基于组态软件的城市轨道交通综合监控系统与火灾报警子系统通信协议研究

Research on Communication Protocol between ISCS and FAS Based on Configuration Software

在城市轨道交通综合监控系统(ISCS)中,火灾报警系统(FAS)是重要的子系统之一。在现场工程实践中,由于各个厂家设备的特殊性,不具备通用的通信协议与驱动,导致组态监控软件无法与设备进行直接通信,因此需要进行定制化开发。提出了一种基于组态软件的ISCS与火灾报警子系统的通信协议,对通信流程进行了介绍,并对报文帧结构进行了分析研究。这一通信协议实现了监控系统与报警子系统之间的数据互通,可实时反馈报警信息,效果良好。

InlSCS, the FAS is one of the important subsystems. In the field engineering practice, due to the specificity of equipment coming from various manufacturers, it is not available to have a common communication protocol and drive, as a result, the configuration monitoring software can not communicate directly with the equipment and it needs to be built to order, presented a communication protocol between ISCS and FAS based on configuration software with an introduction on the communication process and analytical study of the frame structure of the message. This communication protocol realizes the data intercommunication between ISCS and FAS while feeding back the alarm information in real time and its function is good.
