Automatic detection of automotive Tire Pressure and the design of portable air supply device
Abstract
Auto high speed, flat tire is one of the major traffic accidents caused by malignancy. Non-normal atmospheric pressure tires, especially for long periods under low air pressure caused by a puncture at high speed is the most important reason. Therefore, changes in real-time monitoring of tire pressure, keeping the car under a standard tire pressure driving is the key to prevent puncture. Tire Pressure Monitoring System (TPMS) is the main role in driving the vehicle when the tire pressure on the real-time automatic monitoring of tire pressure to report low leakage and general, is drivers, passengers, protection of life and safety of early warning systems . Install tire pressure monitoring system (TPMS) can effectively prevent the tire pressure for long hours in the non-normal traffic, improve vehicle active safety. This design includes TPMS tire pressure monitoring system that analyzes the design and the design of portable pneumatic pump.
This paper analyzes the direct type and indirect TPMS advantages and disadvantages, summarized the development trend of TPMS; through the puncture factors and conditions detailed analysis, the main factors causing a puncture; design of a tire pressure monitoring system as a whole, determine the The general framework of the system, man-machine interface, tire installation and major components module choice; and in accordance with the detailed design of the overall design of a direct-type tire pressure monitoring systems, and portable tire air supply device.
