Audited Supplier
It is equipped with a high-sensitivity hydrophone array and underwater acoustic signal acquisition and processing unit, through signal acquisition, amplification and filtering technology, to obtain real-time data of acoustic wave signals hundreds of meters below the sea surface. Buoy data can be returned to the cloud platform in near real-time by Beidou, Iridium and other means, and users can easily access, query and load data.
The series of buoys has the characteristics of high acoustic monitoring sensitivity, low self-noise and low power consumption, and can be used in the fields of ocean background noise monitoring, ocean engineering noise assessment, surface ship noise, underwater target radiation noise, marine organisms' vocalization and acoustic tracking of marine mammals.
Functional Characteristics
Broadband Monitoring of Underwater Noise
The system is equipped with broadband digital hydrophone and noise recorder, and the general monitoring frequency is 20Hz~20kHz (optional 20Hz~160kHz), which can cover all kinds of sounds in the underwater environment.
Support Underwater Acoustic Vertical Array
It is equipped with a vertical linear array of hydrophones to support underwater acoustic profile monitoring within 500m depth, which has advantages of high gain and strong directivity compared with a single node.
Multiple Ways of Real-time Communication
The monitoring data can be transmitted back to the client or the cloud MEINS data management platform in real time through various means such as Beidou and Iridium.
High Level Power and Long Battery Life
It comes with a large-capacity energy storage unit, and is equipped with a 42W solar charging module for more lasting battery life.

Yantai Kekan Ocean Technology Co., Ltd. is a technology-based small and medium-sized enterprise that integrates the researchand production of marine observation and monitoring equipment, marine environmental services,and the development of key supporting systems for marine engineering. Adhering to the spirit of "scientfic management and exploration of the deep sea", it focuses on the research and development of intelligent marine observation and monitoring equipment and the safety guarantee of offshore engineering.
The R&D team of the company is led by Professor You Zajin, an academician of the European Academy of Sciences. He has been engaged in research on ocean dynamics, numerical model construction,and has led projects funded by the Natonal Young Scholars Fund, the Ministry of Sclence and Technology's key R&D project, the National Key Fund, and multiple Australian Key Fund projects.The core personnel of the team also include multiple doctoral and high-end managemert talents in the marine field, with complementary professional backgrounds and a solid foundation for cooperation. They have jointy cariedout muliple related projects/research projects and possess the strength of product design, manufacturing, and sales. Since its establishment, the company has applied for more than 30 patents and softworks, of which 13 have been authorized, possessing exclusive intellectual property rights and strong technical barriers.
The company's main products are intelligent marine environmental element observation and monitoring equipment and high-precision early warning and forecasting system, among which the intelligent observation and monitoring equipment has the function of self-positioning, which can adjust the positioning based on real-time sea conditions and relying on low-power power system; The submarine winch has the advantages of small size, strong traction and good sealing, which can better adapt to the complexity of the seabed work; The high-precision marine hydrological element early warning and prediction system provides wave, tide, storm surge and sediment transport data, solves the problems of unclear physical mechanism and low simulation accuracy of current numerical simulaton, and can provide a solid guarantee for marine enginering.
