Research On Farmland Intrusion And Environmental Monitoring System Based On 4G

Traditional agricultural production technology has been unable to meet the food demand of the present society,so how to increase the food production has become a hot topic.At the same time,gradually increasing Internet of Things technology has been widely applied to agricultural production.It is an inevitable trend of agricultural development in the future to combine advanced Internet of Things technology with agricultural production.Therefore,this paper combines Internet of Things technology with intrusion monitoring technology and proposes a farmland intrusion and environmental monitoring system based on 4G.This design uses sensor technology,cloud platform technology and 4G wireless transmission technology to complete the collection of farmland target environmental information.First of all,for the quality of the invasive monitoring will JY901S acceleration sensor arrangement in monitoring the edges of the farmland area,when there is action item land enters the monitoring area of the farmland,change signal acquisition module of acceleration and Angle,study,because in the outdoor environment,there is a noise signal,will lead to false alarm system,Therefore,Kalman filtering and noise reduction method should be used to de-noise the data.After that,the type of acceleration signal should be identified through fuzzy recognition to determine whether to alarm and to choose whether to turn on the OV2640 camera.Secondly,for the environmental monitoring part,DHT11 temperature and humidity sensor module,FC28 soil moisture sensor module,soil pH sensor detection module and light intensity sensor detection module are added into the system to collect the corresponding environmental data in the farmland.Finally,in the OneNET cloud platform to view the data changes in the farmland.After testing,the system can well monitor the corresponding acceleration change data and Angle change data,but also can identify the type of acceleration signal.When the identification of abnormal circumstances,the system can be timely alarm.Secondly,the system can activate the O V2640 camera module immediately when the command of capturing is sent from the client,so as to capture the invaded area of farmland.In the cloud platform,the environmental temperature and humidity,soil moisture,soil pH value,light intensity and other data in the farmland can be checked accurately and timely,which has completed the initial design principles and objectives of the system.Figure[55]table[3]reference[79]...
