General teaching device for PLC logic controller of nuclear power station

Abstract

The invention belongs to the technical field of nuclear power station PLC teaching and particularly relates to a general teaching device for the PLC logic controller of a nuclear power station. The invention aims to design a set of portable and interesting PLC general teaching device. The device comprises two kinds of PLCs commonly used in a nuclear power station. The two kinds of PLCs share one set of peripheral circuits. By means of an Intouch upper computer equipped with an integrated computer, the interesting actual combat drilling is carried out according to the prompts of the upper computer. The switching value input, the switching value output and the analog quantity input of the PLC are explained step by step. A PLC online teaching plan with pictures and texts is matched, so that atrainee can eliminate worry about the PLC in a short period of time and quickly master the operation essentials of the PLC. The device is characterized by comprising a S7-300 type PLC, a GE 90-30 type PLC, a power switch, a PLC switching device, an integrated computer, a peripheral circuit unit, a button unit, an interface unit and a temperature sensor.

Description

technical field [0001] The invention belongs to the technical field of PLC teaching in nuclear power plants, and in particular relates to a universal teaching device for PLC logic controllers in nuclear power plants. Background technique [0002] PLC (Programmable Logic Controller), that is, programmable logic controller, is widely used in today's nuclear power plants because of its high integration, modular design, and programmable control methods. [0003] However, based on the nuclear safety culture of nuclear power plants, PLC equipment in on-site operation is not allowed to be operated at will. If employees want to improve their PLC skills, they must either read the boring manuals themselves, or apply for high training fees to go out to attend training courses, or they can only use the PLC equipment in operation on site for training. [0004] The training class has the advantages of concentrated training time, experienced teachers, detailed teaching plans, and complete...

AI Technical Summary

Problems solved by technology

[0004] The training class has the advantages of concentrated training time, experienced teachers, detailed teaching plans, and complete sets of training equipment, but has disadvantages such as boring, single type of PLC, and unsustainable training;

[0005] Self-study has the disadvantage that theory cannot be connected with practice;

[0006] Using the equipment in operation on site for training may cause abnormal operation of the equipment due to misoperation, and in severe cases, it will lead to shutdown;
