The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below in conjunction with the accompanying drawings.

The management of electronic signage adopts a centralized central cloud method. If the cloud service fails or goes down, it will cause delays in refreshing the electronic signage or loss of data, and the availability of the electronic signage cannot be guaranteed. On the other hand, when the number of electronic signage reaches a certain scale, cloud services will cause problems such as system pressure, computing delay, and full network bandwidth, which will affect the availability of electronic signage.

The embodiment of the present application provides a request processing method using the collaborative management of the central cloud and the edge cloud, so as to solve the above technical problems.

Among them, cloud computing (Cloud Computing) is the increase, use and interaction mode of related services based on the Internet, usually involving the provision of dynamically scalable and often virtualized resources through the Internet. Cloud computing is distributed computing (Distributed Computing), parallel computing (Parallel Computing), utility computing (Utility Computing), network storage (Network Storage Technologies), virtualization (Virtualization), load balancing (Load Balance), hot backup redundancy ( High Available) and other traditional computer and network technology development fusion product.

The central cloud can be a cloud computing platform built on the cloud computing data center infrastructure based on the ability of cloud computing technology. By summarizing and analyzing complex and large-scale global data processing tasks, it can effectively realize huge Data volume storage and management.

Edge cloud: It is a cloud computing platform based on the core of cloud computing technology and edge computing capabilities. The central cloud and the Internet of Things terminal form an end-to-end technical architecture of "cloud-edge-terminal three-body collaboration". By placing network forwarding, storage, computing, and intelligent data analysis on the edge for processing, the response delay is reduced and the central cloud is relieved. pressure, reduce bandwidth costs, and provide cloud services such as network-wide scheduling and computing power distribution.

Compared with the central cloud or the traditional cloud computing platform, the edge cloud is a relative concept. The edge cloud is a cloud computing platform that is relatively close to the terminal. In other words, it is different from the central cloud or the traditional cloud computing platform. The central cloud or the traditional cloud Computing platforms can include data centers with large-scale resources and concentrated locations, while edge cloud nodes cover a wider network range, and therefore have the characteristics of being closer to terminals. The resource scale of a single edge cloud node is small, but the edge cloud node a large amount. The terminal in this embodiment refers to the demand side of the cloud computing service, for example, it may be a terminal or user end in the Internet, or a terminal or user end in the Internet of Things.

As shown in FIG. 1 , it is a system architecture diagram of an embodiment of the present application, including a central cloud, an edge cloud, a gateway, an electronic signage, and the like.

Specifically, the central cloud includes the central cloud business platform, cloud management server components, gateway communication agent, etc. The business platform of the central cloud realizes the multi-user system, the visual configuration and data storage of the electronic signage business, the visual operation and maintenance management and business operation of the electronic signage, and the visual operation and maintenance management and user relationship maintenance of the edge cloud. The cloud management server component realizes the registration management of the edge cloud, data monitoring, sending commands to the edge cloud and synchronizing user business data. The gateway communication agent realizes the data communication and command delivery with the electronic signage gateway.

The edge cloud is an autonomous node deployed on the user's edge side, including the edge cloud business platform, cloud management client components, distributed components, gateway communication agents, etc. The edge cloud business platform realizes the visualization of user business data, distributed creation and management, and business operations of electronic signage. The cloud management client component realizes cloud registration, monitoring data reporting, edge cloud-central cloud user business and command data reporting. The gateway communication agent realizes the data communication and order issuing with the electronic signage gateway. Distributed components realize distributed high availability of edge cloud and ensure data consistency.

The gateway is used to control the electronic signage within the user's area, and perform uplink and downlink data communication with the central cloud/edge cloud.

Specifically, FIG. 2 shows a flowchart of a request processing method provided by an embodiment of the present application. The method is applied to a central cloud server, which can provide cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN (Content Delivery Network, content distribution network), and cloud servers or server clusters for basic cloud computing services such as big data and artificial intelligence platforms.

