摘要:
A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edge of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
摘要(中):
扫描仪确定目标是否是条形码符号,如果是,则确定该符号是否为一维。 对于二维符号,扫描仪将扫描图案与符号对齐,并将扫描图案展开为仅到达符号的顶部和底部边缘,而不是超出。 扫描仪还有一个微处理器控制扫描引擎,它使用一个线圈驱动扫描元件并从扫描元件拾取反馈信号。 脉宽调制调节器还可以为驱动线圈提供快速高效的操作。 扫描引擎也可以被设计为产生穿过目标的图案,并且扫描引擎的强大接口允许解码和控制逻辑与扫描引擎独立并且独立于扫描引擎而高效地工作。
