Abstract
The invention discloses a radio frequency identification (RFID) communication system which comprises two aspects, of which one is a wireless terminal used by a user, and the other is a signal relay server erected in an identification range, wherein the wireless terminal comprises an input module, an output module, a data processing module and a radio frequency identification module; the radio frequency identification module also comprises a controller, a memory, a radio frequency unit and an antenna; and the relay server comprises an RFID reading head and a server which are responsible for data transmission and control in a communication process of users. When a user A wants to realize wireless communication with a user B, the number of B can be input, then the terminal used by the user A transmits an identification number of the terminal, information to be transmitted and an identification number of a terminal b used by the user B; and after the relay server receives the data, b is identified and then the information transmitted to B by A is transferred out.
Description
Technical field:
The invention belongs to the short-distance wireless communication field, be specifically related to a kind of communication system of utilizing radio frequency recognition principle to carry out radio communication.
Background technology:
Along with the develop rapidly of Internet, from WAN to MAN, arrive LAN, PAN again, these technology are ripe gradually.At present, tool growth potential is wireless network in the disparate networks, and many mechanisms can select to adopt wireless lan (wlan) to expand their existing network, obtains the ability at in-house mobile access network.
How not pass through cable, break away from the restriction on the physical connection, devices interconnect is got up? In order to find the answer of this problem, during the last ten years, people constantly explore, and have formed current dazzling wireless communication protocol and product.Wherein, most popular 3 standards about the short-distance wireless data communication are bluetooth (Bluetooth), 802.11 (Wi-Fi) and lrDA.
Radio frequency identification (English Raido Frequency Identification is called for short RFID) is the emerging communication technology that development in recent years is got up, and it can utilize the space of electromagnetic wave transmission to be coupled transmission of realization information and information Recognition.Because it is contactless, need not optical visible, recognition speed is fast, can discern a plurality of targets simultaneously, the environment dependency degree is low, has obtained in a plurality of fields using widely.
During traditional communication identification user, employing be mode to each user's distributing independent frequency range, the expense that therefore in the construction of equipment and antenna, needs is than higher.Through REID, only need a frequency range just can discern a plurality of targets, therefore possessed very big advantage.
Summary of the invention:
Many in order to solve existing short-distance wireless communication technology Mid Frequency consumption; The deficiency that the antenna construction cost is high; The present invention proposes a kind of radio frequency recognition principle that utilizes and realize method of wireless communication, it utilizes single frequency range, just can realize a plurality of identification of targets and intercommunication mutually; The utilance of the frequency range that improves greatly, and reduced equipment cost.
The present invention is achieved in that it comprises two aspects, the one, and the wireless terminal that the user uses, the 2nd, be set up in the signal relay server in the identification range.Wherein wireless terminal comprises input module, output module, data processing module and radio frequency identification module, and radio frequency identification module comprises controller, memory, radio frequency unit and antenna.Wherein Relay Server comprises RFID read head and server, is responsible for transfer of data and control in user and the telex network process.When user A wants with user B realization radio communication; Can import the number of B; The terminal a of user A use sends the identifier of the terminal b of self identifier, need information transmitted and user B use then; Relay Server recognizes b after receiving these data, then A is gone over to the information transmission that B sends.
Description of drawings:
Fig. 1 is the structural representation of wireless terminal according to the invention;
Fig. 2 is the work sketch map of system according to the invention.
(100) wireless terminal among the figure, (110) input module, (120) output module, (130) data processing module, (140) radio frequency identification module; (141) controller, (142) memory, (143) radio frequency unit, (144) antenna, (200) user; (301) user A, (302) wireless terminal a, (303) user B, (304) wireless terminal b; (400) Relay Server, (410) antenna, (420) RFID reader (read head), (430) server.
Embodiment:
Among Fig. 1; Wireless terminal (100) is made up of input module (110), output module (120), data processing module (130), radio frequency identification module (140) four parts, and wherein radio frequency identification module (140) comprises controller (141), memory (142), radio frequency unit (143), antenna (144) again.User (200) realizes information interaction through input module (110) and output module (120) and wireless terminal (100); Wherein input module (110) can make keyboard, touch-screen etc. through input mode, and wherein output module (120) can be the multiple way of outputs such as sound or display.When user (200) need send information; After input module (110) input; After data processing module (130) is handled, be transferred to controller (141), through radio frequency unit (143) and antenna (144) information and the relevant identification information that user (200) needs to send sent out together at last.Wherein identifying information comprises user both sides' radio frequency identification number, and read head can utilize it to identify each different wireless terminal.
Showed a most simply working condition of wireless communication system among Fig. 2; User A (301) sends through the information that wireless terminal a (302) will include wireless terminal a (302) and wireless terminal b (303) radio frequency identification number; After the antenna (410) of Relay Server (400) receives this information; Be transferred to RFID reader (420) and server (430) is handled, therefrom extract the identifier of wireless terminal b (303), and through this identifier and wireless terminal b (303) realization radio communication; The information of being sent to user B (304) user A (301) sends on the wireless terminal b (303), and user B (304) receives this information and promptly realizes this time radio communication.
More than be to explanation of the present invention and non-limiting, based on the various execution modes of inventive concept, all within protection scope of the present invention.
