Intelligent Greenhouse Monitoring System Based On IOT Technology

With the rapid development of the national economy.lnternet of things technology has been widely used in people's daily life.For example.There is no doubt that smart home.intelligent transportation and intelligent logistics system are application of Internet of things technology in the society.Another huge system of IOT is agricultural IOT.what's more,The rapid development of cloud technology and embedded technology pushs agricultural informatization to a new peak.As the scale of agriculture production continues to increase and agricultural products in the greenhouse breed more and more varieties.the scale is also growing.Most of the operations of the traditional agricultural greenhouse are carried out in the artificial situation,for a large number of agricultural greenhouse,or a large area of agricultural greenhouse appears to be limited.According to the infrastructure of Internet of things,this paper designs a set of intelligent agricultural shed monitoring system based on Internet of things technology,and builds the monitoring system model base on three-layer architecture of perception layer,network layer and application layer.it determins the scheme conbining WiFi and cloud server.The design of intelligent greenhouse monitoring system mainly includes perceptual layer,network layer and application layer.The perceptual layer of intelligent greenhouse nonitoring system mainly realizes information collection and equipment control.In this paper,the hardware circuit design of the control chip,information acquisition and execution equipment of the perception layer is carried out respectively,including the selection and circuit design of MCU,the air temperature and humidity sensor,the illumination sensor,the soil moisture sensor and raindrop sensor.it also includes the design of alarm circuit and the drive circuit design of fan,lamp.humidifler.electroimagnetic water valve,shade,ceiling.what's more,it develops the collection,control and alarm of the corresponding procedures.The network layer of intelligent greenhouse monitoring system mainly completes the Communication between the equipment and the server.The paper designs the network communication system based on WIFI module and intelligent cloud server,which can realize remote and local monitoring combined with the upper computer mobile phone client.Considering that the mobile phone has no network,this paper also designs the Bluetooth communication function,which can be used to connect the system to achieve close monitoring.The application layer design of intelligent greenhouse monitoring system is mainly used for human-computer interaction.In this paper,an intelligent greenhouse monitoring system APP upper computer software is developed,which can query the real-time information and historical information of the intelligent greenhouse sensor through the operation interface.lt can also control the fan,lamp,humidifier,electromagnetic water,valve,shade,ceiling and other equipment in the shed.The system is equipped with a 200W pixel webcam,the intelligent greenhouse monitoring system app can directly call the camera to view the image information inside the greenbouse.The software also has the automatic check update,the user registration,the password retrieval,the mailbox information alarn,the software self-sharing,the information push and the voice inquiry function.The system is convenient and effective for monitoring and controlling the environment of agricultural greenhouse.Improving the utilization rate of resources and the level of agricultural production can provide a theoretical basis for the development of agricultural modernization in China.
