Tire pressure monitoring system and BLE tire pressure sensor calibration method

The invention relates to a tire pressure monitoring system and a BLE tire pressure sensor calibration method. The tire pressure monitoring system comprises: a BLE master node; the BLE tire pressure sensor is arranged on a wheel and is used for acquiring state information of a corresponding tire and sending the state information to the BLE main node; the BLE positioning anchor point is installed on a vehicle body of a vehicle and is connected to a vehicle network through a physical connection line, the BLE positioning anchor point sends an ID identifier of the BLE positioning anchor point and the scanned RSSI data of the BLE tire pressure sensor to the BLE main node through the vehicle network, and the BLE main node calibrates the position of a tire where the BLE tire pressure sensor is located based on the ID identifier of the BLE positioning anchor point and the RSSI data. According to the tire pressure monitoring system and the calibration method of the BLE tire pressure sensor, calibration of the tire pres
