The shift from the IT era to the AI ​​era is destined to the transformation and upgrading of new smart city construction to AI smart cities. This is a major turning point in the construction of new smart cities.
In the overall planning of a city's smart city, the following smart science and technology applications were first proposed in the country:
Intelligent science is an interdisciplinary subject, and there are mainly theories and implementation technologies of brain intelligence, cognitive science, artificial intelligence, intelligent analysis and other disciplines that jointly research intelligent behaviors.
Intelligent science provides a smart technology foundation for smart cities and supports intelligent identification, integration, calculation, monitoring, and processing of massive information in smart cities.
(1) Behavior Analysis Technology
The intelligent behavior analysis system is mainly based on the background modeling technology: in the static scene (the camera does not have a displacement), it finds the dynamic target that is the main human defense object, and performs an alarm according to the set alarm rules. It can be used in key monitoring areas such as schools, residential quarters, high-grade office buildings, factories, government agencies, police station interrogation rooms, highways, etc. in the construction of the safe city monitoring system. It can be used to detect suspicious target intrusions, cross the guard surface (virtual fence), and gather people together. Suspicious stayers, illegal parking, and the leftover of suspicious items, etc., found that an abnormality was reported in a timely manner, and the target suspicious behavior was handled in a controllable state of affairs.
(2) License Plate Recognition Technology
The license plate recognition technology can realize the capture of the license plate of the current vehicle and the license plate number recognition function. In the safe city's visualized prevention and control system, high-definition bayonet monitoring systems and high-definition electronic police monitoring systems are mainly used to achieve real-time snapshots of passing cars, and to achieve license plate recognition, car body color identification, vehicle model recognition, and other technologies. The business management platform realizes the real-time recording of car information.
(3) Face recognition technology
Face recognition is the use of video capture to capture and save the biometric data of captured images, mainly including capture, identification, comparison, search and other functions, in the community entrance and exit, important card points (railway station, bus station, airport Etc.) Deployment to achieve the collection of face information for incoming and outgoing personnel. On the one hand, it can be used for the containment and interception of suspicious persons in a small area. Once a suspicious person's face is detected in the system deployment area, an alarm is generated, and on the other hand, face recognition is performed. The system can build a database of face information to do basic work for later case investigation and personnel investigation. The face recognition system has passed the test of many projects and is matured and commercialized in a number of safe city projects.
(4) Video stitching technology
There are many city surveillance areas and a wide range of areas. For cameras, airports, runways, highways and other places, multiple video cameras need to be covered in order to collect video information. When the monitoring center browses the monitoring screens, multiple monitoring windows need to be opened, and the video browsing screen is discontinuous. Individual important monitoring links are often overlooked. In view of this situation, a video splicing software came into being. The video splicing algorithm library spliced ​​a number of images into a single image and displayed them. The video and area display of the spliced ​​screen images can be achieved. The software can be implemented horizontally. ~8, 1 or 2 images in the longitudinal direction are stitched, and the coincident part is removed to correct the deformation, making the monitoring area wider and more effective.
(5) Video Quality Diagnosis
Video diagnosis technology is the application technology and solution for monitoring and warning of video picture quality. Adopts the means of configuring according to plan to implement round-trip inspection of the front-end video surveillance image screen. Once abnormal conditions such as loss of monitor screen image, brightness abnormality, image color shift, fringe interference, snowflake interference, PTZ pan tilt control, etc. are detected, they are generated in time. The alarm notification maintenance personnel effectively ensure the video surveillance image quality and ensure the reliable operation of the system.
As can be seen from the above plans, the construction of AI smart city is moving in different directions!
Let us enter this era of great AI smart city!
Paraffin Wax
According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
Crude paraffin wax has a higher oil content and is mainly used for making matches, fiberboard, tarpaulin, etc. Fully refined paraffin and semi-refined paraffin are widely used, mainly used as components and packaging materials for food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, used for fruit preservation , Insulation of electrical components, improve rubber aging resistance and increase flexibility, etc.
Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and white or light yellow translucent solids. Paraffin wax is non-crystalline, but has a clear crystal structure. There is also artificial paraffin.
Paraffin wax is a kind of petroleum processing product, a kind of mineral wax, and a kind of petroleum wax. It is a flake or needle-shaped crystal obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, pressing and dewaxing of lubricating oil fraction obtained from crude oil distillation, and then solvent deoiling and refining. Used to make higher fatty acids, higher alcohols, matches, candles, waterproofing agents, ointments, electrical insulating materials, etc.
