Vehicle failure intelligent setting, practical training and check-out system and realization method thereof

Abstract

The invention discloses a vehicle failure intelligent setting, practical training and check-out system and a realization method thereof. The system comprises a test bench, a relay, a PLC (Programmable Logic Controller) and a touch screen, wherein the test bench is connected with the PLC through the relay; the system has a standalone edition mode and a network edition mode according to that whether the system is connected to the network or not; in the standalone edition, the PLC is directly connected with the touch screen; in the network edition, the system also comprises a computer which is connected with the touch screen and the PLC respectively, and the PLC is connected with the touch screen. The method is that a teacher can retrieve the test questions in an item pool through the touch screen or the computer and conduct failure setting on a vehicle on the test bench through the PLC and the relay; and a student can read the technical information in a data bank through the touch screen for conducting fault diagnosis and reporting the result to the PLC or the computer. The system and realization method can conduct intelligent failure setting, technical information storage and automatic scoring statistics, and improve practical training and check-out quality and efficiency.

Description

technical field [0001] The invention relates to the field of vehicle detection and maintenance professional training teaching and assessment equipment design, in particular to an intelligent vehicle fault setting and training, assessment system and its implementation method. Background technique [0002] Traditional car fault setting, practical training, and assessment rely on manual setting of faults, students to eliminate faults, teachers to check students' assessment results, and then evaluate the assessment results. This method of vehicle fault setting, practical training, and assessment has the following disadvantages: first, it takes a lot of time to write questions, hundreds of students, each with a set of fault test papers, and the workload is huge; It is very difficult to come up with good questions due to practical experience, especially for young teachers; third, the questioning is highly subjective and depends entirely on the teacher; fourth, auto fault setting i...

Problems solved by technology

This method of vehicle fault setting, practical training, and assessment has the following disadvantages: first, it consumes a lot of time to prepare questions, hundreds of students, each with a set of fault test papers, and the workload is huge; It is difficult to come up with good questions due to practical experience, especially for young teachers; third, the questioning is highly subjective and depends entirely on the teacher; fourth, auto fault setting is labor-intensive, time-consuming, and material-intensive, requiring experienced teachers or workers to do it manually. Facing a large number of cars, the workload of fault setting is huge; fifth, some car faults are difficult to set, such as poor contact of circuit components, sensor performance changes, engine load changes, etc.; sixth is assessment results Manual statistics are time-consuming and errors may occur

[0003] Chinese patent application 201010191389.4 discloses a network intelligent training assessment system, which reduces the workload of many fault setting, but the fault setting only stays in the circuit disconnection, short circuit and poor contact, and cannot set up auto parts (such as a large number of automobile sensors, Actuator, etc.) performance changes and failures of the car when it fails, and it is not possible to set the fault performance characteristics when the car's working conditions change (such as load and speed changes)
