Everyone said that Jiangnan is good, and tourists are only Jiangnan. Spring water Bi Yutian, painted boats listening to rain and sleep. West Lake, Qiantang River, White Lady... As a world-famous historical city, Hangzhou attracts tourists from all over the world with its “valueâ€. Today's Hangzhou also has the reputation of "the capital of wisdom and security." The city is full of "Internet +" genes and has made great progress in the construction of smart cities.
The construction of “smart cities†in Hangzhou is, to a considerable extent, initiated by the security industry. After many years of accumulation and passing through the stage of “seeing flowers in the fog and touching stones and crossing riversâ€, it has now shown a trend of vigorous development. Whether it is said that "Safe City" is an important part of "Smart City", or that "Smart City" is an inevitable trend for the future development of "Safe City", neither of these can be treated separately.
Hangzhou wisdom top security planning
Building "Wisdom Hangzhou" is not a day's work. Historically, the lack of breadth of data collection, scattered information resources, the lack of a unified platform, the inability to share resources, and the lack of depth of information mining have been troubling issues. They have also plagued the Hangzhou government and government departments that are exploring the construction of smart cities. How to crack? General Secretary Xi has used the wisdom of China to warn the world at the summit in Turkey: To treat the disease, take the pulse first and then re-open the party!
In this regard, the government and departments represented by Jianggan District, Xiaoshan District, and Lin'an District in Hangzhou proposed the latest three-dimensional prevention and control concept of “Tianwang+District+Social+Social+Multidimensional Perception†to create “High-density Smart Server + Deep Learning Front-End + Cloud-Structured "The safe and intelligent city-wide advanced technology concept is integrated in the entire network, and through the top-level design, it controls the overall construction. The reference architecture diagram is as follows:
Multidimensional perception: Dynamic, real-time source data is the basic support for a three-dimensional security prevention and control system. Create new and accessible smart awareness devices (video surveillance, vehicle bayonet, face mount, video access control, WiFi hotspots, RFID information, electronics, etc.) in the space of people and vehicles (communities, roads, social areas, etc.) Tracks, etc.) Automatically collect information such as people, vehicles, certificates, and electronic trajectories, and increase the integration of business data, social resources data, and Internet data.
Multiple network aggregation and distribution: * Video private network, * Intranet, Internet, operator VPN private network, e-government video private network and other networks to build video, pictures, and IOT data that can access and forward different networks The internet.
View aggregation resource pool: Aggregates various types of resource information, provides massive data retrieval, big data analysis, and big data mining services, and forms a big data service center, providing elastic distribution of cloud computing and cloud storage resources for upper-layer applications, and supporting a variety of big data The computing needs, as well as massive video structured processing, picture analysis, face matching and other services, meet the needs of police data big data analysis and storage.
In-depth application: Integrate three-dimensional security and prevention and control with accurate strikes, combat patrols, video surveillance, intelligence research and judgment, command and dispatch, human-vehicle deployment and control, and intelligence and command linkages; provide a variety of techniques and methods (footing analysis, Gangs analysis, search by maps, etc.) provide practical application for each type of police to achieve the purpose of providing information to the police; through the mobile Internet, it provides citizens with convenience services such as traffic congestion information, public security announcements, vehicle management operations, and suspicious reporting.
Big data display: Data exchange and display through various forms such as unified portal, web interface, mobile phone APP, big data graph wall, and visual report.
Such as brushing the face, vehicle identification, vehicle tracking, infrared thermal imaging, squatting alarm, flat scheduling, emergency command, big data applications, multi-dimensional perception of three-dimensional prevention and control, we see a variety of "future world" in the Hollywood blockbuster "Black technology has long been implemented in Hangzhou."
The author uses the security and technology 18 martial arts demonstrated by the Dahua Group to protect the G20 summit as an example to illustrate the application of various high-tech Jian Anfang big data technologies in the construction of smart Hangzhou.
Smart Security Big Data Application
Vehicle Big Data Judgment System for Comprehensive Control of High-Risk Vehicles
At present, the application of video images has penetrated into the construction of various social stability maintenance operations. How to use “accurate use†on the basis of “seeing clearly†is an increasingly concerned topic for the department. The view data is a valuable asset of public safety. The value of the application system is “three points in technology and seven points in dataâ€. The established safe city system has accumulated a large amount of bayonet data and picture videos, but existing applications still only stop. On a simple post query. Hangzhou has more than 2 million vehicle ownership and over 30 million daily trips. Through electronic, security bayonet, and road monitoring, a large number of passing records and passing pictures will be generated each day. How to further use a large amount of view data, and link a large number of online business data for big data collision analysis, effectively tap the value information of the view and serve the various police types, it is the actual value of Dahua vehicle big data system.
Dahua's vehicle big data system can not only accurately identify the time, location, behavior trajectory, license plate number, color, annual inspection, and other key information of vehicles marked with more than 200 brands of 3,000 types of vehicles, but also can effectively link with the business system. Real-time judgment on whether the owner of a car comes from a high-risk area, whether it is an at-risk person, whether he has a criminal record, whether he has a drug addict, etc., or even the information of the car owner's associated social worker, to provide a comprehensive basis for the judgment, and for high-risk vehicles, high-risk People do real-time warnings, track them in real time, and implement interception, which greatly enhances the actual combat effectiveness of the police and creates a huge deterrent against illegal crimes.
