Tire pressure ID code learning device and method of learning ID code

摘要

An ID code learning device includes a RF transceiving module, a received signal strength indication (RSSI) module, and a processing circuit. The RF transceiving module receives RF signals, and each of the RF signals contains an ID code. The RSSI module is electrically connected to the RF transceiving module to detect signal strengths of the RF signals received by the RF transceiving module. The processing circuit is electrically connected to the RF transceiving module and the received signal strength indication module respectively. The received signal strength indication module detects the RF signal with the highest signal strength, the processing circuit pairs the ID code thereof with a predetermined tire location code, and then the RF transceiving module transmits a pairing result out.
