Automobile basic circuit fault diagnosis checking system and method

Abstract

The invention belongs to the technical field of automobile teaching, and discloses an automobile basic circuit fault diagnosis checking system and an implementation method. A circuit that a switch isadopted to control relays, and the relays control bulbs is adopted; a single chip computer is used as the control center to connect with a serial port screen to obtain real-time relevant information;the single chip computer controls 19 relays and projects 'faults' into a basic circuit in real time. When a system enters a checking state, the countdown begins, and the 'faults' are projected into the circuit; trainees use a test lamp, a multimeter or a jumper wire to diagnose the faults of the circuit, and after the faults of a certain part are confirmed, an open circuit or a virtual connectionbutton of the corresponding part is clicked on the display screen. When an exam is over, the system lists trouble removal lists and student examination results. The system is very stable in practicalapplication, and enables the trainees to master firmly the use of the test lamp, the multimeter and the jumper wire, and multiple devices can work simultaneously to improve the checking efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobile teaching, and in particular relates to an automobile basic circuit fault diagnosis assessment system and method. Background technique [0002] In the teaching process of the course "Implementing Primary Maintenance of Automotive Circuits", in addition to mastering basic knowledge, knowing diagrams, and analyzing circuit diagrams, learners also have an important basic skill - to use test lamps, multimeters and jumper wires to troubleshoot circuits Troubleshoot. At present, the skill assessment method for students to use "light test", "multimeter" and "jumper wire" to diagnose automobile circuit faults is still mainly manual assessment. The process of student assessment is a long waiting process. Generally, each teacher invigilates 2 students at the same time, or even invigilates 1 student. It takes a long time to complete the assessment of the whole class or year-round students, and it will tak...

Problems solved by technology

The process of student assessment is a long waiting process. Generally, each teacher invigilates 2 students at the same time, or even invigilates 1 student. It takes a long time to complete the assessment of the whole class or the whole grade, and it will take a long time after the assessment. A lot of time is spent sorting out the students' work orders and improving the performance evaluation; due to the long assessment time, the invigilator may be fatigued, or the skill level of each invigilator is different, and misjudgment of the student's assessment results may occur; during the manual assessment process, the invigilator may May have different "impressions" on the students, which will also have an impact on the assessment results

[0003] In summary, the existing technology has the following problems: low implementation efficiency

The assessment process, work order sorting, and performance evaluation will take a lot of time; the phenomenon of misjudgment in the implementation of the assessment process cannot be avoided; the fairness of the assessment process
