速度、精度、准时、价廉等术语常与条码扫描有联系。条码扫描在包装方面的应用正在扩大,其中最常用的如仓库存量、灌装流水线中容器的鉴别以及材料输送等。各种条码系统的共同点是都作为扫描条码的硬件。扫描的组成部分: 条码扫描的主要组成部分为:光电部分、信号整修及数据处理。光电部分用以将条码中的条子与空隙转换成随时间变化的电信号。这一功能部分包括:光源、光敏传感器及光学系统,该系统将光源聚焦成一个小点,作横跨符号而移动的扫描。
Terms of speed, accuracy, punctuality, cheapness and bar code scanning are often linked. The application of bar code scanning in packaging is expanding, with the most commonly used ones being the stock of containers, the identification of containers in filling lines, and material handling. Common to all barcode systems are the hardware used to scan bar codes. Scanning components: The main components of bar code scanning: photoelectric part of the signal repair and data processing. The photoelectric part is used to convert the slivers and voids in the bar code into electrical signals that change with time. This section includes: light sources, light sensors, and optics, which focus the light to a small spot and scan across the sign.
