The invention relates to the technical field of cable connection, and discloses a multi-channel cable connector which comprises a telescopic take-up protection mechanism and a butt joint mechanism, one end of the telescopic take-up protection mechanism is provided with a locking mechanism, and one side, away from the telescopic take-up protection mechanism, of the locking mechanism is provided with a cable cleaning mechanism. And a connecting mechanism is arranged in the telescopic take-up protection mechanism. According to the multi-channel cable connector, through the arrangement of the telescopic take-up protection mechanism, the butt joint mechanism, the locking mechanism, the cable cleaning mechanism and the connecting mechanism, when the multi-channel cable connector is used, after the end of a signal cable is in butt joint with equipment, the signal cable is partially or discretely connected with a straight mounting block or a bent mounting block; at the moment, the telescopic take-up protection mechanism extends through the sliding locking mechanism, most of the part between the signal cable and the straight installation block or the bent installation block is wrapped and combined, dispersion and disorder are avoided, and meanwhile protection and supporting are provided.

This invention relates to the field of intelligent surveillance technology, and more particularly to an image data retrieval method and system based on surveillance big data. The method includes: extracting the visibility and color features of pedestrian key points from surveillance trajectory segments; calculating viewpoint similarity using the cosine similarity of visibility vectors combined with the ratio of frequency standard deviations; selecting comparable key points and weighting them by the minimum visible frequency; calculating appearance similarity by combining color differences; introducing time constraint parameters to optimize the initial clustering distance to obtain a significant clustering distance; clustering matching for the same pedestrian trajectory; and finally establishing a retrieval index to complete image data retrieval. This invention improves pedestrian information retrieval performance by extracting key point visibility and color information, fusing optimized viewpoint and appearance similarity to construct an initial clustering distance, and optimizing with time constraint parameters to avoid interference from multi-camera scenes.

The application discloses a liquid cooling tray and a forming process thereof, and relates to the field of battery accessory preparation. The forming process comprises the following steps: an initial plate is made of high-strength steel material, and then the initial plate is subjected to pretreatment and cutting treatment respectively to obtain a preformed material and a bottom plate material. A preformed structure is formed at the connecting position of the preformed material. The preformed material is subjected to continuous roll forming treatment to obtain various beam structure parts. The bottom plate material is subjected to shaping treatment to obtain a bottom structure with an assembly reference. Then, the various beam structure parts are positioned and assembled according to the assembly reference to obtain an assembly framework structure on the bottom structure. The beam structure parts in the assembly framework structure are fixedly welded to obtain a connecting framework structure. The connecting framework structure is continuously welded, and the connecting framework structure and the bottom structure are sealed and welded to obtain the liquid cooling tray. The application solves the problem that assembly precision and welding deformation are difficult to be compatible.

This invention discloses an automatically target-changing pulsed laser deposition apparatus and method. The apparatus includes a process chamber, a transfer valve, and a buffer chamber. The process chamber is connected to the buffer chamber via the transfer valve and is configured as an internal vacuum chamber. The buffer chamber has a door at its upper part and operates as a vacuum chamber. A sample stage is located on the upper inner side of the process chamber. Two neck tubes are located on the two sides of the process chamber for guiding an external laser source and mounting a laser detection device, respectively. The process chamber also includes a rotatable target stage for loading and unloading targets from the buffer chamber. The buffer chamber includes a rotating target stage mechanism and a vision camera for placing the target material and recording the bottom features of the target material, respectively. This invention provides an automatically target-changing pulsed laser deposition apparatus and method with a compact structure, precise positioning, and automatic target changing capabilities, enabling fully automated deposition of ultrapure thin films.
