Airplane black box locating and searching sonar equipment

Abstract

The invention belongs to the field of locating and searching sonar equipment, and in particular relates to an airplane black box locating and searching sonar equipment comprising a combined search sonar array, a real-time information processing sub-system and a search sonar main control system. The combined search sonar array, the real-time information processing sub-system and the search sonar main control system are installed on a search platform, so that monitoring, direction-finding and accurate locating of a black box acoustic beacon signal can be sequentially achieved in real time, and meanwhile navigation information can be provided for the search platform, so that a black box can be quickly and effectively searched. The airplane black box locating and searching sonar equipment provided by the invention is applicable to quickly searching the airplane black box at an initial phase after an airplane is crashed in the water, can be installed on an underwater vehicle for use in a deep sea water area, also can be installed on a surface ship in a shallow water area for searching, and is strong specificity, rich in function and strong in platform adaptation; meanwhile, the detecting work, locating work and searching work of the sonar equipment are completed by using a set of equipment, the collaborative search capacity is stronger, and the search success rate is higher.

Description

technical field [0001] The invention belongs to the field of positioning and searching sonar equipment, and in particular relates to a positioning and searching sonar equipment of an aircraft black box. Background technique [0002] During the search for a plane crashed at sea, the targets to be searched mainly include the black box of the plane and the wreckage. Timely and effective use of the black box acoustic beacon signal, and the use of special sonar equipment to accurately locate and search the black box during the one-month life cycle of the black box acoustic beacon are the key to the successful underwater search of the crashed aircraft. However, in the past accidents involving plane crashes at sea, the overall search results were not good. Taking the search of Malaysia Airlines MH370 as an example, although it took 1046 days of surface and underwater search work, and my country's "Sea Xun 01" used The imported sonar detected a suspected black box acoustic beacon si...
