Automatic monitoring system for underwater dragging operation width

The invention provides an automatic monitoring system for an underwater dragging operation width. The automatic monitoring system is composed of a console and a photoelectric measuring device. The console is installed in a monitoring room and is a manual control and display device. The console is composed of a computer system and is used by operation personnel for remotely controlling and operating the photoelectric measuring device and also used for automatic calculation of the operation width. The photoelectric measuring device is installed at the high position, where blocking is avoided in the measurement direction, of a mast of an unmanned remote control boat. The photoelectric measuring device is composed of a first shell, a visible light camera, an infrared camera, a laser range finder and a rotating platform and can achieve real-time shooting of an indicating floating body on the water and monitor the path of a target. The console and the photoelectric measuring device are in communication through a wireless radio station. The automatic monitoring system can complete all-weather measurement under the condition of electromagnetic interference or a blackout and has the advantages that the interference resisting capacity is high, passive detection is conducted, and data precision is high.
