Design Of Remote Monitoring System For Deep Sea Cage Aquaculture

Fast aquaculture development in our country in recent years,aquaculture has expanded gradually,the people’s demand for high quality aquatic products also increased gradually,and the traditional fish due to large farming area of concentration and density,and long-term accumulation of metabolites such as feed and fish is easy to cause water pollution effects of fish growth and reproduction.So under the relevant national policy support,access to high quality and high output of deep-sea fish aquaculture technology rapid development,but the Marine environment is complicated,the water quality of mutation breeding area can result in fish growth retardation and even death,and exist in the process of breeding criminals stealing behavior,these problems would give farmers bring huge economic losses,therefore,it is necessary to monitor the water quality of the breeding area and the surrounding environment.Aiming at the above problems,this paper designed a set of remote monitoring system for deep-sea cage culture,which helps users to realize remote real-time monitoring of water temperature,salinity,cage position and surrounding environment in deep-sea cage culture area.Firstly,the functional requirements of the system are determined according to the actual research situation of the breeding area,and the overall scheme of the system and data transmission scheme are designed.Secondly,determine the system hardware terminal design scheme,select low power SCM STM32L471 as the main controller,use hydrologic sensor,webcam and positioning module to complete the monitoring of all kinds of on-site information,through GPRS and 4G wireless communication technology to complete the remote transmission of monitoring data.Thirdly,determine the system software design scheme,complete the design of embedded software and shore-based monitoring terminal software,and develop a mobile APP to assist users to view on-site monitoring information and equipment management.Finally,the design of each functional module of the system is completed and the software and hardware are tested.The test results show that the monitoring system designed in this paper can realize the collection of water temperature,salinity,cage position and video image data in the breeding area,the wireless transmission function of data is normal,the power module can meet the daily power supply needs,and the mobile APP can check the on-site monitoring information in real time.In addition,the system can run stably for a long time,assist users to carry out remote monitoring of all kinds of information on breeding site,improve breeding production efficiency and risk prevention ability,and has a good application prospect.
