摘　　要：叙述了主从式多机通信问题的解决,详细说明了报警上限修改的流程图,上位机管理站或者监测站均可以修改报警上限,对程序设计思路进行了详细分析与阐述,并给出了上位机管理站报警上限修改画面。对监测站的时间校准程序进行了设计。利用VB语言实现了时间校准程序上位机界面设计。给出了上位机管理站时间校准界面显示。对多个I/O口不同房间的传感器完成写报警上限到传感器的操作进行了程序设计。较好地实现了上位机管理站与监测站的数据通信与管理。The solution of main station and secondary station communication was presented. The flow chart of amending alarm upper limit was described in detail. Alarm upper limit can be amended from management station and monitoring station. The idea of program design was analyzed and expounded. The display panel of alarm upper limit amending form the management station was provided. The time calibration program was designed. The management station menu design of time calibration was realized by VB. The menu display of time calibration was given out. For many I/O pert and different room＇ s sensor, The program of writing alarm upper limit to sensor was designed. The data communication and management of management station and monitoring station can be completed better.
