Problems solved by technology

[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 an...

Embodiment 1

[0032] Such as figure 1 As shown, the present embodiment provides a self-upgradable Internet of Things gas meter, which includes a base meter and a main controller connected to each other, and also includes a communication module and a Flash memory connected to the main controller. An upgrade boot program code storage area and a normal working program code storage area are provided, wherein,

[0033] The Flash memory is used to store the gas meter upgrade code sent by the main controller;

[0034] The upgrade boot program code storage area is used to store the upgrade boot code;

[0035] The normal working program code storage area is used to store the code when the gas meter works normally, and is also used to store the upgrade code of the gas meter read by the main controller from the Flash memory.

[0036] Preferably, this embodiment also includes one or more of buttons, buzzers, liquid crystal screens and power detection devices connected to the main controller.

[0037...

Embodiment 2

[0041] Such as figure 2 As shown, this embodiment provides an upgrade method for upgrading the self-upgradable Internet of Things gas meter provided in Embodiment 1. After the gas meter is powered on, it is applied to the main controller, including:

[0042] Step S1: run the code in the upgrade boot program code storage area;

[0043] Step S2: Guide the gas meter to upgrade or make the gas meter run normally according to the code stored in the code storage area of ​​the upgrade guide program code storage area.

[0044] Specifically, in step S2, according to the code in the upgrade boot program code storage area, the codes stored in the code storage area to guide the gas meter to upgrade or to make the gas meter operate normally include:

[0045]Check whether there is a gas meter upgrade code in the Flash memory, if not, run the code stored in the normal working program code storage area, otherwise proceed to the next step;

[0046] Burn the gas meter upgrade code in the Fla...

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...
