Description
Technical field
The invention belongs to wireless communication technology field, particularly relate to a kind of RFID radio communication meeting national military standard agreement anti-interference
Method.
Background technology
Radio communication is a kind of communication party that the characteristic utilizing electromagnetic wave signal to propagate in free space carries out information exchange
Formula, in recent years in the information communications field, with fastest developing speed, most widely used is exactly wireless communication technology.Radio communication mainly includes
Microwave communication and satellite communication.Microwave is a kind of radio wave, and the distance that it transmits typically only has tens kms.But the frequency of microwave
Band is the widest, and message capacity is the biggest.Microwave communication to build a microwave relay station every tens kms.Development along with society
And progress, the application of communication technology and become people's life, the pith of working and learning, radio communication with its low cost,
Favorable expandability, the advantage such as easy to use have been deep into the various aspects of people's live and work, including mobile phone used in everyday, nothing
Line phones etc., wherein 3G, WLAN, UWB, bluetooth, broadband satellite system, DTV are all that 21 century is the most popular
The application of wireless communication technology.RF identification (Radio Frequency IDentification, RFID) is a kind of radio communication skill
Art, can pass through radio signals identification specific objective and read and write related data, and build between system and specific objective without identifying
Vertical machinery or optical contact.Wireless signal is the electromagnetic field by furnishing radio frequency, data from being attached to article
On label on send out, with automatic identification with follow the trail of these article.The electromagnetic field that some label sends from evaluator when identifying
In can be obtained by energy, be not required to battery；Also label itself is had to have power supply, it is possible to actively to send radio wave and (adjust
Become the electromagnetic field of radio frequency).Label contains the information of Electronic saving, can identify within several meters.With bar code not
With, within radio-frequency (RF) tag need not be in evaluator sight line, it is also possible within embedding tracked object.From concept,
RFID is similar to bar code scan, and for barcode technology, it is encoded bar code to be attached to object and uses special
Scanning read write line utilize optical signal by information by bar shaped magnetic be sent to scan read write line；RFID then uses special RFID to read
Write the RFID label tag of device and special be attached to object, utilize frequency signal that by RFID label tag, information is sent to RFID
Read write line.The most important advantage of radio-frequency recognition system is contactless identification, and it can penetrate snow, mist, ice, coating, dust and dirt and bar
The adverse circumstances label reading that shape code cannot use, and reading speed is exceedingly fast, in most cases less than 100 milliseconds.Active
The literary sketch ability of formula radio-frequency recognition system is also important advantage.Can be used for the interactive service such as flow tracking and maintenance tracking.
RFID is one and is easily manipulated, simple and practical and be particularly suitable for the motility application technology of Automated condtrol.RF identification system
System mainly has the following aspects system advantage: read convenient and swift；Recognition speed is fast；Data capacity is big；Service life is long,
Applied range；Label data can dynamically be changed；Preferably safety.Air interface communication protocol specification read write line and electronics mark
The information interaction of label, it is therefore an objective to for the interconnecting property between different manufacturers production equipment.ISO/IEC formulates five kinds of frequency ranges
Air interface protocol, this thought fully demonstrates the relative property that standard is unified, and a standard is to being quite widely applied system
Joint demand, but the demand of not all application system, one group of standard can meet larger range of application demand.ISO/IEC
18000-6 information technology-RF identification based on single QC reason-be applicable to hyper band 860～960MHz, it is stipulated that read write line
And collision-proof method is added in physical interface, agreement and order between label.It comprises TypeA, TypeB and TypeC tri-
Planting the interface protocol of passive label, communication distance can reach 10m farthest.Wherein TypeC is drafted by EPCglobal,
And get the Green Light in July, 2006, it is in recognition speed, read or write speed, data capacity, anticollision, information security, frequency range
Adaptation ability, the aspect such as anti-interference improve a lot.Within 2006, submitting V4.0 draft, it is for band accessory power supply and sensor
The feature of electronic tag is extended, including label data storage mode and interactive command.The active tag of charged pool can carry
For large range of reading capability and higher communication reliability.For national military standard (GJB) agreement 7377.2-2011 application wide
General property and uniqueness, it is desirable to the equipment of application 7377.2-2011 agreement is suitable for the communication standard of the military, but does not has in prior art
There is the general communication equipment that can be used in national military standard agreement.Existing communication equipment is mainly by main control device and acquisition terminal group
Become, owing in practical operation, main control device is heavy not easily shifted, configure again multiple acquisition terminal, and main control device and collection are eventually
End uses the mode of wired connection, and the shortcoming that this kind of connected mode is brought is the heaviest but also is unfavorable for management, therefore uses wireless company
The mode that connects will be the finer selection of future communications equipment.In the application system of national military standard agreement, wireless-transmission network can not be
The communication network that Wi-Fi, the bluetooth Deng Fei military are suitable for.Based on national military standard (GJB) agreement 7377.2-2011, " main control device "
The anti-interference requirement in communication process of " collecting device " Wireless Telecom Equipment uses frequency hopping to avoid when software design
Interference based on national military standard (GJB) agreement 7377.2-2011 wireless communication module, to realize reliably at PC and PC, PC
Near radio transmission between machine and equipment and equipment and equipment etc..
Summary of the invention
