Abstract

The invention relates to an automobile tire pressure monitoring system which adopts the Bluetooth technology, in particular to a low-power consumption tire pressure monitoring system of a large vehicle with the number of tires more than eight, comprising a sensor module and a Bluetooth transmitter module which are arranged in each automobile tire and a Bluetooth receiving module which is arranged on an automobile bridge. The pressure monitoring system has the advantages that as frequency domain extension of the Bluetooth is operated, the sensor in each tire can accurately communicate with a receiver on the automobile bridge, thus avoiding the mutual interference of the sensors of all the tires and the interference of the tire pressure sensors of the adjacent automobiles; and a master micro-network and a slave micro-network of small range of the Bluetooth also can carry out topological extension, thus being easy to establish a plurality of tire pressure monitoring systems.

Description

technical field

[0001] The invention relates to an automobile tire pressure monitoring system using bluetooth technology, in particular to a tire pressure monitoring system with low power consumption for large vehicles with more than eight tires. Background technique

[0002] The car tire pressure monitoring system (TPMS) is mainly used to automatically monitor the tire pressure in real time when the car is running, and to give an alarm to the tire leak and low pressure to ensure driving safety, which is the life safety guarantee for drivers and passengers early warning system. During the high-speed driving of a car, tire failure is the most worrying and difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. According to statistics, 70%-80% of the traffic accidents on the expressway are caused by blown tires. Keeping the standard tire pressure for driving and finding the tire leaks in time are the key to prevent blown tires, a...
