[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] An embodiment of the present application provides a remote control method, which is applied to a control system. The control system includes a server and multiple clients. The client includes a controller. The method is described in detail in conjunction with the execution process of the remote control method.

[0024] S101: Establish a message queue telemetry transmission protocol connection between the controller in the client and the server.

[0025] Here, the Message Queuing Telemetry Transport Protocol (MQTT protocol) is a lightweight publish-subscribe message transmission protocol, which is usually used for communication in low-bandwidth, high-latency or unreliable network environments. It is particularly suitable for scenarios such as the Internet of Things, mobile applications and remote sensors.

[0026] The controller may include a BMC (Baseboard Management Controller), an MCU (Microcontroller Unit), a PLC (Programmable Logic Controller), a GPU (Graphics Processing Unit), and the like.

[0027] Here, the server end may be an operating system of the server, such as an OS (Operating System).

[0028] Here, an MQTT protocol connection is established between a server and multiple client controllers.

[0029] S102: The server obtains one or more of task information, the location of the controller, the device capability of the device corresponding to the controller, and the priority of the controller.

[0030] Here, the task may include controlling the BMC corresponding device to perform operations such as power on and off, or controlling the MCU corresponding device to perform operations such as cabinet opening and unlocking.

[0031] Here, mission information may include objectives, requirements, performance indicators, resource requirements, location dependencies, security, and budget constraints, etc.

[0032] Here, the location of the controller may include being located at a core position or an edge position of the system.

[0033] Here, device capabilities may include computing capabilities, network capabilities, and storage capabilities.

[0034] Among them, each controller supports the MQTT protocol.

[0035] S103: The server determines a command controller and an execution controller in at least one controller according to one or more of the task information, the location of the controller, the device capability of the device corresponding to the controller, and the priority of the controller.

[0036] Here, the command controller is used to send control commands, and the execution controller is used to receive and execute control commands.

[0037] Among them, the BMC can be a command controller or an execution controller; the MCU can be an execution controller.

[0038] The command controller may include one or more controllers, and the execution controller may include one or more controllers.

[0039] Among them, when the controller is located at the core position of the system, the controller is selected as the command controller, and the controller close to the controlled device is selected as the execution controller.

[0040] Among them, when the corresponding device of the controller supports high-speed and stable network connection, and can store a large amount of historical data or configuration information, the controller is used as a command controller; when the corresponding device of the controller has a dedicated interface, low-power design and real-time performance, the controller is used as an execution controller.

[0041] Among them, the controller with higher priority serves as the command controller, and the controller with lower priority serves as the execution controller.

[0042] In one embodiment, a weight can be assigned to each parameter based on the task information. For example, if the task has high real-time requirements, a higher weight is assigned to the location and device capabilities; if the task has high global optimization requirements, a higher weight is assigned to the task and priority.

[0043] S104: The execution controller receives, through the server, a control message issued by the command controller through the message queue telemetry transmission protocol, and controls the device corresponding to the execution controller according to the control message.

[0044] Among them, control messages may include control operations such as powering on, powering off, reading device status information, reading sensor readings, opening a cabinet, unlocking, upgrading firmware, restarting the machine, setting startup items, and configuring BIOS (Basic Input / Output System) options.

[0045] Specifically, when the execution controller is a BMC, the corresponding device may be an edge server; when the execution controller is an MCU, the corresponding device may be a sensor.

[0046] Specifically, the command controller generates a control command, sends it to the server, and the server forwards it to the execution controller.

[0047] In one embodiment, the server may also generate and send a control message to the controller.

[0048] In one embodiment, the execution controller can be configured to perform periodic reporting, such as reporting heartbeat information.

[0049] In one embodiment, the execution controller can proactively report information when establishing a connection or when information changes. For example, this can be done by defining the subject as BMC / {PN} / status and setting the Quality of Service (QoS) to 1. BMC represents the message type sent by the BMC, and PN is the machine PN extracted after the BMC reads the entire machine's fru information. Status indicates that the content sent is basic information corresponding to the PN, including boot information and asset information.

[0050] It should be noted that this application establishes an MQTT protocol connection between the controller and the server. Without introducing other protocols, the MQTT protocol can be used alone to control the corresponding devices through the controller, and batch operations can be performed on the controller to achieve cluster control. At the same time, interconnection can be achieved between the server, BMC and MCU, facilitating remote function development and implementation.

[0051] In some embodiments, establishing a message queue telemetry transport protocol connection between a controller in a client and a server includes:

[0052] The controller in the server and client establishes a transmission control protocol connection;

[0053] Based on the Transmission Control Protocol, the server sends a message to the controller in the client requesting to establish a message queue telemetry transport protocol connection;

[0054] The controller in the client returns a reply message to the server;

[0055] In response to the reply message received by the server being a connection consent message, a message queue telemetry transmission protocol connection is established between the controller in the client and the server.

