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. Internet of things, smart city, augmented reality (AR) and virtual reality (VR), speech recognition, artificial intelligence are the future application direction of big data.

Internet of things

The Internet of things is not only an important part of the new generation of information technology, but also an important development stage of the "information" era.

Its English name is "Internet of things (IoT)". As the name implies, the Internet of things is the Internet of things connected to things.

In 1999, it was proposed that through radio frequency identification (RFID) (RFID+ Internet), infrared sensors, global positioning system, laser scanners, gas sensors and other information sensing devices, according to the agreed protocol, connect any object with the Internet for information exchange and communication, so as to achieve intelligent identification, positioning, tracking, monitoring and management of a network.

smart city

The specific definition of smart city is relatively extensive. at present, the internationally accepted definition is that smart city is the urban form in the environment of new generation information technology support and next generation innovation (innovation 2.0) in knowledge society. It emphasizes that smart city is not only the application of new generation information technology such as Internet of things and cloud computing, but also the application of innovation 2.0 methodology oriented to knowledge society. To build an urban sustainable innovation ecology characterized by user innovation, open innovation, mass innovation and collaborative innovation.

AR

Augmented reality (Augmented Reality, referred to as AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos and 3D models. The goal of this technology is to set the virtual world in the real world and interact on the screen. This technology was proposed in 1990. Rabbit dynamic ip circuit is good, the speed is fast and stable.

VR

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

Speech recognition

Speech recognition technology is a high technology that allows the machine to transform the speech signal into the corresponding text or command 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 are saying. The image of the school-enterprise alliance of the Internet of things in China has to compare speech recognition to a "machine auditory system". Speech recognition technology mainly includes feature extraction technology, pattern matching criterion and model training technology.

artificial intelligence

Artificial intelligence (Artificial Intelligence), abbreviated as AI. It is a new technical science that studies and develops theories, methods, technologies and application systems used to simulate, extend and expand human intelligence. Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence. research in this field includes robots, language recognition, image recognition, natural language processing and expert systems.
