Design And Realization Of Information Platform Of Smart Park Based On IOT

With the development of the popular technologies such as IOT,cloud computing,big data and mobile network,the studies on smart city and smart park are carried on with high enthusiasm.The mankind is stepping into a new era of digitization and intelligence,when the intelligent management and service are changing our lives.Smart park is a significant manifestation and epitome of smart city.However,there are some problems such as unbalanced data pressure,lacking of sensing nodes,limited wireless sensing ability and insufficient analysis ability of unstructured data.Firstly,this paper analyzes the domestic and foreign research status.Through the requirement analysis,it ensures that the developing goal of the system is to meet the demands in green environmental protection,efficiency,convenience,security precaution and intelligent humanities.The following works are completed for this paper: 1)Based on the overall design of the information platform,the general technical and frameworks are proposed,and such components as transmission network and sensing system are subsequently designed;2)ZigBee is adopted to meet the collection and transmission demand of mass data,which has various networking modes,flexible nodes,low energy consumption and high nodes capacity.We also design the hardware(such as sensing nodes,router and coordinator)and software(such as sampling nodes,router and coordinator)of the system,apply the project to the collection and transmission work of mass data in the park,and realize the functions of collection layer and transmission layer in environmental intelligent monitoring;3)Aiming at the demands of function like security,environmental disaster relief and intelligent logistics,smart video is employed based on optical flow field analysis technology in target detection,target identification and behavior anticipation.In order to improve and analyze the behavior-based detection's accuracy degree,a learning machine is designed based on convolutional neural network for deep learning and upgrade systems,which completes the target of smart video functional serves and realizes the internet interconnection of information.ZigBee technology adopted in this paper has well solved the collection and transmission problems of mass wireless sensor data of smart park.In addition,the behavior detection and identification functions of smart video technology are utilized for multiple services.The information platform based on these two technologies well satisfiesthe actual demands of smart park.
