Tire pressure monitoring system based on BCM and TPMS response circuit

The invention discloses a tire pressure monitoring system based on a BCM and TPMS response circuit. The tire pressure monitoring system comprises an emitting module and a vehicle-mounted BCM, a communication circuit is formed between the emitting module and the vehicle-mounted BCM and used for signal transmitting of pressure and temperature , the vehicle-mounted BCM emits signaling activation to the emitting module, and the emitting module directly sends tire pressure and temperature signals to the BCM; and the vehicle-mounted BCM conducts displaying and corresponding treatment after receivingthe signals. The tire pressure monitoring system is signal response between the vehicle-mounted BCM and the emitting module, the BCM is utilized to send an activation code, and the emitting module sends the data to the BCM after receiving the activation code. The tire pressure monitoring system based on the BCM and TPMS response circuit has the advantages that 1, signal transmission is more stable, real-time emission is
