Abstract

A safety monitoring and management device for divers' underwater operations, involving underwater acoustic communication technology, the device includes two parts: an above-water monitoring and management platform and an underwater information sending and receiving node. The released voice information is stored in advance through the training stage, and the voice information commands are normalized and processed into effective standard information, which is transmitted using TFSK time-frequency modulation technology in underwater acoustic communication. While ensuring the reliable transmission and robustness of information, through Play back the pre-stored voice to ensure that divers can receive information conveniently, intuitively and reliably, and achieve the purpose of safety monitoring and management of underwater divers. The device uses the STM32 high-performance digital signal controller based on Cortex M4 as the core processor. The system has the characteristics of simple and convenient implementation, low power consumption, and high cost performance. This device can be used in diving entertainment, underwater rescue, marine ranching and other application scenarios.

Description

technical field [0001] The invention relates to underwater acoustic communication technology, in particular to a safety monitoring and management device for divers' underwater operations. Background technique [0002] In recent years, the diving industry has shown a steady growth trend around the world. The underwater environment is complex and often accompanied by great dangers. However, divers generally use hand gestures for underwater communication in underwater operations, and use signal ropes to communicate with the surface of the water. Communication, such methods will be largely affected by the underwater environment, and will affect the flexibility and range of activities of divers, which will lead to increased safety risks for divers, and it will be difficult to carry out effective signal transmission when encountering danger, which will easily lead to safety ACCIDENT. [0003] At present, the most effective means of wireless communication between water and underwa...
