Description
Valve inside integrated transducer tyre pressure monitor of the present invention belongs to technical field of automotive electronics, is specifically related to a kind of security personnel's instrument that is installed in the tire tire tube valve with the incorporate baroceptor monitoring car of valve inside air pressure.
Inflation tyre invention century more than one, normally whether the inflation pressure of tire, determining the life-span and the traffic safety of tire, how real-time air pressure in the tire that flies to change is monitored and is monitored, so far the monitoring and the display instrument instrument that do not have tyre pressure in the operator's compartment are so the explosion-proof and gas leakage of tire and the traffic safety problem of bringing thus are still unsolved difficult problems.Have the problem of following aspect at present:
1. Tyre inflating pressure method of inspection easily not, so tyre pressure or high or low, inflation pressure is nonstandard, reduces tire travelled distance and tire service life;
2. inflation pressure superpressure or under-voltagely cause car load machinery premature wear and influence consumption of fuel, oil consumption may increase 10--15%, also can potential many hidden dangers;
In the vehicle ' tire gas leakage to cause and rub that tire, friction generate heat, blow out etc. be the reason of tire infantile failure and common damage;
4. according to traffic department statistics, 3% traffic accident is arranged because of initiations of blowing out of tyre pressure superpressure in the vehicle operating, blow out as truck of nineteen ninety-five express highway and caused 28 cars collisions, the accident of the casualties of people more than 20; The accident that occurs on another express highway is that the driver did not know after tire was rubbed in its trailer gas leakage, continues again two kilometers and causes the road surface to scratch damage for big section;
More than its problem, differ and enumerate.Be to solve the Tyre inflating safety problem, countries in the world are all at research tyre pressure monitoring device in recent years, yet because the work under bad environment of tire is again a rolling-operation, and the installation position is narrow and small or the like, and monitoring brings many difficulties to tyre pressure.What it is reported the research at present of U.S. a company is radio telemetry tyre pressure device, what Germany a company was studied is pulse measuring pressure tire warning device, the patented technology of China's bulletin mostly is to adopt radio monitoring tyre pressure device, combine opinion these prior aries both domestic and external, monitoring device comprises that monitoring sensor and radiating portion are installed on the wheel of high speed revolution, hinder the balance movement under the wheel high speed revolution, the power supply of circuit or powerup issue are difficult to resolve and determine on the wheel, sensor is contained in tire tire tube valve place and not only brings the inconvenience of inflating, and wheel time mud is paddled, more to cross the bank rapid wear perishable for ditch, wheel is a lot of on the car in addition, take turns truck as ten and attract the crowded of installation with going up monitoring device of each installation of the numerous wheel of trailer again, the disorder of monitoring etc. also is a problem, most of in addition wireless monitor device complex structures, member is many, the cost height, as used pressure sensor price height, life-span is short, the pressure sensor 0--1Mpa of external a company need 100 yuan of Renminbi/, domestic pressure sensor 0--1Mpa need 200--300 unit/and can only be with 3--4 time or the like.The existing tyre pressure monitor of these problem definitions also has such or such deficiency or problem apart from practical stage.New in sum invention should make every effort to overcome above-mentioned deficiency and shortcoming.
