KNX 簡介 KNX – 住宅和樓宇控制領域
|
KNX是家居和樓宇控制領域唯一的開放式國際標準,是由歐洲三大總線協議EIB,EHS BatiBus和合併發展而來; KNX 技術是對所有住宅和樓宇控制方面的應用開放的通訊協定,這些應用中包括照明和多種安全系統的關閉控制、加熱、通風、空調、監控、報警、用水控制、能源管理、測量以及白色家電、影音系統及其他眾多領域。這項技術可以應用在現有的和最新的住宅和樓宇中。 KNX EIB協議以為基礎,兼顧了BatiBus和EHS的物理層規範,並吸收了BatiBus和EHS中配臵模式等優點,提供了家居和樓宇自動化的完全解決方案.KNX擁有可由廠家獨立設計和測試工具(ETS);提供多種通信介質(TP,PL,RF和IP);提供多種系統配臵模式(A,E,S模式)通過KNX總線系統,對家居和樓宇的照明。遮光/百葉窗,安防系統,能源管理,供暖,通風,空調系統,信號和監控系統,服務界面及樓宇控制系統,遠程控制,計量,視頻/音頻控制,大型家電等進行控制。 KNX的優勢

KNX 產品系列: (按我) YE00819,YE00820, YE00905, YE00906 What is the KNX system? The KNX system is a bus system for building control. This meansthat alldevicesinaKNX system use the same transmission method and are able to exchange data via a common bus network. This has the following consequences: • Access to the bus network needs to be clearly regulated (bus access method) • Mostofthe data transmitted are not payloads (e.g. light on/light off signals), but address information (i.e. where have the data come from? Where are they going to?) Another important feature of the KNX bus system is its decentralised structure: there is no need for a central control unit, because the “intelligence” of the system is spread across all of its devices. Centralised units are possible, however, for realising very specialised applications. Every device has its own microprocessor. A major advantageofKNX’sdecentralised structure is that, if one device fails, the others continue to function. Only those applications dependent on the failed device will be interrupted. Generally in a KNX system, devices fall into three categories: system devices (power supply, programming interface, etc.), sensors, and actuators. Sensors are devices that detect events in the building (e.g. someone pressing a button, someone moving, a temperature falling above or below a set value, etc.), convert these into telegrams (data packets), and send them along the bus network. Devicesthat receive telegrams and convert the commands embedded in them into actions are known as actuators. Sensors issue commands, while actuators receive them (Fig. 4). |
