Embodiment Construction

[0027] The technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0028] Figure 1 shows the basic conditions of the small-scale autonomous underwater navigation observation platform equipped with instruments and equipment. equipment, carrying GPS and satellite communication device 2 at the same time, GPS obtains the position information of the small underwater autonomous navigation observation platform through GPS antenna 3, and satellite communication device 2 sends the measured characteristic data with position information to the deck unit 7 on the release mother ship . CTD6 is installed on the head of the observation platform, and the sampling rate reaches 16-24Hz. The ADCP adopts the wideband ADCP with four-beam oblique orthogonal JANUS configuration, which can greatly reduce the interference caused by the tilt and sway of the carrier. Configure two sets of ADCP installed front and rear, one set is looking u...

Abstract

The invention discloses an observing method of a small-sized underwater autonomous navigation observing platform, and the observing method comprises the following technical steps of: measuring a ladder-shaped section and continuously measuring a sitting bottom. The method comprises the following steps of: autonomously navigating according to a ship route set by a deck unit; carrying out ladder-shaped section measurement; measuring an ocean current section, a temperature, a conductivity section and a water depth change; reaching to a set place and automatically sinking to carry out fixed point sitting bottom continuous measurement; measuring the ocean current section, a sea level, a sea bottom temperature and the conductivity; after finishing set measuring time, automatically floating up; and measuring in a returning process in a same manner and transmitting obtained data to the deck unit through a satellite communication device. According to the observing method of the small-sized underwater autonomous navigation observing platform, the requirements of an ocean observation standard are met by the ladder-shaped section measurement and the sitting bottom continuous measurement, so that the standardization and practical applicability of observed data are realized.

Description

technical field [0001] The invention relates to an ocean observation method, in particular to an observation method using a small underwater autonomous navigation observation platform. Background technique [0002] With the accelerated pace of exploring the ocean, people are increasingly aware that the ocean, which accounts for 75% of the earth's area, will become a new field for human survival and development, and will play an important role in human development and social progress. However, due to the complexity of the marine environment, people's understanding of the ocean is still very limited, and the methods for people to obtain ocean data are also limited. The technology of small-scale underwater autonomous navigation observation platform is a high-tech of marine environment observation. The underwater autonomous navigation observation platform is mainly used for unmanned, large-scale, long-term underwater environmental observation, and on-site close observation in m...
