Title:
AIR PRESSURE OBSERVATION SYSTEM AND TIRE AIR PRESSURE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/148039
Kind Code:
A1
Abstract:
Provided are an air pressure observation system with which it is possible to detect the air pressure of a tire when a vehicle is parked, and a tire air pressure detection device for detecting the air pressure of a tire. The detection device is provided with a sensor unit for sensing movement of a tire, a control unit for controlling a detection unit so as to detect air pressure with each passing of a prescribed first cycle during a first state in which movement is not sensed by the sensor unit, and a transmission unit for transmitting the detection value detected by the detection unit to an observation device. The observation device is provided with a reception unit for receiving the detection value, and a storage unit for storing the detection value received by the reception unit.
