Abstract

The invention discloses a drawing control method and system. By converting the original CAD drawing file and preset PLC control parameters into a first CAD file in a specific data format, HMI analyzes the first CAD file to obtain preset PLC control parameters and path coordinates. Collect and send it to the PLC through a specific HMI-PLC protocol, so that the PLC can control the drawing motion mechanism according to the preset PLC control parameters and path coordinates to complete the interpolation drawing, and overcome the slow communication speed of the drawing control method in the prior art Technical issues, realizing fast data communication, and high security of data transmission.

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...
