The invention relates to a clock calibration device and method and a tire pressure monitoring system.The clock calibration device is applied to a tire pressure sensing device, a temperature reading module reads the working temperature of the tire pressure sensing device under the condition that the tire pressure sensing device is in an awakening reset state, then a query module queries clock buffer data corresponding to the working temperature, and the clock buffer data are sent to the tire pressure sensing device; the correction judgment module judges whether the clock buffer data is consistent with the initial data or not and generates a judgment result, the correction module obtains clock correction data according to the judgment result, and finally the clock correction module modulates a clock signal of the tire pressure sensing device according to the clock correction data. The frequency of the modulated clock signal reaches the target frequency, so that the tire pressure sensing device can dynamically correct the work cycle offset caused by the temperature change in the working process, and the purposes of prolonging the service life of the tire pressure sensing device and finally improving the reliability of the monitoring system are achieved.

    本申请涉及一种时钟校准装置、方法及胎压监测系统,时钟校准装置应用于胎压感测装置,通过温度读取模块在胎压感测装置处于唤醒复位状态的情况下,读取胎压感测装置的工作温度,然后查询模块查询与工作温度对应的时钟缓冲数据,并由校正判定模块判定时钟缓冲数据与初始数据是否一致,并生成判定结果,校正模块根据判定结果获取时钟校正数据,最终时钟校准模块根据时钟校正数据对胎压感测装置的时钟信号进行调制,以使调制后的时钟信号的频率达到目标频率,如此可使得胎压感测装置在工作过程中对其因温度变化引起的工作周期偏移得到动态校正,进而达到延长胎压感测装置的使用寿命,最终提高监测系统可靠性的目的。
