Device for forming unmanned ship monitoring area ultrasonic three-dimensional image by employing orthogonal array

Abstract

The invention discloses a device for forming unmanned ship monitoring area ultrasonic three-dimensional images by employing an orthogonal array. The device comprises two linear phase control arrays (11, 12) which are mutually vertical to form the orthogonal array, wherein the two linear phase control arrays comprise a transmitting linear phase control array (11) which is used for sending ultrasonic and is placed in the X-axis direction, and a receiving linear phase control array (12) which is used for echoing ultrasonic and is placed in the Y-axis direction, and each linear phase control array is equipped with an internal unit; a square sensor of which the length of one side is slightly less than lambda / 2; a sender (20); a receiver (30); a parallel beam shaper (40) which carries out parallel beam shaping operation on the digital signals provided by the receiver (30); an image signal processor (50); a display (60); a controller (70); a data storage part (180) and a three-dimensional image signal processor (190).

Description

technical field [0001] The invention relates to an imaging method for an unmanned ship monitoring area, in particular, it is formed by using an ultrasonic orthogonal array. Background technique [0002] Drones and self-driving cars have dominated the tech world, but the low-key unmanned ships are less well-known. In novels, unmanned ships are always shrouded in a sense of mystery. The famous "ghost ship" is the classic material of the writer's fictional voyage stories. technology. At present, unmanned ships are in a period of rapid development. However, unmanned ships still face many technical bottlenecks that have not been resolved before they are launched for trial voyage and when they are operating on the water.

Problems solved by technology

At present, unmanned ships are in a period of rapid development. However, unmanned ships still face many technical bottlenecks that have not been resolved before they are launched for trial voyage and when they are operating on the water.

[0003] Unmanned ships, as the name suggests, do not need human drivers to control them. Whether the emergence of the concept of "zero crew" is appropriate, there are different opinions in the industry. A reporter from the publication "Safety" once proposed the distance between the ideal and reality of "unmanned ships". It is proposed that if a ship suddenly catches fire and its location is unknown, according to the current level of technology, the operator of the unmanned ship will definitely give two instructions. One is the optimal method, that is, send a fire-fighting robot to find the exact fire point and extinguish it. The second is that if the robot cannot complete the fire extinguishing task, the ship will turn on the high-pressure water mist fire extinguishing system to complete the fire extinguishing task. There are two plans and one backup, which seem to have no defects, but there is one problem that cannot be avoided, even if the whole ship has Monitoring equipment, however, does not guarantee that the monitoring equipment has no blind spots. At this time, if a fire happens to be caught in the blind spot or is the source of the fire, neither of the two methods can be implemented. We can only watch the ship burn up and sink.
