A 6,000-square-meter digital exhibition hall was also set up at the conference site, focusing on the information fusion data platform, AI open platform, intelligent applications in various industries and the latest products.

　　Frontier point of view: intelligent internet of things, integration of things and information, release data value and meet industry applications.

　　Hu Yangzhong, president of Hikvision, gave a keynote speech at the meeting, "Intelligent IOT, Integration of Things and Information to Meet the New Era of Intelligence". Hu Yangzhong pointed out that the Internet of Things has developed to this day, and the combination with AI has become the driving force for leap-forward development. Intelligent Internet of Things is the infrastructure of the intelligent era. After the Internet of Things realizes intelligence, it is not enough to serve the industry alone. It needs to be closely integrated with various information networks such as the Internet and industry information networks, and the connection between intelligent objects and information systems needs to realize the integration of things and information, which is the data meridian of the intelligent era.

　　Application is always the starting point and focus of industry users. In the past, more data was generated from applications; In the future, with the intelligent Internet of Things sensing a large amount of data, and realizing the integration with information network data through the integration of things and information, the mining and utilization of data will bring more space, and we will usher in the era of data application.

　　While the value of data is constantly improving, the demand for data security and privacy protection is becoming stronger and stronger. Data protection will become the escort ship in the intelligent era. Hu Yangzhong said that Hikvision is making continuous efforts in user data security protection and privacy protection. At the summit, Wan Li, a security expert of Hikvision, released the "White Paper on AI Cloud Security", which expounded Hikvision’s active efforts in this regard.

　　Hu Yangzhong also pointed out that open integration is a new format in the intelligent era. For enterprises in the wave of industrial development, the most important thing to grasp in the future is the development trend of openness and integration. Only openness can lead to cooperation and integration, and only cooperation and integration can make the industry bigger. In order to achieve open integration, Hikvision has established an open system. Open the edge computing, algorithm training, Internet and industry application capabilities through edge equipment open platform, AI open platform, fluorite open platform and industry open platform; At the service level, provide an integrated operation and maintenance service platform to support the opening of integrated operation and maintenance services that join the operation and maintenance mode; Provide an open evaluation capability of IOT resource deployment, support more products to be included in the evaluation system, and jointly improve the IOT resource capability evaluation model. In terms of technical standards, Hikvision will open up an enterprise standard system related to cooperation and integration.

　　Heavy release: Hikvision integrated data platform helps users realize cross-network data fusion and application.

　　The integration of things and information is not just an idea. At the meeting, Dr. Bi Huijuan, senior vice president of Hikvision, released the data platform of the integration of things and information in Aichloud, and emphatically introduced the main capabilities of the platform, including horizontal cross-network integration, vertical cross-layer convergence, dual-network applications, and ensuring data security.

　　The so-called horizontal cross-network integration, first of all, is the source governance to solve the quality problem of the source of intelligent IOT data; Secondly, intelligent analysis, using artificial intelligence to transform IOT data into easily understood data such as people, places, things and things in the information network; Then there is the IOT data service, that is, while supporting the IOT intelligent application, the data can be sent to the information network as needed to be integrated with other data; Finally, the data governance is integrated, and the data is organized according to the ways of subject library, subject library, tag library and relationship library. And then provide integrated data services to support the development of information network data applications.

　　Secondly, the vertical cross-layer convergence ability. The AI Cloud IoT data platform provides the data platform cascade function, which supports the data to converge upward as needed in both the intelligent Internet of Things and the information network.

　　In the intelligent Internet of Things and information network, based on the intelligent application platform, three types of applications can be developed: single scene application of edge nodes, space-time application of edge domain and macro-integrated application of cloud center.

　　In addition, in the information fusion data platform, we pay attention to the data protection ability provided by the product itself from four aspects: data collection, transmission and storage, data service and data application; Pay attention to the data protection ability provided in the process of data engineering services from four aspects: development and testing, delivery and implementation, data governance and operation and maintenance services.

