Since then, smart homes have appeared, but there is no specific finished product. Until 1984 , United Technologies developed the first smart home, and it has become a popular product since then. Currently, smart homes use wireless signals to transmit information, avoiding the clutter, clutter, and wiring costs associated with using wired technology.

We live in the twenty-first century and enjoy all kinds of conveniences. Moreover, the Internet of Things, an emerging "big coffee", is indispensable, making our life from the Internet global village to today's Internet of Things. The application of technologies such as intelligent transportation, intelligent home, intelligent environmental protection, intelligent campus, and intelligent fire protection makes our life more convenient and our work more efficient, accurate, precise and precise.

1. Smart Transportation

At present, my country is vigorously building the future direction of transportation development - intelligent transportation system. ITS can make full use of the means of transportation in the world today to improve the efficiency of driving and transportation. Reduce traffic congestion and improve air quality. The BC849BLT3 adds an automatic electronic toll collection system (ETC for short) at the high-speed toll station, which enables the vehicle to complete the entire toll collection process while driving, and communicates with the on-board equipment (OBU) through the installation of roadside equipment (RSU) at the toll station. The ETC system can effectively reduce traffic congestion and ensure smooth traffic.

Highway manhole covers are one of the reasons for frequent traffic dangers. The theft of manhole covers happens from time to time. The development, development and use of Optech intelligent manhole covers cause manhole covers to fail, shift, noise, manhole covers and surrounding roads sink, and manhole cover materials are not uniform. Safety hazards caused by such problems also occur from time to time. Taking the bus is the most basic way for people to travel, and the bus card is more convenient. However, there are geographical restrictions on the public transport card, and it cannot be swiped across regions. With the development of the Internet of Things in my country, more and more places in the country have realized the cross-regional use of bus cards, which greatly facilitates people's travel. For example, the "All-in-One Card" issued in Shuozhou, Shanxi Province on August 20, 2017 can not only be used in Shuozhou, Datong, Jinzhong, Yuncheng and other places.

2. Smart Home

Since then, smart homes have appeared, but there is no specific finished product. Until 1984, United Technologies developed the first smart home, and it has become a popular product since then. Smart homes connect various smart devices in the home through Internet of Things technology, automatic control systems, and network systems. Currently, smart homes use wireless signals to transmit information, avoiding the clutter, clutter, and wiring costs associated with using wired technology. Now, the more mainstream wireless methods in the smart home industry are ZigBee, WiFi, Zwave, Bluetooth and so on. Compared with traditional homes, smart homes not only have traditional living functions, but also provide information interaction functions. With the help of the Internet of Things technology, users can easily realize a series of actions such as lighting control, electrical control, and security monitoring system debugging with a mobile phone or a remote control. It is the ultimate goal of smart home to enable users to have a comfortable, safe, environmentally friendly and convenient experience.

3. Smart environmental protection

Intelligent environmental protection is to place equipment that can collect and transmit information in various environments, and integrate information with the help of Internet of Things technology, supercomputers and cloud computing to better manage environmental management and pollution sources. IBM will introduce the concept in 2009. The intelligent environment platform is mainly divided into two parts: data acquisition hardware, which collects various environmental data and uploads these data to the server side. The commonly used transmission networks include wireless ZigBee technology, GPRS, and 3G communication technology. Second, the data center software system will process and analyze the information uploaded to the server. Anomalies can be notified to employees in a number of ways. For example, some products can be used for ground water quality detection, such as the IMS intelligent fault diagnosis and management system, which can use the Internet of Things technology to grasp the water quality status of each monitored water area in time. Timely early warning of water pollution. Compared with traditional environmental pollution monitoring methods, it has obvious advantages: long warning time and high accuracy, which can promote environmental protection work.

4. Smart Campus

With the help of the Internet of Things technology, various resources such as teachers and campus funds on campus can be integrated and used in a unified and efficient manner, so as to improve the perception ability of various departments in the campus, and promote the interconnection between the campus information management system and the real world, so that all aspects of the campus can be integrated and used. The application is deeply intelligent, integrates resources, saves costs, makes the management and maintenance of terminal equipment more convenient, and better serves campus users. At the same time, through the Internet of Things technology, it is easy to solve the problem of campus security. When spending on campus, you can use your mobile phone to swipe your card. You can use the campus card for identity recognition, and you can use the card to solve problems such as book lending and access control. The use of Internet of Things technology in primary and secondary schools can enable parents to keep abreast of students' arrival, departure time, and recent learning conditions. For example, the school newsletter launched by China Mobile greatly facilitates the supervision and education of students by parents and teachers.

5. Intelligent fire extinguishing

It is a high-tech fire protection system integrating Internet of Things technology, global satellite positioning system, wireless communication system, GIS and other high-tech. It realizes the functions of alarm, timely disposal of fire, and evacuation of the masses. Record and analyze the fire situation, accurately record the alarm time and location, and make efficient integration arrangements for the police force. After receiving the alarm to understand the situation, the system can immediately display the electrical circuit, water pipe, gas pipeline, etc. Lines can minimize fire hazards and losses, break information barriers between fire protection systems, make fire protection resources more complete and rationally use, and promote the transformation of fire protection work from traditional passive single to active comprehensive.

Epilogue

As an emerging technology, the Internet of Things is also a comprehensive technology, an important productive force that promotes the rapid development of the world economy, and the direction and biggest driving force of the latest industrial revolution. We must firmly seize the development opportunities and promote the faster development of the Internet of Things with new regulations.
