Abstract

The invention discloses a gas meter with a pluggable structure. The gas meter comprises a controller, and the controller comprises a controller shell and a control mainboard arranged in the controller shell; a module pulling and inserting opening is formed in one side face of the controller shell, a switching circuit board is electrically connected to the side, opposite to the module pulling and inserting opening, of the control mainboard, a module is detachably connected to the switching circuit board, and the module is inserted into the controller shell from the module pulling and inserting opening. The switching circuit board is arranged on the side, opposite to the module plugging port, of the control mainboard, and the module is plugged into the controller shell from the module plugging port to be connected with the switching circuit board in a plugging manner, so that the plugging design of the module is realized, and the optimization design of the internal space of the controller shell is also realized; on the premise of not sacrificing the installation number of the modules, the thickness, the length and the width of the whole controller shell can be reduced, and the purposes of reducing the product cost and beautifying the product appearance are achieved.

Description

technical field

[0001] The invention relates to the technical field of gas meters, in particular to a gas meter with a plug-in structure. Background technique

[0002] With the maturity of communication technologies such as NB-IoT, GPRS, and LoRaWAN, smart gas meters that support remote meter reading have gradually become mainstream. Smart gas meters that support remote meter reading are equipped with a communication part to transmit information.

[0003] With the continuous iteration of communication technology, the communication part of the smart gas meter needs to be upgraded to meet the needs of various communication technologies. However, the existing smart gas meter dismantling machine will replace the core circuit board, or simply replace the old gas meter with a new gas meter, resulting in a lot of time and cost waste. However, the gas meters with communication module plug-in function generally have the problem of large size, which affects the appearance of the pro...
