First embodiment
The length of the sleep cycle of the electronic price tag directly influences the service life of a battery of the electronic price tag and the subsequent maintenance cost, so that the sleep cycle of the electronic price tag is generally set to be a long cycle in order to reduce the requirement of power consumption of the electronic price tag and prolong the service life of the battery, but the corresponding disadvantage is that the requirement of quickly responding to a task instruction cannot be met; how to reasonably set the sleep cycle of the electronic price tag so that the electronic price tag can quickly respond to a task instruction and reduce the power consumption of the electronic price tag becomes a problem which needs to be solved urgently; to address the above problem, please refer to fig. 3, and fig. 3 is a basic flowchart of an electronic price tag sleep cycle switching method according to this embodiment, where the electronic price tag sleep cycle switching method includes:
s301, when a roll call instruction is received, switching the sleep cycle of the electronic price tag to a short cycle;
it should be understood that where the server is connected to the base station, the base station is connected to a plurality of electronic price tags, and the electronic price tags, the base station and the server form an electronic price tag system. The base station side comprises a gateway, when a server side issues a task to the base station side, the base station side caches the task, and simultaneously the gateway of the base station side continuously sends a broadcast packet in a broadcast channel, wherein the broadcast packet comprises electronic price tags corresponding to the tasks issued by the server side, and roll calling is carried out on each electronic price tag; when an electronic price tag corresponding to a task issued by a server side needs to be executed and receives the broadcast packet, namely a roll call instruction is received, the sleep cycle of the electronic price tag is switched to a short cycle; when other electronic price tags which do not need to execute the tasks sent by the server side receive the broadcast packet, the broadcast packet is not taken care of because the roll call instruction is not received. That is, the electronic price tag receiving the roll call instruction switches the sleep cycle to a short cycle, and other electronic price tags which are not roll called are not switched.
In some embodiments, switching the sleep period of the electronic price tag to a short period further comprises, upon receiving a service request: respectively configuring short-period and long-period sleep time; for example, the sleep duration of the short period is 300ms, the sleep duration of the long period is 15s, and the sleep duration of each period can be determined according to a specific scenario. It should be understood that the sleep period of the electronic price tag can be configured through the interface, thereby realizing the configuration of long period and short period; the sleep cycle of the electronic price tag can be configured by issuing a command configuration by the base station and the like.
S302, when the electronic price tag meets a preset condition, switching the sleep cycle of the electronic price tag to a long cycle.
In some embodiments, the sleep period of the electronic price tag is switched to a long period when the electronic price tag satisfies a preset condition, wherein the preset condition includes: the electronic price tag fails to establish a link with the gateway; when the electronic price tag receives a roll call instruction and switches the sleep period into a short period, the electronic price tag needs to establish a link with a gateway at a base station side in a handshaking mode; when the handshake between the electronic price tag and the gateway fails, judging that the link establishment between the electronic price tag and the gateway fails; it should be understood that the electronic price tag may not be determined to have failed to establish the link with the gateway until the electronic price tag is subjected to multiple handshakes with the gateway, for example, the electronic price tag may not be subjected to ten handshakes with the gateway, and the electronic price tag may not be determined to have failed to establish the link with the gateway. That is, when the electronic price tag satisfies a preset condition, switching the sleep cycle of the electronic price tag to a long cycle includes: when the establishment of the electronic price tag and the gateway fails, judging that the electronic price tag meets a preset condition, and switching the sleep cycle of the electronic price tag to a long cycle.
In some embodiments, the sleep period of the electronic price tag is switched to a long period when the electronic price tag satisfies a preset condition, wherein the preset condition includes: establishing connection with the gateway and receiving a service instruction; completing corresponding services according to the service instruction; when the electronic price tag receives a roll call instruction and switches the sleep period into a short period, the electronic price tag establishes a link with a gateway at a base station side in a handshaking mode; after the electronic price tag is linked with the gateway, receiving a service instruction transmitted by a server side and forwarded by the gateway, wherein the service instruction comprises but is not limited to: the method comprises the following steps that at least one service instruction in an electronic price tag refreshing information service instruction, an OTA upgrading service instruction and the like is carried out, then the electronic price tag finishes a service corresponding to the service instruction, namely, when the electronic price tag meets a preset condition, switching the sleep cycle of the electronic price tag to a long cycle comprises the following steps: when the electronic price tag is linked with the gateway, and after a service instruction is received, and a corresponding task is completed according to the service instruction, the electronic price tag is judged to meet a preset condition, and the sleep period of the electronic price tag is switched to a long period. It should be understood that, in some examples, when a service instruction is received, if the service corresponding to the service instruction is executed for multiple times continuously and fails, the sleep period of the electronic price tag is also switched to a long period.
In some embodiments, establishing a connection with the gateway device, and receiving the service instruction includes: and establishing connection with the gateway through a 2.4G protocol, and receiving a service instruction. After establishing the connection with the gateway, the method comprises the following steps: sending a heartbeat data packet to ensure the stability of connection with the gateway; specifically, in order to ensure the stability of connection with the gateway, the electronic price tag may send a heartbeat data packet to the gateway side, so as to ensure the stability of connection with the gateway.
In some embodiments, the preset conditions include: the electronic price tag is in a short period exceeding a preset time period. That is, when the electronic price tag receives the roll call instruction, after the electronic price tag is switched to the short period, if the electronic price tag exceeds the short period of the preset time period, for example, the electronic price tag is switched to the segment period sleep mode, and is still in the short period state after 50 short period times, or the electronic price tag is switched to the segment period sleep mode, and is still in the short period state after 300s, it is determined that the electronic price tag exceeds the short period of the preset time period, it should be understood that the preset time period can be freely set, and this embodiment is not limited, that is, when the electronic price tag satisfies the preset condition, switching the sleep period of the electronic price tag to the long period includes: and after the sleep period of the electronic price tag is switched to the short period, judging that the electronic price tag is in the short period exceeding a preset time period, judging that the electronic price tag meets a preset condition, and switching the sleep period of the electronic price tag to the long period.
