分布式农村分散污水处理系统分析与研究

Analysis and Research of Distributed Dispersed Rural Areas’ Wastewater Disposal System

结合新农村污水布局分散、规模较小、地形条件复杂、污水不易集中收集等特点。我们采用远程监控技术,该系统由现场数据采集装置、数据传输设备、监控中心软件及监控客户端软件组成。根据分散型新农村特点,该系统的工作过程为通过现场终端数据采集传感器将采集到的各排污指标数据,通过PLC传输给GPRS-DTU,再通过GPRS-DTU接入移动GPRS网络,把数据传送到GPRS网络,利用GPRS网络和互联网的对接口把数据采集设备采集到的数据传送到互联网相对应的固定IP监控中心服务器上,监控中心服务器将数据进行存储,并通过WebService进行发布,对数据信息进行共享。同时监控中心服务器通过实时监控软件将信息实时发布,监控者即可通过连接在互联网上的数据中心服务器浏览数据进行实时监控,同时也可以通过其他监控中心发布的数据接口查看其他监控中心数据。

Combined with the characteristic of scattered new rural sewage layout and its smaller scale, complex terrain conditions, and hard realization of centralized collection of sewage, remote control technique is employed. The system is composed of field data collection devices, data transmission equipments, software of monitoring center and software for monitoring client. Based on the characteristic of distributed new country, the operating process of the system is as follows. First, the data of sewage disposal collected through field terminal da- ta acquisition sensor will be transmitted to GPRS-DTU through PLC, then, the data will be transmitted to GPRS Network through GPRS-DTU connecting into mobile GPRS Network, next, the data collected by data transmission equipments will be transmitted to fixed IP monitoring center server corresponding to internet through using the interface of GPRS Network and internet, afterward, the data will be stored by monitoring center server and be launched through Web Service, finally, the data information will share. Meanwhile, monitoring center server will launch real-time information through real-time monitoring software so that monitors can browse the data through Data Center Server connecting on the internet, and also view other monitor centers' data through the data interface launched by other monitor centers.
