Embedded control system for carton proofing machine and control method thereof

Abstract

The invention provides an embedded control system for a carton proofing machine and a control method thereof. The control system comprises an embedded microprocessor module and a motion control module which are connected through a data bus and a control bus, wherein a dual-core CPU chip is used as a core of the microprocessor module; and the motion control module is used for carrying out pulse output control by using a fine-interpolation motion control module. The control method provided by the invention comprises the following steps of: (1) inputting an image file or a code-processing file to be processed, recognizing a graphic profile, planing a locus, preprocessing the speed or converting processing codes; (2) carrying out crude interpolation operation; and (3) carrying out fine interpolation operation, outputting control to a stepping or servo system to control the action of an execution unit so as to finish the cutting of a carton pattern to be designed. The invention has the advantages of small size, low hardware cost, high real-time property and stability of system operation, good reliability and expansibility and low system power consumption and is suitable for the development needs of an electromechanical product for the embedded control system.

Description

technical field [0001] The invention belongs to the technical field of carton manufacturing automatic control, in particular to an embedded control system and a control method for controlling machine tools to complete carton proofing. Background technique [0002] In the carton proofing control system, the motion controller plays the same role as the human brain, and its performance greatly affects the quality of the carton proofing effect. At present, the diversification of cartons makes the graphics that need to be processed more and more Complicated and increasingly difficult. Therefore, improving the performance of the control system while reducing its price is the key. In the development process of motion controllers, motion control platforms with single-chip microcomputers, application-specific chips (ASICs), DSPs, and FPGAs as core processors have emerged. Among them, the main motion controllers currently on the market are based on "PC + motion control card" The mot...

Problems solved by technology

But this method has great limitations in structure and performance:

[0003] First, the motion control card cannot be separated from the computer bus, and needs to be inserted into the PCI or ISA slot of the computer motherboard. Therefore, a PC must be configured as the upper computer for each specific application, which undoubtedly affects the size, cost and operating environment of the equipment. There are certain limitations, it is difficult to operate independently and miniaturize

[0004] Second, because the general-purpose industrial PC platform is used, the hardware cannot be tailored. For many occasions, many functions on the PC are not used, and the user still has to pay the cost

Because it is impossible to tailor the system software and hardware according to the characteristics of the motion control system, the use of general-purpose industrial PCs cannot well build an embedded motion control platform
