| 摘 要： | 以GPRS网络的供热远程监测系统为背景,针对宏电H7118型GPRSDTU模块,在MCGS组态环境下采用ActiveDLL构件的方式和规范的OLE接口挂接,开发了驱动程序。同时,利用VisualBasic与MCGS脚本混合编程实现数据提取和处理。实践证明,该驱动程序很好地完成了MCGS与GPRSDTU模块的联接,实现了中心站对多从站的采集驱动。采用本驱动程序可缩短软件开发周期、提高系统运行效率。

| Abstract: | The development and application of "Hong Dian" H7118 GPRS DTU driver is described in this paper.It is actualized with the Active DLL,and hanged up into MCGS through a standard OLE interface.A hybrid programming method is adopted to realize data acquisition and processing in practice.The application which uses GPRS DTU in a remote monitoring system of heat supply shows that the device driver works well and realizes the driving from the master station to multi-slave stations.Using this device driver can short the development period and increase the efficiency of operating system. |
