Gas alarm controller integrating branching and bus

The utility model discloses a branching and bus integrated gas alarm controller, relates to the technical field of gas alarm controllers, and solves the technical problem that a gas alarm controller cannot be connected with a branching and a bus at the same time. The system comprises a central processing unit, and further comprises a preprocessing unit, a bus module and a branching module, the central processing unit is in circuit connection with the preprocessing unit, and the preprocessing unit is further in circuit connection with the bus module and the branching module. According to the utility model, the branch line and the bus can be connected at the same time, the problems of singleness and limitation of the gas alarm controller in use are effectively avoided, the universality is stronger, and the convenience in use and installation is greatly improved. 本实用新型公开了一种集分线和总线于一体的气体报警控制器，涉及气体报警控制器的技术领域，解决了气体报警控制器不能同时连接分线和总线的技术问题。它包括中央处理单元，还包括预处理单元、总线模块和分线模块，所述中央处理单元与预处理单元电路连接，且所述预处理单元还分别与总线模块、分线模块电路连接。本实用新型能同
