目的 为了提高果蔬产品的包装质量和包装效率，设计一种果蔬包装机控制系统。方法 基于DSP设计一种果蔬包装机控制系统，介绍果蔬包装机的基本结构和工艺流程，在此基础上，结合触摸屏和DSP给出控制系统硬件结构，包括触摸屏、DSP控制模块、温度控制模块、IO信号采集模块以及伺服驱动系统等。同时开发全自动果蔬包装机运动控制系统软件，包括人机界面和控制系统主程序的设计。最后，将该控制系统移植到传统果蔬包装机，并进行实验研究。结果 实验结果表明，良品率能够达到98%，包装机运行稳定，包装效率高。结论 所述基于DSP的果蔬包装机控制系统，满足包装工艺要求，整体性能良好。

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.
