Description
Technical field
The present invention relates to materials management technique fields, and in particular to a kind of handling of goods and materials side based on active electronic label
Method.
Background technique
Electronic tag is a kind of contactless automatic identification technology, it is identified target object by RF signal and obtained
Related data, identification work are not necessarily to manual intervention, and RFID technique has waterproof not available for bar code, antimagnetic, high temperature resistant, makes
With the service life it is long, read that distance is big, data can encrypt, storing data capacity is bigger on label, the change of storage information is freely etc. excellent
Point.Coding mode, storage and the read-write mode of electronic tag are different from conventional labels (such as bar code) or manual label, electronic tag
The storage of coding is on the integrated with the storage of read-only or read-write format；Especially read-write mode, electronic tag are to use nothing
Line electron-transport mode is realized.Outstanding be technically characterized by comprising the steps as follows: of RFID electronic label can identify single very specific object,
A type objects can only be identified like that rather than bar code；Multiple objects can be distinguished simultaneously, and bar code can only be one
It reads on one ground；The information content of storage is very big；Using radio frequency, data can be read through exterior material, and bar code must
Information must be read by laser or the infrared surface in material medium.
According to inside tags power supply, whether there is or not RFID label tag is divided into passive type, semi-passive (also referred to as semi-active type), active
Formula three classes.Unlike passive type and semi-passive, active tag itself has the supply of internal electric source I V, to supply
Power supply I V needed for internal IC is to generate external signal.In general, active tag possesses longer reading distance and can hold
Biggish memory size of receiving, which can be used to store reader, transmits some appended messages come.Active and semi-passive label
Difference is；Active tag can be by internal power, on the internal document to reader that actively emits inner label at any time.Actively
Formula label is also known as active label, and built-in battery forms effective behaviour area using own electric power around label, actively detects
Arround whether there is or not the call signals of reader transmitting, and by the data transmission of itself to reader.
In existing handling of goods and materials, much all still carried out using artificial mode, management method and administrative skill are all non-
Often fall behind, and whether be unable to real-time detection goods and materials in library, often a goods and materials cannot find to have lost in time after loss
Lose, cause the goods and materials lost because drop-out time is too long and the problem of can not recover.
