Intelligent Monitoring System Of Fisher Aquaculture Based On Internet Of Things

Due to the realization of China's industrialization,the structure of fishery culture has changed,which has transformed modern fishery farming into an intensive factory approach.In recent years,with the development and popularization of the technology of the Internet of things,the system of the Internet of things has its advantages in intelligent agriculture,smart home and so on.Therefore,based on the Internet of Things technology,this paper designs and develops a set of intelligent monitoring system for fishery aquaculture water environment.The system integrates data acquisition,automatic transmission,data processing,remote manual control and intelligent control decision-making.After analyzing the research status of fishery aquaculture monitoring system in China,the functions of the system are analyzed and designed from the perception layer,transmission layer and application layer respectively.Therefore,this article mainly works in the following aspects:(1)The hardware selection and design of the system are introduced in the perception layer,and the hardware circuit design of the acquisition board based on STM32 is completed.The physical framework of water quality sensor network was established to collect and record the water quality environmental parameters in aquaculture ponds.Aiming at the problem that sensors are easy to be polluted and damaged,an automatic sensor cleaning device is designed.(2)The network transport layer connects the sensor network with the monitoring center,and the collected water quality parameters are sent to the DTU module through RS232.The GPRS network is used to upload the data to the server for later data processing,storage and analysis.(3)The intelligent monitoring and management platform based on MySQL database is designed and developed in the terminal application layer,Users can log in the monitoring platform system through the Web page to view real-time information of the fishery aquaculture water quality system.At the same time,for the convenience of users,the mobile software platform of android system is designed and developed,which enables users to monitor water quality and environmental parameters anytime,anywhere and through multiple channels.Users can manually and remotely control the execution device from the client,The equipment can also be controlled and adjusted according to the processing results of the predictive control algorithm.The simulation results show that the predictive control algorithm can better adjust the dissolved oxygen concentration.The system can collect,transmit,store,display and adjust the parameters in the breeding environment.After long-term operation test,the system is in good working condition and no abnormal conditions have occurred,which can meet the basic requirements of fish farming.This system is a useful exploration of the technology of Internet of things in fishery culture,and it has a good prospect of popularization.
