The device comprises a machine tool electric apparatus circuit, a first input interface, a second input interface, a push button plate, a PLC, an output interface, a PLC control auxiliary relay, a fault setting auxiliary relay and a computer, wherein, the PLC is connected with the push button plate by the first input interface, the push button plate is connected with the machine tool electric apparatus circuit by the second input interface, the PLC control auxiliary relay and the fault setting auxiliary relay are connected with the machine tool electric apparatus circuit, the PLC is respectively connected with the PLC control auxiliary relay and the fault setting auxiliary relay by the output interface, and the computer is connected with the PLC. The method closely combines two training assessment methods or technologies, has strong practicality, facilitates the training and performance assessment of trainees, and improves the understanding of beginners on the PLC and the relay contact electricity.

Description

technical field [0001] The invention relates to an electrical troubleshooting and PLC application skill training assessment device and a method thereof. Background technique [0002] Machine tool electrical troubleshooting and programmable logic controller (PLC) application skills are necessary skills for modern electromechanical technical personnel, and are also one of the key technologies of modern electrical control. [0003] Shanghai Second Polytechnic University's "Numerical Control Semi-Advanced" and "Maintenance Electrician" skills training and assessment have been held for many years. Many sessions of students have been trained and rich teaching experience has been accumulated. At the same time, some new disadvantages have been exposed: [0004] 1) For the training assessment of electrical troubleshooting, the fault setting is manually set by the examiner in advance, and the subjective judgment affects the students' learning and performance assessment, which will lea...

Problems solved by technology

[0004] 1) For the training assessment of electrical troubleshooting, the fault setting is manually set by the examiner in advance, and the subjective judgment affects the students' learning and performance assessment, which will lead to the instability of the students' ability and performance;

[0005] 2) The training and assessment of PLC application skills. The input and output of PLC are all simulated objects. The assessment of PLC application skills is based on the program status and indicator light logic, which lacks practicality and deviates from the actual control of the enterprise site;
