Description
Technical field
Patent of the present invention relates to the RFID label.
Background technology
Radio-frequency (RF) identification is RFID(Radio Frequency IDentification) technology, claim again radio frequency identification, be a kind of communication technology, can identify specific objective and read and write related data by radio signals, and without setting up machinery between recognition system and specific objective or optics contacts.Current RFID label mainly is divided into passive RFID product, active RFID product, half active RFID product.
The passive RFID production development the earliest, be also develop the most ripe, the product that market is most widely used.Such as, mass transit card, dining room meal card, bank card, hotel access card, China second-generation identity card etc., this is seen everywhere in our daily life, belongs to close contact formula recognition category.The groundwork frequency of its product has low frequency 125KHZ, high frequency 13.56MHZ, ultrahigh frequency 433MHZ, ultrahigh frequency 915MHZ.
The active RFID product, be slowly to grow up recent years, and the characteristic of its far distance automatic identification has determined application space and market potential quality that it is huge.In far distance automatic identification field, as intelligent prison, intelligent hospital, intelligent parking lot, intelligent transportation, the wisdom city, there is major application in the fields such as the wisdom earth and Internet of Things.Active RFID is a dark horse in this field, belongs to far distance automatic recognition category.Product groundwork frequency has ultrahigh frequency 433MHZ, microwave 2.45GHZ and 5.8GMHZ.
Active RFID product and passive RFID product, the characteristic that they are different, determined different applications and different application models, and advantage place is separately also arranged.
Half active RFID product, in conjunction with the advantage of active RFID product and passive RFID product, under the triggering of low frequency 125KHZ frequency, allow microwave 2.45G make the most of the advantage.Half active RFID technology, also can be called low frequency and activate triggering technique, utilizes low frequency closely
accuratelylocation, microwave far-distance identification and uploading data, solve simple active RFID and the passive RFID function realized of having no idea.Briefly, be exactly closely to activate location, identification and uploading data at a distance.
The power supply of current active RFID tag is generally battery, not directly from the civil power power taking as its power supply, due to battery, need to change after being finished, therefore comparatively inconvenient.
And, in some occasion, in asset management, some assets is electric equipments, active RFID tag can be easily in alternating current junction power takings such as plugs as power supply.Thereby can reduce the battery volume or not use battery, and the power lead current situation of electric equipment can be detected, the use information of electric equipment further be detected.
Summary of the invention
For addressing the above problem, it is the active RFID tag of industrial-frequency alternating current that the purpose of patent of the present invention is to provide a kind of civil power that can directly use, and the power lead current situation of electric equipment can be detected, the use information of electric equipment further detected.
The basic comprehension that has below provided the brief overview of patent of the present invention and some aspect of the present invention is provided.This general introduction is not exhaustive overview of the present invention.It not is intended to mean key, decisive key element of the present invention or delineates scope of the present invention.Its sole purpose is to using simplified form to provide some concept of the present invention as the preorder in greater detail to providing after a while.
The technical scheme of patent of the present invention is: the active RFID tag that uses alternating current, a kind of RFID label, comprise antenna, radio transmission module, control module, control module is connected with radio transmission module, radio reception module, also with the AC/DC power module, with control module, is connected.Described RFID label also is connected with AC/DC power module, control module with chargeable battery.Described RFID label also is connected with control module with sensor.Described sensor comprises acceleration transducer.Described sensor comprises optical sensor.Described sensor comprises optical sensor.Described AC/DC power module is connected with AC power.Described RFID label also is connected with control module with the radio reception module.Described antenna is that plate carries antenna or ceramic antenna.Described wireless tender's working frequency is ultrahigh frequency or microwave.
Above-mentioned module can be separately IC, circuit or components and parts, also can a plurality of module collections on an IC.
By such scheme, can even not need battery fully only to supply with civil power with very little chargeable battery, thereby reduce the size of RFID label, and complete the records such as service condition information to electrical equipment by detecting civil power.
The accompanying drawing explanation
Accompanying drawing 1 has provided basic block diagram.