　　Dr. Bi Huijuan said that in 2017, Hikvision had proposed the basic concept and architecture of AI Cloud. In 2018, under the guidance of cloud computing architecture, the company developed two pools, one library and four platforms, and some pioneer users have started to use these products. On this basis, the company deepened the capabilities of two pools, one library and four platforms, further clarified the data architecture of information fusion, and deepened and integrated the original products into the information fusion data platform. It can be predicted that 2019 will be the year when Hikvision AI Cloud will be fully launched. On the one hand, the information fusion data platform will gradually mature and will be applied to more industries. On the other hand, local business centers have also prepared localized data governance project implementation teams to provide services to users.

　　Application Practice: Enjoy the Intellectual Property of Digital World.

　　Xu Ximing, senior vice president of Hikvision, said at the "Zhiyong Qiantang" 2019 AI Cloud Ecological Conference that digital transformation and integration of things and information will become an inevitable choice for society and enterprises. More than 80% of the information in the physical world is visual information. Xu Ximing believes that visual perception is the most effective digital means of the Internet of Things, and visual big data will become the core driving force of industrial intelligence.

　　"Visual perception bridges the digital world and gives insight into cognitive laws. "Xu Ximing said that Hikvision has been applied in various industries such as security, finance, manufacturing, warehousing, logistics, energy, education and retail.

　　The deputy general manager of CCTV mentioned that CCTV and Hikvision have achieved technical cooperation in the "Live China" channel, and launched different types and levels of video content through five sub-columns: slow live broadcast, mobile live broadcast, panoramic VR, short video and aerial video, and also integrated AI technology and video technology into content production to meet the needs of the audience; Li Changjiang, executive director and general manager of Country Garden Service, shared the exploration of smart community. Country Garden Service and Hikvision cooperated to set up a joint laboratory, developed a community neural network based on cloud, domain and node, and endowed the community with brains. With the application of new technologies such as robots and AR glasses, the safety level is improved, the service is more intelligent and insensitive, the working ability of front-line employees is improved, and finally the owner benefits. Huang Shaofeng, chairman of Aoya Bio, brought a sharing about the wisdom development of pharmaceutical companies. Apply visual perception and artificial intelligence algorithm to make up for the shortage of manual supervision, eliminate human error, realize the visualization of production process, query deviation data, intelligent supervision in production line, unmanned logistics in warehouse, refined park management, and prevent compliance and quality control risks. Han Aisheng, general manager of CUHK, shared the enterprise-level project management based on smart construction 4.0. Sino-CUHK, together with Hikvision, applies visual perception and artificial intelligence technology to create a command center, enterprise-level large-screen management and mobile office receipts, serving enterprises to implement policies and regulations, avoiding enterprise-level risks, and creating and landing standardized solutions. At the same time, access the AI open platform in the management of tower cranes, seals, elevators and other equipment and materials.Realize intelligent management.

　　Although the demand for digital transformation and intelligent development in the real economy is very strong, it is not so easy for traditional enterprise AI to land due to the limitations of data, algorithms, computing power, products and systems. Pu Shiliang, senior vice president of Hikvision and dean of the research institute, said that in order to empower industry users and help industrial upgrading, Hikvision launched the AI ​ ​ open platform last year. On the one hand, it can enable industry users with zero algorithm basis to train their own algorithms for application scenarios, on the other hand, it can enable many AI practitioners to have their own intelligent hardware.

　　Hikvision’s AI open platform has three characteristics: first, it can quickly generate AI algorithms that meet the needs of scenes based on a small amount of data; Second, the training optimization of the algorithm can be realized automatically; Third, based on the hardware foundation of Haikang, open smart products with strong perception.

　　Pu Shiliang introduced that in the past year, Hikvision has successfully applied the AI open platform to intelligent upgrades in environmental protection, logistics, tourism, meteorology, urban management and other fields.

