Application model
According to actually divided to three basic application model:
the objects Smart label : Through two-dimensional code, RFID and other technical identifying the particular objects, to distinguish the individual, such as in daily life , we use a variety of smart cards, bar code label the basic purpose is to obtain identification information; by the way through the smart label also can obtain expansion information of the object, such as amount on the smart card, the URL and name contained in the two-dimensional code contained and so on.
Environmental monitoring and object tracking: Using a various of sensors and a wide range of sensor networks, can achieved the real-time status acquisition and monitoring of specific object, such as using the noise detectors to monitor noise pollution which distributed in the urban area, through carbon dioxide sensors monitoring the atmosphere In the concentration of carbon dioxide, through the GPS tag tracking vehicle location, through the traffic junction of the camera to capture real-time traffic flow.
Intelligent control of the object: Internet of things are based on the cloud computing platform and intelligent network, can obtain the data to make decisions according to the sensor network change the behavior of the object control and feedback. For example, according to the strength of the light to adjust the brightness of the street, according to the flow of vehicles automatically adjust the traffic light interval
Construction situation
In actual application, the development of Internet of Things requires the participation of all walks of life, and requires the lead of national government and the support of the relevant laws and regulations . Internet of Things carry out is with scale, broad participation, management, technical, And other characteristics, and technical is the most important issues of internet of things;
Internet of things technology is a comprehensive technology, it is a system, at present, no domestic company can be fully responsible for the overall system planning and construction of Internet of things, the theoretical research has been carried out in all walks of life, and the practical application only limited in inner industry. The key of design and R&D of the Internet of Things is RFID, sensor, embedded software and transmission data calculation.
General speaking, Carry out the Internet of Things main including::
1. Identify the object properties, including the static and dynamic, static properties can be stored in the label directly, the dynamic properties first need to be real time detected in sensor.
2. Identification equipment need to read the object properties, and transfer the information to properties data format which suit for network transmission.
Through network transmission the objects information to the information processing center, and the information processing center complete the related calculate of object communication.
Development trend
Industry experts believe that on the one hand the Internet of things can improve economic efficiency, significant saving cost; on the other hand, can provide technical incentives for recovery the global economic. Now the United States, the European Union and so on are made a huge investment to study and explore the Internet of Things. China is also pay highly concerned on internet of things of research, industry and information technology department conjunction with relevant departments are carried out a new generation of information technology, to form a new generation of information technology development of policy measures.
China Mobile President Wang Jianzhou mentioned that the Internet of Things will become the focus of China Mobile's future development. He said he would invite Taiwan produce RFID, sensor and bar code manufacturers to corporation with China Mobile. Using Internet of Things technology, Shanghai Mobile has been tailored data collection, transmission, processing and business management in one set of wireless integrated application solutions for a number of industry customers. The latest data show that more than 100,000 chips have been loaded in the taxi, bus, a variety of internet of things have application of all walks of life, to ensure the city orderly operation. During the Expo, "car traffic" fully applied in the Shanghai public transport system, with the most advanced technology to protect the traffic smooth of the Expo around area. for logistics enterprises transport management "e logistics", will provide the real-time accurate Cargo information, vehicle tracking and positioning, transport path selection, logistics network design and optimization services to users , greatly enhance the comprehensive competitiveness for logistics enterprises.
In addition, after the popularity, for animals, plants and machines, goods of sensors and electronic tags and supporting the number of interface devices will greatly exceed the number of mobile phones. The promotion of internet of things will become another drive to promote economic development and to open up another potential for unlimited development opportunities. In accordance with the current needs of the Internet of Things, in recent years billion sensors and electronic tags will need, which will greatly promote information technology components production , while increasing the number of employment opportunities.
Widely range of uses
The internet of things has wide application. Including the food safety, environmental protection, environmental protection, government work, public safety, safe home, intelligent fire, industrial monitoring, environmental monitoring, elderly care, personal health, flower cultivation, water monitoring, food traceability, enemy investigation and intelligence gathering And other areas.
In 2005, the International Telecommunication Union (ITU) reported draw a picture of the "Internet of Things" era: when the driver failed to operate the car automatically alarm; briefcase will remind the owner what things forget; clothes will "tell" the washing machine the requirements on the color and water temperature and so on. Internet of things logistics applications such as: a logistics company using the Internet of things system trucks, when loading overweight, the car will automatically tell you overload, and how much overload, but there are remaining space, tell you how heavy and heavy goods When the porter unloads, a pack of goods may shout "You throw me hurt" or "Dear, please do not be too brutal, can you?"; When the driver and others in the gossip, truck Will pretend to be the boss's voice roar "fool, the start of the!"
The Internet of Things will use the new generally IT technology in all walks of life bridges, To be specific, the senor will tunnels, highways, buildings, water supply systems, dams, oil and gas pipelines, and so on,. And then the integration of the "Internet of Things" with the existing Internet to achieve the integration of human society and physical systems, in this integrated network, there is the ability to super powerful central computer group, to integrate the network of personnel , Machines, equipment and infrastructure to implement real-time management and control, on this basis, humans can be more sophisticated and dynamic way to manage production and life, to "wisdom" state, improve resource utilization and productivity levels, improve people and The relationship between nature.
