发布时间:2019-02-09 12:14
【摘要】:助航设施通常布设在江河、沿岸及海湾的通航水域,用以标识航道的走向、界限及水上和水下的碍航物,是保障水上交通安全的重要基础设施,其工作状态是否正常直接影响海运事业的发展。 论文依托福建省科技厅高校产学合作科技重大项目“面向行业应用的遥测监控关键技术研究及其产业化”(项目编号:2011H6009)而展开的,应用移动互联、数据加解密及故障诊断等技术,在Android平台上研制了一套助航设施现场测控系统,可完成对助航设施的现场动态检测和状态控制,有利于及时发现故障及其原因,从而缩短故障设施的维护时间,提高效率,进而提高助航设施的正常工作率,最终提升保障水上交通安全的能力。 论文根据助航设施现场作业的特点,提出了详细的系统设计方案;将低功耗、低成本、数据传输稳定的蓝牙无线交互技术用于测控系统与助航设施的交互,并运用AES和RSA混合的加解密算法对交互的数据加密和解密;结合基于标识符的规约数据帧解析方法及CBR和PBR级联的方式进行故障诊断,快速地发现并排除故障;通过Socket与远程监控中心进行无线交互,并结合卫星电子地图实现资源共享;依据Android系统的用户界面设计原则,设计了具有良好用户体验的界面。此外,论文还初步实现了轨迹追踪、自我定位、位置搜索及拍照标识等功能。最后,对本课题的研究内容进行了归纳总结,提出进一步的研究建议。
[Abstract]:Navigational aids are usually located in navigable waters of rivers, coasts and bays to mark the course, boundaries and obstructions on and under water. They are important infrastructure for the safety of water traffic. Whether its working condition is normal affects the development of shipping business directly. This paper is based on the "key Technology Research and industrialization of Telemetry and Monitoring oriented to the Application of Industry" (Project number: 2011H6009), which is a major project of science and technology cooperation in colleges and universities of Fujian Provincial Science and Technology Department. Based on the techniques of data encryption and decryption and fault diagnosis, a set of on-site measurement and control system for navigation aids is developed on the platform of Android. The system can realize the field dynamic detection and state control of navigation aids, and is conducive to the timely discovery of faults and their causes. In order to shorten the maintenance time of fault facilities, improve the efficiency, and then improve the normal working rate of navigation facilities, and ultimately enhance the ability to ensure the safety of water traffic. According to the characteristics of the site operation of the navigation aid facility, the detailed system design scheme is put forward in this paper. The Bluetooth wireless interaction technology with low power consumption, low cost and stable data transmission is used in the interaction between measurement and control system and navigation aids, and the encryption and decryption of the interactive data is made by using the mixed encryption and decryption algorithm of AES and RSA. Combined with the protocol data frame analysis method based on identifier and the concatenation of CBR and PBR, the fault diagnosis can be carried out quickly, and the remote monitoring center can be wirelessly interacted by Socket, and the resources can be shared with satellite electronic map. According to the principle of user interface design of Android system, the interface with good user experience is designed. In addition, the functions of track tracking, self-location, location search and photo identification are also implemented. Finally, the research content of this topic is summarized, and further research suggestions are put forward.
