Production line control system and control method thereof

Abstract

The invention provides a production line control system and a control method thereof. The production line control system comprises multiple control subsystems used for respectively controlling equipment corresponding to each control subsystem and an instruction distribution device used for distributing a normative instruction to a control subsystem, corresponding to the type of the normative instruction, in the multiple control subsystems according to the type of the normative instruction. Besides, the invention also provides a computer readable storage medium used for storing instructions which can be executed by a processor as well as computer equipment. By adopting the production line control system provided by the invention, accuracy, stability and portability of the production line control system can be enhanced, mass production of a flexible production line is facilitated, and the flexible production line also can have high availability.

Description

technical field [0001] The present invention generally relates to the technical field of intelligent control, and more specifically relates to a control system of a production line and a control method thereof. Background technique [0002] With the rapid development of the economy and the significant improvement of people's consumption level, the society's demand for product diversification, low manufacturing cost and short manufacturing cycle is becoming increasingly urgent, and the market needs more personalized and customized products with characteristics and meeting user requirements. . In order to cope with this change, a flexible manufacturing system or production line (Flexible Manufacturing System, FMS) based on various flexible manufacturing technologies has emerged. [0003] A flexible production line usually consists of processing equipment, auxiliary equipment, production line control system and related storage. figure 1 It is a typical flexible production lin...

Problems solved by technology

[0009] (1) The production line control system needs to have functions such as tool management, material management, dynamic production scheduling, and control of various hardware actions. In the traditional production line control system, so many functions are concentrated together, resulting in the volume of the control system Huge, not conducive to system stability and maintenance work

[0010] (2) In the traditional production line control system, when an instruction is sent to a specific device, if there is a problem with the device and the action cannot be completed normally, the subsequent actions of the production line may not be able to continue

[0011] (3) In the traditional production line control system, in order to control the action of the underlying hardware, the control system must issue instructions that the hardware can recognize. Usually, different models and different versions of equipment have different control instructions.

The result of this is that the production line control system needs to be changed according to the underlying hardware, and the control system is not portable and hardware-independent

In actual production, if the hardware layer changes, such as hardware upgrades, hardware system upgrades, or adding equipment, changes to the control system are required. Changing the control system is a large project, which greatly increases costs and is not conducive to this type of flexible production line. mass production
