The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to the scope that embodiment represents.
embodiment:
A kind of device for monitoring tyre pressure, formed by the processing terminal that is arranged on the tire pressure detecting device in 4 tires of automobile and 1 spare tire and be arranged in car, described tire pressure detecting device and described processing terminal communicate by wireless signal, described tire pressure detecting device comprises: for detection of the tyre pressure sensor of tyre temperature and pressure, the pressure change sensor of the noise producing during for detection of vehicle launch, for receiving the low-frequency coil of external low frequency energizing signal, MCU controller, HF transmitter and power unit, described tyre pressure sensor, pressure change sensor, low-frequency coil is connected with MCU controller and carries out data exchange, power unit respectively with tyre pressure sensor, pressure change sensor, low-frequency coil, MCU controller is connected with HF transmitter, described each tyre pressure sensor, pressure change sensor and HF transmitter are all provided with separately independently sequence number.In spare tire, be also provided with the acceleration pick-up for waking the tyre pressure sensor work in spare tire up.
Processing terminal comprises high-frequency receiver, MCU controller, data memory, audio alarm, button, display section and power unit, described high-frequency receiver is connected with MCU controller, MCU controller respectively with audio alarm, display section is connected, power unit respectively with high-frequency receiver, MCU controller, data memory is connected, be used for storing tyre pressure sensor, pressure change sensor, the data memory of the comparative result that in HF transmitter, the pressure and temperature of sequence number and tire compares with predefined threshold value is connected with MCU controller, button is connected with MCU controller.Pressure change sensor is connected with HF transmitter.Audio alarm is external loud speaker, and for according to alarm command, the pressure to the tire corresponding with described sequence number and/or spare tire and/or temperature occur that abnormal condition report to the police; Described display section is light-emitting diode display, the comparative result comparing for the pressure of display of tyre and/or spare tire and/or the pressure of temperature and sequence number and tire and/or spare tire and/or temperature and predefined threshold value.Power unit is the lithium cell of 3V.MCU controller adopts PIC12F617 micro controller system.
When device work, be arranged on the data that tyre pressure sensor, pressure change sensor and HF transmitter in each motor tire are responsible for data acquisition and are launched the various states of tire, tyre pressure sensor will detect gaseous tension and the tyre temperature of each tire current time, these data pass to HF transmitter after will being processed by MCU controller, HF transmitter, again by after Data Modulation, is transmitted to and is arranged on high-frequency receiver in compartment with radio frequency signal.High-frequency receiver receives after radio frequency signal, is demodulated into the binary code that MCU controller can be identified, then shows on read-out by MCU controller.If data exceed alarm threshold arrange alert data, annunciator can toot cry; If do not exceed the alert data of alarm threshold setting, system keeps this " normal mode " and shows, and can the state of button adjustment demonstration or the content (temperature or pressure) of selection demonstration.
Reach maximum in order to extend the service life of battery and make it, once not need tire to carry out continuous detection (generally the vehicle stop in the situation that, while stopping especially for a long time), wish to reduce the duplicate measurements number of times of given interval as far as possible.Conventionally, in the time of vehicle stop, just do not sound or sound size is 0 substantially, pressure change sensor can detect this state, so, processing terminal starts " economy " pattern, and its measuring intervals of TIME is substantially than the length of mode standard, as 2,3, the time gap of 5,30,60,120min.This operational mode especially can be saved battery; In the time that vehicle launch travels, pressure change sensor can detect this state, so processing terminal starts " normally " pattern, its measuring intervals of TIME recovers mode standard.
Device for monitoring tyre pressure of the present utility model, has increased the tire pressure detecting device in spare tyre, and adopts acceleration pick-up control triggering tire pressure detecting device to carry out work.Temperature in spare tyre, pressure after tested, are sent to processing terminal, inform navigating mate by LCD display with form intuitively, and safer driving environment is provided.
The tire pressure detecting device using in spare tyre, under normal circumstances in park mode, acceleration signal detected or receive after the specific extraneous signal that system for detecting tire pressure handheld tool sends at acceleration pick-up, wake tire pressure detecting device up and carry out work, make it to carry out work with the pattern of economize on electricity as far as possible.Conventionally stepney in traverse or place state vertically, under these two kinds of laying states, accelerates to advance in process at automobile, and acceleration pick-up can collect acceleration signal, and triggers that tire pressure detecting device detects, signal transmission work.Tire pressure detecting device is after work, be certainly advanced into the forced dormancy pattern of long period (being generally 24h) by the software setting carrying, to save power supply, after this forced dormancy pattern finishes, module is still in park mode, until acceleration pick-up detects acceleration signal again, and wake tire pressure detecting device work up.Input pre-determined signal specific at system for detecting tire pressure handheld tool, or acceleration pick-up in tire pressure detecting device detect acceleration/accel reach a certain prior preset value above after, tire pressure detecting device departs from forced dormancy pattern voluntarily, and enter mode of operation, and identical with the tire pressure detecting device mode of operation in other tires.Make in this way, can be in the situation that saving use tire pressure detecting device internal cell electric weight, make it to carry out work in needs, and can be in the situation that not needing to use external instrument, after spare tyre is replaced on car, automatically enter mode of operation, and stop the forced dormancy pattern of tire pressure detecting device in spare tyre, to guarantee the safe maneuverability of vehicle.
The information of spare tyre can effectively be controlled and manage to the utility model, while guaranteeing that vehicle has used tire to encounter unforeseen circumstances when driving, has intact spare tyre to use, and avoids using unsafe spare tyre; And mode of operation can automatically switch by handheld tool or by the acceleration/accel detecting, the in the situation that of economize on electricity, facilitate chaufeur to use, can extend the service life of tire pressure detecting device in spare tyre, there is certain economy and safety.
Here description of the present utility model and application is illustrative, not wants scope of the present utility model to limit in the above-described embodiments.Here the distortion of disclosed embodiment and change is possible, and for those those of ordinary skill in the art, the various parts of the replacement of embodiment and equivalence are known.Those skilled in the art are noted that in the situation that not departing from spirit of the present utility model or essential characteristic, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.In the situation that not departing from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