Those skilled in the art should understand that the above servers are only examples, and other existing or future servers that are applicable to this application should also be included in the scope of protection of this application, and are included here by reference.

As shown in Figure 2, the method includes the following steps:

Step S201: Receive a display request from a client terminal for displaying a target electronic signage.

The embodiments of the present application can be applied to the field of computer technology, and specifically can be applied to an application scenario where a display request for displaying a target electronic sign is received, and the target electronic sign is controlled to display corresponding sign content in response to the display request.

Specifically, the target electronic signage can be an electronic signage that needs to display the content of the signage in the application scenario. The specific application scenarios include smart retail, smart office, and smart transportation. Take the conference office scene in the smart office scene as an example. Common electronic signage products include conference door signs, table signs and workstation signs, etc. For example, in the case that the signboard is a table card, the content of the signboard includes relevant information of the participants, such as one or more types of names, work units, positions, and the like. In the case that the sign is a work station sign, the contents of the sign include information on personnel at the work station, station reservation information, advertisement information, and the like. In the case that the sign is a conference room door plate, the content of the sign includes scheduling information, advertisement information, etc. of the meeting room.

The display request can be sent through the client installed on the terminal, for example, when the signage content needs to be displayed on the target electronic signage, the display request can be sent through the client. For example, in a conference office scenario, the terminal may be a terminal corresponding to a conference administrator. It should be noted that the conference administrator may be a terminal of a designated user participating in the conference, for example, a terminal held by the conference host; The application embodiment does not limit this.

Optionally, the display request may include the quantity of the target electronic signage, the code (Identity document, ID) of the target electronic signage, the signage content to be displayed by the target electronic signage, the preset display template for displaying the content of the signage, and the target electronic signage The display time of the content of the signage, the update time of updating the content of the signage, etc. are displayed.

Wherein, the preset display template is a predetermined template for displaying signage content, and the preset display template may include the font, font size, color, typesetting format, etc. of the display signage content.

Step S202: Determine the responder that responds to the display request according to the number of the requested target electronic signs in the display request and/or the estimated response time of the central cloud server to the display request.

Wherein, the responding end includes the central cloud server and/or an edge cloud server having a communication connection with the central cloud server.

Specifically, the responding end is a server that responds to the display request. Specifically, the responding end is used to obtain the signage content of the target electronic signage according to the display request, and send the signage content to the target electronic signage through gateways and other devices. A signage, controlling the target electronic signage to display the content of the signage.

When determining the responding end that responds to the response request, it may be determined that the central cloud server and/or with The edge cloud server serves as the responding end.

Optionally, when the number of the target electronic signs is small, or the expected response time is short, the central cloud server may be used as a responding end to respond to the display request. When the number of the target electronic signs is large, or the expected response time is long, the central cloud server and at least one edge cloud server may be used as responders to respond to the display request.

Specifically, the estimated response time may be determined according to idle processing resources and/or processing speed of the central cloud server. Wherein, the idle processing resource may be determined according to the utilization rate of the central processing unit (Central Processing Unit, CPU), the utilization rate of the graphics processing unit (Graphic Processing Unit, GPU), the utilization rate of the accelerated processing unit (Accelerated Processing Units, APU), etc. . It can be understood that the more idle processing resources and faster processing speed of the central cloud server, the shorter the expected response time; longer.

That is to say, in this embodiment of the application, when the number of target electronic signs is small, the idle processing resources of the central cloud server are large, and the processing speed of the central cloud server is fast, etc., the central cloud server may respond The display request; on the contrary, when the number of target electronic signs is large, the idle processing resources of the central cloud server are less, and the processing speed of the central cloud server is slow, etc., the central cloud server and the edge cloud server can Respond to the display request.

