Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings. The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention.
FIG. 2 is a block diagram of a system for quickly waking up an electronic shelf label and sending a group message according to an embodiment of the present invention, where, as shown in FIG. 2, the system for quickly waking up an electronic shelf label and sending a group message includes an electronic shelf label system console, an electronic shelf label communication control system, an AP, and an electronic shelf label system;
the electronic shelf label system console, the electronic shelf label communication control system, the AP and the electronic shelf label system realize the method for quickly waking up the electronic shelf label and sending the group message as shown in figure 3.
As shown in fig. 3, the method for quickly waking up and sending the group message by the electronic shelf label includes:
step 301: the electronic shelf label system console sends the business message to the electronic shelf label communication control system; the electronic shelf label system comprises a plurality of electronic shelf label clusters, wherein each electronic shelf label cluster comprises a plurality of electronic shelf label groups, and each electronic shelf label group comprises a plurality of electronic shelf labels; the service message comprises a cluster frame and a group frame, wherein the cluster frame comprises a bitmap of a group needing to respond to the service and a group number of a group frame which is transmitted subsequently, and the group frame comprises a bitmap of an electronic shelf label needing to respond, corresponding control information and service data;
step 302: the electronic shelf label communication control system packs the service messages and sends the packed service messages to the AP;
step 303: the AP combines the grouped business messages according to the cluster frames and the grouped frames, and alternately and circularly transmits the cluster frames and the grouped frames in the business messages to an electronic shelf label in an electronic shelf label system in a wake-up period;
step 304: the electronic shelf label determines a wake-up time based on the received cluster frame and the received group frame, and wakes up and executes corresponding service based on the wake-up time.
Specifically, the system for quickly waking up and sending group messages by the electronic shelf label shown in fig. 2 is an asynchronous system, which is challenging to improve real-time performance. The electronic shelf label is a passive electronic product, so that the requirement on power consumption is extremely high. Most of the time is in a deep sleep state. In order to quickly turn on or page a part of electronic shelf labels according to business needs, the invention provides a method for quickly waking up the electronic shelf labels and sending group messages shown in fig. 3, which aims to shorten response time of a terminal (the electronic shelf labels) and complete response time after an instruction is sent from an electronic shelf label console.
The ESL system (electronic shelf label system) control console sends a service message (such as a flashing light is a service) to the electronic shelf label communication control system, then the communication control system sends the service message to the AP under packing scheduling, and the AP is responsible for merging (the same electronic shelf label service can be merged in the same group) and scheduling and finally sends the service message to the ESL.
Specifically, as shown in fig. 4, the electronic shelf label system is virtually divided into three stages, namely a largest first-stage calling cluster and a second largest first-stage calling group; the smallest unit is that each electronic shelf label. Each cluster may contain up to N groups, each group may contain up to M pieces of electronic shelf labels.
Specifically, the invention constructs communication frames by taking clusters as units, each cluster frame comprises bitmaps of all groups needing to respond to the service (the groups with electronic shelf labels needing to communicate are marked by the bitmaps) and group numbers of subsequently transmitted groups, and the groups comprise bitmaps needing to respond to the price labels and specific service data (the groups have control data and service data).
Specifically, the invention uses broadcasting as the awakening of the cluster, and ensures that all electronic shelf price tags in the cluster can receive own cluster frames when periodically awakening to listen to the frames, and the cluster frames have group bitmaps (the groups with the electronic shelf price tags in the groups are marked by the bitmaps to need to be communicated).
Specifically, the invention wakes up (such as lighting or turning pages) according to the group operation, the control data and the service data exist in the group frame, and the group frame can be controlled to each electronic shelf label in the group through the bitmap.
