Abstract

Disclosed are a control method for electronic price tags, an electronic price tag and an electronic price tag system. The control method comprises: receiving at least one first service instruction by a wireless communication module, and receiving at least one second service instruction by a short-distance communication module; and performing, by a fusion processing module, fusion processing on the at least one first service instruction and the at least one second service instruction, which are of a same service type and have an effective duration overlap therebetween, to enable a response module to respond synchronously according to control parameters obtained after fusion processing.

First claim

What is claimed is:

1. An electronic price tag, comprising a wireless communication module, a short-distance communication module, a fusion processing module and a response module; wherein
the wireless communication module is configured to receive at least one first service instruction sent by the server through a base station, and the short-distance communication module is configured to receive at least one second service instruction from a mobile terminal;
the fusion processing module is configured to obtain an effective duration overlap between the at least one first service instruction and the at least one second service instruction according to an issue time of each service instruction and a total effective duration contained in each service instruction, and is further configured to perform fusion processing on the at least one first service instruction and the at least one second service instruction, which are of a same service type and have an effective duration overlap therebetween; and
the response module is configured to respond synchronously according to control parameters obtained after fusion processing.

2. The electronic price tag according to claim 1 , wherein the short-distance communication module comprises a storage unit, wherein the fusion processing module stores first service data in the first service instruction in the storage unit of the short-distance communication module; the wireless communication module comprises a storage unit, wherein the fusion processing module stores second service data in the second service instruction in the storage unit of the wireless communication module.

3. The electronic price tag according to claim 1 , wherein service types of the first service instruction and the second service instruction are both flashing service instructions, each flashing service instruction comprises a flashing color and a total effective duration, and the response module comprises a flashing unit;
the fusion processing module obtains a current effective duration of each flashing service instruction according to an issue time and total effective duration of each flashing service instruction; the fusion processing module determines whether flashing colors of at least two flashing service instructions are the same; and the fusion processing module sends a corresponding flashing control instruction to the flashing unit according to a determining result.

4. The electronic price tag according to claim 3 , wherein when the fusion processing module determines that the flashing colors of the at least two flashing service instructions are the same, a maximum current effective duration of the at least two flashing service instructions is taken as a current flashing duration, and the flashing unit is controlled to flash according to the flashing color and the current flashing duration;
when the fusion processing module determines that the flashing colors of the at least two flashing service instructions are different, a crossed flashing service period and a separate flashing service period are obtained according to the current effective duration of each flashing service instruction; and the flashing unit is controlled to flash alternately according to the flashing colors of crossed service instructions within the crossed flashing service period, and to flash according to the flashing color of a separate service instruction within the separated flashing service period.

5. The electronic price tag according to claim 4 , wherein the at least two flashing service instructions comprise a first flashing service instruction and a second flashing service instruction; the fusion processing module obtains a minimum flashing duration of a first flashing duration and a second flashing duration, and takes the minimum flashing duration as the crossed flashing service period; and the separate flashing service period is obtained by starting from an end time of the crossed flashing service period and ending with an end time of a maximum flashing duration of the first flashing duration and the second flashing duration;
wherein, the first flashing duration is the current effective duration of the first flashing service instruction, and the second flashing duration is the current effective duration of the second flashing service instruction.

6. The electronic price tag according to claim 4 ,
wherein
when the at least two flashing service instructions comprise a first flashing service instruction, a second flashing service instruction and a third flashing service instruction, and the flashing colors of two of the first flashing service instruction, the second flashing service instruction and the third flashing service instruction are the same, the fusion processing module obtains a maximum flashing duration of the two flashing service instructions with the same flashing color as a target flashing duration; a minimum flashing duration of the target flashing duration and a third flashing duration is obtained, and the minimum flashing duration is taken as the crossed flashing service period; the separate flashing service period is obtained by starting from an end time of the crossed flashing service period and ending with an end time of a maximum flashing duration of the target flashing duration and the third flashing duration; wherein, the third flashing duration is the corresponding current effective duration of the flashing service instruction other than the two flashing service instructions with the same flashing color; or
the at least two flashing service instructions comprise the first flashing service instruction, the second flashing service instruction and a third flashing service instruction, the fusion processing module determines that the flashing colors of the first flashing service instruction, the second flashing service instruction and the third flashing service instruction are different, the fusion processing module obtains a minimum flashing duration, a median flashing duration and a maximum flashing duration of a first flashing duration, a second flashing duration and the third flashing duration; the minimum flashing duration is taken as a first crossed period, a difference between the median flashing duration and the minimum flashing duration of the first flashing duration, the second flashing duration and the third flashing duration is taken as a second crossed period, and a difference between the maximum flashing duration of the first flashing duration, the second flashing duration and the third flashing duration and the median flashing duration of the first flashing duration, the second flashing duration and the third flashing duration is taken as the separate flashing service period, wherein the crossed flashing service period comprises the first crossed period and the second crossed period, the second crossed period starts from an end time of the first crossed period, and the separate flashing service period starts from an end time of the second crossed period; or
wherein when the at least two flashing service instructions comprise the first flashing service instruction, the second flashing service instruction and the third flashing service instruction, the flashing colors of the first flashing service instruction, the second flashing service instruction and the third flashing service instruction are different, and flashing durations of two of the first flashing service instruction, the second flashing service instruction and the third flashing service instruction are the same, the fusion processing module takes the flashing duration of the two flashing service instructions with the same flashing duration as a target flashing duration; a minimum flashing duration of the target flashing duration and the third flashing duration is obtained, and the minimum flashing duration is taken as the cros
