Self-power-generation inspection robot gas power-off system and control and detection method

The invention relates to the technical field of robots, in particular to a gas power-off system of a self-power-generation inspection robot and a control and detection method.The system comprises an upper computer, a power supply circuit, a switching control circuit and intrinsic safety equipment, and when the gas concentration does not exceed the limit, an intrinsic safety power module supplies power to the intrinsic safety equipment; when the gas concentration exceeds the limit, the switching control circuit switches the power supply circuit to the standby intrinsic safety battery to supply power to the intrinsic safety equipment, the requirement for power failure due to the fact that underground gas exceeds the standard can be met, and the robot can continuously detect the gas concentration and upload the gas concentration in real time after power-off protection. An alarm output signal of the intrinsic safety equipment is led out and connected to a counting starting trigger end of an electronic counter, so
