Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings.

Along with the rapid development of the internet of things technology, more and more industries apply the internet of things technology to control internet of things equipment. The electronic tag is also called an electronic shelf tag or an electronic price tag, is internet of things equipment for displaying information such as names and prices of goods, has an information receiving and transmitting function, and can be controlled by using the internet of things technology. For example, control the electronic tag to display information, control the electronic tag to perform system upgrade, and the like.

In large commercial establishments, electronic shelves typically include multiple electronic tags that may display information for the same item or for different items. In the scheme of controlling the plurality of electronic tags by using the internet of things technology, the plurality of electronic tags are accessed to a server (for example, an internet of things server) through gateway equipment (for example, an internet of things gateway), and the server controls the plurality of electronic tags through the gateway equipment.

In the related art, a server sequentially controls the plurality of electronic tags through a gateway device. That is, the server controls only one electronic tag at a time, and after the control of one electronic tag is ended, the server controls the next electronic tag. For example, the server wakes up a plurality of electronic tags in turn, and each time the server wakes up one electronic tag, the server sends task data to the electronic tag through the gateway device, so that the electronic tag performs task processing according to the task data, thereby realizing control of the electronic tag. However, the efficiency of controlling a plurality of electronic tags by the server in the related art is low.

The embodiment of the application provides a control method, a device, a system and a storage medium of an electronic tag. Before the server sends a plurality of pieces of task data corresponding to the plurality of electronic tags to the gateway device, the server sends a transaction start instruction to the gateway device so as to instruct the gateway device to start receiving the task data. The gateway device starts to receive and buffer task data sent by the server after receiving the transaction start instruction. After the server sends the plurality of task data to the gateway device, the server sends a transaction end instruction to the gateway device to instruct the gateway device to end receiving the task data. And the gateway equipment finishes receiving the task data sent by the server after receiving the transaction ending instruction, and wakes up a plurality of electronic tags according to the cached plurality of task data. And then, the gateway equipment simultaneously transmits the plurality of pieces of task data to the plurality of electronic tags, so that each electronic tag in the plurality of electronic tags performs task processing according to the task data corresponding to each electronic tag. The gateway equipment simultaneously controls the plurality of electronic tags to perform task processing according to the plurality of pieces of task data corresponding to the plurality of electronic tags, so that the efficiency of controlling the plurality of electronic tags is improved.

The technical scheme of the embodiment of the application is described below. First, an application scenario of the embodiment of the present application is described.

Please refer to fig. 1, which illustrates a schematic diagram of an application scenario provided in an embodiment of the present application. The application scene provides a control system of the electronic tag. As shown in fig. 1, the control system includes a gateway apparatus 101, a server 20, and a plurality of electronic tags 301 to 303. The gateway device 101 is connected to the server 20 and the electronic tags 301 to 303, respectively. For example, the gateway device 101 is communicatively connected to the server 20 via a wireless network or a wired network, and the gateway device 101 is communicatively connected to the electronic tags 301 to 303 via a wireless network.

Wherein the server 20 is configured to control the electronic tags 301 to 303 through the gateway device 101. For example, the server 20 transmits task data to the electronic tags 301 to 303 through the gateway apparatus 101 to control the electronic tags 301 to 303 to perform task processing. In the embodiment of the present application, before the server 20 sends the task data corresponding to the electronic tags 301 to 303 to the gateway device 101, the server 20 sends a transaction start instruction to the gateway device 101 to instruct the gateway device 101 to start receiving the task data, and after the gateway device 101 receives the transaction start instruction, the server 20 starts to receive the task data sent by the server 20, and caches the task data sent by the server 20. After the server 20 transmits the task data corresponding to the electronic tags 301 to 303 to the gateway apparatus 101, the server 20 transmits a transaction end instruction to instruct the gateway apparatus 101 to end receiving the task data. After receiving the transaction end instruction, gateway device 101 ends receiving task data, and wakes up electronic tags 301 to 303 according to the cached pieces of task data corresponding to electronic tags 301 to 303. Then, the gateway device 101 simultaneously transmits the plurality of pieces of task data to the electronic tags 301 to 303 (for example, the gateway device 101 transmits the task data corresponding to each of the electronic tags 301 to 303 to each of the electronic tags, and the gateway device 101 simultaneously transmits the task data to the electronic tags 301 to 303), so that each of the electronic tags 301 to 303 performs task processing according to the task data corresponding to each of the electronic tags.

