基于DSP与线阵CCD传感器的电子数粒机控制系统

摘要

In order to meet the requirements of speed and precision for pharmaceutical packaging machinery, the control system of electronic counting-machine was designed based on DSP and linear CCD sensor. The system consists of the master control module based on digital signal processor (DSP), the imaging module based on double CCD sensors, the data acquisition module based on complex programmable logic device (CPLD).The interface of man-machine communication based on the modbus protocol and the program of picking and counting are designed. Practice shows that the system is high in counting speed, stable and reliable in performance.%设计了基于DSP与线阵CCD传感器的电子数粒机,包括以DSP为核心的主控模块、以双线阵CCD传感器构成的成像模块及以CPLD为核心的数据采集模块.该系统具有计数、剔残功能及人性化的人机界面.实验证明,该系统数粒速度快、运行稳定可靠.
