轮胎压力信号接收和处理方法及其装置
摘要：
本发明涉及一种轮胎压力信号接收和处理方法和装置。装置包括第一定向天线、第二定向天线、放大器、信号转换器和微控制器。第一定向天线临近该乘用车的其中一前轮，且定向方向指向该乘用车的另一前轮。第二定向天线临近乘用车的其中一后轮，该后轮与该其中一前轮呈对角布置，且第二定向的定向方向指向该乘用车的另一后轮。放大器连接该第一定向天线及该第二定向天线，以分别放大第一定向天线及该第二定向天线所检测的发射器发出的压力信号。信号转换器将无线电信号形式的压力信号转换为场强信号。微控制器接收转换后的各个发射器的场强信号，且根据各个发射器的场强信号的大小确定各发射器所在的轮胎位置。
摘要（英）：

The invention relates to a tyre pressure signal receiving and processing method, and an apparatus thereof. The apparatus comprises a first directional antenna, a second directional antenna, an amplifier, a signal converter, and a microcontroller. The first directional antenna is close to one of the front wheels of a passenger vehicle, and the direction is oriented to the other front wheel. The second directional antenna is close to one of the rear wheels of a passenger vehicle, wherein the rear wheel and the front wheel are arranged in diagonal positions, and the direction of the second directional antenna is oriented to the other rear wheel. The amplifier is connected to the first directional antenna and the second directional antenna, and is used for respectively amplifying the pressure signals transmitted by transmitters and detected by the first directional antenna and the second directional antenna. With the signal converter, the pressure signals in a form of radio signals are converted into field intensity signals. The microcontroller receives the converted field intensity signals of the transmitters, and determines tyre positions of the transmitters according to the field intensity signal strengths of the transmitters.
