Network connection based teaching equipment adopting multiple numerical control systems and communication method

Abstract

The invention provides network connection based teaching equipment adopting multiple numerical control systems and a communication method. The equipment comprises an upper computer and a lower computer. The method is characterized in that the upper computer packs a G code file and an MCP instruction as the packed data and transmits the packed data to the lower computer; the lower computer receives the packed data, unpacks the packed data to obtain the unpacked data, then obtains the G code file and the MCP instruction from the unpacked data by calling the basis function of the conventional numerical control machine and uses the G code file and the MCP instruction to carry out instruction control on the machine; the lower computer packs the obtained machine state data, PLC state data and fault alarm data as the packed data and transmits the packed data to the upper computer; and the upper computer receives the packed data, unpacks the packed data to obtain the unpacked data and uses the unpacked data for displaying the machine state. Being adopted, the invention can add infinite sets of numerical control system programs without changing any hardware and dispense with purchasing multiple sets of numerical control machines equipped with different numerical control systems, thus greatly saving the equipment cost.

Description

technical field [0001] The invention relates to a multi-numerical control teaching system and a communication method used therein. Background technique [0002] CNC machine tools are more and more widely used in machining, but most of the teaching and training equipment used by schools and CNC machining training units are conventional CNC machine tools or computer simulation software. Conventional CNC machine tools are equipped with only one CNC system for one machine tool. Different CNC systems have different operation methods and programming instructions. If you want to teach multiple sets of CNC systems, you must purchase multiple machine tools and have enough There is a large space to place the machine tool; although the NC simulation software can simulate multiple sets of systems on the computer, but because it simulates the machining process of the machine tool through the display control buttons and processing graphics on the screen, the training effect is relatively ...

AI Technical Summary

Problems solved by technology

The teaching CNC machine tool uses hardware circuits to switch between control systems. The hardware circuits are expensive to manufacture and difficult to upgrade. When an upgrade is required, a new hardware circuit needs to be redesigned, which is time-consuming, laborious and expensive.
