Abstract
The invention discloses a realization method of a tire pressure product offline positioning system, in particular for a front loading market of vehicles. As shown in figure 1, the realization method comprises two important parts of a positioning processor and a low-frequency trigger, wherein the low-frequency trigger is mainly used for triggering a tire pressure monitoring module to emit own ID number; and the positioning processor is mainly used for collecting ID numbers of tire pressure emitting modules corresponding to the positions of tires and sending bound positioning information to a central receiving module or a BCM to finish positioning and inspection procedures after the assembly of tire pressure products.
Description
Technical field
The present invention relates to automotive electronic technology, be specifically related to the frock field of tire pressure product in automotive safety.
Background technology
Along with popularizing of automobile, automotive safety is more and more valued by the people, particularly the active monitoring equipment of some automotive safetys, and its importance is more and more come more outstanding.
Tire pressure monitoring system (TPMS), by adopting tire pressure sensing unit and the tire pressure monitoring unit of twireless radio-frequency communication, achieves the real-time monitoring to tire pressure.TPMS by installing highly sensitive sensor on each tire, under driving or static state, the data such as pressure, temperature of real time monitoring tire, and be wirelessly transmitted into receptor, show various data variation over the display or with forms such as buzzings, remind motorist.
Market is filled before automobile, today of automobile standard configuration is progressively become at tire pressure product, how before automobile rolls off the production line, tire pressure product is carried out in enormous quantities, high efficiency, automation initial alignment become of crucial importance, this just proposes harsh requirement to relevant corollary equipment.The present invention proposes, by adopting wireless communication technology, to realize the triggering of low frequency, and the data of high frequency send, and the receiving demodulation of high-frequency data realizes roll off the production line location and auxiliary detection.
Summary of the invention
Tire pressure product supporting in enormous quantities, be unable to do without relevant automatic jig equipment and replaces loaded down with trivial details artificial location, and to improve the reliability of supporting efficiency and assembling, the high efficiency realizing tire pressure product rolls off the production line positioning work.The invention discloses a kind of tire pressure product realizing the demand to roll off the production line localization method, also possess auxiliary detection function simultaneously.
The technique effect that the present invention is useful is
:
It is high that implementation method disclosed by the invention has degree of automation, and efficiency is high, high reliability.By adopting this method, the supporting efficiency rolled off the production line of tire pressure product can be improved, effectively reducing the labour intensity of workman, reduce the cost that assembling produced by car load.

Detailed description of the invention
The present invention proposes a kind of tire pressure product to roll off the production line the implementation method of position fixing system, realize from system, the hardware implementing to inner main modular all elaborates, and can provide feasible solution for the batch of tire pressure product location of rolling off the production line.
Fig. 1 is the hardware implementing block diagram of whole system, in the process that automobile rolls off the production line, first automobile is moved on to position corresponding to low-frequency trigger, PC sends the near front wheel sense command to location processor end by serial ports immediately, location processor is sent to corresponding low-frequency trigger by CAN line by detecting instruction again, this low-frequency trigger starts the low frequency wake-up data sending 125Khz immediately, be positioned at the tire pressure monitoring module of motor tire inside after receiving this low-frequency data, the ID code of oneself is sent out immediately by 434Mhz, then location processor carries out receiving demodulation to this rf data, obtain the ID code of this tire pressure module.According to identical ID code acquisition methods, each tire of automobile obtains respective ID code successively, in this process, if there is the ID code of certain tire to obtain, then system understands the low frequency triggering acquisition oneself carrying out maximum 2 times, if still cannot obtain corresponding ID code, then system can record the position of the corresponding tire of this car voluntarily, be convenient to personnel inquiry problem tire pressure module, this operation also mean to early stage tire pressure module assembling carried out on-line checkingi.After the acquisition that location processor completes ID code, can automatically all ID codes be sent in PC, the meeting of this ID code and corresponding tire are bound one by one, again the information data of having bound is sent to location processor, binding information is finally sent to central acceptance module (or BCM) by the RF signal of 434Mhz by location processor, completes the whole positioning process that rolls off the production line.
Fig. 2 is the hardware implementing block diagram of location processor, this treater directly adopts 220V electric main to power, 220V alternating-current voltage/AC voltage is sent to bridge rectifier circuit and carries out rectification after transformer pressure-reducing to 15V, carries out filtering subsequently, then the LDO being sent to 5V and 12V carries out voltage stabilizing.5V after voltage stabilizing directly supplies MCU, radiofrequency emitting module, Receiver Module, CAN module and serial port module on location processor.12V passes out to low-frequency trigger after voltage stabilizing, as power supply.Receiver Module and radio frequency sending module are all operated in 434Mhz, and carry out solution mediation to data respectively and send, the receiving sensitivity of receiver module is not less than-90dBm, and the emissive power of transmitter module is less than 5dBm.MCU is responsible for process to data herein, and the CAN communication of low-frequency trigger, and and the serial communication of upper computer.
Fig. 3 is the hardware implementing block diagram of low-frequency trigger, and this binary pair primary responsibility receives the triggering command that location processor is sent, and then responds the low frequency wake-up data that this instruction sends 125Khz.The power supply voltage of this binary pair is 12V, carries the voltage stabilizing carrying out 5V, then supply MCU and other circuit in binary pair inside.CAN module is responsible for communicating with location processor, receives the triggering command from the other side.The data of LF transmitter module response MCU send order, with high-power outside radiate low signal, wake the tire pressure module of inside tires up.
