Description

technical field [0001] The invention relates to the field of marine environment information acquisition, in particular to a marine environment information submersible mark device based on a multi-parameter sensor. Background technique [0002] Marine environmental noise is not only the background noise interference field of various marine acoustic systems, but also carries a large amount of useful marine environmental information. Therefore, the study of marine environmental noise is of great significance in both civil and military applications. In order to improve the performance of underwater acoustic detection equipment, it is necessary to fully investigate and analyze the characteristics of marine environmental noise, and deeply understand the characteristics of time domain, frequency domain and air domain of marine environmental noise, which requires continuous measurement of marine environmental noise. With the development of vibration reduction and noise reduction tec...

Real-time transmission, data will be affected by sea conditions; self-contained data storage technology only stores the collected data without preliminary preprocessing

[0003] Chinese patent 201410030440.1 discloses a continuous measurement system for optical fiber temperature and depth submersible buoys. The system includes a communication schedule, a main float, an instrument cabin, a demodulation system, a temperature and depth chain, a cable, an acoustic releaser, and an anchor weight. The measured ocean temperature and depth information is transmitted to a remote computer through a communication buoy for real-time storage and processing through real-time transmission. The signal data collected by this real-time communication will be affected by the beating of waves and different floating objects on the sea level. The quality of the collected data is not good, with a lot of noise in it

This way of storing data is that the data of each sensor is stored separately, and it does not have the function of integrating and packaging and transmitting to a remote computer. Therefore, the data transmitted to the computer is scattered and scattered, and it is not easy to integrate and process within the same period of time. Data processing and analysis time longer
