The Internet of Things, the Internet of things connected to it, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Second, its client extends and extends between items and items. Information exchange and communication. The Internet of Things is the third wave of information industry after the computer, Internet and mobile communication networks, and is listed as one of the strategic emerging industries that the country focuses on.
In recent years, with the continuous decline in the price of hardware such as chips and sensors, and the innovation and progress of communication networks, cloud computing and intelligent processing technologies, the Internet of Things has ushered in a period of rapid development. It is predicted that by 2020, the world's physical Internet interconnection business will reach 30 to 1 compared with the human-to-human communication business, and the Internet of Things is regarded as the next trillion-level communication business.
I. Overview of the Internet of Things Industry
The process of information exchange and communication between objects in the Internet of Things consists of three levels: one is the sensing layer, that is, the information of the object is acquired anytime and anywhere by using RFID, sensors, two-dimensional codes, etc.; the second is the network layer, through various telecommunication networks. Integration with the Internet, the object information is accurately transmitted in real time; Third, the application layer, the information obtained by the sensing layer is processed to realize the practical application of intelligent identification, positioning, tracking, monitoring and management.
The three-tier architecture of the Internet of Things: the perception layer, the transport layer, and the application layer
Second, China's Internet of Things market size forecast
In 2009, the United States, the European Union, and China raised the IoT development policy. Today, the Internet of Things has experienced a period of rapid development. Traditional enterprises and IT giants have laid out the Internet of Things. The Internet of Things is accelerating in many areas such as manufacturing, retail, service, and public utilities. The Internet of Things is on the eve of massive explosive growth.
In 2015, the global IoT market reached US$62.4 billion, a year-on-year increase of 29%. By 2018, the global IoT device market is expected to reach US$103.6 billion. The compound growth rate will reach 21% from 2013 to 2018. The number of new IoT devices connected in 2019 will increase from 1.691 billion in 2015 to 30.54. Billion Taiwan.
The scale and growth rate of the global Internet of Things market in 2013-2018
At the same time, more and more items and devices are being connected to the Internet of Things. At present, the number of IoT devices has reached 4.9 billion, which will increase by 30% in 2016. By the end of the year, the number of devices accumulated in the global IoT will reach 6.392 billion. By 2020, the number of IoT devices used worldwide will grow. To 20.8 billion. It is expected that the number of IoT devices will exceed the total of PC, tablet and smartphone stocks by 2018. Among them, consumer wearable devices will continue to dominate, for sports and fitness, recreation, smart switches, medical health, remote control, identity authentication, glasses, running shoes, watches, bracelets, rings and other forms of wearable devices. Infiltrate people's lives and bring more convenience.
New access to global IoT devices in 2003-2019 (100 million units)
Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
