【摘要】 轮胎气压不足将对汽车的安全性、经济性产生不利影响。文中对现有基于MEMS技术分析的基础上,加上可靠性、实用性及性价比的考虑,我们采用Motorola公司的压力传感器进行了TPMS系统的设计。其中对其发射部分、接收部分以及程序的设计进行了比较详细地介绍。同时对TPMS的印制版设计中应注意的问题进行了理论模型的说明和论证。更多还原

【Abstract】 When tyre atmospheric pressure lacks it will gives rise to unfavorably the influence on safety and economic nature of auto-mobile. Based on MEMS technical analysis,reliability, practicality, performance price(cost) ratio, we adopt pressure sensor of Motorola company as design scheme of TPMS. We also introduce launching part, receiving part , programming design flowchart in the TPMS scheme in detail. At the same time, we propose and prove the theory model about the antenna PCB design question.更多还原
