Tire pressure information acquisition equipment and operation system thereof

Abstract

The invention relates to the technical field of tire pressure detection, and discloses tire pressure information acquisition equipment and an operation system thereof, the tire pressure is monitored by adopting a mode of combining a direct method and an indirect method, so that the measurement failure of a tire pressure monitor caused by factors such as high temperature can be avoided, and the measurement failure caused by factors such as high temperature can also be prevented; and furthermore in an indirect measurement method, the condition that the tire pressure of a plurality of tires is abnormal at the same time and cannot be known by a wheel speed sensor is avoided, the monitoring precision is improved, the safety of vehicle driving is improved, a temperature sensor and the like are arranged, a piston is matched with an air inlet pipe for continuous air inlet, the air pressure in the tires is reduced in a self-adaptive mode, and the tire burst phenomenon caused by too high tire pressure is avoided; through arranging an exhaust electromagnetic valve and the like, the highly-compressed gas in the gas storage pipe barrel is gradually exhausted into the tire through the exhaust pipe, so that the tire pressure of the tire in the corresponding low-temperature environment is increased in a self-adaptive manner, the phenomena of driving comfort weakening and the like caused by insufficient tire pressure in the low-temperature environment are avoided, and the safety of a vehicle in the driving process is further improved.

Description

technical field [0001] The invention relates to the technical field of tire pressure detection, in particular to a tire pressure information collection device and an operating system thereof. Background technique [0002] The direct tire pressure monitoring system uses the pressure sensor installed in each tire to directly measure the tire pressure, and displays and monitors the tire pressure. When the tire pressure is too low or there is leakage, the system will automatically alarm; indirect The type tire pressure monitoring system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between the tires to achieve the purpose of monitoring the tire pressure. The main disadvantages of this type of system are: 1. It cannot display the accurate instantaneous Air pressure value; 2. When the same axle or wheel on the same side or all tire pressures drop at the same time, the alarm cannot be given; 3. Factors such as vehicle speed and detection a...