Portrait recognition system to build "Portrait Skynet"
Portrait big data applications are designed to make full use of existing policing data and video image data to more effectively meet the needs of personnel escaping, identification and personnel control, and to use portrait big data systems to put high-risk and key personnel in metropolitan areas. Level dispatching control, through the depiction of the typical target personnel trajectory, carries out early warning of high-risk behaviors. For those individuals who are unable to confirm their identity, such as widows and widows, non-identified individuals, and deaf and dumb people, they can take photos of their faces through mobile phones, cameras, etc., and compare them with resident populations or floating population banks to verify identity information.
In the core areas and important transportation hubs in Hangzhou, the Dahua Portrait Interchange is deployed. The real-time portrait data captured by it can automatically collide with the blacklist library. When high-risk and key personnel appear, the system will immediately issue warning information to notify the front-line police to respond and deploy in a timely manner. The system played an important role during the G20. When the system was still in the testing stage, it helped the police to catch several fugitives.
The system is also real-time deployment of unlawful people around the community in the construction of the Ping An district in Hangzhou. The owner can identify the facial features outside the unit's door, and through face recognition, the door can be opened if the comparison is successful. Improve the grade of the community, as a bright spot for community construction, to facilitate the owners.
Video extraction technology massive view efficient analysis
Since thousands of cameras in smart cities are built in stages, a large number of old front-end devices do not have the identifiable structure of video. It is impossible for these massive non-smart cameras to upgrade to smart cameras in a short period of time. Therefore, deploying an extraction system at the center can quickly structure the video streams of non-smart cameras and extract structural information such as people, vehicles, and objects. . These structural information are then further connected to the vehicle big data system and face big data, providing continuous data support for intelligent control of people and vehicles. This is a prerequisite for the effective work of vehicle big data systems and face big data.
Cloud Enrichment / Cloud Abstract
On the basis of the extraction of video data, it is not easy to quickly search and view the massive view data brought by tens of thousands of monitoring devices. Dahua Cloud's enrichment abstract technology can analyze massive videos at a very fast speed to form summary pictures and related descriptions. It can help the authorities retrieve and locate key information such as key people and cars in seconds, and acquire suspect targets in real time, realizing “viewing†and “searchingâ€. The change of goals will achieve a second-level search of hundreds of billions of data, fully satisfying the video structure analysis under different scenarios and scales during the summit.
One machine, one file management and one button operation and maintenance, global equipment is easy to control
The G20 Hangzhou Summit has invested tens of thousands of front-end and back-end monitoring equipment. In the core area and around the summit, Dahua provided more than 20,000 units/sets of security equipment. With so many equipments, it is difficult to rely solely on human maintenance. Dahua Investment's visualized operation and maintenance management system can establish a complete and detailed "family-owned archives" for all monitoring points, and conduct scientific, informative, and refined management of the point-based "hukou archives"; Operation and maintenance can timely and comprehensively detect the operating status of the system and equipment, automatically output fault reports, and facilitate timely maintenance, so as to ensure smooth operation of all monitoring points during the summit and ensure the integrity of the video surveillance content.
Flat command dispatching system for rapid visual command dispatch
The Dahua Flat Command and Dispatch System builds a powerful command and dispatch platform with horizontal integration and vertical flatness. It displays video surveillance, police force, police cars, blocking control points, intercepting stations, hospitals, schools, key locations, and key points in real-time on electronic maps. Resources such as personnel, realizing the rapid response of the emergency department, reasonable and efficient resource scheduling, and rapid deployment of key areas; in commanding and dispatching actual combat, multi-dimensional information or instructions such as audio, video, image, and text can be delivered to the frontline police in real time. Achieve real-time coordinated operations across police types, fully supporting rapid response from frontline, multi-policing, and efficient implementation.
Big Data Intelligence Analysis Multidimensional Trajectory Reduction
Based on the big data intelligence system, centering on dimensional stability and case investigation, using big data analysis technology, deep learning and pattern recognition technology, distributed cluster computing, and real-time search engine technology, people, vehicles, and objects in the center's video data are analyzed. Structured data for analysis. Through mining, colliding, and analyzing the value of massive structured data, the “key personnel information†mining, “personnel relationship†mining, “personnel trajectory†mining, “vehicle comprehensive information†mining, and “human-vehicle topology relationship†mining are realized. Effectively identify high-risk personnel, illegal vehicles, and realize the excavation of the relationship between people and vehicles, accurately locate the trajectory, and real-time management and control. After discovering a suspect target, you can view the restored trajectory on the map, including vehicle trajectory, personnel trajectory, MAC trajectory, and so on. The data comes from the vehicle bayonet, face bayonet and MAC acquisition equipment. It shows the time and place where the target appeared. The final trajectory can be comprehensively presented on the map.
Conclusion
The construction of smart cities is the inevitable trend of the future development of public security, and it is the current trend of global technological change and the new round of industrial development. Each city must give full play to the advantages brought by information technology to develop urban construction. Standing on the banks of the Qiantang River in Hangzhou, Dahua will continue to enhance its ability to innovate, continuously pursue world-class quality, maximize customer value, and demonstrate the determination of the best companies to serve the country.
