MCGS组网智能积算仪的流量监控系统及其串行通信设计

Design of Driver for Serial Communication in Net Formed by Intellectual Flow Totalizers Based on MCGS

利用组态软件MCGS组网自行设计的智能流量积算仪构成蒸汽流量监控系统,它实现了现场数据的数字化通信,具有高级的数据处理功能,节约了开发成本和周期。在对MCGS提供的样例程序中的方法接口和串行读写函数分析的基础上,给出编制设备驱动程序这一关键技术的简便解决方法和步骤,同时也提供了积算仪符合通信协议的中断式通信策略和方案。

Introduced a stream monitor system based on generated software MCGS (monitor and control generated system)that formed with the self-developed intellectual flow totalizer instruments.The field digital data transmission was realized in the network.A serial of advanced functions for data processing were possessed.At the same time,cost and time for developing were saved largely.On the basis of analyses to the method interface and serial port access functions provided in the sample The key for programming of the device driver was given and also putting for ward a scheme with interrupt mode of serial communication according with the protocol in the totalizer.
