SEMI-AUTO UNDERWATER VEHICLE'S TILT CAMERA EQUIPMENT FOR UNDERWATER MONITORING

摘要

PURPOSE: A tilt camera device for unmanned submarines is provided to be effectively operated over a long period of time with small energy as a size of the unmanned submarine and tilt camera are small. CONSTITUTION: A tilt camera device for unmanned submarines comprises a camera module (1), a tilt actuator (2), a camera encoder (3), a water depth sensor (4), an altitude sensor (5), a leak sensor (6), a power board (7), a monitoring board (8), a serial/Ethernet conversion board (9), an Ethernet hub board (10), and a pressure container (11). The camera module comprises a zoom function. The tilt actuator vertically rotates the camera module according to control signals. The camera encoder transmits signals from the camera module to the power board by converting the signals into Ethernet signals. The water depth sensor outputs analog signals in proportion to the water depth. The altitude sensor is detachably installed in a connector (5a). The leak sensor outputs on/off signals to sense leaking The power board supplies power being used for the sensors and camera module, and delivers serial communication signals to the monitoring board. The monitoring board transmits the serial communication signals to the serial/Ethernet conversion board, and treats input signals of the leak, water depth, and altitude sensors. The serial/Ethernet conversion board transmits the serial communication signals to the Ethernet hub board by converting the signals into Ethernet. The Ethernet hub board transmits the Ethernet signals to a main controller (20) of the unmanned submarine by switching the Ethernet signals The pressure container has watertight and pressure-resistant functions.
