Automatic Ventilation Regulation Equipment for Gas Meter Based on OCR and PLC
In the process of automatic production of intelligent membrane gas meter,according to the process requirements,it is necessary to ventilate the base meter regularly,that is,simulate the actual working state of the gas meter,inject air with a certain pressure from the inlet,and stop the ventilation when the counter normally counts to the preset value.A device based on optical character recognition(OCR)technology and PLC control is proposed and designed.The device can automatically read the counter value and automatically ventilate to make the base meter count to the preset value.At the same time,the device can mark and alarm the base meter with counting defects.
