Embodiment Construction

[0037] The invention provides a deep-sea compass system, such as figure 1 As shown, it includes a casing, a power module arranged inside the casing, a system board, an IF conversion board, an adapter board and a motion sensor, and external supporting equipment arranged outside the casing.

[0038] The casing includes a cover cylinder, a base and a sealing flange connecting the cover cylinder and the base. A sealed cable outlet is installed on the base. The power cables and communication cables from the adapter board and the system board are led out of the shell through the sealed cable outlet, the power cables are connected to the external power supply, and the communication cables are connected to the external supporting equipment.

[0039] The IF conversion board, power module, system board and motion sensor are all connected to the interposer board.

[0040] The motion sensor includes three gyroscopes and three accelerometers, and the motion sensor is mounted on the base ...

Abstract

A deep-sea compass system is disclosed. The system can provide accurate navigation information for safe, reliable and long-endurance operation of deep diving submersibles. An IF conversion plate, a power supply module, a system board and a motion sensor are separately connected to a patch panel. The motion sensor includes gyroscopes and accelerometers for three directions. Data generated by the gyroscopes are transmitted to the system board in a message form through the patch panel. Current generated by the accelerometers enters the IF conversion plate through the patch panel, is converted into frequency pulse signals and is then transmitted to the system board through the patch panel. A core plate stores collected original information, a navigation resolving result and system working state information into an SD card memory module. The core plate controls a USB reading module to read the information stored in the SD card according to requirements of program running or an outside command received from system external input-output interfaces.

Description

technical field [0001] The invention belongs to the technical field of deep-sea inertial navigation, and in particular relates to a navigation method using a deep-sea compass system. Background technique [0002] The deep sea contains abundant strategic resources and energy. New resources such as oil and gas, polymetallic nodules, cobalt-rich crusts, polymetallic sulfides, and natural gas hydrates have important scientific research and commercial application prospects, and are known as strategic alternative energy sources for sustainable development of mankind in the 21st century. [0003] Deep-sea biological genetic resources are new resources that have attracted international attention in recent years, and have broad application prospects in the fields of medicine development, gene therapy, and environmental protection. [0004] Deep-sea technology is an important technical guarantee for the realization of the national marine science and technology strategy. The level of ...
