Underwater towing operation width automatic monitoring system

The utility model discloses an underwater towing operation width automatic monitoring system, which comprises two parts, namely a console and a photoelectric measurement device respectively. The console is arranged in a monitoring chamber and is in the form of a manual operation and display device composed of a general-purpose computer system and used for operators to operate the photoelectric measurement device and automatically calculate the operation width. The photoelectric measurement device is arranged at the high part of the mast of an unmanned distance-control boat and no object is arranged in the measurement direction of the photoelectric measurement device. The photoelectric measurement device is composed of a first shell, a visible-light camera, an infrared camera, a laser range finder and a rotation platform. The photoelectric measurement device is capable of photographing an indication buoyancy aid on the water surface in real time and monitoring the locus of the object in real time. The console and the photoelectric measurement device are in communication with each other through a radio station. By means of the system, the all-weather measurement is realized in electromagnetic-interference conditions or blackout conditions. The system is high in anti-interference capability, high in passive detection accuracy and high in data accuracy.
