Description

红外线定位节点装置及系统 技术领域
本发明涉及一种无线信号发射装置及系统，特别涉及一种红外线定位节点装置及系统。
背景技术
随着无线网络技术的发展，人们希望借助于无线信号来识别物体并进行准确的定位。例如，在机场这样旅客比较集中且陌生的环境中，对方便、准确的定位的需求变得尤为迫切。现有技术中的室内定位，通常是运用定位节点装置发射无线信号对目标物体进行ID标识。理想状态是：一个定位节点装置对应一个ID。当一个接收端经过一个定位节点装置的投射区时，只会收到一个信号ID；当其经过另外一个定位节点装置时，就会收到另外一个定位节点装置的ID。目前广泛应用的节点定位装置通常包括信号发射管和电路板。例如专利号为200820049054.7所描述的ID标识装置，其发射的信号不受限制的向四周发射。当该装置被悬挂时，其发射的信号投射区域就会呈现如图1所示圆锥形。图1为传统的红外线定位节点装置的红外线投射区示意图。其中，定位节点装置A和B均悬挂在天花板上，它们各自形成一个圆锥形的红外线投射区。如图1可见，定位节点A和B的红外线投射区之间形成了较大区域的信号盲区。可以预见的是，当缩小A和B之间的距离，其间的信号盲区虽然会缩小，但定位节点A和B之间形成的圆锥形的红外线投射区会进行重叠，这样就形成了信号盲区和信号强弱不均匀的区域。为了准确的识别物体并进行精确定位，需要对红外线信号投射区域进行限定，从而解决信号弱、强度不均匀和信号方向性差的缺陷。
发明内容
本发明的目的是提供一种信号稳定、强度均匀且信号方向性好的红外线定位节点装置和系统。
根据本发明的一个方面，提供了一种红外线定位节点装置，包括：
具有多个侧面的反光杯，
用于与所述反光杯配合的红外线发射管，所述红外线发射管定位成使得：所述红外线发射管所发出的光线通过所述多个侧面中部分反光侧面反射后形成的夹角m的范围为0°≤m<180°。
根据本发明的一个方面，提供了一种红外线定位节点系统，包括多个 红外线定位节点装置，其中一部分红外线定位节点装置与另一部分红外线定位节点装置配置成两者的红外线发射方向彼此垂直。
本发明使红外线发射信号的范围在0°至180°范围内可控，使得发射的信号稳定且强度均匀。提高了红外发射管的光照利用率，降低了节点装置的耗电量。实现了红外光的均匀投射，有效的避免了单个节点的发射盲区和相邻节点间的信号干扰。

具体实施方式
下面结合附图对本发明作进一步详细的说明。
图2示意性地显示了本发明的一种实施方式的红外线定位节点装置图。如图所示，该装置包括反光杯1(其主体结构在外壳6内)、红外线发射管2、中心控点3、外壳4、供电接口5和升级接口6。
在本实施方式中，中心控点3可以是集成了包括电源、微处理器、无线模块和光敏元件的电路板。其可用于向上述红外线定位节点装置提供电源、接收信号、信号处理、发送信号(例如红外信号)等。具体的，电源可以与供电接口5连接。电源用于向红外线定位节点装置供电。微处理器可以与升级接口6连接。微处理器用于处理接收到的信号并可以对程序进行升级。由此，红外信号可以相互通信，且可以数据升级。这增加了该装置的实用性能、便利性和功能性。
该中心控点3上设有向所述光敏元件提供光照的透光孔，光敏元件通过上述透光孔对周围环境光进行感应，自动调节红外线发射管2发射红外线的强弱，提高了红外发射管的光照利用率，降低了红外线定位节点装置的耗电量。另外，外壳4可以呈盒型(也可以为其它适于加工的形状)，用于容纳反光杯1、红外线发射管2和中心控点3，其上并留有与供电接口5和升级接口6匹配的凹槽，和与反光杯1相匹配的矩形开口。外壳4上设 有供反光杯1安装不同角度的槽位或者小孔。反光杯1具有反射红外线的功能，其独特结构能够使反射的红外线在0°≤X＜180°的空间上均匀投射。
