Today, I will introduce a national invention authorized patent-a smart gas meter with automatic identification function module. The patent was applied for by Chengdu Qianfeng Electronic Instrument Co., Ltd. and was authorized and announced on February 27, 2018. The invention belongs to the technical field of smart gas meters, and particularly relates to a smart gas meter with an automatic identification function module. There are many types of smart gas meters, including ordinary IC card gas meters, RF remote gas meters, and IoT gas meters. The general approach is to design different motherboards for different functions. The disadvantage of this approach is that there are many types of motherboards that need to be designed, high cost, and heavy maintenance workload. The purpose of the present invention is: in order to solve the above problems in the prior art, the present invention proposes a smart gas meter capable of automatically identifying functional modules. The technical solution of the present invention is: an intelligent gas meter that automatically recognizes functional modules, including a control module and multiple functional modules integrated on the main board of the gas meter; the control module is used to send identification signals to each functional module and receive The response signal fed back by each functional module identifies the corresponding functional module according to the response signal; the functional module is used to implement the corresponding function of the gas meter, receives the identification signal sent by the control module and feeds back the response signal to the control module; The control module communicates with each functional module through electrical connections. Further, the control module adopts a CPU. The beneficial effects of the present invention are: the present invention integrates multiple functional modules and CPU on a gas meter mainboard, and uses the CPU to identify each functional module separately, which can realize multiple functions of the smart gas meter and greatly reduce the design cost. And maintenance costs.