　　Overseas network April 4 thAccording to the reports of Reuters and Russia Today TV, on April 3, local time, thousands of people in Britain staged protests against the police law in many places. Among them, in front of Parliament Square in central London, police clashed with demonstrators, and at least 10 policemen were injured and 26 people were arrested.

　　It is reported that on March 10th, the British government announced the latest draft legislation of Police, Crime, Trials and Courts. The bill gives the police greater law enforcement power. This draft has caused public dissatisfaction, and there have been anti-police law protests in many places in the UK for several weeks. On April 3rd, protests were held in London, Newcastle, Birmingham, Liverpool, Bristol and Brighton.

　　The protest in London on the 3rd was peaceful at first, and then there was a small-scale conflict between the demonstrators and the police. Some of the demonstrators attacked the police with slingshots. The Metropolitan Police of London issued a statement saying that the police deployed a large number of police forces that day, arresting 26 people and slightly injuring 10 policemen.

　　Ed Adlekan, commander of London Metropolitan Police Department, said on the 3rd: "In the demonstrations that took place in London that day, most people tried to abide by the social segregation regulations, and only a few people blocked the road in Parliament Square. The on-site police advised him to retreat in order to restore road traffic. " (Overseas Network Zhang Qi)

　　The layout of the Forbidden City embodies the designers’ wisdom. The clever thinking of "facing the mountain and facing the water" is one of the obvious characteristics. Jingshan Mountain is in the north of the Forbidden City, and Neijinshui River is in the south. There were no mountains in Beijing. When the Forbidden City was built in Yongle period, more than 1 million cubic meters of soil was excavated by opening a moat, and the piles of muck demolished by the Yuan Dynasty Palace could not be treated. So, a "waste utilization" came, which piled up the soil into mountains and planted trees on them. This is the Zhenshan in the north of the Forbidden City. Zhenshan was called "jingshan park" in the Ming Dynasty, and it was renamed "Jingshan" in the Qing Dynasty, and it has been used ever since. Jingshan is the commanding height in Beijing, which is east-west and narrow in the north-south direction, much like a screen. At the same time, when the Forbidden City was built, a culvert was dug downstairs from the northwest corner to introduce the moat water into the city. This is the specially dug Jinshui River. Jinshui River winds south through Chenglong Temple, winding all the way, turning east through Wuying Hall, passing Taihe Gate and Wenyuan Pavilion, and flowing out of the Forbidden City from the southeast corner. Jinshui River not only provides drainage channels for people in the Forbidden City, but also echoes with Jingshan Mountain, forming an aesthetic image of mountains, rivers and mountains in harmony. The surface of Jinshui River is lower than the ground of the Forbidden City, and the main part of the Forbidden City is built on the balcony between Jingshan and Jinshui River. Through Jingshan and Jinshui River, the Forbidden City is in harmony with nature in the aesthetic sense.

　　"negative yin embraces yang" is also a feature of the layout of the forbidden city. All the important palaces in the city face south. Chapter 42 of Laozi’s Tao Te Ching says: "Everything is negative and holds Yang, and rushing into the air is thought to be harmonious". It means that everything in the world is shady and sunny, and yin and yang interact to form a new harmonious body. The important palace buildings in the Forbidden City face south, with a large number of doors and windows in the south and fewer doors and windows in the north. The Book of Changes, Zhuan Zhuan Zhuan, says, "Sages listen to the world from the south, and govern from the Ming Dynasty", which means that the ancient sages ruled the world by listening to the south and facing the bright sunshine. Similarly, this layout has scientific significance in geography: the Yellow River Basin in China is located in the most remarkable subtropical monsoon climate area in the northern hemisphere, and in winter, a high pressure is formed in the northwest of the Asian continent, with a northerly wind for several months; In summer, the center of high pressure turns to the southeast Pacific Ocean, and the rainy monsoon from the south makes the temperature rise and the summer heat pressing. Under this geographical condition, it is most suitable for the building to face south, with the north side closed to keep out the cold, and the south side with windows for sunlight and ventilation in summer.

