Description
Technical field
The present invention relates to the monitoring automobile tyre pressure technology, what be specifically related to is a kind of system and method for realizing general TPMS launch terminal upgrading that connects based on wire communication.
Background technology
At present, system for monitoring pressure in tyre mainly is divided into two types: a kind of is indirect type (Wheel-Speed Based TPMS, be called for short WSB), this system is that the wheel speed sensors by automobile ABS system comes the rotating speed difference between the comparative tire, to reach the purpose of monitoring tire pressure.ABS determines whether locking of wheel by wheel speed sensors, thereby determines whether to start antiblock device.When tire pressure reduced, the weight of vehicle can make diameter of tyres diminish, and this will cause the speed of a motor vehicle to change, and this variation namely can be used for triggering warning system and gives a warning to the driver, belongs to afterwards passive-type; Another kind is direct-type (Pressure-Sensor Based TPMS, be called for short PSB), this system utilizes to be installed in the air pressure that each pressure sensor of taking turns tyre cavity is directly measured tire, utilize wireless launcher that the information such as pressure, temperature are sent to system on the central receiver module from inside tires, then each vehicle tyre barometric information is shown, in too low or when gas leakage when tire pressure, system can automatic alarm, belongs in advance Initiative Defense.
A built-in sensors is installed by the tire dice at tire by direct-type TPMS system, the bridge type electron gas pressure sensitivity that comprises induction air pressure in the sensor should be installed, it is converted to electric signal with air pressure signal, by wireless launcher signal is emitted, to realize under driving or static state, the pressure of real time monitoring tire, the data such as temperature, and be transmitted into receptor by wireless mode, in the telltale various data variation of demonstration or with forms such as buzzings, remind the motorist, and change at tire flat and pressure and to surpass Secure Threshold (this threshold value can be set by telltale) time and report to the police, with guarantee driving safety.Because immediate system can be measured at any time the actual wink of each inside tires and press, and is easy to determine the fault tire, has the high characteristics of accuracy rate, therefore uses comparatively extensive.
The TPMS system mainly adopts 315MHz/433MHz, the modulation system of ASK and FSK in the automobile that each car production manufacturer of Present Global produces.Because the communication frame format of each TPMS system of auto vendor is difference to some extent, the launch terminal of TPMS has more than tens kinds with regard to causing on the market like this, and each other can not be compatible, if the TPMS launch terminal that is installed in the motor tire damages, just must change same brand or of a sort launch terminal, otherwise can't use, and will cause like this user's replacement cost to increase.
