ABSTRACT:
An automobile tire pressure monitoring system and tire identification method that includes a transmitting and detecting unit provided on each tire, as well as a receiving and display unit that includes a receiving unit, a main control unit and a display unit. A plug-in encoding memory is plugged into the receiving and display unit. One fixed ID code, which is the same as that for the encoding memory, is provided for each transmitting and detecting unit. When the power is on, the receiving and display unit reads the ID code in each plug-in encoding memory plugged into the socket of the display unit, and saves the information on the corresponding relationships between ID codes saved in memories and the tire identity. After receiving the signal from the transmission unit, the receiving and display unit reads the ID codes in it, and determines whether these codes are identical with those in the memories. If the signal is valid, the receiving and display unit compares the corresponding relationships, determines on which tire the detection unit is transmitting the signal, and displays the information about pressure and temperature in corresponding display areas.
