Description
技术领域
本实用新型涉及噪声消除且更特别地涉及用于条形码扫描仪的环境光闪烁噪声消除。
背景技术
一般而言，诸如紧凑式荧光灯（CFL）和发光二极管（LED）灯之类的节省光源近年来已经变得更加普遍。然而，用这些光源，使更多的工作区域经受具有高频闪烁的环境光。基于激光的条形码扫描仪可能由于此类闪烁光干扰而经历适当地运行方面的困难。
来自基于激光的条形码扫描仪附近的环境光的闪烁可以向条形码扫描仪的扫描光信号中引入噪声或干扰。例如，荧光灯具有高频电子镇流器，并且发光二极管（LED）灯具有高频驱动器。这些高频部件在条形码符号上生成脉冲照明。此脉冲照明可以作为光学噪声被条形码扫描仪接收。噪声可以引入假边沿检测，其可以导致条形码扫描电路进行的困难或不正确的条形码解码。
图1A和1B是从在信号分析测试期间获得的屏幕快照导出以确定来自环境光的噪声和对基于激光的条形码扫描设备的适当扫描过程的后续干扰的图表。图1A的图表10示出了从第一条形码扫描过程接收的信号。在第一过程中，当特定环境光被关掉时获得条形码扫描信号。图1B的图表12是从当环境光被开启时从另一条形码扫描过程接收的信号导出的。具体地，条形码扫描信号是使用Honeywell型号1200g激光扫描仪获得的，并且环境光是PhilipsLED台灯型号69195。如从在信号分析测试中获得的条形码扫描信号可以看到的，在条形码读取器附近的LED灯的存在创建使条形码不能被解码的此类噪声。
因此，存在一种需要，以用于使基于激光的条形码扫描仪或条形码读取器在某种类型的环境光源的高频闪烁照明附近适当地操作。
实用新型内容
因此，在一个方面，本实用新型涵盖一种条形码扫描设备，其包括光源、第一传感器、第二传感器以及噪声消除电路。光源被配置成发射光束。第一传感器被配置成检测指示反射离开条形码的光的第一光信号。反射光源自于光源且源自于在条形码扫描设备附近的至少一个环境光源。第二传感器被配置成检测指示源自于所述至少一个环境光源的光的第二光信号。噪声消除电路被配置成从第一和第二光信号获得噪声消除扫描信号。
在另一示例性实施例中，提供了一种激光扫描装置。激光扫描装置包括外壳、激光源、第一光电二极管、第二光电二极管以及噪声消除电路。激光源被配置成发射将跨条形码扫描的一束激光。第一光电二极管被设置在外壳中并被配置成检测指示反射离开条形码的至少激光的第一光信号。第二光电二极管被设置在第一光电二极管附近的外壳外面，并被配置成感测第二光信号。噪声消除电路被配置成从第一和第二光信号获得噪声消除扫描信号。第一和第二光电二极管被配置成接收源自于至少一个环境源的光。
在又一示例性实施例中，提供了一种噪声消除电路。该噪声消除电路包括至少一个光学传感器和差分放大器。所述至少一个光学传感器被配置成在第一级中检测第一光信号并在第二级中检测第二光信号。第一光信号包括激光扫描分量和噪声分量，并且第二光信号仅仅包括噪声分量。差分放大器被配置成从第一光信号减去第二光信号以从而从第一光信号去除噪声分量。该噪声分量对应于来自至少一个环境光源的环境光。差分放大器被配置成输出噪声消除扫描信号。

具体实施方式
本实用新型涵盖用于消除光信号、具体地由激光扫描仪获得的光信号的噪声分量的系统和方法。在本公开的某些实施例中，与激光扫描仪的常规光传感器相结合地使用一个或多个参考传感器。参考传感器被配置成仅检测来自不同于期望激光源的源的环境光。检测的环境光被从激光扫描信号减去以提供期望的噪声消除信号。在本公开的其它实施例中，噪声消除电路包括延迟线、采样和保持电路、滤波器及其它电部件以消除来自激光扫描信号的噪声分量。
根据示例性实施方式，图2是基于激光的条形码扫描仪14或条形码读取器的实施例的透视图。可将条形码扫描仪14称为逆系统扫描仪（retrosystemscanner）。本公开的实施例参考用于逆系统扫描仪的噪声消除，然而至少一个实施方式可以适用于非逆系统扫描仪，如下面更详细地解释的。
图3是设置在图2中所示的基于激光的条形码扫描仪14中的元件的实施例的剖视侧视图。图3的实施例的元件还可以适用于其它类型的逆系统扫描仪。在图3的实施例中，条形码扫描仪14包括外壳16、激光源18、第一反射镜20、第二反射镜22、抛物面集光器23、光传感器24、以及在外壳16的一侧中形成的窗口26。
激光源18被配置成发射光束28，其被反射离开第一反射镜20、通过抛物面集光器23中的开口、反射离开第二反射镜22、通过窗口26从外壳16离开、并被投射到条形码30上。可以以从而使得能够跨条形码30扫描光束28的这样的方式来移动反射镜22。光传感器24可以是光电二极管或其它适当的光感测设备，并被配置成检测来自光束28的光，其被反射离开条形码30、第二次反射离开第二反射镜22、并且反射离开抛物面集光器23并被其聚焦。在图3中，图示出光传感器24的侧视图。
