Semi-physical simulation vehicle-mounted bus system teaching and fault diagnosis practical training platform

Abstract

The invention discloses a semi-physical simulation vehicle-mounted bus system teaching and fault diagnosis practical training platform comprising a computer simulation assembly, a display and voice assembly, an information exchange assembly, a virtual sensing signal feedback assembly, a vehicle-mounted bus module, a function node, a vehicle manipulation control device, a display instrument, a vehicle-mounted power supply module and a practical training platform. According to the invention, a semi-physical form is adopted; the vehicle-mounted bus module, the vehicle manipulation control deviceand the display instrument all adopt real loading equipment; sensors and executing mechanisms of all function nodes of the vehicle-mounted bus network are achieved through the computer virtual graph technology. During the teaching process, energy consumption is low, part abrasion is extremely small, and faults are set in software in the computer simulation assembly; the sensor and the executing mechanism are virtual parts; fault simulation can be conveniently achieved; the platform is particularly suitable for being repeatedly used in teaching scenes, teaching activities are completed with lowcost and low risk, and the intelligent level of teaching is improved.

Description

technical field [0001] The invention mainly relates to the technical field of teaching equipment, in particular to a semi-physical simulation vehicle bus system teaching and fault diagnosis training platform.

[0002] With the continuous development of automobile electronic control technology, the traditional point-to-point wiring design can no longer meet the requirements of modern automobile control. The electronic control of vehicles is generally based on the vehicle bus network. This technological innovation not only improves the performance of vehicle control, but also greatly increases the demand for talents in the design, production and maintenance of vehicle electronic control systems in the industry.

[0003] Based on the huge demand for talents, many colleges and universities and vocational colleges in China have set up courses related to automotive electronic control technology. System simulation, or use real vehicles for teaching, domestic patent: a physical teaching model of bus CAN bus, patent number 201620336902.7, provides a physical teaching model of automobile bus for teaching, used for vehicle network troubleshooting training, domestic patent : Teaching experiment platform of automobile body network control system, patent No. 201210389158.3, provides a kind of teaching experiment platform of automobile body network control system, adopts simulation body and real vehicle bus network, realizes the experiment teaching of automobile body network control system, however, currently There are certain deficiencies in the teaching methods or teaching equipment. The way of using the teaching experiment bench panel is often based on factors such as cost and space, and only installs the bus system and electronic and electrical components while ignoring the mechanical actuators, electric control and mechanical mechanisms of the vehicle. It is a whole, and the teaching completely separated from the mechanical mechanism will make students lack an overall understanding of vehicle control. There are also shortcomings in the way of using real vehicles as teaching equipment. For example, the space of real vehicles is relatively small, which is not conducive to the development of multi-person teaching, especially For the school's primary introductory teaching, the efficiency of real vehicle equipment teaching is low, and the currently disclosed technical means are mostly used in the principle teaching process, and there are few technical means for the troubleshooting teaching of the vehicle bus system
