Abstract

The present disclosure relates to an electronic label, an electronic label system and a data processing method. The electronic label includes an electronic label body and a proximity sensing module. The proximity sensing module is disposed in the electronic label body and configured to detect whether there is a human body within a certain range from the electronic label. In response, the proximity sensing module is configured to generate a corresponding detection signal when a human body is detected. The detection signal is used to obtain a duration of stay of the human body before the electronic label.

First claim

What is claimed is:

1. An electronic label, comprising:
an electronic label body;
a proximity sensing module that is disposed in the electronic label body and is configured to detect a human body within a certain range from the electronic label and generate a corresponding detection signal responsive to detecting the human body, wherein the detection signal is used to obtain a duration of stay of the human body before the electronic label; and
a Microcontroller Unit (MCU), wherein
in response to a presence of the human body being detected, the proximity sensing module outputs a signal of a first level, and the MCU starts timing; and
in response to the human body being detected as outside of the certain range from the electronic label, the proximity sensing module outputs a signal of a second level, and the MCU stops the timing to obtain the detection signal.

2. The electronic label according to claim 1 , wherein the proximity sensing module comprises a pyroelectric infrared sensing unit.

3. The electronic label according to claim 1 , further comprising:
a communication module configured to send the detection signal and corresponding unique identification of the electronic label.

4. The electronic label according to claim 1 , wherein the proximity sensing module is disposed at an intermediate position of the electronic label body and has a preset sensing range.

5. An electronic label system, comprising:
an electronic label that comprises an electronic label body, a proximity sensing module, and a Microcontroller Unit (MCU), wherein
the proximity sensing module is configured to detect a human body within a certain range from the electronic label and generate a corresponding detection signal responsive to detecting the human body;
in response to a presence of the human body being detected, the proximity sensing module outputs a signal of a first level, and the MCU starts timing; and
in response to the human body being detected as outside of the certain range from the electronic label, the proximity sensing module outputs a signal of a second level, and the MCU stops the timing to obtain the detection signal; and

a server end configured to receive the detection signal, and according to the detection signal, obtain a duration of stay of the human body before the electronic label.

6. The electronic label system according to claim 5 , further comprising:
one or more image collection devices configured to collect video images within a predetermined range of the electronic label.

7. The electronic label system according to claim 6 , wherein the server end is further configured to call one of the one or more image collection devices corresponding to the electronic label according to the detection signal, and acquire the video images.

8. The electronic label system according to claim 7 , further comprising:
a first image recognition device configured to recognize the video image to obtain a number of customers within a sensing range of the proximity sensing module.

9. The electronic label system according to claim 6 , wherein the server end is further configured to determine, according to the detection signal, whether a plurality of electronic labels that sense the human body of a customer at a same time period exist, and whether the plurality of electronic labels are adjacent to each other, and determine whether to call ones of the one or more image collection devices corresponding to the plurality of electronic labels according to a determination result.

10. The electronic label system according to claim 9 , further comprising:
a second image recognition device configured to: in response to determining that the plurality of electronic labels that sense the human body at the same time period exist and the plurality of electronic labels are adjacent to each other, pick up video images from the ones of the one or more image collection devices within the time period, recognize the video images within the time period, and determine a product to which attention of the customer is currently paid.

11. A data processing method, comprising:
receiving a detection signal, wherein the detection signal is generated by detecting a human body within a certain range from an electronic label;
obtaining a duration of stay of the human body before the electronic label according to the detection signal;
obtaining a degree of attention for a product corresponding to the electronic label according to the duration of stay;
in response to detecting a presence of the human body, generating a signal of a first level and starting timing; and
in response to detecting the human body as outside of the certain range from the electronic label, generating a signal of a second level and stopping the timing to obtain the detection signal.

12. The data processing method according to claim 11 , further comprising:
obtaining video images corresponding to the electronic label according to the detection signal.

13. The data processing method according to claim 12 , further comprising:
recognizing the video images to obtain a number of customers within a certain range of the electronic label.

14. The data processing method according to claim 12 , further comprising:
determining, according to the detection signal, whether a plurality of electronic labels that sense the human body at a same time period exist and whether the plurality of electronic labels are adjacent to each other;
in response to determining that the plurality of electronic labels that sense the human body at the same time period exist and the plurality of electronic labels are adjacent to each other, obtaining video images corresponding to the plurality of electronic labels within the time period; and
recognizing the video images within the time period, and determining a first product to which attention is currently paid.

15. The data processing method according to claim 14 , wherein recognizing the video images within the time period, and determining the first product to which attention is currently paid comprises:
extracting an action characteristic of the human body; and
identifying the first product to which attention is currently paid based on the action characteristic.

16. The data processing method according to claim 14 , wherein recognizing the video images within the time period, and determining the first product to which attention is currently paid comprises:
identifying an angle between a human eye of the human body and a second product in the video images;
identifying an angle of depression or elevation of the human body in the video images; and
determining whether the second product in the video images is the first product on which attention is currently paid based on the angle between the human eye and the first product and the angle of depression or elevation of the human body.

17. The data processing method according to claim 16 , wherein determining whether the second product in the video images is the first product on which attention is currently paid based on the angle between the human eye and the first product and/or the angle of depression or elevation of the human body comprises:
in response to determining that the human eye and the first product are parallel or the angle of depression or elevation and a deflection angle of the human body are within a first predetermined angle, determining that the first product on which attention is currently paid is placed on a shelf of a rack which is right in front of the human body;