It should be noted that when the central cloud server and the edge cloud server respond to the display request, they may also be based on the number of target electronic signs, the idle processing resources of the central cloud server, and the processing speed of the central cloud server. situation, it is determined that one edge cloud server or multiple edge cloud servers respond. For example, when the number of target electronic signs is extremely large (for example, the number of target electronic signs is greater than the corresponding threshold), or the idle processing resources of the central cloud server are few (for example, the idle processing resources are less than the corresponding threshold), or the processing speed of the central cloud server is very slow (such as the processing speed is less than the corresponding threshold), when the amount of tasks to be responded is large, or the central cloud server has less idle processing resources and the processing speed is slower, the central cloud server and multiple edge cloud servers can be used to respond , to reduce task processing pressure and improve response speed.

Wherein, when the central cloud server and the edge cloud server respond to the display request, the central cloud server can communicate with the edge cloud server, and send the sign content of the target electronic signage to the edge cloud server, so as to realize sinking the data to the edge cloud server. The edge cloud server is used to control the display of the target electronic signage through the edge cloud server.

Optionally, the edge cloud server can connect to the central cloud server through communication protocols such as LwM2M, UDP, TCP, HTTP, and MQTT.

Determining the response end that responds to the display request can be determined according to the number of target electronic signs in the actual scene and the idle processing resources and processing speed of the central cloud server. In this way, it can be flexibly determined according to the actual scene requirements The display request is responded to by the central cloud server and/or the edge cloud server, which relieves the processing pressure of the central cloud server, reduces network bandwidth occupation, and reduces calculation delay.

Step S203: Respond to the display request based on the responder.

After the responder is determined, the display request may be responded based on the responder.

Specifically, when the central cloud server responds to the display request, the signage content and the preset display template of the target electronic signage can be obtained first according to the display request, and the signage content can be added to the preset display template , so that display files can be generated based on preset display templates that add signage content.

Then, send the display instruction and the display file to the preset gateway, so as to send the display file to the target electronic signage through the preset gateway, and instruct the target electronic signage to display the display file through the preset display template. The content of the label.

Wherein, in an actual scenario, the preset gateway may include but not limited to a Bluetooth gateway, a Wi-Fi (Wireless Fidelity, wireless fidelity technology) gateway, etc., which may be determined according to actual conditions.

In addition, when the central cloud server and at least one edge cloud server respond to the display request, the central cloud server can communicate with the edge cloud server and send the display file to the edge cloud server, so as to send the display file to the edge cloud server through the edge cloud server. It is assumed that the gateway sends a display instruction and the display file, and then sends the display file to the target electronic signage through the preset gateway, instructing the target electronic signage to display the signage content through the preset display template.

In the embodiment of the present application, according to the display request, the number of the requested target electronic signs and/or the expected response time of the central cloud server to respond to the display request, determine the responder that responds to the display request , based on the responding end, responding to the display request; in this way, it can be flexibly determined that the central cloud server and/or the edge cloud server respond to the display request according to the display requirements of the electronic signage in the actual scene and the data processing capability of the central cloud server The display request relieves the processing pressure of the central cloud server, reduces the network bandwidth occupation, and reduces the calculation delay.

In an embodiment of the present application, the determination of the responder that responds to the display request includes:

When it is determined that the number of the target electronic signs is less than a first preset threshold, and/or the expected response time is less than a second preset threshold, determine that the central cloud server is the responding end;

When it is determined that the number of the target electronic signs is greater than a first preset threshold, and/or the expected response time is greater than a second preset threshold, it is determined that the central cloud server and at least one edge cloud server are the Response end.

Specifically, in an actual scenario, when determining the responding end, the number of the target electronic signs and the expected response time may be compared with corresponding thresholds.

For example, it may be determined that the central cloud server is the responding end when the number of the target electronic signs is less than a first preset threshold, and/or the expected response time is less than a second preset threshold; If the number of the target electronic signs is greater than the first preset threshold, and/or the expected response time is greater than the second preset threshold, determine the central cloud server and at least one edge cloud server as the responding end .

Optionally, the second preset threshold may be set as the response duration carried in the display request, and the carried response duration may be understood as the maximum response duration set by the client to respond to the display request.

