Abstract: The present disclosure discloses a smoke detection system and a smoke detection method. The smoke detection system includes a camera, a storage unit, and a processor. The camera acquires a current image and a previous image. The storage unit stores a plurality of modules. The processor is coupled with the camera and executes the plurality of modules. The processor generates a difference image based on the current image and the previous image. The processor inputs the current image and the difference image to a semantic segmentation model so that the semantic segmentation model outputs a smoke confidence map. The smoke confidence map is generated based on whether a current environment is a dark environment or a bright environment. The processor analyzes the smoke confidence map to determine whether a smoke event occurs in the current image. Therefore, a reliable smoke detection function can be achieved.

Abstract: The USB chipset including a data processing unit, a transmitting unit, a first pin set and a second pin set is provided. The data processing unit generates a plurality of transmission information according to first information provided by a first device. The transmitting unit processes the transmission information to generate an output signal. The first pin set is configured to transmit the output signal to a second device. The second pin set is configured to transmit the output signal to the second device. When the first pin set transmits the output signal to the second device, the second pin set does not transmit the output signal to the second device. When the second pin set transmits the output signal to the second device, the first pin set does not transmit the output signal to the second device.
