Abstract
The invention discloses a method of positioning tire pressure sensors in an automobile tire air pressure monitoring system. After being powered on to work, a receiver host machine wakens all tire pressure sensors through drive information containing random numbers sent by low-frequency antennas sequentially, and the corresponding tire pressure sensors are wakened to detect the temperatures and the pressures of tires and then send the detected tire information and random numbers to the receiver host machine through high-frequency antennas; and after receiving the high-frequency information sent by the tire pressure sensors, the receiver host machine compares the sent random numbers with the received random numbers, and if the sent random numbers are identical with the received random numbers, the received data are identified valid and the mounting positions of the tires equipped with the tire pressure sensors on an automobile are determined. By the method, data received by the receiver host machine can be confirmed effectively, and the tires equipped with the tire pressure sensors can be accurately positioned.
Description
Technical field
The present invention relates to technical field of automotive electronics, particularly relate to a kind of air pressure of automobile tire monitoring system guarantees the accurate location of tire through the affirmation of random number method.
Background technology
At present; Communication between the reception main frame of most air pressure of automobile tire monitoring system and the tire pressure sensor (being tyre pressure sensor); Drive through low-frequency antenna for simple, the mode that wait time receives, tire pressure sensor emission data do not obtain actv. and confirm; There is certain potential safety hazard, therefore might causes and fail to report alert or flase alarm.
Summary of the invention
The technical matters that the present invention will solve provides the method for tyre pressure sensor location in a kind of air pressure of automobile tire monitoring system, guarantees that the data that receiver host receives obtain the actv. affirmation, accurately locate the position of tyre pressure sensor place tire.
For solving the problems of the technologies described above, the method for tyre pressure sensor location comprises the steps: in the air pressure of automobile tire monitoring system of the present invention
Send the activation bit that comprises random number through low-frequency antenna successively after receiver host works on power and wake each tyre pressure sensor up; Corresponding tyre pressure sensor is waken up temperature, the pressure that tire is detected in the back, and the information and the random number that detect are wirelessly sent to receiver host through high frequency antenna; After receiver host receives the high-frequency information of tyre pressure sensor emission; The comparison random number; Confirm that the data that receive are effective when the random number of sending when tyre pressure sensor is consistent with the random number of reception, and the installation site of tire on this vehicle of definite this tyre pressure sensor of installation.
Method of the present invention has guaranteed tyre pressure sensor and has received communicate by letter between the main frame safe, effective, thereby realized the accurate location of tyre pressure sensor place tire owing to adopt the communication modes of random number affirmation, reduced potential safety hazard.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Accompanying drawing is method one an embodiment control flow scheme drawing of the present invention.
The specific embodiment
Receiver host after working on power, is responsible for calling random number functions and is produced random number and add low-frequency coil to and send in the data and send with activation bit.Also be responsible for the information that receives is handled, think if the random number of the random number that receives and emission is consistent to receive data, otherwise give up for effective.Whether the tyre pressure sensor ID that compares reception for valid data again is consistent with the tyre pressure sensor ID (identification number) of the correspondence position that receiver host is preserved, if unanimity judges whether the pressure of tire, temperature is normal again; If inconsistent, then need mode through the secondary comparison determine whether that the situation of emat sensor more or exchange tire takes place.
Shown in accompanying drawing, each tire is associated with the uniquely identified tyre pressure sensor, and a plurality of tyre pressure sensors are arranged at respectively in each tire.
Said tyre pressure sensor comprises pressure, temperature and acceleration pick-up and high-frequency emission module; Be used for monitoring in real time the information such as pressure, temperature and acceleration/accel of tire; After receiving the activation bit and random number of low-frequency antenna transmission; Information such as the pressure of the motor tire of gathering, temperature and random number through integrated wireless transmitting terminals, are carried out high-frequency emission.
Low-frequency antenna is positioned near each tire, can scope wake each tyre pressure sensor successively separately up in the actv. near region.Low-frequency antenna is connected with receiver host, is used for drive signal and the random number information that the reception main frame sends over are carried out the low frequency wireless transmission.
After receiver host works on power, be responsible for calling rand () random number functions,, send to low-frequency antenna with activation bit to be used for producing random number and to add low-frequency coil to and send in the data.Receiver host is responsible for the information that receives is handled, and thinks if the random number of the random number that receives and emission is consistent to receive data for effective, otherwise gives up.Whether the tyre pressure sensor ID that compares reception for valid data again is consistent with the tyre pressure sensor ID of the correspondence position that receives the main frame preservation; If it is consistent; Whether pressure, the temperature of judging tire again be normal, if the pressure of tire and/or temperature value are in abnormal ranges, and output alarm information then; If inconsistent, then need the situation that determines whether that the replacing tyre pressure sensor took place or exchange tire through the mode that secondary is compared.
If the random number that receives for the second time is correct and tyre pressure sensor ID is consistent with last time, the tyre pressure sensor ID that receives is kept at overrides original this tyre pressure sensor ID among the cooresponding EEPROM, and the information that receives is handled.
Receiver host can show (IPK demonstration) warning message of being correlated with by instrument.
More than through the specific embodiment the present invention has been carried out detailed explanation, but these are not to be construed as limiting the invention.Under the situation that does not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be regarded as protection scope of the present invention.
