【摘要】 提出利用组态软件MCGS、无线通信手机短消息业务(SMS)和工控总线Modbus通信协议实现发电机系统氢气参数的现场实时监测系统的设计方案。详细介绍了监控系统总体结构图及上位机监控系统的设计和设备构件编制;SMS通过全球移动通信系统GSM(GlobalSystemforMobilecommunication)网络发送信息和接收新信息流程;以Flash型超低功耗16位单片机MSP430F149为控制器核心的通信模块设计和Modbus通信过程。该系统可实时监测发电机系统工况,投运实践证明实时、稳定、可靠。更多还原

【Abstract】 A real-time monitoring system for generator hydric parameters is presented,which applies the configuration software MCGS,radio-communication SMS(Short Message Service) and Mod-bus protocol. The system architecture,superordinate computer design and device component develop-ment are introduced in detail,as well as the transmitting and receiving flow through GSM(Global System for Mobile communication) in the way of SMS. The design of communication module,with Flash-type 16-bit MSP430F149 as controller’s core,and the communication process are also ex-pounded. The proposed system monitors generator’s operating conditions real-timely. Its practices show it stable and reliable,functional real-timely.更多还原
