摘　　要：烟草行业中,烟用滤棒的直径和圆度生产要求均很高,原机所采用气压流量测试方法,由于其测量精度偏低,并受多种环境因素制约,造成以此检测手段的滤棒直径在线控制得不到正常应用。研究了一种基于DSP的CCD光学滤棒直径检测系统及该系统的组成结构、测量原理,着重阐述了基于DSP数字信号处理器的CCD信号的数据采集、数据处理及形成CCD曲线的意义。In the tobacco industry,the production requirements for the diameter and roundness of cigarette filter rod are very high.Air flow test methods used in the original machine,due to its low measurement precision,and various constraint of environmental factors,is not used to implement the online control of the filter rod diameter. This paper introduces an optical CCD detecting system based on DSP,which is used to for the filter rod diameter defection. and briefly describes its structure and measuring principle,and the emphasis is put on the description of the CCD signal data acquisition,data processing and CCD curve formation based on DSP digital signal processor. In addition,the function of the CCD curve is illustrated. Field application shows that the method us useful.
