Problems solved by technology

For example, importing the graphics generated by AutoCAD software into the PLC, and driving two servo motors through the PLC can easily meet the needs of plane motion control, but the communication speed of this solution is slow, which seriously affects the normal production work. Therefore, it is necessary to improve on this technique

Abstract

The invention discloses a drawing control method and system, and the method comprises the steps: enabling an original CAD drawing file and a preset PLC control parameter to be converted into a first CAD file in a specific data format, enabling an HMI to analyze the first CAD file, obtaining a preset PLC control parameter and a path coordinate set, and enabling the preset PLC control parameter andthe path coordinate set to pass through a specific HMI- PLC protocol sends the data to the PLC, so that the PLC controls the drawing motion mechanism to complete interpolation drawing according to preset PLC control parameters and the path coordinate set, the technical problem that in the prior art, a drawing control method is low in communication speed is solved, rapid data communication is achieved, and the safety of data transmission is high.

Description

technical field [0001] The invention relates to the field of drawing, in particular to a drawing control method and system. Background technique [0002] PLC: Programmable Logic Controller. [0003] HMI is the abbreviation of Human Machine Interface, "human-machine interface", also called human-machine interface, also refers to human-computer interaction equipment. Human-computer interface (also known as user interface or user interface) is a medium for interaction and information exchange between the system and users, and it realizes the conversion between the internal form of information and the form acceptable to humans. [0004] HMI consists of hardware and software, refer to figure 1 , figure 1 It is a schematic diagram of the hardware part of HMI. The hardware part includes processor, display unit, input unit, communication interface, data storage unit, etc. The performance of the processor determines the performance of the HMI product and is the core unit of the HM...
