The utility model content
To the technical matters that exists in the prior art, the purpose of the utility model is to provide a kind of system for monitoring pressure in tyre of superior performance.
The technical scheme that the utility model adopts is following:
System for monitoring pressure in tyre; It is characterized in that; On each tire of vehicle tyre pressure sensor is set, through wireless communication mode the data that each pressure of tire sensor is detected is sent to receptor, said monitoring system also includes a plurality of binary pairs; 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, also comprise display terminal, said display terminal comprises display system, integrated three charactrons of display system and position indication LED lamp.
The utility model system for monitoring pressure in tyre, 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; System for monitoring pressure in tyre is provided with tyre pressure sensor on each tire of vehicle, 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).
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 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.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technical personnel in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
