Product Upgrade - Thunder Shield Fishing Protection System - Sea Guardian LDS-002a

The Thunder Shield Fishing Protection System - Sea Guardian (hereinafter referred to as Thunder Shield Fishing Protection) is an intelligent terminal software developed by our company for smart aquaculture (marine ranching) applications. It pioneers a business function centered on event management, including: target detection, linkage tracking, snapshot evidence collection, intelligent early warning, event tracing, and more. It can connect to high-resolution security radars and mainstream advanced PTZ optical devices, with easy connection operations. The specific connected devices can be seen in the following figure 1-1 system architecture diagram. By fusing and analyzing detection information from high-resolution radars and other intelligent sensors, it can achieve the industry's lowest false alarm rate and the best level of intelligent classification alarms under all weather conditions.

Since the launch of the 2023 LDS-001 Thunder Shield Fishing Protection System - Sea Guardian, it has received significant attention. Based on feedback from various field applications, the Thunder Reach team continuously updates and enhances product performance, and will launch the Thunder Shield Fishing Protection System - Sea Guardian LDS-002a version in December 2024. This version supports more convenient troubleshooting for front-end and back-end separation. The specific differences between the two versions can be seen in the following figure 1-2 Thunder Shield Fishing Protection System Version Comparison Diagram.

3. Supporting Hardware Device Function List
3.1 Detection Devices
By connecting detection devices, we can quickly identify the target's location and achieve real-time monitoring of important information such as the position, speed, heading, and trajectory of vessels on the software platform. This not only effectively prevents poaching and illegal fishing incidents but also allows for quick location of distressed vessels in case of maritime accidents or other emergencies, coordinating rescue resources and improving rescue efficiency.
3.1.1 Radar

Radar equipment is a fundamental component of the Thunder Shield Fishing Protection System. It is usually deployed on high towers in marine areas, and by deploying high-precision radar, it can achieve all-round, all-weather monitoring of low-altitude and ultra-low-altitude areas.

The role of radar in the Thunder Shield Fishing Protection System: Radar emits electromagnetic waves to obtain all target location information reflected back and provides the data to the system software platform. Once the platform obtains the target information, it can display the target's trajectory, position, speed, height, and other basic information in real-time, and can also distinguish target types to provide important basis for subsequent linkage and handling.

3.1.2 AIS Ship Identification System

The AIS ship identification system is an important maritime safety and traffic management tool, mainly divided into AIS transmitters and AIS receivers. AIS transmitters are usually installed on registered vessels by maritime management agencies, sending real-time vessel position, heading, speed, and vessel information such as name and call sign via GPS to VHF channels; AIS receivers can obtain all vessel information by receiving VHF channels.
The role of the AIS ship identification system in the Thunder Shield Fishing Protection System: The AIS receiver sends all received vessel information to the Thunder Shield Fishing Protection System via the network. After the platform obtains the vessel information, it analyzes the dynamic important information such as vessel position, speed, and heading through backend algorithms for conversion and storage, and displays the stored vessel information in real-time on the platform map interface, allowing for a more intuitive and accurate view of all vessels equipped with AIS transmitters in the marine area. The Thunder Shield Fishing Protection System then combines all vessel information detected by radar for algorithm comparison, displaying all vessels with and without AIS installed on the platform map interface, enabling quick differentiation between legal and illegal vessels in the marine area. This is very helpful for marine aquaculture management and search and rescue operations.

3.1.3 Electronic Identification Badge (Friend or Foe Identifier)

The electronic identification badge (friend or foe identifier) is mounted on internal operation vessels to identify the friend or foe attributes of targets detected by radar, usually installed in conjunction with radar.

The role of the electronic identification badge (friend or foe identifier) in the Thunder Shield Fishing Protection System: The friend or foe identifier transmits data to the system software platform via wireless network. After the platform receives the data from the friend or foe identifier, it calculates and compares the radar data based on internal algorithms, identifies black and white lists, and finally displays it in real-time on the control interface, allowing for an intuitive view of whether it is a friendly vessel, quickly and accurately identifying vessel identity, ensuring that only authorized vessels can enter specific areas.

3.2 Linkage Devices
3.2.1 Optical and Electronic Devices

Optical and electronic devices are an important part of the Thunder Shield Fishing Protection System. The optical and electronic locking and tracking technology complements and enhances detection devices such as radar. Optical and electronic devices can work day and night, stably tracking targets under complex environmental conditions, and can capture high-definition images and infrared thermal imaging of targets using high-resolution cameras and infrared thermal imagers.

The role of optical and electronic devices in the Thunder Shield Fishing Protection System: The system software platform connects to optical and electronic devices, and based on the target location and distance information provided by detection devices, the backend algorithm links the optical and electronic devices to track and lock onto the target in real-time. During the tracking process, it collects target images and videos, supporting subsequent playback and evidence collection, providing important clues to combat theft.
