Circuit fault setting encryption method for training and examination

Abstract

The invention relates to a circuit fault setting encryption method for training and examination. According to the invention, the circuit fault can be set conveniently in a hidden manner when the encryption circuit replaces a normal circuit element; in the device, normal elements and a plurality of fault-liable elements are preset, and a certain fault is set through the encryption circuit and a gating device; and due to the adoption of the encryption circuit, the fault is random and disguised, and a student can detect the fault only through an electric measuring device. Therefore, the abilities of the student utilizing the electric measuring device for measuring and analyzing circuit are trained and tested favorably, thereby achieving the preset purposes of the training and examination; as the normal and faulty elements are pre-set, the fault setting process is only the process of operating the gating device, so as to allow the fault setting to be simple and feasible, and realize the high efficiency of the work; and besides, the disassembly during the training and examination is avoided, so the main normal and abnormal elements have low probability of wastage, accordingly, the experiment circuit device has serviceability.

Description

technical field [0001] The invention relates to a circuit encryption technology, in particular to a circuit fault setting encryption method used for training and examination. Background technique [0002] In the training and examination of electronic maintenance technology, in order to cultivate and test students' ability to measure and analyze circuits, it is required to set different faults in the experimental circuit. These failures should be unpredictable to the students who are trained and tested, and have the randomness of the failure; and generally require that the failure is not easy to be directly found by the naked eye, and often need to be measured by electronic measuring instruments, which has the concealment of the failure. Under this requirement, it is not easy to set up faults with general experimental circuits. Because, the general experimental circuit setting failure is to replace the faulty component with a normal component. If the appearance of the faulty...
