The invention relates to a wireless tire pressure detection system capable of automatically positioning, which comprises a plurality of tire groups divided into a plurality of detected areas; a plurality of sensors which are respectively provided with exclusive ID (Identity) identifiers and are respectively arranged in the detected areas, wherein each sensor automatically transmits an RF packet signal with the ID identifier within a preset time to transmit the RF packet signal; or, transmits an RF packet signal with the LF low-frequency signal and the ID identifier; two receiving devices, wherein the plurality of sensors are respectively arranged in a predetermined detected area, each receiving device is provided with an LF low-frequency trigger for emitting and transmitting the LF low-frequency signal to be received by sensors in each tire group in a predetermined detected area; the sensors are excited through the LF low-frequency signals and are enabled to send the RF packet signal with the LF low-frequency signal and the ID identifier generated after detection in real time so that the RF packet signal is used for being received by the receiving devices for storage operation, andthe position information of tires where the sensors are installed can be accurately and automatically judged through matching application of the sensors and the receiving devices or matching application of the sensors and a plurality of ABS sensors.
Description
technical field [0001] The present invention relates to a wireless tire pressure detection system capable of automatic positioning, in particular to a wireless tire pressure detection system capable of automatically judging the position information of the tire on which the sensor is installed. Background technique [0002] A tire pressure monitoring system (TPMS) generally includes a plurality of tire pressure monitoring devices installed on tires of a vehicle, and is used to detect whether each tire has abnormal tire pressure. Since the 1980s, tire pressure detection devices have been installed in some European car models. In recent years, the United States, the European Union and South Korea have stipulated that all new cars must be equipped with tire pressure detection devices to ensure driving safety. Japan, China and India are also expected to implement relevant regulations in the near future. Taiwan also stipulates that all cars produced after July 2016 must be equip...
