In this paper the research is based on DSP and GPRS of electric power quality monitoring system : the TI company high-speed DSP chip on TMS320F2812 is used for data processing, analysis and storage; a high-speed GPRS communication module G24 produced by the MOTOROLA company is used for remote wireless data communication, andRS232 serial communication is used to achieve data information communication between upper monitor. TMS320F2812 digital signal processing chip is taken as the core in this paper, the mutual inductor is used to collect the grid signal, then the resistance to aliasing filter circuit composed of four order infinite gain low pass filter circuit is used to filter the collected signals, after filtering, the signals are sent to conversion chip AD7656 for module transformation; also by using phase lock times frequency characteristics of the circuit, a synchronous sampling signal is sent to A/D conversion chip, and makes the measured signal sampling signal and synchronization effect. Through the AD7656 the output signal, and the output signal can be received and digital signal processor (DSP) analyzed with.
