Problems solved by technology

However, the resistance value of the temperature sensor in the probe is collected by the water surface acquisition system, and the ocean depth data is obtained by estimating the descent time of the probe. The accuracy of the depth data obtained is not enough, and the repeatability and consistency are also poor.

Abstract

The invention discloses a data acquisition device, a detection device and a system. The system comprises a detection device, a releasing device and an upper computer. Parallel communication sampling data is adopted between the releasing device and the detection device; the releasing device is used for connecting to the detection device and the upper computer; the detection device is used for obtaining pressure signals and temperature signals and converting the pressure signals and the temperature signals to first digital signals and second digital signals to transmit signals to the upper computer after signal amplification; the upper computer is used for receiving the first digital signals and the second digital signals which are transmitted by the detection device; and the sea temperature profile graph is drawn according to the first digital signals and the second digital signals. In the invention, the multi-core cable is utilized in order to transmit the data collected by the temperature detection device to the upper computer in a manner of parallel communication so as to solve the problem that the sea depth is needed to be measured through estimating the falling time of the probe, and the falling speed and the throwing mode of the probe are not limited.

Description

technical field [0001] The invention relates to the technical field of marine environment information monitoring, in particular to a data acquisition device, a detection device and a system. Background technique [0002] The expendable bathythermograph (XBT for short) can quickly obtain the ocean temperature profile without affecting the ship's navigation status, and is used to solve the problem of marine environmental parameter measurement when the ship is maneuvering. It is a very important measurement equipment and measurement method for underwater acoustic detection and other aspects. [0003] XBT is mainly composed of attitude control components, temperature sensors, signal transmission lines, etc. The attitude control part on the probe makes the probe descend in the sea water according to certain rules. After launching the XBT, when the probe reaches the sea surface, the timer on the data acquisition board starts counting, so that the depth value of the probe in the ...
