Building Management System
Brief description:
The concept of designing and building a new house in our days has very much evolved with the purpose of living more comfortable and replacing human activity with automation systems.
By means of Building Management System it is understood an hierarchical and distributed control system which includes all the installations in the building and insures the technical and economical administration, realizing an important economy of energetic consumes (power, heating, water, gas, etc).
The utilities from ROMATSA building integrated in
the Building Management System are the following:
1.The electrical power supply (general distribution boards, stand-by Diesel generator units, 20 / 0,4 kV Power Transformers, 20 kV Cells, UPS);
2.The inside and outside electrical installations;
3.The HVAC system the York equipment;
4.The heating boiler and auxiliaries;
5.The water and sewerage station (the wells, the drinking feed water system, the domestic water pumps);
6.The fire feed water system;
7.Security systems: intrusion alarm system, access control system, closed circuit TV system (CCTV), fire detection & alarm system;
8.Other utilities: elevators.
For all the systems of the building that have to be integrated in a BMS, there are provided totally independent automation systems with monitoring, control and protection functions.
They were provided with hardware modules compatible with the European Installation Bus (EIB), witch takes information from/to BMS.
The security and the fire detection and alarm systems will not be included in the Building Management System. They will be entirely independent by maintenance reasons, but the data from them can be displayed in 'the Monitoring Room' of BMS.
The EIB system ensures the general indoor lighting monitoring, starting from the usual functioning under energy saving conditions, up to ensuring operation safety conditions, monitoring the number of running hours, parts replacing and repairs needs, etc
1.BMS functions:
The Building Management System provides the following functions:
- Systems monitoring;
- Graphic interface for the data;
- The archiving of the historical data (events log);
- Alarms logs;
- Reports and parameters curves generation;
- LAN integration;
- Different controls from the dispatch as references settings, hours programming settings for consumes efficiency, on-off controls for local rooms etc.
2. BMS architecture
The architecture of BMS is based on a network modular concept with process interfaces and PCs, using standard operating systems and protocols.
BMS includes the following components:
- A hardware platform with the necessary communication interfaces to the Central Dispatch;
- An independent system to coordinate the subsystems (for time functions, block functions meant to define parameters or references, messages functions to set what, where and when has to be something transmitted).
- Operating systems Windows NT (95, 98, 2000);
- Configuration of software and data base management;
- Communication control software;
- Operator-interface software;
- Reports and parameters curves generation software;
- LAN integration protocol;
- Utilities.
3. Security systems
The most dangerous actions for a building are the specially-made damages, the break-ups, the robberies and the fires.
A specially-made action can bring: losses and damages of equipment, of records, of utilities, of resources (information), staff demoralization, bad publicity with business losses, time-out of activities, person
The security concept can be described as the adoption of some measures for: the company and its goods security against some robberies, the providing of the optimum utilization of the available resources, the providing of the necessary quiet for those who use the building.
The most important security subsystems are:
- Fire detection and alarm system;
- Intrusion alarm system;
- Access control system;
- Closed circuit TV system.
The security subsystems (which can function independently) have to be integrated for a better efficiency, for the information and controls exchange.
Every subsystem can be connected via a bus or its network module to a Local Area Network, e.g. Ethernet Network with TCP/IP protocol; the system can include a server and several workstations.
The Central Control is placed in a dedicated room, (which might include some central equipment of the systems, such as: DF plant, CCTV matrix etc.) where BMS do not exist or inside BMS room.
The complete integration of BMS security systems can be done spatial or computerized by common direct connecting (with specific interfaces) in BMS loop.
