Internet of things gas meter with autonomous upgrading function and upgrading method

Abstract

The invention discloses an internet of things gas meter with an autonomous upgrading function. The internet of things gas meter comprises a basis gas meter, a main controller, a communication module and a Flash memory, wherein the basic gas meter and the main controller are mutually connected; the communication module and the Flash memory are connected with the main controller; the main controlleris internally provided with an upgrading bootstrap program code storage area and a normal work program code storage area; the Flash memory is used for storing a gas meter upgrading code sent by the main controller; the upgrading bootstrap program code storage area is used for storing an upgrading bootstrap code; and the normal work program code storage area is used for storing a code when the gasmeter works normally and the gas meter upgrading code read from the Flash memory by the main controller. According to the internet of things gas meter, the upgrading bootstrap program code storage area and the normal work program code storage area are arranged in the main controller of the gas meter, completely independent codes are loaded in the two storage areas, and through matching of the twocodes, the gas meter can be remotely upgraded, so that function extension can be carried out after the gas meter is mounted.

Description

technical field [0001] The invention relates to the field of gas meters, in particular to an independently upgradeable IoT gas meter and an upgrade method. Background technique [0002] The original gas meter only had the function of opening and closing the valve, and the gas volume was recorded manually, and then the user paid the fee. With the further development of the gas meter, IC card meters appeared, which had the function of prepayment, but these IC card meters could not To realize the remote transmission of data, the gas company has a lot of inconveniences in the collection and management of residents' gas consumption information, and then the Internet of Things gas meter that can be remotely monitored appeared on the market. The Internet of Things gas meter is through the GPRS wireless public network. Based on the meter, an electronic controller is installed to realize the comprehensive management platform of gas metering instruments for remote data transmission an...

[0002] The original gas meter only had the function of opening and closing the valve, and the gas volume was recorded manually, and then the user paid the fee. With the further development of the gas meter, IC card meters appeared, which had the function of prepayment, but these IC card meters could not To realize the remote transmission of data, the gas company has a lot of inconveniences in the collection and management of residents' gas consumption information, and then the Internet of Things gas meter that can be remotely monitored appeared on the market. The Internet of Things gas meter is through the GPRS wireless public network. Based on the meter, an electronic controller is installed to realize the comprehensive management platform of gas metering instruments for data remote transmission and control

[0003] From the perspective of the development of gas meters, the emergence of every new idea and technology may bring new applications. The current Internet of Things gas meters can realize the functions of online monitoring and remote control. During the use of gas meters, The gas company will put forward new requirements for the installed gas meters at any time, such as real-time price adjustment, gas consumption forecast, safety precautions, etc. The installed gas meters may not have or have not yet perfected functions, because after the current gas meters are installed, The code can no longer be maintained and upgraded. Once the gas company puts forward new requirements for the gas meter, the gas company must replace the corresponding gas meter, which is undoubtedly a huge waste of resources
