PLC-control-based virtual simulation experiment method and system for fireworks sorting assembly line

Abstract

The invention discloses a PLC-control-based virtual simulation experiment method and system for fireworks sorting assembly line. The virtual simulation experiment method comprises: step A, establishing a virtual simulation environment for a fireworks sorting assembly line; to be specific, carrying out modeling on a working unit of the fireworks sorting assembly line and carrying out animation simulation on all procedures involved in the working process of the fireworks sorting assembly line; step B, establishing a PLC control system; step C, establishing communication between eh virtual simulation environment of the fireworks sorting assembly line and the PLC control system; and step D, carrying out debugging. According to the invention, the risk of dangerous explosion of the actual fireworks sorting assembly line is eliminated and the needs of actual PLC engineering training by students can be satisfied; the optimal control strategy and plan of the fireworks sorting assembly line canbe determined quickly during the fireworks sorting assembly line modification process; the dependence on the OPC service program of the manufacturer is eliminated; the PLC device from any manufacturercan be selected; and a phenomenon of carrying out designing and debugging again because of changing of a PLC mode or a manufacture factory is avoided.

Description

technical field [0001] The invention belongs to the technical field of virtual simulation experiments controlled by PLC, in particular to a method and system for virtual simulation experiments of fireworks sorting lines based on PLC control. Background technique [0002] The automatic sorting function of the fireworks sorting line can effectively reduce labor costs and improve sorting efficiency. However, the control of the fireworks sorting line has extremely high safety requirements. If it is directly developed by students, there is a high possibility of danger. [0003] For this reason, the inventor thought of using virtual simulation technology and PLC (programmable controller) technology to build a realistic fireworks sorting line simulation system, and organically combined with the actual PLC, so that the designed PLC fireworks sorting line control system can be controlled Conduct tests to verify the reliability and stability of the PLC control program to avoid high-ri...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that these methods in the prior art all rely on the OPC service technical support of the manufacturer. When changing the PLC model or the manufacturer, the original program may need to be redesigned and debugged because there is no corresponding OPC technical support. the inconvenience

In addition, since this method is completely based on the communication protocol, students lack the connection and control experience of real equipment when doing experiments
