| 中文摘要: |
| 针对轮胎磨耗量检测设备结构复杂、成本高、操作繁琐等问题，开发出基于并联电阻网络、无线收发模块和STC12C5A60S2单片机的实时检测轮胎磨耗量的轮胎磨耗检测系统。该系统利用并联的电阻网络将轮胎磨耗量转换成模拟电压值，并通过模数转换电路将模拟电压值变为便于单片机处理的数字量，最后通过无线收发芯片将数据采集到STC12C5A60S2单片机中进行处理和计算，并将结果显示在液晶显示屏上，从而实现对轮胎磨耗等级的判断和预警。通过轮胎磨耗模拟试验设计，得出轮胎磨耗量与总电阻的倒数呈线性关系，从而实现轮胎磨耗量的测量。 |

| In order to solve tire wear test equipment’s problems of complex structure，high cost and complicated operation，a tire wear detecting system for real-time detecting the wear loss of tire，which was based on shunt resistance network，wireless transceiver module and STC12C5A60S2 MCU was developed.
The system used shunt resistance network to convert the wear loss of tire into the analog voltage，and this analog voltage was changed into digital quantity which was convenient for MCU process by analog-todigital converter. Finally，the data was collected into the STC12C5A60S2 MCU by wireless transceiver to process and calculat. and the result was displayed on LCD screen，thus the judgement of tire wear level and early warning could be achieved. Through the tire wear experiment development，it could be concluded that tire wear loss was linearly related to the reciprocal of total resistance value，thus the measurement of tire wear loss could be achieved. |
