Submarine optical positioning beacon system with self-generating capability

Abstract

A submarine optical positioning beacon system with self-generating capability, which has an array of underwater beacons. When the underwater rover moves to the vicinity of an certain underwater beacon, the underwater beacon's COMS sensor detects the underwater rover's light and then turns on the LED lamp group. The COMS sensor of the underwater rover analyzes the light species of the LED light group and converts it into digital information. The underwater rover analyzes the digital signal to obtain its location. Each underwater beacon has an independent power generation component, which generates power by utilizing ocean current, greatly increasing the working time of the beacon. The LED lamp group gives positional information feedback through the light, which can reduce the system power consumption and increase the system working duration.

DETAILED DESCRIPTION

(7) The specific embodiments of the present invention are further described below in combination with the technical solutions and the accompanying drawings.

(8) A circuit connection of a submarine optical positioning beacon system with self-generating capability is shown in FIG. 2. The ISP interface 13, the COMS sensor 3, the LED lamp group 2 and the microprocessor 14 are directly connected, and the generator 10 and the battery 11 are directly connected. The electric energy generated by the generator 10 is stored in the battery 11, and then distributed to the COMS sensor 3 and the LED lamp group 2 by the microprocessor 14.

(9) The working steps of a submarine optical positioning beacon system with self-generating capability are as follows:

(10) First, the water quality assessment is performed on the active sea area where the target rover is to be located, and the optimal distance between the set beacons is determined accordingly. The program is downloaded by the ISP interface 13 of the underwater beacon A.sub.i, and the microprocessor 14 executes the program command to adjust and generate different PWM waves. Under the action of the PWM wave, the LED lamp group 2 can emit a specific color light, and the LED lamp groups 2 of different underwater beacons A.sub.i emit a specific color light or a specific plurality of color lights that carry positional information corresponding to the underwater beacon A.sub.i.

(11) As shown in FIG. 3a, when the program download is completed, three underwater beacons A.sub.i are fixed at the sea bottom 18, forming an array 1 of a plurality of underwater beacons A.sub.i. The underwater rover 17 with its own illuminating device and optical sensor moves within the array, and the underwater rover 17 always turns on the illuminating device during the movement. If the COMS sensor 3 of the underwater beacon A.sub.i does not detect the light of the underwater rover 17 (i.e. the underwater rover 17 is not in the vicinity of the underwater beacon A.sub.i), the LED lamp group 2 of the underwater beacon A.sub.i does not emit light.

(12) As shown in FIG. 3b, when the underwater rover 17 moves to the vicinity of a certain underwater beacon A.sub.i, the COMS sensor 3 of the underwater beacon A.sub.i detects the light of the underwater rover 17 and then sends a command to the microprocessor 14 to turn on the LED light group 2. The optical sensor of the underwater rover 17 analyzes the light species of the LED light group 2 of the underwater beacon A.sub.i and converts it into digital information, and the underwater rover 17 analyzes the digital signal to obtain its position.

(13) When the underwater rover 17 is away from a certain underwater beacon A.sub.i, the COMS sensor 3 of the underwater beacon A.sub.i turns off the LED light group 2 of the underwater beacon A.sub.i because the LED light of the underwater rover 17 is not detected;

(14) When the submarine current does not flow from the front surface of the runner 5, the deflector 16 will must be subjected to the thrust of the ocean current to drive the horizontal bracket 24, the generator 10 and the runner 5 to rotate together until the deflector 16 faces the ocean current again, reaching the balance of force and stopping rotating. At this time, the runner 5 will also faces the ocean current, and will rotate under the action of the ocean current. The runner 5 and the rotating core of the generator 10 are directly connected. When the runner 5 rotates, the rotating core of the generator 10 also rotates. The electric energy generated by the rotating core cutting the magnetic induction line is stored in the battery 11 through the cable 7.
