Design And Implementation Of Digital Information Management System In Witpark Based On Internet Of Things

In response to a series of policies issued by the state for the construction of smart cities,smart city solutions have been put forward to promote urban development,improve residents' living quality and improve management efficiency.Industrial parks are the concrete manifestations of cities.As the epitome of cities,the development of witpark is imperative.At present,the coverage of information in the witpark is not perfect enough.In terms of announcement and feedback,there is a lack of organic combination of information and the witpark,which leads to problems such as difficult management,poor user perception and information asymmetry between users and managers.At the same time,the subsystems of environmental monitoring and intelligent security in the witpark are relatively independent and resources are scattered,so the interconnection of public data is not realized,which leads to the problem of data isolation and the increase of security risks in the witpark.Therefore,it is of great significance to establish a digital information witpark management system that can not only connect the subsystems in the witpark,but also reduce the difficulty of park management.This dissertation aims at the realization of the witpark system of data linkage,management informatization and service concretization.The technology of the Internet of things is applied to the field of the witpark,and the main structure and functional modules of the digital information management system of the witpark based on the Internet of things are designed and realized.The main work and innovations in this dissertation are as follows:1.After studying the development process and current situation of witpark at home and abroad,the specific requirements of digital information management system in witpark are analyzed.At present,the subsystems of witpark are relatively independent and the data resources are scattered.The application architecture based on the Internet of things is constructed to complete the overall perception and data aggregation in the witpark and solve the problem of data island.2.Under the reality of current situation of difficult park management and labor-intensive,service modules for users are designed and implemented.The forum management module provides a platform for users to exchange information,the message board module establishes a feedback channel in the park,and the park announcement module realizes intelligent notification.The establishment of these modules realizes functions such as intelligent management,network communication,and online publishing,which greatly improves the quality of life and work efficiency of users and managers in the witpark.3.A new data transmission strategy is designed to change the disadvantages of the traditional IoT data single device transmission mode.This transmission strategy improves the data processing efficiency of the witpark application platform side and guarantes data security by using message middleware to complete the aggregation of data of similar devices,combines with data encryption.It also makes full use of the features of peaking and asynchronous messaging middleware to improve the concurrency capability of the witpark application platform.4.The real-time alarm and linkage control functions are designed to deal with the hidden security risks caused by the isolated subsystems in the witpark.Firstly,the uploaded real-time device data is compared with the threshold value,and the alarm function is started if the threshold value is exceeded.Secondly,the linkage control is carried out in combination with the preset mode of the equipment,so as to make full use of the data connectivity to improve the security of the witpark.
