The invention provides a tire pressure signal processing method and a device thereof, and the method comprises the steps: determining operation frame data, first data and an actual baud rate according to a pre-obtained original tire pressure signal and pre-obtained signal level state data; determining a baud rate clock according to the actual baud rate; collecting first data in a time range corresponding to the special-rate clock as second data; determining synchronous frame data and third data according to a preset format configuration rule, a preset length configuration rule and the second data; and enabling the operation frame data, the synchronous frame data, the third data and the actual baud rate to serve as processed tire pressure signals, and sending the processed tire pressure signals sent to a preset detection circuit. According to the method, effectiveness detection and synchronism matching can be carried out on the original tire pressure signal, and the tire pressure state detected by a follow-up circuit is more accurate.
本发明提供了一种胎压信号的处理方法和装置,该方法包括:根据预先获取的原始胎压信号和预先获取的信号电平状态数据,确定运行帧数据、第一数据和实际波特率;根据实际波特率,确定波特率时钟;采集特率时钟对应的时间范围内的第一数据,作为第二数据;根据预设的格式配置规则、预设的长度配置规则以及第二数据,确定同步帧数据和第三数据;将运行帧数据、同步帧数据、第三数据和实际波特率作为处理后的胎压信号,将处理后的胎压信号发送至预设的检测电路。本方法能够对原始胎压信号进行有效性检测以及同步性匹配,有助于后续电路检测到的胎压状态更加精确。
