【摘要】：渔业执法是维护渔区正常渔业生产秩序,保障合法生产渔民的利益,维护渔业资源可持续发展的重要手段。执法取证工作是判断渔船是否违规作业的重要依据,然而,海上执法取证存在距离远,海面环境影响大,稳定度和精度要求高等特点,普通的相机和录像机很难同时满足海上取证的需要,因此,有必要加强对渔政船执法取证系统的研究,改进渔业执法取证的方式。本文针对渔政普通取证系统存在的执法难、取证难等问题,提出一种基于目标定位的渔政船执法取证系统的解决方案。针对渔政执法过程实际需求,提出系统的主要技术指标,设计了系统的总体方案;通过对传统的导航定位技术分析,研究了执法取证系统的定位技术,推算出目标定位公式;通过对定位模块的功能和原理结构的分析,提出了基于TMS320F2812处理器的定位模块,设计了定位模块的软硬件;实现了拍摄的过程中对目标船经纬度准确显示的功能,解决传统渔业执法视频证据中“地点”不足的难题,提高渔业执法效率,降低渔业执法成本,提升渔业执法人员执法的积极性。通过合作研发,渔政船执法取证系统已经调试使用,该系统在中国渔政311船安装使用,在南中国海的多次执行任务中获取大量的图片和录像资料证据,为后期处理国内、外渔业案件提供有力证据。随着我国在处理国内、国际海事纠纷事务法律的进一步规范化,对获取证据手段的要求在不断提高,渔政船执法取证系统在打击走私犯罪、处理国内外渔业纠纷、海上救捞、海上交通监管等发挥重要的作用。
[Abstract]:Fishery law enforcement is an important means to maintain the normal order of fishery production, protect the interests of legally produced fishermen and maintain the sustainable development of fishery resources. Law enforcement and evidence collection is an important basis for judging whether fishing vessels are engaged in illegal operations. However, maritime law enforcement and evidence collection is characterized by long distance, large sea level environmental impact, high stability and precision requirements, etc. It is difficult for ordinary cameras and video recorders to meet the needs of maritime forensics at the same time. Therefore, it is necessary to strengthen the research on the system of law enforcement and forensics of fishery administration vessels and improve the way of obtaining evidence from fishery law enforcement. In order to solve the problems of difficult law enforcement and difficulty in obtaining evidence in the common system of fishing administration, this paper puts forward a solution based on target orientation for the system of law enforcement and evidence collection of fishery administration ship. According to the actual demand of fishery administration and law enforcement process, this paper puts forward the main technical index of the system, designs the overall scheme of the system, studies the positioning technology of the law enforcement and evidence collection system through the analysis of the traditional navigation and positioning technology, and calculates the target orientation formula. Through the analysis of the function and principle structure of the positioning module, the positioning module based on TMS320F2812 processor is put forward, and the hardware and software of the positioning module are designed. It realizes the function of accurately displaying the longitude and latitude of the target ship in the process of shooting, solves the problem of "insufficient location" in the video evidence of traditional fishery law enforcement, improves the efficiency of fishery law enforcement, and reduces the cost of fishery law enforcement. We will enhance the enthusiasm of fishery law enforcement personnel in enforcing the law. Through joint research and development, the law enforcement and forensics system of the fishing administration ship has been debugged and used. The system has been installed and used on the Chinese fishery jing311 vessel, and has obtained a large amount of photo and video data evidence during several missions in the South China Sea, so as to deal with the domestic situation at a later stage. External fishing cases provide strong evidence. With the further standardization of domestic and international maritime dispute affairs in our country, the requirement of obtaining evidence means is constantly raised. The law enforcement and forensics system of fishery administration ship is cracking down on smuggling crime, dealing with domestic and foreign fishery disputes, and salvage at sea. Maritime traffic supervision plays an important role.
