Abstract: A method for determining a logistics routing network, including: obtaining line data of a line to be optimized, stowage data of stowage to be optimized, and associated routing of the stowage to be optimized; determining an associated line set corresponding to the stowage to be optimized according to the associated routing of the stowage to be optimized; generating a line sub-network to be optimized according to the associated line set; obtaining a routing sub-network to be optimized by adding corresponding line data and stowage data to the line sub-network to be optimized based on the line data of the line to be optimized and the stowage data of the stowage to be optimized; and screening out target routing in the routing sub-network to be optimized according to a transportation cost, and further determining a target logistics routing network.

Abstract: A delivery robot includes: a mobile chassis and a housing provided on the mobile chassis. The housing comprises a bottom plate, at least two first supporting members, and a top plate; the bottom plate is provided at the top of the mobile chassis, and the at least two first supporting members are provided between the bottom plate and the top plate, and are respectively located on two sides of a front end or two sides of a rear end of the bottom plate, wherein the front end of the bottom plate is a front surface of the housing, and the rear end of the bottom plate is a back surface of the housing.

Abstract: A chassis for an edge device includes a cabinet and a heat exchange component. The heat exchange component is disposed in a space enclosed by the cabinet. The space in the cabinet is divided into a first space and a second space for placement an electronic device. The heat exchange component performs heat transfer between the first space and the second space. A first air inlet and a first air outlet are disposed in the first space, and an airflow entering from the first air inlet flows through a first surface of the heat exchange component and exits from the first air outlet.

Abstract: The present disclosure provides an experiment platform for simulating fire in an underground traffic conversion channel, including: a model body configured to simulate fire in the an underground traffic conversion channel; a burner connected to the model body and configured to generate smoke; and a smoke imaging system including laser sheet light sources and image recording devices configured to record smoke distribution images. The laser sheet light sources are in the model body, and plane laser light emitted by the laser sheet light sources is parallel to a flow direction of the smoke. The image recording devices are in one-to-one correspondence to the laser sheet light sources and are arranged outside an observation window of the model body. One laser sheet light source and one image recording device corresponding thereto each have a filter configured to filter out laser light of a same wavelength.

Abstract: The present disclosure describes techniques of processing information flow and synchronously displaying image s, mask frames and comment information. According to the present disclosure, a system processes a first information stream uploaded by a stream pushing terminal to obtain a frame image and mask frame data, the mask frame data corresponding to the frame image and identifying a timestamp offset indicative of a time difference between the mask frame data and a playing timestamp of the frame image. The system synthesizes the frame image and the mask frame data to generate a second information stream; and output the second information stream to a client for synchronously displaying the image frame, a corresponding mask frame, and the comment information.
