Teaching experiment platform of automobile body network control system

Abstract

A teaching experiment platform of an automobile body network control system comprises a simulation automobile body, a comprehensive experiment box, a computer, a universal serial bus-controller area network (USB-CAN) interface card, a 12V lead-acid storage battery for an automobile, a transformer converting 220V alternating current into 12V direct current, a network assembly, an automobile external lighting system, an automobile windscreen wiper system, an automobile window and rearview mirror system and an automobile door lock system, wherein the automobile external lighting system, the automobile windscreen wiper system, the automobile window and rearview mirror system and the automobile door lock system are arranged on the simulation automobile body. A body control module (BCM), a lamp connecting unit, a signal testing unit, a bus interface unit and an analog switch button unit for simulating actual automobile signals are arranged in a comprehensive experiment box. Three interfaces of the bus interface unit are bus interfaces of CAN-L, CAN-H and LIN networks of a CAN respectively and are used for measuring or connecting new network nodes directly. The teaching experiment platform has the advantages of being simple in structure, clear in principle, complete in functions, high in integration, good in openness, high in safety, good in simulation, convenient for large-scale manufacture and the like.

Description

technical field [0001] The invention mainly relates to the field of a teaching experiment platform related to automobiles, in particular to a teaching experiment platform applied to a vehicle body network control system. Background technique [0002] With the rapid development of the automobile industry and the advancement of automobile technology, the point-to-point control method of traditional body electronic devices has gradually exposed many problems: such as a large number of wiring harnesses in the car leading to wiring difficulties, troublesome car fault detection and maintenance, serious interference, and decreased stability. Wait. The use of bus-type body network control technology in the automotive field can effectively solve these problems, and automotive electronics has also been regarded as an important symbol to measure the development level of a country's automotive industry. At the same time, the society's demand for high-level automotive electronics resear...

Problems solved by technology

[0002] With the rapid development of the automobile industry and the advancement of automobile technology, the point-to-point control method of traditional body electronic devices has gradually exposed many problems: such as a large number of wiring harnesses in the car leading to wiring difficulties, troublesome car fault detection and maintenance, serious interference, and decreased stability. Wait

At present, the existing automotive electronic teaching experimental equipment has the following defects to varying degrees: some equipment is refitted from a real car, which is high in cost and heavy in weight, and is inconvenient to move and observe internal wiring; some equipment only integrates the components of the car body on the teaching panel In terms of performance, there is a big gap with the actual vehicle; some equipment selectively adopts electrical and electronic experimental devices, which are not very targeted, and use AC 220V working voltage, which is quite different from the DC 12V working voltage of automotive electronics, and there is a certain risk; some equipment Unable to simulate faults, lack of fault diagnosis functions, and unable to connect to a computer for online debugging, etc.

[0004] In addition, since automotive electronic teaching equipment is a non-standardized product, its technical performance, functions, safety and other indicators are mostly determined by the manufacturers themselves, resulting in a situation of uneven product levels, different professional levels, limited functions and chaotic prices.
