Standards-Based Grading

Code quality grading software for fixed-mount barcode readers

根据标准分级 (SBG) 是一项软件功能,可在指定 DataMan 固定式读码器上预载或激活,从而为一维条码和二维码的质量分级。SBG 使用和 DataMan 验证器相同的分级算法、标定流程和软件用户界面,但未包含国际标准化组织 (ISO) 规范中要求的固定角度照明。SBG 适用于现有条码质量软件(例如流程控制指标 (PCM))不够可靠,并且无 ISO 合规要求或无法实现的情况。

Why Standards-Based Grading?

An increasing number of industries require compliance to ISO or industry application guidelines that can only be met with ISO-compliant barcode verifiers. However, not all applications are able to use ISO-compliant verification due to mounting restrictions or barcode placement.

SBG is the closest way to achieve reliable and repeatable barcode diagnostic results similar to verification without conforming to specific lighting angles, working distances, or mounting restrictions. With SBG, the reader can be calibrated to unify the camera’s measurement of reflectivity levels and all ISO quality parameters are reported.

Unlike SBG, PCM does not have a calibration process, follow the ISO grading algorithm requirements, or report every quality parameter. While PCM results can provide a good idea of code quality, the results can also vary significantly between setups and hardware used.

自动生成条码质量报告

SBG 软件平台可提供直观的诊断信息,有助于发现一次性或趋势性的条码质量问题。使用 ISO 分级算法测量多个符号特定质量参数,然后为条码分配一个整体分级。这些参数可评估多个影响读码器识别和解码条码能力的因素。
