汽车在高速公路上行驶由于爆胎而引发的交通事故成了“头号杀手”，要提高行车的安全性就要对因汽车轮胎漏气、充气压力不足或充气压力过大等引发轮胎爆胎的异常状况进行监测。因此轮胎压力检测(TPMS)系统已经越来越受瞩目，但目前市场上 TPMS 成本高、价格贵。为了降低系统的成本，引入了 LF 低频唤醒技术，设计了一款集低功耗、抗干扰、低成本等优点于一体的基于 PIC 系列单片机的汽车轮胎 TPMS。通过实验仿真，该系统能够检测汽车轮胎压力状况等信息，具有高性价比和一定的开发价值。
汽車在高速公路上行駛由于爆胎而引髮的交通事故成瞭“頭號殺手”，要提高行車的安全性就要對因汽車輪胎漏氣、充氣壓力不足或充氣壓力過大等引髮輪胎爆胎的異常狀況進行鑑測。因此輪胎壓力檢測(TPMS)繫統已經越來越受矚目，但目前市場上 TPMS 成本高、價格貴。為瞭降低繫統的成本，引入瞭 LF 低頻喚醒技術，設計瞭一款集低功耗、抗榦擾、低成本等優點于一體的基于 PIC 繫列單片機的汽車輪胎 TPMS。通過實驗倣真，該繫統能夠檢測汽車輪胎壓力狀況等信息，具有高性價比和一定的開髮價值。

The traffic accidents caused by tire has become “the first killer”when cars driving on the expressway.In order to improve the safety of driving,The effectively monitor system of the abnormal condition of the automobile tire, such as burst,leakage ,inflation pressure and excessive inflation pressure is needed.And the TPMS system has been more and more popular,but the current TPMS in market have high cost and price.So a system with low-power,anti-interference,low cost and other advantages is designed in this paper.The LF wake-up technology is introduced in the system which based on the PIC Series MCU.Through simulation experiments,the system can achieve the automobile tire pressure detection index .So it has high performance price ratio and certain development value.
