Internet of Things technology is no longer a new term along with the rapid development of technology, but it is quietly changing our lives. The promotion of smart homes and the construction of smart cities all reflect its application.
If four years ago, when Premier Wen Jiabao’s “perceived China†proposed in Wuxi blew the assembly number of the Chinese Internet of Things industry, then it is time to charge.
Even if you haven't heard of the Internet of Things, you are already immersed in its "encirclement": your ID card is populated with the most basic RFID (radio frequency technology) of the Internet of Things; when you look forward to seeing it on Taobao When the logistics of the baby goes, it is the complete set of IoT system of the courier company behind the silent support; and when you open the WeChat “sweep†function in the supermarket to scan the price of the commodity price tag, you are witnessing the Internet giant of Tencent. Advance to the field of Internet of Things.
Technology and standards are "waterful"
2010 can be called China's "first year of the Internet of Things." In this year, the new term “Internet of Things†appeared in the government work report for the first time; the industrial parks of various provinces and cities have been squeezing on the high-speed trains that open to the future; they have been at the bottom of the industrial chain and “strive for the upper reachesâ€. Haier took the lead and released the first "Internet of Things Refrigerator"; China's first Internet of Things conference was on the scene, and the golden future was reflected in everyone's face.
Three years have passed, and the market valuation of the trillions of dollars and the general picture of the sci-fi film can no longer make people feel the tide. The Internet of Things disappears from the popular vocabulary list, but it is entering each one in a silent way. Human life: It is the monthly value-added service in the mobile phone representative of China Mobile. It is the APP application for tracking sleep quality on the iPhone. It is the smart home experience hall that appears at the door of the community...
The China Internet of Things Conference has been opened for four sessions. From the first concept discussion, the second technical dispute to the application of this year, witnessed the three years of the Internet of Things in China from the castle to the ground. From the original illusory concept to the increasingly clear path of development, the Internet of Things is getting closer and closer to us.
As an all-encompassing network that realizes information exchange and communication between objects, the Internet of Things is called the third wave of the information industry after computers and the Internet. Thousands of kinds of sensors are implanted into each object to make them "ear, eye, mouth, nose" like human beings, knowing the cold and knowing the heat; and transmitting information between objects through wireless communication technologies such as WiFi and Bluetooth. Exchange; finally, in all kinds of application scenarios, let all things be used for people and serve people. In a nutshell, the sensor layer, the network layer, and the application layer trinulate the most ambitious network ever.
With the advancement of technology, the development of IoT hardware has progressed rapidly in the direction of miniaturization and low cost. At present, a chip with sensing and computing functions can already achieve 2 square millimeters, which is smaller than an ant, and the cost has been controlled below 1 US dollar, which was impossible to achieve 5 years ago.
Looking back at the global Internet of Things, although the technology of the sensing layer has been basically matured more than a decade ago, due to the lack of standard uniform short-distance, low data transmission rate wireless communication protocols between sensors, it is only one. Connected "information islands." However, in recent years [industrial electrical network-cnelc], ZigBee, Z-Wave and other major wireless communication protocol alliances have formed a standing position, to a certain extent equal to paving the way for "throwing things." Among them, the number of international ZigBee alliances established in 2011 has exceeded 420, and more than half of the world's top 500 companies are included.
In recent years, it has also become a process of “popularization†of smartphones and mobile Internet at a faster rate than PCs and the Internet. Nowadays, a hundred-dollar smartphone can run the most advanced Android operating system, equipped with various sensing devices such as camera, GPS, gyroscope, etc., making it a low-cost control terminal for the Internet of Things, and AppStore, GooglePlay. It also gives Internet of Things applications the opportunity to appear in front of hundreds of millions of consumers.
"At present, there are many applications of temperature, humidity, sound, fingerprint, barcode, level and compass on the Android platform. The downstream industries of peripheral industries such as peripherals and equipment have also been fully developed, and there is a sufficient combination with the Internet of Things. Liu Yun, vice president of Google Global, said.
Liu Yun believes that the Internet of Things and mobile phone communication will be closely linked, including smart home, light operation, temperature and humidity adaptation applications will be developed in Android. Therefore, there is a saying in the industry that the explosive growth of the Internet of Things is the smart terminal + mobile Internet.
The output chain is on the rise
The Internet of Things has become a "magic stick" of stone and gold, and every "grasshopper" in the industrial chain has followed "the chicken and the dog". Many of the former RF industry, security industry, Internet industry, and software industry have all changed themselves, and they have labeled the Internet of Things. The Internet of Things has also become a "strong-hearted agent" for stimulating the sluggish A-share market. When the policy has a "wind and roll", the Internet of Things concept stocks such as Yuanwang Valley, New World, Eastcom Peace, and Hengbao will sound up. one slice". On February 17 this year, the State Council issued guidance on the development of the Internet of Things, and various IoT concept stocks have soared.
The overall supplier will account for about 20% of the overall industrial value. The pipeline provided by the telecom operators accounts for about 20% of the overall industrial value, and the remaining 60% of the market value is shared by the application.
The industry chain is classified by value, and the value of hardware manufacturers is small. When sensor chip manufacturers and communication modules are mentioned in the downside of traditional communication services, operators have been trying to find the next "ticket" to tomorrow, moving Internet, cloud computing, big data... They are betting on every emerging field, and the Internet of Things will not miss it. Operators who play a key role in the industry chain are not willing to fall into the "pipeline" of the Internet of Things, but hope to become an industry integrator of all parties.
As the earliest telecom operator in China to invest in IoT research and application development, China Mobile has invested more than 1 billion yuan in the field of Internet of Things, forming more than 30 mature products such as China Unicom, Yijutong, Chewutong and Elevator. And the application, the service user scale reached 50 million, and initially achieved the goal of scale application.
