摘要
为了通过计算机和手机终端监测异构污水处理过程,架设了监测专用服务器,通过GPRSDTU模块实现各污水处理点PLC与服务器虚拟串口之间的远程数据透传,通过OPC技术提取各种型号PLC的关键数据分类存入数据库,通过IIS+ASP.NET快速部署Web Service实现数据的远程推送。经实践验证,该方案具有成本低廉、运行稳定、部署快捷、维护方便等特点。
In order to monitor heterogeneous wastewater treatment process by the terminals of computers and cellphones,a dedicated server for monitoring is set up.Remote data pass-through between the PLC of every wastewater treatment station and the virtual serial port of the server is realized by GPRS-DTU module.The key data are extracted from various types of PLCs via OPC technology and stored into database by category.Web Service is deployed rapidly to realize to remote push data via ISS＋ASP.NET.Facts proves that the solution has the advantages of low cost,stable operation,rapidly deploy,convenient maintenance and etc.
