GPRS远程监控的现场总线控制系统

GPRS Remote Monitoring Fieldbus Control System

为了便于超级用户远程监控生产过程,设计手机用户与现场总线控制系统通信方案,即采用网间协议转换器硬集成方法,解决不同协议的现场总线设备与上位控制系统之间的通信问题。在实现Modbus与Profibus-DP、GPRS网络之间的数据透明传输的基础上,完成了S7-400 PLC与Modbus PLC设备之间的数据采集和监视控制,达到了异构现场总线协议设备集成的目的。利用GPRS网络,搭载移动通信网络,构建了一个无线、异地、全天候的现场总线控制系统远程监控系统。

In order to facilitate power users to remotely monitor and control production process,the communication scheme for mobile users and Fieldbus control system was designed,i. e. making use of network protocol converters’ hard integration to realize communication between Fieldbus devices of different protocols and host control system. Basing on transparent transmission of the data among Modbus,Profibus-DP and GPRS networks,the data acquisition and monitoring between S7-400 PLC and Modbus PLC equipments was implemented,including the integration of heterogeneous Fieldbus protocol equipment and using GPRS network and mobile communication network to construct a wireless,remote and all-weather fieldbus control system.
