big data not only means massive, diverse and rapid data processing, but also a subversive way of thinking, an intelligent infrastructure and an innovative technological change

recently, Chen Jing, academician of Chinese Academy of engineering and researcher of Southwest Institute of electronic and telecommunication technology, analyzed the "development trend and security issues of in-depth application of information big data"

he proposed that big data not only means massive, diverse and rapid data processing, but also a subversive way of thinking, an intelligent infrastructure and an innovative technological change

,, augmented reality (AR) and virtual reality (VR), blockchain technology, and digital convergence are the seven development directions of big data applications in the future


IOT is an important part of the new generation of information technology and an important development stage in the "information" era

its English name is "internetofthings (IOT)". As the name suggests, IOT is the interconnection of things

was put forward in 1999: it is a network that connects any object with the Internet through RFID (rfid+ interconnection), infrared sensors, global positioning system, laser scanner, gas sensors and other information sensing equipment according to the agreed agreement to exchange and communicate information, so as to realize intelligent identification, positioning, tracking, monitoring and management

scope of use IOT is widely used in many fields, such as intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire protection, industrial monitoring, environmental monitoring, street lamp lighting control, landscape lighting control, building lighting control, square lighting control, elderly care, personal health, flower cultivation, water system monitoring, food traceability, enemy investigation and intelligence collection

II. Smart city

smart city (English: smartcity) refers to the use of various information technologies or innovative ideas to integrate the constituent systems and services of the city, so as to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens

the specific definition of smart city is relatively broad. At present, the definition widely recognized in the world is that smart city is a city form supported by the new generation of information technology and under the next generation innovation (Innovation 2.0) environment in the knowledge society. It emphasizes that smart city is not only the application of the new generation of information technology such as IOT and cloud computing, but also the construction of user innovation and Urban sustainable innovation ecology characterized by open innovation, mass innovation and collaborative innovation

the scope of use is divided into ten smart systems, which are respectively: smart logistics system, smart manufacturing system, smart trade system, smart energy application system, smart public service, smart social management system, smart transportation system, smart health security system, smart housing service system and smart culture service system

III. augmented reality (AR) and virtual reality (VR)

ar augmented reality (AR) is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image, video and 3D model. The goal of this technology is to cover the virtual world on the screen and interact with the real world. This technique was proposed in 1990

ar application range AR technology is used in a wide range of fields, such as research and development of sophisticated weapons, aircraft, visualization of data models, virtual training, entertainment and art

because it can enhance the display output of the real environment, it has more obvious advantages than the VR reciprocating single screw extruder in the fields of medical research and anatomical training, precision instrument manufacturing and maintenance, military aircraft navigation, engineering design and remote control. The biggest feature is to realize the high filling processing of different materials

with the improvement of CPU computing power of portable electronic products, it is expected that augmented reality will be used more and more widely

vrvr is the abbreviation of virtualreality, which means virtual reality in Chinese. Virtual reality technology is a computer simulation technology that can create and experience the virtual world. It uses computers to generate an interactive three-dimensional dynamic scene. The simulation system of its physical behavior can immerse users in the environment

application range VR has not only been concerned in the field of computer image, but also involved in a wider field, such as video conference, network technology and distributed computing technology, and is developing towards distributed virtual reality. Virtual reality technology has become an important means of new product design and development. For example, real estate roaming (walking freely and watching freely in the virtual reality system, with strong impact, can make customers get an immersive and real experience, and promote the speed of contract signing), house viewing (during the rental and sale stage, users can get an immersive understanding of the project's weekly environment, spatial layout and interior design through the Internet), etc

IV. blockchain technology

blockchain technology, also known as distributed ledger technology, is an interconnected database technology characterized by decentralization, openness and transparency, so that everyone can participate in database records

was the basic technology of bitcoin at the earliest time. At present, it is being studied all over the world and can be widely used in finance and other fields

application scope: art industry, legal industry, development industry, real estate industry, application scenario analysis, logistics supply chain, public network service, insurance industry policyholder risk management, etc

meanwhile, blockchain technology will be applied to credit investigation, transaction security and information security in the financial industry. Financial data security, information privacy and network security are suitable for distributed blockchain technology. Blockchain can prepare high-quality biological capital composites in finance to form point-to-point digital value transfer, so as to improve the security of transmission and transaction

v. speech recognition

is a high technology that enables the machine to convert speech signals into corresponding text or commands through the process of recognition and understanding. It has long been a dream for people to communicate with the machine by voice and let the machine understand what you say. The image of China IOT school enterprise alliance compares speech recognition to "the auditory system of machines". Speech recognition technology mainly includes three aspects: feature extraction technology, pattern matching criteria and model training technology

application range speech recognition is the most popular application in mobile terminals, with voice dialogue robots, voice assistants, interactive tools and so on emerging in an endless stream

at present, Siri of Apple has been the leading application in foreign countries. Domestically, iFLYTEK, yunzhisheng, Shanda, Jietong Huasheng, Sogou voice assistant, Zidong interpretation, baidu voice and other systems have adopted the latest voice recognition technology, and other relevant products in the market have also directly or indirectly embedded similar technologies

in the past two decades, speech recognition technology has made significant progress and began to move from laboratory to market. It is expected that in the next 10 years, speech recognition technology will enter industries, home appliances, communications, automotive electronics, medical care, home services, consumer electronics and other fields

VI. artificial intelligence

artificialintelligence, abbreviated as AI. It is a new technical science to research and develop theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science. It attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system

application range machinetranslation, expert system, robotics, language and image understanding the quality of people and materials are all strictly controlled by the state. Genetic programming robot factory, automatic programming, aerospace applications, huge information processing, storage and management, performing complex or large-scale tasks that cannot be performed by synthetic life, etc

it is worth mentioning that the high-low refrigeration cycle of the machine adopts the inverse Karnaugh cycle. Translation is an important branch and application field of artificial intelligence. However, judging from the existing machinetranslation systems, the translation quality of the machinetranslation system is still far from the target of the system; The quality of machinetranslation is the key to the success of machinetranslation system. It is impossible to achieve the level of "faithfulness, expressiveness and elegance" in machinetranslation without knowing how the brain performs fuzzy recognition and logical judgment of language

VII. A trend of digital convergence

impact on the future is the effect of combining the above six trends

like 8.4 billion IOT devices, blockchain technology can be used to enhance security; Smart cities can generate massive data through IOT * and these data need to be analyzed by artificial intelligence; Virtual reality and speech recognition also need continuous learning through artificial intelligence. The development of these technologies is closely related and complementary, so digital convergence is an important trend
