Internet-of-things water meter calibration system

Abstract

An internet-of-things water meter calibration system comprises a water meter calibration table, water level measurement instruments, a camera, flow meters, an industrial personal computer, a computer cloud management system, a handheld inquiry terminal and a two-dimension code scanning gun. Turning on and off of magnetic valves are controlled through the industrial personal computer. After the standard flows of the flow meters are adjusted as required, a constant-flow water supply system performs constant-flow water supply, and water flows into water meters to be calibrated and then flows into the water level measurement instruments. An infrared opposite-radiation device surrounds the calibration table and sends out an alarm signal if man-made interference exists in the calibration process. The internet-of-things water meter calibration system can achieve traverse detection on the water meters and ensure the reliability of the detection process, can also store calibration results and water meter relevant information into a cloud server, enable the calibration process to be trackable and facilitate later-period maintenance and management of the meters.

Description

technical field [0001] The invention relates to the technical field of Internet of Things control, in particular to a water meter verification system of the Internet of Things. Background technique [0002] According to the current "Measurement Law of the People's Republic of China", the working measuring instruments included in the compulsory verification catalog for trade settlement, safety protection, medical hygiene, and environmental monitoring are subject to compulsory verification. The accuracy and stability of water resource measuring instruments, namely commercial and domestic water meters, are of concern to merchants and residents. Therefore, designing a set of Internet of Things water meter verification system is not only convenient for the metrology administrative department to supervise and inspect the quality of the measuring instruments manufactured and repaired, but also to ensure the accuracy of the factory water meter and maintain the vital interests of use...

AI Technical Summary

Problems solved by technology

[0003] At present, the water meter detection method is that the meter manufacturer will perform a self-inspection when it leaves the factory, and the water company will conduct a sampling inspection after receiving the water meter, and the management of the water meter basically belongs to a single local management

Since the water meter cannot guarantee that the manufacturer will perform traversal self-inspection on the meter when the water meter leaves the factory, the water company only conducts a sampling inspection.

Such a verification process cannot guarantee the accuracy of the water meter obtained by the user, and it is not convenient for the later maintenance and management of the meter.
