Fault diagnosis system for practical training equipment

Abstract

The invention discloses a fault diagnosis system for practical training equipment. Compared with the prior art, the system comprises a diagnosis signal sending module, a detection signal reading module, a fault judgment module, a fault reconfirmation module and a central processing module. The fault judgment module is used for judging that an experiment check table is in a normal state or an abnormal state according to a detection signal; the fault reconfirmation module is used for judging whether or not the experiment check table has a fault again according to the detection signal when the fault judgment module judges that the experiment check table is in the abnormal state and also used for sending a fault code to the central processing module when it is judged that the experiment checktable has a fault; the central processing module is used for analyzing the fault of a device or a circuit according to the fault code and sending the fault code to an examination terminal. Compared with the prior art, the fault diagnosis system for the practical training equipment has the advantages that the labor can be replaced, fault diagnosis on refrigeration check equipment is completed, thesubjectivity of manual diagnosis is overcome, and the fault diagnosis efficiency is improved.

Description

technical field [0001] This application relates to the technical field of teaching assessment instruments, and more specifically, to a fault diagnosis system for training equipment. Background technique [0002] The refrigeration assessment equipment can be used as a skills certification examination platform, a skills competition platform, and a skills training and learning platform for the refrigeration system. The refrigeration examination equipment includes training and examination modes, and supports Internet remote practice functions. Examination answer evaluation is performed by the server according to the situation, using automatic scoring by comparison method, automatic scoring by matching method, and manual-assisted scoring. [0003] With the continuous increase of the functions of the refrigeration assessment equipment system, the system structure is becoming more and more complex. Any small fault may cause the equipment system to work abnormally and affect the nor...

Problems solved by technology

[0003] With the continuous increase of the functions of the refrigeration assessment equipment system, the system structure is becoming more and more complex. Any small fault may cause the equipment system to work abnormally and affect the normal execution of assessment tasks.

At present, through manual diagnosis of refrigeration equipment failures, not only will the diagnosis be subjective, but also the operation efficiency will be low.
