Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of communication, in particular to a method and equipment for cloud storage mobile routing equipment supporting multiple access modes.
[ background of the invention ]
With the development of communication technology, mobile communication is developed more and more, and mobile terminals such as mobile phones have functions of more personal entertainment facilities. In some countries, because infrastructure falls behind and fixed networks are not developed, mobile routing devices with mobile communication functions are popular because they can provide network access functions for multiple devices at the same time; users need to store a large amount of photos, music, videos, and the like; on one hand, the price of the flash memory is high, so that many users can buy the mobile phones with low capacity and lower price, and after a period of time, the files of the users have no storage space; on the other hand, storing a file in only one terminal, the risk of loss is high. If the mobile phone and the computer are stolen, lost and damaged, the file cannot be retrieved. How to conveniently expand the capacity of the mobile phone, and the safety of user data can be protected without paying excessive cost, which becomes a problem to be solved urgently; the traditional capacity expansion means, such as otg connecting a U disk to a mobile phone, can only be applied to the mobile phone of the Andorid system, is extremely unattractive and cannot be conveniently shared with other users; the traditional NAS is large in size, not portable, high in purchase cost, inconvenient to access through the Internet, limited in bandwidth and consuming flow; other portable personal memories are not beautiful or even lose portability if a USB interface is used and a USB disk or a mobile hard disk is used as a memory, and further, the USB memory has a high current requirement and cannot be used in a recognizable manner if the current requirement is not met.
At this time, the mobile routing device with the personal cloud storage is born, and the storage can be accessed through various network modes only by inserting the sd card into the mobile routing device. Has the characteristics of small size, attractive appearance, portability and low price; because of portability, in most cases, the wireless local area network can be directly used under a local area network, and has very high transmission rate; meanwhile, files in storage can be conveniently and quickly shared in a local area network or the Internet; the function of authority management is provided, and data is safer; the user can access the storage on various terminals such as a mobile phone, a computer, a panel and a television; the device is internally provided with a DLNA server, and a client can directly play the stored multimedia file on a television supporting DLNA or a client supporting DLNA;
because the mobile routing device generally uses a low CPU frequency and a low memory for portability and a longer service time in a charging cycle, and needs to provide network services for multiple users at the same time, if a conventional design scheme and software scheme are used, the performance becomes a bottleneck, and the functions of providing an Internet network for users and accessing storage at the same time cannot be satisfied.
Cloud storage is now popular, but conventional clouds have the following disadvantages:
(1) some require payment for capacity and service;
(2) the method is limited by the bandwidth of an external network, and if the bandwidth is insufficient or the network connection is not smooth, the uploading and downloading speed is extremely slow;
(3) in the traditional cloud storage, data needs to be uploaded to a server of a cloud provider, a service provider has the authority to perform any operation on files, and the security of user data cannot be guaranteed. The service provider may also terminate the service at any time.
[ summary of the invention ]
The invention aims to solve the following defects of the existing cloud storage: some require payment for capacity and service; the method is limited by the bandwidth of an external network, and if the bandwidth is insufficient or the network connection is not smooth, the uploading and downloading speed is extremely slow; in the traditional cloud storage, data needs to be uploaded to a server of a cloud provider, a service provider has the authority to perform any operation on files, and the security of user data cannot be guaranteed. The service provider can terminate the shortage of service at any time, and provides a novel method and equipment for supporting the cloud storage mobile routing equipment accessed in multiple modes.
The invention is realized by the following technical scheme: a method for supporting cloud storage mobile routing equipment accessed in multiple modes comprises the steps that the mobile routing equipment receives operation requests for files in storage equipment or operation requests for the storage equipment from client equipment; the mobile routing equipment operates a memory or a file in the memory through an SDIO port according to the operation request and outputs an operation result to user equipment; and the mobile routing equipment receives the operation request and uses 3 different service processes for processing according to different request modes.
Further, the operation request for the file in the storage device sent by the client device comprises a file reading list, a file reading list according to the file type, a file searching list according to the file name, a file reading, a file uploading to a directory, a file deleting, a directory deleting, a file renaming, a directory renaming, a file moving or a directory;
the operation request to the storage device sent by the client device comprises a storage state and storage formatting; the memory state comprises the total capacity of the memory, the currently used capacity and the file system format of the memory; the mobile routing equipment supports various mainstream file system formats, if the file system format of the client storage equipment is special, the equipment reminds a client to backup existing files in the storage, and then sends a storage formatting instruction through a UI (user interface) to format the storage into the file system format supported by the equipment.
Further, the 3 different service processes are a file upload request server, a DLNA request server, and an HTTP request server;
the file upload request server: the file uploading request is processed by a file uploading request server; the file uploading request server is only used for receiving file contents and writing the file contents into a storage, after a client device starts to send an uploading request to the uploading request server, the uploading progress inquiry request is sent to the mobile routing device, the mobile routing device sends the file uploading request server to the dynamic API request module, and the dynamic API request module acquires the size of an uploading object to be inquired, which is written into the storage device, and the size of the uploading file from the file uploading request server through an interprocess communication mechanism, so that the specific uploading progress can be obtained;
the DLNA request server: the DLNA client request is processed by the DLNA server;
the HTTP request server: in addition to file upload requests and DLNA requests, these will be handled by the in-device HTTP server.
