Interactive training platform based on real PLC and computer virtual elevator components

Abstract

An interactive training platform based on real PLC and computer virtual elevator components, including PLC, computer, single-chip microcomputer signal conversion transceiver module, training junction box; the computer is installed with PLC program development software, and virtual control training component units, virtual Elevator installation unit, virtual elevator running diagram unit software; the platform edits and runs the elevator program on the real PLC, and other elevator components are virtualized on the computer. The virtual components have the same position, status, and connection properties with the PLC terminals as the real ones; single-chip microcomputer signals The conversion transceiver module is connected with the computer and the PLC, so that the PLC terminal signal is synchronized with the status of the virtual elevator components; the training junction box has connection terminals, which correspond to the control terminals of the virtual elevator components, and can be used for PLC control wiring training. The platform can carry out PLC programming, and use virtual elevator components to simulate elevator operation, and complete various scheduled training projects. It has the advantages of small equipment investment and small equipment footprint.

Description

technical field [0001] The invention relates to the technical field of teaching and training platforms, in particular to an interactive training platform based on real PLC and computer virtual elevator components. Background technique [0002] Elevator is a kind of special electromechanical equipment that is widely used. In order to ensure the normal operation of elevators, there is a large demand for technical talents related to elevators. Many vocational colleges have increased the teaching and training related to elevator engineering. In teaching, the purpose of elevator training is mainly to master the following skills: master elevator structure and principle, control scheme design, electrical connection, PLC control program editing. [0003] Elevator training is a course with strong hands-on ability. Limited by various factors, the existing teaching elevator training platform has the following problems: First, the all-physical training platform has problems of large inv...

AI Technical Summary

Problems solved by technology

[0003] Elevator training is a course with strong hands-on ability. Limited by various factors, the existing teaching elevator training platform has the following problems: First, the all-physical training platform has problems of large investment and large volume of experimental equipment. Disadvantages, and the full physical training platform is affected by the technical limitations of the students and the structure of the equipment itself. Generally, after the training equipment is installed, the students cannot disassemble and change the wiring. Therefore, students often have only a half-knowledge of the training content. The structure and principle, electrical connection can not achieve a good training purpose; secondly, limited by factors such as training venues and construction costs, the number of sets of equipment in many laboratories is limited, so the number of students participating in the training each time is small , the corresponding students have less time to participate in the training, and the training effect is not good

Third, the existing complete virtual elevator training platform simulated based on computer-related application software, although it reduces the construction cost, increases the number of training equipment under the same area, and can provide support for more students' training at the same time, However, due to its technical limitations, students cannot directly edit and run PLC programs. Students lack real PLC programming training, and the training effect is not ideal. Fourth, the existing virtual experiment platform is generally through Siemens S7-PLCSIM simulation software. It can be realized by simulation, or through WinCC flexible monitoring software, or through computer programming such as VB6.0, but because the control signal input by the input terminal of the PLC must be a real electrical signal, the computer cannot directly write the input terminal signal of the PLC, so the above In the scheme, the computer software cannot directly simulate the switch signal and sensor signal of the elevator, and the PLC cannot write programs according to the real elevator action, which greatly reduces the effect of the students' practical training
