基于公共电话网的环境水域质量远程监测系统的设计

针对环境水域分布广、地势复杂、监测分散的特点，设计了一种基于公共电话网的分布式远程水域质量监测系统。对水质参数采样及软硬件系统设计进行了论述，借助公共电话网解决了遍布各地的现场检测点与信息中心的数据远程通信问题，实现了环境分布水域质量的集中监测。该设计已成功应用于山东省内重点水域水质监测系统中。实际应用表明，该系统成本低，能够实时检测水质参数和提供环境水域质量状态信息，具有一定的推广前景。

Design of Water Parameters Acquisition System Based on Public Switched Telephone Network

According to the widely dispersive water monitoring sites,a remote distributed monitoring system of water parameters is designed based on public switched telephone network.The hardware and software designs of water parameters sampling are introduced.The system solves the data remote transmission problem between distributed points around the test site and information center.And it achieves the centralized monitoring to the quality of distribution water environment by the public switched telephone network.The designs are successfully used in a sewage water monitor system in Shandong province and good results are achieved.Practical application shows that the system can provide real-time detection of water environment and state information of water quality parameters.It is low cost and has a potential market prospect.
