摘要:
海洋测绘包括各类专题海图以及影像数据,对海上信息化布局具有重要意义。在海洋测绘领域需要通过多个渠道来获取数据,但这一过程中会受多种因素影响,导致数据采集不稳定和处理不及时等问题,在一定程度上制约了测绘数据的应用,为此,研究海洋测绘数据采集与处理系统。在硬件方面,融合GIS系统、自动化技术以及云技术,在多层分布式的结构中设计系统功能框架,以AD7655芯片作为同步采集与处理电路的核心,在多通道并行的基础上建立采样通路,获取与处理海洋测绘数据关键信号。在软件方面,以自动化编程控制技术建立采集逻辑,对应不同的数据类型采集海洋测绘数据;选择动静结合模式构建处理流程,分别通过差分方程和校正方程处理数据,实现系统设计。实验测试对比表明:以相对时域特征和绝对时域特征为标准,新系统采集到的海洋测绘数据信号能够与原始信号保持一致,且可以同时满足实时性与稳定性的需求,具有应用价值。
Abstract:
Marine surveying and mapping, including all kinds of thematic charts and image data, is of great significance to the layout of Marine information. In the field of Marine surveying and mapping, it is necessary to obtain data through multiple channels, but this process will be affected by a variety of factors, resulting in unstable data collection and processing in a timely manner, which restricts the application of surveying and mapping data to a certain extent. Therefore, the data acquisition and processing system of ocean surveying and mapping is studied. In terms of hardware, GIS system, automation technology and cloud technology are integrated to design the functional framework of the system in a multi-layer distributed structure. The AD7655 chip is used as the core of synchronous acquisition and processing circuit, and the sampling path is established on the basis of multi-channel parallel to obtain and process key signals of Marine mapping data. In the aspect of software, the acquisition logic is established by the automatic programming control technology to collect the ocean surveying and mapping data corresponding to different data types. The system design is realized by using difference equation and correction equation to process data. The experimental results show that the Marine surveying and mapping data signal collected by the new system can be consistent with the original signal based on the relative time domain characteristics and absolute time domain characteristics, and can meet the requirements of real-time and stability at the same time, which has application value.
