Description

一种基于红外激光测量装载率的装置 技术领域
本发明涉及装载率检测技术领域，具体为一种基于红外激光测量装载率的装置。
背景技术
目前在市场上还没有成熟的装载率检测的设备，不成熟的方案采用超声波的方式来进行测量，也未进行商品化。超声波测量存在以下缺陷：高精度(大于5％)成本居高，单体达到100元以上；盲区较大，大于20cm；电路设计较为复杂，需要模拟电路，并且需要复杂的校准；此外，布线较为复杂，采用多股线缆，导致检测效率低。
红外测距传感是用红外线为介质的测量系统，按照功能可分成五类：(1)辐射计，用于辐射和光谱测量；(2)搜索和跟踪系统，用于搜索和跟踪红外目标，确定其空间位置并对它的运动进行跟踪；(3)热成像系统，可产生整个目标红外辐射的分布图像；(4)红外测距和通信系统；(5)混合系统，是指以上各类系统中的两个或者多个的组合。按探测机理可分成为光子探测器和热探测器。红外传感技术已经在现代科技、国防和工农业等领域获得了广泛的应用。利用的红外测距传感器LDM301发射出一束红外光，在照射到物体后形成一个反射的过程，反射到传感器后接收信号，然后利用CCD图像处理接收发射与接收的时间差的数据。经信号处理器处理后计算出物体的距离。这不仅可以使用于自然表面，也可用于加反射板。测量距离远，很高的频率响应，适合于恶劣的工业环境中。
目前，还未将红外激光传感器应用到检测装载率的设备中。

与现有技术相比，本发明的有益效果是：本发明测量精度较高，采用新型红外激光测距传感器进行测量单位面积的高度，通过计算实现车厢容积率的检测，能做到2％以下，采用红外激光传感器测量，成本较低；此外，单体传感器采用级联的方式，安装简单稳定可靠，另外，采用倾斜安装的红外激光传感器盲区小，更适合箱体测量。
