TIRE PNEUMATIC PRESSURE MONITORING DEVICE AND EXTERNAL COMMUNICATION DEVICE

摘要

PURPOSE: To provide a tire pneumatic pressure monitoring device capable of easily taking out various data such as pneumatic pressure data to the outside. CONSTITUTION: The tire pneumatic pressure monitoring device includes a plurality of transmitters 3 provided on the tires 2 of a vehicle 1 and a receiver 4 provided on the body of the vehicle 1. Each transmitter 3 wirelessly transmits data about the internal pneumatic pressure of the corresponding tire 2. The receiver 4 wirelessly receives the data transmitted from each transmitter 3. The receiver 4 causes the data received to be displayed on a display 23 and stored in a nonvolatile memory 25. When wirelessly receiving a transmit request signal from a predetermined external communication device 5, the receiver 4 wirelessly transmits the data stored in the nonvolatile memory 25 to the external communication device 5. Thus, various data such as pneumatic pressure data can be easily taken out from the receiver 4 to the external communication device 5.
