Module for realizing function expansion by combining with metering device

Abstract

The invention relates to a module for realizing function expansion by combining with a metering device, which is provided with a power supply and also comprises a combining part, an internal communication interface and a functional unit, wherein the combining part is used for physically combining with a corresponding expanding and combining part on the metering device; the internal communication interface is used for combining with a data communication interface of the metering device; the functional unit is used for carrying out appointed action processing aiming at the consumption data obtained by a metering unit according to the requirement of a user and/or carrying out the appointed action processing on a metering object according to a preset control command; the protocol of a data communication interface of the metering device is consistent with the protocol of the internal communication interface and is identified by the metering device according to the logical data number of the module for realizing the function expansion by combining with the metering device.

Description

technical field [0001] The invention relates to an expansion technology of a metering device, in particular to a module used in combination with the metering device to realize function expansion of the metering device in use. Background technique [0002] With the development of the economy, the dependence of all fields of the national economy on various resources, especially energy, has been increasing. In order to measure the amount of energy consumption, various metering equipment have emerged, such as electric energy meters, Water meters and gas meters are used to measure water and gas consumption, so how to achieve effective management of the metering site has become a hot direction of continuous innovation in the field of metering. [0003] But the current situation is that the existing metering devices often have relatively single functions. As the energy management department requires more refined management of energy such as electricity, water and gas, it is necessa...

Problems solved by technology

[0003] But the current situation is that the existing metering devices often have relatively single functions. As the energy management department requires more refined management of energy such as electricity, water and gas, it is necessary to add new management functions. , and with the development of science and technology, this function will increase more and more. The existing method is to transform or replace the entire metering device, and adopt a new metering device that integrates the required functions. Therefore, in a large To a certain extent, a huge waste has been generated, and it has also increased the repeated investment costs of the country and corresponding enterprises.

[0004] In addition, although the new metering device used meets the functional requirements of the energy management department, once some functions fail, such as prepayment and ant
