【摘要】 针对TPMS(轮胎气压监测系统)中低频通信链路中存在的通信距离短和数据传输率不高的问题,提出了采用全桥驱动和利用开关电路快速、适时释放低频谐振电路中残留磁场能量的改进方案,实验结果显示论文提出的改进方案有效地提高了低频发射与接收单元之间的最大通信距离,也使得该低频通信链路能适应更高的比特传输率。更多还原

【Abstract】 An improved programme is proposed to release the vestigial magnetic energy in low-frequency resonant circuit employing full-bridge driver and switching circuit quickly and timely in the light of the problems of short communication distance and low data transmission rate in low-frequency communication links in TPMS(Tire Pressure Monitoring System).The experimental results demonstrate that the novel programme effectively increases the maximum communication distance between the low-frequency emission and the receiving unit,and make the low-frequency communication links adapted for higher bit transmission rate.更多还原
