Title:
TIRE AIR PRESSURE MONITORING SYSTEM AND DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2017222300
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire air pressure monitoring system and detection devices for enabling a monitoring device to more surely receive air pressure signals of a plurality of tires by effectively preventing the air pressure signals from being interfered by being simultaneously transmitted from a plurality of detection devices.SOLUTION: The tire air pressure monitoring system includes: a plurality of detection devices 2 respectively provided in a plurality of tires 3 of a vehicle C to detect air pressures of tires 3, transmitting air pressure signals showing the detected air pressures by radio; and a monitoring device 1 for receiving the air pressure signals, and monitoring the air pressures of the plurality of tires 3. Each detection device 2 includes: a storage part for storing transmission timing of an air pressure signal different in each detection device 2 with a specific time point as reference; a portable machine signal reception part for receiving a signal transmitted from a portable machine 6 for locking/unlocking of a vehicle door; and an air pressure signal transmission part for transmitting an air pressure signal at the transmission timing stored by the storage part with a time point when the portable machine reception part receives a signal as reference.SELECTED DRAWING: Figure 1
