Abstract： In order to solve the problem of the high cost of laying lines in the energy-based central air conditioning billing system，a wireless technology was investigated in central air conditioning billing system. A design based on ZigBee PRO agreement and the Internet communications' technology was firstly presented. Then a circuit，which is applyed to acquire temperature，was designed according to the project and the wireless transmission part was implemented with the IAR Embedded Workbench software. The system's function was tested. The experimental results show that the program implements the entire wireless billing system which can realize wireless charging，optimize the management and save space.