[0056] Here, the Transmission Control Protocol is a connection-oriented, reliable transport layer communication protocol that provides reliable data transmission services between application programs on different hosts in the network.

[0057] Here, a message is a data unit exchanged between two nodes in a network. It can carry control information or application data. A message usually consists of a header, a payload, optional options, and a trailer.

[0058] The reply message may include a connection approval message and a connection disapproval message.

[0059] In one embodiment, the transmission control protocol connection failure may be determined by the interruption of the transmission control protocol connection monitoring or the inability to ping the management platform IP.

[0060] In this way, by combining the transmission control protocol with the message queue telemetry transmission protocol connection, transmission stability and reliability can be guaranteed, while also providing efficient and flexible message delivery capabilities; at the same time, unified sending and receiving protocols can reduce the hardware pressure on the server side and improve the efficiency of server-side software development.

[0061] In some specific embodiments, the server determines a command controller and an execution controller in at least one controller based on one or more of task information, a location of the controller, device capabilities of a device corresponding to the controller, and a priority of the controller, including:

[0062] Determining, based on the task information, an importance ranking of one or more of a location of the controller, a device capability of a device corresponding to the controller, and a priority of the controller;

[0063] Sort by importance and build a judgment matrix;

[0064] Calculating, by using a judgment matrix, a weight of one or more of a position of the controller, a device capability of a device corresponding to the controller, and a priority of the controller;

[0065] Calculating a score for at least one controller based on one or more of a location of the controller, a device capability of a device corresponding to the controller, and a priority of the controller in combination with a weight;

[0066] A command controller and an execution controller are determined in at least one controller according to the score.

[0067] Here, the importance of each parameter varies according to different task information.

[0068] Among them, according to the score, the one with high score is used as the command controller and the one with low score is used as the execution controller.

[0069] Here, the data in the judgment matrix is the importance score between each two parameters.

[0070] Specifically, a judgment matrix is constructed based on the importance ranking. For example, assuming that the task information is ranked by importance as location, equipment capability, and priority, the importance scores between location and equipment capability, location and priority, and equipment capability and priority are calculated based on a preset comparison rule. The comparison rule can be a 1-9 scale, where 1 means factors A and B are equally important; 3: Factor A is slightly more important than B; 5: Factor A is significantly more important than B; 7: Factor A is strongly more important than B; and 9: Factor A is extremely more important than B. If B is more important than A, a score is used to represent this. For example, if B is slightly more important than A, A's score is 1 / 3.

[0071] Specifically, according to the importance score between each parameter and other parameters, the geometric mean of the parameter is calculated, and the geometric mean is normalized to obtain the weight of the parameter.

[0072] In one embodiment, the judgment matrix is checked for consistency by calculating consistency indicators, randomly querying consistency indicators, and / or calculating consistency ratios. A dynamic feedback mechanism can also be designed to adjust weights and scores in real time based on task execution and system status. In addition, a machine learning algorithm can be introduced to optimize weight distribution based on historical data. This can improve the accuracy of weights.

[0073] In this way, by using the hierarchical analysis method to determine the command controller and the execution controller, the combination of qualitative and quantitative analysis can be achieved, the results obtained are more accurate, and resource allocation is optimized.

[0074] In some specific embodiments, the execution controller receives, through the server, a control message published by the command controller through a message queue telemetry transmission protocol, including:

[0075] According to the topic of the control message corresponding to the command controller, the execution controller subscribes to the topic of the control message;

[0076] According to the status feedback topic corresponding to the execution controller, the command controller subscribes to the status feedback topic.

[0077] Here, topics are used to categorize and route messages, allowing publishers and subscribers to exchange information through well-defined topics.

[0078] The status feedback may be the return of the execution result or the reporting of status information.

[0079] For example, assuming that the command controller is a BMC, the subject of the control message may be bmc / control; assuming that the execution controller is an MCU, the subject of the status feedback may be mcu / sensor_data.

[0080] Specifically, the command controller publishes a control message, and since the execution controller subscribes to the topic of the control message, the execution controller can receive the execution message. For example, the message can be forwarded by the server.

[0081] In this way, publishers and subscribers can be made independent of each other, enhancing the flexibility of the system; supporting one-to-many message propagation and improving communication efficiency.

