摘　　要：针对磁通门经纬仪人工读取时间存在误差问题,研发智能化较高的DI仪辅助数字观测系统,提供准确的观测时间;采用高精度数字温、湿度传感器代替模拟温湿度计记录观测环境参数,读数更方便、更准确。A higher intelligent assist digit observing system for DI transit is invented to overcome the lower temporal accuracy in artificial reading of fluxgate theodolite. It provided accurate observation times for observers. And numerical reading became more convenient and more accurate through recording and observing environment parameter utilized analogue thermograph and hygrometer replace by high-accuracy digital temperature humidity sensor.
