摘　　要：大视场双筒巡天望远镜(R2Pub)采用双镜筒双终端设备同时巡天,极大提高实测天文观测效率。常规实测天文控制系统不能主观控制协调多终端系统。采用分布式控制与通讯方法,可高效协调观测终端,实现列表观测和自定义观测计划。连续观测的实验表明,不同终端同时观测时,24小时内本底中值和均值浮动均在1σ范围内,观测稳定可靠。The large-ficld binocular survey telescope(R2Pub)uses dual tubes and dual terminal cquipment to simultaneously survey the sky,which greatly improves the cfficicncy of actual astronomical observations.Conventional actual astronomical control systems cannot subjectively control and coordinate multi-terminal systems.Using distributed control and communication methods,it can Efficiently coordinate observation terminals to achieve list observations and customized observation plans.Continuous observation experiments show that when different terminals observe simultaneously,the background median and mean fluctuations within 24 hours are within the lo range,and the observations are stable and reliable.