图4A是图3中所示的光传感器24的前视图。在此传感器布置中，使用单个光传感器24来检测来自条形码30的光反射。光传感器24位于外壳16内以接收源自于激光源18的反射光。
图4B是根据本公开的讲授内容的以另一传感器布置而配置的一组传感器的前视图。图4B的此传感器布置包括设置在条形码读取器14的外壳16内的光传感器24。在本实施例中，参考传感器32被连接到外壳16并位于外壳16的内部或外面。参考传感器被定位成具有从光传感器24的一定偏移以远离扫描光束反射。然而，参考传感器32足够接近于光传感器24以收集被反射离开附近条形码30的环境光，其然后被反射离开第二反射镜22和抛物面集光器23。
参考传感器32可邻近于或接近于光传感器24定位，并且可位于光传感器24的任一侧。参考传感器32可以是类似于光传感器24的光传感器，并且可包括一个或多个光电二极管。特别地，在参考传感器32从光传感器24偏移的情况下，参考传感器32被配置成感测来自环境光源的环境光，并感测从条形码30反射的非常少的光（如果有的话）。
图4C是根据本公开的讲授内容的以又一传感器布置配置的另一组传感器的前视图。图4C的传感器布置包括设置在条形码读取器14的外壳16内的光传感器24，如上文所讨论的。另外，在传感器布置中包括第一和第二参考传感器32、34。第一和第二参考传感器32、34被连接到外壳16并可位于外壳16内部或外面。第一和第二参考传感器32、34被定位成具有从光传感器24的一定偏移以远离扫描光束反射。第一和第二参考传感器32、34收集从附近条形码30反射的环境光，其也被反射离开第二反射镜22和抛物面集光器23。
参考传感器32、34可在光传感器24的相对侧邻近于第一光传感器24定位。可将参考传感器32、34配置为光传感器，并且每个包括一个或多个光电二极管。参考传感器32、34被配置成感测来自不同于激光源18的源的环境光。
图5是噪声消除电路36的第一实施例的电路图，其可被包含在基于激光的条形码读取器14的外壳16内。可替换地将噪声消除电路36与条形码读取器14分开地设置在处理设备中。图5的实施例的噪声消除电路36包括第一光电二极管38、第二光电二极管40、运算放大器46、以及电阻器42、44和48。第一光电二极管38对应于通常被配置成感测从扫描条形码反射的光的光传感器（例如，光传感器24）。第二光电二极管40对应于根据本公开的讲授内容使用的一个或多个光传感器（例如，参考传感器32、34中的一个或两个）。第二光电二极管40因此被配置为用以感测环境光的参考。
运算放大器46被作为差分放大器布置在噪声消除电路36中，以用于从由第一光电二极管38接收的光信号减去由第二光电二极管40接收的光信号。第一光电二极管38不仅接收从条形码反射的光，而且也接收环境光。第二光电二极管40主要仅接收环境光。在Vout处输出的差分信号是被扫描的条形码信号，其中环境光噪声信号被去除。可以通过调节放大器46的偏置设置以实现精确的消除来对运算放大器46进行微调。
图6是根据本实用新型的要扫描的条形码50的视图。光束（例如，来自图3的光束28）被作为光斑52指引到条形码50上。光束沿着路径54基本上垂直于条形码50的条移动。图3和4中所示的光传感器24具有围绕光斑52的相对于条形码50的视场56。视场5可包括随着跨条形码50扫描光斑52而移动的条形码50上的基本上矩形或正方形感测区域。图4B中所示的参考传感器32也具有相对于条形码50的视场58。参考传感器32的视场58保持接近于或邻近于光传感器24的视场56并随着跨条形码50扫描光斑52而移动。
两个视场56、58之间的差别是第一视场56包括来自激光源18和来自施加在条形码50上的任何环境光的光反射的视图，而第二视场58包括仅来自施加在条形码50上的环境光的反射的视图。再次地，当从两个不同视场56、58获得的信号被施加于图5的噪声消除电路36中所示的差分放大器46时，环境光信号被消除并且仅激光信号保留。
图7是根据图4C中所示的传感器布置的条形码50的视图。如图6中所示的视场56和58在图7中是相同的，其与图4B和4C的光传感器24和参考传感器32相关联。然而，另外，第三传感器（例如，图4C中所示的参考传感器34）具有从视场58的视场56的另一侧的第三视场60。视场56、58以及60分别地对应于光传感器24、第一参考传感器32、以及第二参考传感器34的传感器布置。
