The application and development of the Internet of things technology

Marisa D

Abstract

Internet of things is considered through monitoring, analysis and control of

network information technology, the extension of human perception of control ability

has huge potential. Iot research work has been carried out. A lot of Iot demonstration

system was also developed, and has made remarkable application effect. But at the

same time, the current development of the Internet of things is also facing some

fundamental problems: the Internet of things has what special requirements must be

met? What phase are you in the Internet of things technology? Where is the

development direction of Internet of things? It is worthwhile to explore these issues.

This paper reviews the development of the Internet, and according to the experience

of the development of the Internet, analyzes the present situation of Internet of things

and Internet of things present in the "content - machine connected to the local

small-scale network stage, its development direction should be connected to open net

of numerous small" net ", namely the "Internet of things". Based on this idea, called

WInternet Iot design, and introduces the overall architecture, working mode and

protocol system, and also discusses the several other issues worthy of further study.

1 Introduction

In recent years, the development of the Internet of things has been attached great

importance to, academia, industry, the government to give great attention to the

development of the Internet of things. Internet of things is considered can connect

hundreds of millions of physical world objects, through monitoring, analysis and

control of network information technology, the extension of human perception control

ability has huge potential. Iot research work has been carried out. A lot of Iot 物联网技术的应用及发展研究最新外文文献翻译

demonstration system was also developed, and has made remarkable application

effect. But at the same time, the current development of the Internet of things is also

facing some problems, especially all kinds of Internet of things generally are

connected by "-" in the form of "network", although the implements of all kinds of

physical objects in the local scope - machine is linked together, but different "net"

resource sharing between the perception and control equipment. And because of the

existing "- machine connected to the network is generally based on the special

agreement, adapt to the need of the professional custom, cause a physical network is

not open, hard to connectivity. To realize all kinds of network connectivity should be a

Iot of development trend.

2 Internet development history and experience

2.1 Electronic equipment network systems

In the 19th century to early 20th century, electronic equipment network of

prototype has emerged. As the time of the telephone network, cable network, and

other various types is private network system. Now in retrospect, these networks have

been gradually replaced by the Internet; its reason is worth thinking about. Analysis of

the network system can be found early, they generally have the following features:

(1) Vertical integration, tightly coupled

The network system hardware, software and operation of the upper application

mostly belong to an owner. Most of the various components of the integration in the

network system is independently by the owner internal personnel, network in each

part of the tightly coupled system.

(2) The proprietary protocols to exchange

In the network system of internal communication protocol is often according to

the specific needs of each owner, in order to better the optimization and use of all

kinds of equipment components are designed. Different owners of intellectual

property rights and interests protection often will deal core part try to conceal,

difficult to communication between different network systems. This method of

"vertical integration, proprietary protocols" to satisfy the various network system of

the optimization of resources and interests of the owner to protect specific needs, but 物联网技术的应用及发展研究最新外文文献翻译

also directly led to the early electronic equipment network problems.

(3) Resource sharing difficult

Because every electronic device network system is generally adopts the way of

"vertical integration" structure, the network system in all kinds of electronic

equipment and software are also often can only be used for the network users of the

system. For example in the early days of the telephone network system, multiple

phone companies have independent laid their phone lines, set up relevant telephone

switching equipment, a relatively independent telephone network. Different lines and

equipment cannot be Shared between the telephone network, caused the repeat

purchase, resource sharing difficult.

(4) Function to replicate

Another problem is that in the different network system to repeat the same or

similar functions, such as the telephone network signaling in the instruction and the

signal coding implementation. Features to replicate directly lead to two results: one is

each owners are required for the design and implementation of general agreement and

equipment, but due to the limitation of the technical strength of a single owner, will

inevitably extend network independently design and development time; Second, under

the limit of time and personnel, the realization of function module final quality more

or less is not ideal. If different owners to cooperation, complementary advantages,

functional modules will not only greatly shorten the development time, its quality will

improve the quality and technology evolution speed will also increase.

3 Internet of things present situation and the development direction

3.1 The development of Internet of things

Iot technology emerges in various fields has also been a high degree of attention,

many of the Internet of things application demonstration is put forward and the

construction, especially in environmental monitoring, traffic control, disaster

emergency, etc. The application of these systems has also made certain achievements.

But at the same time, we can also see the current before the development of the

Internet of things is with the Internet electronic networks have similar features,

especially the "vertical integration" and "special deal". Currently, many of Iot system
