摘　　要：现有燃气系统安全防护系统是通过间接地采集空气燃气浓度来判断燃气系统是否存在安全隐患的情况,这里设计一种燃气系统安全防护装置,该设计通过热电偶和流量传感器实时直接采集燃气系统的运行参数,然后由单片机判断燃气系统的工作状态,进而达到对燃气系统安全起到防护作用。通过仿真本设计能对各种情况做出相应的响应。The existing security protection system for gas system is through the indirect acquisition of gas concentration in the air to determine whether a gas system has hidden trouble. This design scheme is to collect real-time operation parameters of gas system directly by thermocouple and flow sensors,and then judges the working state of the gas system by a single-chip microcomputer to play a role in protection of fuel gas system. The simulation result indicates this system can make corresponding response to various situations.