The application scenario shown in fig. 1 is illustrated by taking a gateway device as an example of the control system of the electronic tag. In some embodiments, the control system includes a plurality of gateway devices, and the server controls the plurality of electronic tags through all or part of the plurality of gateway devices.

The control system of the electronic tag provided by the application scene comprises gateway equipment 101-102, a server 20 and a plurality of electronic tags 301-306. Gateway device 101 is connected to server 20 and electronic tags 301 to 303, and gateway device 102 is connected to server 20 and electronic tags 304 to 306. For example, the gateway devices 101 to 102 are communicatively connected to the server 20 via a wireless network or a wired network, the gateway device 101 is communicatively connected to the electronic tags 301 to 303 via a wireless network, and the gateway device 102 is communicatively connected to the electronic tags 304 to 306 via a wireless network.

The server 20 is used for controlling the electronic tags 301 to 303 through the gateway device 101, and the server 20 is used for controlling the electronic tags 304 to 306 through the gateway device 102. Description of the control of the electronic tags 301 to 303 by the server 20 through the gateway device 101 and description of the control of the electronic tags 304 to 306 by the server 20 through the gateway device 102 refer to the application scenario shown in fig. 1, and will not be described here.

It should be noted that, the electronic tags 301 to 306 are internet of things devices, the gateway devices 101 to 102 are internet of things gateways, and the server 20 may be an internet of things server. The server 20 may be a server, or a server cluster composed of a plurality of servers, or a cloud computing service center. Wireless networks include, but are not limited to, the world wide web, metropolitan area networks, intranets, generation mobile communication networks (2G, 3G, 4G, and 5G), wireless local area networks, or bluetooth networks, among others. Wired networks include, but are not limited to, twisted pair, optical fiber, and the like.

It should be noted that, the application scenarios shown in fig. 1 and fig. 2 are only for example, and are not used for limiting the technical solution of the embodiment of the present application. The number of electronic tags, the number of gateway devices and the number of servers included in the application scenario may be set according to actual situations, which is not limited in the embodiment of the present application.

The above is an introduction to the application scenario of the present application, and the following describes the method embodiment of the present application.

Referring to fig. 3, a flowchart of a control method of an electronic tag according to an embodiment of the present application is shown. The control method may be applied to a control system as shown in fig. 1 or fig. 2. Referring to fig. 3, the method flow includes the following steps S301 to S309.

S301, the server sends a transaction start instruction to the gateway device, wherein the transaction start instruction is used for instructing the gateway device to start receiving task data.

The server sends a transaction start instruction to the gateway device via a communication connection between the server and the gateway device. The gateway device is any gateway device communicatively coupled to the server. The transaction start instruction includes the number of the plurality of electronic tags that the server needs to control this time. The plurality of electronic tags are all electronic tags hung under the gateway equipment. In one example, the server is the server 20 in the control system shown in fig. 1, the gateway device is the gateway device 101 in the control system shown in fig. 1, and the plurality of electronic tags are all or part of the electronic tags 301-303 in the control system shown in fig. 1. In another example, the server is the server 20 in the control system shown in fig. 2, the gateway device is the gateway device 101 in the control system shown in fig. 2, and the plurality of electronic tags are all or part of the electronic tags 301-303 in the control system shown in fig. 2. In yet another example, the server is the server 20 in the control system shown in FIG. 2, the gateway device is the gateway device 102 in the control system shown in FIG. 2, and the plurality of electronic tags are all or part of the electronic tags 304-306 in the control system shown in FIG. 2.

In alternative embodiments, the transaction start instruction may include a command identification code, a transaction execution code, a transaction duration, and the like. The command identification code is used to identify the transaction start instructions to distinguish between the different transaction start instructions. The command identification code may be an Identification (ID) of the command. The transaction execution code is used to identify transactions to distinguish between different transactions. The transaction execution code may be an identification of the transaction. The transaction duration is the maximum duration of the transaction, in particular the maximum duration from the start of the transaction to the end of the transaction. In the embodiment of the present application, after receiving the transaction start instruction, the gateway device starts executing the transaction corresponding to the transaction start instruction (for example, the transaction is referred to as a target transaction), where executing the target transaction by the gateway device specifically includes the gateway device starting to receive and buffer task data sent by the server, and after receiving the transaction start instruction, the gateway device starts a countdown function according to a transaction duration in the transaction start instruction, and if the countdown is finished, the gateway device determines that the task data is buffered, and the gateway device stops buffering the task data sent by the server, and further, reports a buffer exception response to the server. The embodiment of the application sets the transaction starting instruction to comprise the transaction duration, and can avoid the gateway equipment from generating the abnormality caused by occupying the cache space for a long time when the gateway equipment generates the abnormality due to caching a plurality of task data corresponding to the target transaction.

