Vehicle Tire Monitoring System (tpms) And Its Host Circuit Design

TPMS is the abbreviated form of Tire Pressure Monitor System, which isused tomonitor in-tire parameters of pressure and temperature, it can checkthe abnormality accurate, and report them to the driver of the car when thetires are in bad condition, this is useful to avoid the accident. TPMS makesautomobile to be more comfortable, more safely and more smoothly. TPMS iscomposed of terminal and basis station. This paper introduces the basedresearch and design of TPMS in detail, including the design of hardwarestructure and software function.Following is the research process: 1) research the relations between tirelosses, tire mangles usually appeared in kinds of cars and tire pressure, tiretemperature; 2) definite the bygone development, present condition and thefuture development of the TPMS; 3) improve the structure of basis station,and explain the advantages that compares to used structure; 4) finish thesystem principle, structure illustration and the design process of thehardware and software of basis station; 5) formulate basis test methord andprocesses ,and analyse the tset results of system, then obtain lastconclusion.According to the testing of lab-conditions, basis station can communicatewell with terminal; it proved to be with good performance.
