A device for forming an ultrasonic three-dimensional image of an unmanned ship monitoring area by using an orthogonal array

Abstract

Disclosed is an apparatus for forming a three-dimensional ultrasonic wave image of an unmanned vessel monitoring region by using an orthogonal array, comprising: two linear phased arrays (11, 12) perpendicular to each other and forming an orthogonal array, wherein the two linear phased arrays (11, 12) are respectively an emission linear phased array (11) used to send an ultrasonic wave and placed in an X-axis direction and a receiving linear phased array (12) used to receive an ultrasonic wave echo and placed in a Y-axis direction, and the two respectively have an interior unit; a right-angle ruler sensor with the length of one side being slightly less than λ / 2; a sender (20); a receiver (30); a collimated beamformer (40) performing a collimated beamforming operation on a digital signal provided by the receiver (30); an image signal processor (50); a display (60); a controller (70); a data storage portion (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.
