Description

Technical Field

[0001] This invention belongs to the field of energy-carrying communication, and specifically relates to a flexible optical receiving system for marine energy-carrying communication. Background Technology

[0002] Sunlight surrounds us every day. In 1880, Bell successfully conducted an experiment in optical telephony using sunlight as a light source, the atmosphere as a transmission medium, and selenium crystals as light receivers, achieving a communication distance of up to 213 meters. Today, cadmium telluride (CdTe) thin-film solar cells are used to collect energy by floating on water, in space, and in outer space.

[0003] For example, the existing patent CN2599483 provides an all-round concentrating solar energy collection device, but there is almost no information about energy-carrying optical communication. Summary of the Invention

[0004] In view of the defects or deficiencies of the prior art, the present invention provides a flexible optical receiving system for marine energy-carrying communication.

[0005] Therefore, the flexible optical receiving system for marine energy-carrying communication provided by the present invention includes a float assembly, a flexible solar energy receiving film, a distributed current energy concentrator, a signal transmitter, and a signal conditioning circuit. The float assembly is provided with an air and device accommodating cavity; The flexible solar energy receiving film is equipped with multiple photoelectric conversion circuits, and the multiple photoelectric conversion circuits are connected in parallel; The flexible solar energy receiving film is disposed on the top of the float assembly; the distributed current energy concentrator and signal conditioning circuit are disposed in the air and device housing cavity of the float assembly; the signal transmitter is disposed at the bottom of the float assembly. The input terminal of the signal conditioning circuit is connected to at least one photoelectric conversion circuit on the flexible solar energy receiving film, and the output terminal of the signal conditioning circuit is connected to the signal transmitter; the distributed current energy concentrator is connected to the remaining photoelectric conversion circuits on the flexible solar energy receiving film, and the distributed current energy concentrator is connected to the signal transmitter.

[0006] An optional embodiment includes a float assembly comprising a semi-enclosed bracket, an air pump, and a center-of-gravity stabilizing anchor air transmission pipe. The semi-enclosed bracket comprises a hollow spherical float, the inner cavity of which serves as an air and device containment cavity. The hollow spherical float has a support at its top and a through hole at its bottom. The center-of-gravity stabilizing anchor is installed at the through hole and connected to the support via a chain. The flexible solar energy receiving film is installed on the support. The distributed current energy concentrator, signal conditioning circuit, and air pump are installed inside the hollow spherical float. The air pump is connected to the outside via the air transmission pipe. The air pump is connected to the distributed current energy concentrator for power supply. The signal transmitter is installed on the center-of-gravity stabilizing anchor.

[0007] An alternative option is to include a barometric pressure detector installed inside the hollow spherical float, powered by a distributed current energy concentrator.

[0008] An alternative approach is to gradually reduce the inner diameter of the bottom of the hollow spherical float until it becomes a through hole.

[0009] An alternative is that the support is a flat plate, and the center of gravity stabilizing anchor is connected to the support at three points via a chain.

[0010] An alternative approach is that the signal conditioning circuit includes an optical transimpedance amplifier, a secondary amplifier, and an optocoupler isolator, wherein the optical transimpedance amplifier is used to convert the current signal into a voltage signal; the secondary amplifier is used to amplify the voltage signal a second time; and the optocoupler isolator is used to isolate the current transmitted to the distributed current energy concentrator.

[0011] Alternatively, the signal transmitter may be a blue-green light transmitter or an ultrasonic reflector.

[0012] An alternative is that the flexible solar energy receiving film is made of cadmium telluride.

[0013] The system of this invention utilizes a flexible solar energy receiving film to collect light energy and receive light signals. Simultaneously, it employs an air cavity within a float assembly to achieve an air self-stabilization system. In a preferred embodiment, an air pump and a pressure monitor are used to dynamically adjust the air pressure difference, ensuring the marine stabilization of the flexible receiving film. Furthermore, energy and communication signals are used to modulate blue-green light for energy-carrying communication with marine targets.

