Description

Self-adaptive environment sensing and multi-mode switching control system and method for floating black box Technical Field The invention relates to the technical field of aerospace safety, in particular to a self-adaptive environment sensing and multi-mode switching control system and method of a floating black box. Background The black box (the flight data recorder FDR and the cockpit voice recorder CVR) is a key device for recovering true phase and analyzing accident causes in the air accident investigation. However, in the existing aviation security system, there is a significant technical bottleneck in designing a black box for an offshore air accident, so that in a deep-sea air accident event such as MH370, search and rescue work often falls into a dead office. The main problems existing in the prior art are as follows: The positioning limitation of the "submerged" design is that current standard black boxes are designed to sink into the sea floor with aircraft debris. The deep sea environment is accompanied by a huge hydrostatic pressure and can seriously obstruct the transmission of radio signals. The search and rescue personnel mainly rely on an underwater sonar beacon (ULB) sent by a black box to carry out sound wave positioning. However, the acoustic waves travel extremely limited distances (typically only a few kilometers) in complex thermocline and salinity layers and are extremely easily obscured by the seabed terrain, resulting in extremely low search and rescue efficiency. The time window for energy delivery limits that existing underwater positioning beacons are powered by built-in lithium batteries, which typically have standard operating times of only 30 to 90 days. Once the battery is depleted, the black box will lose its ability to communicate with the outside and become a piece of "dead iron" on the ocean floor, causing the risk of permanent loss of precious flight data. The vision and radar features are weak-although the black box is painted in a striking orange color, it is small in volume (typically as the shoe box size) on a wide and rough sea surface. For an aerial search and rescue airplane or satellite radar, the difficulty of identifying the tiny nonmetallic reflection source is extremely high under the huge sea surface background clutter. The prior equipment regards the ocean as a simple 'physical medium', aims at resisting the corrosion and pressure of the sea, and does not consider how to actively enhance the discovery probability of the equipment by utilizing rich biological resources (such as shoal of fish and plankton) in the ocean, so that the self-adaptive environment sensing and multi-mode switching control system and method of the floating black box are designed. Disclosure of Invention The invention aims to provide a self-adaptive environment sensing and multi-mode switching control system and method of a floating black box, which are used for solving the problems in the background technology. In order to achieve the above purpose, the invention aims to provide a self-adaptive environment sensing and multi-mode switching control system of a floating black box, which comprises an environment sensing module, a switching module and a switching module, wherein the environment sensing module is used for acquiring multidimensional physical information of an environment where the black box is located in real time. The central control module is in communication connection with the environment sensing module and comprises a mode decision unit and a fault tolerance processing unit, and is used for judging the current environment state based on the multidimensional physical information and outputting corresponding working mode control instructions according to a preset strategy model, wherein the instructions at least comprise instructions for triggering automatic separation, starting biological induction and switching working modes. And the mode execution module is in communication connection with the central control module and is used for receiving the control instruction and executing positioning, communication, biological induction and mechanical separation operations corresponding to the working mode. And the energy management module is electrically connected with the central control module and the mode execution module and is used for providing a matched energy scheduling strategy for each module according to the current working mode. As a further improvement of the technical scheme, the environment sensing module comprises a water pressure detection unit, an environment light detection unit and a motion state detection unit. The water pressure detection unit is used for monitoring the external water pressure information of the black box, and the output of the water pressure detection unit is used as a main criterion for triggering the mechanical separation unit. And the ambient light detection unit is used for monitoring the illumination intensity information of the exte
