2, The Road Ahead
He predicted the tech trend, all things Internet. Wallet lost items automatically send a message.
3, Kevin Ariston
Connect all objects managed by the intelligent identification and a radio frequency identification sensor and the inter network.
4, the definition of Things
Process information collected by various physical sensing device and real-time technology to form a vast network and the Internet; core things still Internet, on the Internet is the extension and expansion of the network.
Extension and expansion of the user to any article, between the article and the article information is exchanged and communication.
Features: network, intelligent, automatic identification.
5, the evolution of the concept of things
DAQ: data acquisition means, the physical environment is sampled and digitized to provide remote digital solutions. Divided into three parts (the sensor, a signal circuit, the conversion device), because not integrated communication protocols, all without involving communication between devices.
SCADA: collected data by the control and monitoring of the respective facilities, and monitoring of the system operation, and operates the remote terminal. Applied power, oil and other data collection.
M2M: refers to data transmitted from one terminal to another terminal, i.e. the dialogue machine to machine. System configuration M2M applications intelligent machines, hardware M2M communication network, the middleware. M2M application areas, home applications, industrial applications, retail areas and payments, logistics and transport industry, medical industry.
IOT: The various devices and systems connected to the Internet, Internet and communication technologies by Things . With respect to a greater range of M2M should cover all fields.
things is a physical entity set power sensor unit software and the like, by connecting with the outside world, is the mapping of the physical network.
Internet: to ensure that each access of things are unique and can be accessed by other devices in the network in the internet.
Second, the technical characteristics and architecture of Things
Features: Full-aware, multi-data fusion, reliable delivery, intelligent control.
Architecture: perception layer, network layer, application layer.
Public technology and three-tier structure of things have a relationship, including the identification and analysis, security, network management and service quality management.
1, perception layer
By the data acquisition sub-layer, short-range communication technology (WiFi, Bluetooth, etc.), collaborative information processing sub layers.
Get physical event and data information occurs in the physical world through the various types of sensors, various physical quantities involved, logos, audio and other multimedia data. Things the RFID data acquisition by the sensor, two-dimensional code, the implementation of positioning technology - short-range communication technology and the collaborative information processing sub-layer of the data collected in a local co-processing range is reduced to improve the accuracy of information redundancy of information . Perception layer of middleware technology designed to address the compatibility issues between perception and multi-layer data platform, including code, service, status, device management, time synchronization, positioning and so on.
2, the transport layer
Sensing various information data from the transport layer to the application layer through basic bearer network. Including mobile communications network, the Internet, satellite network, network, and industry professionals network.
3, the application layer
Service and application support sub-layer level, the Internet of Things core function is to collect information on the network, the development and utilization. Service support layer functions: accommodate requirements of the business form according to the underlying data collection, real-time updates of the dynamic resource library.
4, key technology of things
Chain networking industry can be divided into: identification, sensing, information transmission, data processing
Core technologies include fusion Mining and radio frequency identification technology, sensing technology, and communication technology and network data.
RFID technology: RFID is a non-contact automatic identification technology, the use of radio frequency signals and the spatial characteristics of the implemented coupling the static, moving, to be automatically identified device identification for acquiring identification information to obtain standardized.
Features: non-contact, weather identification, penetration ability, wear-free connection can automatically identify a plurality of items simultaneously. Application of this technology into the field of the Internet of Things, communication technology, and may be shared item tracking information worldwide. It plays a vital role in the Internet of Things identification information and the level of short-range communications. On the other hand the electronic RFID tag code adopted as the carrier contributed significantly to the development and application of things.
Sensor Technology: information collection is the basis of things, the current information collection is primarily accomplished by sensing the sensor nodes and the electronic tag mode. As a sensor detecting apparatus, the device information extracted by the key occurring environment is very bad and therefore the sensor IOT art proposes higher requirements (ability to feel the information itself and the intelligent network)
Network and communication technology;
Things relates to achieve short-range communication technology (Bluetooth, the RFID) technology and the remote transport (Internet network, the gateway technology). As things provide information service support base channel and transmitting through the communication network to enhance the prior art professional and Internet capabilities to accommodate low mobility things, to achieve secure and reliable transmission of information traffic demand is low the current datalink the study was focused on networking.
Sensor network communication technology include: a wide area network and short-range communication two aspects.
WAN: IP Internet, 2G-5G, mobile communication technology, satellite communications and the like. Ipv6 things for development to provide efficient transfer passage.

Dig Bureau and the Combined Data
Layer perception of things various types of information and the number of application layer are multiplied, doubled relates to data calculations also relates to data between various heterogeneous networks and multi-system integration problem.
How reasonable and effective integration, intelligent mining and processing massive amounts of data is a problem of things, combined with p2p, cloud computing and other distributed computing technology has become the key to solving the above problems. Cloud computing networking provides a new model for efficient computing may provide dynamic low-cost network computing through on-demand, secure cloud data center, the ability to facilitate Internet services, data and applications can easily between different devices sharing, users do not need to worry about information leakage, hacking problem.
