摘要: 为解决海上复杂观测环境下长距离精密跨海高程传递准确照准观测目标的难题,在采用全站仪三角高程测量方法进行长距离跨海高程传递中,设计了一种便携式远距离照准觇标,该设备结构简单、尺寸小、质量小,可根据观测路线长度和大气环境调整光线宽度与亮度,满足不同路线长度下的夜晚观测要求,解决了长距离照准目标模糊和观测数据离散问题,并辅以数据采集软件进行观测数据的自动验算,大幅度提升了测量工作效率。经深中通道工程5.5 km跨距的跨海高程传递测量实践验证,该方法满足长距离高精度跨海高程传递测量的需要,测量结果可达二等跨水准测量的精度要求。

Abstract:

To accurately transfer the leveling data at a long distance under complex sea environment and conditions, a portable long-distance illuminating beacon lamp is designed using the total station trigonometric leveling method for long-distance cross-sea elevation transfer. The light width and brightness of the beacon can be adjusted as per the length of observation route and atmospheric environment to meet the night observation requirements under different route lengths; it is simple in structure, small in size, and light in weight. Moreover, the dispersion of target and observation data in long-distance illumination is avoided. With the help of data acquisition software, the automatic verification of observation data is realized, and the surveying efficiency is considerably improved. The beacon with a measuring distance of 5.5 km was applied for the ShenzhenZhongshan link, and the applicable results meet the accuracy requirement of second-class cross-sea level survey, which indicates the feasibility of the beacon in precise long-distance cross-sea elevation transfer.
