Description

可调制光场范围和具备高效能发射的通行传感器 技术领域
本发明涉及一种通行传感器，特别是涉及一种可调制光场范围和具备高效能发射的通行传感器。
背景技术
自动通行门一般用于某些需要人员或载具经常出入的场合(例如仓库、通行隔间、银行、商场、或公司行号等)，通过门顶部设置的红外光线通行传感器，感应到有人或载具需要进入或者离开，可驱动电机使自动卷门或自动门扇打开，人员或载具离开后感应器不受到感应，自动卷门或自动门扇即可自行回复关闭。然而现有的红外线通行传感器，其发射出的红外线投射光场范围大多呈固定状态，并无法因应安装场所通行范围的不同而灵活的加以调整变化，因此经常会在有不同通行范围的需求时，必须另行更换不同投射光场范围的感应器，造成使用上的不便；这在自动上下卷门所使用的红外线通行传感器也具有同样的问题。此外，当现有的光线传感器上；由多个光发射元件所发射出的多道光束投射到发射凸透镜时，并无法有效确保各LED投射的光束的光轴能准确投射到该凸透镜的镜心，致使各LED投射的光束不能均匀地覆盖到该凸透镜的镜片上，使得投射到感应范围的光场能量并不均匀，导致光场范围内反射回到传感器的光强度亦不均匀。
发明内容
为了解决上述的技术问题，本发明提供一种可调制光场范围和具备高效能发射的通行传感器，用以控制自动通行门的开启或关闭，该通行传感器包括：至少一光场调制电路，该光场调制电路包含至少一个光场开关、多个电子开关元件；以及一感应镜头，该感应镜头包括一光发射部位以及相邻的至少一光接收部位，该光发射部位包含多个光发射单元和一发射凸透镜片，该光接收部位包含多个光接收单元以及由多个凸透镜组成的一光接收凸透镜组；其中该光场调制电路内的该光场开关，能控制该多个电子开关元件，调制所述多个光发射单元的开启或关闭，以调制投射不同角度的光束到该发射凸透镜片，再由该发射凸透镜片依光学原理将光束辐射到该自动通行门前所需要的通行范围形成一光场；而在该通行范围内的光场有外来物体介入时，将会反射光线到该光接收部 位内的该光接收凸透镜片组，使该光线依光学原理聚焦到该光接收单元，再借该光接收单元具备的光电信号转换功能将该反射光转换成电子信号，经一信号处理系统处理后输出一能够控制自动通行门开、关的信号。
本发明的有益效果在于，本发明所提供的可调制光场范围和具备高效能发射的通行传感器，包括一光场调制电路，借由该光场调制电路和感应镜头内的光发射模块电连接，即可通过该光场调制电路中的光场开关，控制该光发射模块中各光发射单元的光线的发射；使得本发明的通行传感器发射范围呈可调制的型态，即该通行光场范围的大小得以对应该自动通行门现场的需求予以调制，可便利于安装时的灵活调整及使用。更进一步地，因为光发射模块中设置有多数各不同角度的光发射独立电路板，且各该光发射独立电路板上光发射单元的光束的光轴，能够以不同角度投向发射凸透镜片的镜心，并与发射凸透镜片的光轴接近光学同轴关系，因此所述多个发射单元的光束均能高效地投射到自动通行门的光场范围。
依据本发明上述的可调制光场范围和具备高效能发射的通行传感器，其中该感应镜头的该光发射模块更可以包含一发射承载座及一光发射载体；该发射承载座包含一发射座体，该发射座体设有多个不同角度的座体安装面相互衔接，该光发射载体包含一光发射组合电路板，该光发射组合电路板，由一平板的电路板对应所述多个座体安装面相互衔接的位置切割多条V形槽及沟槽，借此将该平板的电路板进行裂折，折裂后对应该座体安装面的所述多个角度形成相对应角度的光发射组合电路板，因此类似由多个区块光发射独立电路板电连接成一内含有多个对应角度的光发射组合电路板，该光发射组合电路板的正面电性装置所述多个光发射单元，再以不同角度面向该发射凸透镜的镜心，背面则为光发射组合电路板安装面，并各别以相互对应的角度结合在所述多个发射座体的座体安装面，使得电性装置在光发射组合电路板的所述多个光发射单元所发射光束的光轴，可以接近光学同轴的关系投射向该发射凸透镜的镜心，让所述多个光束能够均匀地覆盖在该发射凸透镜上。
为使能更进一步了解本发明的特征及技术内容，请参阅以下有关本发明的详细说明与图式，然而所提供的图式仅用于提供参考与说明，并非用来对本发明加以限制。

如图4所示，可见光发射模块02包含一可见光发射载体210及一可见光承载座220。可见光发射载体210包含多个可见光发射单元211及至少一个可见光独立电路板212，所述多个可见光发射单元211分别电性设置于该可见光独立电路板212的正面；该可见光承载座220具有一可见光座体222，该可见光座体222上设有多个可见光座体安装面223，可见光座体安装面223与可见光独立电路板212背面的角度相互对应和贴合；由于所述多个可见光发射单元211分别电性装置于所述多个可见光独立电路板212，并设置于该可见光承载座220上，使得所述多个可见光发射单元211所发射的光束的光轴，均能朝向可见光发射凸透镜组402的镜心，因此投射的可见光束能够均匀地覆盖于该可见光发射凸透镜组402上。因两者相对应的关系以及依光学原理产生的可见光发射光轴Kl(如图5)能够高效能地将可见光辐射到可见光范围K(如图11、图12、图13、图14、图15)投射到接近自动通行门前缘处。
