The era of big data has arrived. The extensive application of sensors, RFID, computers, cameras and other devices, as well as the rapid popularization of mobile terminals such as smart phones, tablet computers and wearable devices, have promoted the rapid growth of global digital information. The Internet of Things is an important source of big data. With the popularization and application of the Internet of Things in all walks of life, huge amounts of data are generated on the Internet of Things every second.
Data is resources and wealth. Big data analysis has become a key element of business, and data-based analysis, monitoring and information services are becoming more and more common. In all walks of life, there are more and more data-driven enterprises, and they must absorb and analyze data in real time to form correct judgments and decisions. Big data is becoming a new commanding height in the IT industry, and the Internet of Things based on applications and services will promote the wider application of big data.
Due to the unstructured, fragmented and spatio-temporal characteristics of Internet of Things data, new data storage and processing technologies are needed. And big data technology can support the deeper application of massive data in the Internet of Things. The Internet of Things helps to collect a large amount of data from the perception layer, the transport layer, the platform layer and the application layer, and then transmit these massive data to the cloud computing platform for analysis and processing. The big data processing process generated by the Internet of Things can be summarized into three basic steps: data collection, data storage and data analysis. Data collection and storage are basic functions, and the real value of the era of big data lies in data analysis. The challenge of IOT data analysis is to integrate new IOT data with existing databases.
The application space of big data in the Internet of Things is vast, and the combination of big data and the Internet of Things is full of infinite possibilities. With the joint application of Internet of Things, Internet, mobile Internet, intelligent terminal, large-screen display system and cloud computing platform, Internet of Things big data can help people build intelligent monitoring model, intelligent analysis model, intelligent decision-making model and other applications, profoundly changing people's lives.
Smart city is the largest application field of Internet of Things, and the fields of Internet of Things such as smart agriculture, smart home, smart logistics, video information processing in smart security, real-time traffic guidance in smart transportation, and environmental monitoring in smart environmental protection are all applications of big data. For example, environmental monitoring, sensors use the Internet of Things to transmit information to the Internet platform or mobile Internet platform to monitor environmental changes in real time. Through the environmental monitoring model, the massive environmental data collected are analyzed, and the abnormal points of environmental index changes are found, which helps the environmental protection department to predict the environmental changes in a certain place in advance, and if the environmental index deviates from the normal index value, an environmental pollution warning is issued. Intelligent manufacturing or "industrial Internet" is a classic case of the wonderful combination of big data and Internet of Things in the future. In terms of industrial applications, the combination of big data and the Internet of Things will also "spark". For example, postal services can be transformed into "postal Internet of Things" through big data and Internet of Things. The postal network can be equipped with low-cost sensors, which greatly enhances the ability of postal operators to collect valuable data. This huge new data source can help postal operators improve their operational capabilities, improve customer service, create new products and services, and support more efficient decision-making.
The value of the Internet of Things lies in its data. The Internet of Things has brought about breakthrough technological progress, but the problem of managing big data has become more prominent, which requires the full support of relevant information and communication technologies. For example, the generation, capture, transmission and analysis of data need a fast, stable and reliable WAN, and wireless communication technologies such as 3G, 4G and WiFi should be continuously optimized to support the comprehensive improvement of information perception, transmission, information processing and storage capabilities of the Internet of Things and sensor nodes.
The Internet of Things generates big data, and big data helps the Internet of Things. The trend of big data triggered by the Internet of Things will also promote the integration and development of new information and communication technologies such as cloud computing.
