Embodiment
Below in conjunction with drawings and Examples, the application is described in further detail.Be understandable that, specific embodiment described herein is only for explaining related invention, but not the restriction to this invention.It also should be noted that, for convenience of description, in accompanying drawing, illustrate only the part relevant to Invention.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the application in detail in conjunction with the embodiments.
In the following description, a large amount of detail is by the complete description setting forth to provide to embodiments of the invention.But, it should be appreciated by those skilled in the art that the embodiment of the application is not when having these details, also can be implemented.
The object supervisory system of the application adopts RFID technique, can be applied between various object.RFID (Radio Frequency Identification) refers to radio-frequency (RF) identification, also known as radio frequency identification, it is a kind of communication technology, read and write related data by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.Rfid system may be used for control, detection and tracking object.This system can also be connected with computer system to complete more complicated calculating and analysis by various connected mode.
Rfid system generally at least comprises two kinds of basic devices: rfid interrogator and RFID label tag.Can, by the corresponding multiple label of a read write line, also can be the corresponding multiple label of multiple read write line.RFID label tag can be further divided into active label and passive label.Wherein, active label, also known as active tag, itself has internal electric source supply, in order to supply power supply needed for internal integrated circuit IC chip to produce external signal.In general, active tag has the larger memory capacity of longer reading Distance geometry and can be used for storing some appended messages of sending of reader.Passive label, also known as passive label, does not have internal power supply.The internal integrated circuit of passive label is driven by the electromagnetic wave received, and these electromagnetic waves are sent by RFID reader.When passive label receives the signal of sufficient intensity, data can be sent to reader.These data can comprise mark No. ID (whole world uniquely indicates ID), can also comprise the data be stored in advance in tag memory reservoir (such as, electrically erasable read-only memory EEPROM).
Rfid interrogator can associate with equipment with various active object.The RFID label tag scope of application is wider, can associate with various object, because RFID label tag can be passive, therefore any shape and size can be made into, such as can make paster is attached to Anywhere, as the surface of belt, button, key etc., human body can also be attached to or animal body surface prevents from going astray from the group.Describe object and for simplicity for example, in ensuing discussion, describe the exemplary embodiment of the application in conjunction with rfid interrogator and passive RFID tags.
Please refer to Fig. 1, it illustrates the example system block diagram 1000 of the object supervisory system according to the embodiment of the present application.
