中文摘要：

设计了一种新型的间接式轮胎压力监测系统，阐述了其工作原理和硬件构成。针对关键技术扭矩振动共振频率的估计问题，提出了基于自适应权值梯度重构算法的共振频率估计法和基于非均匀小波变换的共振频率估计法两种方法，并给出了实验结果。结果表明：前一种估计方法精度高于后一种方法；而后一种估计方法耗时短，节约内存资源。

英文摘要：

A new wheel-speed based TPMS was designed, the design principles and hardware frame were described. To solve the key technology of estimation on torque vibration＇s resonance frequency, two methods, resonance frequency estimation method based on adaptive weights preconditioned conjugate gradient and the method based on non-uniform sampling wavelet transform were presented. The results show that the resolution of the former is higher than the latter＇ s, while the latter one saves time and resource.
