Description
Technical field
The utility model relates to a kind of automotive tyre pressure monitoring device, a kind of specifically tire pressure monitoring device based on the centripetal force switch.
Background technology
In the galloping process, tire fault is the major reason that sudden traffic accident takes place.According to statistics, have 70% to cause in the traffic accident that on express highway, takes place approximately by blowing out.And the tyre pressure that maintains the standard travels and in time find that tire gas leakage is to prevent the key of blowing out, and is a kind of important leverage to safe driving to automotive tire pressure, the isoparametric supervision of temperature therefore.R and D automotive tire pressure supervisory system is to guarantee the effective technology measure of traffic safety, also is the important topic that currency must be studied.
Current tire pressure monitoring method mainly contains following several, the one, utilize the sensing function of existing ABS system to come the rotating cycle of comparative tire, the circumference of the tire of tire pressure deficiency can shorten, so if words of certain pressure of tire deficiency, rotating cycle just can be different with other tire when travelling, but the monitoring system accuracy of this mode and reliability are not high, and especially system will lose efficacy when four pressure of tire are equally low; The 2nd, utilize to be installed in the air pressure that each pressure sensor of taking turns tyre cavity is directly measured tire, radio-frequency signal generator is equipped with in each wheel rim tire tube valve inboard, receptor is housed in the mudwing, utilize wireless launcher that pressure information is sent to system on the central receiver module from inside tires, then each tire pressure data is shown, in too low or when gas leakage when tire pressure, system can auto alarm; The 3rd, a kind of tire pressure monitoring system that is named as TPMS, TPMS is present most popular vehicle tire pressure supervisory system, it can be in real time under motoring condition, dynamically tire pressure and temperature are monitored automatically,, gas leakage low excessively, too high to tire pressure and temperature are crossed high strange phenomena and are carried out auto alarm, with the incidence of minimizing accident, guarantee traffic safety.Say that from system construction information such as pressure, temperature can send reception by wireless device.And this TPMS is indirect TPMS, and indirectly TPMS does not have pressure sensor, needs to rely on the intrasystem speed sensor of ABS to detect different with the comparative tire rotating speed.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, a kind of tire pressure monitoring device based on the centripetal force switch is proposed, can be applicable to multiple vehicle, the parameters such as pressure and temperature of monitoring tire, has more high sensitivity, and can realize that zero velocity is measured and detection many tire flats situation the time, save power consumption simultaneously.
The technical scheme that the utility model solves above technical matters is:
Based on the tire pressure monitoring device of centripetal force switch, comprise being located at the master control system in the car and being located at the interior wireless monitor transceiver module of each tire, carry out radio communication between master control system and the wireless monitor transceiver module; Master control system is made up of treater, RF radiofrequency signal receive-transmit system, display system, speech prompting system and man-machine exchange I/O mouth, RF radiofrequency signal receive-transmit system and treater join, the output of treater connects display system and speech prompting system, and the output of man-machine exchange I/O mouth connects treater; The wireless monitor transceiver module is made up of treater, RF radiofrequency signal receive-transmit system, centripetal force switch, tire pressure sensor and temperature sensor, the output of centripetal force switch, tire pressure sensor and temperature sensor connects treater, and the output of treater connects RF radiofrequency signal receive-transmit system.
Carrying out geocoding by Modbus communication protocol between master control system and the wireless monitor transceiver module communicates by letter.The wireless monitor transceiver module is fixed on the wheel hub, is powered by button cell.
The wireless monitor transceiver module can obtain the main state parameter of tire by pressure sensor and temperature sensor, is transferred to master control system by the RF radio-frequency system then, master control system display of tyre parameter and send voice suggestion, warning.Because the wireless monitor transceiver module is imbedded at inside tires, and be in the real time operation state, so just need very to pay attention to reducing its power consumption, prolong its battery life, reduce the replacing of battery, utilize the centripetal force on-off signal as differentiating the signal of interest whether automobile is in motoring condition at this.If be in halted state, can make the treater of wireless monitor transceiver module and radio-frequency module enter sleep state, reduce system power dissipation to greatest extent; If being in motoring condition, automobile is in real-time monitor state as monitoring judgment signal wake up process device and radio-frequency module.
The utility model all is provided with tyre pressure sensor in each tire, these sensors are sent to information such as pressure and temperature in the central receptor by radio frequency (RF) signal, though cost is higher relatively, but there is significant performance advantage in this system, has more high sensitivity, and can realize that zero velocity is measured and detection many tire flats situation the time, save power consumption simultaneously.
Description of drawings
Fig. 1 is a connection block diagram of the present utility model.
The specific embodiment
Embodiment one
The connection of present embodiment as shown in Figure 1, a kind of tire pressure monitoring device based on the centripetal force switch, comprise that main website is the interior master control system of car one by one, several slave stations that have geocoding are the wireless monitor transceiver module in each tire, carry out radio communication between master control system and the wireless monitor transceiver module; Master control system is made up of treater, RF radiofrequency signal receive-transmit system, display system, speech prompting system and man-machine exchange I/O mouth, RF radiofrequency signal receive-transmit system and treater join, the output of treater connects display system and speech prompting system, and the output of man-machine exchange I/O mouth connects treater; The wireless monitor transceiver module is made up of treater, RF radiofrequency signal receive-transmit system, centripetal force switch, tire pressure sensor and temperature sensor, the output of centripetal force switch, tire pressure sensor and temperature sensor connects treater, and the output of treater connects RF radiofrequency signal receive-transmit system.
Wireless monitor transceiver module in the tire pressure monitoring system of the present utility model is placed on inside tires, can be fixed on the wheel hub, power by button cell, it can obtain the main state parameter of tire by pressure sensor and temperature sensor, be transferred to master control system by the RF radio-frequency system then, master control system display of tyre parameter and send voice suggestion, warning.Because the wireless monitor transceiver module is imbedded at inside tires, and be in the real time operation state, so just need very to pay attention to reducing its power consumption, prolong its battery life, reduce the replacing of battery, utilize the centripetal force on-off signal as differentiating the signal of interest whether automobile is in motoring condition at this.If be in halted state, can make the treater of wireless monitor transceiver module and radio-frequency module enter sleep state, reduce system power dissipation to greatest extent; If being in motoring condition, automobile is in real-time monitor state as monitoring judgment signal wake up process device and radio-frequency module.
