Description
Frequency conversion air conditioning energy saving, fast refrigeration (hot) and comfort good welcome by consumers, but the frequency conversion air conditioning structure is complex, especially the circuit control part is relatively complex, the dragon company based on the characteristics of frequency conversion air conditioning circuit control, development of the yalong YL – 1550 – b type frequency conversion air conditioning electric examination unit training, the device shows the real frequency conversion air conditioning electrical control principle, and has many practical functions.The device is also suitable for the practical training of mechanical and electrical majors, and for the identification and assessment of intermediate and senior workers and technicians in refrigeration and related majors.
Сharacteristics
The device is based on the control circuit of variable frequency air conditioner as the object of practical training and can make the trainees master the basic principle and maintenance technology of variable frequency air conditioner variable frequency circuit.The examination board is printed with the inverter air conditioner electrical control circuit diagram and test points. Students can understand the principle of the circuit diagram on the examination board, and use the instrument to detect, analyze, judge and find faults at the test points to improve their ability to judge faults.
1. The device adopts yalong intelligent practical training and assessment system software as the platform, and its hardware part is composed of teacher’s computer, student’s computer, fault setting circuit board, assessment circuit and network.The software consists of teacher assessment system and student assessment system.
2. Function description: the teacher’s machine has the functions of question editing, question issuing, rewinding, result analysis, result saving, printing and so on.The student machine has the main functions such as registration, question receiving, fault point setting, answer receiving, grading, paper handing in and result inquiring.
Principle 3. Note: the teacher in the teacher the treadmill test editor, and will be sent over the network editor good paper on students, students according to the fault phenomena in the assessment of circuit boards for testing and fault point search, and typing the answers to the student machine, the machine gives the corresponding students only on test scores, and to save the answer back to the teacher machine, for later queries to print;
4. Students use the complex knowledge type of answer process: each failure point must answer four questions, namely the failure phenomenon, the possible cause of the failure, the detection method, the location of the failure point.
5. The examination system can send different test questions to different students at the same time;
