Design And Implementation Of Aquaculture Environment Monitoring System Based On Internet Of Things

China is a big agricultural country.At the same time,agriculture is related to the livelihood of billions of people.It is a strategic issue of great significance to study how Internet of Things technology can play its role in animal husbandry,planting,aquatic products,forestry and other sub-fields in the agricultural field.In this context,this paper,starting from the problems existing in animal husbandry,an important branch of the agricultural field,puts forward a set of intelligent environmental monitoring and control scheme based on Internet of Things technology,which is suitable for various agricultural fields through in-depth study and research on the basis of previous studies.This paper analyses the production characteristics of aquaculture farms,and determines that the monitoring objects are temperature,humidity,ammonia concentration,lightling,fan and other equipment and environmental factors.It realizes the powerful functions of real-time environmental monitoring,issuing control commands,data preservation and export,data chart display,environmental indicators exceeding the limit of early warning,notification of alarm short messages,map location of aquaculture base,unlimited distribution of authority,etc.The system runs in the cloud.Users only need to use authorized account to login in the browser without installing software.The system is divided into operation mode and management mode according to different account permissions.A set of system can be distributed to multiple users for use.Super administrator controls the maintenance of the whole system.The system consists of STM32 chip,GPRS module,sensing element,relay,extended reserved interface,software platform and other modules.In addition,STM32F103C8T6 is used as the main control chip in the hardware of the system.The software platform is developed based on JDK1.8.MySQL and Redis are used as the database.In this paper,the focus is on the real-time monitoring of environmental factors,cloud characteristics of the platform,robustness of communication messages,concurrency of software systems,portability of application scenarios,stability of hardware equipment and other aspects.Especially,a lot of research has been done on the portability and scalability of the system.The software platform has reserved interfaces for various agricultural scenarios,so that the system has the ability to seamlessly transplant to other agricultural production areas besides animal husbandry.Users only need to develop different hardware devices according to the actual situation of the application scenario and the agreed communication protocol,and the software platform does not need to make any changes.For the purpose of enhancing scalability,the system also has the function of compatible with a variety of communication protocols,which can be adapted to WIFI,GPRS,and other communication protocols.The system has strong concurrency,and can support more than 10,000 hardware devices online at the same time through single-machine deployment.In this paper,the detailed on-line inspection and testing of the functional modules of the system have been proposed,and all the functions of the system design have been verified.Furthermore,the whole system has the characteristics of easy deployment,easy operation,low cost,high concurrency and scalability.It is also an excellent design scheme of the aquaculture environment measurement and control system,which has certain application value.
