Abstract: An automatic conveying device and an automatic cleaning device for the handrail belt thereof. The automatic cleaning device includes a base; a first cleaning unit and a second cleaning unit mounted on the base, the first cleaning unit and the second cleaning unit are arranged in a front and back way in a moving direction of the handrail belt; a cleaning liquid conveying device, for conveying cleaning liquid to the first cleaning unit or the second cleaning unit; and a controller configured to control the cleaning liquid conveying device to deliver the cleaning liquid to one of the first cleaning unit and the second cleaning unit that first comes into contact with the handrail belt based on the running direction of the handrail belt during the cleaning operation.

Abstract: A task scheduling method and system, and a hardware task scheduler are disclosed, and pertain to the field of computer technologies. The hardware task scheduler provides task scheduling for a central processing unit CPU core to select a candidate task. After selecting the candidate task, the CPU core actively sends metadata of the candidate task to a first storage area, and actively sends a context of the candidate task to a cache, where the first storage area is located in storage space whose access speed is higher than that of a memory. When performing task switching, the CPU core reads the metadata of the candidate task from the first storage area, and reads the context of the candidate task from the cache. In this way, latency of obtaining the metadata and the context of the candidate task by the CPU core is reduced, and low-latency task switching is implemented.

Abstract: A ventilation control method for a laundry device to solve problems related to bacteria after clothes are washed in a laundry device, due to the moist interior of a drum assembly thereof. When an air intake fan is started, the present current of the air intake fan is acquired; if the present current of the air intake fan reaches a pre-set current value, water is injected into a water intake pipe to trigger a siphoning apparatus to discharge water from the water intake pipe, and a drum assembly is then ventilated; and if the present current of the air intake fan does not reach the pre-set current value, the drum assembly is directly ventilated. After clothes are washed, residual water inside a drum assembly can be air-dried, preventing breeding of bacteria and generation, and clothes are not subjected to secondary pollution during subsequent washes, thereby improving the user experience.

Abstract: An additional brake device for a passenger transport device, a brake disc assembly, a wheel disc assembly, and a passenger transport device. The additional brake device comprises: a brake disc defining a hole and having an inner circumferential surface; a wheel disc having a wheel disc body and an extension, the extension being fitted into the hole of the brake disc and having an outer circumferential surface, and a first friction plate being provided between the brake disc and the wheel disc body; and a pressure holding mechanism which maintains a pressure between the brake disc and the wheel disc, wherein an intermediate member is provided between the inner circumferential surface of the brake disc and the outer circumferential surface of the extension of the wheel disc, the intermediate member comprising a metal or alloy material.
