The invention relates to building air-conditioner control system based on a ZigBee wireless technology. The building air-conditioner control system at least comprises a plurality of wireless air-conditioner temperature-humidity sensor modules, a wireless indoor temperature-humidity regulator, a plurality of wireless valve modules, a plurality of wireless switch modules, a wireless gateway and a building temperature-humidity controller, wherein the wireless air-conditioner temperature-humidity sensor modules, the wireless indoor temperature-humidity regulator, the wireless valve modules, the wireless switch modules and the wireless gateway form a wireless communication network based on the ZigBee wireless technology. Accordingly, temperature-humidity data, and the like of all air conditioners can be effectively acquired, and the air conditioners are effectively regulated and controlled, thereby realizing energy saving. Compared with the traditional wired system, the invention has the advantages of low cost, low power consumption, easy installation, flexible application, and the like and has strong expansibility.
Description
technical field [0001] The technology of the invention relates to a building air-conditioning control system, in particular to a building air-conditioning control system based on ZigBee wireless technology. Background technique [0002] With the development of computer technology, control technology and communication technology, the building automation industry has achieved great development in the past ten years, and the building control products following the standardized communication protocols of BACnet, LonTalk and EIB occupy a dominant position in the industry. The communication transmission medium (such as twisted pair, coaxial cable and fiber optic cable) adopted by the building automation network using these communication protocols is usually wired. Compared with building control products using wired network communication technology, the most attractive features of wireless solutions are the flexibility of installation layout, low installation costs and mobility whe...
