摘　　要：地铁站的火灾报警系统(FAS)与环境与设备监控系统(BAS)接口至关重要,结合实际工程项目,根据ESSER第三方通信协议(IDT)的特殊要求,通过串口参数设置、ASCII编程串口数据读取、通讯报文解析、表驱动法实现BAS模式号码计算等详细设计,程序实现了CPU集成串口和ESSER火灾报警主机之间串行通讯,满足消防规范中的要求“联动控制系统在接收FAS报警信息后需在3秒内发出联动控制命令”。程序运行稳定有效,为系统间安全、实时、可靠交互提供了保障。The interface between Fire Alarm System(FAS)and Building Automatic System(BAS)of subway station is very impor-tant.According to the special requirements of ESSER third party communication protocol(IDT),the detailed design of seri-al port parameter setting,ASCII programming serial port data reading,communication message analysis,table driven meth-od to realize BAS mode number calculation is carried out,and the program realizes CPU integrated string the serial com-munication between the interface and the ESSER fire alarm host meets the requirements of the fire code that"the linkage control system shall send the linkage control command within 3 seconds after receiving the FAS alarm information".The program runs stably and effectively,which provides guarantee for safe,real-time and reliable interaction between systems.