[0082] In some specific embodiments, the execution controller receives, through the server, a control message issued by the command controller through a message queue telemetry transmission protocol, and controls the device corresponding to the execution controller according to the control message, including:

[0083] The execution controller parses the control message and obtains the parameters of the control message;

[0084] The execution controller verifies the integrity, timeliness and rationality of the control message based on the parameters of the control message and the preset rules;

[0085] In response to the control message passing the verification, obtaining a control mode, a controller type, a device number, and a control content, where the controller type includes a first controller and a second controller, and the control mode includes single-device control and multi-device control;

[0086] In response to the control mode being single device control, the controller determines the control object according to the device code;

[0087] In response to the control mode being multi-device control, the execution controller determines a control object according to a controller type, wherein the control object includes at least one controller;

[0088] The control object controls the corresponding device according to the control content and generates the execution result;

[0089] By controlling the processing code of the message queue telemetry transmission protocol in the object, a response message corresponding to the message queue telemetry transmission protocol is generated according to the execution result.

[0090] Here, the first controller may be a BMC, and the second controller may be an MCU.

[0091] Here, each controller stores MQTT protocol-related codes for parsing control messages.

[0092] The parameters of the control message may include parameters such as timestamp, session identifier, interface protocol version, effective time, operation type, control mode, and controller type. For example, the control message may store the above parameters through fields such as timeStamp, seqNum, protocolVersion, time, and power. The timeStamp field stores the timestamp, which is UTC time, in milliseconds, accurate to the millisecond; the seqNum field stores the session unique identifier; the protocolVersion field stores the interface protocol version; the time field stores the effective time, with 0 indicating immediate effect and values greater than 0 indicating UTC time; and the power field stores the operation type, with 0 indicating power on, 1 indicating power off, and 2 indicating restart.

[0093] The preset rules may include control message format standards, timestamp standards, and parameter range standards. For example, the integrity of the control information can be determined by verifying the legitimacy of the format, the timeliness can be determined by verifying whether the timestamp is within the permitted range, and the rationality can be determined by verifying whether the parameters are within the permitted range.

[0094] For example, the control mode and controller type can be stored through the Des field. The 0th to 2nd bits in the Des field are used to store the destination of the message (i.e., the control type), where 000 indicates that the destination is a computing unit, 1 indicates BMC, and 2 indicates a system consisting of an MCU and a sensor; the 8th bit in the Des field is used to store the control mode, where 0 indicates operating a single device and 1 indicates operating all devices.

[0095] For example, the device number may be stored in a PN field, and the PN field stores the asset information of the device.

[0096] For example, the response message may include fields such as timeStamp, seqNum, PN, and status, which are used to inform the execution controller whether the device operation was successful. The timeStamp field stores the timestamp; the seqNum field stores the unique session identifier; the PN field stores the device PN; and the status field stores the status code, with 0 indicating failure and 1 indicating success.

[0097] Specifically, all execution controllers that subscribe to the topic receive control messages, parse the control messages in each execution controller respectively, and determine whether the control message is a control message for itself. First, identify the operation type to determine whether it is for BMC or MCU. If the type is correct, proceed to the next step of judgment. If the type is wrong, end the operation and further determine whether the operation mode is multi-device control or single-device control. When the operation mode is multi-device control, execute the operation directly. When the operation mode is single-device control, read the device code to determine whether it is the device corresponding to the code. If not, end the operation. If so, execute the operation.

[0098] In this way, collaborative management of multiple types of devices can be achieved, and closed-loop verification can be achieved through response messages to ensure that instructions are delivered.

[0099] In some specific embodiments, after establishing a message queue telemetry transmission protocol connection between the controller in the client and the server, the method further includes:

[0100] Get the parameters of the message queue telemetry transport protocol connection between the controller in the client and the server, including the timeout period;

[0101] In response to not detecting data interaction within the timeout period, the controller in the client sends a probe message to the server;

[0102] When the controller in the client does not receive the reply message sent by the server, it is determined that a message queue telemetry transmission protocol connection between the controller in the client and the server is faulty.

[0103] Here, the timeout period is used to ensure that the connection between the client and the server remains active. For example, it can be set to 1.5 times the keep-alive period of the MQTT protocol.

[0104] Here, the probe message can be PINGREQ, that is, a request message sent by the client to the server to check whether the connection between the client and the server is still active; the reply message can be PINGREQ, that is, a response message from the server to the PINGREQ sent by the client to confirm that the server is still online and can communicate normally.

[0105] Specifically, if there is no data interaction between the client and the server within 1.5 times the keep-alive time, the client will send a PINGREQ to detect the server. If no PINGREQ response is received, the client will determine that the connection is disconnected.

[0106] In one embodiment, the length of the timeout period can be dynamically adjusted according to specific network conditions and application scenarios to achieve more accurate fault judgment.

