Description
Technical field
The present invention relates to a kind of product performance test device, particularly the proving installation of a kind of test setting TPMS in automobile tire.
Background technology
System for monitoring pressure in tyre (TPMS), English Tire Pressure Monitor System.It effect be, in vehicle traveling process, real-time automatic monitoring is carried out to tire pressure, and to have a flat tire and infrabar is reported to the police, to guarantee traffic safety.
At present, system for monitoring pressure in tyre is mainly divided into two types:
One is indirect type (Wheel-Speed Based TPMS, be called for short WSB), and this system is the rotating speed difference coming between comparative tire by the wheel speed sensors of automobile ABS system, to reach the object of monitoring tire pressure.ABS determines wheel whether locking by wheel speed sensors, thus determines whether start anti-lock braking system.When tire pressure reduces, the weight of vehicle can make diameter of tyres diminish, and this will cause the speed of a motor vehicle to change, and namely this change can be used for alert trigger system and give a warning to driver.
Another kind is direct-type (Pressure-Sensor Based TPMS, be called for short PSB), this system utilizes to be arranged on the air pressure that tire directly measured by each pressure transducer of taking turns tyre cavity, utilize wireless launcher pressure information to be sent to system central receiver module from inside tires, then each tire pressure information is shown.When tire pressure is too low or leak gas, system can automatic alarm.
As shown in Figure 1, it is the fundamental diagram of a kind of use direct-type TPMS widely, this TPMS is provided with sensor 5 in four tires 01, the real time data detected is sent to automobile controller by radio communication system by the air pressure in real-time detection tire, in the controller 04 that the signal sent by high frequency antenna 03 receiving sensor 5 outside tire is transferred to automobile in CAN 02, the data detected are processed, when the pressure abnormity in certain tire being detected, driver is prompted to by verbal cue or alternate manner, allow driver eliminate potential faults and ensure traffic safety.
