Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

The utility model provides an electronic price tag base station which comprises a controller, a power supply module and an NFC communication module, wherein the NFC communication module comprises an NFC chip and N NFC antennas, N is an integer not smaller than 1, the power supply module is electrically connected with the controller to provide electric energy, one end of the NFC chip is electrically connected with the controller, and the other end of the NFC chip is electrically connected with the NFC antennas.

The electronic price tag base station of the embodiment does not need to be embedded with a Zigbee communication module, but can realize near field communication with the electronic price tag by setting an NFC communication module, where near field communication is to exchange data under the condition that NFC antennas are close to each other. When a user needs to update information of the electronic price tag, the electronic price tag is directly close to the NFC antenna of the electronic price tag base station, and the electronic price tag base station can perform near field communication with the electronic price tag through the NFC antenna to send commodity information to the electronic price tag. The electronic price tag base station has the advantages of being simple to operate and low in cost, and the electronic price tag base station can be directly delivered to users for use without professional staff for constructing and maintaining a network.

The number of the NFC antennas can be flexibly adjusted according to the requirement, and the more the number of the NFC antennas is, the more the number of the electronic price tags which can be updated at one time is.

The NFC chip may be an NFC chip that each NFC antenna corresponds to one data processing device, or may share one data processing device with all NFC antennas.

Further, N is an integer not less than 2, and N NFC antennas are distributed.

Further, the N NFC antennas are coils, and in order to avoid mutual interference between the two NFC antennas, the distance between geometric center points of any two NFC antennas is greater than 18mm.

Further, the distance between the geometric center points of any two coils is 28mm to 48mm. At this time, the interference between the NFC antennas is low enough, and the volume of the electronic price tag base station is not too large, so that the portability of the electronic price tag base station is reduced.

Further, the intelligent control device further comprises a buzzer, and the buzzer is electrically connected with the controller. The buzzer can carry out voice prompt on the on-off state, the NFC transmission state and the like.

When the batch information of the N electronic price tags is updated, communication between partial NFC antennas and the electronic price tags is likely to be failed, the first state indicating module can display the communication state of each NFC antenna, and a user can determine the updating state of each electronic price tag by observing the first state indicating module.
