Description

Technical Field

[0001] This invention belongs to the field of data interaction technology, and in particular relates to an Internet of Things gateway access device and its data interaction method. Background Technology

[0002] With the maturation and development of the Internet of Things (IoT), device connectivity has become an inevitable trend in future technological development. Currently, a large number of IoT devices, such as wearable devices (e.g., smart bracelets), implantable devices (e.g., pacemakers), and smart home devices (e.g., central air conditioning), are widely used in users' daily lives, and all of these devices are connected to the IoT.

[0003] However, different types of devices have different communication requirements. For example, some entertainment-oriented devices require high-speed and low-latency communication networks, while wearable devices are used to sense non-human safety data (body temperature, walking speed, etc.) and have no specific requirements for communication speed and latency. Even low-speed and high-latency communication networks can meet the needs of wearable devices. Implantable devices and everyday smart home devices do not have high requirements for communication speed but have high requirements for latency and need low latency. However, for implantable devices, continuous communication is more necessary than for everyday smart home devices. Therefore, the processing of device data, the configuration of each device, and other aspects are different, and the needs of different devices are also different.

[0004] As users own more and more devices, a solution is needed to better manage these devices and prevent important and high-priority device transmissions from being affected by other devices occupying transmissions. Summary of the Invention

[0005] The purpose of this invention is to provide an Internet of Things (IoT) gateway access device and its data interaction method, aiming to solve the problems of inaccurate network security protection and poor user experience caused by the inability of existing technologies to provide an effective method for network security protection of IoT systems.

[0006] On one hand, the present invention provides an Internet of Things (IoT) gateway access device, comprising:

[0007] The security level module is used to establish a transmission level system, which divides multiple transmission levels according to the type of IoT device. The transmission levels include, but are not limited to, the first transmission level, the second transmission level, and the third transmission level.

[0008] The speed limiting module is used to preset multiple transmission speed limits based on the transmission level, and to set corresponding transmission speed limits for each transmission level. The first transmission level has the maximum transmission speed limit, and the transmission speed of subsequent transmission levels decreases step by step.

[0009] The identification module is used to obtain the IoT device type corresponding to the connected devices in the IoT, and assign the corresponding transmission level according to the IoT device type of the connected devices.

[0010] The determination module is used to determine and count the number of access devices in each transmission level after a preset time period.

[0011] The speed-up module is used to upgrade the next level of transmission when the number of access devices in any transmission level is zero. The upgrade process is to adjust the upper limit of the transmission speed of the next level of transmission to the transmission speed of the current transmission level.

[0012] The reset module is used to assign a flag to a transmission level and reset the transmission speed limit of the next lower transmission level to a preset value when the number of access devices in the marked transmission level is not zero.

[0013] The tagging module is used to assign a tag to the transmission level when upgrading the next level of transmission level, and to remove the tag from the transmission level when resetting the transmission speed limit of the next level of transmission level to a preset value.

[0014] Preferably, the device further includes a log module, used to generate a system log each time a transmission level is assigned or removed as a flag to record the transmission level speed-up or reset operation.

[0015] On the other hand, the present invention also provides a data interaction method for an Internet of Things gateway, the method comprising the following steps:

[0016] S1: Establish a transmission level system, and divide multiple transmission levels according to the type of IoT device. The transmission levels include, but are not limited to, the first transmission level, the second transmission level, and the third transmission level.

[0017] S2: Preset multiple transmission speed limits based on transmission level, and set corresponding transmission speed limits for each transmission level, where the first transmission level has the maximum transmission speed limit, and the transmission speed of subsequent transmission levels decreases step by step.

[0018] S3: Obtain the IoT device type corresponding to the connected device in the IoT, and assign the corresponding transmission level according to the IoT device type of the connected device;

[0019] S4: After a preset time, the number of access devices in each transmission level is judged and counted. When the number of access devices in any transmission level is zero, the next level of transmission level is upgraded. The upgrade process is to adjust the upper limit of the transmission speed of the next level of transmission level to the transmission speed of the current transmission level, and at the same time, a mark is assigned to the transmission level.

[0020] S5: When it is determined that the number of access devices in the marked transmission level is not zero, reset the transmission speed limit of the next level of transmission level to the preset value and remove the mark.

[0021] Preferably, the preset time is 10 seconds.

[0022] Preferably, in the above steps, each time a transmission level is assigned or removed a flag, a system log is generated to record the transmission level acceleration or reset operation.

[0023] Preferably, the IoT device type is classified by IoT device information, which includes manufacturer, model, serial number, operating system, list of open ports, and device account information.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention presets the transmission level of IoT devices based on their type. By combining the IoT device type with the communication transmission priority of that type of IoT device, it sets the upper limit of the transmission speed for that type of IoT device, realizing a tiered transmission speed division. This speed limiting method ensures that low-occupancy devices can continue to communicate, while higher-priority devices, due to their higher transmission speed upper limit, can occupy lower-priority transmissions. At the same time, limiting the transmission speed can prevent high-bandwidth, entertainment-oriented devices from excessively occupying communication. When no device is connected to a certain transmission level, the transmission restriction is automatically lifted for devices in the next lower transmission level, thereby improving the user experience.
