| Abstract: | A method was described for detecting the resistance variety of switch touch-point and conductor contact point with an infrared temperature sensor indirectly.In this system,PC104 is used as host computer for data processing and logic analyzing.P89C58 SCM is used as slave computer for temperature signal processing and A/D conversion.RS485 bus is used to form a distribution collecting and central processing system.It can detect the resistance of switch touch-point or conductor contact point,and can predict hidden trouble,and take action to avoid power failure. |
