Manned submersible emergency navigation controller

Abstract

The invention relates to a manned submersible emergency navigation controller installed in a manned submersible manned cabin and a manned cabin external electronic cabin, and forming a manned submersible navigation control system together with a main navigation control system. A core circuit of the controller is composed of an embedded controller, an A / D, a D / A, an operational amplifier, etc. A circuit board in the manned cabin is used for acquiring and processing signals of a joystick on a control box; a circuit board in the electronic cabin is used for analyzing control instructions and outputting propeller control signals; and two circuits communicate with each other through a cabin penetration watertight cable. When the main navigation control system of a submersible breaks down, the emergency navigation controller can be switched to perform emergency navigation control on the submersible, thereby guaranteeing a basic navigation motion capability of the submersible and realizing safe course reversal.

Description

technical field [0001] The invention relates to the field of manned submersible control, in particular to an emergency navigation controller for a manned submersible. Background technique [0002] The manned submersible is used to realize manned navigation, scientific research, exploration operations and other work under water. There is no cable connection between the underwater operation and the mother ship. In order to realize the movement and navigation of the submersible in water, there are multiple propellers arranged outside the submersible, and the multi-degree-of-freedom movement of the submersible can be realized through the combined control of the propellers. The submersible controls the movement of the submersible by manipulating the joystick on the navigation control box in the manned cabin. Because the industrial control computer has the characteristics of fast calculation speed and can integrate the feedback data of other sensors to realize complex motion cont...

AI Technical Summary

Problems solved by technology

Due to the particularity of the application environment of manned submersibles, as the diving depth and water pressure increase, the failure risk factors of the external equipment of the submersible will increase accordingly. Without an emergency control plan, the submersible will face a huge risk due to loss of movement ability, unable to avoid obstacles, unable to approach the mother ship for motorized recovery, etc.

In order to ensure the safety of manned submersibles operating underwater, a single navigation control method cannot meet the high reliability control requirements of manned submersibles
