The present invention relates to the technical field of gas meters, in particular to a detection method of a wireless transmission control unit, comprising the following steps: S1, putting the wireless transmission control unit into a needle bed of an automatic detection tool, and pressing down a needle bed pressing plate; S2, automatically The detection tool supplies power to the wireless transmission control unit through the needle bed, and the wireless transmission control unit automatically initializes. After the initialization is completed, the wireless transmission control unit sends a request to enter the automatic detection mode to the automatic detection tool through its UART port. If the request passes, then Enter the automatic detection mode; S3, in the automatic detection mode, automatically detect the wireless transmission control unit through the automatic detection tool and according to the set detection steps; S4, save the detection result in the automatic detection tool in a fixed format. The invention solves the problems of expensive devices and low work efficiency in the traditional detection method.
Description
Technical field [0001] The present invention relates to the field of gas meters, and more particularly to a method of detecting a wireless transmission control unit. Background technique [0002] The existing gas meter is to manage the gas company to avoid entering the meter reading, and the Wireless Transmission Control Unit (WTCU) is generally provided to upload data information of the gas tissue. The wireless transmission control unit produced by the factory generally needs quality inspection to ensure that the wireless transmission module can smoothly upload the data information of the gas meter to the gas company. [0003] At present, for the functional detection of the wireless transmission control unit, existing equipment generally uses manual testing, each functional testing requires manual trigger, and its work is low. At the same time, when the tool is used to detect wireless signals, since wireless communication is performed on the same frequency point, the wireless tr...