In an alternative embodiment, a server obtains a task list, generates a transaction start instruction according to the server, and sends the transaction start instruction to a gateway device. In one embodiment, a user selects a plurality of electronic tags based on a display interface of a server, and data content corresponding to each of the plurality of electronic tags. The server acquires tag identifications of a plurality of electronic tags, data content corresponding to each electronic tag and data identifications corresponding to each data content. The server generates a task list corresponding to the gateway device according to the tag identifications of the plurality of electronic tags, the data content corresponding to each electronic tag in the plurality of electronic tags and the data identifications corresponding to the data content. Each action in the task list is task data corresponding to one electronic tag, and the task list is shown in table 1 by way of example.

TABLE 1

And the server counts the number of the tag identifications in the task list according to the task list so as to determine the number of the electronic tags. The server determines the transaction duration corresponding to the number of the electronic tags according to the relation between the number of the pre-established electronic tags and the transaction duration. The server randomly generates a transaction execution code and a command identification code. The server generates a transaction start instruction according to the command identification code, the identification of a transaction transmitting end (such as the server described in the embodiment of the application), the number of electronic tags, the transaction name, the transaction duration and the transaction execution code, and transmits the transaction start instruction to the gateway device. For example, the command identification code is "20230713001", the identifier of the transaction transmitting end is "iot", the number of electronic tags is "3", the transaction name is "StartTransaction", the transaction duration is "60s", the transaction execution code is "20230713115500001", wherein "iot" is used for referring to a server, and the transaction starting instruction is as follows:

S302, the server sends a plurality of pieces of task data to the gateway equipment, the plurality of pieces of task data correspond to a plurality of electronic tags, and each piece of task data is used for controlling the corresponding electronic tag to process tasks.

After the server sends the transaction start instruction to the gateway device, the server starts executing the transaction (i.e., the target transaction) corresponding to the transaction start instruction, and specifically, the server sends multiple pieces of task data to the gateway device. For example, the plurality of task data corresponds to the plurality of electronic tags one by one, and the electronic tags corresponding to different task data are different. Each piece of task data in the plurality of pieces of task data is used for controlling the corresponding electronic tag to process tasks.

In an alternative embodiment, the server sequentially sends the plurality of task data to the gateway device, or the server simultaneously sends the plurality of task data to the gateway device. For example, the server packages the plurality of task data and transmits the packaged task data to the gateway device. In one embodiment, the server transmits the plurality of pieces of task data to the gateway device after a preset time period after transmitting the transaction start instruction to the gateway device. For example, after the server sends the transaction start instruction to the gateway device, the server counts down a preset time period, and the server sends the plurality of pieces of task data to the gateway device when the count down is finished. In another embodiment, after receiving the transaction start instruction sent by the server, the gateway device sends a response instruction to the server, and after receiving the response instruction, the server sends the plurality of task data to the gateway device. Wherein the response instruction is for indicating that the gateway device is ready to receive task data. Illustratively, the response instruction includes: command identification code, identification of transaction sender, transaction name and response information. For example, the command identification code is "20230713001", the identification of the transaction transmitting end is "iot", the transaction name is "StartTransaction", and the response information is "ok". The response instruction is as follows:

{

"id":20230713001,

"from":"iot",

"command":"StartTransaction",

"status":"ok"

}

In an alternative embodiment, each piece of task data in the plurality of pieces of task data includes identification information and data content. The identification information includes a tag identification and a data identification. For the server to send each piece of task data to the gateway device: the server transmits identification information of the task data to the gateway device. After receiving the identification information of the task data, the gateway equipment compares the data identification stored in the cache space with the data identification in the identification information. If the cache space of the gateway device does not include the data identifier in the identifier information, the gateway device sends a data acquisition request to the server to acquire the data content of the task data.
