step S310, determining a first wake-up time of a master electronic price tag in an electronic price tag group to be updated, wherein the electronic price tag group to be updated comprises the master electronic price tag and at least one slave electronic price tag;
step S320, determining the current time when the gateway and the main electronic price tag are in communication;
Step S330, determining slave electronic price tag information to be paged in the at least one slave electronic price tag according to the first wake-up time and the current time;
step S340, paging the corresponding slave electronic price tag to be paged according to the slave electronic price tag information to be paged.
Through the embodiment, when the gateway updates the electronic price tag group of the N-th group, the gateway pages the main electronic price tag of the group and establishes communication with the main electronic price tag, after establishing communication with the main electronic price tag, the gateway records the first awakening time of the main electronic price tag, when the gateway finishes the communication after finishing updating the main electronic price tag, the gateway records the current time, at this time, the gateway determines the information of the secondary electronic price tag to be awakened according to the first awakening time and the current time, and pages the secondary electronic price tag corresponding to the information of the secondary electronic price tag. By the method, the gateway purposefully searches the slave electronic price tag to be awakened after the gateway finishes communication with the current electronic price tag, so as to accurately page the electronic price tag to be in the awakening state, further reduce the waiting time before the gateway communicates with a single price tag, and further improve the efficiency of batch updating of price tags.
The above steps will be specifically described with reference to specific embodiments.
In step S310, a first wake time of a master electronic price tag in the set of electronic price tags to be updated is determined.
Specifically, in the electronic price tag system, the electronic price tag updates information on a display screen of the electronic price tag by receiving update information transmitted by the gateway device. Typically, merchants will include a large number of electronic tags in the context of using electronic tags that go through timed dormancy and awakening to receive updated information sent from the gateway device. In this embodiment, these electronic tags are grouped. The electronic price tags can be grouped according to the coverage area of the gateway equipment, the product attributes applied by the electronic price tags can be grouped according to the product attributes, and the electronic price tags can be grouped according to the area where the electronic price tags are located. For example, electronic tags may be divided into 10 groups.
The electronic price tag group to be updated is the electronic price tag group which needs to be updated in the divided multiple electronic price tag groups. Each electronic price tag group comprises a master electronic price tag and a plurality of slave electronic price tags, wherein the master electronic price tag is the first paging electronic price tag when the gateway updates one electronic price tag group. Each electronic price tag group is provided with a group identifier, the electronic price tags in each electronic price tag group are provided with corresponding price tag identifiers, the gateway equipment stores the group identifier of each electronic price tag group and the price tag identifiers corresponding to the electronic price tags in each electronic price tag group in advance, so that the gateway equipment can directionally page specific electronic price tags through the group identifiers and the price tag identifiers.
The electronic price tag defaults to a fixed sleep period, and the electronic price tag wakes up or sleeps according to the control of the fixed sleep period, that is, the electronic price tag has sleep time and wake-up time. In this embodiment, the first wake-up time is a wake-up time when the main electronic price tag receives the paging information of the gateway.
In an alternative embodiment, step S310 may be performed by:
step S3101, paging the main electronic price tag in the electronic price tag group to be updated;
step S3102, determining that the response information of the main electronic price tag is received, and recording the current time point as the first wake-up time point.
Specifically, when the gateway does not page the main electronic price tag, the main electronic price tag wakes up and sleeps periodically, and when the gateway needs to update information of the electronic price tag group to be updated, the gateway only pages the main electronic price tag of the electronic price tag group to be updated. When the main electronic price tag ends the dormancy period and enters the awakening state, the paging information for the main electronic price tag is detected, and the paging information is responded, so that the gateway establishes communication with the main electronic price tag, and meanwhile, the gateway updates the main electronic price tag. Meanwhile, the gateway records that the current time point at the moment is the first wake-up time point.
In step S320, a current time when the gateway ends communication with the master electronic price tag is determined.
Specifically, after the gateway establishes communication with the main electronic price tag, the information in the main electronic price tag is updated, for example, the content on the display screen in the main electronic price tag is updated, so that when the gateway updates the electronic price tag, a period of updating time is required, that is, a time interval exists between the first wake-up time when the gateway establishes communication with the main electronic price tag and the current time after the updating is finished.
In step S330, slave electronic price tag information to be paged in the at least one slave electronic price tag is determined according to the first wake-up time and the current time.
Specifically, the gateway stores electronic price tag information, such as an electronic price tag identifier, of each electronic price tag. In this embodiment, the electronic price tag corresponding to the slave electronic price tag information to be paged is the slave electronic price tag whose wake-up time is closest to the current time. The electronic price tags in the electronic price tag group are sequentially awakened and dormant according to the sequence, and the gateway stores information capable of determining the awakening and dormant sequences of the electronic price tags, namely, the gateway can determine when the slave electronic price tags in the electronic price tag group are in an awakening state and in a dormant state, so that when the gateway and the master electronic price tag are updated, the slave electronic price tag with the awakening time closest to the current time is searched as the slave electronic price tag to be paged according to the current time when the gateway and the master electronic price tag are ended.
In the present embodiment, step S330 may be performed by:
step S3301, determining wake-up time corresponding to each electronic price tag in the at least one slave electronic price tag according to the first wake-up time;
step S3302, determining a wake-up time closest to the current time;
in step S3303, it is determined that the electronic price tag information corresponding to the wake-up time is the slave electronic price tag information to be paged.
Specifically, in step S3301, each electronic tag in the electronic tag group sequentially wakes up and sleeps at fixed time intervals with respect to the main electronic tag. The gateway stores corresponding fixed time interval information and corresponding slave electronic price tags, so that after the gateway obtains the first awakening time of the master electronic price tag, the gateway can calculate the time for sequentially awakening the slave electronic price tags according to the first awakening time.
In this embodiment, a time offset for determining each of the at least one slave electronic price tag with respect to the master electronic price tag is stored in advance. Step S3301 is to determine wake-up time corresponding to each electronic price tag in the at least one slave electronic price tag according to the first wake-up time and the time offset. Specifically, in the electronic price tag group, the master electronic price tag and the slave electronic price tag are also sequentially awakened and dormant according to the time offset, for example, the first slave electronic price tag is offset by 500ms, the second slave electronic price tag is offset by 1000ms, and the third slave electronic price tag is offset by 1500ms, that is, after each slave electronic price tag is awakened by 500ms, the next slave electronic price tag is in an awakened state. Because the gateway adopts the same calculation method as the method for determining the wake-up time of each electronic price tag in the electronic price tag group and stores the identification of each electronic price tag, the gateway can ensure that the time offset calculated by each electronic price tag and the gateway is the same for the specific electronic price tag. That is, the gateway can quickly establish communication with each slave electronic price tag by calculating the wake time of each slave electronic price tag according to the first wake time and the time offset to be the same as the wake time of each slave electronic price tag in the electronic price tag group, and thus, when the gateway pages the slave electronic price tag which is to be in the wake state at a certain moment according to the calculated wake time, since the slave electronic price tag is just in the wake state at the moment, the gateway can quickly establish communication with the slave electronic price tag, and the paging waiting time is reduced.
In step S3302, after the gateway calculates the wake-up time of each slave electronic price tag in the electronic price tag group, the gateway determines the wake-up time closest to the current time by comparison. In this way, the gateway can directly page the slave electronic price tag closest to the current time when paging.
In step S3303, since the tag identifier corresponding to each slave electronic tag is stored in the gateway, the gateway can determine the wake-up time corresponding to each slave electronic tag, and after the gateway determines the wake-up time closest to the current time, the gateway can determine the slave electronic tag identifier corresponding to the wake-up time, and further, determine that the electronic tag information is the slave electronic tag information to be paged.
According to the embodiment, when the gateway updates the electronic price tag group, only the main electronic price tag in the electronic price tag group is firstly paged, after communication is established with the main electronic price tag, the wake-up time of each auxiliary electronic price tag in the electronic price tag group can be calculated according to the first wake-up time of the main electronic price tag, when the gateway and the main electronic price tag finish communication, the closest wake-up time is compared according to the current time when the gateway and the main electronic price tag finish communication, and then the auxiliary electronic price tag information corresponding to the wake-up time is determined, so that the gateway can establish communication with the auxiliary electronic price tag with the minimum waiting time when paging the corresponding auxiliary electronic price tag according to the auxiliary electronic price tag information.
In step S340, the corresponding slave electronic price tag to be paged is paged according to the slave electronic price tag information to be paged.
