Deteriorating marine ecological environment has brought severe challenges to the development of traditional fisheries.In order to meet the growing demand of people for seafood,deep-sea cage culture technology has been rapidly developed with the support of relevant state departments.However,due to natural disasters such as red tides and environmental pollution,water changes have caused a large number of products to die,causing huge economic losses to fishermen.Thus,this paper,water quality environmental monitoring equipment to study deep-sea cage aquaculture,by reading the relevant literature,learned of similar equipment at home and abroad features a single,large power consumption,deploy and difficult to maintain,and expensive,does not apply to domestic deep-sea cage culture the status quo.For these problems,the design quality of the deep-sea cage culture area and environment monitoring system based on a wireless bridge and ZigBee technology,the realization of the temperature of each monitor node in the deep water area cage culture,PH,dissolved oxygen,salt Degree and other information and real-time acquisition,remote transmission,display and other functions of underwater water surface real-time video image data,combined with the master MCU sleep mode and adaptive adjustment node sampling period algorithm method,reduce node power consumption,and achieve extended system use The effect of the cycle.First,this paper determines the overall design of the system,and carries out detailed design and implementation from three aspects: data transmission network,the system hardware and the system software.By comparing different data transmission schemes and combining the on-site environment of Beihai fishery,the data transmission network and system communication protocol are determined.The system hardware is mainly for detailed circuit design of the water quality data acquisition module and the data convergence center module.The system software is mainly designed and implemented in two aspects of embedded software and shore-based monitoring terminal software.It’s time to debug the system after completing the design and implementation of each module of the system.Because the North Sea fishing grounds are still under construction,field testing can not be performed,so the relevant tests were carried out in the laboratory and outdoors.The test results show that the system can realize the collection,remote transmission and real-time display of water quality and video image data of each monitoring node.The water quality data acquisition error is within 2.16%,and the precision meets the requirements.The low power consumption design can effectively extend the node power cycle.The system meets all design specifications and will be used in the construction of the North Sea fishery in the future.
