[0001] The present invention relates to a method for switching modes of an Internet of Things terminal, and belongs to the technical field of Internet of Things configuration methods. Background Art

[0002] Traditional industrial sensor systems mostly adopt fixed modes (such as serving only as gateways or nodes), which have the following problems: 1. Poor deployment flexibility: Single-mode devices cannot adapt to complex network topology requirements, requiring additional configuration of different devices, increasing costs.

[0003] 2. Insufficient scalability: Fixed-mode devices cannot dynamically adjust their roles and are difficult to adapt to changes in network size.

[0004] 3. Complex maintenance: The mode needs to be adjusted through dedicated software or hardware, which is cumbersome to operate.

[0005] In the prior art, although dual-mode communication devices exist, mode switching relies on external tools or fixed configurations, and dynamic and user-friendly switching cannot be achieved. Summary of the Invention

[0017] A method for switching an IoT terminal mode, comprising the following steps: (1) Device initialization: When the IoT terminal device is started, it reads the configuration information and determines its basic parameters and functional modules; (2) Mode selection: select the device's operating mode, including gateway mode and node mode, based on preset rules or user input; (3) Mode configuration: configure the device’s network parameters, communication protocols, and data processing logic accordingly based on the selected working mode; (4) Mode switching: During device operation, the device dynamically switches between gateway mode and node mode according to the actual network environment and application requirements; (5) Data transmission: In gateway mode, the device acts as a data aggregation and forwarding center, receiving data from node devices and sending it to the server; in node mode, the device acts as a data collection and upload terminal, collecting sensor data and sending it to the gateway device.

[0018] In step (1), device initialization includes hardware initialization, network initialization and sensor initialization.

[0019] In step (2), the mode selection is achieved by reading a configuration file or an instruction input by the user.

[0020] In step (3), the mode configuration includes the configuration of the LoRa module, the WiFi module and the MQTT service.

[0021] In step (4), mode switching is achieved by changing the working mode parameters of the device.

[0022] In step (5), data transmission includes LoRa communication and MQTT communication.

[0023] Based on the unique ID of each device, a QR code is generated and affixed to the surface of the device. After the user scans the code, they will jump to the built-in web page; the web page displays the device status in real time and provides mode switching options. Example

[0024] 1. Device Initialization: When the device boots up, the setup() function is called to perform hardware and network initialization. For example, it initializes the LoRa module, WiFi module, and sensor module. Configuration information is read to determine the device's basic parameters and functional modules. This configuration information can be stored in the device's non-volatile memory or retrieved from a server over the network.

[0025] 2. Mode Selection: The user selects GATEWAY or NODE in the "MODE SELECTION" function block to determine the device's operating mode. After saving, the mode is stored in the Web_Data array in the system configuration file. When the device is subsequently restarted and initialized, it reads the data in the configuration file and uses the Web_Data value to determine whether the device is operating as a gateway or node, automatically setting the device's mode.

[0026] 3. Mode Configuration: Based on the selected operating mode, configure the device's network parameters, communication protocol, and other parameters. For example, in gateway mode, configure the LoRa module's receiving function, LoRa.onReceive(Receive), and start the WiFi network and MQTT service. In node mode, configure the LoRa module's sending function, LoRa_Gateway_sendMessage(), and set the sensor data collection interval. Configuration parameters include, but are not limited to, the LoRa module's frequency, spreading factor, bandwidth, coding rate, and transmit power; the WiFi module's SSID, password, IP address, subnet mask, gateway address, and DNS address; and the MQTT service's proxy address, client ID, username, password, port number, publish topic, and subscribe topic.

[0027] 4. Mode switching: During device operation, the device can switch between gateway mode and node mode according to the actual network environment and application requirements. For example, the mode switching logic is triggered by the change of the value of Web_Data

[31] [1]. When switching modes, the device will reconfigure the network parameters and communication protocols to ensure normal operation in the new working mode. For example, when switching from gateway mode to node mode, the device will shut down the WiFi network and MQTT service, start the sending function of the LoRa module, and set the interval for sensor data collection.

[0028] 5. Data Transmission: In gateway mode, the device calls the GatewayMode() function to receive data from node devices and send it to the server. Data transmission includes LoRa and MQTT communication. In node mode, the device calls the NodeMode() function to collect sensor data and send it to the gateway device. Data collection includes environmental parameters such as temperature, humidity, vibration, noise, and carbon monoxide concentration.

[0029] Each device has a unique ID, which generates a QR code and is affixed to the device surface. Users scan the code to jump to the built-in web page; The webpage displays the device status (such as IP, sensor values) in real time and provides mode switching options.

[0030] The present invention can dynamically switch between the gateway mode and the node mode according to the actual network environment and application requirements during the operation of the device, thereby improving the flexibility and adaptability of the device.

[0031] In some simple scenarios, there is no need to deploy dedicated node devices, which reduces hardware investment in data collection and lowers costs.

[0032] Through the web interface, users can easily configure the device's operating mode and network parameters, improving device usability and maintainability.
