Abstract

The invention discloses a bottom-water temperature detection system, which comprises a power supply, a host and an underwater temperature sensor array, wherein the underwater temperature sensor array comprises a plurality of digital temperature sensors located in sea water; all the digital temperature sensors are respectively located at different depth in sea water; the host is connected with the underwater temperature sensor array in a single-bus three-wire system manner; the single-bus three-wire system manner refers to that the host and the underwater temperature sensor array communicate by adopting a bus; a working power supply is obtained by each digital temperature sensor from a data line; the host gives a command through the bus to start the underwater temperature sensors to begin to detect the temperature, and the temperature data collected by the underwater temperature sensors is read through the bus to realize detection on bottom-water temperature at different depth. The bottom-water temperature detection system is easy to implement, high in temperature detection accuracy and good in anti-interference performance.

Description

technical field [0001] The invention relates to a seabed temperature detection system. Background technique [0002] The ocean accounts for three quarters of the total area of ​​the world, and is closely related to the living environment of human beings. Seawater temperature, as an important parameter of ocean water temperature, has special significance in ocean monitoring, national defense construction and scientific research. For this reason, people have designed various A form of seawater temperature measuring instrument. At present, there are various means of obtaining seawater temperature information, such as satellites, aircraft, ships, buoys, shore-based monitoring stations, fixed offshore platforms, volunteer ships, and so on. Ocean temperature measurement plays an important role in the arrangement of other submarine instruments and the investigation of the research environment. The existing seawater temperature measuring device has large volume, high cost and is n...
