  • Publication number: 20200189706
    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.
