The Internet of Things is an important part of the new generation of information technology and an important development stage in the "informatization" era. The Internet of Things is widely used in the integration of networks through communication perception technologies such as intelligent perception, recognition technology and pervasive computing. It is known as the third wave of the development of the world's information industry after computers and the Internet. The Internet of Things is the application expansion of the Internet. The Internet of Things is not so much a network as it is a business and an application. Industry fields where the Internet of Things technology is applied abound. It is quietly integrated into our lives:
The traditional power grid adopts a relatively centralized closed management mode, which is relatively inefficient. Therefore, every year, the traditional power grid produces amazing waste in the process of power generation and transmission. Due to the uneven distribution of energy, long-distance power transmission causes huge power transmission losses. On the other hand, traditional power grids that lack smart grid load balancing or current monitoring are even more terrifying every year, enough for the three countries of Germany, India, and Canada for a full year. Using the Internet of Things technology to improve and optimize the system on the original power grid, data can be measured in the three links of power generation, power transmission and power consumption, and then a data link can be established on the network to achieve the effect of data interoperability and effective monitoring. Among them, the adaptive smart grid can automatically coordinate various elements in the grid and make deployments to achieve more efficient power supply and distribution effects. Electricity users can query electricity consumption data such as electricity consumption at any time through the smart grid system, and improve their electricity consumption habits based on the information they have learned. Power companies can use smart grid systems to automate energy metering and data collection and sorting, and get rid of the complicated work that requires a lot of manual work. Through real-time monitoring, power quality monitoring can be achieved, peak loads can be reduced, and various energy sources can be integrated and deployed to achieve an integrated and efficient management effect. . The government and society can use the smart grid system to know the supply and demand status of power resources in a timely manner and decide how to arrange peak-shift power consumption, save energy and protect the environment, and ultimately achieve more efficient, more flexible, and more reliable grid operation and management, thereby achieving energy saving and reduction. The purpose of platooning and sustainable development.
2. Smart logisticsLogistics is the process of the physical flow of goods from the supply place to the receiving place. According to actual needs, the functions of transportation, storage, loading and unloading, packaging, circulation processing, distribution, and information processing are organically combined to achieve user requirements. The traditional logistics model basically meets the requirements of logistics. However, with the further development of the economy and the increasing requirements of users for modern logistics, the limitations of the traditional logistics model are becoming increasingly apparent: production, procurement, transportation, warehousing, distribution and other links are isolated. , Lack of collaboration, unable to track the status of goods in real time, and may cause inventory pressure, capital pressure, relatively high costs, and low efficiency.
Intelligent logistics benefits from the support of Internet of Things technology, realizing real-time monitoring, real-time analysis and processing functions in the links of procurement, transportation, warehousing, and distribution. More importantly, for users, intelligent logistics can provide a search engine to query the status of goods in a timely manner, and quickly deliver them to users on the basis of ensuring that the quality and quantity of the goods are complete. For goods manufacturers and transportation companies, intelligent logistics can optimize the logistics chain of raw material procurement, semi-finished products transportation and distribution, and delivery of finished products to user terminals, helping companies determine the location of raw materials, optimize procurement locations, formulate inventory allocation strategies, and achieve supply-to-user logistics Seamless supply chain. This can improve corporate control, while reducing inventory pressure, reducing capital and time costs, improving customer service, and enhancing corporate competitiveness.
3. Intelligent transportationWith the enrichment of material life after the reform and opening up, wealthy people began to pursue a high-quality life, so they turned their attention to private car consumption. Therefore, the people's demand for automobile travel is increasing. In recent years, my country has become the largest country in the production and sales of automobiles. However, the progress of infrastructure and traffic management is far from keeping up with the explosive growth of car ownership, which has brought many problems to society such as traffic jams and traffic accidents.
To reduce traffic jams, in addition to repairing roads, intelligent transportation systems can maximize the effectiveness of transportation infrastructure. Through the Internet of Things, intelligence is injected into the entire transportation system of the city, including streets, bridges, intersections, signs, signals, and tolls. By collecting traffic information such as digital video surveillance, vehicle-mounted GPS, smart traffic lights, and mobile phone signaling, road condition information can be obtained in real time and the vehicle can be located, thereby optimizing the itinerary for the vehicle, alleviating traffic congestion, and choosing a parking location. The traffic management department can use the Internet of Things technology to intelligently dispatch and manage public transportation such as taxis and buses, intelligently induce private vehicles to control traffic flow, detect, analyze, and record violations of traffic rules, and take measures for those entering and exiting highways. Vehicles are seamlessly detected, identified, and automatically charged, ultimately improving traffic capacity. Currently in Shanghai, data collected by road sensors in real time and sent to the model of the control center have reached 90% accuracy in predicting future traffic conditions. In the future, through the Internet of Things technology, vehicles will be connected to the network, making urban transportation more flexible. Therefore, intelligent transportation will reduce congestion, reduce fuel consumption and carbon dioxide emissions, improve people's travel, and improve people's quality of life.
4. Smart homeSmart home is divided into two concepts: broad sense and narrow sense.
Smart home in a narrow sense refers to all kinds of consumer electronic products, communication products, information appliances and smart homes that communicate and exchange data through the Internet of Things to realize the "interconnection" between various electronic products in the home network, so as to realize anytime, anywhere Control of smart devices. For example, if the home environment system detects that the indoor humidity is too high, it will cooperate to start the air conditioner to take dehumidification measures; if the concentration of oil fume in the kitchen is too high, it will start the range hood; if the weather suddenly rains or there is too much noise outside, it will automatically close the windows; The solar radiation is larger, it will automatically close the curtains.
The broad sense of home furnishing refers to the construction of smart communities, which is mainly a community network system centered on information networks, monitoring networks, telephone and television networks, through efficient, convenient and safe network systems to achieve a high degree of information integration and sharing, and to achieve automation of the environment and electromechanical equipment , Intelligent monitoring. Smart communities can carry out HVAC, water supply and drainage monitoring, public area lighting, parking management, background music and emergency broadcasting and other property management through the community integrated network, as well as access control systems, video surveillance, intrusion alarms, automatic fire alarms, and fire linkages. Security precautions.
The construction of a smart community is a process of continuous improvement and perfection. With technological progress and my country's continuous deepening of the management system reform, the current three independent Internet, telephone and television networks have gradually merged into a unified comprehensive network, which further improves the digital level of the community, and realizes the sharing of information resources and the optimized configuration of equipment.
