Abstract
The utility model provides a 2.4GHz active RFID label capable of displaying. The 2.4GHz active RFID label capable of displaying includes an MCU, a 2.4 GHz radio frequency module, an electronic paper driving module, an electronic paper screen, an acceleration sensor and a battery. The MCU is connected with the electronic paper driving module through a GPIO port. The electronic paper driving module is connected with the electronic paper screen through a driving interface of the electronic driving module. The MCU is connected with the 2.4GHz radio frequency module through an SPI port. The MCU is connected with output signals of the acceleration sensor through an interruption port INT. The battery supplies power for the 2.4GHz radio frequency module, the electronic paper driving module, the electronic paper screen and the acceleration sensor. The 2.4GHz active RFID label capable of displaying obtains label identification data simply and directly without using a reading head. The 2.4GHz active RFID label capable of displaying can be utilized repeatedly conveniently and the packaging of the 2.4GHz active RFID label capable of displaying does not need to changed.
Description
Technical field
The utility model relates to the mobile communication technology field, is specifically related to a kind of displayable 2.4GHz active RFID tag.
Background technology
In the application of 2.4GHz active label, it is to finish by 2.4GHz radio frequency read head that the data of label read, leave the zone of radio frequency read head when tag holder after, the data of label then can't read, after the data of label are modified, original some characteristic characters that are printed on the label just may be not suitable with, and need to change the packing of label this moment, again prints New Characteristics character etc.
Shortcoming: the interior user data of label can't show that the recycling of label is difficulty relatively.
The utility model content
In view of this, be necessary the problem mentioned for background technology to provide a kind of displayable 2.4GHz active RFID tag.
The purpose of this utility model is achieved through the following technical solutions:
A kind of displayable 2.4GHz active RFID tag, it comprises a MCU, one 2.4GHz radio-frequency module, one Electronic Paper driver module, one electronic paper screen, one acceleration induction device and a battery, the MCU that tells of institute connects by the GPIO mouth and is connected with described Electronic Paper driver module, described Electronic Paper driver module drives interface by it and is connected with described electronic paper screen, described MCU is connected with described 2.4GHz radio-frequency module by the SPI mouth, described MCU is connected with the output signal of acceleration induction device by middle fracture INT, and described battery is described 2.4GHz radio-frequency module, the Electronic Paper driver module, electronic paper screen and the power supply of acceleration induction device.
Compared with prior art, the utility model possesses following advantage:
1, obtains the tag identifier data simply, directly, need not read head and participate in;
2, the recycling of label is convenient, need not to change the encapsulation of label.
Description of drawings
Fig. 1 is the modular structure synoptic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment provides a kind of displayable 2.4GHz active RFID tag, it comprises a MCU, one 2.4GHz radio-frequency module, one Electronic Paper driver module, one electronic paper screen, one acceleration induction device and a battery, the MCU that tells of institute connects by the GPIO mouth and is connected with described Electronic Paper driver module, described Electronic Paper driver module drives interface by it and is connected with described electronic paper screen, described MCU is connected with described 2.4GHz radio-frequency module by the SPI mouth, described MCU is connected with the output signal of acceleration induction device by middle fracture INT, and described battery is described 2.4GHz radio-frequency module, the Electronic Paper driver module, electronic paper screen and the power supply of acceleration induction device.
Described MCU is by judging the user in the label can show whether data are modified, if be modified, or look-at-me from the acceleration induction device arranged, and then MCU drives the Electronic Paper driver module, and user data is shown on the electronic paper screen.
