摘要:: 基于蓝绿激光的海洋激光雷达探测技术具有较高的探测效率和探测点密度,在浅海水域具有独特应用优势。应用需求的复杂化和多样化使得海洋激光雷达系统需要集成多种不同类型的设备, 因此通过软件控制保证多种设备间的协同合作显得尤为重要, 软件系统逐渐成为海洋激光雷达系统的核心技术。该文以海洋激光雷达系统为研究对象, 针对项目需求和系统的硬件组成, 设计了一套海洋激光雷达系统控制软件, 控制软件设计分成四个部分——通信协议设计、功能模块设计、多线程设计和界面设计。最终采用 UDP(user datagram protocol)网络通信协议的控制软件系统实现了对海洋激光雷达各设备的控制,并完成了采样参数的设定、处理、波形显示以及水体回波信号滤除等任务。

Abstract:: In shallow coastal waters,the oceanic lidar detection technology based on blue-green laser has unique application advantages because of the high detection efficiency and detection point density. The complexity and diversity of application requirements make the oceanic lidar system need to integrate a variety of different types of equipment. Therefore, it is particularly important to ensure the cooperation among various equipment through software control. The software system has gradually become the core technology of oceanic lidar system. A set of oceanic lidar system control software is designed based on the project requirements and system hardware components,which includes communication protocol design, function module design, multiple thread design and interface design. Finally,the UDP (user datagram protocol) network communication protocol is used to realize the control of various equipment of the oceanic lidar in the control software system. Moreover,the tasks of setting sampling parameters,processing,waveform display and water echo signal filtering are also completed.
