Description
Technical field
The present invention relates to Internet of Things field, method for reading data under especially a kind of wireless environment.
Background technology
The practice of technology of Internet of things can trace back to the network cola machine for vending of nineteen ninety Xerox the earliest, and along with the extreme enrichment of development and the various hardware of Internet technology, application software, technology of Internet of things have also been obtained great development.Internet of Things is considered the application extension of the Internet, and the essence of Internet of Things sums up and is mainly reflected in three aspects: one is the Internet feature, and namely the thing needing networking must be capable of the internet interconnected；Two is identify and communication feature, namely includes " thing " of Internet of Things in and must possess and automatically identify the function communicated with thing thing；Three is intelligent feature, and namely network system should have the feature of automatization, self-feedback and Based Intelligent Control.
At present, the concrete application of technology of Internet of things is very many, for instance Smart Home technology, by network, each system relationship in family is managed, be uniformly controlled；Such as car networking technology again, is associated the vehicle in a region by network, it is achieved monitoring, scheduling, tracking etc. application.Put forward a lot of future thrust at present, big such as the wisdom earth, smart city, little of wisdom water utilities, wisdom combustion gas etc., it is contemplated that work and the life of people will to be changed greatly with the next generation internet technology that technology of Internet of things is core.
The main idea of technology of Internet of things is exactly that thing thing is connected, information mutual communication.Current mobile communication equipment all has built-in internal memory mostly, such as smart mobile phone, general at least built-in 8G internal memory, to meet system and the needs of prepackage program, but built-in internal memory is relatively costly, for instance the smart mobile phone price of built-in 32G internal memory generally can than the smart mobile phone expensive 30% of built-in 8G internal memory.And present mobile communication equipment, also mostly allow the internal memory of the mode expansion equipment of user's expansion card, for instance, current smart mobile phone, generally all allow largest extension card to reach 32G, to meet the demand of user's storage.
Even now, but for a user, this extension remains expensive and inadequate, such as with regard to 4-8G not etc., additionally substantial amounts of video, voice data also can take sizable internal memory to the space shared by a high-definition movie, along with the operation of system, various garbage files also can get more and more, therefore, for a user, the memory requirements of expanding mobile communication equipment is endless.
From another one angle, on mobile communication equipment, the data of storage also it is frequently necessary to computer terminal, other move equipment and interact, at present and the data interaction of computer terminal mainly by data wire, mobile communication equipment is interacted as the equipment of a similar USB flash disk, but when mobile communication equipment connects computer by data wire time, mobile communication equipment acquiescence can enter charged state, so the battery of mobile communication equipment is had the charging of a short time, often so operation, can reduce the life-span of battery.And the data communication between multiple stage mobile communication equipment, instant communication software can be utilized at present to carry out, but when the file data amount to transmit is relatively larger time, this mode through instant communication software third-party server transfer wastes flow on the one hand, and expend time in.
At present, also there is the appearance of some wireless U-discs, solve this problem to a certain extent, but the capacity of wireless U-disc is also not open-ended, another one is different from the safety of wired connection, under wireless status, the safety of data is difficult to be guaranteed, this makes people store some sensitive data, for instance worried and doubt when the data that individual's photograph or private life are correlated with.
Therefore, the needs of people propose one and can easily realize mobile communication equipment and unrestrictedly expand capacity, can be moved easily again between communication equipment and computer, mobile communication equipment and carry out the apparatus and method that secure data is mutual, the needs increasingly higher on use mobile communication equipment to meet people.
Summary of the invention
The embodiment of the present invention proposes method for reading data under a kind of wireless environment, the wireless signal of mobile terminal to search wireless card reading device；The certification by wireless signal of the certification deciphering module, obtains storing card data list；Storing card data list is deciphered by certification deciphering module, obtains storing card data list information；Read storing card data.
Further, described wireless card reading device, including memory card slot module, card reading module, interface module, wireless module；Described card reading module respectively with described memory card slot module, described interface module, described wireless module connects, described card reading module obtains power supply from described interface module, detect and read the storing card data inserted in described memory card slot module, and storing card data list is supplied to access user by described wireless module after encryption.
Further, described wireless card reading device also includes authentication ciphering module, and described authentication ciphering module is connected with described card reading module, audits by the user right of wireless module accessing wirelessly.
Further, described user right includes only allowing to read storing card data, it is allowed to reads and is stored in storing card data, it is allowed to reading, be stored in and revise storing card data.
