Testing method, apparatus and system for gas detector

The invention relates to the field of automatic testing technology, and specifically discloses a testing method for a gas detector, which comprises: obtaining an operating voltage signal of a gas detector, and testing a working voltage signal; acquiring a temperature signal of the gas detector, and Testing the temperature signal of the gas detector; controlling the analog probe module to output atleast two different concentrations of gas signals to the gas detector; obtaining corresponding gas concentrations of the gas detectors for different concentrations of gas signals; for each gas signalThe corresponding gas concentration of the output is tested; if the test result of the working voltage signal, the test result of the temperature signal of the gas detector, and the test result of the gas concentration are normal, it is determined that the gas detector works normally. The invention also discloses a testing device and system for a gas detector. The test method of the gas detectorprovided by the invention r
