Online detection system for automatic firefighting execution equipment

The utility model discloses an online detection system for automatic firefighting execution equipment, which is used for detecting the integrity of the execution equipment for starting an electric detonator, an electromagnetic valve and the like of a firefighting valve. The system comprises an execution equipment detection device, wherein an integrated circuit board in the execution equipment detection device is connected with a liquid crystal display screen of a front panel thereof; a function key is arranged beside the display screen; the execution equipment detection device is connected with a network adopting an annular CAN (controller area network) bus; the network can contain 64 execution equipment detection devices; each execution equipment detection device can be connected with 8 pieces of execution equipment of electric detonators or electromagnetic valves; and the system can be connected with a computer system through a CAN gateway and is also suitable for electric detonators and electromagnetic valves in the field of common industry. By adopting a CAN bus technology and a distributed structure, at most 512 pieces of execution equipment can be detected. Remote centralized display can be realized in multiple modes and can be freely expanded according to the measurement point number of the system. The system disclosed by the utility model can reliably work for a long time, and has the advantages of safe detection means, powerful functions, flexible networking, convenience in expansion and the like.
