Development Of Simulation Training Software On The Morden Automotive Electrical System Troubleshooting With Virtual Reality

Virtual Reality (Vimlal Reality referred to as VR) technologies, VR technology combines computer graphics technology, sensor technology, multimedia technology, simulation technology, parallel real-time computing technology, artificial intelligence and other disciplines developed in recent years, rapid development and more active in the latest technology. VR technology through the simulation image for the user to create a three-dimensional world of physical objects can reflect changes in real time and interaction effect, see, hear, feel and other perceived acts of real experience, allowing users to directly participate in and explore the virtual objects in their own The role of the environment and changes, like being in a real world, have experienced a sense.Based on the study of virtual reality at home and abroad based on the current situation, analyzes the common faults of modern automotive electronic systems and the detection and diagnosis methods, focused on how to use 3Dmax modeling, VRML, Java and. Net technology interaction, the system test and Construction and testing of the "automotive electronic systems simulation training system", the system can take full advantage of existing relevant institutions and network equipment room, so that students at the same time training simulation for fault diagnosis. Specific content and conclusions can be summarized as follows:1. In the investigation at home and abroad on the basis of related references obtained is the rapid development of virtual reality technology and strong application stage, in the automotive electronic systems simulation training systems for the future of wide range of applications, has great application prospect.2. Modern automotive electronic systems and diagnostic methods common failure analysis(1) As more and more electronic technology into the car, auto configuration increasing, more and more advanced technology, but also to functional integration, control electronic, connection direction makes the standardization of automotive electronic system failure rate on the rise, and become more complex, automotive electronic system failure into a bus fault, electric control system failure, electrical system failures;(2) Diagnosis: bus fault diagnosis into the bus system failure and node failure, electronic control system diagnosis using communication style diagnostic instruments, waveform analysis, line detection, the main electrical system fault diagnosis using multimeter.3. Electronic systems design and implementation of digital model to analyze the system needs to model objects and precision grade, mainly 3Dmax modeling, modeling, real photos mainly after 3 view photoshop, import 3Dmax model, key positions focused on sculpture.4. Electronic simulation system design and implementation, analysis of the simulation system needs to be achieved, based on interaction requirements discussed at present the main ways and means to interact, scene construction requirements, the logic engine of the car's physical preparation, data Binding synthesis.5. Simulation system test and test, through the operation of the system several times using a test stand-alone operation of the system stability and maneuverability, the data comparison of the data engine and the real vehicle test, analyze the system errors and data with the real vehicle consistency. Version of the campus network testing room draw system stability and maneuverability.This system permits the whole class to join in an emulational trouble shooting to automobiles. And it is worth mentioning that this system make full use of the available resources in vocational college, such as computer room and network devices. Therefore, it is easy for students to manipulate and switch experimental items, and it is visual for them to manipulate an emulational testing equipment to assemble, disaeesmble and test. What's more, all the works are done by a small mouse. Meanwhile, according to the firm's workflow, emulational experiment system is programmed by computers, so that students could do experiments in a simulation scenario (workshop, station, field trials and testing equipment) In general, this system is typical of standard of accerssory testing, various methods and dynamical location based data, which gives students complete freedom of action or expression and brings their subjective initiative into play. Moreover, it is helpful for them to learn and go further researches on automotive electronic system, so that they can improve their compentency through emulational experiments, and get a good knowledge of a complete process of automotive trouble shooting by a mouse. In sum, this system achieves the result of automitive workshop analog simulation.
