Description

Technical Field

[0001] This invention relates to the technical field of Internet of Things (IoT) data processing, and in particular to a method and system for centralized message processing based on the Internet of Things. Background Technology

[0002] The Internet of Things (IoT) typically consists of an IoT platform, several IoT terminals, and several IoT sensors. IoT sensors, as the bottom-level units of the IoT, are used for sensing and detecting external data. IoT terminals, as the middle units, collect the detection data generated by the IoT sensors and control them to perform corresponding sensing operations. The IoT platform, as the highest-level unit, manages all IoT terminals and sensors uniformly. During operation, IoT terminals can be switched and connected at any time to meet the control needs of different IoT terminals on IoT sensors. Current IoT systems use gateway configurations to connect IoT terminals and IoT sensors, which cannot quickly and in real-time switch control between different IoT terminals and different IoT sensors, reducing the operational stability within the IoT system. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a centralized message processing method and system based on the Internet of Things (IoT). The method broadcasts connection invitation commands to external devices based on the real-time connection status of IoT terminals on the IoT platform. It allocates IoT connection permissions based on the response messages from external terminals to the connection invitation commands. It analyzes the service message data of terminals connected to the IoT, generates service commands, classifies these commands, and obtains a service command queue corresponding to IoT sensors. Based on the operating status of the IoT sensors, it sequentially sends the service commands contained within the service commands to the IoT sensors. By broadcasting connection invitations, it allocates IoT connection permissions to responding external terminals and selects appropriate service commands based on the terminal's service message data, sending them to the IoT sensors. This enables different terminals to control the connection to IoT sensors, improving the operational stability within the IoT ecosystem.

[0004] This invention provides a centralized message processing method based on the Internet of Things, comprising the following steps:

[0006] Step S2: When a terminal outside the Internet of Things (IoT) connects to the IoT, the service message data of the terminal is analyzed and processed to generate service instructions corresponding to the service message data; the service instructions are classified to obtain a service instruction queue corresponding to the IoT sensors inside the IoT.

[0007] Step S3: Based on the working status of the IoT sensors within the IoT, the business instructions contained in the business instruction queue are sequentially sent to the IoT sensors.

[0008] Furthermore, in step S1, based on the real-time connection status of the IoT terminals on the IoT platform, a connection invitation command is broadcast and sent externally, including:

[0010] If the computational load of the task is less than the maximum allowed computational load, a connection invitation command is broadcast to the outside world.

[0011] Further, in step S1, based on the response message from the terminal outside the Internet of Things (IoT) to the connection invitation command, IoT connection permissions are assigned to the corresponding terminal outside the IoT, including:

[0014] If the identity information does not exist in the preset terminal identity information whitelist, then the IoT connection key will not be assigned to the corresponding terminal outside the IoT.

[0015] Further, in step S2, after a terminal outside the Internet of Things (IoT) connects to the IoT, the service message data of the terminal is analyzed and processed to generate service instructions corresponding to the service message data; the service instructions are classified to obtain a service instruction queue corresponding to the IoT sensors inside the IoT, including:

[0031] If the identity information does not exist in the preset terminal identity information whitelist, then the IoT connection key will not be assigned to the corresponding terminal outside the IoT.

[0032] Furthermore, the service instruction generation module is used to analyze and process the service message data of a terminal outside the Internet of Things (IoT) after the terminal connects to the IoT, and generate service instructions corresponding to the service message data; classify the service instructions to obtain a service instruction queue corresponding to IoT sensors inside the IoT, including:
