Household NAS Application System Based On Intelligent Router

With the rapid development of cloud computing and Internet of Things technology,the amount of data brought by massive terminal devices has increased significantly.Because of the limited storage capacity of user terminals,most users choose to store data on public or partially private clouds.But public cloud data is managed by third-party storage,data security is not guaranteed,and storage costs are high.The existing private cloud storage products,such as household NAS devices,although have multi-disk RAID system,higher-end configuration and security settings,they are large in power consumption,high price,complex operation,and difficult to expand,which cannot be widely used in the home.In order to solve above problems,it is of great practical significance to build a lightweight,secure,file storage and management are convenient,low storage cost,and flexible private cloud storage system.Based on the hardware and software environment of intelligent router,this thesis uses the extended USB interface provided by intelligent router to mount the U disk as a file storage device,and realizes the development of lightweight household NAS application system.First of all,based on the lightweight operating system tailored and optimized by Linux on the router,the Web server is designed with the Egg framework,and the client is developed with uni-app to achieve multi-terminal publishing.Secondly,My SQL database and Redis cache database are used in data storage,and cache database is used to improve the reading performance of the server,the mixed encryption algorithm of AES and RSA is used to encrypt the stored data,improving data storage security.Finally,in order to meet the flexibility of the device,UPn P and DDNS functions are provided,which can satisfy users' remote storage management of files in U disk.The data storage rate can reach 5000KB/S.The NAS is applied to the intelligent router and integrated into family private cloud storage,which reduces the redundancy of family equipment and reduces the cost and energy consumption of multiple devices.The router operating system used for system development is based on Linux,which has no limitation on router manufacturers,strong portability and easy deployment.The test results show that the developed NAS application system has the advantages of adapting to multi-terminal,convenient file storage and management,flexible expansion,and strong security.Moreover,the Intelligent router mounting U disk solution has low cost,simple operation,can efficiently achieve multimedia file sharing,and can also use the client to achieve multiple expansion functions,which has broad application prospect.