Further, requests except for the file uploading Request and the DLNA Request are firstly analyzed by a Request analyzer (Request Parser) in the HTTP server, and then the requests are distributed to different modules according to classification for further processing;
the request parser classifies the requests other than the file upload request and the DLNA request into the following two categories:
(1) static file processing request: static html, pictures, CSS and JS contained in the webUI; b. the file reading/downloading request in the storage is delivered to the static processing module for further processing;
(2) the dynamic API processing request, except the static file processing request, delivers other requests to the dynamic API processing module for further processing; the dynamic API request processing module abstracts other storage operations and designs a command type API; the dynamic API request processing module is used for analyzing the operation type, the operation object and the filter parameter by other instructions sent by the client equipment, operating the file appointed in the memory or the memory according to the parameter and returning the operation result.
Further, the mobile routing device receives an operation request of a file in the storage device or an operation request of the storage device from the client device through a WiFi/USB cable/Internet, and before the mobile routing device receives the operation request of the storage device sent by the client device through the WiFi/USB cable/Internet, the mobile routing device further identifies the storage device through the SDIO interface; the mobile router has mounted the storage device in a file system, and the client device may specify an object to be operated by using a Uniform Resource Identifier (URI).
Further, when the mobile routing device receives a dynamic API processing request, if the type of the dynamic API processing request is a cloud storage synchronization request, the dynamic API processing request is distributed to a dynamic API request processing module, the dynamic API processing request processing module analyzes a source address to be synchronized and a target address to be stored, and determines whether a synchronization authority exists, if the synchronization authority does not exist, the client is notified to submit authorization information, after authorization, the device internally initiates a synchronization request, reads file information of the source address, compares the file information with the target address, determines whether a file exists and determines whether the file needs to be written according to file modification time.
Further, the mobile routing device provides a function of manually updating the DLNA index when the DLNA request server is turned on, because a user may replace a new memory card to the device, and when the index is established, the user uploads/deletes/renames/moves a file, the DLNA index is triggered to be updated.
Furthermore, when the webUI and the APP/APK upload large files, the progress query frequency can be dynamically adjusted according to the size of the files in consideration of the equipment performance problem, so that the equipment performance consumption can be reduced; meanwhile, the remaining time for uploading each file can be estimated, and in the next period, the remaining uploading time is calibrated according to the average uploading rate in the previous period; when uploading and downloading files in the Memory, the mobile routing equipment calculates flow control parameters according to the current Internet uploading/downloading rate and the CPU/Memory occupation condition and a specific algorithm, and intelligently adjusts the uploading/downloading rate of the Memory.
A cloud storage mobile routing device comprises an application processor, a cellular modem and a WiFi chip, wherein the application processor is connected with the cellular modem and the WiFi chip.
The device comprises a cellular network, a cellular network interface, an SIM card seat, an SD card seat and a microUSB interface, wherein the SIM card seat is used for placing an SIM card to intervene in the cellular network, the SD card seat is used for placing the SD card to provide a storage space, the microUSB interface can be connected with a charger or the USB interface of the computer, when the microUSB interface is connected with the charger, a device battery can be charged, when the microUSB interface is connected with the USB interface of the computer, the device battery can be charged, and simultaneously, a RNDIS interface can be enumerated on the computer and serves as a network card to provide network service for the computer.
The invention has the beneficial effects that:
(1) different processes are independent from each other, so that the stability can be improved;
(2) each process only processes the request related to the process, so that the processing efficiency can be improved;
(3) reduced coupling, such as DLNA services, e.g. the user does not need to be able to turn off on the UI;
(4) a few operations which need to be matched among processes can be realized through interprocess communication;
(5) the cgi mode is adopted, the difficulty in writing the cgi interface is high, the flexibility is low, and if the cgi interface is changed, the firmware needs to be recompiled to release a new version;
(6) the dynamic languages such as ASP, PHP, Python and the like are adopted, the functions can be satisfied, but the dynamic languages are too heavy and the performance consumption is too large, and the dynamic API request module is lighter;
(7) in the application, an embedded end developer only needs to write each specific function interface according to the specification and register the function interface to a dynamic API request module, and a client device developer only needs to freely combine the interfaces to be called according to the self requirement and write the interfaces to a dynamic request target file; when the client equipment sends a request, a target is a dynamic request target file, and parameters required by an interface are simultaneously transmitted; when the dynamic API analysis module reads the dynamic request target file, the corresponding parameters are transmitted to the appointed interface, the interface executes the appointed operation by combining the parameters, returns the operation result, writes back the operation result to the response of the dynamic request and transmits the response to the client.
