For lack of the effective means of power quality monitoring with the traditional laboratory, this paper put forward a new quality monitoring system based on WSN technology. It consists of energy acquisition node, wireless transmission network and the monitoring center, the wireless network is built by Zigbee technology and GPRS technology. Using AT7022B as the core of the acquisition node, and optimize the routing nodes that composed of CC2530. The results shows that the corrected transfer rate of the system is up to 99 percent, and the system is reliable, flexible networking, low power consumption, it can effectively improved the laboratory power management .
