[0043] The test trigger module includes a trigger switch 2, and the trigger switch 2 is used to trigger the analog gas driving instruction to drive the main control module 1 to output a test signal to the gas detection device.

[0044] In a specific embodiment, the main control module 1 is electrically connected to an input interface 3 and an output interface 4 respectively for reading the gas sensing data and outputting the test signal.

[0046] In an embodiment, the test signal is a digital signal or an analog signal.

[0047] In a specific embodiment, the main control module 1 is electrically connected to a positive electrode interface 5 and a negative electrode interface 6 for connecting an external power supply device.

[0048] In an embodiment, the main control module 1 has a power supply unit, and the power supply unit is electrically connected to the external power supply device through the positive electrode interface 5 and the negative electrode interface 6.

[0052] In a specific embodiment, the display unit 7 is an indicator light.

[0053] In a specific embodiment, the trigger switch 2 is a push-button switch.

[0054] Specifically, the gas sensing data includes parameters such as the type of the gas sensor and the preset high-alarm concentration and low-alarm concentration of the external gas detector for the gas. When the main control module receives the above parameters and generates an analog gas instruction, corresponding instructions can be triggered by pressing the push-button switch. The types of the output test signals specifically include: pressing once is a low-alarm signal, and the indicator light flashes red; pressing twice is a high-alarm signal, and the indicator light is on continuously in red; pressing three times is a fault signal, and the indicator light is on continuously in yellow; pressing four times is to restore the gas concentration to 0 value for triggering again.

[0055] In one embodiment, the test system further includes a firmware upgrade execution module for receiving the firmware upgrade data stored in the upper computer and selectively outputting it to the main control module 1 or outputting it to the gas detection device through the main control module 1 according to the type of the firmware upgrade data;

[0056] And,

[0057] For outputting the device information data stored in the gas detection device read by the main control module 1 to the upper computer.

[0058] Specifically, the firmware upgrade execution module is implemented based on an IAP technology for online updating and programming the firmware of the device during the operation of the application program, so as to realize the online remote update of the main control module and / or the gas detection device, and without disassembling the device or interrupting the operation, greatly improving the upgrade efficiency and convenience.

[0059] In one embodiment, the firmware upgrade execution module includes a communication interface 8 for connecting to the upper computer and a communication unit for distributing the firmware upgrade data received by the communication interface 8.

[0060] In a specific embodiment, the communication interface 8 is a USB interface.

[0062] Specifically, the communication interface can facilitate the firmware upgrade of the main control module and the gas detection device, and can also facilitate the traceability of the gas detector.

[0063] The test system for a gas detection device proposed by the present invention, by setting a main control module for reading gas sensing data stored in the gas detection device and generating an analog gas driving instruction, and a test trigger module including a trigger switch, enables the trigger switch to be used to trigger the analog gas driving instruction to drive the main control module to output a test signal to the gas detection device. Compared with the existing test methods, the test system for the gas detection device of the present invention uses an analog gas method to implement the test of the gas detection device, which can ensure the operation safety of the tester, is simple to operate, has higher test efficiency, and effectively reduces production costs.

[0064] Furthermore, the test system for the gas detection device of the present invention is provided with a firmware upgrade execution module, which is used to receive firmware upgrade data stored in the upper computer and selectively output it to the main control module or output it to the gas detection device through the main control module according to the type of the firmware upgrade data; and, it is used to output the device information data stored in the gas detection device read by the main control module to the upper computer. Thus, it is convenient to upgrade the firmware of the gas detection device and trace the source, which is beneficial to the maintenance operation of the gas detection device.

[0068] A housing 9, the main control module 1, the trigger switch 2, the display switch 7, and the communication interface 8 are all arranged inside the housing 9, and the input interface 3, the output interface 4, the positive electrode interface 5, and the negative electrode interface 6 all extend outwards from the bottom of the housing 9.

[0069] When the test device of the present invention is in use, the tester can first dock the bottom of the housing with the interface of the gas detection device, so that the input interface 3, the output interface 4, the positive electrode interface 5, and the negative electrode interface 6 are connected to the gas detector.
