Description
Technical field
The present invention relates to monitoring automobile tyre pressure technology, what be specifically related to is a kind of launch terminal and method of mating different TPMS main frame.
Background technology
TPMS (TirePressureMonitoringSystem) i.e. Tire Pressure Monitoring System, be mainly used in carrying out Real-Time Monitoring to the pressure and temperature of motor tire inside, and report to the police when inside tires situation is abnormal, remind chaufeur, avoid accident to occur.TPMS system is divided into indirect type and direct-type two kinds.Direct-type TPMS system by installing a built-in sensors on the tire dice of tire, sensor comprises the bridge type electron gas pressure induction installation of induction air pressure, air pressure signal is converted to electric signal by it, by feedway, signal is emitted, to realize under driving or static state, the pressure of real time monitoring tire, the data such as temperature, and pass-through mode is transmitted into receptor, show various data variation over the display or with forms such as buzzings, remind motorist, and exceed Secure Threshold (this threshold value sets by telltale) time at tire flat and pressure change and report to the police, with guarantee driving safety.The actual wink that can measure each inside tires due to immediate system at any time presses, and is easy to determine fault tire, has the advantages that accuracy rate is high, therefore apply comparatively extensive.
In the automobile that each car production manufacturer of Present Global produces, TPMS system mainly adopts 315MHz/433MHz, the modulation system of ASK and FSK.Due to the communication frame format difference to some extent of each auto vendor TPMS system, TPMS launch terminal is so just caused to there is coupling poor compatibility, problem that cannot be general, therefore the launch terminal of TPMS has more than tens kinds on the market, and each other can not be general mutually, if the TPMS launch terminal be arranged in motor tire damages, same brand or of a sort launch terminal just must be changed, otherwise cannot use, the replacement cost of user will be caused like this to increase.
Summary of the invention
The object of the present invention is to provide a kind of launch terminal and method of mating different TPMS main frame, to solve current TPMS launch terminal coupling poor compatibility, cannot be general, the problem that replacement cost is high.
The object of the invention is to be achieved through the following technical solutions.
A kind of launch terminal mating different TPMS main frame, comprise micro-control unit, the data sampling unit be connected with micro-control unit, power supply unit and terminal radio frequency unit, wherein also include ROMPaq processing unit and terminal staging interface unit, described ROMPaq processing unit is connected with terminal staging interface unit by micro-control unit, obtain upgrade data by terminal staging interface unit, and upgraded according to obtained upgrade data by ROMPaq processing unit;
This system also includes a reset unit be connected with micro-control unit, and this reset unit carries out system reset by micro-control unit to the TPMS launch terminal after upgrading.
This system also includes main memory unit and standby memory cell, described main memory unit is connected with micro-control unit respectively with standby memory cell, by micro-control unit controls, upgrade data is temporary in standby memory cell, and correspondence copies in main memory unit, by ROMPaq processing unit, upgrading is carried out to the upgrade data in main memory and control.
Preferably, described upgrade data comprises No. ID or sequence number of the binary file of decoding TPMS system communication protocol generation and the TPMS transmitter of needs replacement.
The present invention compared with prior art, beneficial effect is: the launch terminal of the different TPMS main frame of coupling provided by the invention and method, by decoding to different automobile TPMS system communication protocol, generate the projector binary file corresponding with this TPMS system, obtain No. ID or sequence number needing the TPMS transmitter of replacing, then above-mentioned information correspondence is written in TPMS launch terminal, to realize this TPMS main frame launch terminal and original TPMS main frame carries out proper communication.The present invention is by the general TPMS launch terminal of upgrading, the data of the TPMS launch terminal of any vehicle can be mated, can the TPMS system of compatible market overwhelming majority vehicle, can be used in after-sales service in a large number, use No. ID or sequence code of first wife's terminal, directly replace original launch terminal, do not need the data revising any former car ECU, and the present invention to change tire pressure terminal simple and convenient, there is huge commercial value.
Accompanying drawing explanation
Fig. 1 is the system principle diagram of TPMS launch terminal of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to shown in Fig. 1, Fig. 1 is the system principle diagram of TPMS launch terminal of the present invention.The invention provides a kind of launch terminal mating different TPMS main frame, it is general that this terminal can realize between different automobile types, and being mainly used in solving current different automotive type TPMS launch terminal cannot general, coupling poor compatibility and the high problem of replacement cost.
Wherein launch terminal of the present invention includes micro-control unit, main memory unit, standby memory cell, ROMPaq processing unit, power supply unit, data sampling unit, reset unit, terminal radio frequency unit and terminal staging interface unit.
Main memory unit, standby memory cell, ROMPaq processing unit, power supply unit, data sampling unit, reset unit, terminal radio frequency unit are all connected with micro-control unit with terminal staging interface unit, power supply unit is used for powering to micro-control unit and other unit, and data sampling unit is used for sampling to the parameter such as tire pressure, temperature of motor tire; The parameter such as tire pressure, temperature that sampling obtains, then for setting up the communication connection with automobile middle control device, sends by terminal radio frequency unit; Micro-control unit is used for carrying out processing controls to above-mentioned parameter and signal, and sets up upgrading connection, obtains upgrade data; ROMPaq processing unit is used for carrying out upgrading according to the upgrade data obtained to launch terminal and controls, and verifies upgrade data simultaneously; Standby memory cell is used for temporarily storing upgrade data, and under ROMPaq processing unit controls, upgrade data is copied in main memory unit, carry out upgrading processing, after ROMPaq completes, exit ROMPaq, and start reset unit this TPMS launch terminal is resetted, make the TPMS communication protocol in TPMS launch terminal be upgraded to the communication protocol of requirement, No. ID simultaneously in this TPMS launch terminal or sequence number correspondence replace No. ID or sequence number of first wife's launch terminal.
And after launch terminal system of the present invention restarts from main memory unit, new TP MS terminal and the proper communication of original vehicle TPMS system can be made, do not need the ECU data revising original vehicle TPMS system simultaneously.
