Application Of Internet Of Things In Orchard Monitoring And Alarm

With the continuous advancement of science and technology,the Internet of Things technology is maturing,and modern agriculture is gradually moving toward precision agriculture.Compared with traditional orchard environmental monitoring,the modern orchard environment monitoring method based on Internet of Things technology is cost and easy to use.,convenience and real-time aspects have great advantages and progress.Therefore,research on orchard environmental monitoring and alarm system based on Internet of Things technology has important value in actual production.This paper researches and develops a 4G network-based orchard environment monitoring and alarm system,which is real-time,accurate and convenient.It can support multiple users to access and view data,and freely configure alarm thresholds.The main work of the thesis includes:(1)The paper firstly carried out the architecture design of the orchard environmental monitoring and alarm system,which is divided into data acquisition module,data service module and system management module.The data acquisition module uses the environmental monitoring hardware equipment to collect temperature,humidity and illumination in real time.The environmental element information is uploaded to the server and saved to the database.The data service module displays environmental monitoring information and trends through a graphical interface,and provides data downloading functions.The system management module mainly provides login personnel maintenance and environmental monitoring data permissions.Control and alarm threshold settings.(2)Introduced some related technologies,such as 4G,Java development technology,cloud platform,etc.,as well as hardware device information and configuration parameters.In order to provide the basis and basis for collecting the environmental information of the orchard,the environmental monitoring management platform was designed and developed to be deployed to the cloud platform,while ensuring reliable and quasi-real-time data transmission and persistence to the database,so that the subsequent alarm function can work normally.(3)In order to ensure the normal use of the alarm function,multi-threading technology is applied on the server side,and various scenarios and optimizations are implemented on the alarm function.The alarm threshold can be flexibly set,and the single-value alarm can be set,and the interval can also be set.The value alarm and the alarm function are tested.The result shows that the system can send the alarm information to the specified recipient in time after triggering the alarm to achieve the effect and purpose of the warning.