　　Another feature of the layout of the Forbidden City is "taking the positive center". "Correcting" means that the north-south direction is the main axial direction of the building layout. This is mainly due to the construction experience of ancient Chinese craftsmen based on the geographical location and natural environment of China, that is, the main seat faces south and is symmetrical left and right. "Centripetal" means that all secondary buildings face the main building. All the ancient buildings in the Forbidden City are mainly quadrangles, with the main rooms facing south and the wing rooms facing east and west. This centripetal architectural style not only makes the distance between houses smaller, which is conducive to the convenience of transportation, but also reflects the idea of "China is supreme" and "China is still big" in ancient China culture. At the same time, this orientation layout reflects the unity and coordination of the ancient buildings in the Forbidden City, and there is no sense of clutter.

　　The architectural division of the Forbidden City is also particular. From the perspective of architectural functional zoning, the layout of the Forbidden City includes the imperial court area and the imperial court area. The buildings of the former dynasty were located in the south of the Forbidden City, mainly including the Hall of Supreme Harmony, the Hall of Zhonghe and the Hall of Baohe (commonly known as the Three Great Halls), which was the place where the emperor held important ceremonies. The imperial palace buildings are mainly located in the northern part of the Forbidden City, including Ganqing Palace, Jiaotai Palace, Kunning Palace (commonly known as the last three palaces) and the East and West Six palaces, which are the places where emperors and empresses live. The three great halls of the former dynasty occupied a large area and formed a huge pattern in the Forbidden City. These three buildings stand on a three-story platform, which is 8.13 meters high and takes the form of Sumitomo. Sumeru is actually the base of the Buddha statue. "Sumeru" is an Indian Buddhist term, which means "the center of the universe". Sumeru is used as the foundation of the building, which means that the building is stable and long-lasting. The three-story platform of the three halls can highlight the grandeur and height of the building, form an obvious contrast with other buildings in the Forbidden City, and highlight its extraordinary position. Not only that, the three halls are elegant in richness and dignified in exquisiteness, which highlights the majesty of the emperor. The Three Great Halls are not only the center of the Forbidden City, but also the center of Beijing, with the axis from Yongdingmen in the south to the Bell Tower in the north, becoming a straight central line. On both sides of this axis, buildings with less important functions are arranged symmetrically and orderly in turn. There is also a square with an area of 30,000 square meters in front of the Hall of Supreme Harmony. This layout is conducive to showing a grand scene when holding important ceremonies.For the six palaces of the East and West, they are symmetrically arranged and vertically arranged. These buildings are separated vertically and horizontally by the East-West Second Long Street and the alleys in front of the palace, forming a very regular and rigorous closed space with streets and lanes, and the doors and walls of the seats are connected and separated. In their own space, that is, in the independent courtyards of each palace, they have the same layout and basically the same architectural form. The plane of each palace is square, and the layout is in the form of a three-in-one courtyard with two courtyards. The front hall and the back bedroom are all equipped with halls, which are strictly symmetrical. The layout of the courtyards of the East-West Six Palaces is subtle and compact, which not only guarantees the privacy of the life of the Empress Dowager, but also has reasonable planning: "How deep the courtyards are" can reflect the location characteristics of the East-West Six Palaces in the Forbidden City. On the whole, the architecture of the former dynasty was Yang, and Yang was majestic and tall. The architecture of the imperial palace is yin, and yin converges to the reality of hiding. The six palaces in the east and west and the three halls form a harmonious and unified wisdom thought of rigidity and softness, yang and yin.

　　In addition, the architectural layout of the Forbidden City was convex in the former dynasty and concave in the imperial palace. The combination of convex and concave is just like a mortise and tenon. This layout of tenon-mortise connection not only shows the ingenious tenon-mortise locking concept of the ancient buildings in the Forbidden City, but also embodies the concept of "Yin and Yang in one" in ancient Chinese architectural culture, which is a reflection of the wisdom of the builders of ancient architecture.
