Water meter function self-checking device and method

Abstract

The invention provides a water meter function self-checking device and method. The water meter function self-checking device comprises a self-checking module and a reading module. The self-checking module comprises a detection unit and a fault code output unit; the detection unit comprises a storage detection unit, a module communication detection unit, a valve detection unit, an AD conversion detection unit and an LED display detection unit. The fault code output unit stores a plurality of fault codes, responds to fault signal output of the detection unit and displays the corresponding faultcodes; the reading module comprises an image acquisition unit, an image processing unit and a reading unit, and is used for carrying out data extraction processing on the fault code display area and the water meter reading display area to obtain the fault codes and the water meter reading. The maintenance personnel can get the corresponding fault information, and a water meter is maintained in a targeted manner according to the corresponding fault information, so that the water meter fault solving efficiency is improved.

Description

technical field [0001] The invention relates to water meter technology, in particular to a water meter function self-inspection device and method. Background technique [0002] Human life is inseparable from water. Every household has a water meter to record the monthly water consumption of the family. If there is a problem with the water meter, the recorded data will be inaccurate, which will lead to the loss of tap water or users. Therefore, every water company Every month, a large amount of manpower needs to be dispatched to every household in the community to overhaul the water meters. [0003] Because the working environment of the water meter is very harsh, it has a great impact on electronic components and is prone to various failures. Therefore, the safe operation of the water meter and the rapid detection and treatment of faults are of great significance to the safe operation of the entire system. The problems that often occur in water meters include valve opening...

AI Technical Summary

Problems solved by technology

The problems that often occur in water meters include valve opening and closing failures, display failures, etc. The current overall technical level of circuit board manufacturing in the water meter industry is not high, and most of them are manually operated. It was impossible to know what was wrong with the water meter before, and it was impossible to quickly solve the fault in a targeted manner, resulting in low efficiency
