摘要：

针对润滑油严重污染会导致汽车动力设备故障的问题,设计润滑油污染度实时检测系统。采用C8051F500单片机作为主控芯片,利用光电传感器TCS3414实现润滑油污染度的实时检测。同时引入电磁塞设计,使得系统可以间接检测润滑油中金属颗粒污染度,从而评估汽车的磨损状况。试验表明,检测系统能够有效地检测润滑油中的整体污染度以及监测汽车动力设备的磨损情况。当光源电压高于6 V时,检测系统几乎不受电源电压变化的影响,具有良好的实用价值。

Abstract: A real-time lubricant quality detection system is designed to reduce severe lubricant pollution that can prevent automobile power equipment from normal operation. The detection system uses a C8051F500 microchip as its main control chip, a TCS3414 photo diode to acquire lubricant pollution data, and a magnetic plug that is introduced to detect the pollution level of metal particles in lubricant so as to evaluate automobile wear conditions. Experiments show that this system can be applied to distinguish lubricant pollution levels as a whole and monitor automotive wear conditions. When LED supply power is higher than 6 V, the system is hardly influenced by the change of supply voltage. The detection system has high practical value.
