Abstract
The invention relates to the field of automotive electronics, in particular to a tire pressure monitor system (TPMS). The TPMS has the structure that tire pressure sensors are arranged on tires of a vehicle; data, which is detected by the tire pressure sensors on the tires, is transmitted to a receiver in a wireless communication manner so as to cause a driver to monitor states of the tires; a plurality of triggers achieve the operation of the ID self judgment of an automatic positioning sensor in self-checking, sensor replacing or tire rotation of an ignition sensor; and a display terminal displays the tire parameter information. The tire pressure sensor can automatically judge whether the vehicle is in a driving state or not, automatically adjust the acquired data and the transmit period, and sets the transmitting conditions such as pressure change, quick gas leakage and the like. The tire pressure monitor system provided by the invention not only ensures the real-time performance of displayed data on a display system, but also saves electric quantity to the great extent; and moreover, the service life can be ensured for 8 to 10 years through match with a high-capacity lithium battery.
Description
Technical field
The present invention relates to vehicle electric field, specifically relate to a kind of TPMS system for monitoring pressure in tyre.
Background technology
Automobile tire pressure monitoring system mainly is that high-precision sensor real-time tire pressure and temperature are detected automatically when vehicle ' is installed in motor tire; And be transferred in the operator's compartment through wireless radio frequency mode; Tell chaufeur to work as the accurate force value of front tyre through modes such as literal, sound, alarm lamps; And can oneself's judgement carry out tire pressure, the too high or too low for temperature warning, be used for pointing out chaufeur tire pressure mal, with guarantee driving safety.
Summary of the invention
To the technical matters that exists in the prior art, the object of the present invention is to provide a kind of TPMS system for monitoring pressure in tyre of superior performance.
The technical scheme that the present invention adopts is following:
The TPMS system for monitoring pressure in tyre; On car two each tires tyre pressure sensor is set, the data that each pressure of tire sensor is detected is sent to receptor, supply the driver to monitor the state of each tire through wireless communication mode; It is characterized in that said monitoring system also includes:
A plurality of binary pairs are realized ignition detector self check, the operation that more self-orientation sensor ID oneself judges when emat sensor or interchanging of tires;
And display terminal, the display of tyre parameter information.
Further, said binary pair is connected with receptor through the LIN net, and transfers to tyre pressure sensor through low frequency 125KHz signal.
Further, the integrated tire pressure of said tyre pressure sensor, tire gas temperature, tyre rotation centripetal force detection module, and through the 3V lithium battery power supply.
Further, the integrated MCU module of said receptor, built-in radio frequency is reconciled module, audible alarm module, power module and earthing module.
Further, said display terminal comprises display system, integrated three charactrons of said display system and position indication LED lamp.
TPMS system for monitoring pressure in tyre of the present invention, its beneficial effect is:
1, tyre pressure sensor can judge independently whether vehicle is in motoring condition, and oneself's adjustment image data and transmission cycle, has set like pressure to change, and gas leakage waits the transmission condition fast.Both guaranteed the real-time of display data on the display system, maximum save power cooperates a high-capacity lithium battery can guarantee the service life in 8 to 10 years again.
2, the built-in tire pressure sensor has the stem of valve of angle adjustable, can be fit to the wheel hub installation requirement of most of vehicle.
3, designed the tyre pressure sensor of 450kpa, 700kpa, three kinds of ranges of 1400kpa, applicable different classes of car, truck, passenger vehicle, and satisfy in the laws and regulations requirement to the pressure acquisition precision.
4, set like the alarm mode under the conditions such as high pressure, low pressure, gas leakage, high temperature, comprised various abnormal condition that tire possibly occur and through mode actvies such as sound, light prompting navigating mates.
5, two kinds of sensor ID matching methods have been simplified the operation of user to this process as much as possible.

The specific embodiment
Shown in Fig. 1-5; The TPMS system for monitoring pressure in tyre is provided with tyre pressure sensor on car two each tires, through wireless communication mode the data that each pressure of tire sensor is detected is sent to receptor; Supply the driver to monitor the state of each tire; Simultaneously, also comprise by a plurality of binary pairs, and display terminal (also can be integrated on the receptor).
A plurality of binary pairs, binary pair is connected with receptor through the LIN net, and transfers to tyre pressure sensor through low frequency 125KHz signal.Realize ignition detector self check, the operation that more self-orientation sensor ID oneself judges when emat sensor or interchanging of tires.
Receptor can send out low frequency signal through binary pair and send order to tyre pressure sensor; Receptor and tyre pressure sensor can reach the purpose of a two way communication through binary pair like this; Improved the alerting ability of total system, can realize some as system light a fire self check, automatically intelligence operations such as sensor ID are set.
The integrated tire pressure of tyre pressure sensor, tire gas temperature, tyre rotation centripetal force detection module, and through the 3V lithium battery power supply.
Tyre pressure sensor is isolated rugged environment in the tire, is installed on the tire wheel hub through tire tube valve through modes such as encapsulatings.
Centripetal acceleration when the interior gas temperature value of relative barometric pressure value, motor tire in the logical measured automobiles tire of tyre pressure sensor, automobile rotation.Simultaneously; Have integrated microprocessor oneself and judge that work at present pattern and radio frequency send condition, have and comprise the low frequency receptor; Have and be used for triggering, test and change mode sensor, have and comprise a radio frequency sending set, be used to transmit tire information to receptor.
Tyre pressure sensor passes through lithium battery power supply; Can judge the running state that current vehicle is positioned through sampling centripetal acceleration value; And, different acquired signal cycle and data transmitting period being arranged under different patterns according to the self-operational mode of adjusting of the running state of vehicle, this function has guaranteed that vehicle is in when going attitude; The real-time of tire data can guarantee again to be at vehicle and reduce battery consumption when stopping attitude as far as possible.
The integrated MCU module of receptor, built-in radio frequency is reconciled module, audible alarm module, power module and earthing module.
Receive the radiofrequency signal that controller function is sent for the reception tyre pressure sensor, and these tire pressure data and predefined data are done comparison, judged whether abnormal tyre pressure, and these information are transmitted display system, inform chaufeur current vehicle tire pressure state.
Display terminal comprises display system, display of tyre parameter information, integrated three charactrons of display system and position indication LED lamp.Display system is the interactive interface of TPMS system and navigating mate, can inform chaufeur vehicle tyre current states and concrete data, and the warning of the modes such as light of when the abnormal tyre pressure or the system failure, sounding.
