摘　　要：介绍了一种基于电阻抗原理的水质快速检测系统。高速微控制器实现电极选通、数据采集并与PC机进行数据通信;PC机作为主控机控制下位机工作,并通过GPRS模块实现远程数据通信。实验结果表明:该系统基本满足对水质检测的性能要求,通过对系统软硬件的进一步改进和完善,可望实现对工业废水实时快速检测的目标。A water quality fast-test system based on the theory of electrical impedance is introduced. High-speed microcontroller carries out the tasks, such as electrode seiection, data acquisition and data communication with PC; The master PC is responsible for the slave machine and long-distance data communication can be carried out by GPRS unit. The test results show that the system can satisfy the requirement of water quality test. By improving the hardware and software of system, it＇s likely to get the aim of real-time and fast-testing industrial liquid waste.
