[0032] The master-slave device communication method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, the master device 102 communicates with the slave device 104. The controller of the master device 102 is configured with a management module 1022 and a control module 1024. The management module 1022 sends a message instruction to the slave device 104, receives device information returned by the slave device 104 according to the message instruction, and establishes a management channel between the master device 102 and the slave device 104 when the device information is verified; the management channel is a data transmission channel based on the first message transmission protocol, which is used to transmit management configuration data between the master device 102 and the slave device 104; a request to subscribe to configuration information is sent to the slave device 104 through the management channel; the request to subscribe to configuration information is used to specify that the slave device 104 subscribes to the target request sent by the master device 102; the target request includes at least a control channel connection response request; the control channel connection request sent by the slave device 104 is received through the control module 1024, and a control channel connection response request is sent to the slave device 104 to establish a control channel between the master device 102 and the slave device 104; the control channel is a data transmission channel based on the second message transmission protocol, which is used to transmit real-time network indicators between the master device 102 and the slave device 104.

[0033] In one embodiment, Figure 2 As shown, a master-slave device communication method is provided. This embodiment uses this method to Figure 1 Taking the master device 102 in FIG. 1 as an example, the method includes the following steps:

[0034] S210, sending a message instruction to the slave device through the management module, receiving the device information returned by the slave device according to the message instruction, and establishing a management channel between the master device and the slave device when the device information passes the verification; the management channel is a data transmission channel based on the first message transmission protocol, which is used to transmit management configuration data between the master device and the slave device.

[0035] The master device can be a master gateway (master optical modem), which is used to directly connect to the operator's fiber-to-the-home line. The slave device can be a slave gateway (slave optical modem), which is connected to the master device via optical fiber and is used to extend the network to other areas (such as conference rooms, offices, etc.).

[0036] The controller is a hardware device used to manage and control slave devices, including but not limited to microprocessors, central processing units, and system-on-chips. The management module is a logical processing module configured within the controller, responsible for configuration management, data reporting, and alarms. The control module is a logical processing module configured within the controller, responsible for user permissions, user resource management, and user roaming management.

[0037] The message command is used to request the device to return device information. Specifically, the message command can be an OMCI (Optical Network Management and Control Interface) message. Device information includes, but is not limited to, the device's MAC (Media Access Control Address), LOID (Local IDentifer), and SN (Serial Number).

[0038] The first message transmission protocol is a lightweight, open message transmission protocol commonly used for inter-device communication in IoT applications. Specifically, the first message transmission protocol may be MQTT (Message Queuing Telemetry Transport).

[0039] The management configuration data is used to configure and manage the slave device, including but not limited to the WIFI name, WIFI password, WIFI SSID (Service Set Identifier), and channel settings of the slave device.

[0040] In an embodiment of the present application, when a slave device accesses a fiber optic network, the master device sends a CONNECT packet to the slave device, which responds with a CONNACK packet, establishing an MQTT connection between the master and slave devices. The master device sends a message instruction to the slave device via the management module. The slave device parses the message instruction, obtains its own device information, and sends this information to the master device. Specifically, the device information includes the slave device's MAC address and LOID code, or the slave device's MAC address and SN code.

[0041] The master device stores a pre-set device whitelist containing information about each device. Specifically, this information includes the device's MAC address and LOID code, or the device's MAC address and SN code. The master device matches the received device information with the whitelist. If the device information matches the information stored in the whitelist, the master device determines that the device information returned by the slave device has been verified and establishes a management channel between the master and slave devices.

[0042] In one embodiment, when the device information is inconsistent with the device information stored in the device whitelist, it is determined that the device information returned by the slave device fails verification, and the management channel between the master device and the slave device is not established.

[0043] S220, sending subscription request configuration information to the slave device through the management channel; the subscription request configuration information is used to specify the slave device to subscribe to the target request sent by the master device; the target request at least includes a control channel connection response request.

[0044] The MQTT protocol's publish-subscribe mechanism involves publishers (master or slave devices) sending messages to one or more topics on a proxy service. Subscribers (slave or master devices) subscribe to messages from the proxy service on one or more topics. The proxy service forwards messages to ensure that each subscriber receives the messages they are interested in. The proxy service can be integrated with the master device.

[0045] The subscription configuration information requested includes but is not limited to the subscription request type and request content.

