Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The telemetry and remote control section installed on the underwater vehicle has a synchronous acoustic beacon, which can transmit acoustic signals to the buoy at regular intervals. At the same time, the telemetry and remote control section of the underwater vehicle also sends internal attitude information and working status information to the communication buoy. Multiple communication buoys form a long baseline system, use the Beidou receiver loaded on it to regularly measure its own position, receive the positioning signal emitted by the underwater vehicle, estimate the arrival time, and pass through the received vehicle attitude information and working status information together. Radio transmission to the mother ship. The mother ship comprehensively processes the radio received information, completes underwater target positioning and track estimation, and...

Abstract

The invention discloses a communication buoy for underwater acoustic positioning and a networking thereof. The communication buoy is connected with a comprehensive processing display control system, and comprises a buoy body, a underwater sound communication machine, a positioning system and a radio communication system; the buoy body provides water surface buoyancy support for the communication buoy; the positioning system and the radio communication system are located at the upper portion of the buoy body, and the positioning system is used for providing position information for the buoy; the radio communication system is used for sending data received by the underwater sound communication device to the comprehensive processing display control system; the radio communication system is further used for receiving a remote control command sent by the comprehensive processing display control system in real time, and sending the remote control command to the underwater sound communicationmachine; the underwater sound communication machine is located on the lower portion of the buoy body for receiving information transmitted by a underwater vehicle and transmitting the remote controlcommand to the underwater vehicle. The invention also provides the communication buoy networking for the underwater acoustic positioning, and the networking comprises at least three communication buoys for the underwater acoustic positioning.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to a communication buoy for underwater acoustic positioning and its networking. Background technique [0002] The ocean area is vast, the underwater detection environment is complex and harsh, and the equipment is difficult to operate. The development of underwater unmanned autonomous systems has become the mainstream direction of ocean detection. Intelligent underwater vehicles play an important role in national security and national economy. During the development process of underwater vehicles, they must undergo underwater tests to verify various functional indicators, including underwater three-dimensional track, navigation attitude, working Therefore, it is necessary to establish a telemetry system that can remotely measure the navigation trajectory, navigation attitude and working status information of the underwater vehicle, and at the same time perform remote wireless rem...
