Diver safety early warning system and control method thereof

Abstract

The invention discloses a diver safety early warning system and a control method thereof, and relates to the technical field of diving safety early warning. The safety early warning system comprises a wearable early warning host and a wireless pressure sensor, the early warning host is worn on the ear position of a diver, and the wireless pressure sensor is installed on a primary valve of the gas cylinder regulator. The corresponding voice and warning sound are broadcasted through the loudspeaker so that the diver directly receives related information, the warning lamp is synchronously used for assistance, and safety-related early warning is effectively carried out on the diver; an underwater acoustic transducer is used for transmitting and receiving information, mutual communication between gas cylinder pressure monitoring and an early warning host is achieved, and early warning on the safety of the residual gas amount is achieved; pairing and communication among the early warning hosts are realized through the underwater acoustic transducers, distance measurement and information intercommunication among the submerged partners are realized, and early warning of safety of the submerged partners is realized; and early warning of the diving depth, the floating speed and the diving speed is realized through the hydraulic sensor.

Description

technical field [0001] The invention relates to the technical field of diving safety early warning, in particular to a diver safety early warning system and a control method thereof. Background technique [0002] When diving, divers maintain their lives and adjust their own buoyancy through the air in the gas cylinder. Divers are required to move within a certain depth. Exceeding the predetermined depth will bring life danger. At the same time, diving or surfacing too fast will bring health damage to divers. To avoid risks, a safety stop for a certain period of time is necessary. For the sake of safety, at least two people are required to go together when diving. Due to environmental factors such as currents and visibility, or physical and psychological factors, it is easy for the diving partner to get lost. At present, divers wear diving watches during diving activities. The diving watches can display information such as the depth of the diver's location, diving speed, saf...

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate reading data, the diving watch is worn on the wrist or arm. The flashing warning is easy to be ignored due to the small size of the screen or diver’s attention.

It is inefficient to check the remaining gas volume in the gas cylinder through the pressure gauge and inquire through gestures

At present, there is no effective early warning of the loss of the diving buddy. If the diving buddy is found to be lost, it can only be dealt with according to the routine procedures, which greatly affects the diving experience and is very dangerous.