视场58和60对应于仅用于感测环境光的传感器。可对环境光信号进行平均或组合以获得表示总环境光信号的单个信号。可以从从视场56获得的信号中减去此总环境光信号以消除环境光噪声分量。可以使用图5的噪声消除电路36或如下面更详细地解释的其它电路来执行减法过程。在这方面，可将图5中所示的光电二极管40配置为在图7中所示的视场58、60内接收光的两个光电二极管。
图8是第四传感器布置70的实施例的透视图。在图8的传感器布置70中，第一光电二极管72和第二光电二极管74被基本上相互垂直地布置。传感器布置70包括在反射镜76中间具有孔78的反射镜76。反射镜76和孔78可以是基本上矩形的，或者可具有任何其它适当形状。
反射离开条形码50的反射环境光82被指引到反射镜76。反射环境光82中的某些通过孔78辐射并被施加在第一光电二极管72上。同时，反射环境光82中的某些被反射离开反射镜76并被透镜80聚焦到第二光电二极管74上。另外，也被反射离开条形码50的反射激光84被指引到第一光电二极管72。可将孔78配置成使得其基本上允许所有反射激光84通过反射镜76至第一光电二极管72。如上所述，可将由第一和第二光电二极管72、74获得的两个信号应用于差分放大器（例如，放大器46）以从条形码扫描过程消除环境光的噪声。
图9是根据又一实施例的传感器布置86的视图。在本实施例中，传感器布置86包括基本上相互垂直地布置的第一光电二极管88和第二光电二极管90，类似于图8的实施例。然而，作为图8中示出的反射镜76的替代，图9的实施例包括插入在激光94的反射光束和环境光96的反射光束的路径中的光谱分光镜（beamsplitter）92。
光谱分光镜92被配置成在将环境光96的光束分离的同时使激光94的光束通过。激光94作为第一光束98通过光谱分光镜92。环境光96被相等地分离成通过光谱分光镜92的第二光束100以及被光谱分光镜92反射的第三光束102。第一和第二光束98、100被施加在第一光电二极管88上且第三光束102被施加在第二光电二极管90上。如上所述，可以将由第一和第二光电二极管88、90接收的信号施加于差分放大器以从由第一和第二光束98、100构成的信号消除来自第三光束102的光信号。由于分离光束100和102是基本上相同的，所以从差分放大器输出的信号将基本上仅仅等于表示激光反射的第一光束98。
图10是也在图6和7中示出的条形码50的视图。在图10中，条形码的视场对应于来自图8的传感器布置70的每个传感器的视场。来自光束28的光斑52被图8中所示的光电二极管72的视场56围绕。在图10中还示出周围视场106并且其表示反射离开孔78的所有侧面上的反射镜76并被照射到第二光电二极管74上的光。如所示，在内视场（即，视场56）和外视场（即，视场106）的周界之间可能存在小的空间。在此布置中，第二光电二极管74从第一光电二极管72的视场56的所有侧面接收环境光信号。
图11是第二噪声消除电路190的实施例的电路图。虽然可将在本公开中公开的电路中的许多配置成供在逆系统扫描仪中使用，诸如在设计方面类似于图2中所示的激光条形码扫描仪14的激光扫描仪，但是在非逆系统扫描仪中也可使用图11的电路190。
图11的噪声消除电路190包括两个运算放大器204和220。第一运算放大器204在电路190中被配置为用于从一个光信号减去另一个的差分放大器。第二运算放大器220在电路190中被配置为用于提供非反相放大信号的负反馈放大器。
噪声消除电路190还包括电阻器196、206、212、218、222以及226和电容器192、194、208、210、214、216、224以及228。噪声消除电路190还包括配置有激光滤光镜200的第一光电二极管198和第二光电二极管202。具有激光滤光镜200的第一光电二极管198接收具有包括被滤出的激光的频带的光信号。因此，第一光电二极管198获得除激光频率的频带之外的光的基本上所有频率。第二光电二极管202正常地接收光，包括激光频率和在激光频率的范围外面的频率。用两组信号，可以从由第二光电二极管202接收的光信号消除来自第一光电二极管198的环境噪声频率。
上文描述的图5—11针对其中利用至少两个光传感器或光电二极管来获得用于从环境光中减去噪声信号的差分信号的实施例。相对于以下描述，描述了针对利用一个光传感器的激光扫描仪的实施例。例如，下面描述的噪声消除过程可利用图3和4A中所示的单个光传感器24。
