The Research on Hardware Design for the Automatic Verification System of Late-Model Fuel Dispensers

Article Preview

Abstract:

According to the requirement of JJG443-2006 ,the solution of hardware design of late-model fuel dispensers automatic verification system is introduced in this paper, which makes use of four wire PT resistance and AD7712 as the acquisition circuit for getting temperature of oil tank and oil gun. In order to achieve the automatic verification of fuel dispensers, it also designs the measuring circuit for the flow rate of oil gun based on AD620 chip and the automatic camera module driven by stepper motor.
