Abstract：Aiming at the bad real-time function of flicker data's detection and transmission in the energy efficiency evaluation system，a radio communication system of flicker monitoring was designed. According to the method recommended by international electric commission（IEC），WJZ-VI power monitor can collect and process real-time data. In accordance with requirements of working sites， GPRS was used to complete the data's radio transmission. The simulation model was established using the Matlab/Simulink software，

which was up to the IEC standard according to the result of simulation. The results indicate that the monitor system can be effectively incorporated into the energy efficiency evaluation system，which can collect，process and transmit real-time data. And this system can provide technical support for the control of flicker，which has great application value.
