Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] The near-water movement of UUV is a very important navigation state. Using the method of target guidance to make it track the mother ship of the test can greatly improve the autonomy of the vehicle in the process of deployment and recovery. Due to the characteristics of poor environment, high risk and strong uncertainty in offshore operations, it is necessary to use a variety of guidance devices and communication methods to obtain the position of the mother ship to improve the redundancy of the system. The present invention discloses a multi-channel guiding device and method for UUV to track a mother ship near the water surface, which is used to solve the problem that the UUV autonomously perceives the position of the mother ship and then realizes path tracking, wherein the multi-channel guiding device includes: 1) a traditional GPS positioning device , the work...

Abstract

The invention relates to a multi-way guiding device and a multi-way guiding method for near-surface tracking of a mother ship in navigation by a UUV (Unmanned Underwater Vehicle), which are suitable for solving the problem that the UUV can sense the position of the mother ship in severe environments. The multi-way guiding device comprises a GPS (Global positioning system), a marine laser range finder, a multi-beam forward looking sonar and a synchronous positioning sonar, wherein the GPS comprises GPS antennas which are respectively arranged on the UUV and the mother ship and used for receiving positioning information from a GPS satellite; the marine laser range finder is installed on the mother ship, and is used for measuring the relative distance between the UUV and the mother ship and the directions of the UUV and the mother ship through laser beams; the multi-beam forward looking sonar is installed on the UUV, and is used for measuring the relative distance between the UUV and the mother ship and the directions of the UUV and the mother ship through sound waves; the synchronous positioning sonar comprises a emission array installed on the mother ship, a receiving array and a transponder installed on the UUV. According to the guiding device, the redundancy capability and the positioning precision of the system are improved, and the system data transmission reliability is improved.

Description

technical field [0001] The invention relates to a multi-channel guiding device and method for UUV tracking a mother ship near the water surface, which are suitable for solving the problem of UUV sensing the position of a mother ship in harsh environments. Background technique [0002] The near-water movement of UUV is a very important navigation state. Using the method of target guidance to make it track the mother ship of the test can greatly improve the autonomy of the vehicle in the process of deployment and recovery. With the mother ship as the guidance target, on the basis of real-time position acquisition, the corresponding route can be planned and sent to the UUV, and then the autonomous tracking navigation can be completed. The traditional method is to equip the mother ship and the UUV carrier with a global positioning system, that is, a GPS device, to obtain the absolute position of the two expressed in latitude and longitude, and to complete the conversion of the r...
