Research And Implementation Of Orchard Monitoring System Based On Internet Of Thing

With the continuous improvement of information technology,Internet and hardware technology,the application of the Internet of Things in agriculture is becoming more and more common,and the depth and breadth of application are also deepening with the development of the Internet of Things.For example,the Internet of Things has temperature perception and intelligent control,dynamic monitoring of air and soil temperature and humidity,real-time monitoring of orchard environmental parameters,growth parameters,etc.A series of functions have played an important role and technical support for the daily maintenance and development of orchards.Because of this,the Internet of Things will be combined with the daily supervision of the orchard.Through the collection,screening and management of the effective information of the orchard,the corresponding environmental data required for the growth of fruit will be provided for the orchard managers,so that the managers can accurately obtain the temperature,humidity and other basic information in the garden,and improve the management of the orchard.Aiming at the above requirements,this paper combines ZigBee technology and NB IoT technology to complete the design and implementation of orchard monitoring system in the Internet of Things environment.This paper focuses on the orchard monitoring system under the Internet of Things,analyzes the specific needs of managers in the process of orchard monitoring,completes the composition of hardware and the realization of software,and further explores the application and future development advantages of the orchard monitoring system supported by the Internet of Things.The hardware of the orchard monitoring system supported by the Internet of Things technology consists of sensor nodes,gateway nodes and monitoring nodes.The sensor nodes,namely ZigBee nodes,are used to collect and sense data.The gateway nodes complete data exchange and protocol conversion,cooperate with the sensor nodes,and manage and analyze the temperature,humidity and wind speed information in the orchard through the monitoring nodes in the monitoring module.The basic composition of the monitoring module is the monitoring node,which is composed of the soil temperature and humidity sensing module,the air temperature and humidity sensing module,the wind speed sensing module,the GPS module,the microcontroller module and the optocoupler isolation module to complete the realization of the hardware system functions.In the orchard monitoring system supported by the Internet of Things technology,the design of the software part adopts the design idea of software engineering.Through the feasibility analysis of user needs,the general architecture and branch content of the orchard monitoring system are decomposed in detail,including the login/registration module,data monitoring module,orchard management and analysis module and abnormal alarm module.The login/registration module is mainly used to complete the user’s identity registration and login,and verify whether the login information entered by the user is correct.The data monitoring module mainly monitors the temperature,humidity data and wind speed data of soil and air collected by each node sensor of the orchard environment.The orchard management and analysis module is closely combined with the hardware components.The collected data is transmitted to the background database through sensors and monitoring module nodes.The system user can select the node location and time period to be monitored through mobile terminal devices such as mobile phones or computers to view the environmental data of the node location in the corresponding time period.The abnormal alarm module is mainly used to judge whether the preset temperature and humidity values are exceeded by reading the soil temperature and humidity,air temperature and humidity environmental data at different nodes of the orchard and comparing them with the preset temperature,humidity and other environmental data of the orchard.If the preset values are not exceeded,the data will be read and recorded normally.If the preset values are exceeded,the system will give an alarm and remind.Finally,complete the design of the database system,complete the E-R diagram design of the database and related form data.Finally,through system testing,the reliability and feasibility of the system are determined,so as to ensure that the orchard monitoring system designed in this paper can be realized and used.