In some embodiments, when the number of the target electronic signs is greater than a third preset threshold, and/or the expected response time is greater than a fourth preset threshold (the third preset threshold is greater than the first preset threshold; the second Four preset thresholds are less than the second preset threshold), that is, the number of target electronic signs is extremely large, or the maximum response time set by the client is very short, that is, when the real-time requirement for responding to the display request is extremely high , a central cloud server and multiple edge cloud servers may be determined as the responding end.

In one embodiment of the present application, when it is determined that the central cloud server is the responding end,

The responding to the display request based on the responding end includes:

Obtaining the signage content of the target electronic signage, and adding the signage content to a preset display template to generate a display file;

sending a display instruction and the display file to a preset gateway, so as to send the display file to the target electronic signage through the preset gateway, instructing the target electronic signage to display the sign through the preset display template content.

Specifically, when the central cloud server responds to the display request, that is, when the number of target electronic signs is small, the central cloud server has more idle processing resources, and the central cloud server has a faster processing speed, etc., The signage content and the preset display template of the target electronic signage can be obtained first according to the display request, and the signage content can be added to the preset display template, so that the display file can be generated based on the preset display template for adding the signage content .

Then, send the display instruction and the display file to the preset gateway, so as to send the display file to the target electronic signage through the preset gateway, and instruct the target electronic signage to display the display file through the preset display template. The content of the label.

As an example, in combination with FIG. 3 , the following describes the processing flow of the central cloud server as the responder in an actual scenario.

Step 2: The gateway (that is, the preset gateway in the embodiment of the present application) is connected to the Internet; the user can access the WEB page provided by the gateway to configure the address of the central cloud server.

Step 3: The user can add a gateway to the service platform of the central cloud server, and configure the gateway, for example, configure communication channels, search time, interface addresses, etc.

Step 4: After the gateway goes online, the gateway automatically connects to the central cloud server. After passing the verification of the central cloud server, the gateway obtains the configured data (communication channel configuration, search time, interface address) from the central cloud server.

Step 5: Users can add electronic signs and enable the automatic search function of the gateway. After the gateway searches for electronic signs within the search range, it binds the electronic signs and then reports the information of the electronic signs to the central cloud server.

Step 6: The user creates a display template of the electronic signage (that is, the preset display template in this embodiment of the application), and configures the display template.

Step 7: The user selects the target electronic signage to be used, and binds the display template.

Step 8: When the refresh conditions of the electronic signage are satisfied, the central cloud server generates display files and display instructions according to the templates bound to the electronic signage and signage content, and sends the display files and display instructions to the gateway, and then sends the display files to The target electronic signage displays the content of the signage through the target electronic signage.

In an embodiment of the present application, when it is determined that the central cloud server and at least one edge cloud server are the responding end,

The responding to the display request based on the responding end includes:

Obtaining the signage content of the target electronic signage, and adding the signage content to a preset display template to generate a display file;

Establish a communication connection with the target edge cloud server; send the display file to the target edge cloud server, so as to send a display instruction and the display file to the preset gateway through the target edge cloud server, and send the display file to the default gateway through the target edge cloud server The display file is sent to the target electronic signage, instructing the target electronic signage to display the signage content through the preset display template.

When the central cloud server and at least one of the edge cloud servers respond to the display request, on the one hand, the central cloud server can first obtain the signage content and the preset display template of the target electronic signage according to the display request, and then The signage content is added to the preset display template, so that the display file can be generated based on the preset display template to which the signage content is added.

On the other hand, the central cloud server can communicate with the edge cloud server, and send the above-mentioned display file to the edge cloud server, so as to send display instructions and the display file to the preset gateway through the edge cloud server, and then pass the preset gateway sending the display file to the target electronic signage, instructing the target electronic signage to display the signage content through the preset display template.

As an example, the following describes the processing flow in an actual scenario with the central cloud server and the edge cloud server as the responding end in conjunction with FIG. 4 .

Step 1: The user can access the service platform of the edge cloud server through the WEB, and log in with the default account.

Step 2: The user configures the central cloud server address and security certificate on the business platform of the edge cloud server, and records the system number of the edge cloud server at the same time.

