр. MS SQL)
- Web server – generating data for visualization Web clients
Visualization Web clients in BMS
- uniform visualization of all technologies that are integrated in buildings, unified control system (time schedules, ...)
- monitoring of technology operation in the bulding indicating the localization of technological items in individual floors (energy счетчики, fire detectors and sensors, security systems,...)
- ability to render progression of values and statuses of signals in time (trends)
- management of system alarms and events
- reports and data outputs: energy consumption reports, alarm reports, ...
- allows definition of multiple user types with varying rights and permissions:
1. reception – only monitoring, no parametrization access
2. energetics manager, technology manager, building manager, и т.д..
3. system administrator who is able to set system parameters
4. other (as requested by customer): tenants, и т.д..
Web clients advantages:
- independent on OS platform (Windows, Linux, ...) - any Web browser (Chrome, Firefox, Edge, InternetExplorer ..)
- easy system management - no need to install other system software components.
- easy BMS system extension by adding more Web clients
- Web client can be operated on any PC (or other device - smartphone, tablet, ...) connected to the Intranetu. Access to BMS data is protected by passwords and user permissions.
