An tire air pressure monitoring system is provided configured to reduce the information amount of signals transmitted and received by a vehicle-mounted radio device and a vehicle-mounted communication device, and prevent a processing delay and a improve reliability of air pressure information. The tire air pressure monitoring system includes an air pressure acquisition unit that acquires the air pressure of a tire, a vehicle-mounted radio device wirelessly transmits a signal regarding the air pressure acquired by the air pressure acquisition unit, and a vehicle-mounted communication device in a separate location from the vehicle-mounted radio device and receives the signal transmitted by the vehicle-mounted radio device. The vehicle-mounted radio device includes a calculation unit calculating a temporal change amount of the air pressure acquired by the air pressure acquisition unit, and a transmission unit that transmits a signal indicating the air pressure change amount calculated by the calculation unit.
A tire air pressure monitoring system comprising an air pressure acquisition unit that acquires an air pressure of a tire of a vehicle, a vehicle-mounted radio device that wirelessly transmits a signal regarding the air pressure acquired by the air pressure acquisition unit, and a vehicle-mounted communication device that is provided at a different location from the vehicle-mounted radio device and receives the signal transmitted by the vehicle-mounted radio device, the tire air pressure monitoring system monitoring air pressure based on the signal received by the vehicle-mounted communication device,
A vehicle-mounted radio device comprising an air pressure acquisition unit that acquires an air pressure of a tire of a vehicle, the vehicle-mounted radio device wirelessly transmitting a signal regarding the air pressure acquired by the air pressure acquisition unit, the vehicle-mounted radio device comprising:
