Description

Technical Field

[0001] This invention relates to the field of smart homes, and more particularly to a smart home wireless communication routing system. Background Technology

[0002] Smart home refers to using more advanced technologies to improve the convenience of life. In home life, broadband networks have become an indispensable tool. Bandwidth networks have many applications, including indicating the data transmission capacity of signal transmissions, the amount of data passing through a link per unit time, and the display capacity of a monitor. 1. In analog signal systems, bandwidth refers to the amount of data that can be transmitted in a fixed amount of time, that is, the data transmission capacity in a transmission channel. It is usually expressed in cycles per second or Hertz. 2. In digital devices, bandwidth refers to the amount of data that can pass through a link per unit time. It is usually expressed in bps, that is, the number of bits that can be transmitted per second.

[0003] The published invention CN117294646A discloses an SDN cross-domain intelligent routing method based on multi-agent deep reinforcement learning. Targeting the hierarchical architecture of large-scale SDN networks, it divides the network into multiple subdomains and assigns an agent to each subdomain. Distributed technology is used to perform concurrent learning of the SDN multi-agents, reducing model training time overhead. Agents in the local controller and root controller adaptively generate optimal intra-domain and inter-domain routing paths in real time under the current network conditions. This effectively solves problems such as traffic packet accumulation and network congestion in SDN cross-domain routing due to the inflexibility of traditional routing algorithms in data forwarding, and achieves real-time intelligent optimization of optimal routing decisions in large-scale networks. For intelligent routing devices, it is necessary to maximize power saving and reduce power consumption to improve functionality. For example, when there are registered devices around the intelligent routing device, the download bandwidth should be automatically enabled and adjusted to the minimum value; when there are no registered devices around the intelligent routing device, the download bandwidth should be automatically disabled. Clearly, existing technologies lack corresponding solutions. Summary of the Invention

[0004] To address the technical problems in the prior art, the present invention provides a smart home wireless communication routing system, the system comprising:

[0005] A bandwidth adjustment mechanism, located within the smart router, is used to enable and adjust the download bandwidth of the smart router to the minimum bandwidth value when a signal indicating the presence of a registered device is received, and to disable the download bandwidth of the smart router when a signal indicating the absence of a registered device is received.

[0006] A content capture mechanism is installed at the front end of the smart router device to perform screen content capture actions on the surrounding environment of the smart router device, so as to obtain and output the corresponding surrounding environment screen.

[0007] A sharpening processing device, installed inside a smart router and connected to the content capture mechanism, is used to perform sharpening processing based on a USM filter on the received surrounding environment image to obtain and output a corresponding real-time sharpened image.

[0008] A smoothing processing device, connected to the sharpening processing device, is used to perform scaling-free transformation blurring processing on the received instant sharpened image to obtain and output the corresponding smoothed image.

[0009] A band-stop filter device, connected to the smoothing processing device, is used to perform band-stop filtering processing on the received smoothed image to obtain and output a corresponding band-stop filtered image.

[0010] A signal conversion device, installed within the intelligent router and connected to both the bandwidth adjustment mechanism and the band-stop filter, is used to select the image region in the received band-stop filtered image that best matches the contour standard image corresponding to the registered network device of the intelligent router and whose number of pixels in the band-stop filtered image exceeds or equals a set limit as the current reference region. Within the current reference region, each target pixel is identified according to a preset target brightness value range. The target pixels in the current reference region are then combined after removing isolated pixels to obtain a target image block to be determined. When the area ratio of the target image block to the band-stop filtered image is greater than or equal to a preset ratio threshold, a registered device presence signal is issued.

[0011] The signal conversion device is further configured to issue a registration device non-existent signal when the area ratio of the target image block to the band-stop filtered image is less than the preset ratio threshold.

[0012] By implementing this invention, the image region in the band-stop filtered image obtained after customized enhancement processing of the surrounding environment image corresponding to the smart router device, which best matches the outline standard image corresponding to the registered network device of the smart router device and occupies more than or equal to a set number of pixels in the band-stop filtered image, can be used as the current reference region. Each target pixel in the current reference region is identified according to a preset target brightness value range. The target pixels in the current reference region are combined after removing isolated pixels to obtain a target image block to be determined. When the area ratio of the target image block to the band-stop filtered image is greater than or equal to a preset ratio threshold, a registered device presence signal is issued; otherwise, a registered device absence signal is issued. This achieves secondary confirmation of whether a registered user device exists around the smart router device. Furthermore, a bandwidth adjustment mechanism installed in the smart router device is used to turn on and adjust the download bandwidth of the smart router device to the minimum bandwidth value when a registered device presence signal is received, and to turn off the download bandwidth of the smart router device when a registered device absence signal is received. This completes intelligent management of the download bandwidth of the smart router device and avoids wasting excessive bandwidth resources. Attached Figure Description

[0053] In a smart home wireless communication routing system according to any embodiment of the present invention:

[0054] The sharpening device, the smoothing device, the band-stop filtering device, and the signal conversion device are each implemented using different CPLD chips, and the CPLD chips are designed using VHDL language.

The multiple heat dissipation holes of any one of the sharpening device, the smoothing device, the band-stop filter, and the signal conversion device are evenly distributed on their housings, including the fact that the diameter of each heat dissipation hole in any one of the multiple heat dissipation holes of the sharpening device, the smoothing device, the band-stop filter, and the signal conversion device is the same.

[0058] In addition, in the smart home wireless communication routing system, the image region in the received band-stop filtered image that best matches the contour standard image corresponding to the registered network device of the smart router and whose number of pixels in the band-stop filtered image exceeds or equals a set limit is taken as the current reference region. In the current reference region, each target pixel is identified according to a preset target brightness value range. The target pixels in the current reference region are combined after removing isolated pixels to obtain a target image block to be determined. When the area ratio of the target image block to the band-stop filtered image is greater than or equal to a preset ratio threshold, a registered device presence signal is issued, including: each frame of contour standard image is a pattern data in JPEG encoding format with a fixed resolution.

[0059] The prominent substantive features embodied in the technical solution of this invention are as follows:

[0060] (1) The image region that best matches the outline standard image of the registered network device of the smart router and occupies more than or equal to a set number of pixels in the band-stop filtered image obtained after customized enhancement processing of the surrounding environment image of the smart router device is taken as the current reference region. Each target pixel in the current reference region is identified according to a preset target brightness value range. The target pixels in the current reference region are combined after removing isolated pixels to obtain a target image block to be determined.

Otherwise, a registered device absence signal is issued, thereby realizing a secondary confirmation of whether there is a registered user device around the smart router device.

[0061] (2) A bandwidth adjustment mechanism is installed in the intelligent router device, which is used to turn on the download bandwidth of the intelligent router device and adjust it to the minimum bandwidth value when a signal of the presence of the registered device is received, and to turn off the download bandwidth of the intelligent router device when a signal of the absence of the registered device is received, thereby completing the intelligent management of the download bandwidth of the intelligent router device and avoiding the waste of too much bandwidth resources;

[0062] (3) The customized enhancement processing performed on the surrounding environment image corresponding to the smart router device is to perform sharpening processing based on USM filter, blurring processing without scaling transformation and band-stop filtering processing on the surrounding environment image corresponding to the smart router device in sequence, thereby improving the image quality of the surrounding environment image corresponding to the smart router device.
