The Internet of Things is a dynamic global network infrastructure with self-organizing capabilities based on standards and interoperable communication protocols, in which physical and virtual "things" have identity, physical attributes, and intelligent interfaces, and seamlessly integrate with information networks. IoT will form the Internet of the future along with the Internet of Media, the Internet of Services and the Internet of Enterprises. Simply put, IoT is a network that connects the physical world by integrating sensors and sensor networks, RFID and other sensing technologies, communication networks and Internet technologies, and intelligent computing technologies to realize comprehensive sensing, reliable transmission and intelligent processing. On this basis, human beings can manage production and life in a more refined and dynamic way, to achieve the "wisdom" state, the wisdom of the Earth, the wisdom of life.
The main application areas of IoT are smart city, smart transportation, smart home, smart security, wearable products, agriculture, logistics, medical and so on.
(A) Smart City
The impact of the Internet of Things on city management is mainly reflected in the unified monitoring of urban security and digital management of the city. Unified monitoring of urban safety based on broadband Internet real-time remote monitoring, transmission, storage, management of business, decentralized, independent image collection points for networking, the realization of the unified monitoring of urban safety, unified storage and unified management for urban management and builders to provide a new, intuitive, visual and auditory range of the extension of the management tool.
(B) Intelligent Transportation
The most important thing is to drive on the road is safety, through the collection of digital video surveillance, vehicle GPS, intelligent traffic lights, cell phone signaling and other traffic information, you can get real-time information on the road conditions and positioning of the vehicle, so that each vehicle **** to enjoy the data, so as to optimize the trip for the vehicle to alleviate traffic congestion, choose the parking location. Traffic management authorities can use IoT technology to intelligently dispatch and manage public **** traffic such as cabs and buses, intelligently induce private vehicles to control traffic flow, scout, analyze and record violations of traffic rules and regulations, and seamlessly detect, mark and automatically collect tolls for vehicles entering and exiting highways, ultimately improving traffic capacity. In the future, vehicles will be connected to the network through IoT technology, making urban transportation more flexible. As a result, intelligent transportation will reduce congestion, lower fuel consumption and CO2 emissions, improve people's travel, and enhance their quality of life.
(C) smart home
The narrow sense of the smart home is a variety of consumer electronic products, communication products, information appliances and smart home through the Internet of Things for communication and data exchange, to realize the family network of various types of electronic products between the "interconnection", so as to achieve anytime, anywhere, on the smart device control. control of smart devices anytime, anywhere. For example, the refrigerator can detect objects full and record, and then remind; home environment system detects indoor humidity is too high, it will cooperate with the start of the air conditioning to take dehumidification measures; kitchen fume concentration is too high, it will start the range hood; weather suddenly rain or too much noise outside, it will automatically close the windows; solar radiation is large, it will automatically close the curtains. The Internet of Things in the home appliance industry can also be combined with e-commerce, when your coffee machine found that the coffee beans are almost finished, you will be reminded to take coffee beans out of the cabinet to replenish, but if the cloud host to compare your consumption record in e-commerce, found that you have not recently purchased the coffee beans, it will be transmitted to the cell phone to remind the replenishment of the information.
Broadly speaking, smart home refers to the construction of intelligent community, mainly to the information network, monitoring network and telephone, television network as the center of the community network system, through efficient, convenient and safe network system to achieve a high degree of information integration and **** enjoyment, to achieve the environment and mechanical and electrical equipment automation, intelligent monitoring. Intelligent community can be through the community integrated network for HVAC, water supply and drainage monitoring, public *** area lighting, parking lot management, background music and emergency broadcasting and other property management, as well as access control systems, video surveillance, intrusion alarms, automatic fire alarms and fire linkage and other community security prevention.
(D) Intelligent Security
In the field of intelligent security, home security is an important part of social security, modern families are increasingly concerned about home security, security products are no longer "high on the" high-end technology, Internet of Things technology will give it a more "personal, low-key". Pro-people, low-profile" image, constantly stationed in the ordinary people's families. For example, we are more familiar with home smart cameras, window sensors, smoke monitors, etc., through intelligent monitoring can be viewed in real time on the phone home situation. At the same time, a variety of intelligent alarm equipment access, greatly enhancing the performance of home security.
(E) smart wearable products
Internet of Things to realize the connection of things, the need for network access points, and wearable devices than the smartphone, wearable devices are easier to carry, more suitable for the Internet of Things medium and carrier. By opening up the core link of IoT, wearable devices not only allow smart devices to interconnect, but also realize human-machine interaction. The wearer does not need to spend too much energy to deal with various trivialities in life through wearable devices, making life more convenient. For example, smart bracelets can remotely control smart devices at home such as smart refrigerators and smart air conditioners. If you find that there is not enough food in the refrigerator and the air conditioner has forgotten to turn off, the smart bracelet can remind the user in real time and will even handle these things automatically.
(F) Intelligent agriculture
Through real-time collection of temperature and humidity signals in the greenhouse, as well as light, soil temperature, CO?concentration, leaf surface humidity, dew point temperature and other environmental parameters, automatically turn on or off the specified equipment. It can be processed at any time according to the user's demand, providing scientific basis for automatic monitoring of comprehensive ecological information of facility agriculture, automatic control of environment and intelligent management. Through the module to collect temperature sensors and other signals, through the wireless signal transceiver module to transmit data, to realize the greenhouse temperature and humidity remote control.
(VII) Intelligent Logistics
For the user, intelligent logistics can provide a search engine to query the status of goods in a timely manner, and ensure that the quality and quantity of goods on the basis of rapid delivery to the hands of users. For goods producers and transportation enterprises, intelligent logistics can optimize the logistics chain of raw material procurement, semi-finished product transportation and deployment and finished product delivery to the user terminal, helping enterprises to determine the location of raw materials, optimize the procurement location, formulate inventory allocation strategy, and realize a seamless supply chain from the supply side to the user side. This improves enterprise control, while also reducing inventory pressure, lowering capital and time costs, improving customer service, and enhancing enterprise competitiveness.
(viii) Smart healthcare systems
The healthcare industry will also be completely disrupted by the IoT. People are already using wearables like the Fitbit to track and improve their personal health, and some devices like Bluetooth-enabled insulin pumps can already transmit data about diabetics' blood sugar levels directly to their doctors. Possible future developments include under-the-skin sensors that can detect a patient's vital signs, home monitoring systems that can sound an alarm if first aid is needed, and even improved appointment systems that work off of real-time schedule data from doctors. As the U.S. population ages, these solutions are helping to equalize the growing demand on an already clunky healthcare system. With the help of simple and practical home healthcare sensing devices, smart healthcare systems can self-measure the physiological indicators of a sick or elderly person in the home and transmit the generated physiological indicator data over the network to the caregiver or the relevant healthcare unit.
The Internet of Things will eventually permeate almost every aspect of our lives.
