Description

间接式分体型被动激光角位传感器
技术领域:
本发明涉及传感装置，特别涉及一种交通工具的角位传感器。
背景技术：
角位的检测可以用很多的方式来完成，如电位器、霍尔元件、可变电容器、旋转编码器等等都可以作为检测角位的传感器，这些器件有一个共同的使用形式：它们是由一个联动机构带动，使这些器件与检测对象同步转动，在转动的时候，传感器产生磁、电、脉冲等的数值变化。问题是：1，联动机构难免产生精度的误差，精确度差。如检测船舵角位是一个根据平行四边形对边平行的原理构成联动机构，实际精度很难达到0.1度。2，这些器件不是专门为角位传感设计的，数值变化的线性不完美，影响精确度。3，零位调整困难，有一类的检测如轮船的舵角、汽车的方向，基本不大于180度，但是需要确定零位，现有的用于角位检测的传感器件，除了旋转编码器都不能360度的检测，给零位的确定增加不少的麻烦。4，这些器件产生的都不是直接可以使用的数码信息，是需要转换的模拟或脉冲信号，影响整体的响应时间。
发明内容：
本发明的目的 是发明一种间接随同被检测物体一起转动的、直接读取角位变化信息的 间接式分体型被动激光角位传感器。
本发明是这样实现的：间接式分体型被动激光角位传感器由间接件和主体构成，主体由激光识别器、标识件、电路板、连接件和外壳组成，激光识别器、标识件、电路板、连接件密封在外壳内，标识件上排列着标识，标识是激光识别器可以识别的记号，一个记号表示一个数值，激光识别器能够读取标识件上的标识，电路板能够将激光识别器读取的标识通过编解码和计算成为可以直接使用的格式化数码信息，间接件由主动件和被动件构成，主动件与被动件上有齿条。
其特征是：标识件固定在连接件上，连接件固定在被动件上，主动件固定在被检测物体上，激光识别器是固定的，激光识别器的读取口对着标识件上的标识。
其中，标识件上标识的长度大于读取口在标识件上经过的路径的长度。
其中，标识包含角位信息和校验信息。
其中，标识有平面标识和立体标识。
本发明的精度相当地高，可以适用于各种角位检测场合使用。

激光识别器10的读取口11对着标识件20上的标识21，标识件20是连接在连接件34上，连接件34连接在间接件30的被动件32上，所以标识件20是与被动件32同步行动的，被动件32与主动件31之间有齿条33啮合直接同步转动，主动件31连接在被检测物体60上，当被检测物体60转动的时候，被动件32一样转动，标识件20与被检测物体60也一样转动。
标识件20上排列的标识21，是激光识别器10可以识别的记号，标识21有平面标识22和立体标识23，一个记号表示一个数值，标识21在标识件20上的排列，是与被检测物体60转动的方向是一致的，标识21包含角位信息和校验信息，标识件20上标识21的长度大于读取口11在标识件20上经过的路径的长度，激光识别器10通过读取口11读取标识件20上的标识21，将读取的信息通过连接线12传递给电路板40，电路板40由电子元件41构成，能够将激光识别器10从标识21读取的信息，通过编解码和计算成为可以直接使用的格式化数码信息，接口51是接入电源和接出信息的部件。
图2是垂直式实践例的 侧视剖面示意图。
