GPRS监管的多协议异构现场总线控制系统

Multi-protocol heterogeneous fieldbus control system regulated by GPRS

目前现场总线控制系统通常只支持一种或两种现场总线协议。针对现场总线协议标准与总线设备种类众多的现状,以支持多种协议为目的,构建由监控级、控制级与现场设备级3层结构的多协议异构兼容的现场总线控制系统。通过网关配置解决PROFIBUS-DP与PROFIBUS-PA、HART、Modbus、DeviceNet和GPRS等异构现场总线的通信问题,建成以西门子PCS7作为上位监控系统,由异构控制器作为现场控制系统的现场总线监控系统,通过GPRS实现移动终端对现场总线控制系统(fieldbus control system,FCS)和现场总线智能仪表无线、实时的嵌入式远程监控功能。试验结果表明,监控级能够远程实时地监管和控制多种协议的异构现场总线设备,实现了对现场总线设备的远程管理和启停控制。本系统可作为多协议异构兼容的FCS的可行性验证。

The current fieldbus control system usually only supports one or two kinds of fieldbus protocols.In view of the current situation that there were many standards of fieldbus protocols and many types of bus devices,a multi-protocol heterogeneous compatible fieldbus control system with three layers of monitoring level,control level and field equipment level was constructed for the purpose of supporting multiple protocols.By configuring gateway to solve the communication problems of heterogeneous fieldbus between PROFIBUS-DP and PROFIBUS-PA,HART,Modbus,DeviceNet,GPRS,etc.,a fieldbus monitoring system with Siemens PCS7 as the upper monitor system and heterogeneous controller as the field control system was built,and the wireless and real-time embedded remote monitoring function of FCS and fieldbus intelligent instrument was realized by GPRS.The test results showed that the monitoring level could monitor and control heterogeneous fieldbus devices with different protocols remotely and real-time,and realize remote management and start-stop control of fieldbus devices.This system could be used as the feasibility verification of multi-protocol heterogeneous compatible FCS.
