6  Supporting virtual reality integrated teaching system

a. Teaching effect and concept: the automobile virtual reality integration integrated teaching system aims to make theoretical teaching and practical teaching interact and integrate. On the one hand, improve the practical ability of theoretical teachers, train their theoretical level, and cultivate a high-quality teaching team. On the other hand, teachers integrate theoretical knowledge into practical teaching, let students learn by doing, understand theoretical knowledge and master skills in learning and practice, and break the boundary between teachers and students. Teachers are among and around students. This way can greatly stimulate students' enthusiasm for learning, enhance students' interest in learning, and actively summarize students while learning and practicing, It can achieve twice the result with half the effort. The integration of theory and practice teaching software breaks through the disconnection between theory and practice, and the teaching links are relatively concentrated. It emphasizes giving full play to the leading role of teachers. By setting teaching tasks and teaching objectives, teachers and students can teach, learn and do at the same time, build a quality and skill training framework in the whole process, enrich classroom teaching and practical teaching links, and improve teaching quality. In the whole teaching process, theory and practice are carried out alternately, and intuition and abstraction appear alternately. There is no fixed principle of "reality before reason" or "reason before reality", but there is reality in reason and reason in reality. Highlight the cultivation of students' practical ability and professional skills, and fully mobilize and stimulate students' interest in learning.

b. Composition: the virtual reality integration teaching platform is composed of wireless remote communication module, training system and theory reality integration teaching software.

c. Wireless remote communication function: it has industrial design and is applicable to all kinds of teaching equipment. It has built-in software and hardware watchdog and does not crash or drop the line. Support transparent data transmission. Communication mode: WiFi hotspot based on IEEE802.11 standard is adopted, effective communication distance: open space: 80m, interface rate: 150m, frequency range: 2.412ghz-2.484ghz.

4. Fault system

4.1 the fault system adopts the way of graphical fault setting, and is configured with standard circuit diagram, which generally corresponds to the panel diagram of training equipment. Teachers can directly set or clear faults through the circuit diagram. It has the characteristics of intuitive operation and concealed fault setting.

4.2 teachers can set faults through single point fault setting, combined fault setting, assessment fault setting and other methods, and send fault setting instructions to the training equipment remotely through WiFi. Students can measure the voltage and resistance of relevant systems of the training equipment through mechanical instruments multimeter, and use oscilloscope to observe the waveform curves of different signal amplitudes varying with time, It can also be used to test various electric quantities, such as voltage, current, frequency, phase difference and adjustment amplitude. At the same time, it can read fault codes and analyze data flow through diagnostic equipment to judge fault points, analyze their causes and eliminate them, which greatly improves the students' initiative and judgment skills. In the fault setting stage, teachers can conduct routine assessment on the troubleshooting process of students by limiting the troubleshooting time, which is helpful to formulate effective training measures, so as to improve the results of Vocational and technical training.

4.3 the interface of the fault system is clear and easy to understand. The fault status identification has options such as "open circuit", "virtual connection", "release" and "close" respectively to truly simulate the typical fault phenomena of the training equipment.

4.4 the fault system does not have the memory function by default to avoid stopping in the middle of the training and forgetting to cancel the fault, which will cause hard fault to the training equipment and affect the normal operation and later training.
