摘要： The invention relates to a method and device for receiving and processing tire pressure signals. Said device comprises a first directional antenna, a second directional antenna, an amplifier, a signal converter and a micro-controller. The first directional antenna can be positioned near one of the front wheels of said vehicle, and its orientation points to another front wheel of said vehicle. The second directional antenna can be positioned near one of the rear wheels of said vehicle, said rear wheel and one of the front wheels are arranged diagonally, and the orientation of the second directional antenna points to another rear wheel of said vehicle. The amplifier can be connected to the first directional antenna and the second directional antenna to amplify the pressure signals transmitted by the transmitters and detected by the first directional antenna and the second directional antenna, respectively. The signal converter is used for converting the pressure signals in radio signal format to field strength signals. The micro-controller is used for receiving the converted field strength signals of the respective transmitters, and determining the tire positions where the respective transmitters are installed based on the magnitudes of the field strength signals of the respective transmitters.
