With the rapid development of science and technology, the Internet of Things is no longer a new word, especially in the past two years. If four years ago, Premier Wen Jiabao put forward "Perception of China" in Wuxi, which sounded the rallying cry of China's Internet of Things industry, now is the time to charge.
Even if you haven't heard of the Internet of Things, you've been trapped in its "encirclement circle": you come out of the subway, see shared bicycles, scan code and unlock using the Internet of Things technology; when your ID card and bank card are embedded with chips, the application is the most basic RFID technology of the Internet of Things (wireless radio frequency technology); when you are full of expectations. When you look at Baby's logistics trend on Taobao, it's a whole set of Internet of Things system of express company that silently supports behind it; and when you open the "sweep-and-sweep" function of Wechat in supermarket to scan the price tag, you are witnessing Tencent, an Internet giant, marching towards the Internet of Things.

Today, the Internet of Things is quietly changing our lives. The promotion of smart home and the construction of smart city all reflect its application.
_2013 can be called the first year of the Internet of Things in China. In this year, the new vocabulary of "Internet of Things" appeared in the government work report for the first time; industrial parks in various provinces and cities sprang up like mushrooms on this high-speed train for the future; Haier, which has been at the bottom of the industrial chain "striving for the upper reaches", took the lead in issuing the first "Internet of Things refrigerator"; The Internet of Things Congress is in full swing, and the golden future is reflected on everyone's face.
Over the past three years, trillions of market valuations and science fiction-like future prospects can no longer excite people. The Internet of Things has disappeared from the hot vocabulary list, but is entering everyone's life "silently": it is the monthly value-added package service of China Mobile's customer service representatives. App app, which tracks sleep quality on the iPhone, is a smart home experience hall that appears at the entrance of the community...
_China Internet of Things Congress has held four sessions. From the first conceptual discussion, the second technical debate to this year's application, it witnessed the process of the Internet of Things rooting in China from the castle in the air to the ground in the past three years. From the initial concept of nihility to the present development path is becoming increasingly clear, the Internet of Things is getting closer and closer to us.
_As an all-encompassing network for information exchange and communication between things, the Internet of Things is called the third wave of information industry after computers and the Internet. Thousands of sensors are implanted into each object to make it have "ears, eyes, mouth, nose" like human beings, to know cold and heat; to transfer and exchange information between objects through wireless communication technologies such as WiFi and Bluetooth; and finally, to make all kinds of application scenarios for human use and service. In short, the sensor layer, the network layer and the application layer have woven the most ambitious network in history.
With the progress of technology, in recent years, the development of hardware in the Internet of Things has made rapid progress in the direction of miniaturization and low cost. At present, a chip with sensing and computing capabilities can achieve 2 square millimeters, smaller than an ant, and the cost has been controlled below $1, which was impossible five years ago.
Zhuolianwei is also the first company in China to provide components supply, design assistance and technical support services for wireless products to customers. It has cultivated the Internet of Things component market for more than ten years, and its supply is stable, which is well recognized by its partners.
Looking back at the global Internet of Things, although the technology of sensor layer has been basically mature as early as more than a decade ago, due to the lack of standard and unified short-distance, low data transmission rate wireless communication protocol between sensors, it is only an independent "information island". However, in recent years, ZigBee, Z-Wave and other major wireless communication protocol alliances have formed a tripartite trend, which to some extent paves the way for the "thing-to-thing connection". Among them, the International ZigBee Alliance established in 2011 has more than 420 members, and more than half of the world's top 500 enterprises are included.
With the popularity of smart phones and the development of the Internet, the rise of smart home has been promoted. The close connection between the Internet of Things and mobile communication has promoted the development of smart home, photosensitive operation, temperature and humidity adaptation and other applications in Android. So there is a saying in the industry that the opportunity for the explosive growth of the Internet of Things is the smart terminal + mobile Internet.
Today's smart home, in this form, appears in front of the public, mobile phone, mobile device control + Mobile Internet control. Intelligent life applications of the Internet of Things are flourishing everywhere. Intelligent wearing hand-ring watch, Bluetooth keyboard and mouse, anti-loss device, indoor positioning, smart home, wireless charging, smart door lock.
