Embodiment Construction

[0035] specific implementation plan

[0036] Manual fault setting: the structural composition includes a fault setting box (Figure 1-6), a fault setting panel, and a fault setting button. According to needs, toggle the fault setting button corresponding to the fault to be set to realize open circuit, short circuit, lap connection, grounding and other types of faults.

[0037] Set the fault of the signal modification type: the structural composition includes the fault setting panel (Fig. 4-1) in the fault setting box (Fig. 1-6), the resistance meter (Fig. 4-2), the battery box (Fig. 4-4), the resistor Table power switch (Figure 4-5) and circuit control switch (Figure 4-6), etc. On the fault setting panel (Figure 4-1), turn on the power switch of the resistance meter (Figure 4-5), turn on the circuit control switch (Figure 4-6), and tune the resistance value (Figure 4-3) to the expected value, because in the car Resistors are added to the electronic system circuit, so the volt...

Abstract

The present invention relates to a method and a device for artificially setting various automobile failures according to demands and also for clearing the set failures. In particular, artificially controlled recurrent appearance or disappearance of various failures on an experiment table for an actual automobile or for each electronic assembly system of the automobile can be realized to attain the purpose of the repeated use for teaching experiments. Failures include open circuits, short circuits, lap joints, earthed contacts, over-high or over-low signals, etc. Related types include feedback signal failures, supply voltage failures, reference voltage failures, correction signal failures, control circuit failures, data transmission quality failures, etc. Related failure data and information can be acquired with automobile service devices such as avometers, automobile oscillometers, general motor analyzers, exhaust analyzers, etc.

Description

Technical field [0001] The invention relates to a method and a device capable of artificially setting various faults of automobiles and clearing the set faults according to needs. In particular, it can be realized on the experimental platform of real automobiles or various electronic assembly systems of automobiles, artificially controlling various faults to repeatedly appear or disappear, and achieve the purpose of teaching experiments that can be used repeatedly. Background technique [0002] Automobile failure refers to the phenomenon that the automobile assembly or component assembly partially or completely loses the original design function. Automobile failure is an extremely complicated process from formation to development, especially the majority of automobiles currently in use adopt electronic control technology. Mechanical failures and electronic failures are often intertwined, which increases the need for quantitative and qualitative analysis of automobile failure...
