Remote smart devices, such as smart express cabinets, smart vending cabinets or smart food pickup cabinets, usually need to establish a communication connection with a business server, so that data transmission can be performed between the remote smart device and the business server, so as to realize the related functions of the remote smart device.

Taking the smart express cabinet as an example, when the user needs to store or take out the goods, a request to open the door will be sent to the business server. After receiving the door opening request, the business server will issue relevant instructions to the smart express cabinet to open the corresponding cabinet door.

In this process, the smart express cabinet needs to upload its own status data in advance, such as the current cabinet occupancy status, to the business server, so that the business server can allocate available cabinets to users according to the occupied cabinet status when receiving the door opening request. grid. At the same time, the business server also needs to transmit relevant instructions to the smart express cabinet when receiving the user's request to open the door, so as to control the intelligent express cabinet to open the corresponding cabinet door in time, so as to facilitate the user to store or take out the goods.

In the prior art, the remote smart device usually communicates with the service server through a mobile communication system (3G/4G/5G). However, in a state of poor network conditions, the key information sent by the service server to the remote smart device is often inaccessible, which may easily cause communication obstacles and bring losses, and it is difficult to ensure communication quality.

In this regard, embodiments of the present invention provide a communication control method and apparatus, so as to improve the communication quality between a remote intelligent device and a service server.

FIG. 1 is a schematic diagram of an application system according to an embodiment of the present invention. As shown in FIG. 1 , the application system includes a business server 11 , a decision server 12 and a remote intelligent device.

The remote intelligent device in this embodiment is described by taking the intelligent express cabinet 13 as an example. The business server 11 is a server that performs data transmission with the smart express cabinet 13, and the business server 11 needs to realize the relevant service functions of the smart express cabinet 13 through data transmission, such as opening the cabinet door, data uploading and distribution. Cabinets etc. The decision server 12 is used to determine the communication protocol adopted by the business server 11 and the smart express locker 13 .

It should be understood that the relevant service function may be specifically determined according to the device type of the smart device. Different types of devices have different related service functions. For example, for a smart vending machine, the related service functions should also include a settlement function.

Specifically, the service server 11 and the smart express cabinet 13 use a preset communication protocol to establish a communication connection and transmit data. In the process of data transmission, the decision server 12 will acquire the device information of the smart express cabinet 13 and the communication-related data between the smart express cabinet 13 and the business server 11, and then use the pre-trained data according to the acquired device information and communication-related data. The communication protocol decision model determines the target communication protocol that meets the network transmission requirements of the current communication scenario, and notifies the service server 11 and the smart express cabinet 13 of the target communication protocol, so that the service server 11 and the smart express cabinet 13 use the target communication protocol to transmit data.

Wherein, the communication protocol is used to indicate the data transmission rule between the target device and the service server.

Specifically, in the seven-layer network protocol of the OSI model (Open System Interconnection Reference Model, Open System Interconnection Reference Model), each layer has many kinds of protocols. For example, 4G, Wi-Fi, etc. at the physical layer and data link layer, UDP protocol (User Datagram Protocol), TCP protocol (Transmission Control Protocol) at the transport layer, HTTP protocol at the application layer (Super Text transfer protocol, Hyper Text Transfer Protocol), MQTT protocol (Message Queuing Telemetry Transport), etc. Among them, the hierarchy, reliability and validity of each communication protocol are different, and the data packet size required to transmit the same valid data content is different. Different communication protocols should be selected for different communication scenarios. For example, communication using HTTP is more reliable than using MQTT, but less effective. Communication using TCP is more reliable than using UDP, but less effective.

In this embodiment, the decision server 12 may select a better communication protocol between the two according to the current communication scenario between the business server 11 and the smart express locker 13 .

For example, when the communication scenario between the business server 11 and the smart express cabinet 13 has high requirements for stability, the decision server 12 will select a relatively stable and reliable communication protocol. However, in a communication scenario with poor network conditions, the decision server 12 may relatively select a more effective communication protocol.

It should be understood that the communication scenario in this embodiment should comprehensively consider the data type of the currently transmitted data, the network state, and other factors that may have an impact. For example, the network quality of the environment where the device is located, the importance of the transmitted data, and the importance of the target device, etc. The selected communication protocol is a relatively optimal communication protocol over the communication scenario.

