A method and system for decoupling meter protocols and applications

Abstract

The present invention relates to a method and system for decoupling meter protocols and applications. The method includes: a protocol conversion step: converting the protocol of the data reported by the meter into the meter category to which the meter belongs according to a preset mapping relationship. Unify the protocol, and upload the meter report data after the protocol is converted into the unified protocol to the application layer; the command word conversion step: convert the unified command word issued by the application layer according to the preset mapping rules into The specific command word of the meter is issued to the meter; the unified protocol of the meter category and the code of the unified command word refer to the coding dictionary. The present invention realizes the decoupling of protocols of different types of meters of different types or different manufacturers of the same type and upper-layer applications, so that the same application can access different types of meters of different manufacturers, which improves the versatility of upper-layer Internet of Things applications and saves projects. The cost of implementation is reduced, and the progress of project implementation is accelerated.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and system for decoupling meter protocols and applications. Background technique [0002] In the field of the Internet of Things, one of the key issues is to accept the data reported by the edge device or the front-end data acquisition module through the network, and store this part of the data for analysis by upper-level business applications or directly forward it to other software The module performs analysis and processing, and at the same time forwards the control commands issued by the upper-layer business application to the edge device or the control module through the network. In practical applications, edge devices often come from different manufacturers. For devices that lack a unified industry protocol, such as the smart water meter industry, the protocols provided by meters from different manufacturers are often different. The commands are also differen...

Problems solved by technology

Since the application needs to be bound to the manufacturer’s specific type of meter, the maintenance cost of the upper application is too high. Once the meter of other manufacturers is replaced, the entire application has to be redeveloped, even if several manufacturers’ meters are used. , you have to use and maintain several sets of applications at the same time. Even if you use several different types of meters from the same manufacturer, you may need to use several sets of different applications. Therefore, under the existing technical solutions, the application efficiency is relatively high. low maintenance cost
