Description
Technical field
The utility model relates to a kind of rfid device, especially relate to a kind of blade server locating device based on the RFID technology, can be widely used in a plurality of fields such as item tracing management, document management, intelligent commodity shelf, article identification, retail trade shelf management, production line automation management.
Background technology
Radio frequency identification (RFID, Radio-Frequency Identification) be a kind of contactless automatic identification technology, it is automatically identified destination object and obtains related data by radiofrequency signal, and identification work need not manual intervention, can work in various rugged surroundings.The RFID technology can be identified high-speed moving object and can identify simultaneously a plurality of labels, and is swift and convenient to operate.
The composition of rfid system is comprised of label, antenna, read write line, data transmission middleware and management system etc. usually.
Label (Tag): be comprised of coupling element and chip, each label has unique electronic code, is attached to and identifies destination object on object.
Reader (Reader): read the equipment of (sometimes can also write) label information, can be designed to hand-held or fixed;
Antenna (Antenna): transmit radiofrequency signal between label and reader.
Data transmission middleware and management system: middleware is that the data that reader collects are processed the position (as database) that sends to the background system appointment according to operation flow; The management system technology realizes friendly system management interface and related data management function according to customer requirement custom-built system management software.
The groundwork flow process of rfid system: reader sends the radiofrequency signal of certain frequency by emitting antenna, produces induction current when radio-frequency card enters the emitting antenna perform region, and radio-frequency card obtains energy and is activated; Radio-frequency card waits information exchange to cross the built-in transmitting antenna of card self coding and sends; System's receiving antenna receives the carrier signal of sending from radio-frequency card, is sent to reader through the antenna adjustments device, and reader carries out the demodulation code to the signal that receives and then delivers to the backstage main system and carry out relevant treatment; Main system judges the legitimacy of this card according to logical operation, make corresponding processing and control for different settings, sends command signal and controls topworks's action.
The standard of radio-frequency card:
At present, can ISO10536, ISO14443, ISO15693 and ISO18000 be arranged for several standards of radio-frequency card.Using maximum is ISO14443 and ISO15693, and these two standards all are comprised of physical characteristics, radio-frequency power and signaling interface, initialization and anticollision and host-host protocol four parts.
According to different modes, radio-frequency card has following several classification:
1) be divided into active card and passive card by power supply mode.Actively refer to have in card battery that power supply is provided, its operating distance is far away, but the life-span is limited, volume is large, cost is high, and is not suitable for working under rugged surroundings; In passive card, without battery, it utilizes the wave beam power supply technique that the radio-frequency (RF) energy that receives is converted into direct supply for blocking interior circuit supply, and the relatively active card of its operating distance is short, but the life-span is long and less demanding to working environment.
2) be divided into low frequency radio frequency card, high-frequency radio frequency card and super high frequency radio frequency card by carrier frequency.The low frequency radio frequency card mainly contains two kinds of 125kHz and 134.2kHz, and high-frequency radio frequency card frequency is mainly 13.56MHz, and the super high frequency radio frequency card is mainly 433MHz, 915MHz, 2.45GHz, 5.8GHz etc.The low frequency card system is mainly used in short distance, uses cheaply, as the access control of majority, campus card, animal supervision, cargo tracking etc.The high frequency card system is used for access control and needs to transmit the application system of mass data; Ultrahigh frequency card system applies is in needs long decipherment distance and the high-speed occasion of identifying, and its antenna beam direction is narrower and price is higher, uses in the systems such as train monitoring, expressway tol lcollection.
3) difference by modulation system can be divided into active and passive type.The active radio frequency card sends data to read write line on one's own initiative with the radio-frequency (RF) energy of self; The passive radio frequency card uses modulation scattering method transmitting data, and it must utilize the carrier wave of read write line to modulate the signal of oneself, and such technology is suitable for use in gate inhibition or traffic application, because read write line can guarantee only to activate the radio-frequency card within certain limit.In the situation that barrier is arranged, with the modulation scattering method, the energy of read write line must be made a return journey and be passed barrier twice.And the signal of the radio-frequency card of active mode emission only passes barrier once, so the radio-frequency card of active mode work is mainly used in the application of barrier, distance farther (can reach 30 meters).
4) can be divided into close coupling by operating distance closes card (operating distance is less than 1 centimetre), nearly coupling card (operating distance is less than 15 centimetres), loose coupling and closes card (approximately 1 meter of operating distance) and block at a distance (operating distance from 1 meter to 10 meters, even farther).
5) be divided into a Card Reader, read-write card and CPU card by chip.
