Abstract

Methods, systems and computer devices are provided for adjusting a frame-listening cycle. The method includes: configuring, by a server, a fixed frame-listening cycle of an electronic shelf label according to a time period; and sending, by the server, a second frame-listening cycle modification command through a base station when the server is to issue the fast response service during the low power consumption time period, so that the electronic shelf label modifies the current frame-listening cycle to a fast frame-listening cycle according to the second frame-listening cycle modification command. According to the present disclosure, the electronic shelf label can not only respond to the fast response service in real time, but also keep the low power consumption of a long frame-listening cycle, thereby simultaneously satisfying the requirements of high real-time performance and low power consumption of the electronic shelf label.

First claim

What is claimed is:

1. A shelf label system, comprising:

send a first frame-listening cycle modification command through the base station before the fast response time period or the low power consumption time period of the fixed frame-listening cycle, so that the electronic shelf label modifies a current frame-listening cycle according to the first frame-listening cycle modification command; and
send, in response to issuing the fast response service during the low power consumption time period, a second frame-listening cycle modification command through the base station, so that the electronic shelf label modifies the current frame-listening cycle to the fast frame-listening cycle according to the second frame-listening cycle modification command.

2. The shelf label system according to claim 1 , wherein the server is further configured to:
predict an issuance time period of each service to obtain a time period matching with a service type of each service, wherein the service type comprises the fast response service and the non-fast response service.

3. The shelf label system according to claim 1 , wherein the server is further configured to:
send a broadcast message comprising the current frame-listening cycle to the base station according to a preset broadcast cycle, so that the base station broadcasts the broadcast message to the electronic shelf label, and the electronic shelf label modifies the frame-listening cycle of the current time period according to the current frame-listening cycle in the broadcast message.

4. The shelf label system according to claim 1 , wherein the electronic shelf label modifies the frame-listening cycle of the current time period to the fast frame-listening cycle in response to receiving an external trigger signal.

5. The shelf label system according to claim 4 , wherein the electronic shelf label comprises a touch sensor and a main controller connected to the touch sensor;
wherein the touch sensor sends a frame-listening cycle modification signal in response to acquiring a touch signal;
wherein the main controller modifies the frame-listening cycle of the current time period to the fast frame-listening cycle according to the frame-listening cycle modification signal; and
wherein the main controller sends a heartbeat signal comprising the current frame-listening cycle to the base station, so that the base station sends the current frame-listening cycle of the electronic shelf label to the server.

6. The shelf label system according to claim 4 , wherein the electronic shelf label comprises a key, a key detection circuit, and a main controller connected to the key detection circuit;
wherein the key detection circuit sends a frame-listening cycle modification signal in response to acquiring a key trigger signal;

wherein the main controller sends a heartbeat signal comprising the current frame-listening cycle to the base station, so that the base station sends the current frame-listening cycle of the electronic shelf label to the server.

7. The shelf label system according to claim 4 , wherein the electronic shelf label comprises an infrared sensor, a near-field communication (NFC) acquisition circuit, and a main controller connected to the infrared sensor and the NFC acquisition circuit;
wherein the infrared sensor sends a frame-listening cycle modification signal in response to acquiring a human body approaching signal or in response to determining that the NFC acquisition circuit acquires an NFC communication signal;
wherein the main controller modifies the frame-listening cycle of the current time period to the fast frame-listening cycle according to the frame-listening cycle modification signal; and
wherein the main controller sends a heartbeat signal comprising the current frame-listening cycle to the base station, so that the base station sends the current frame-listening cycle of the electronic shelf label to the server.

8. A method for adjusting a frame-listening cycle, comprising:
configuring, by a server in a shelf label system, a fixed frame-listening cycle of an electronic shelf label in the shelf label system according to a time period, wherein the time period comprises a fast response time period for issuing a fast response service and a low power consumption time period for issuing a non-fast response service, and the fixed frame-listening cycle comprises a fast frame-listening cycle during the fast response time period and a low power consumption frame-listening cycle during the low power consumption time period;
sending, by the server, a first frame-listening cycle modification command through a base station in the shelf label system before the fast response time period or the low power consumption time period of the fixed frame-listening cycle, so that the electronic shelf label modifies a current frame-listening cycle according to the first frame-listening cycle modification command; and
sending, by the server and in response to issuing the fast response service during the low power consumption time period, a second frame-listening cycle modification command through the base station, so that the electronic shelf label modifies the current frame-listening cycle to the fast frame-listening cycle according to the second frame-listening cycle modification command.

9. The method according to claim 8 , further comprising:
predicting, by the server, an issuance time period of each service to obtain a time period matching with a service type of each service, wherein the service type comprises the fast response service and the non-fast response service.

10. The method according to claim 8 , further comprising:
sending, by the server, a broadcast message comprising the current frame-listening cycle to the base station according to a preset broadcast cycle, so that the base station broadcasts the broadcast message to the electronic shelf label, and the electronic shelf label modifies the frame-listening cycle of the current time period according to the current frame-listening cycle in the broadcast message.
