Description
Technical field
The utility model relates to a kind of electronic price label, and is especially a kind of by radio-frequency (RF) identification and show the electronic price label with LCD display of product information, belongs to wireless telecommunications recognition technology field.
Background technology
Radio-frequency (RF) identification is Radio Frequency ID (Radio Frequency Identification) technology, claim electronic price label, radio frequency identification again, it is a kind of communication technology, utilize radiofrequency signal to realize that by space coupling (alternating magnetic field or electromagnetic field) contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose, this kind technology can be discerned specific objective and read and write related data by radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.
Radio-frequency recognition system is made up of electronic price label (radio-frequency (RF) tag) and reader usually, has the electronic data of certain format in the electronic price label, and is normal with this sign information as article to be identified.In the application with electronic price label attached on the article to be identified, as the electronic marker of article to be identified.Reader and electronic price label can be by the communication protocol transinformations of agreement, and this communication is under contactless mode, utilize the space coupling of alternating magnetic field or electromagnetic field and radiofrequency signal modulation and demodulation technology to realize.
Electronic price label is made up of label antenna (or coil) and label chip usually, and label chip promptly is equivalent to one and has the monolithic system (SoC) that radio transmission-receiving function adds store function again.In the practical application, electronic price label is except having electrical parameters such as data-storing amount, message transmission rate, frequency of operation, many tag readable degrees feature, also according to its inside whether needs add packed battery and battery powered effect and electronic price label be divided into three types of passive label (passive), half passive label (semi-passive) and active labels (active), typical situation is, on low frequency 125kHz, 13.56MHz frequency, generally all adopt passive label, operating distance has the system to 1.5m individually about 10～30cm.At the high frequency uhf band, the operating distance of passive label can reach 3～10m, and more the system of high band generally all adopts active label.
The principle of work of electronic price label is: after label enters magnetic field, if receive the special radiofrequency signal that reader sends, just can rely on the energy that induction current obtained to send out product information that is stored in the chip or the signal that initiatively sends a certain frequency.The Radio Frequency ID chip can be read-only, also read/write mode, and according to the application demand decision, the passive type marking arrangement adopts EEPROM (eeprom), is convenient to use the specific electron treatment facility toward top write data.
EEPROM (Electrically Erasable Programmable Read-Only Memory), eeprom is the storage chip that data are not lost after a kind of power down.EEPROM can on computers or wipe existing information on the specialized equipment, reprogramming generally is used in plug and play.But EEPROM is the ROM (read-only memory) (ROM) of user's change, its can by be higher than common voltage be used for wipe and reprogrammed, EEPROM does not need to take out from computing machine and can revise, in an EEPROM, when computing machine reprogrammed continually when in use.
Traditional price tag is a papery, the need staff is printed or is write, labels, need a large amount of manpower and materials, consume ample resources and time, the change of price each time all needs to make again label, neither environmental protection is also uneconomical, and is not easy to management, and is all the more so for big-and-middle-sized supermarket, market.