FIG. 2 is a flowchart of a communication control method according to an embodiment of the present invention. As shown in Figure 2, the communication control method specifically includes the following steps:

S100. Acquire device information of a target device and communication-related data between the target device and a service server.

Wherein, the target device is a remote intelligent device that performs data transmission with the service server. In this embodiment, the target device may specifically be an intelligent express cabinet.

Specifically, the target device will first establish a communication connection with the service server by using a predetermined communication protocol. The predetermined communication protocol may be a communication protocol with wide applicability that can be applied in various scenarios. After the communication connection is established, normal data transmission will be performed between the target device and the service server, and the decision server can obtain the device information of the target device and the communication-related data between the target device and the service server at this time.

Optionally, the device information may include hardware parameters and network service parameters supported by the target device.

Specifically, the hardware parameters include device interface type, device ID, and device type. The network service parameters include network operator information corresponding to the target device, network type, domain name resolution (DNS, Domain name resolution), router address, wireless local area network service set identifier (WIFI SSID, WIFI Service Set Identifier), wireless local area network physical address ( One or more of WIFI MAC, Media Access Control Address), Internet Protocol (IP, Internet Protocol) address, signal strength, and Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol).

The interface type is a data transmission interface type supported by the target device. The device ID is the unique identifier of the target device. The device type is the device type described by the target device, for example, a smart express cabinet, a smart food pickup cabinet, or a smart vending cabinet.

The network operator information is the network operator to which the target device currently uses the network to which it belongs. The network type is an available network type supported by the target device, such as 2G, 3G, 4G, or a wireless local area network. The domain name resolution, router address, wireless local area network service set identifier, wireless local area network physical address, Internet protocol address and dynamic host configuration protocol are all relevant addresses corresponding to the target device or relevant protocols supported by the target device. The signal strength is the strength of the signal transmitted by the target device.

Optionally, the communication-related data may include data types and network state parameters of data transmitted between the target device and the service server. Wherein, the network state parameter may be used to represent the network state of the current transmission process.

Specifically, the data type can be determined according to the relevant identifiers in the transmitted data. For example, for a smart express cabinet, the identifier of the door opening instruction sent by the service server to the smart express cabinet can be A, and the smart cabinet is performing the door opening operation. The identifier of the feedback information returned afterward may be B, and the identifier of the cabinet status data uploaded by the smart express cabinet may be C. The decision server may determine the type of transmitted data based on the identification in the transmitted data.

The network state parameter may be determined according to the historical communication records of the target device and the service server within a statistical period. Wherein, the historical communication record is a communication record generated by the target device and the service server in a statistical period, and the communication record includes the communication time and communication result of each communication.

FIG. 3 is a flowchart of a method for determining a network state parameter according to an embodiment of the present invention. As shown in FIG. 3 , the method for determining network state parameters specifically includes the following steps:

S110. Acquire the communication time and the corresponding communication result in the historical communication record.

Specifically, the communication time and the corresponding communication result recorded in the historical communication record are obtained.

S120. Determine the network state parameter according to the communication time and the communication result.

Wherein, the network state parameter includes at least one of a communication reach rate, a communication speed, and the number of consecutive communication failures. The communication reach rate is used to represent the probability of successful communication, and the value of the communication reach rate may specifically be the ratio of the number of successful communications to the total number of communications in a statistical period. The communication speed is used to represent the communication transfer rate, and the value of the communication speed may specifically be the average time taken by the service server from initiating communication to receiving communication feedback. The number of consecutive communication failures may specifically be the maximum consecutive number of times that the service server initiates communication but fails to receive communication feedback within a preset time period.

It should be understood that the network state parameters may be determined according to actual conditions. The network state parameter should reflect the network state in the current communication process to the greatest extent.

S200. Using the device information and the communication-related data as inputs, determine a target communication protocol based on a pre-trained communication protocol decision model.

Wherein, the communication protocol decision model is used to determine a communication protocol that meets the network transmission requirements of the target device.

