This invention relates to the field of smart gateway technology, specifically disclosing an artificial intelligence-based smart gateway optimization method. The method involves initializing channel quality estimation parameters and setting an uncertainty threshold; sending probe frames to candidate channels during idle periods of service data, and receiving response results as quality samples; extracting received signal strength indication values ​​from the samples and assigning a probe confidence coefficient; updating the quality estimation parameters with weighted probe results using Bayesian inference; calculating the expected performance value of each channel based on the updated parameters; generating a switching command when the cumulative number of times the current channel is continuously inferior to the best candidate channel reaches a threshold and the performance difference exceeds an uncertainty threshold; executing channel switching and resetting the cumulative count; and dynamically adjusting the subsequent probe frequency according to the service load. This invention enables adaptive channel optimization while ensuring service continuity, improving the communication reliability of smart gateways in complex environments.

This invention provides an ultrasonic therapy device and its handle extraction sensing device. The handle extraction sensing device includes a storage bracket and a handle. The storage bracket has a storage limiting cavity extending through the height of the storage bracket. The handle is detachably inserted into the storage limiting cavity. A magnet assembly is mounted on the storage bracket, arranged circumferentially around the storage limiting cavity. The central angle of the magnet assembly around the storage limiting cavity is between 170° and 360°. The handle contains a control module and two magnetic sensing elements, located on opposite sides of the handle. The magnetic sensing elements are electrically connected to the control module. When the handle is placed in the storage limiting cavity, the magnet assembly surrounds at least one magnetic sensing element. The ultrasonic therapy device equipped with this handle extraction sensing device eliminates the need for user adjustment of the handle's position and offers high detection accuracy.
