Abstract
The utility model discloses a diagnosis refresh tool used for automobile maintenance, which is characterized in that after a central processor receives the instruction of a button control module, the content of an SD card is read, the read data is exchanged with the data of the controller of an object automobile body, and processed information is displayed on a display module. According to the structure, the diagnosis refresh tool used for automobile maintenance possesses the advantages as following: I, a computer is saved, fault diagnosis and software updating are more convenient; II, data storage and extraction are carried out in the SD card, which is convenient and fast; and III, production cost is low, and large-scope popularization is practical.
Description
Technical field
The utility model relates to the maintenance of automobile, particularly a kind of diagnosis refresh tool during for vehicle maintenance.
Background technology
When Automobile Design development phase and after-sales service, fault detect and Refresh Data all are very important.Take the automatic gear-box controller as example, the renewal of the modification of software, data is inevitable on stream.Even after the vehicle listing, possible software still can exist BUG or the improved place of some needs, thus can conveniently carry out software upgrading to vehicle, and the positioned vehicle fault is very important in vehicle maintenance fast.
For a whole-car firm, in the coupling of every money vehicle, because software constantly is optimized, nominal data also constantly updating, certainly will be wanted the frequent software upgrading of carrying out so simultaneously.To take programming apart extremely inconvenient and controller is disassembled from car at every turn, and some controller is that waterproof etc. considers that tightness is very high simultaneously, more is not easy to take apart.And along with the CAN bus popularizing that car load is used, refresh so that problem obtains convenient the solution by car load CAN.But all be unable to do without computer when automobile being carried out fault diagnosis and software refreshing, while need operating personnel holding notebook that automobile is safeguarded, efficient is low at every turn.
When automobile is safeguarded, can avoid using computer, so that fault diagnosis, software refreshing is more convenient is the problem that prior art need to solve.
The utility model content
Technical problem to be solved in the utility model is, a kind of diagnosis refresh tool during for vehicle maintenance is provided, and when automobile is safeguarded, can avoid using computer, so that fault diagnosis, software refreshing are more convenient.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of diagnosis refresh tool during for vehicle maintenance, it is characterized in that: described instrument is that content and the target carriage body controller that central processing unit accepts to read after the instruction of key control module the SD card carries out exchanges data, and the information after will processing shows at display module, and the data of utilizing storage in the SD card are with the diagnosis that realizes this instrument and the function of software refreshing.
The model of described central processing unit is MCF52259.
Be integrated with in the described central processing unit and be the SPI mode communication between SPI module and the SD card.
Be integrated with the CAN communication module in the described central processing unit, be connected to outside CAN transceiver, and the model of CAN external transceiver is TJA1050.
Integration USB module in the described central processing unit.
A kind of diagnosis refresh tool during for vehicle maintenance, owing to adopt said structure, this instrument has the following advantages: 1, enough avoid using computer, so that fault diagnosis, software refreshing are more convenient; 2, in the SD card, carry out data storage and extraction, convenient and swift; 3, production cost is lower, and is suitable for large-scale promotion.

Embodiment
The utility model is based on the diagnosis refresh tool design of SD card 2, and this instrument is by being connected with car load CAN bus, the refreshing and the operation such as fault diagnosis of realization data.By the introducing of SD card 2, only need to data copy in SD card 2, need not connect again the extras such as computer, can carry out Refresh Data.Designed simultaneously the renewal that has made things convenient for instrument self based on the bootloader of SD card, for the later on expansion of function provides the foundation.
As shown in Figure 1, for realizing that above-mentioned functions the utility model is that content and the target carriage body controller 3 that reads SD card 2 after the instruction accepted by 4 of key control moulds of central processing unit 1 carries out exchanges data, and the information after will processing shows at display module 5, and the data of utilizing the 2 interior storages of SD card are with the diagnosis that realizes this instrument and the function of software refreshing.
The model of central processing unit 1 is MCF52259.Be integrated with in the central processing unit 1 and be the SPI mode communication between SPI module and the SD card.Be integrated with the CAN communication module in the central processing unit 1, be connected to outside CAN transceiver, the model of CAN transceiver is TJA1050.Central processing unit 1 interior integration USB module.
The basic procedure of whole design as shown in Figure 6.Central processing unit 1 powers on and checks first whether equipment itself will carry out Refresh Data afterwards.Be checked through access arrangement refresh mode when refreshing button and pressing when when start, carry out 2 initialization of SD card, read that corresponding document refreshes equipment self in the SD card 2.Do not refresh button and enter the normal procedure entrance by next redirect when being checked through, each hardware of initialization, the Presentation Function interface, the operator function such as selects corresponding function to enter to carry out to diagnose, refresh by button.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