[0107] In one embodiment, when the quality of service (QoS) is 1, after the client sends information to the server or the server sends information to the client, if no response is received within a preset time, fault detection is also required.

[0108] In one embodiment, when the client attempts to reconnect and fails multiple times, it is determined that there is a fault in the protocol connection.

[0109] In this way, connection failures can be discovered in time, pseudo-dead states can be avoided, and system reliability can be improved.

[0110] In some specific embodiments, after determining that a message queue telemetry transmission protocol connection between the controller in the client and the server is faulty, the method further includes:

[0111] Determine the target server based on the preset backup server address, replace the failed server with the target server, and establish a message queue telemetry transmission protocol connection between the controller in the client and the target server, where the target server is the device corresponding to the client's controller;

[0112] In response to the failed server recovering, the target server sends a recovery message to the controller in the client;

[0113] The controller in the client receives the recovery message and disconnects from the target server;

[0114] The controller in the client re-establishes the message queue telemetry transport protocol connection with the server;

[0115] The target server synchronizes the data during the server failure to the server through the message queue telemetry transmission protocol.

[0116] Here, the backup server is the device corresponding to the client's controller.

[0117] Here, the preset backup server address may include one or more fixed addresses. The preset backup server address may be pre-configured in the server. After receiving the preset backup server address, the server sends it to the controller of the client. The controller receives and stores the preset backup server address.

[0118] In one embodiment, a backup server can be determined through a dynamic election method based on the parameters of each server and an election rule.

[0119] Specifically, according to the preset backup server address, the backup server is determined, and the connection between each controller in the client and the original server is disconnected. Each controller in the client establishes an MQTT protocol connection with the backup server according to the preset backup server address; when the faulty original server is restored, the backup server sends a message broadcast to all clients to notify the client's controller that the original server has been restored. The client's controller disconnects from the backup server and establishes an MQTT protocol connection with the original server. The backup server switches to the client and establishes an MQTT protocol connection with the original server. The backup server sends the data during the original server failure to the original server to achieve data synchronization.

[0120] In one embodiment, after a server failure, the faulty part can be specifically identified by the following method: the backup server sends a power status query message to the BMC of the original server in MQTT. If the reply is that the server is in a shutdown state, an automatic startup will be issued and a log will be recorded. If the reply is that the server is in a power-on state, it is an OS system problem, and a shutdown and restart instruction will be issued, and a log and an alarm will be recorded. If the server cannot be started, hardware damage may occur, and the BMC log will be exported and the management platform log and alarm will be recorded. If no reply is received, it means that there is a problem with the overall status of the server (hardware / power supply / network problem), and a log and an alarm will be recorded.

[0121] Specifically, by detecting the connections between multiple controllers and servers, it can be determined whether the fault is in the controller or the server.

[0122] In this way, automatic fault recovery can be achieved and data consistency can be guaranteed.

[0123] In one embodiment, Figure 2 This is a flow chart of establishing a protocol connection in an embodiment of the present application. Figure 2 As shown, the process of establishing a protocol connection in the present application includes: S201: establishing a transmission control protocol connection between the client controller and the server; S202: the server sends a connection request message to the client controller; S203: the server determines whether it has received a reply message returned by the controller; if not, returns to S202; if received, executes S204: the execution controller and the command controller subscribe to each other's topics; S205: the command controller sends a control message; S206: the execution controller determines whether it has received the control message; if not, returns to S205; if received, the execution controller returns the execution result.

[0124] In one embodiment, Figure 3 This is a flow chart of the controller sending a control message in an embodiment of the present application, such as Figure 3 As shown, the process of the controller sending control messages in this application includes: the client MCU subscribes to the topic of the client BMC1; the client BMC1 sends a command to the MCU; the server forwards the command from the BMC to the MCU, the client MCU receives the forwarded command, parses the command, and determines whether it is a command sent to itself. If so, the command is executed, and after execution, the execution result is returned to the BMC (for example, returning the sensor reading or whether the cabinet unlocking is successful).

[0125] In one embodiment, Figure 4 This is a flow chart of the process of the server sending a control message in an embodiment of the present application, such as Figure 4 As shown, the process of the server sending control messages in this application includes: the client and the management platform (i.e., the server) establish an MQTT protocol connection and subscribe to the topic; the management platform sends a control message (for example, the server will publish a message with / BMC / power as the topic, and this message will be received by all BMC clients that have subscribed to this topic); the client parses the message (for example, parses it in the MQTT protocol related code); executes and returns the execution result (for example, returns an Errorcode); parses the execution result into the corresponding MQTT response (for example, parses it through the MQTT processing code); and sends the MQTT response result to the management platform.
