n Challenges faced by video surveillance With the wide application of surveillance video in the * business, video detection technology that finds clues and traces suspect targets from video recordings has become the fourth largest technical means for detecting crimes after criminal technology, action technology, and cyber investigation technology. Detection plays an increasingly important role. However, the increase in the scale of video surveillance has also brought in massive amounts of video data, which makes traditional video cues based on human tactics look like a needle in a haystack. * Case investigation departments have become increasingly demanding in intelligence for various types of police analysis and video rapid analysis and retrieval. At present, the policing informatization method has shown its inability to deal with the situation and is facing the following severe challenges: 1) There are no unified management platforms for different monitoring networks such as safe cities, road monitoring, and social monitoring. Surveillance cameras are widely distributed, management is confusing, and image acquisition is difficult; 2) The variety of video formats and the lack of unified video index management and playback tools have resulted in low viewing efficiency and have limited the use efficiency and scope of video surveillance data. 3) The uneven quality of the video affects the accurate determination of suspected targets by the case officers. 4) Manually viewing video takes time and effort, and leads to loose clues to target. It is impossible to achieve effective clue matching and resource sharing, and it is easy to miss the suspect target and delay the fighter. n Video Investigation Studio V3.0 Thousand Vision Video Reconnaissance Studio V3.0 is a "one-stop" solution for the investigation of video from video capture to intelligent analysis to case resolution.

Video retrieval, human form, color, texture, vehicle rapid recognition retrieval 1 ) Target classification detection technology based on deep learning The video analysis retrieval system incorporates a deep learning algorithm that can accurately distinguish pedestrians, cars, and people from biking goals based on the moving objects in the video, and at the same time classifies and retrieves different features of the same type of target, such as whether or not pedestrians wear glasses and scarves. Whether it is a backpack, a gender classification, etc.; a person's bicycling target can distinguish between two rounds and three rounds of classifications to improve the efficiency and accuracy of target detection. 2 ) video encirclement, fast retrieval of targets When the 110 command center receives the alarm, the command center immediately switches the scene of the crime scene and the nearby area. When the investigators find the suspect or suspect vehicle in the screen of a certain monitoring point, they can directly select the target in the video as the tracking sample. , and then set a valid search range on the GIS map. Once the target is confirmed, the system will automatically form the target movement trajectory, to facilitate the arrangement of road police force rounding. 3 ) International advanced humanoid retrieval and video structuring technology The humanoid search function can quickly perform global search in the cross-camera based on the target suspect's clothing, color distribution, and body features, find similar targets, and then output the results in the form of snapshots and sort them by similarity. 5.

Laboratory hopper mixer is mainly used for the tests of mixing different components of dry powders with dry powders, granules with granules, or powders with granules in laboratories. It is an ideal machine for exploring the best process parameters in material mixing, and a mechanically and electrically integrated advanced experimental machine.
Features:
The laboratory mixer is installed on a moveable base. Its main parts include machine frame, rotation system, electric control system, hopper, etc. The conical mixing hopper is mainly composed of hopper, hopper cover, ferrule, butterfly valve, etc.
The hopper that can rotate at 360° is installed on the rotation shaft by adopting the cantilever fixing mode. As the symmetrical axis of the hopper forms an included angle with the rotary arm rotation axis, different components of materials will make three-dimensional movement in the closed hopper, producing strong turning and high shearing and achieving the best mixing effect.
The rotation system is a key system for completing the mixing function. The rotary motor is a low speed high torque speed reducing motor, which is the power unit for mixing. The rotation shaft is installed with sensing components. When the gyrator turns to the set position, the sensor installed on the machine frame sends the sampling signal. The signal passes through the PLC system, which reads the hopper rotation speed and position information, continuously displays rotation speed and accumulated number of revolutions on the touch screen, and sends stopping instructions according to the set time. The hopper stops rotation, and stops at the best discharging position under the action of the brake motor.
The electric control system is mainly composed of two parts such as the electric cabinet and sensor. The core control parts PLC controller and frequency converter are installed in the electric control cabinet. During the use, the operations of electric appliances are mainly completed on the operation panel (touch screen) of the electric control cabinet, including printer, touch screen, power switch and emergency stop switch. The touch screen displays running time, rotation speed, etc.
