配电网是现代电力系统的重要组成部分。介绍了利用无线传感网(WSN)和ZigBee技术构建的配电网数据采集系统的工作原理，描述了系统的设计方案、硬件设计与软件实现。为提高数据采集的及时性和准确性，采用了中位值平均滤波的方法对测量通道中串入的随机干扰进行滤除，实验证明，该方法无论对于缓慢变化的信号，还是快速变化的信号，都具有良好的滤波效果。

The distribution network is an important part of modern power system. The working principle of data acquisition system for power distribution network was introduced, based on the technology of WSN (wireless sensor network) and ZigBee, and the design scheme, hardware design and software implementation of the system were described. In order to improve the timeliness and accuracy of the data col ection, the median average filtering method was used to filter the random disturbance, which mixed in the measure channel. The experiment proves that the method has good filtering effect not only in slow changing signal, but also in rapidly changing signal.
