Design of Maritime Unmanned Detection System Based on Multi-mode Communication

In maritime environment detection, the buoy-based detection system is widely used because of its simplicity and economy. And it can work all-weather, long-term and continuously in the harsh maritime environment, which becomes one of the most important means of maritime detection. A maritime detection buoy system is designed to achieve real-time detection and high-speed data transmission while ensuring low power consumption and reliability of the system and increasing the detection range. A multi-mode communication system scheme using distance and bit error rate as priority indicators to select communication modes for data transmission is proposed. The x86 industrial personal computer(IPC) and STM32 single-chip microcomputer are used as the control core, and the multifunctional information fusion measurement and control system is used as the upper computer software, and a study on the key process design of the unmanned detection system is carried out. The experimental results show that the system has a flexible communication method, reduces power consumption while ensuring the reliability of the communication effect, and the transmission distance meets the expected design requirements, which has a certain reference value for the design of other buoy communication systems in the future.
