BMS - Building management system
Building management system (BMS), otherwise known as a building automation system (BAS), is a computer-based control system installed in buildings that controls and monitors the building's mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-Bus, Profibus, and so on. Vendors are also producing a BMS that integrates the use of Internet protocols and open standards such as DeviceNet, SOAP, XML, BACnet, LonWorks and Modbus.
KNX – the Worldwide STANDARD for Home and Building Control
In order to transfer control data to all building management components, a system is required that does away with the problems of isolated devices by ensuring that all components communicate via one common language: in short, a system such as the manufacturer and application domains independent KNX Bus. This standard is based upon more than 24 years of experience in the market, among others with predecessor systems to KNX: EIB, EHS and BatiBUS. Via the KNX medium to which all bus devices are connected (twisted pair, radio frequency, power line or IP/Ethernet), they are able to exchange information. Bus devices can either be sensors or actuators needed for the control of building management equipment such as: lighting, blinds / shutters, security systems, energy management, heating, ventilation and air-conditioning systems, signalling and monitoring systems, interfaces to service and building control systems, remote control, metering, audio / video control, white goods, etc. All these functions can be controlled, monitored and signalled via a uniform system without the need for extra control centres.
In order to transfer control data to all building management components (or smart home devices/functions), a system is required that avoids the problem of having isolated devices speaking 'different languages'.
KNX devices can manage lighting, blinds and shutters, HVAC, security systems, energy management, audio video, white goods, displays, remote control, etc
KNX is also the world’s only open standard for home and building control and is compliant to EN 50090, EN 13321-1 and ISO/ IEC 14543, and has been submitted for Australian standards approval.
Unlike proprietary protocols (which only the manufacturer supports), KNX is an open worldwide standard with over 300 different manufacturers producing products that all inter-work and operate together seamlessly.
KNX works by ensuring all components, devices, features and functions of any building (or outdoor space) communicate via one common language instantly and remotely.
