摘要
为改变传统的管线外业调查流程,将探查和测量合为一步,实现数据采集的数字化,降低地下管线外业调查的复杂度,提出将PDA用于地下管线外业记录的研究思路。首先根据系统需求分析,设计系统逻辑结构图和地下管网数据结构表,然后在功能设计的基础上使用EPSCE软件的二次开发工具开发了系统功能,最后进行验证,取得较好的运行效果。为地下管线外业调查工作进行有益的探索。
In order to change the process of field investigation in undergroud pipelines, combining the field ascertainment and surveying process, digitizing the data collection and reducing the complexity of pipelines, this paper brings forward research of field investigation in undergroud pipelines based on PDA. According to the systems＇s needness analysed, the systems logic structure and pipelines data structure are designed. Then system functions are realized by the secondary development tool EPSCE Application Builder based on functions design. At last, it is validated using Area pipelines datas and runs well. This paper is useful for field investigation in undergroud pipelines.
