摘要
介绍了一种新型数字式电子水准仪的实现方法,其充分利用载码的周期特征实现CCD信号的快速解码,利用载码的相位信息获取精测值,利用调制在载码中的测量码获取粗测值,本文方法具有测量快捷、成本低廉、分辨力高并可实现人工读数等优点。
A new decode method for digital electronic level is presented. It gets the high speed to demodulate CCD signal by using periodic feature of carrier code fully, gets fine measured values using carrier phase information, gets coarse measured values using the measured code demodulated from carrier code. It has the advantages such as fast, cheap, accurate, and can realize artificial reading.
