<p>A Bluetooth-based tire state detecting device comprises a pressure sensor (55), a temperature sensor (51), an acceleration sensor (58), a control module (60), a Bluetooth module (40), an antenna module (20) and a battery (30). The pressure sensor (55) and the temperature sensor (51) are used for detecting the pressure and temperature of tires and generating a corresponding tire state signal; the control module (60) is used for transmitting the tire state signal to the Bluetooth module (40); the Bluetooth module (40) is used for emitting the tire state signal via the antenna module (20); the battery (30) is used for powering the tire state detecting device; the acceleration sensor (58) is used for detecting automobile acceleration and sending a corresponding acceleration detection signal; the control module (60) starts the Bluetooth module (40) when receiving the acceleration detection signal; and the control module (60) controls the Bluetooth module (40) to enter a power-saving working state when not receiving the acceleration detection signal. The tire state detecting device can reliably and safely send the tire state signal via the Bluetooth module (40) and the antenna module (20), the battery (30) is long in service life, and also, energy is saved.</p> |