Step 3: The edge cloud server automatically connects to the central cloud server according to the configured central cloud server address and security certificate.

Step 4: The user accesses the service platform of the central cloud server through WEB, registers an account and logs in.

Step 5: The user adds an edge cloud server (the edge cloud server whose system number was recorded in step 2) on the business platform of the central cloud server.

Step 6: The central cloud server sends the change command of the electronic signage user to the edge cloud point; the edge cloud server clears the historical data after receiving the change command.

Step 7: The gateway (that is, the preset gateway in the embodiment of the present application) is connected to the Internet; the user can access the WEB page of the gateway to configure the address of the central cloud server.

Step 8: The user can add a gateway to the service platform of the central cloud server, and configure the gateway, for example, configure the communication channel, search time, interface address, etc. The central cloud server writes gateway data to the edge cloud server, and writes the edge cloud server address to the gateway.

The user selects the target electronic signage to be used and binds the display template.

Step 13: The central cloud server generates a display file according to the template bound to the electronic signage and the content of the signage, and sends the display file to the edge cloud server.

Step 14: When the refresh conditions of the electronic signage are satisfied, the edge cloud server sends the display file and display command to the gateway, and then sends the display file to the target electronic signage through the gateway, and displays the content of the signage through the target electronic signage.

In the above process, the data sinks to the edge cloud server. In this way, when the central cloud server is abnormal, down, or the network is abnormal, the edge cloud server can realize offline autonomy and normal business operation, which improves the use efficiency of electronic signs and reduces The system pressure of the central cloud server.

In one embodiment of the present application, when the edge cloud server includes multiple servers, after the display file is generated, the method further includes:

Determine a target edge cloud server in the edge cloud servers according to the random timeout period corresponding to each edge cloud server;

Establish a communication connection with the target edge cloud server.

Specifically, when the number of target electronic signs is extremely large, or the maximum response time set by the client is very short, that is, when the real-time requirement for responding to the display request is extremely high, the central cloud server and multiple edge The cloud server acts as the responding end.

Among the multiple edge cloud servers, it is necessary to determine a target edge cloud server as a management node according to the random timeout period corresponding to each edge cloud server, and receive the display file sent by the central cloud server through the management node, and The display file is sent to other edge cloud servers, and the corresponding task of responding and displaying the target electronic signage is assigned to other edge cloud nodes. For example, when responding to a display request, the management node determines the electronic signage to be displayed by each edge cloud server.

Optionally, the determination of the target edge cloud server in this embodiment of the application can be implemented through an election process. The election process will be described below in conjunction with FIG. 5:

For example, there are three edge cloud servers, and the three edge cloud servers are respectively marked as node A, node B, and node C.

Before the election, the term number is 0, each node is a Follower (follower), and each node has a random timeout. Wherein, the random timeout period of node A is 100ms (milliseconds), the random timeout period of node B is 120ms, and the random timeout period of node C is 150ms.

During the election, the random timeout of node A is the smallest. Therefore, node A wakes up first and is successfully promoted to Candidate (candidate). The term number becomes 1. Node A self-votes, and then initiates a request to vote to other Followers.

After node B and node C receive the voting request from node A, they will judge whether they have voted in the election with the term number 1. If not, they will vote for A, and set their term number as 1, and Resets own random timeout.

Node A wins the majority of votes in the election with term number 1 and becomes the Leader (management node) of this term. In order to maintain the identity of the management node, node A will continuously send heartbeats to node B and node C (heartbeats can be understood as instructions), instructing node B and node C to reset the random timeout to prevent B and C from re-initiating voting.

It should be noted that if the random timeout time of each node is the same, the node that first obtains the majority of votes will become the Leader, and the other Candidates will return to Follower. If the number of votes is the same, all nodes will return to Follower, reset the random timeout time, and prepare for the next round of elections.

When the Leader goes down, all nodes will re-elect a new Leader, and the new Leader will continue to communicate with the central cloud server according to the original registration information.
