摘　　要：火灾报警系统由多个监测站和一个上位机管理站组成。采用VB语言设计上位机管理站工作界面,利用RS-485通信协议实现本地监测站与上位机管理站的通信,并实现对本地监测站的实时监控和温度数据采集,文中阐述了数据通信协议,对数据通信MSComm控件的属性应用进行了详细说明。文中分析研究了上位机管理站主窗体设计界面和显示界面,对历史查询窗口进行了设计。完成了上传温度到上位机管理站程序设计,给出了监测站上传报警上限程序设计流程图。用VB语言实现了上位机管理站上传报警上限界面的设计并可以实现温度曲线绘制。Fire alarm system is made up of monitoring stations and PC management station. The work panel is designed by use of VB language. The communication between local monitoring stations and PC management station is realized by use of protocol based on RS-485. The real monitoring and control for local monitoring stations and temperature collection can be completed. The applica- tion and attribute of data communication MSComm control are described in detail. This paper analyses design panel and display panel of PC management station. Design history searching window. The program of sending temperature to PC management station is accomplished. The flow of sending alarm high limit is given. The panel of sending alarm high limit is designed by use of VB and temperature curve can be displayed.
