Problems solved by technology

In the existing relay teaching process, the teaching of the relay can only be done by setting the fault of the relay on the physical vehicle, and the process of fault setting will cause certain damage to the vehicle, resulting in the failure of the teaching vehicle to operate normally , thus affecting the development of teaching; on the other hand, the fault setting method of simulating relay faults through physical vehicles is relatively simple, so that students do not have a thorough grasp of the working principle of relays, which will affect the quality of teaching

Abstract

The invention discloses a relay fault simulation circuit and a relay teaching board. The relay fault simulation circuit comprises a fault setting unit and a fault state display unit, wherein the faultsetting unit is connected with the fault state display unit; the fault setting unit is used for setting fault types of a relay; the fault state display unit is used for displaying corresponding faultstates according to fault types set by the fault setting unit. The relay fault simulation circuit provided by the invention can be used for simulating the fault types of the relay and replacing the prior art which needs to carry out simulation teaching on the faults of the relay through a real car, so that the wear and tear of the real car is reduced; the circuit is used for carrying out the fault simulation and the fault simulation is more accurate, so that a better teaching effect can be obtained.

Description

technical field [0001] The application belongs to the technical field of relay teaching, in particular to a relay fault simulation circuit and a relay teaching board. Background technique [0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. The relay has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. In the existing relay teaching process, the teaching of the relay can only be done by...