至少一个以上可见光独立电路板应彼此电连接即可组成一可见光组合电路板，所述多个可见光组合电路板可为一平板结构型态，且该电路板的背面，对应上述多个独立个体的可见光独立电路板212的相同位置，可以如光发射组合电路板一般，由多条V形槽折裂成多个相对应的可见光独立电路板区块，在维持彼此电连接的条件下相对应安装贴合在各可见光座体安装面223上。
请参阅图4，在本实施例中，所述多个光发射单元111排列成上、中、下三列；设置于上列的三个光发射单元1l1发射出右上光轴u-r、中上光轴u-c、左上光轴u-1，设置于中列的三个光发射单元111发射出光轴右中m-r、正中光轴m-c、左中光轴m-1，设置于下列的三个光发射单元111发射出右下光轴d-r、中下光轴d-c、左下光轴d-1；其中的右上光轴u-r、中上光轴u-c、左上光轴u-1、右中光轴m-r、光正中轴m-c、左中光轴m-1、右下光轴 d-r、中下光轴d-c及左下光轴d-1，和该发射凸透镜501形成光学同轴的关系，因此所述多个光发射单元111发射的光束能均匀地覆盖到该发射凸透镜501的镜片上。光发射模块01内光发射单元111的发射光束，均能以不同角度投向发射凸透镜501的镜心，并因光学原理投射组合成通行感应光场范围。
请参阅图11，该通行传感器10设置于自动通行门的门口处，并由该光场开关701选择投射光场范围，让该光发射单元111投射在自动门前方形成广、近位置的光场投射范围G，且该光广接收反射范围I和光近接收反射范围H用以接收光场投射范围G全区的反射光线。
请参阅图12，该通行传感器10设置于自动通行门的门口处，并由该光场开关701选择投射光场范围，让该光发射单元111投射在自动门11前方位置形成光场投射范围G，且该光广接收反射范围I用以接收光场投射范围G全区范围的反射光线。
请参阅图13，光发射单元111和可见光发射单元211，分别投射在自动门11前缘光发射范围J和可见光范围K的位置，近接收凸透镜组401用以接收靠近自动门11前缘光发射范围J的近接收光轴Hl；如有外来物进入光近接收反射范围H位置内，光场能量将有所改变，进而经由控制回路使自动门11开启。
请参阅图14，该通行传感器10设置于自动门11，侧边光发射单元111和可见光发射单元211，分别投射在自动门11侧边前缘处的光近发射范围J和可见光范围K的位置，近接收凸透镜组401用以接收靠近自动门11侧边前缘的光近发射范围J的反射光线和侧边接收光轴Hs1；当自动门11进行开门运转时，如有外来物接近自动门11侧边开门运转范围，该光近接收部位04对接收到的侧边接收光轴Hs1，经由信号处理系统控制自动门11即时停止或减速反应，以保持安全运转。
请参阅图15，该通行传感器10设置于自动卷门12门口处，由光场开关701(未标示于图15)选择投射光场范围，光发射单元111投射在自动卷门12前方位置的光场投射范围G，该光广接收反射范围I即用以接收光场投射范围G全区范围的反射光线。
可见光发射单元211对应投射在可见光发射凸透镜组402，再依光学原理投射可见光范围K在靠近门的前缘端的位置，可见光的光场位置，即可对应显示光近发射范围J和光近接收反射范围H在门前缘的相关位置。
本发明的有益效果在于，本发明所提供的可调制光场范围和具备高效能发射的通行传感器包括多个光发射单元、至少一发射凸透镜、至少一光接收单元及至少一接收凸透镜。所述多个光发射单元以多个呈阵列排列，即所述多个光发射单元可排列成至少一 列，亦可排列成两列、三列或四列等多列，当所述多个光发射单元只有一列时，该列包含多个光发射单元，光发射单元呈两列或两列以上时，则每一列至少具有一个光发射单元，所述多个光发射单元电连接到光场开关控制单元内的电子开关元件和光场开关，进而控制所述多个光发射单元是否投射光束，且所述多个光发射单元所发射的光束的光轴，均分别和发射凸透镜的光轴接近光学同轴，使得所投射的光束都能均匀地覆盖于发射凸透镜上，因此光发射单元以不同角度朝该发射凸透镜所投射的光束，都能够高效能地均匀辐射到感应范围的光场上；而且发射范围通过预设的光场开关控制形成可调制的型态，能灵活的加以调整变化，使得通行光场范围得以对应自动通行门装设现场的需求加以调制，能便利于安装时的灵活调整及使用。
以上所公开的内容，仅为本发明优选的可行实施例，并非因此局限本发明的申请权利要求范围，所以举凡运用本发明前揭说明书及图式内容所做的等效技术变化，均应包含于本发明申请权利要求范围内。
