Underwater camera unit with cable-controlled data transmission
The patent US12010463B2 describes an advanced underwater camera unit designed for efficient communication and operation in aquatic environments. The unit features a pressure housing that contains essential components such as a modem, command processor, image processor, camera sensor, and a power supply circuit. The modem plays a crucial role by multiplexing image data and control signals, allowing for the transmission of both through an underwater cable with two wires. This setup enables the camera unit to receive DC supply voltage and control signals while simultaneously sending back multiplexed image data. Additionally, the design includes provisions for light sources and sensors, enhancing the unit's functionality for monitoring and controlling various operations underwater.
The patent also outlines a surface controller that interfaces with the underwater camera unit via the same two-wire underwater cable. This controller is equipped with a power supply circuit, modem, and processor, which work together to manage the transmission of control signals and image data. The surface controller can de-multiplex incoming data, allowing for real-time monitoring and control of the underwater camera unit and any connected devices, such as pressure sensors for divers. The system's architecture, including the use of orthogonal frequency-division multiplexing (OFDM) for the modem, ensures robust communication capabilities, making it suitable for various underwater applications. Overall, the patent presents a comprehensive solution for underwater imaging and monitoring, emphasizing efficient data transmission and operational control.
