[0019] That is to say, the monitoring system of this embodiment has a three-layer architecture. The first-layer architecture is the top-layer gas monitoring master control device 01, the second-layer architecture is the middle-layer gas supply monitoring device 010 and the header monitoring device 020, and the third-layer architecture is the bottom-layer detection system (host-end detection device 001, pipeline detection device 002, gas supply equipment device 003, and header detection device 004).
[0020] The signals of the pipeline detection device 002 and the gas supply equipment device 003 are directly transmitted to the gas supply monitoring device 010 and then fed back to the gas monitoring master control device 01. After receiving the signals, the gas supply monitoring device 010, the header monitoring device 020, and the gas monitoring master control device 01 will give corresponding status feedback and instructions.
[0021] Among them, the detection system (host - end detection device 001, pipeline detection device 002, gas supply equipment device 003, header detection device 004) includes a gas probe and a controller. The gas probe is installed on the host - end, pipeline, gas supply equipment, and header to perform gas sampling, information collection, and transmission. The host (user - end) detection system (host - end detection device 001) directly feeds back the signal to the gas monitoring master control device 01. The gas supply monitoring device 010 receives the signals from the pipeline detection device 002 and the gas supply equipment device 003, and feeds back the signals to the gas monitoring master control device 01. The header monitoring device 020 receives the header detection device 004 and feeds back the signal to the gas monitoring master control device 01.

[0023] Furthermore, the gas supply monitoring device 010 monitors the signals of the pipeline detection device 002 and the gas supply equipment device 003, transmits them to the gas monitoring master control device 01, and simultaneously issues control instructions, such as maintaining or stopping the operation of the supply device.
[0024] Furthermore, the header monitoring device 020 monitors the signal of the header detection device 004 in real - time, transmits it to the gas monitoring master control device 01, and simultaneously issues control instructions, such as turning on or off the ventilation function of the header system.
[0025] Furthermore, the host - end detection device 001 in the terminal application scenario directly feeds back the signal to the gas monitoring master control device 01.
[0026] Furthermore, after receiving the signal, the gas monitoring master control device 01 will give corresponding feedback, such as normal state or alarm state, such as giving a host alarm shutdown instruction.
[0027] Furthermore, the multi - type combustible gas leakage control and monitoring system is applicable to the gas supply host of the engine test stand, but is not limited to the field of centralized fuel supply for engines.
[0028] The above - mentioned are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and supplements can be made, and these improvements and supplements should also be regarded as the protection scope of the present invention.
