[0038] When managing the access of IoT gateway devices, if the communication protocol of an IoT device connected to an IoT gateway device is relatively complex, it will inevitably lead to poor elasticity of the IoT.

[0039] Elastic defect gateway device: It is determined based on the number of devices connected to the Internet of Things. Specifically, the Internet of Things gateway devices with a number of devices greater than the preset number are used as elastic defect gateway devices.

[0040] Devices to be optimized: The communication protocol with the connected IoT devices is regarded as the protocol deviation device. The device deviation coefficient of the connected IoT devices is determined by the proportion of the number of protocol deviation devices in the connected IoT devices of the elastic defect gateway device. The connected IoT devices with a device deviation coefficient greater than 0.6 are regarded as devices to be optimized.

[0041] Matching access gateway devices: A candidate device whose access number of IoT devices is less than a preset access number is used as a matching access gateway device for the device to be optimized.

When the data volume of the communication data of the elastic defective gateway device is not greater than the preset data volume, it is not necessary to perform elastic access control on the device to be optimized;

[0043] When the amount of communication data of the elastic defect gateway device is greater than the preset amount of data:

[0044] Whether elastic access control needs to be performed on the device to be optimized is determined based on the data volume of the communication data of the matching access gateway device and the data volume of the communication data of the elastic defective gateway device.

[0051] Specifically, the access type of the IoT device includes real-time communication, periodic communication and control communication.

[0052] It should be noted that the control communication is to control the accessed IoT device to send communication data when the accessed IoT device receives a control signal.

[0057] Furthermore, the data processing complexity coefficient of the device group is determined according to the weight sum of preset complexity coefficients corresponding to the access Internet of Things devices of different access types of the device group.

[0058] It should also be noted that determining whether the IoT gateway device is an elastic defect gateway device according to the data processing complexity coefficient of different device groups specifically includes:

[0059] The complex processing device groups in the device group are determined by using data processing complexity coefficients of different device groups, and whether the Internet of Things gateway device is an elastic defect gateway device is determined according to the number of complex processing device groups.

[0060] Optionally, the method for determining the elasticity-deficient gateway device in the Internet of Things gateway device is:

[0065] Optionally, the above step S11 includes the following contents:

[0066] S111 determines the number of access IoT devices of different access types in the IoT gateway device using access IoT devices of different access types. When the number of access IoT devices in the IoT gateway device is greater than the preset number of IoT devices, the IoT gateway device is determined to be an elastic defect gateway device. When the number of access IoT devices in the IoT gateway device is not greater than the preset number of IoT devices, the process proceeds to step S112.

[0068] S113 obtains the number of access IoT devices of different access types. When the number of access IoT devices of the preset access type does not meet the requirement, the IoT gateway device is determined to be an elastic defect gateway device. When the number of access IoT devices of the preset access type meets the requirement, the process proceeds to step S114.

[0069] S114 determines the basic processing complexity coefficient of the Internet of Things gateway device according to the number of accessed Internet of Things devices of different access types. When the basic processing complexity coefficient of the Internet of Things gateway device does not meet the requirements, the Internet of Things gateway device is determined to be an elastic defect gateway device. When the basic processing complexity coefficient of the Internet of Things gateway device does not meet the requirements, proceed to step S12.

When the number of device groups is not greater than the preset number of groups, it is determined that the IoT gateway device does not belong to the elastic defect gateway device.

[0073] S122 determines the data processing complexity coefficients of different device groups according to the number of connected IoT devices in different device groups and the access types of different connected IoT devices. When there is a device group whose data processing complexity coefficient does not meet the requirements, the process proceeds to step S123. When there is no device group whose data processing complexity coefficient does not meet the requirements, the process proceeds to step S13.

[0074] S123: The device group whose data processing complexity coefficient does not meet the requirement is regarded as a complex device group. When the number of complex device groups does not meet the requirement, it is determined that the IoT gateway device belongs to an elastic defective gateway device. When the number of complex device groups meets the requirement, the process proceeds to step S124.

[0121] S212: the device group corresponding to the connected IoT device is used as the matching device group. When the number ratio of the matching device group is within the preset number ratio interval, the process proceeds to step S213. When the number ratio of the matching device group is not within the preset number ratio interval, the process proceeds to step S214.