[0046] The control channel connection response request is a response request returned by the master device based on the control channel connection request issued by the slave device.

[0047] In an embodiment of the present application, after establishing a management channel between the master and slave devices, it is also necessary to establish a control channel between the master and slave devices. Since the management channel and the control channel share a proxy service, and only the management channel is allowed to transmit management configuration data, and only the control channel is allowed to transmit real-time network indicators, it is necessary to convert the publish-subscribe mechanism of the control channel based on the management channel.

[0048] Specifically, the subscription request configuration information is sent to the slave device through the management channel, the slave device parses the subscription request configuration information, and subscribes to the target request to the proxy service.

[0049] S230, receiving a control channel connection request sent by the slave device through the control module, and sending a control channel connection response request to the slave device to establish a control channel between the master device and the slave device; the control channel is a data transmission channel based on the second message transmission protocol, which is used to transmit real-time network indicators between the master device and the slave device.

[0050] The second message transmission protocol is an extended protocol of the second message transmission protocol and is specially designed for sensor networks.

[0051] The real-time network indicators include, but are not limited to, device status data of slave devices, authority management data of the master device over the slave devices, and resource allocation data.

[0052] In an embodiment of the present application, the master device subscribes to the control channel connection request. When the slave device publishes the channel connection request to the proxy service, the proxy service forwards the control channel connection request to the master device.

[0053] The slave device subscribes to the control channel connection response request, the master device sends the control channel connection response request to the proxy service, and the proxy service forwards the control channel connection response request to the slave device to establish a control channel between the master device and the slave device.

[0054] In order to better understand steps S210 to S230, Figure 3 Figure 2 shows a system architecture diagram of a master-slave device communication method. The master device includes a master bus, an agent, and a controller. The master bus serves as the data exchange channel within the master device, connecting the agent and controller within the master device. The master agent interacts with the master bus to handle data forwarding, protocol conversion, and management tasks. The controller is the control core of the master device, responsible for decision-making and scheduling, and directly connects to the slave bus to manage the slave devices. The controller includes a management module and a control module. The slave device includes a slave bus and an agent. The slave bus serves as the data channel within the slave device, connecting the agent within the slave device. The slave agent interacts with the slave bus, receiving commands from the master and returning data. The master controller directly connects to the slave bus, enabling the master to control the slave device. The master agent and the slave agent do not communicate directly, but instead interact with the controller via the master / slave bus.

[0055] like Figure 4As shown, a sequential flow chart of a master-slave device communication method is provided. The master device's controller establishes MQTT connections with the master bus, the master bus with the slave bus, and the slave bus with the slave agent. The master and slave devices define a management interface L1 and a control interface L2. The master device's controller and the slave agent register and go online through the L1 interface for a management channel. The specific process is described in step S210 above. After establishing the management channel, the master device's controller subscribes to inquiries sent by the slave device to the master and responses from the slave device to the master's requests. Inquiries include control channel connection requests. The slave device's agent subscribes to queries sent by the master to the slave device and replies from the master to the slave device. Replies include control channel connection response requests, thereby implementing a publish-subscribe mechanism conversion for the control channel. The specific process is described in step S220 above. The master device's controller initiates the control channel through the L1 interface. Specifically, this triggers the slave device's agent to issue a control channel connection request. The Controller of the master device and the Agent of the slave device establish a control channel connection through the L2 interface. For details, refer to the above step S230. After the control channel is established, the Controller of the master device and the Agent of the slave device control network indicators to interact normally through the L2 interface.

[0056] The above-mentioned master-slave device communication method sends a message instruction to the slave device through the management module, receives the device information returned by the slave device according to the message instruction, and establishes a management channel between the master device and the slave device when the device information passes the verification; the management channel is a data transmission channel based on the first message transmission protocol, which is used to transmit management configuration data between the master device and the slave device; sends a request to subscribe to configuration information to the slave device through the management channel; the request to subscribe to configuration information is used to specify the slave device to subscribe to the target request sent by the master device; the target request at least includes a control channel connection response request; receives the control channel connection request sent by the slave device through the control module, and sends a control channel connection response request to the slave device to establish a control channel between the master device and the slave device; the control channel is a data transmission channel based on the second message transmission protocol, which is used to transmit real-time network indicators between the master device and the slave device. According to the above content, this application is based on the first message transmission protocol, and the management module of the master device establishes a management channel with the slave device, and the management configuration data is transmitted through the management channel; based on the second message transmission protocol, the control module of the master device establishes a control channel with the slave device, and the real-time network indicators are transmitted through the control channel; since the management channel and the control channel are independent of each other, the management configuration data and real-time network indicators between the master and slave devices are distinguished, realizing decoupled communication between data, thereby improving data communication efficiency.

