Abstract

The invention relates to an assembly line scheduling system and method based on PLC and AI recognition results. In the system, a photographing input module photographs the appearance of a product and inputs a picture to an upper computer module; the upper computer module controls the output of a PLC control module according to a detection result of the appearance of the product; a sensor group module detects the position of the product on an assembly line, and position information is input to the PLC control module; the PLC control module controls the operation of a motor module; the motor module inputs qualified products and unqualified products to different areas on the assembly line based on output of the PLC control module, and separate scheduling is achieved. The PLC control based on an AI recognition result effectively solves the problems that the manual recognition speed is low and the automation degree of assembly line operation is low. Meanwhile, the PLC is matched with a sensor for use, so that to-be-detected products can enter and leave a shunting area, and the problem that an industrial assembly line structure is too complicated is solved.

Description

technical field [0001] The invention relates to a pipeline scheduling system and scheduling method based on PLC and AI recognition results, belonging to the technical fields of control science and engineering and pipeline industrial production. Background technique [0002] With the development of AI (Artificial Intelligence, artificial intelligence) technology, the industry welcomes the development opportunity of intelligent manufacturing. However, at present, most industrial enterprises do not have a deep understanding of the application potential of AI, and industrial big data also lacks appropriate analysis and processing methods after collection. Considering the opacity of AI technology and the complexity of industrial production sites, the practicability, reliability and replicability of industrial technology still need to be considered. [0003] The operation of industrial assembly line often uses PLC to participate in the control. PLC, also known as programmable lo...
