Description
Technical field
The present invention relates to be applied to a plurality of fields that the RFID RF Reader is used, in particular to the recognition methods of thing network sensing layer RFID perception information.
Background technology
Internet of Things is meant through various information sensing equipment; Like devices such as sensor, RF identification (RFID) technology, GPS, infrared inductor, laser scanner, gas sensor and technology; To need to monitor, connect, interactive object or process; Gather the information of various needs such as its, light, heat, electricity, mechanics, chemistry, biology, position; And with the information aggregating of gathering on the internet, realize that by internet platform thing is connected with the people's with thing, thing, finally reach identification, manage and control the purpose of all target objects.
Internet of Things is the tide of information industry for the third time after individual PC computing machine, internet.For the first time, China all is the late comer in the information industry tide for the second time, China stands in same starting line with developed countries such as the U.S., European Union, Japan, Korea S in the Internet of Things epoch.
Proposing " perception China " from Premier Wen Jiabao in 2009 had more than 2 years; It is very hot that the notion of Internet of Things is fried; Ministry of Industry and Information, the Department of Science and Technology, each place government support energetically, classify 7 great strategy industries as in China, and industry is given priority in conduct in " 12 " planning.
The RFID RF Reader is the fundamental of Internet of Things.The wireless radio channel that RFID takies has low frequency, high frequency, very high frequency(VHF), the several different frequency ranges of microwave; RFID comprises active and passive 2 kinds; RFID has read-only type of data and reading and writing data type electronic tag; Read-only type reader, reading out type read write line, each read write line can read the perception information of a plurality of RFID.The Data Transport Protocol of RFID in each frequency range different standards arranged.In application, normally a kind of closed-loop system of the RFID application item of every kind of fixed protocol.
Internet of Things be utilize that ripe Internet technology and wired and wireless aware device mature technology realize information between people and thing, thing and the thing interconnect intelligent management and control.
There has been the history that goes up a century the internet that begins till now from the invention wireless telegraph; The transmission of data all is to accomplish through the mode that defines a kind of host-host protocol, develops into the automatic resolution data information of computer from the method for initial artificial resolution data information.The basis of Internet of Things is perceptrons such as RFID, and every kind of perceptron all has different Data Transport Protocols, parses the information of every kind of perception according to host-host protocol.
If can not be to the unified identification of perception and control information, each Internet of Things application system can only be a kind of application of closed loop, forms information island, can't realize interconnecting of information.The unified identification of perception information has become the bottleneck problem of bitter networking development.
Come the recognition methods of resolution data information according to for many years constant transmissions agreement of development, two kinds of solutions are arranged theoretically.
Scheme one is the data message of resolving the number of different types sensor with software simultaneously, can realize the unified identification of sensors of various types.But in practical application; Every kind of perceptron all wants the making software module to carry out data parsing; An Internet of Things application item possibly comprise a variety of awareness apparatus; Resolve the perception information of every kind of agreement and control with software, the complexity of software computing causes the software development cost higher, is difficult to popularize.
Scheme two is to strengthen the standard construction of awareness apparatus; Let more sensing control equipment adopt consistent standard; Form the Data Transport Protocol of formulating a kind of unified standard in the world wide at last; Each awareness apparatus manufacturer makes awareness apparatus by the unified standard agreement, and progressively realizes replacing original sensor with novel sensor the final full identification that realizes all awareness apparatus.But existing awareness apparatus kind is a lot, and prior standard is a lot, and the content of host-host protocol is different with complexity, realize the host-host protocol of world wide unified standard, is impossible accomplish at short notice.
In realizing process of the present invention; The inventor finds that the inputoutput data of read write line of the RFID of different frequency range, different agreement all will communicate with computer; Be unified into the accessible data mode of controlling computer; Through storing RFID perception and control data into the controlling computer database, employing data comparison technology just can realize the technique effect to the full identification of the RFID perception information of different frequency range, communication protocol.
Summary of the invention
The invention provides the recognition methods of a kind of RFID of Internet-of-things perception information, can solve the technical matters of the unified identification of RFID perceptron perception information of multiple different frequency range, differing transmission protocols in the correlation technique.
According to an aspect of the present invention, the recognition methods of a kind of RFID of Internet-of-things perception information is provided, has comprised: the RFID RF Reader is used to send perception information; Rfid interrogator (201) is used to read and write the RFID data; Controlling computer (301) is used to store the RFID inputoutput data, and data contrast identification RFID perception data sends control data; Internet of Things management platform (401) through a plurality of controlling computer of Internet connection, realizes identification, control, information processing to different agreement RFID perception information
In embodiments of the present invention; The perception data that various RFID send changes into the discernible data of computer through corresponding read write line; Every perception data is compared with the perception data that stores storage unit in the controlling computer database in advance into; Find out consistent data, thereby realized full identification different RFID perception datas.Controlling computer is changed a kind of unified transmission protocol data with the perception data of identification and is transferred to Internet of Things management platform database; Parse corresponding data; Obtain the perception information of definition; Thereby realized identification, and the technique effect that makes the transmission data have greater security to different RF ID perception information.The Internet of Things management platform is given controlling computer through a kind of unified host-host protocol transmission steering order in addition; Controlling computer parses corresponding storage control data; Send control data and write the technique effect that realization writes the unified information of controlling the RFID RF Reader to the information of rfid interrogator completion the RFID RF Reader.
