摘　　要：介绍了城市地下燃气管道泄漏监测报警系统的设计方案.给出了系统总体设计框图,并具体介绍了基站数据采集器、现场检测子机的设计原理及系统管理软件的设计方法.每个基站可挂接64个现场检测子机,通过直流供电载波技术实现基站与子机之间的数据传输,可实时检测地下燃气管道中指定监测点的可燃气体含量,并将检测数据上传到燃气公司的监控中心,实现城市地下燃气管道泄漏情况的集中监控.The overall design of monitoring and alarming system for underground gas pipe leakage is introduced. Its block diagram is given, and the design principles of the data collector in the base station and the measuring subsystem in the field are described in detail, the design method of the system management software is presented. Each base station can be connected with 64 field measuring subsystems, and the data communica- tion between base station and subsystems is implemented by signal carrier technology with DC power supply. The system can detect the real-time fuel gas content at the specified point in underground pipe net and transmit it to the monitor center in Natural Gas Supply Company. So the system can promote the centralized monitoring and control for the urban underground gas pipe leakage.
