Abstract: The present disclosure provides a control method, device and system of a cleaning robot and a storage medium, and the method includes: obtaining one or at least two preset frequencies of an edge patching cleaning task, and controlling the cleaning robot to perform the edge patching cleaning task on a preset cleaning region according to the preset frequency/frequencies. The cleaning effect of the preset cleaning region is improved by controlling the cleaning robot to perform the edge patching cleaning task, and by controlling the cleaning robot to perform the edge patching cleaning task according to the preset frequency, the cleaning efficiency and the cleaning effect can be balanced, so the cleaning robot is more intelligent, and the user experience is better.

Abstract: A controlling method and apparatus of a cleaning robot, a cleaning method and apparatus, a system, and a storage medium are provided. The method includes: controlling the cleaning robot to mop a preset cleaning region through a mopping member; obtaining a first dirtiness degree corresponding to the preset cleaning region; determining that the preset cleaning region includes a target region according to the first dirtiness degree, the target region being a region that needs to be repeatedly mopped; and controlling the cleaning robot to mop at least part of the target region through the mopping member after mopping of the preset cleaning region has been completed and after maintenance of the mopping member.

Abstract: An early warning method for hot spots of a brake disc includes: acquiring a mixed vibration signal generated when the brake disc is braked; separating the mixed vibration signal to obtain multiple separated vibration signals; and screening the multiple separated vibration signals to obtain hot spot determination signals. The hot spot determination signals are configured to determine formation of the hot spots on the brake disc. By separating the mixed vibration signal generated when the brake disc is braked, the multiple separated vibration signals can be obtained. Each of the multiple separated vibration signals is screened to obtain the hot spot determination signal that reflect whether the hot spots are formed on the brake disc, and the hot spot early warning result is reliable. The early warning method can effectively improve the accuracy of hot spot early warning for brake discs.

Abstract: The present application relates to the field of cell immunity, and discloses an interacting protein screening platform for preparing a cell membrane. A cell membrane protein and a membrane protein encoding gene to be tested are respectively expressed in different cells; after staining, cells expressing different membrane proteins and cells expressing target proteins are co-incubated; and then interacting membrane proteins are obtained by screening, and specific sequences thereof are determined by sequencing. The screening platform provided in the present application can screen a variety of cell membrane proteins and membrane protein-based engineering cells, and has strong specificity, thereby greatly improving the efficiency of screening interacting proteins and reducing the difficulty, providing a simple and convenient tool for studying the mechanism of action of cell membrane proteins, and improving the screening throughput.
