Background technology
Along with the development of electronic technology, have that volume is little, cost is low, the ECU of high reliability is widely used in Vehicle Electronic Control, improve the performance of automobile, also make automotive system become and become increasingly complex simultaneously.Therefore, along with automotive electronics and integrated vehicle control tactics on automobile, apply increasingly extensive, vehicle safety and reliability requirement are promoting the development of Automobile Failure Diagnosis Technology and failure diagnosis apparatus.
Automobile fault diagnostic apparatus both domestic and external roughly has diagnostic trouble code decoding, removes diagnostic trouble code, shows the basic functions such as fault, storage failure information, but because the Auto analyzer in market is mostly for specific automobile development, even universal diagnostic equipment shields user detecting the operations such as instruction definition, New Deal interpolation, this type of standalone feature not yet has product development.Therefore, having the development platform that makes Auto analyzer become vehicle electric field from application apparatus from setting test instruction function becomes possibility, can expand the user field of product, makes equipment realize self-service upgrading.
Current external OTC, Shi Naibao, Siemens, BOSCH etc. have more typical automobile ECU failure diagnostic apparatus product to be widely used in auto repair.Because the application of domestic In-vehicle networking is later than abroad, development of automobile process also lags behind abroad a little, therefore such automobile ECU failure diagnostic apparatus product of domestic independent research, production is less, and the rapidity of its fault detect, accuracy, reliability and function etc. all have much room for improvement.
Auto analyzer handheld device function is simple, system upgrade is complicated, diagnosis object simplification, makes equipment not have versatility.Automobile for the different configurations of same model detects, and needs continuous whole updating software protocol, even upgrades hardware device, and this is also relevant with automobile production enterprise, automotive test equipment manufacturer's technical monopoly.The Auto analyzer operation response speed of most domestic-developeds is slower, and master controller cannot complete complicated operation.In-vehicle networking application is take K line and L line as main, the many employings of failure diagnostic apparatus On-Board Diagnostics (OBD) standard ISO 14230 and the ISO9141 relevant to K line, lack research and the application of the automobile ECU failure diagnostic apparatus to the On-Board Diagnostics (OBD) standard based on CAN bus, promote at home formation resistance for the equipment of application CAN bus like this.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of universal instruction of setting certainly Auto analyzer is provided, this diagnostic equipment adopts CAN bus communication pattern, can read failure code, show failure message, remove diagnostic trouble code, read dynamic dataflow display data stream, and can be from setting vehicle diagnosis instruction.
The technical scheme that the utility model is realized object is:
A kind of universal from setting instruction Auto analyzer, middle and upper part at panel is provided with touch screen displays, on the panel of touch screen displays dual-side, be respectively arranged with USB interface, RJ45 network interface, RS232 communication interface and CAN bus interface, K line and LIN line interface, SD draw-in groove, equipment indicating lamp, be respectively arranged with the external button of facility switching, memory module at the middle part of panel, be respectively arranged with equipment control button and printer, STM32 main control chip in the bottom of panel, control circuit is installed in panel.
And the control circuit of installing in described panel comprises MCU, host computer PC, USB interface, MAX232 module, RS232 serial communication interface, DM9000 network communication module, network transformer, Keysheet module, LED state lamp module, printer module, touch display screen module, CAN transceiver, esd protection module, OBD connector, LINK-line transceiver and DC-DC modular converter.
And described MCU selects STM32 control chip, network transformer adopts HR911105A, and CAN transceiver adopts the TJA1050 module of bus communication.
Advantage of the present utility model and good effect are:
1, this diagnostic equipment adopts CAN bus communication pattern, can read failure code, show failure message, remove diagnostic trouble code, read dynamic dataflow display data stream, can be from setting vehicle diagnosis instruction, can make equipment in the situation that of overall upgrading not, complete the detection to car body particular arrangement, make equipment can carry out secondary development, by configuration can one the multiple automobile component fault of the different car of machine testing system, depot, vehicle.
2, the command function of setting certainly that this diagnostic equipment adds, can independently write test instruction to different car body what's news and detect, and has not only saved the HardwareUpgring cost of automotive diagnostic installation, and has made diagnostic equipment itself possess the function of secondary development.
3, this diagnostic equipment can adopt CAN mode bus to communicate by letter with vehicle-mounted computer, simultaneously for the compatible K line of old money vehicle and LIN wire protocol.
4, this diagnostic equipment is universal checkout equipment, can read failure code, show failure message, remove diagnostic trouble code; Read dynamic dataflow, and display data stream.
