The specific embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.Following examples will contribute to those skilled in the art further to understand the utility model, but not limit in any form the utility model.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection domain of the present utility model.
The Watership Down attitude measurement system provided according to the utility model, comprise main control system, sonar feedway, sonar receiving device, Underwater Optical terminal, optical fiber, optical transmitter and receiver waterborne, mounting rod, mounting rod drive motor, telltale, instrumentation ship, GPS module, wherein, described sonar feedway connects described main control system, described sonar receiving device, Underwater Optical terminal, optical fiber, optical transmitter and receiver waterborne, main control system connect successively, described sonar feedway is installed on described mounting rod, and described mounting rod drive motor connects described main control system.Described telltale connects described main control system.Described main control system is arranged on described instrumentation ship, and described mounting rod is arranged at the shipboard side of a ship of described instrumentation ship.Described GPS module is installed on the top of described mounting rod.
More specifically, acoustic reflection, to assigned direction emission high frequency wave beam, when wave beam arrives obstacle, occurs in the sonar feedway, backward wave is finally received by the sonar receiving device, in this process, distance during according to measured acoustic velocity and transmitting/receiving, calculate the distance of transmitting/receiving to obstacle, via software, these range data are integrated again, draw out the 3D exterior view, and carry out paintedly according to the distance size, finally generate the color three dimension stereo-picture.The sonar feedway adopts the mounting rod carry, and mounting rod fixedly is placed in to the shipboard side of a ship.In the exploration process, regulate the downrange angle of sonar by the electronic control of mounting rod, to meet the side of sweeping of different angles.After installation, surveyed front debugging, to obtain the relevant sound velocity curve in current waters, and suitable emission angle, predetermined depth.After debugging, according to the shipwreck place approximate location that early stage, side-scan sonar provided, surveyed.
In a preferred specific embodiment, the utility model has been realized the attitude measurement to harbour, Zhoushan shipwreck.The reasons such as the harbour, Zhoushan is positioned at marine site, the East Sea, and port internal cause ship dealing is frequent, silt is more, water quality is poor, and visbility is very low.Its depth of water does not wait at 80-90 rice.The target shipwreck waits reason to sink in June, 2010 because of maintenance not in time.First adopt side-scan sonar to carry out the estimation of location and other parameters to surveying the shipwreck target, draw following information:
