CAN-BUS car vehicle network teaching training system

I. Introduction The teaching and training platform (hereinafter referred to as teaching units) using public cars (Bora BORA, Passat PASSAT, Audi and other optional models) Body Convenience CAN bus network, which demonstrates the linkages between the various systems and system Each module this process through the work of CAN data communication line; can set CAN line fault between modules and each module K line failure; through the physical demonstration and detection terminals on the front panel can be functional testing and fault analysis provides reference data. Second, the functional characteristics 1, draw a complete mass-vehicle network (CAN-BUS) (containing Comfort) system diagram on the panel. With a detection terminal, through a variety of instruments to detect signal parameters sensors, actuators, and other such as voltage, resistance, frequency; 2, by manipulating the control switch, can realize the control of different window motor and the rear-view mirror, the real demonstration Volkswagen vehicle during operation network (CAN-BUS) systems; 3, light-emitting diode display components work status; 4, fault simulation system can simulate the actual operating conditions, set a variety of common faults of the actual vehicle. Operating principle 5, security and central control system;; Details are described fault simulation setting means 6, equipped with diagnostic seat, can read the fault code and data stream and the like; 7, with a PC-CAN data exchange software and interface cable , CAN data can be read on the computer, observe the CAN data exchange. Each node on the CAN bus line inspection ID, detection status frame, control and other important data frame; control data, artificially controlled. Through man-machine communication, CAN node according to instructions specified work online instant control "test bed"; 8, CAN-BUS physical signal waveform analysis and fault diagnosis; 9, chassis part of the bench, table reservations 30cm wide space, easy placement testing equipment and instrumentation / test reports in the like, the surface paint technology, with self-locking casters; 10, automobile paint high temperature paint handling; installation of AC earth leakage protection device; rotating components outside the installation of protective devices. Third, the technical parameters Dimensions: 1440mm × 550mm × 1850mm (length × width × height); Power: 220V AC voltage; operating voltage: 12V DC voltage; Operating temperature: -50 ℃ ~ 50 ℃ Fourth, the training system configuration (a ) Teach units. The teach-in desk using Volkswagen Passat B5 sedans CANS system. CANS with large color inkjet system schematic, and CANS electronic control unit as the center, each component system layout, to make clear the connection harness represent the same manner as the original vehicle wiring harness, so CANS system at a glance. Full show car data the structure and the circuit elements through the data transmission network transmission system implementation. By combining meter gateway control connections, the power system data network and data network connections comfort systems to form a complete whole vehicle CAN network system. Steering gear switch, embodied in the instrument cluster display network transport processes; operated power windows, mirrors, central locking reflects network during transmission. You can set the CAN wire fault between modules and each module K line failure; through the physical demonstration and detection terminals on the front panel can be functional testing and fault analysis provides reference data, a complete grasp of structure and theoretical knowledge CANS system, understanding CANS the role of the various electronic control system components, principles malfunction. (B) CAN-BUS development of teaching practice and experiment boxes. Supporting hardware: 1, Sweden imported high USBcan bus analyzer based on PC's. 2, Shenzhou IV No. STM32F107VCT6 breadboard (supporting 1CD Disc). 3,3.2 inch TFT touch screen. 4, DC5V power cable. 5, USB5V power cable. 6, JLINK V8 debugger. 7, remote wireless remote control. (C) USBcan bus analyzer -Kvaser USBcan II Guangzhou Chi-dimensional imported from Sweden Kvaser USBcan II is a USB-based two-channel CAN bus analyzer, one channel for high-speed CAN, an alternative channel for high-speed CAN, low-speed CAN or single-wire CAN. (Iv) CAN-BUS teaching training system supporting software 1, Kvaser CanKing Kvaser CanKing bus analysis software is a free CAN bus monitor and the common diagnostic tool. It is particularly suitable for interactive development. You can easily send CAN message and study their effects on the target module. You only need a Kvaser CAN interface. Kvaser CanKing totally free. 2, CANlib software development portfolio supports the following programming software: Microsoft Visual C ++ (also supports C language) Borland C ++ Builder (as well as the old Borland C ++ compiler) - also supports C language Borland Delphi (all versions) Microsoft Visual Basic and VB.NET Microsoft C # 3, based on LabVIEW CANlib user secondary development of software developer guide highlights some examples of labview developed to help users familiar with labview secondary development process as soon as possible. Before you write programs, first make sure the user's computer is installed correctly labview8.6 or later, and successfully register it. CD inside the "kvCanVi" folder "kvCanStatExample" program can be used to send and receive data on the bus. kvCanVI program which contains many routines with advanced features. Users can use these sub-vi conduct programming.
