Metering instrument remote upgrading method based on Internet of Things

Abstract

The invention belongs to the field of metering instruments, and particularly relates to a metering instrument remote upgrading method based on the Internet of Things. In order to achieve the purpose,the technical scheme adopted by the invention is as follows: the metering instrument remote upgrading method based on the Internet of Things comprises the following main steps that: S1, a single-chipmicrocomputer sends service data to a server platform; S2, determining whether upgrading is required or not between the server platform and the Internet of Things module, if so, skipping to S3, and ifnot, skipping to S6; S3, the Internet of Things module downloads upgrading data from the server platform and informs the single-chip microcomputer of the downloading progress; S4, after downloading of the upgrading data is completed, the single-chip microcomputer selects upgrading time and carries out upgrading; S5, after upgrading is completed, the single-chip microcomputer confirms the upgrading result, and the step S1 is executed again. Aiming at the existing Internet of Things, the Internet of Things module which is not used in the past is used as a firmware transceiving function and firmware analysis of the single-chip microcomputer, and remote upgrading of the single-chip microcomputer of the Internet of Things terminal equipment is realized.

Description

technical field [0001] The invention belongs to the field of metering instruments, and in particular relates to a method for remotely upgrading metering instruments based on the Internet of Things. Background technique [0002] Metering instruments based on the Internet of Things use the meter-side microcontroller as the main controller for data collection and command execution. The data flow begins with the single-chip microcomputer, which exchanges data with the IoT module through the serial port, and the IoT module wirelessly connects to the base station set up by the operator and then connects to the cloud platform to realize interactive data collection, management or control commands between the single-chip microcomputer and the cloud platform. The overall system of metering instruments based on the Internet of Things is composed of cloud platform + base station + terminal equipment. [0003] As a terminal of the Internet of Everything, the Internet of Things gas meter...

Problems solved by technology

[0004] However, in the embedded software design process of the motherboard, there are inevitably some unknown bugs, and these bugs may only cause problems under specific circumstances; Need to make some upgrades

However, once the watch is installed in the user's home, it becomes very difficult to remove bugs or function upgrades in the software. If there are many watches involved, it will be difficult to update all of them.