[0014] In addition, the system of this invention is a stable system with no energy consumption. Through an airbag device formed by gravity difference, it achieves stable adhesion to the ocean, forming a self-stabilizing system without power. It employs dynamic adjustment of air pressure to ensure stability and continuity. Furthermore, it utilizes a flexible solar energy receiving film to collect light energy and receive light signals, enabling the transmission of energy-carrying information between airborne and marine targets. Moreover, it can use energy and communication signals to modulate blue-green light for the transmission of energy-carrying information to deep-sea targets, thereby achieving cross-domain energy transmission from air to sea surface to deep sea. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of a flexible optical receiving system for marine energy-carrying communication provided by an embodiment of the present invention. Detailed Implementation

[0016] Unless otherwise specified, the scientific and technical terms used in this article are intended for understanding by those skilled in the art.

[0017] In a specific embodiment, the connection points of the various devices or structures of the present invention are connected by waterproof connectors.

[0018] To facilitate the explanation of specific embodiments of the present invention, the present invention will now be described in detail with reference to the accompanying drawings.

[0019] See Figure 1 As shown, the system of the present invention includes a float assembly, a flexible solar energy receiving film 1, a signal transmitter 4, a distributed current energy concentrator 6, and a signal conditioning circuit 9. The float assembly contains an air chamber and a device housing cavity to provide a dry space for each functional device and ensure the system floats stably on the water surface. Solar energy received by the flexible solar energy receiving film 1 is converted into a current signal by a multi-channel photoelectric conversion circuit. At least one current signal is converted into an electrical signal for optical communication after being processed by the signal conditioning circuit through parallel connection, impedance matching, and amplification. This optical communication electrical signal is emitted by the signal transmitter. The remaining current signals are transmitted to the distributed current energy concentrator 6, where they are stored and used to power the devices within the system.

[0020] When using the system of the present invention, the flexible receiving system of Tianhai Communication is first deployed on the sea surface to ensure that the solar energy film adheres to the sea surface, and then the float assembly is used to cover the sea surface to ensure that the solar energy film is not submerged by seawater.

[0021] Figure 1The system shown includes a float assembly comprising a semi-enclosed bracket 2, which includes a hollow spherical float. The hollow spherical float has an inner cavity that houses air and components. The top of the hollow spherical float is equipped with a support, and the bottom has a through hole. A center-of-gravity stabilizing anchor is installed at the through hole and is connected to the support via a chain. A flexible solar energy receiving film is installed on the support. A distributed current energy concentrator 6, a signal conditioning circuit 9, and an air pump 5 are installed inside the hollow spherical float. The air pump 5 is connected to the outside via an air transmission pipe 8. The air pump is connected to the distributed current energy concentrator for power supply. A signal transmitter 4 is installed on the center-of-gravity stabilizing anchor 7.

[0022] The flexible solar energy receiving film 1 receives and converts current energy and current signals, which are then connected to the interior of the semi-enclosed bracket 2 via a waterproof connector. The semi-circular semi-enclosed bracket 2 houses an air pump 5, a distributed current energy concentrator 6, and a signal conditioning circuit 9. Part of the current energy collected by the flexible solar energy receiving film 1 is stored by the distributed current energy concentrator 6, and part of the current signal is connected to the signal conditioning circuit 9. The signal conditioning circuit 9 consists of an optical transimpedance amplifier, a secondary amplifier, and an optical coupler isolator, achieving current paralleling and impedance matching, signal amplification, and ultimately, the conversion of the photoelectric communication signal. After processing by the signal conditioning circuit 9, the electrical signal for optical communication is obtained. The center-of-gravity stabilizing anchor 7 is connected to the top support of the semi-circular semi-enclosed bracket 2 via a chain.

[0023] In a specific embodiment, the flexible solar energy receiving film 1 is a flexible solar cell film composed of cadmium telluride material. The flexible solar energy receiving film 1 is attached to a semi-circular semi-enclosed bracket 2. The flexible solar energy receiving film 1 has a multi-parallel connection, divided into 256 groups. Each group has 16 parallel solar receiving cell lines, with an overall layout of 16 parallel lines * 256. Among these 16 lines, one is selected as a communication detection line, and the rest are used as energy harvesting cell materials. After the distributed current signal is converged, it is connected into the semi-circular semi-enclosed bracket 2 through current parallel connection and impedance matching design. The current is converted into a voltage signal by the signal conditioning circuit 9, and the remaining photoelectric converted current enters the distributed current energy convergent 6 to realize energy harvesting.

