大比例尺数字地图勘测系统小型化设计

Miniaturization Design of Large-scale Digital Map Surveying System

为了实现大比例尺数字地图勘测系统的小型化,研制了手持式数据采集处理终端,用于代替便携式计算机对全站仪进行控制,叙述了手持式数据采集处理终端的硬件设计和软件设计,描写了该终端的功能、性能及其应用情况。试验表明:手持式数据采集处理终端具有体积小、重量轻、连续工作时间长、携带方便、操作简单等特点,非常适合野外作业时使用。

In order to achieve the miniaturization of large-scale digital map surveying system, hand-held data collection terminal is developed to replace the portable computer to control the Electronic Total Station. The hardware and software designs of the hand-held data collection terminal are described. The terminal＇s functions, capability and applications are depicted. It is proved by the test that the hand-held data collection terminal has many features such as small size, light weight, long working time, portable, and easy to operate. It is very useful for field work.