图12是根据利用一个光电二极管的实施例的噪声消除电路110的电路图。图12的噪声消除电路110包括可见光激光二极管112、光电二极管114、电阻器116、晶体管117、反相器（inverter）118、开关120、122，延迟线电路124、相移电路126、电阻器128、130、134以及运算放大器132。可将可见光激光二极管112配置为用于条形码读取器的激光源，诸如图3中所示的激光源18。
在操作中，向输入Vin施加低输入信号，其继而被施加到晶体管117的基极或栅极，从而使可见光激光二极管112关掉。因此，光电二极管114仅从环境光源接收光。低Vin信号被反相器118反相成高信号，其从而使开关120闭合。当开关120被闭合时，来自光电二极管114的信号被提供到延迟线电路124，其使信号延迟直至操作的下一级为止。此信号在本文中称为暗场信号，指定激光或可见光激光二极管112关闭的时间。
在操作的下一级期间，Vin信号为高，其使可见光激光二极管112打开。在这种情况下，光电二极管114接收来自环境源的光加来自可见光激光二极管112的光两者。高Vin信号使开关122闭合，从而将来自光电二极管114的组合光信号施加到相移电路126，其使信号的相位移位以与延迟信号匹配。这里，相移信号（即，包括组合光信号）被施加到差分放大器132的正输入，并且延迟信号（即，暗场信号）被施加到差分放大器132的负输入。差分放大器132的输出（即，Vout）是激光信号，其中环境噪声分量被消除。
根据暗场噪声消除电路的另一实施例，可用模数转换器和用于存储暗场信号的数字存储器件来替换图12中所示的延迟线电路124。在这种情况下相移电路126可能是不必要的。可将包括激光分量和环境光分量两者的第二光信号施加到差分放大器132的正输入，并且可以将存储的暗场信号在数模转换之后施加到差分放大器132的负输入。从第二信号减去环境噪声的延迟或存储信号分量以获得噪声消除激光信号。
图13是根据本实用新型的讲授内容的根据利用一个光电二极管的第二实施例的噪声消除电路140的电路图。图13的噪声消除电路140包括电阻器142、可见光激光二极管144、光电二极管146、晶体管147、反相器148、采样和保持电路150、152、电阻器154、156、160以及运算放大器158。再次地，可将可见光激光二极管144配置为图3中所示的激光源18。
噪声消除电路140的操作涉及到向输入Vin施加高频调制信号。调制信号引起晶体管147调制可见光激光二极管144以便以特定调制频率照亮光电二极管146。为了减少附加噪声，调制频率比激光扫描信号和环境闪烁噪声信号两者的频率高得多。例如，调制频率可为最高条形码扫描频率的频率的至少三倍。
当调制信号为低时，可见光激光二极管144关闭，并且第一采样和保持电路150被其中以从光电二极管146接收信号，其仅包括环境光。当调制信号为高时，可见光激光二极管144点亮，并且第二采样和保持电路152被启用以从光电二极管146接收信号，其包括激光和环境光两者。图13的噪声消除电路140还可包括具有采样和保持电路150、152的信号延迟线，并且可使用同步前置放大器来将采样和保持电路150、152的输出组合以用于使差分放大器158的输入处的单独的信号同步。差分放大器158减掉环境光分量，并且仅输出激光分量。
图14是根据利用一个光电二极管的另一实施例的噪声消除电路170的电路图。在图14中，噪声消除电路170包括光电二极管172、电阻器174、运算放大器176、电阻器178、陷波滤波器180、以及频率匹配电路182。噪声消除电路170是用于用具有窄带宽的陷波滤波器180对噪声分量进行滤波的有源滤波器电路。可以基于环境光的闪烁噪声的频率和激光条形码扫描元件的频率来选择滤波频率。在某些实施例中，可以使用超过一个频率滤波器，特别是如果环境光引入闪烁照明的超过一个频率的话。替换地，可以使用无源滤波电路来降低噪声消除电路170的成本。
根据本公开的讲授内容，可将其它电路用于噪声消除。在另一示例中，可以使用跳频技术（frequencyhoppingtechnique），其中激光源（例如，激光源18）通过不同频率的任意模式（pattern）来操作，使得一个频率下的噪声可仅影响激光扫描过程的小的无关紧要的部分。并且，可使用相移技术来解决现有技术的解码问题。将跳频和相移电路与诸如滤波和消除之类的其它噪声消除电路组合可以进一步改善闪烁干扰下的激光扫描仪解码性能。
因此，可以对当前激光条形码扫描仪进行修改以包括环境噪声消除功能以改善解码性能。修改可以包括向现有电路添加参考光电二极管或添加噪声消除电路。可以用定制的光学部件以及ASIC设计和开发来实现更高级的解决方案。