图3示意性地显示了本发明一种实施方式的反光杯1的结构图。如图所示，反光杯1的形状为直平行六面体(侧棱垂直于底面的平行六面体)，所述六面体包括上底面15、下底面16、第一反光侧面11、第二反光侧面12、第三透光侧面13、第四侧面14和红外线发射管2。其中：上底面15可以是平行四边形。下底面16也可以是平行四边形。邻接的第一反光侧面11和第二反光侧面12可以形成第一夹角β。第三透光侧面13的形状可以是矩形，其可以与第一反光侧面11面对且与第二反光侧面12邻接。第四侧面14的形状可以是矩形的，其可以分别与第一反光侧面11和第三透光侧面13邻接。用于与所述反光杯1配合的红外线发射管2的照射范围由第一边缘光线和第二边缘光线形成的第二夹角γ确定，所述红外线发射管2定位成使得：所述第一边缘光线照射所述第一反光侧面11并形成第一入射角α1，所述第二边缘光线照射所述第二反光侧面12并形成第二入射角α2，所述α2为180°+α1-β-γ；所述第一边缘光线经所述第一反光侧面反射出的第一反射光线与所述第二边缘光线经所述第二反光侧面反射出的第二反射光线之间的反射夹角m为360°-2β-γ，其中，
所述第一入射角α1<90°；
所述第二入射角α2<90°；
所述反射夹角0°≤m<180°；
根据平面图形的基本特性(例如三角形的三个角之和为180°，四边形的四个角之和为360°)可推导出下列各角度的表达式：
m＝180°-(180°-γ-180°-2α1)-[180°-2*(360°-γ-(180°-α1)-β]＝360°-2β-γ
m＝180°-(180°-2α2)-[180°-γ-(180°-2α1)]＝2(α2-α1)+γ
β＝360°-α2-γ-(180°-α1)＝180°-α2-γ+α1
α2＝360°-β-γ-(180°-α1)＝180°+α1-β-γ
通过上述公开的反光杯底部与红外线发射管配合安装方法，使反射的红外线在0°≤X＜180°的空间上均匀投射。
通过实验和计算，对反光杯进行如下两种方式的特殊设置时，可以使得反射的红外线在90°的空间上均匀投射，形成了长方体红外线光柱。
方式一：上述第一夹角β为112.5°,上述第二夹角γ为45°，上述第一入 射角α1为45°，上述第二入射角为67.5°。
方式二：上述第一夹角β为90°，所述第二夹角γ为90°，所述第一入射角α1为67.5°，所述第二入射角为67.5°。
按上述方式设置反光杯时，所述第一边缘光线和第二边缘光线经所述第一反光侧面和第二反光侧面反射后形成的所述第一反射线和第二反射线的形成的角度为90°的长方体红外线光柱。上述红外线定位节点装置结构，使得投射的红外线光柱为长方体，减少了信号盲区，使得信号强度均匀、稳定。
另外，需要说明的是，本实施例中采用了一根红外线发射管，是为了示意性的反映光线折射效果，对本领域的技术人员来说，为了增加红外红信号强度，可以在外壳内设置多个红外线发射管，具体可以设于反光杯的上部、下部或者设于反光杯的内部。
由此，通过在上述红外线定位节点装置中独特设置反光杯，使红外线发射信号的方向可控，使得信号稳定且强度均匀，提高了红外发射管的光照利用率，降低了节点装置的耗电量，实现了红外光的均匀投射，有效的避免了单个节点的发射盲区和相邻节点间的信号干扰。
在一些实施方式中，所述反光杯1的形状为直平行六面体，所述六面体包括平行四边形的上底面15、平行四边形的下底面16和矩形的第四侧面14，所述第四侧面14分别与所述第一反光侧面11和第三透光侧面13邻接。这种设计方式设计简单，加工方便。
在一些实施方式中，所述上底面15、下底面16和第四侧面14涂覆有吸光材料，在所述第四侧面14上，或者在邻近所述第四侧面14的下底面16上，设有至少一个用于容纳所述红外线发射管的孔。所述红外线发射管的灯泡安装在与其大小和数量匹配的孔内。上述红外线定位节点装置结构，使得红外线发射管直接射向反射面，红外线散射损耗小，反射效果好。
在一些实施方式中，通过所述红外线发射管和反光杯有多种配合安装的方式：所述上底面15和第四侧面14均为吸光面，所述下底面16为透光面，反光杯外侧为中心控点，所述红外线发射管与所述中心控点连接且位于所述下底面16的下方。或者将所述上底面15、下底面16均为吸光面，所述第四侧面14为透光面，所述红外线发射管与所述中心控点连接且位于所述第四侧面外侧。上述两种红外线定位节点装置结构，使得红外线发射管安装在反射杯的外部，无需在反光杯上打孔，不仅工艺简单，还便于安装。
