Description

用于全高式屏蔽门的安全保护装置 技术领域
本发明属于自动门传感器技术领域，具体涉及一种用于全高式屏蔽门的安全保护装置。
背景技术
近年来，随着城市化进程的不断进步，城市交通压力越来越大，导致越来越多的城市选择采用轨道交通方式进行必要的交通压力疏解。其中地铁就是一种常用的城市轨道交通工具。与传统火车、动车、高铁等轨道交通运载工具相比，由于地铁常修建于地下，且乘客往往在列车进站前就已经在月台等候，且地铁乘客人数往往很多，很容易由于月台拥挤从而引发安全事故。因此，在地铁的月台上，及部分动车、高铁月台上，需要配备具有安全防护功能的屏蔽门。常见的地铁屏蔽门根据其门高，分为超过一般人群身高高度的全高式屏蔽门和一般高度在1米至1.5米的半高式屏蔽门。根据需要，全高式屏蔽门有的采用封闭式结构，即屏蔽门闭合时，月台和轨道之间完全分开。有的也采用非封闭结构，即屏蔽门顶端与地铁月台的顶部设有一透气间隔。
地铁在方便人们出行的同时，也带来了一些安全隐患。为了确保行车安全，列车和屏蔽门必须满足一定的限界要求，造成关闭后的屏蔽门和列车门之间存在一定的间隙。乘客一旦滞留在该区域，列车启动后会导致重大伤人事故。
为了对防止上述情况的出现，现有技术通常是采取在该间隙空间内加装安全防护装置，但是由于微波传感器容易受到行人或列车运动的干扰、红外传感器由于红外光束的发散角度较大，检测精度不足，且容易受到列车的热红辐射影响。相比而言，激光传感器具有良好的精度和抗干扰能力，例如申请号201220345332.X所述红外LED光源测距的光电传感器，其通过采用多组红外LED测距单元和AD采样单元形成探测光幕，光幕位于屏蔽门和列车门的间隙处，起到安全保护作用。
然而，该技术中由于采用了多组红外激光测距单元，受限于红外激光器的本身体积大小，其激光光幕中各光线之间的间距会很大，因 此其产生控制信号的模式一般采用单点触发即控制的原则，即只要有其中1道或1道以上光幕检测到反馈信号，则传感器产生控制信号，这会经常性导致非必要触发的产生，例如，间隙中夹杂了纸张或塑料袋等物体，而当上述物体处于某激光线路上时，则传感器会产生报警信号，从而导致屏蔽门异常开启，反而会导致安全事故。
此外，现有该类型传感器的检测区域需要根据屏蔽门的门框大小进行预先设定。例如：传感器的目标用户是4米宽、2.5米高的屏蔽门，则需要预设设定好相应的4米宽、2.5米高的检测区域，同时非常严格的限制其固定安装位置，否则极易产生由门框或地面导致的误触发。
发明内容
