Design of Control System of Fruit and Vegetable Packaging Machine Based on DSP

The work aims to design a control system of fruit and vegetable packaging machine, so as to improve the packaging quality and efficiency of fruit and vegetable products. A control system of fruit and vegetable packaging machine was designed based on DSP. The basic structure and technological process of fruit and vegetable packaging machine were introduced. On this basis, combined with the touch screen and DSP, the hardware structure of the control system was presented, including touch screen, DSP control module, temperature control module, IO signal acquisition module and servo drive system. At the same time, the software of motion control system of automatic fruit and vegetable packaging machine was developed, which could be divided into man-machine interface design and control system main program design. Finally, the control system was transplanted to the traditional fruit and vegetable packaging machine and studied experimentally. The experimental results showed that, the yield could reach 98%, the operation of the packaging machine was stable, and the packaging efficiency was high. The proposed control system of fruit and vegetable packaging machine based on DSP meets the requirements of packaging technology and has good overall performance.
