A PC-based control method for high-speed sorting line integrating data reading, image processing, sequence logic control, communication, and HMI

What is it about?

The vision-based automatic systems for in-line detection, identification, and separation are widely used in industry, and it is difficult for such systems to achieve simplified structure, high-speed, high-efficiency, and integrated coordinated control.An automatic control system was proposed integrating data reading, image processing, sequential logic control, communication and human-machine interface (HMI) based on personal computer (PC) with general operating system (OS).The multi-core multi-thread (MCMT) technology has been utilized, in which the optimized process-thread settings (OPTS), first-in first-out (FIFO) stacker, variable sharing between threads and encoder position synchronization were employed.The results showed that the average scan cycle of sequential logic control was only 15 μs.The presented control system has the advantages of near real-time, high-speed, high-efficiency, low cost, easy reconstruction, capable of manage and control integration, and has good practical application value.