在一些实施方式中，所述反光杯的主体为透光材料制成的实体结构。此种结构便于在各个侧面按需要涂覆吸光或者反射材料，不仅使得工艺简 单，而且质量可靠。对本领域的技术人员来说，可以对红外线发射管安装在反射杯的外部，例如安装在反射杯的上部、下部或者第四侧面的外侧，只需相应的改变侧面的吸光材质或者透光材质，使得所述红外线发射管发射的红外线入射面和红外线经过反射后射出反射杯的矩形的第三透光侧面13为透光材质，第一反射面11和所述第二反射面12为反光材质，其它的面外围吸光材质即可。
本发明红外线定位节点装置设计成盒体形状，这种形状更加便于安装。由多个上述红外线定位节点装置构成的红外线定位节点系统，在其安装时，通过不同的安装方式带来了不同的技术效果。
例如，将其中一部分红外线定位节点装置与另一部分红外线定位节点装置配置成两者的红外线发射方向彼此垂直，或者将一部分红外线定位节点装置中的每个红外线定位节点装置之间的距离设置成使得各个红外线定位节点装置的照射区域没有重叠，所述另一部分红外线定位节点装置之间的距离设置成使得各个红外线定位节点装置的照射区域没有重叠。
上面所例举的六面体的反射杯，只是示意性地反应红外线入射和反射的效果，同时各个角度计算起来也相对简单，对本领域的技术人员来说，可以将反射杯的形状做各种变化，例如，将上底面和下底面设置为梯形、五边形等形状，侧面可以设置为多个，只需符合如下要求即可：所述红外线发射管所发出的光线通过所述多个侧面中部分反光侧面反射后形成的夹角m的范围为0°≤m<180°。
在一些实施方式中，所述反光杯的多个侧面可以包括：形成第一夹角β的邻接的第一反光侧面和第二反光侧面；以及与所述第一反光侧面面对且与所述第二反光侧面邻接的矩形的第三透光侧面。
图4至图7示意性的显示了红外线定位节点装置(或系统)一些典型的安装方式。
图4显示的是将红外线定位节点装置安装在垂直的基准面上。图5显示的是图4方式安装的立体示意图。如图5所示，红外线定位节点系统(包括红外线定位节点装置A、B)安装在室内(例如机场候机室内)的墙壁上。
在使用时，它们分别在机场候机室内形成了立体的红外线信号投射区，该立体的红外线信号投射区在墙壁和地面分别形成了矩形的投射截面。红外线定位节点A、B还可以通过其内的微处理器和无线模块来进行互通信息，使得该装置功能更加强大、使用更加方便。另外，可以通过安装若干个节点来实现大跨度的定位识别。也就是说通过变更节点的个数来将图示中的投射宽度d进行控制。通过这种典型的批量安装方式，可以实现信号强度均匀，接收稳定可靠，使得在发射范围内大幅度的减少了信号的盲区。
在本实施方式中，红外线定位节点装置A、B平行设置，这种设置方式可以节省红外线定位节点装置的个数。
为了进一步减少了信号的盲区，还可以将一部分红外线定位节点装置与另一部分红外线定位节点装置配置成两者的红外线发射方向彼此垂直。所述一部分红外线定位节点装置中的每个红外线定位节点装置之间的距离设置成使得各个红外线定位节点装置的照射区域没有重叠，所述另一部分红外线定位节点装置之间的距离设置成使得各个红外线定位节点装置的照射区域没有重叠。
本发明公开的红外线定位节点装置和系统，其中反光杯具有反射红外线的功能，其独特结构能够使发射的红外光在空间上均匀投射，所述节点壳体具有反光杯最佳安装角度的槽位。
所述节点正常安装时，从节点内发射出来的红外光，其截面呈矩形，即具有水平向前和竖直向下范围内的红外光照射，强度均匀，接收稳定可靠，从而使得信号接收在发射范围内无死角盲区。同时节点内的光敏元件可以通过对周围环境光的感应，自动调节红外光发射的强弱。
图6显示的是将红外线定位节点装置安装在水平的基准面上。例如，将其安装在机场候机室的天花板或者地面上。因为本发明红外线定位节点装置的反光杯和发光口的特殊设计，使得发出的红外线截面呈矩形，即具有水平向前和竖直向下范围内的红外光照射，强度均匀，接收稳定可靠，使得在红外辐射发射范围内最大程度的减少了信号的盲区。
图7显示的是根据图4和图6这两种安装方式混合安装方式，即，垂直和水平混合安装方式。如图7所示，通过这种垂直和水平混合安装方式，在单个外线定位节点装置信号接收效果非常好的基础上信号几乎没有盲区，再次形成了矩形截面覆盖的红外线强度均匀的红外线投射区，在此投射区内完全消除了信号盲区。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