And after determining the information of the slave electronic price tag to be paged currently according to the first wake-up time and the current time after the communication with the master electronic price tag is finished, the gateway pages the slave electronic price tag and establishes communication so as to update the slave electronic price tag. It should be noted that, when the gateway continues to acquire the current time when the slave electronic price tag finishes communication after finishing updating the slave electronic price tag, and further determines the wake-up time closest to the current time again, through such a cycle, the electronic price tag in the electronic price tag group can be updated with the least waiting time.
FIG. 4 is a flow chart of an embodiment of an electronic price tag management method provided herein. Once triggered by a user, the process in this embodiment automatically operates through the electronic terminal, where each step may be performed sequentially as shown in the flowchart, or may be performed simultaneously according to a plurality of steps in actual situations, which is not limited herein. The electronic price tag management method provided by the application comprises the following steps:
Step S410, a plurality of slave electronic price tags wake up and sleep in sequence according to the wake-up time of the master electronic price tag;
step S420, the slave electronic price tag to be paged receives paging information corresponding to the slave electronic price tag to be paged, wherein the slave electronic price tag to be paged is a slave electronic price tag corresponding to slave electronic price tag information determined by the gateway according to the first wake-up time of the master electronic price tag and the current time when the gateway and the master electronic price tag are in communication end, from the plurality of slave electronic price tags.
Specifically, in step S410, the master electronic price tag synchronizes the wake-up time of the slave electronic price tags in the present group by means of regular broadcasting. In the present embodiment, step S410 may be performed by:
step S4101, dividing a plurality of electronic price tags into electronic price tag groups, wherein the electronic price tag groups comprise main electronic price tags and a plurality of auxiliary electronic price tags, and the main electronic price tags are the first paging electronic price tags when the gateway updates the current electronic price tag groups;
step S4102, the plurality of slave electronic price tags respectively determine wake-up time relative to the master electronic price tag according to the synchronization information of the master electronic price tag;
In step S4103, the plurality of slave electronic price tags sequentially perform sleep and wake-up according to the corresponding wake-up time, respectively.
In step S4101, N electronic tags are grouped into a group, and one master electronic tag in the group is determined, and other electronic tags are called slave electronic tags. In step S4102, the master electronic price tag periodically broadcasts time synchronization information of the group, and other slave electronic price tags synchronize their own local time after receiving the information; at the time of the first grouping, the master electronic price tag is controlled to continuously broadcast a time synchronization message T1 time, for example, t1=1 minute, and the slave electronic price tag can synchronize time information in time within the time period. In the present embodiment, step S4102 may be performed by:
step S41021, receiving synchronization information broadcasted by a master electronic price tag, wherein the synchronization information comprises a time offset of the slave electronic price tag relative to the master electronic price tag;
in step S41022, the slave electronic price tag determines a wake-up time relative to the master electronic price tag according to the corresponding price tag identification and the time offset.
Specifically, the time offset is an offset with respect to the main electronic price tag, for example, the time offset may be an offset with respect to a sleep start time point of the main electronic price tag, and since the sleep time length of each electronic price tag is the same, the offset with respect to the sleep start time point of the main electronic price tag, that is, an offset with respect to a wake time of each slave electronic price tag. In this embodiment, the time offset of each slave electronic price tag with respect to the master electronic price tag is different, but the time intervals of the wake-up times of two adjacent slave electronic price tags are the same, for example, the time intervals of the wake-up times between two adjacent electronic price tags are the same among the four electronic price tags numbered 2, 3, 4, and 5. In step S41022, each electronic price tag in the set of electronic price tags has a corresponding price tag identification, e.g., number 2, number 3, etc. After each electronic price tag receives the synchronization information of the master electronic price tag, determining the corresponding time offset relative to the master electronic price tag according to the time offset and the corresponding number in the synchronization information, for example, the time offset is 500ms, and then the first slave electronic price tag is offset by 500ms and the second slave electronic price tag is offset by 1000ms.
Through the embodiment, the electronic price tags in each electronic price tag group have the corresponding time offset corresponding to the main electronic price tag, so that each electronic price tag can wake up and sleep at one time according to the sequence of time.
In step S420, each slave electronic price tag wakes up and sleeps in turn according to the respective wake-up time, and when the slave electronic price tag is in the wake-up state, if paging information from the gateway is detected, a response is made to establish communication with the gateway.
