Description

Controller assembly and metering device

Technical Field

The utility model belongs to the technical field of metering devices, and particularly relates to a controller assembly and a metering device.

Background

This section provides merely background information related to the present disclosure and is not necessarily prior art.

Along with the development of the internet of things, the intelligent mechanical water meter has higher market share, and the intelligent remote water meter generally requires more than 6 years of service life, so the intelligent remote water meter is generally powered by a lithium battery, and the controller is required to have lower power consumption. At present, when the controller of the metering instrument is produced, after the circuit board is pasted, the power consumption of the whole jointed board can be detected.

However, after the power consumption of the circuit board jointed board is detected in the production process, the circuit board jointed board is subjected to subsequent links such as segmentation, welding, assembly with a shell, glue filling, carrying and the like, and the risk of the problem is high for low-power-consumption products because the power consumption is not retested later. In addition, because the controller of the metering device adopts a battery power supply mode, after the complete meter is produced, the battery begins to consume electric quantity, and the longer the storage time in the factory is, the more electric quantity is consumed.
