一、概述编码器是经纬仪的精密测量元件。以独立状态工作的编码器,其自身可以做到较高的精度,一般可达到σ=1～2″;但实际的工作状态,是将编码器各不相同的部件与总机机体及转动的轴相联接,由经纬仪的横轴或竖轴传动,带动码盘,从而测出转角。编码器与总机的联接型式有刚性和柔性之分,所谓刚性联接(即为散装),是将码盘等运动及不动的部件,分别 First, an overview Encoder is a theodolite precision measurement components. Encoders that work in an independent state can achieve high accuracy by themselves, generally achieving σ = 1 ~ 2 ". However, the actual working state is that the encoder with different components and the switchboard body and the axis of rotation Connected by the theodolite horizontal axis or vertical axis drive, drive code wheel to detect the corner.The encoder and the switchboard has a rigid and flexible type of connection, the so-called rigid connection (that is, bulk), the code plate, etc. Sports and immobility components, respectively
