摘　　要：针对现阶段世界时实时性要求越来越高的问题,结合天顶筒的观测特点,初步设计并建立了以丽江、德令哈、洛南为3个观测站点,和以临潼为数据处理中心的数字天顶筒远程观测系统。与传统的光学UT1测量系统相比,该观测系统具有无人值守、远程控制、自动观测、在线处理和数据实时传输的特点,能够满足我国世界时的测量需求。In order to satisfy the increasing needs of the Universal Time of self-measurement, a digital zenith telescope Universal Time observation system, with Lijiang, Delingha and Luonan stations and Lintong data processing center, was designed and established. Compared with the traditional optical UT1 measurement system, the digital system has the characteristics of unattended, remote control, automatic observation, online processing and real-time data transmission, which can meet China’s measurement requirements of the Universal Time.
