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.
