Practical training device capable of detecting wiring correctness of circuit automatically

Abstract

The invention discloses a practical training device capable of detecting the wiring correctness of a circuit automatically. The practical training device is provided with electrical parts for practical training and wiring sockets, the wiring sockets correspond to pins of each electrical part respectively, and an operator of practical training can connect corresponding wiring sockets via leads so that the electrical parts corresponding to the wiring sockets are connected to form a target practical training circuit. The practical training device is characterized in that the electrical parts for practical training comprise a controlled power supply which is used to supply power to the target practical training circuit, the practical training is also provided with a relay device and a controller, the relay device is provided with groups of changeover contacts, each group of changeover contacts corresponds to one pin of one electrical part, and each pin of each electrical part can work in the wiring, detecting and experimental modes by being connected to the controller via the corresponding changeover contacts and wiring socket. The practical training device is used for practical training of circuit wiring, and the electrical parts for electrical training can be avoided from damage caused by wiring mistakes of the operator.

Description

technical field [0001] The invention relates to a training device capable of automatically detecting the correctness of circuit wiring. Background technique [0002] Courses such as basic electrical engineering, electrical engineering certification, PLC, etc., even as early as middle school physics classes, you must learn to correctly wire the electrical components used for training according to the circuit schematic diagram, and then achieve a proficiency level. In teaching, students often make various wiring errors, such as short circuit, open circuit and so on. If there is a wiring error and the power is still on, it is easy to damage the electrical components used in training, affect normal teaching, cause economic losses, and even unnecessary personal injury. Therefore, it is usually required to be checked by the teacher before students are allowed to power on and run the circuit. But in this way, students have to wait for the teacher to check their circuits when they...
