One 、 You know, long distance love artifact -- “ Space kissing machine ” Do you ？

As 《 The big bang theory 》 The lowest educated person in the group of four , Howard With his rich expression 、 Yelling at his mother and all kinds of crooked ideas to maintain his position in the audience's mind . It's impossible to invent seriously , Never in my life . As him “ imagination ” One of ,“ Space kissing machine ” Can be said to be the most practical invention ！ The invention uses two sensors placed in two oral like devices , Then hold one of the devices and touch it with your mouth , The other can feel the touch of the other person's lips ！ Although it's a little bit ……, But it really works ！ After all Leonard It's not a trial of integrity , And then he and his Indian girlfriend became the first beneficiaries .

As an artifact of long-distance love ,“ Space kissing machine ” It perfectly embodies the concept of the Internet of things ： On the basis of the Internet , Extend and extend the client to things and things 、 The connection between things and people . In the mode of Internet of things , All items are connected to the Internet , And communication and scene linkage .

More technically , The Internet of things is the extension of the Internet . The Internet goes through computers 、 Devices such as mobile terminals connect participants , The formation of a new way of information exchange . And the Internet of things is through sensors 、 chip 、 Wireless modules connect devices . therefore , The number of devices connected to the Internet of things is huge , Because in theory , All devices are networked .

Two 、 Three elements of the Internet of things ： What should the complete Internet of things look like ？

although Howard Of “ Space kissing machine ” This is a good interpretation of the prototype of the Internet of things , however , It is not a complete Internet of things . Because the formation and control of the Internet of things depends on the following 3 Elements .

• Device networking capabilities ： Through different network protocols and communication standards , Realize the connection between the device and the control end , And perform intelligent operations .

• Cloud ： Provide monitoring 、 Storage 、 Data services such as analysis , And protect the business data security of customers .

• Control terminal ： Receive data information and control commands from devices and cloud , The control end is usually App、 Cloud intelligence 、 Other equipment （ for example Google Home,Amazon Echo etc. ）.

“ Space kissing machine ” It's just the initial realization of the networking capability of the device , Let two people in different spaces , Can realize touch interaction based on sensors . Let's suppose a scenario , If “ Space kissing machine ” Be able to mass produce （ Congratulations on Howard Products are on sale ！）, that Howard A cloud is needed to store and analyze all terminal devices （ For example, geographical location 、 Electricity consumption 、 Temperature and humidity, etc ）. And as a user , Out of the pursuit of product capabilities , In addition to the basic requirement that the product can be more beautiful , More need to be able to have panel or voice control functions , In order to be able to control the equipment more accurately .

3、 ... and 、 The Internet of things DCM framework ：Device、Connect、Manage

In the architecture of the Internet of things , Can be divided into DCM Three levels of logic （ Here's the picture ）.

• Perception layer （Device）： Belong to DCM The first layer of Architecture , Responsible for overall perception , Using RFID 、 QR code 、 Sensors, etc 、 Capture 、 Measurement technology can collect and obtain the information of objects anytime and anywhere . namely “ Space kissing machine ” The device terminal of .

• The network layer （Connect）： Responsible for reliable delivery , By connecting objects to information networks , Relying on communication networks and protocols , Realize credible information exchange and sharing . namely “ Space kissing machine ”“ After mass production ” Storing data

• application layer （Manage）： Responsible for intelligent processing , Analyze and process massive perceptual data and information , Realize intelligent decision and control .

Four 、 Industry Overview ： The global The Internet of things “ stride forward singing militant songs ”, AI+IoT Fusion landing

• The number of connections is soaring

AIoT Concept in 2018 year rise , According to iResearch's Industry Research Report , expect 2025 year China IOT The number of network connections is near 200 One hundred million , Everything wakes up 、 Massive connectivity will drive all walks of life on the smart road .

​​​​​​​

According to international data IDC It is estimated that , To 2020 The Internet of things (IOT) will be produced worldwide in 1.46 Trillions of dollars worth .

• A mixture of fanaticism and prudence 5G Technology development

5G The technology is 2019 One of the hot topics of the year .2019 year , Issued by the Ministry of industry and information technology of China 5G Temporary business license , Open the 5G First year .

Organize according to standards 3GPP Work progress of , What has been done so far 5G The standard focuses on enhanced mobile broadband （eMBB） scene .2019 to 2020 year ,5G The first commercial scene also focuses on this , but eMBB This scene is more for the mobile Internet , It's still people to people communication , Limited support for IOT applications . The other two scenarios have low delay and high reliability （uRLLC） Communicating with large machines （mMTC） The work of standardization for is still not finished , Its commercial push will be slower , And the technology of these two scenarios is 5G Core support for the domain of IOT business .

• cloud 、 edge 、 End collaboration ,AI Integration with the Internet of things will be further implemented

In the application scheme of Internet of things , Cloud Computing 、 Terminal computing and edge computing are a collaborative system , According to the user scenario 、 Resource constraints 、 Dynamic adjustment of real-time business with , Form reliable 、 Low cost applications . Cloud computing vendors 、IT manufacturer 、 The concept of edge computing in different roles such as operators and vertical industry manufacturers 、 There are different understandings of edge node location and edge computing power , But in the face of the Internet of things solution to achieve cloud 、 edge 、 End collaboration has reached a consensus .

Judging from the development and accumulation in the past few years ,AI It has been integrated at multiple levels of the Internet of things , On the terminal side AI、 Marginal side AI、 Cloud AI The capability architecture is in place . Some famous Chinese enterprises , For example, Hikvision 、 Kuang depending on science and technology 、 Horizon and others have released platforms and products related to the Internet of things , Expect to pass AI+IoT Achieve more business development .
