From the Provincial Public Security Department information obtained, we began a vehicle tires explosion-proof early-warning device of the development work. Along with our country road traffic the rapid development of, traffic accidents increasingly becoming up a more and more serious social problem. Particularly yes on the highway of vehicles, due to a puncture while the causing the accident increasing daily. Of such accidents has the instantaneous Xing, chain Xing, have done great harm, but also cause for very hard to detect, it gives the people's lives and property brought a huge losses. After investigation studies show that, if in the automobile guide wheel flat tire before the, able to predict out the dangerous run's signal, and in a timely manner alarm to enable motorists drivers to take measures, such as deceleration sail to slow lane, parking inspection, etc.. Then be avoided accident from occurring. On the highway, automobile guide wheel flat tire yes lead to traffic accidents one of the main. This paper research's is the automobile guide wheel flat tire of the early warning device, order to accurately's acquisition tire deformation signals, Wen middle in order to vehicle tires as the research object, detailed analysis of the tire and road surface process of interaction. Of tire deformation on process and the vehicle tires the force on different forms of. In the on the tires deformation, affected by force With the detailed studies on the basis of, Wen middle explores the caused by the wheels a puncture the reasons for, and the explosion-proof scheme's adopt conducted a comparison and screening. We chose the latest successful development of new type of sensitive Material - sense of pressure conductive rubber, referred to as conductive rubber. The Material both the genus rubber elastic simultaneously but also a good electrical conductivity, is the feelings of tire compression, thermal deformation's core components. We of the of conductive rubber elastic modulus well as resistors ratio conducted were measured, and come to the relevant conclusions. Subsequently pairs of how to utilize conductive rubber to go to take tire deformation's correlation signal conducted a specific design, and made schematics. Design results able within the, the tire casing pressure deformation-sensitive is converted to resistance changes, and through the sensing means is converted to voltage changes, completed the the signal take the job that. Then conducted a overall program in the design and explore the, in order to conductive rubber change in resistance was sense of pressure signal to take the source of, set up a signal oscillations transmitting, the signal receiving of specific programs, and the line's Model No. anti-Interference and signal recording made a correlation expounded. The early-warning device the realization of, will greatly reduce the puncture accident the occurrence of, the benefit of society, Wen middle simultaneously of this early-warning device application prospects made a prospected.
