Multiple XBT (expendable bathythermograph) probe automatic throwing and measuring system

Abstract

The invention discloses a multiple XBT (expendable bathythermograph) probe automatic throwing and measuring system. A throwing mechanism automatically controls throwing of multiple XBT measuring probes, so that the probes measure the ocean temperature profile data in quick descending processes. The system is characterized in that a deck unit of the system comprises a fixed throwing frame, a data acquisition control box and a close range display terminal; the fixed throwing frame is formed by a base and a plurality of same single throwing devices; the fixed throwing frame and the close range display terminal are connected with the data acquisition control box by cables; the fixed throwing frame, the close range display terminal and the data acquisition control box cooperate jointly to complete detection of in-place statuses of the probes, execution of probe throwing actions and acquisition and transport of temperature profile measured data after the probes enter the water; an observation room unit of the system comprises a data processor and a control and real-time data processing module installed inside the data processor; and the observation room unit completes the processes of sending a control instruction to the data acquisition control box via a CAT5 outdoor Ethernet cable and processing the feedback information of the data acquisition control box, simultaneously receives, processes and stores the temperature profile measured data and draws curves, and can achieve data communication with an upper data center as required.

Description

technical field [0001] The invention relates to a device for measuring marine hydrological elements, in particular to a device for automatically controlling and placing a plurality of XBT probes to measure seawater temperature profiles. Background technique [0002] Seawater temperature profile data is one of the most basic marine environmental elements and a physical quantity reflecting the thermal status of seawater. The distribution and change of seawater temperature affect and restrict the changes of other hydrometeorological elements. The distribution of seawater temperature profile and its change with time directly affect the propagation speed and path change of underwater sound waves. The rapid acquisition of seawater temperature profile data can provide important assistance for marine surveys, marine scientific research, and marine development and utilization. [0003] The Expendable BathyThermograph (XBT) is a disposable measuring device that senses and measures th...
