[0049] 1. Connect 40 probes to the tooling board through the serial port, and the tooling board and the computer are connected using RS485. After the probes are powered on for a period of time and work stably, the computer uses the production automation APP to send a calibration zero threshold command, and the tooling board forwards the command to each probe. After each probe receives the command, it saves the voltage value at this time and records it as a.

PC sends a command to the sample injector (corresponding to the above-mentioned gas supply device) and the analyzer, asking them to extract the gas in the gas bottle into a sealed box and detect the gas concentration in the sealed box. When the gas concentration stabilizes at 20%LEL, the PC sends a calibration low-security alarm threshold, and the tooling board forwards the command to each probe.

[0068] Step S1602, when the gas detector is powered on for a predetermined time, controlling the moving device to move into a calibration chamber included in the gas detector calibration device to seal the calibration chamber;

[0072] Step S1610, calibrating a calibration value of the gas detector based on the first voltage, the gas standard concentration, and the second voltage;

[0073] Step S1612, saving the calibration value in the gas detector.

[0074] In the above embodiment, when the gas detector is powered on for a predetermined time, the gas detector has reached a stable state. Therefore, the mobile device can be controlled to move into the calibration chamber to seal the calibration chamber. After the calibration chamber is sealed, the gas detector can be controlled to collect a first voltage.

Among them, the gas detector may include an MCU microprocessing unit, a sensor, etc. Controlling the gas detector to collect the first voltage may include collecting voltages multiple times within a certain period of time, and determining the average value of the multiple collected voltages as the first voltage. Similarly, when it is determined that the gas concentration in the calibration chamber is the gas standard concentration, the gas detector can be controlled to collect voltages multiple times within a certain period of time, and the average value of the multiple collected voltages is determined as the second voltage.

[0075] Through the above steps, after the gas detector is powered on for a predetermined time, the mobile device can be controlled to move into the calibration room. When the calibration room is closed, the gas detector can be controlled to collect the first voltage, and the gas supply device can be controlled to deliver gas into the calibration room. When the gas concentration in the calibration room is the standard gas concentration, the gas detector can be controlled to collect the second voltage. The calibration value of the gas detector is calibrated according to the first voltage, the second voltage and the standard gas concentration, and the calibration value is saved in the gas detector, thereby realizing the calibration of the gas detector. Therefore, the problem that the gas detector cannot be calibrated before leaving the factory in the related art can be solved, and the effect of calibrating the gas detector can be achieved.

[0076] Optionally, the execution entity of the above steps may be a gas detector calibration device, such as a controller in the gas detector calibration device, but is not limited thereto.
