Background technology
Domestic automobile industry develop rapidly: the blowout development that the domestic automobile sales volume has experienced several years still keeps rapid growth under the situation of soaring oil prices.According to statistics, the newly-increased vehicle in Tianjin was 140,000 in 2007, average every day is sold 995 of new cars by Beijing, and this means per three days will satisfy the hi-tech maintenance and service of year 3000 automobiles in the tame medium scale automobile services of same seat urban construction one enterprise.The rapid growth of sale of automobile amount, application has launched wide development space with service industry to automobile.According to statistics, at following 3 years, automobile is used with service industry 800,000,000,000 yuan of markets every year approximately.
Current domestic automobile vocational education teaching situation: because the growth at full speed of sale of automobile amount causes the relevant industries requisition to increase sharply.Six ministries and commissions of country have started " talent in demand cultivates the training engineering " in 2004, classifying four kinds of talents such as automotive operation and maintenance as " technical ability type talent in demand " accelerates to cultivate, country and each place government all in the input that strengthens the automobile vocational education, make China's automobile vocational education cause present thriving, flourish good situation.But, on Automobile Complex system material object, carry out skill training, drop into excessively, become wood too high, can't satisfy the requirement of skill training, also there is a big difference for student's the practical operative ability and the requisition of industry and enterprise.
Electron controls technology is introduced automotive fittings in a large number: along with the develop rapidly of electronics industry and auto technology, Hyundai Motor extensively adopts control fuel injection technology (EFI), Electronic Control ABS (Anti-lock Braking System) technology (ABS), Electronic Control safety airbag technique (SRS), electronic automatic transmission technology (ECT) and CAN-BUS Field Bus Control Technology, vehicle maintenance and fault diagnosis maintenance activity, be different from and satisfied simple in the past mechanical fault diagnosis and maintenance, and be conceived to more electronic failure and electromechanical integration Fault Diagnosis, the maintenance technology service, also depend on more and use advanced computer to detect, diagnostic device, pass through data-flow analysis, the analysis of complex art such as wave form analysis and tails assay is judged, therefore, current automobile failure diagnosis and upkeep operation, difficult point is at electronic failure and electromechanical integration Fault Diagnosis and eliminating, it be one technical very strong, be again the very strong work of operability simultaneously, cultural knowledge to the practitioner, Specialized Theory, technical merit, overall qualities such as testing equipment use are had higher requirement, and this is automotive operation and maintenance professional domain skilled talents place in short supply.The theory of automotive operation and maintenance service is along with right-about is also taking place in the renewal of automotive engineering, and economy, rationality, validity principle more and more come into one's own, the principle that outstanding the embodiment " puted prevention first, regularly detected compulsory maintenance, repair on technical conditions ".Also, several even tens computers are housed all on each automobile, just are the interconnected condition precedent of having created of automotive engineering real training simulator just because of electronic installation widespread use on automobile.
Virtual reality technology (Virtual Reality) claims clever border technology again, and it is to be the nineties in last century the technology that scientific circles and engineering circle are paid close attention to.Its rise is for new research field has been started in the development of human-computer interaction interface; For the application of intelligence engineering provides new interface tool; For the large-scale data visualization of all kinds of engineerings provides new describing method.The characteristics of this technology are: computing machine produces a kind of artificial virtual environment, this virtual environment is the three-dimensional space that constitutes by computer graphical, or other actual environment is organized into goes to produce realistic " virtual environment " in the computing machine, thereby make the user visually produce a kind of sensation of being immersed in virtual environment.
But pure virtual reality technology can't satisfy the simulated training of the complication system resemble the automobile again.In automotive operation and service engineering education and instruction, the learner not only needs good " feeling of immersion ", good " feel " also will be arranged, by touch feel, vision and the sense of hearing, the unification of realization theory and practice, cultivate large quantities of existing solid foundation knowwhies, the high-quality talents of consummate practical operative ability is arranged again.And the actual situation fusion is the important development direction of virtual reality technology from now on, all has important use at aspects such as complex product design, engineering design demonstration, complex system simulation training, recreation, studies and is worth.
The utility model content
At the problems referred to above, the collaborative work device that the utility model provides a kind of Automobile Complex system simulation training actual situation to merge, it is to use RS232/RS485/UNB network interface and netting twine, with the interconnected composition LAN (Local Area Network) of various automotive engineering real training simulator hardware, student test terminal and real training simulator hardware are connected to form the simulation station by RS232/RS485/UNB/CAN communication interface and data line, multimedia animation software and other teaching resources are embedded hardware system, form a kind of collaborative work of actual situation fusion and the device of study.The technical scheme of its technical solution problem is: with the motor car engine practical traning platform, the automatic transmission practical traning platform, ABS ABS (Anti-lock Braking System) practical traning platform, the air bag practical traning platform, the automatic air condition practical traning platform, automotive electronics igniting and fuel injection practical traning platform, car bulb electrical equipment practical traning platform, vehicle-mounted CAN-Bus bus and multistation information transmission system practical traning platform, the automotive engineering real training simulator (1) that automobile assembly object teaching devices such as teaching car load and automobile electrically-controlled steering practical traning platform constitute, use remote console (2) by RS232/RS485/UNB network interface (3) and the interconnected composition LAN (Local Area Network) of netting twine (9), realize sharing of teaching resource with campus network (4) networking; Use RS232/RS485/UNB/CAN communication interface (5) student test terminal (6) to be connected with automotive engineering real training simulator (1), realize actual signal and DATA REASONING operation that many people freely participate in data line (10); Multimedia animation software and other teaching resources (7) are embedded hardware system, it is automotive engineering real training simulator (1), can show the three-dimensional animation, plane animation, principle of work animation, running parameter, maintenance flow process of this part assembly and parts etc. simultaneously, form the complete actual situation of a cover and merge the device of collaborative work and study.Owing to adopted standard interfaces such as RS232/RS485/UNB, can be according to teaching needs and course offered situation, the automotive engineering real training simulator (1) that various automobile assembly object teaching devices are constituted increases and decreases arbitrarily, freely inserts, a kind of automotive engineering real training of every replacing simulator (1), the test panel (8) that only needs to change above the student test terminal (6) just can carry out new modular instruction.The number of connection of student test terminal (6) also can increase and decrease arbitrarily, freely insert according to user number.