Specifically, in the invention, an AP (base station) processes the service of the ESL in the same cluster in one ESL wake-up period, combines the cluster frames and the GROUP frames, and then circularly transmits the combined cluster frames and the GROUP numbers of the following GROUP frames are filled in each cluster frame, and a timing chart for transmitting the SET (cluster) and the GROUP (GROUP) is shown in fig. 5 (wherein RX represents a receiving time, and idle represents an idle time). The cluster frames and the group frames are alternately sent, so that the electronic shelf label can be ensured to periodically wake up to receive the cluster frames, the moment (namely the wake-up time) at which the self-contained group frames are sent can be calculated immediately after the cluster frames are received, and the self-contained group frames can be received at the wake-up moment after the self-contained group frames sleep in a countdown manner. Meanwhile, part of control frames and service data frames of the electronic shelf labels are combined into a frame, and the frame contains service related data, so that related services can be executed in time.
In an embodiment of the present invention, the method further includes:
the electronic shelf label is provided with a radio frequency window, wherein the radio frequency window is more than 2 cluster frames and framing;
after the electronic shelf label wakes up, the electronic shelf label receives the service message in a radio frequency window.
Specifically, the ESL wakes up periodically, and each wake up will open a radio frequency window larger than (2 cluster frames+group frames) to receive data; if a cluster frame is received, judging whether to wake up, continue to receive and at what time (wake up time) to receive own framing according to the framing number to be waken up (i.e. bitmap of the group needing to respond to the service) carried by the cluster frame and the framing number sent immediately at present, and waking up to receive own framing at the time point, wherein the framing contains control information and service information, and the ESL responds to the control information and the service information.
A frame structure in which a GROUP (SET) wake-up message alternates with control commands of GROUP (GROUP) flash (with bitmap for each ESL); different group recirculation sending modes are adopted to ensure that the ESL can stably receive two cluster frames every time the ESL wakes up a receiving window, and redundant power consumption is not introduced when no own flashing command exists.
In the embodiment of the present invention, as shown in fig. 6, in step 303, the ap merges the packetized service message according to the cluster frame and the framing, including:
step 601: and the AP judges whether the same group exists according to the bitmap of the group requiring the response service in the cluster frame, if so, judges whether the same service exists according to the bitmap of the electronic shelf label requiring the response in the group frame, corresponding control information and service data, if so, the cluster frames and the group frames which are the same in group and have the same service are combined, and the cluster frames and the group frames in the service message are alternately and circularly transmitted to the electronic shelf label in the electronic shelf label system in a wake-up period.
Specifically, the AP is responsible for merging (the electronic shelf label service in the same group can be merged) and dispatching and finally sending to the ESL. If the electronic shelf label service in the same group is different, the electronic shelf label service in different groups can be different.
In the embodiment of the invention, the cluster frame further comprises a countdown for sending a query frame;
as shown in fig. 7, further includes:
step 701: after the countdown of sending the query frame is finished, the AP sends the query frame to the electronic shelf labels in the group according to the group;
step 702: and after the electronic shelf labels in the group receive the inquiry frame, replying to the ACK, wherein the ACK comprises a processing result of the electronic shelf price label processing service.
Specifically, the sending countdown of the query frame is carried out in the cluster frame, when the AP completes the sending of the cluster frame and the framing of one period and the AP selects the group to send the query frame after the countdown is finished, after the ESL in each group receives the query frame, the sending time of the ACK is calculated according to the setting condition of bitmap (the bitmap is N bytes, the bit of each byte corresponds to the label of the electronic shelf label in the group one by one). The ACK has the result of the business processing of the electronic shelf label.
The service frames and the query frames are sent according to the group, and the transmission of the service data and the transmission of the query frames are carried out by applying the thought of multicast, so that the transmission efficiency is improved.
How does the sending time of the ACK be calculated from the rank of bitmaps?
N bytes correspond to n×8 ESLs (1 byte=8 bits), after the big end (which may be the left end) is aligned, each bit corresponds to an ESL, bit 1 represents that the ESL is selected to execute the service, and 0 represents that the ESL does not need to execute the service.