Specifically, after acquiring the device information and the communication-related data, the decision server will input the device information and the communication-related data into the communication protocol decision model to obtain the target communication protocol. The target communication protocol is determined by the communication protocol decision model and can meet the current network transmission requirements of the target device and the service server.

Optionally, the communication protocols involved in this embodiment include, but are not limited to, the UDP protocol, the COAP protocol (The Constrained Application Protocol), the TCP protocol, the IP protocol (Internet Protocol, Internet Protocol), the HTTP protocol, and the RPC protocol (Remote Procedure Call). , Remote Procedure Call) and MQTT protocol. The communication protocol decision model can select a better communication protocol from the above communication protocols that meets the network transmission requirements.

It should be understood that after selecting the better communication protocol, both the target device and the service server can call the protocol interface corresponding to the better communication protocol for data transmission.

FIG. 4 is a flowchart of a method for determining a target communication protocol according to an embodiment of the present invention. As shown in Figure 4, the method for determining the target communication protocol includes the following steps:

S210. Determine the network transmission requirement that conforms to the data type.

Wherein, the network transmission requirement is determined by the communication protocol decision model, and is used to represent the network condition to be satisfied by the target device and the service server in the current communication scenario. The network transmission requirement may specifically be a parameter range within which each parameter of the network state parameters obtained by the communication protocol decision model through calculation should be.

For example: when the data type of the data currently transmitted by the target device and the service server is the door opening command, and this communication scenario has high requirements for the communication reach rate, it is determined that the communication reach rate in the network transmission requirement should be in a high range , for example within 95%-100%.

Another example: when the data type of the data currently transmitted by the target device and the service server is cabinet state data, this communication scenario does not require too high requirements for the communication reach rate, then it is determined that the communication reach rate in the network transmission requirement can be in the Relatively low range, such as within 80%-100%.

That is, the specifics of each parameter range in the network transmission requirement should conform to the communication scenario, so as to ensure the user's experience in using the device. The data type can reflect the current communication scene to a certain extent.

Specifically, after the device information and communication-related data are input into the communication protocol decision model, the communication protocol decision model will determine the network transmission requirements that meet the current communication scenario according to the data type.

It should be understood that when the communication protocol decision model determines the network transmission requirement, the factors referred to are not limited to the data type of the transmitted data. That is, the network transmission requirements can also be determined according to other relevant information, such as the network quality in the environment where the device is located, the importance of the transmitted data, the communication frequency, and the device type, so that the determined network transmission requirements are consistent with the current communication scenario. Be as consistent as possible.

For example, when the target device is placed in an environment with poor network quality, such as an urban area, the network transmission requirement can be appropriately reduced. When the target device is placed in an environment with better network quality, such as suburban areas, the network transmission requirements can be appropriately increased.

Another example: when the importance of the transmitted data is low, the network transmission requirement can be appropriately reduced. When the importance of the transmitted data is high, the network transmission requirements can be appropriately increased.

S220. In response to the network state parameter meeting a network communication mode switching trigger condition, determine the target communication protocol according to the device information, the data type and the network state parameter.

Wherein, the network state parameter satisfying the network communication mode switching trigger condition is used to indicate that the network state parameter does not meet the network transmission requirement.

Specifically, after determining the network transmission requirement that conforms to the current communication scenario, the current network state parameter can be compared with the determined network transmission requirement. If the network state parameter satisfies the network communication mode switching trigger condition, it indicates that the current network The state cannot meet the network transfer requirements required for data transfer. The communication protocol decision model determines the target communication protocol according to the device information, data type and network state parameters. The target communication protocol is an optimal communication protocol that can meet the current network transmission requirements of the target device and the service server.

Optionally, the specific determination condition that the network state parameter satisfies the network communication mode switching trigger condition may be that any one of the network state parameters exceeds the corresponding parameter range set in the network transmission requirement.

For example, if the communication reach rate in the network status parameter is 80%, and the range of the communication reach rate set in the network transmission requirement is 90%-100%, the network status parameter satisfies the trigger condition for switching the network communication mode.

It should be understood that, in practical applications, the output of the communication protocol decision model should specifically be scores for different communication protocols. Among them, the communication protocol with the highest score is the target communication protocol.

