Description
Technical field
The utility model belongs to field of radio frequency identification, and concretely, it provides a kind of electronic tag that has external interface.
Background technology
(claimed electronic label technology again in the REID that grows up in recent years, English Radio Frequency Identification, be abbreviated as RFID), be one and utilize radiofrequency signal to realize that by the space coupling contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose.Because it is contactless, need not optical visible, discern characteristics fast and accurately, all obtained in a lot of fields using widely.
According to the supply mode of radio-frequency (RF) tag work institute energy requirement, radio-frequency recognition system can divide active, passive and half active system.The label of active system uses the battery in the label to power, and the system identification distance is longer, can reach tens meters even rice up to a hundred.Passive RF label does not contain battery, and it is the energy of the energy of electromagnetic field of the read head of coupling emission as oneself, and it is in light weight, volume is little, cost is low, but decipherment distance is shorter, generally is tens centimetres to several meters.Half active system also has battery, but battery only plays the effect of activation system.
Radio-frequency recognition system generally is made up of two parts, i.e. electronic tag and read head.In the practical application of radio-frequency (RF) identification, electronic tag is attached to (surface or inner) on the object that is identified, when have electronic tag be identified the distinguished zone of article by read head the time, read head takes out the agreement identifying information in the electronic tag in contactless mode automatically, thereby realizes automatic identify objects or collect the function of article mark information automatically.
Passive RF label generally comprises antenna, radio-frequency front-end, controller and four parts of storer.Antenna is the structure in order to receive external radio-frequency signal or internal information is sent; Radio-frequency front-end, comprise backscattered modulation circuit, demodulator circuit, power up circuit, power supply stabilization circuit, clock recovery/generation circuit, enabling signal produce circuit, with reference to source generating circuit etc., be mainly used to storage power and start the label internal circuit and keep energy to supply with; Controller comprises AD/DA signal converter, arithmetic processor etc., and it can discern and handle various command and data; Storer has been stored the identifying information of the identity recognition number of radio-frequency (RF) tag at least.
Current REID also has its limitation in application.Radio-frequency (RF) tag generally is an overall package, does not have external interface, and the information in its storer is generally write in advance by read head, so label can't send dynamic information, can't realize the dynamic monitoring of physical quantitys such as temperature, pressure, light intensity.Owing to do not have external interface, can't realize controlled in wireless yet.
Summary of the invention
Can only write the storage data by read head in order to overcome existing electronic tag, can not realize the shortcoming of dynamic monitoring and control, the utility model provides a kind of electronic tag that has external interface, this electronic tag can be realized conventional radio frequency recognition function, can realize dynamic monitoring and control again, the general external interface of this electronic tag makes its application more flexible simultaneously.
The utility model realizes that the used technical scheme of its technical purpose is: in package casing, antenna, radio-frequency front-end, controller, memory order link to each other, add an external interface, electronic tag links to each other with external unit by this external interface, and can send instruction from the external unit reading of data or to external unit by this external interface.This external interface comprises an information transmission unit at least, when external unit can provide power supply to supply with, also can comprise a power supply unit.Wherein information transmission unit links to each other with controller, and power supply unit links to each other with radio-frequency front-end, controller, storer three parts.Controller can be provided with the conducting of external interface or non-conduction state, and when non-conduction, this electronic tag is conventional passive electronic label, and during conducting, this electronic tag can carry out data transmission by external interface.
When this electronic tag was used for dynamic monitoring, its job step was as follows:
1) electronic tag is connected with measuring equipment by external interface, controller is predisposed to nonconducting state with external interface;
2) electronic tag enters the read head identification range, and read head is selected electronic tag, sends data read command;
3) electronic tag receives data read command, and the controller external interface is set to conducting state;
4) controller reads information and processing from the information transmission unit of external interface, will handle the gained data then and go out by radio-frequency front-end, antenna transmission;
5) read head is communicated by letter with electronic tag and is finished, and controller is made as nonconducting state with external interface;
6) read head is passed to server with the data that receive, and the user can recognize the current measured value of measuring equipment by server.
When this electronic tag was used for controlled in wireless, its job step was as follows:
1) electronic tag is linked to each other with working equipment to be controlled by external interface, controller is predisposed to nonconducting state with external interface;
2) electronic tag enters the read head identification range, and read head is selected electronic tag, sends control command;
3) electronic tag receives control command, and the controller external interface is set to conducting state;
4) controller will receive to such an extent that control command is transferred to working equipment by external interface, thereby adjust the duty of working equipment;
5) electronic tag is waited for other orders of read head by the antenna transmission successful information;
6) read head is communicated by letter with electronic tag and is finished, and controller is made as nonconducting state with external interface.
The major advantage that has the electronic tag of external interface described in the utility model is:
1) complete function: when this electronic tag did not link to each other with external unit, it had the basic function of passive electronic label, can realize identification and data transfer under the order of read head; When this electronic tag links to each other with external unit, can realize wireless monitor and control.
2) use flexibly: this electronic tag can link to each other with various device by interface, can link to each other with temperature sensor when for example needing monitor temperature, links to each other with pressure transducer when needing monitoring pressure, can link to each other with equipment such as air-conditioning in the time of need controlling temperature.
3) decipherment distance is far away: when the external unit that connects can be powered, this electronic tag was active duty, makes decipherment distance improve greatly.