[0024] In the above embodiment, the semi-circular semi-enclosed bracket 2 is composed of an acrylic cover and polytetrafluoroethylene. The exterior is a semi-circular structure, with the bottom inner diameter gradually decreasing until a through hole is formed. A flat plate support matching the size of the flexible solar energy receiving film 1 is mounted on the semi-circular structure. The interior is a hollow structure used to fill the cavity and install the air pump 5, the distributed current energy convergent 6 (impedance matching 50 ohms to prevent high-speed signal reflection), and the signal conditioning circuit 9. The air transmission pipe 8 is fixed to the lower outlet of the hyperboloid inner wall. The center-of-gravity stabilizing anchor 7 is chained to the semi-circular semi-enclosed bracket 2, achieving a three-point connection. Below the center-of-gravity stabilizing anchor 7 is the underwater blue-green light emitter 4.

[0025] Air pump 5 is a waterproof pressure pump with both air intake and exhaust functions, and it also has a check valve. The gas is connected to the outside world through air transmission pipe 8, which is made of non-metallic materials. The power supply room relies on the electrical energy stored in the distributed current energy collector 6.

[0026] The underwater blue-green light transmitter 4 converts the voltage signal output by the signal conditioning circuit 9 into blue-green light suitable for seawater channels, and converts the power supply of the distributed current energy concentrator 6 into blue-green light energy for underwater transmission. The blue-green light uses a continuous light source and can be transmitted to specific deep-water targets.

[0027] Figure 1 The specific implementation steps for using the system shown are as follows: S01, Deploy the flexible optical receiving system for energy-carrying communication on the sea surface, ensuring that the flexible solar energy receiving film 1 is attached to the sea surface, the semi-enclosed bracket 2 is covered on the sea surface, and the center of gravity stabilizing anchor 7 is stably lowered into the sea. S02, the air pump 5, distributed current energy concentrator 6, and signal conditioning circuit 9 inside the semi-circular semi-enclosed bracket 2 start working after self-testing. The air pump can connect to the outside to add air, creating a pressure difference with the atmospheric pressure at the ocean surface. A pressure detector 3 is installed in the system to detect whether there is sufficient air pressure inside the semi-circular semi-enclosed bracket 2.

[0028] S03, when the air in the cavity is insufficient or increased due to the presence of undercurrents caused by ocean waves, the air pump 5 is used to release or fill the air cavity. The amount of pressure difference is related to the weight of the overall flexible optical receiving system. In addition, the lower stage of the semi-circular semi-enclosed bracket 2 adopts a double-curved surface structure with a narrow inner diameter and a sunken bottleneck, which makes the center of gravity and the air cavity outlet deviate from the sea surface, making it difficult for undercurrents to leak air or overturn the entire system.

[0029] S04: A flexible light receiving system is set up to receive light illuminating the sea surface. The collected current energy is stored in a distributed current energy aggregator 6. The current signal is connected to a signal conditioning circuit 9. The signal conditioning circuit 9 realizes the parallel connection and impedance matching of the current. The signal circuit amplification circuit consists of an optical transimpedance amplifier, a secondary amplifier and an optical coupler isolator to realize the conversion of photoelectric communication signals. The energy stored in the distributed current energy aggregator 6 and the signal output from the conditioning circuit 9 are introduced to the bottom of the center-of-gravity stabilizing anchor 7 through wires. The information and energy are then transmitted to the target in the deep ocean using an underwater blue-green light transmitter 4.

[0030] When the system is working, it receives optical signals from the sea surface and transmits signals from other carriers in space, such as ships, aircraft or satellites, which are optical transmission and communication payloads.

[0031] The embodiments described above are merely preferred embodiments of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solutions of the present invention should be included within the protection scope of the present invention.
