Automobile tire pressure display

An automobile tire pressure display, which has a host that matches the tire pressure detectors of any brands to achieve monitoring effect, comprising:

• a MCU, with multiple function options, at least including a vehicle selection mode, for selecting the matched vehicle brand freely;
• a judgment mode, for judging whether the received radio frequency signal conforms to the built-in vehicle type protocol or not;
• a low frequency trigger mode, for sending low frequency commands;
• and a radio frequency receiving mode, for receiving the radio frequency signals from the outside;
• a low frequency transmitting unit, electrically connected to the MCU, for sending low frequency commands in low frequency trigger mode to try to wake up the external tire pressure detector;
• a radio frequency receiving/transmitting unit, electrically connected to the MCU, for receiving the radio frequency signals from the external tire pressure detector in radio frequency receiving mode and transmitting it to the MCU for processing;
• a buzzer unit, electrically connected to the MCU, providing state caution sound, so that the owner can know the state of at least one tire instantly;
• a database unit, electrically connected to the MCU, storing the TPMS data of all vehicle series and vehicle types of different years, and at least more than one group of the user's TPMS data;
• and
• a display unit, electrically connected to the MCU, displaying the number matching the tire pressure detector and the real-time pressure and temperature values measured by the tire pressure detector.
