Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Fig. 1 is a schematic diagram of an electronic price tag communication system according to an embodiment of the present invention, as shown in fig. 1, the system includes:
a processor, a plurality of wireless access points, and a plurality of sets of electronic price tags, wherein,
each wireless access point corresponds to a plurality of electronic price tag groups, and each electronic price tag group comprises a plurality of electronic price tags;
the processor is configured to: sending update data to a wireless access point corresponding to an electronic price tag group where an electronic price tag needing data update is located, wherein the update data comprises a plurality of update data packets;
the wireless access point is configured to: after receiving the updating data sent by the processor, sending a group awakening message to the electronic price tags needing data updating, wherein the group awakening message comprises a plurality of countdown durations for receiving the updating data of the electronic price tags needing data updating; after the electronic price tags needing data updating wake up according to the countdown duration of each piece of received updating data, simultaneously sending unsent updating data packets corresponding to the electronic price tags of the same electronic price tag group needing data updating until all the updating data packets corresponding to the electronic price tags are sent;
the electronic price tag is used to: periodically waking up, receiving a group wake-up message after waking up, and obtaining a plurality of countdown durations for receiving updated data; and waking up again according to the countdown time length of each received updating data, and receiving the updating data packet which is not received once until all the updating data packets are received completely.
In the embodiment of the invention, the electronic price tag periodically wakes up to receive the group wake-up message, and receives the group wake-up message after waking up; waking up again according to the countdown duration of each received updating data, and receiving the updating data packet which is not received once until all the updating data packets are received completely, so that the power consumption of the electronic price tag at the time of waking up is very small; after the electronic price tag which needs to update data wakes up according to the countdown time length of each received updating data, simultaneously sending unsent update data packets corresponding to the electronic price tags of the same electronic price tag group which need to be subjected to data update until all the update data packets corresponding to the electronic price tags are sent, so that when the wireless access point simultaneously transmits the updating data packet to the electronic price tags which need to update data in the same electronic price tag group, the adjacent number updating data packet transmitted by the wireless access point is transmitted to different electronic price tags, and there is a time interval between update packets of different batches of the same electronic price tag in which the duration of the countdown to receive the update data is long, therefore, enough time for processing the update data packet is provided for the electronic price tags, and the communication efficiency of a plurality of electronic tag groups is improved.
In specific implementation, the processor is responsible for storing the one-to-one corresponding relation between each electronic tag and a certain commodity in the supermarket; and is responsible for managing a plurality of wireless access points distributed in one or more supermarkets, including wireless channel information of the access points, such as working wireless frequency, and initiating working orders; the processor generates the content to be displayed of the corresponding electronic price tag according to the data pushed by the supermarket background ERP database, forms the updating data of the electronic price tag needing data updating, finds the wireless access point corresponding to the electronic price tag group where the electronic price tag is located, sends the updating data to the wireless access point, and finally sends the data to the electronic price tag through the wireless access point.
The electronic price tag is in an un-awake state by default in order to save power consumption, and can receive the group wake-up message after waking up, and the wireless access point sends the group wake-up message to the electronic price tag which needs to perform data update after receiving the update data sent by the processor, so that in order to enable the electronic price tag to receive the group wake-up message, the time length for the wireless access point to send the group wake-up message needs to cover the interval for the electronic price tag to wake up twice to receive the group wake-up message, and the group wake-up message carries the countdown time length for a plurality of electronic price tags which need to perform data update to receive the update data. And after receiving the group wake-up message, the electronic price tag acquires a plurality of countdown durations for receiving the updating data, performs timing countdown on each countdown duration for receiving the updating data, wakes up again according to each countdown duration for receiving the updating data, and starts to receive the updating data.
Because the electronic price tags need low power consumption, the MCU (Microcontroller Unit) used by each price tag is generally weak in computing capability, if the wireless access point communicates with only one electronic price tag at the same time, the MCU with low power consumption is not ready to process the updating data packets, so that the wireless access point can communicate with a plurality of electronic price tags needing data updating at the same time by adopting a group communication mode, the adjacent data packets are for different electronic price tags, and after the electronic price tags needing data updating wake up according to the countdown time length of each updating data receiving, the unsent updating data packets corresponding to the electronic price tags are simultaneously sent to the electronic price tags needing data updating in the same electronic price tag group until all the updating data packets corresponding to the electronic price tags are sent, so that countdown for receiving the updating data exists among a plurality of batches of updating data packets of the same electronic price tag The time interval of the duration is such a time interval that enough time for processing the update data packet is given to the electronic price tags, the communication efficiency of a plurality of electronic tag groups is improved, and the group communication efficiency and the low power consumption problem of each electronic price tag are well considered.
In specific implementation, each electronic price tag group corresponds to one wireless access point, and the processor and the electronic price tags perform update data transmission through the wireless access points, so that the communication condition between the wireless access points of the electronic price tags is very important, and it is required to ensure that each electronic price tag corresponds to an optimal wireless access point.
In one embodiment, the electronic price tag is further for: sending heartbeat data packets to a plurality of wireless access points after periodically waking up;
the wireless access point is further configured to: receiving a heartbeat data packet of the electronic price tag, and obtaining signal intensity data when the heartbeat data packet of the electronic price tag is received; sending signal intensity data corresponding to the heartbeat data packet of the electronic price tag to a processor;

In the above embodiment, after the electronic price tag wakes up periodically, the electronic price tag actively sends heartbeat data packets to the plurality of wireless access points, where the period may be 3 minutes or even longer, a specific process may be that the wireless access points start a heartbeat receiving function on a receiving public wireless channel in a system silent state, the electronic price tag sends heartbeat data packets on the public channel, and the plurality of wireless access points receive the heartbeat data packets to obtain signal strength data when receiving the heartbeat data packets of the electronic price tag; sending signal intensity data corresponding to the heartbeat data packet of the electronic price tag to a processor; the processor receives and determines the optimal wireless access point corresponding to the electronic price tag according to the signal intensity data corresponding to the heartbeat data packets of the electronic price tags sent by the wireless access points, namely, the optimal wireless access point for updating data is determined according to which wireless access point the electronic price tag adopts, and when the optimal wireless access point corresponding to the electronic price tag is inconsistent with the current wireless access point, networking is performed on the electronic price tag according to the optimal wireless access point.

The electronic price tag group number of the electronic price tag is modified into the group number of one of the electronic price tag groups corresponding to the optimal wireless access point, for example, one wireless access point A can correspond to the electronic price tag group 1, the electronic price tag group 2 and the electronic price tag group 3, if one electronic price tag is in the electronic price tag group 4, the optimal wireless access point determined through the process is A, the electronic price tag group number of the electronic price tag can be changed, the logic group number of the electronic price tag is changed into 1, 2 or 3, theoretically, all the electronic price tags with the same logic group number are close in physical positions, and the approximate rate can be communicated by using the same wireless access point.
