Description

Technical Field

[0001] This invention relates to the technical field of Internet of Things (IoT) control, and in particular to a method and system for managing the interaction of terminal devices based on IoT. Background Technology

[0002] The Internet of Things (IoT) typically consists of an IoT platform and several IoT terminal devices. Each IoT terminal device connects to the IoT platform and operates independently, uploading the data generated during its operation to the IoT platform. Furthermore, each IoT terminal device can interact with external terminal devices to improve its performance. However, during these interactions, the external terminal devices gain access to the IoT, which can impact the data security within the IoT ecosystem. It is also difficult to fully and accurately control and regulate the operations of external terminal devices within the IoT. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a terminal device interaction management method and system based on the Internet of Things (IoT). When an external terminal device has permission to access the IoT, it determines whether the IoT terminal device meets preset connection conditions based on the working status information of the IoT terminal device it needs to connect to. This instructs the IoT platform to return a time-sensitive key to the external terminal device. Furthermore, when an external terminal device sends a time-sensitive key to the IoT terminal device, the system adjusts the connection status of the IoT terminal device within the IoT. After identifying the external terminal device requesting connection to the IoT, it assigns a time-sensitive key to the external terminal device, thereby controlling the time when the external terminal device accesses the IoT. This ensures that the IoT terminal device only connects to external terminal devices when it is idle. Simultaneously, after the IoT terminal device connects to an external terminal device, it adapts the connection status of the IoT terminal device within the IoT to prevent interference from external terminal devices and ensure the data security of the IoT.

[0019] If the required time is less than or equal to a preset time threshold, then the IoT terminal device is determined to meet the preset connection conditions; otherwise, the IoT terminal device is determined not to meet the preset connection conditions.

[0020] When the preset connection conditions are met, the IoT platform is instructed to generate a time-sensitive key according to the required time and return the key to the external terminal device; wherein the key is converted to a valid state only after a period of time not less than the required time.

[0021] Furthermore, in step S3, when the external terminal device sends the time-sensitive key to the IoT terminal device, the connection status of the IoT terminal device within the IoT is adjusted, including:

[0054] The beneficial effects of the above technical solution are as follows: When an external terminal device has the permission to access the Internet of Things (IoT), the IoT-based terminal device interaction management method determines whether the IoT terminal device meets the preset connection conditions based on the working status information of the IoT terminal device it needs to connect to, thereby instructing the IoT platform to return a time-sensitive key to the external terminal device; and when the external terminal device sends a time-sensitive key to the IoT terminal device, the connection status of the IoT terminal device within the IoT is adjusted. After identifying the external terminal device requesting to connect to the IoT, the method allocates a time-sensitive key to the external terminal device, thereby controlling the time when the external terminal device accesses the IoT, ensuring that the IoT terminal device only connects to the external terminal device when it is in an idle state; at the same time, after the IoT terminal device connects with the external terminal device, the method adapts the connection status of the IoT terminal device within the IoT, avoiding interference from the external terminal device to the IoT and ensuring the data security of the IoT.

[0055] Preferably, in step S1, the connection request from the external terminal device is analyzed and processed to determine whether the external terminal device has connection permission, including:

[0056] From the connection request from the external terminal device, the device identity information of the external terminal device is extracted, and the device identity information is compared with the whitelist of allowed connection devices of the Internet of Things platform;

[0057] If the device's identity information exists in the whitelist of allowed connected devices, then it is determined that the external terminal device has permission to connect to the Internet of Things.

[0058] If the device's identity information is not present in the whitelist of allowed connected devices, then it is determined that the external terminal device does not have permission to connect to the Internet of Things.

[0059] The beneficial effects of the above technical solution are as follows: When an external terminal device needs to connect to the Internet of Things (IoT) and link with one of the IoT terminal devices, it first sends a connection request. The device identity information of the external terminal device is extracted from the connection request, and then compared with a whitelist of allowed connection devices. This method ensures that only designated external terminal devices can obtain access to the IoT, thereby preventing unauthorized connections from external terminal devices to the IoT.
