Designand Implementation Of Security System Based On Technology Of The RFID

The internet of things is seen as the third wave of the information industry following the computer,Internet and mobile communication networks.Because of its broad industry application prospects,governments pay more and more attention to it.The Internet of things is usually divided into three levels by the academia——perception layer,network layer,application layer.In this paper,to realize equipment security system is mainly on the basis of the design of perception layer and application layer.And the transport layer is built by the traditional communication network.The system includes three subsystems:a radio frequency identification system(RFID),the main controller and a data processing platform.In the perception layer,the perceptive device real-timely collects information of device using RFID technology,checks legitimacy of data format and integrity of data and processes data preliminary in logical.The RFID system includes electronic tags and readers,which using CSMA/CD protocol to communicate between them.I simulate CSMA/CD anti-collision algorithm in a specific application environment and finally program the algorithm.The core of the hardware circuit of the electronic tag and reader is CC1110 chip.In the network layer,the system uses traditional communication network to transmit data to the main controller.The main controller does further processing for upload data of the reader and then upload the data to the data processing platform,providing data basis for future application analysis.On the one hand the role of the main controller is gathering the information readers uploading.On the other hand it is used to shield data inconsistencies of readers.In the application layer,the system analyzes vast amounts of data by use of spark real-time streaming computing and the data analysis are stored in the database.Presenting data is in the form of B/S so that the user can easily view device information and does not have to been in the local.The Data processing platform consists of the Spark,MongoDB and Tomcat.Spark is used to do real-time statistics for the label,MongoDB is used to store the information of labels and Tomcat is web middleware used to process user requests and deliver the information back to the user browser.The platform of the internet of things built according to this article has the characteristics of stable performance,real-time high and low false alarm rate and so on,having been shown good practicality.Although the system is designed for security applications scene,it can also be applied to other areas,such as environmental monitoring,crop monitoring by corresponding improvement.
