Description

TECHNICAL FIELD

[0001] The present application belongs to the field of industrial automation, and particularly relates to a top-down automatic production line decomposition method. BACKGROUND

[0002] The core content of industrial enterprise digitization is the digitization of automatic production lines. At present, the application and development of automatic production lines are developing rapidly. However, the construction of industrial automatic production lines involves multiple fields such as machinery, electrical, PLC, robot, computer software, and requires team collaboration, which increases the complexity and difficulty of the entire project. The traditional automatic production line system is still based on traditional industrial software / PLC / industrial robot tools as the core system, and cannot further empower the enterprise digitization. The specific manifestations are as follows: (1) The digitalization and automation projects of manufacturing industry generally have problems such as too long cycle, high cost, low efficiency, poor quality, and difficult maintenance. (2) The traditional industrial software / PLC / industrial robot system is backward. Since the modeling, simulation, design, programming, development, debugging, and upgrading processes are very complex, it is now impossible to meet the needs of modern digitization and automation. In addition, the complexity of the construction of industrial automatic production lines increases exponentially with the scale of the project, especially for large projects, which often cost hundreds of millions of yuan in project construction funds and take years to complete. At present, the competition in this industry is fierce, and the technology, quality, and user satisfaction of various companies are uneven. For a project, overtime work is usually required to meet the construction period, installation and debugging, and finally the quality of the project cannot be guaranteed.

[0003] The patent aims at the pain points of industrial automation production line design and construction, adopts a methodological approach instead of traditional automation design methods from the perspective of digitization, adopts a top-down approach, and adopts the method of digitization first and hardware later; system integration first and single module debugging later. Realize efficient and low-cost solution to production line design and construction problem. The top-down method is a systematic method compared with the traditional bottom-up method. For the construction of large and complex industrial production lines, the traditional method is usually used. That is, first install and debug the submodules and subunits, and then integrate them into components or segment units. The bottom-up method is to integrate continuously to form the final production line. Using this method, the entire production line cannot be analyzed and verified from the overall perspective at the beginning. If there is an error in a part, it can only be found in the integration stage, so this method has high trial and error cost for building production lines, resulting in high final cost and low efficiency. The top-down method adopted by the patent can help us clarify the system design target and grasp the overall situation, so as to avoid deviation. Secondly, and most importantly, the top-down method changes our method of building production lines. A large module is divided first, and then the module continues to use the top-down method. It is a process and method of gradual refinement. Finally, the top-down method has two application ideas in the design and construction of industrial automation production lines. The first is digitization first and hardware later; the second is system integration first and single module debugging later. During the project design process, the two ideas are usually combined to form an organic integration of digitization first and hardware later; system debugging first and single module debugging later.