Examples: for example, 32 bytes correspond to 256 ESLs, the 4 th bit of the first byte corresponds to the 4 th ESL, and if this bit is set to 1, this represents that the 4 th ESL needs to perform this service.
According to the bitmap, it can know which ESL needs to send ACK, and the sending time of each ACK is fixed, so that the sending time of each ESL can be calculated.
In an embodiment of the present invention, as shown in fig. 8, the method further includes:
step 801: and the electronic shelf labels in the group calculate the sending time of the query frame of the group according to the countdown of the sending query frame, and the query frame is received at the sending time.
In the embodiment of the invention, the inquiry frame comprises a starting time stamp of each group of electronic shelf labels for replying to ACK and a bitmap of the electronic shelf labels in each group for replying to ACK;
as shown in fig. 9, further includes:
step 901: the electronic shelf labels in the groups calculate the time of replying to the ACK based on the starting time stamp of replying to the ACK by each group of electronic shelf labels in the inquiry frame and the bitmap of the electronic shelf labels in each group needing to reply to the ACK, and the ACK is sent at the corresponding time.
In an embodiment of the present invention, as shown in fig. 10, the method further includes:
step 1001: and the AP judges whether to carry out service retransmission or not according to the result of the ACK.
In the embodiment of the present invention, as shown in fig. 11, in step 1001, the ap determines whether to perform service retransmission according to the result of ACK, including:
step 1101: and if the result of the ACK shows that the service processing of the electronic shelf label fails, carrying out service retransmission.
In an embodiment of the present invention, as shown in fig. 12, further includes:
step 1201: and the AP records the service retransmission times, and returns the ACK to the electronic shelf label communication control system when the service retransmission times reach the upper limit value.
Specifically, after the inquiry is finished, if the service processing of the electronic shelf label fails, the AP is required to initiate the retransmission of the service to the failed electronic shelf label. And reporting the system until the retry times reach the upper limit, and judging whether the ESL of the service is correctly received.
The flow of the method for the electronic shelf label to quickly wake up and send the group message is specifically described below.

(2) And packaging the service message and sending the service message to the AP.
AP behavior:
(1) Receiving the cluster and the framing sent by ESLW, circularly sending the cluster frame and the framing according to a scheduling timing diagram of FIG. 5, and sending a complete listening frame period;
(2) After the transmission is completed, the transmission inquiry is started according to the group, and the ACK (response) of the ESL in the group is received; judging whether retransmission is carried out according to the result of the ACK, and returning the final result to the ESLW after the retransmission times reach the upper limit;
ESL (electronic shelf label) behavior:
(1) According to the listening frame period configured by ESLW, periodically waking up, and opening a radio frequency receiving window larger than the cluster frame plus the group frame after each waking up;
(2) If the cluster frame is received, analyzing the bitmap of the group to be awakened carried in the cluster frame and the serial number of the group frame to be sent immediately; if the ESL is in the awakened bitmap (the bitmap is N bytes, the position of each bit in the N bytes corresponds to the group number one by one), calculating the receiving time corresponding to the electronic shelf label in the group, opening a radio frequency receiving window at the corresponding time, and receiving a framing;
(3) And after the ESL receives the framing, executing corresponding business operation, simultaneously counting down according to query sending in the cluster frame, calculating the sending moment of the query frame of the self-assembled group, receiving the query frame at the corresponding moment, calculating the moment of replying to the ACK according to the bitmap (the bitmap is N bytes of the ESL in the query frame, the bit of each byte corresponds to the label of the electronic shelf label in the group one by one), and sending the ACK at the corresponding time.
How does the time of reception be calculated?
N bytes correspond to N x 8 groups, after big end alignment, each bit position corresponds to a group, bit 1 represents that the group is selected, and 0 represents that the price tag in the group does not need subsequent communication.
Examples: for example, the 3 bytes correspond to 24 groups, the 4 th bit of the first byte corresponds to the 4 th group, and if this bit is set to 1, it represents that there is an electronic shelf price tag in the 4 th group to perform subsequent data reception.