S300. Notify the target device and the service server of the target communication protocol, so that the target communication protocol is used for data transmission between the target device and the service server.

Specifically, after the communication protocol decision model determines the target communication protocol, the decision server will notify the target device and the service server of the target communication protocol, so that the target device and the service server use the target communication protocol for data transmission.

After acquiring the device information of the target device and the communication-related data between the target device and the service server, the communication control method according to the embodiment of the present invention takes the device information and the communication-related data as inputs, and uses the pre-trained communication protocol as input. The decision-making model determines the target communication protocol, and then informs the target device and the service server of the target communication protocol, so that the target device and the service server use the target communication protocol for data transmission. The communication protocol decision model is used to determine a communication protocol that meets the network transmission requirements of the target device, and the communication protocol is used to indicate the data transmission rules between the target device and the service server. The communication quality can be improved by the method.

FIG. 5 is a flowchart of a method for training a communication protocol decision model according to an embodiment of the present invention. As shown in Figure 5, the communication protocol decision model training method includes the following steps:

S410. Obtain static data.

The static data is used to represent hardware parameters and network service parameters supported by the target device.

Wherein, the hardware parameters and network service parameters are similar to the hardware parameters and network service parameters obtained in step S100, and will not be repeated here.

S420. Obtain dynamic data.

Wherein, the dynamic data is related data generated during the data transmission process between the target device and the service server, and the dynamic data includes positive dynamic data and negative dynamic data. The positive dynamic data and the negative dynamic data are used to generate positive sample data and negative sample data, respectively.

It should be understood that the normal operation of the target device can be maintained during the process of acquiring the dynamic data in this embodiment, that is, the dynamic data can be acquired in this embodiment without affecting the normal operation of the target device.

Specifically, FIG. 6 is a flowchart of a method for acquiring dynamic data according to an embodiment of the present invention. As shown in Figure 6, the dynamic data acquisition method includes the following steps:

S421. Notify the target device and the service server of the first communication protocol in the communication protocol set, so that the target device and the service server use the first communication protocol for data transmission.

Wherein, the communication protocol set includes a plurality of communication protocols with a predetermined priority order. The communication protocol in the communication protocol set is determined according to the type of communication protocol supported by the target device. The priority of each communication protocol in the communication protocol set may be determined according to the applicability of the communication protocol. For example, a communication protocol with wider adaptability has a higher priority, and a communication protocol with less adaptability has a lower priority.

Specifically, the communication protocol in the communication protocol set is determined according to the communication protocol type supported by the target device. Notifying the target device and the service server of the first communication protocol in the communication protocol set, that is, the communication protocol with the highest priority, so that the target device and the service server use the first communication protocol for data transmission.

S422: Acquire a sample data type and a sample network parameter of the data transmitted between the target device and the service server under the first communication protocol.

Specifically, the sample data type and sample network parameters of the data transmitted between the target device and the service server under the first communication protocol are acquired. The sample data type is the data type of the data transmitted between the target device and the service server, and the sample network parameter is used to represent the network state in the current communication scenario.

S423. Determine the corresponding network connection condition according to the sample data type.

Wherein, the network connection condition is used to represent the network condition that needs to be satisfied when transmitting the data of the corresponding data type. The network connection condition may specifically be a parameter range that each parameter in the network state parameters manually input by the tester should be in.

S424. In response to any one of the sample network parameters exceeding the corresponding parameter range set in the network connection condition, switch the communication protocol between the target device and the service server to the communication protocol in the communication protocol set The communication protocol of the next priority until the target sample network parameters are determined.

Wherein, none of the target sample network parameters exceeds the corresponding parameter range set in the network connection condition.

Specifically, after the network connection conditions are determined, if any parameter in the sample network parameters exceeds the corresponding parameter range set in the network connection conditions, the communication protocol used between the target device and the service server is switched to the communication protocol set in the set of communication protocols. The next priority communication protocol until the target sample network parameters are determined. None of the parameters in the target sample network parameters exceeds the corresponding parameter range set in the network connection conditions.

S425. Determine the sample data type, the target sample network parameter, and the corresponding target communication protocol as the forward dynamic data.

