Ocean element vertical section measuring device

Abstract

The invention provides a device for measuring vertical profiles of marine elements, including a data acquisition unit, a serial port communication unit, a single-chip microcomputer control unit, a storage unit, a limit switch unit, a mechanical execution unit, and a power supply unit; the data acquisition unit measures seawater temperature, For parameters such as salinity and depth, the collected parameters are uploaded to the single-chip control unit through the serial port communication unit; the parameters collected by the data acquisition unit are processed by the single-chip control unit and then sent to the storage unit by the SPI interface to save. The invention adopts C8051F340 and DC motor, combined with integrated sensor, serial port communication, switch relay and SD card storage technology, realizes the control of three states of pawl mechanism, one-way grasping, damping locking and free floating, and mass storage of measurement data. The readout of data is simple and easy, and the purpose of long-term, fixed-point and continuous collection of marine elements at various levels underwater is realized.

Description

technical field [0001] The invention relates to the technical field of ocean detection, in particular to a device for measuring vertical profiles of ocean elements. Background technique [0002] Detection technology is one of the key factors to promote the gradual maturity of marine science. Marine science spans dozens of orders of magnitude in time and space, from physics, biology to geology, from sea-air exchange to ocean profile water bodies. At present, with the development of detection technology, the marine data acquisition method on which the development of marine science depends is changing from "investigation" to "detection", and the monitoring of marine environment has entered into the comprehensive monitoring of the marine environment from space, coast, water surface and underwater. , The era of all-weather three-dimensional monitoring. However, at present, most of my country's marine environmental monitoring technology still relies on ship observation and statio...

AI Technical Summary

Problems solved by technology

However, at present, most of my country's marine environmental monitoring technology still relies on ship observation and station observation technology to periodically collect elemental data of the ocean surface or some limited water layers, and data on the ocean subsurface and deep underwater are very scarce.

With the improvement of people's demand for marine science cognition, it is difficult to gain an in-depth understanding of the physical, biological, and chemical environments in my country's vast sea areas by relying only on the elemental data of the surface layer or limited water layer, and cannot satisfy all-round three-dimensional monitoring Requirements, can not meet the needs of my country's marine economic development
