Dual-high-frequency loop tire pressure monitoring system

The invention discloses a dual-high-frequency loop tire pressure monitoring system, which comprises a wireless emitting module and a vehicle-mounted BCM; the wireless emitting module is in formation interaction with the vehicle-mounted BCM, and sends a high frequency signal to the vehicle-mounted BCM; the vehicle-mounted BCM receives the high frequency signal from the emitting module and then sends a feedback signal to the wireless emitting module. By using the two-high-frequency signal, the tire pressure emitting module is commonly connected with the vehicle-mounted BCM to form the feedback loop system. The dual-high-frequency loop tire pressure monitoring system has the advantages that 1, the signal transmission is more stable, and the real-time emission is carried out through the feedback loop, and the real-time monitoring is realized when the vehicle is operated; 2, for the signal is received by the vehicle-mounted BCM, complex wires and display goods on the vehicle are reduced. 本发明公开了种双高频回路胎压监测系统，包括无线发射模