Specifically, after the target sample network parameters are found, the sample data type, target sample network parameters and target communication protocol at this time are determined as forward dynamic data.

It should be understood that the target device and the service server will communicate using the target communication protocol. Until the communication scenario is changed so that the target sample network parameters cannot meet the network connection conditions corresponding to the changed communication scenario, step S424 is performed again to determine a new target communication protocol and record the corresponding forward dynamic data. Wherein, when step S424 is performed again, the switching will be performed again from the communication protocol with the highest priority in the communication protocol set.

For example, the currently determined target communication protocol is the fourth priority communication protocol in the communication protocol set. When the fourth-priority communication protocol does not meet the network connection conditions corresponding to the changed communication scenario, it is necessary to start switching from the first-priority communication protocol in the communication protocol set again.

S426: Determine the sample data type, the switched communication protocol and the corresponding sample network parameter before the target communication protocol as the negative dynamic data.

Specifically, the sample data type, the switched communication protocol and the corresponding sample network parameter before the target communication protocol are determined as negative dynamic data.

Optionally, if the target communication protocol is still not found after switching all communication protocols in the communication protocol set, in order to meet the normal use of the target device, the communication corresponding to the sample network parameter that meets the maximum number of network connection condition items can be selected. The protocol is the target communication protocol.

Specifically, in response to the target sample network parameter not being determined, the communication protocol corresponding to the sample network parameter that satisfies the largest number of network connection condition items is determined as the target communication protocol.

Through steps S421-S426, the communication quality between the target device and the service server can be improved and dynamic data can be collected without affecting the normal operation of the target device.

S430. Generate positive sample data and negative sample data according to the static data and the dynamic data.

Specifically, after the static data and dynamic data are collected, positive sample data and negative sample data are generated.

Wherein, the positive sample data is generated from forward dynamic data and static data. The negative sample data is generated from negative dynamic data and static data.

S440. Train the communication protocol decision model according to the positive sample data and the negative sample data.

Specifically, the positive sample data and negative sample data are input into the preset model to be trained, the preset model will be trained according to the input positive sample data and negative sample data, and the trained preset model can be used as The communication protocol decision model is used.

The preset model may be a model established based on PMML (Predictive Model Markup Language, Predictive Model Markup Language). In practical applications, the trained PMML model can output scoring results for different communication protocols according to the input data.

As shown in FIG. 7 , 72 is a dynamic data acquisition part, and the dynamic data acquisition part 72 includes network connection conditions and communication protocol sets corresponding to each data type input in advance by the tester.

The dynamic data acquisition part 72 notifies the target device 74 and the service server 73 of the communication protocol with the first priority in the communication protocol set, so that the target device 74 and the service server 73 communicate using the communication protocol of the first priority. The dynamic data acquisition part 72 will compare the sample network state parameters at this time with the network connection conditions corresponding to the data types of the transmitted data. When the sample network state parameter satisfies the network connection condition, the communication protocol between the target device 74 and the service server 73 is maintained. When the sample network state parameters do not meet the network connection conditions, the communication protocol used between the target device 74 and the service server 73 is switched to the next-level communication protocol in the communication protocol set, so as to keep the network state parameters at each moment satisfied Internet connection conditions.

The data types, network state parameters and communication protocols corresponding to the network state parameters transmitted in the communication process will be collected by the collecting part 75 and transmitted to the communication protocol decision model for training of the communication protocol decision model.

When data transmission is required, the target device 74 and the service server 73 will first use a predetermined communication protocol to communicate. The collection part 75 acquires the communication-related data and the device information of the target device generated during the communication process, and inputs the acquired communication-related data and device information into the communication protocol decision model 71 . After receiving the communication-related data and device information, the communication protocol decision model 71 will continuously detect the current network state. When it is detected that the network state is poor, the communication protocol decision model 71 will output the target communication protocol and notify the target device 74 and the service server 73, so that the target device 74 and the service server 73 use the target communication protocol for data transmission. The relevant data generated during the communication between the target device 74 and the service server 73 using the target communication protocol will still be collected by the collection part 75 for optimizing the communication protocol decision model 71 .
