Study On Iot Technology In Strawberry Greenhouse Cultivation And Marketing

In recent years,the Internet of Things(IOT)emerged as a new network technology with the renewal of science and information technology and the development of network communication.Agricultural products and the Internet through wireless sensors,infrared sensors,radio frequency identification technology and other information sensing devices were connected via IOT,and IOT was used for real-time data communication and information exchange to realize intelligent identification,tracking,monitoring and management of agricultural products.In this paper,four strawberry planting areas were investigated,the application of Internet of things technology in strawberry greenhouse cultivation and sales was analyzed,and the existing problems were analyzed,and the solutions were put forward.The main results were as follows:(1)Based on the analyses of literature,this paper put forward the environmental application mode of strawberry IOT from the concept and development of Internet of things technology,the current situation of agricultural Internet of Things research and the problems existing in traditional strawberry production.(2)In strawberry cultivation,the most suitable environmental conditions(temperature,light,humidity,carbon dioxide,etc.)were analyzed for strawberry growth in greenhouse,set the threshold,and built the strawberry Internet of things planting system.The environmental information sensor collection equipment is connected with the Internet.Each monitoring node in the greenhouse is equipped with air temperature and humidity sensor,soil temperature sensor,soil moisture content sensor,carbon dioxide concentration sensor,illumination sensor,etc.At the same time,the planting area is also equipped with automatic irrigation system,automatic ventilation system,automatic sunshade system,etc.,and the collected data information are uploaded to the center data management and control platform through wired data transmission or wireless data transmission of environmental data collection equipment,and then collect the data to the computer monitoring terminal or smart phone,hand-held terminal,etc.,and then analyze the data information,so as to realize strawberry intelligent,labor-saving planting and automatic control management.For example,in summer sunny days of Dandong Shengye Berry Cooperative,the highest temperature data appears at 12:00noon,43.2 ?,and the lowest at 0:00 PM,14.3 ?;the highest air humidity data appears at0:00 PM,78.2%,and the lowest at 12:00 pm,42.3%;the highest soil temperature data appears at 12:00 pm,35.6 ?,and the lowest value appears.At 0:00 pm,the temperature is 18.2 ?;the highest carbon dioxide concentration is 428 mg/L,and the lowest is 189 mg/L.The environmental information sensor will collect data every five minutes.When the data of the corresponding module is collected,it will be transmitted to the application client through the transmission layer.The automatic control module of the application client will judge the current data according to the threshold range set in the system to decide whether the control equipment will be turned on or not.The monitoring center module includes video monitoring and production management client system,which is mainly used to record the plantinginformation and fertilization record of strawberry growing area.(3)In the circulation and sales of strawberries,through the analysis of the problems in the supply chain of strawberries transportation in China,the research on the traditional supply chain and the supply chain under the environment of the Internet of things is carried out.Starting from the traditional operation mode of supply chain,this paper puts forward the operation mode of fruit and vegetable supply chain under the environment of Internet of things,and puts forward the characteristics and specific application of fruit and vegetable supply chain under the environment of Internet of Things.In the process of strawberry sale,the traceability system of strawberry quality was established through the intelligent monitoring technology of internet of things.The fruit information was uploaded to the client in time and quickly.The important links of strawberry production,transportation,trade and consumption were traced in real time.The two-dimensional code and bar code were used to trace the source of strawberry.In the whole life cycle,the information of strawberry "document" was fully controlled.Farmers sold the strawberry fruit packaging through the IOT,and consumers could grasp strawberry fruit logistics information in real time through the monitoring system,so as to receive goods in time.(4)Through investigation and analysis,strawberry Internet of things has the following problems in cultivation and sales: in cultivation,professional equipment such as IOT sensors are expensive,data transmission is not accurate enough,the network is easy to be restricted by weather conditions,and information resources are lack of sharing;in strawberry sales,there are lack of industry standards,lack of ability of IOT technical service providers,complex coordination of sales supervision departments,and interests.The coordination mechanism is not perfect,the learning mechanism is not perfect and so on.It is suggested that the government should vigorously promote and promote the application of IOT in strawberry production,expand the utilization rate,improve the ability of IOT,sensor suppliers,improve equipment defects,reduce equipment costs,realize resource sharing,establish corresponding standardized management system,and build a perfect IOT sales platform.
