This invention discloses a ship dual-mode communication method and terminal based on adaptive region awareness. Multiple data points are input into a preset clustering model for cluster matching. If an existing cluster is matched in the preset model, the center and boundary information of the existing cluster are updated. Location point information is acquired and matched with all boundary information. If a match is successful, a region type signal is generated based on the matched boundary information; if a match fails, an unknown region signal is output. For region type signals, the target ship is controlled to use mobile communication and / or satellite communication; for unknown region signals, the target ship is controlled to use mobile communication for region signal analysis. This invention constructs a region signal model based on historical experience, enabling forward-looking decision-making, reducing the average energy consumption of the dual-mode communication terminal overall, improving the endurance of the ship terminal in open seas or areas with weak coverage, and ensuring communication reliability.

This invention provides an IoT-based intelligent lighting control system for high-mast lights, comprising a main station server, a computer terminal, a mobile terminal, a 4G / 5G base station, a communication conversion base station, and N dual-mode high-mast light lines. The N dual-mode high-mast light lines are interconnected, wirelessly connected to the communication conversion base station, wirelessly connected to the 4G / 5G base station, wirelessly connected to the main station server, and the main station server is connected to the computer terminal and mobile terminal via network communication; where N is a positive integer greater than 3. This invention utilizes HRF (Hyper-Radio Frequency) for flexible wireless data interaction and HPLC (Power Line Carrier) technology to ensure stable wired communication. The two complement each other to ensure communication reliability, adapting to different environments and scenarios and improving the overall communication performance of the system. The communication topology offers good flexibility, gradually achieving full coverage of lighting monitoring in application scenarios from points, lines, and surfaces.

The application discloses a method for constructing a MAC protocol of a UAV network, a transmission process of data packets with different priorities is modeled by a finite state Markov chain, and a cross-level priority promotion mechanism based on failure counting is introduced. The method aims to solve the problem of long-term blocking of low-priority services caused by traditional fixed-priority protocols in post-disaster emergency communication scenarios, thereby improving the overall throughput, reducing the average delay, and enhancing the fairness among multiple types of services while ensuring the strict service quality of high-priority services.