[0057] In one embodiment, the data transmission reliability of the first message transmission protocol is greater than the data transmission reliability of the second message transmission protocol, and the data transmission delay of the first message transmission protocol is greater than the data transmission delay of the second message transmission protocol.

[0058] In the embodiment of the present application, since the management module implements core functions such as configuration management, data reporting and alarm, the first message transmission protocol is adopted to ensure high reliability of data transmission in the management channel.

[0059] Since the control module implements real-time business functions such as user authority management, resource allocation and roaming control, the second message transmission protocol is adopted to ensure low latency in data transmission through the control channel.

[0060] In one embodiment, the first message transmission protocol is the MQTT protocol based on TCP / IP.

[0061] Among them, the MQTT protocol based on TCP / IP can provide reliable, orderly and error-free data transmission.

[0062] In one embodiment, the second message transmission protocol is the MQTT-SN protocol based on UDP / IP.

[0063] Among them, the UDP / IP-based MQTT-SN protocol is lighter than TCP and is suitable for resource-constrained devices or scenarios requiring low latency, but it does not provide reliability guarantees (such as packet retransmission).

[0064] In one embodiment, before the step of receiving, by the control module, a control channel connection request sent from the device, step S201 is included, specifically as follows:

[0065] S201, sending a control channel connection start request to the slave device through the management channel; the start request is used to trigger the slave device to send a control channel connection request to the control module.

[0066] In an embodiment of the present application, the master device sends a startup request for the control channel connection to the slave device through the management channel. The slave device parses the startup request for the control channel connection, generates a control channel connection request, and sends the control channel connection request to the master device for subsequent control channel connection online.

[0067] The embodiment of the present application can flexibly control the establishment of a control channel between a master and a slave device by sending a start request for a control channel connection.

[0068] In one embodiment, the master-slave device communication method further includes steps S240 to S250, which are specifically as follows:

[0069] S240: Sending management configuration data to the slave device through the management channel, and receiving the management configuration data execution result returned by the slave device; and / or,

[0070] In an embodiment of the present application, taking the management configuration data as a WIFI name as an example, the user modifies the WIFI name of the slave device on the master device, the master device sends the modified WIFI name to the slave device, the slave device updates the WIFI name, and feeds back the updated result of the WIFI name to the master device.

[0071] S250: Receive device status data reported by the device through the management channel.

[0072] The device status data includes but is not limited to the signal strength, online and offline status, and number of online devices from the device.

[0073] In the embodiment of the present application, the slave device periodically reports device status data, the master device receives the device status data, and stores the device status data in a database.

[0074] In the embodiment of the present application, the master and slave devices can realize convenient communication of management configuration data and device status data based on the management channel.

[0075] In one embodiment, after the step of receiving the device status data reported by the slave device through the management channel, steps S252 to S254 are further included, specifically as follows:

[0076] S252: Analyze and process the device status data through the management module to obtain the device status of the slave device.

[0077] The device status includes normal status and abnormal status.

[0078] In the embodiment of the present application, if the signal strength of the device is less than a preset signal strength threshold, the device state is determined to be abnormal. If the signal strength of the device is greater than or equal to the preset signal strength threshold, the device state is determined to be normal.

[0079] S254: When it is detected that the device status of the slave device is abnormal, an alarm signal is issued through the management module.

[0080] In an embodiment of the present application, the management module pushes an alarm signal to the operation and maintenance APP to remind the operation and maintenance personnel of the abnormality of the slave device and to clean up the abnormality of the slave device in time.

[0081] It should be understood that, although the various steps in the flowcharts involved in the above embodiments are displayed in sequence according to the instructions of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of the steps or stages in other steps or other steps. It is understandable that the various steps in different embodiments can be freely combined as needed, and the various non-contradictory schemes formed by the combination all fall within the scope of protection of this application.
