Energy replenishment system for underwater IOT (Internet of Things) node based on supersonic wave

Abstract

The invention discloses an energy replenishment system for an underwater IOT (Internet of Things) node based on a supersonic wave, and the system comprises a supersonic energy transmitting module andan underwater IOT node receiving module. The supersonic energy transmitting module comprises a first controller, a first supersonic transducer, a drive circuit, a matching circuit, an intelligent holder, and a display circuit. The underwater IOT node receiving module comprises a second supersonic transducer, a rectification filter circuit, a voltage-stabilizing circuit, a charging circuit, and a second controller. The system takes the supersonic wave as an energy transmission carrier, can complete the energy replenishment for the underwater IOT node without any physical connection, guaranteesthe long-time stable operation of underwater power equipment, and is suitable for the safety power supply of equipment in flammable and combustible occasions and occasions which are liable to be affected by electromagnetic waves.

Description

Technical field [0001] The present invention relates to the technical field of ultrasound, in particular to an energy supply system for underwater IoT nodes based on ultrasound. Background technique [0002] Facing the particularity and complexity of the underwater environment, underwater Internet of Things technology provides new means for people to explore and develop marine resources. The perception, monitoring and rapid response of the underwater environment, as well as the interconnection between water and land objects, will inevitably require a large amount of underwater equipment. However, the life of the underwater Internet of Things is closely related to the life of the node, and a large number of battery-powered underwater equipment is usually difficult to obtain energy supplement. Using the traditional "salvage-replace-drop" underwater endurance mode will bring about problems such as poor water tightness and safety of the battery compartment. Therefore, in order to i...

Problems solved by technology

However, these studies are limited to ultrasonic-based energy transmission technologies in space environments. In free space, ultrasonic propagation attenuation is serious, and the transmission distance is relatively short. Compared with electromagnetic waves, there is no obvious advantage.

[0004] Existing wireless energy transmission technologies generally have problems such as short transmission distance, low efficiency, and easy electromagnetic interference in underwater environments. Traditional energy supply methods are prone to problems such as maintenance difficulties, poor flexibility and safety, and waste battery pollution.
