In view of enameled wire film testing equipment of the current market with large size,low efficiency and other shortcomings,this paper designs and develops a hand-held high-pressure paint film detector. After that,the paper also gives its hardware structure and software design method. The detector regards the STC89C51 microcontroller as the core,combined with high-voltage power supply module and leakage current signal detection circuit,displays test information through the digital tube. In addition to small size,the detector also has low cost,low power consumption,high detection sensitivity.Co...
