The Internet of Things technology is considered by many scientists and engineers to subvert the world. What kind of technology is it, what development trend will it have, and what field will it be used?
1. What is the Internet of Things
The Internet of Things, as the name suggests, is the "Internet of Things Connected". The definition of the Internet of Things is to use infrared sensors, radio frequency identification (RFID), global positioning systems, laser scanners and other information sensing equipment to connect any item to the Internet according to an agreed protocol for information exchange and communication. A network for intelligent identification, tracking, positioning, monitoring and management of items.
For example, home doors and car doors can automatically identify the owner, open when the owner comes, and close when the owner leaves; various household appliances can be automatically controlled according to our preferences; when you are away, the use of IoT-based intelligent transportation will make our driving more in Apple pie order.
2. The development field of the Internet of Things
At present, the global IoT industry market is growing rapidly. The current global IoT applications mainly include four major areas:
1. Energy industry 2. Transportation application 3. Home security 4. Medical and health
(Key areas of IoT applications)
Among them, the European and American markets are mature, mainly focusing on applications such as automotive information and communication services, automatic meter reading, etc.; the Asia-Pacific region mainly focuses on enterprise informatization applications, environmental monitoring and smart homes, represented by China, Japan and South Korea; the United States Internet of Things Typical applications include smart grids (optimized management of power generation, transmission, distribution, and power consumption systems), smart logistics (large retail enterprises), and smart dust (military fields, health monitoring, environmental monitoring). China now also attaches great importance to the technological development of the Internet of Things, and now there is also the major of the Internet of Things in teaching.
Third, the Internet of Things technology has entered our lives
1. Smart home
Before leaving get off work, the host uses his smart phone to give orders to the household appliances in the house, and prepares in advance to welcome the host home. Press the button to start the water heater, and take a shower when the owner goes home; the rice cooker starts cooking, and the owner can eat ready-made meals when they get home; the refrigerator can also actively display the amount of food stored and the place of origin ; The air conditioner can be turned on in advance to slowly adjust the temperature to a suitable range for the human body.
(1) Home automation
The US Electric Imp company earlier released the latest Imp, which is a cloud-based automation solution that monitors and manages everything you own. You can install a small Imp card, connect to your home WiFi, and control devices through Imp's cloud service. Each home device can immediately recognize other devices and "talk" with each other, and you can be anywhere in the world Use a browser or smartphone to control your home devices. The interaction will be divided into three levels: Imp and Imp, Imp and people, Imp and service. In this way, no matter where you are, as long as you control your own device and select the command, the appliances in your home will automatically start to work. For example, come to a bath before get off work: fill me with hot water, sprinkle with fragrance, and I will have an imperial bath when I get home.
(2) Home sensor
Small sensing devices can be used on switches, doors, windows, air conditioners, and fitness equipment. Through these sensors, the owner of the home can easily monitor the conditions of the home, such as the door, temperature, TV and other equipment. In this way, anywhere in the home, you can freely manipulate and do whatever you want. If this technology can be implemented and promoted, owning a fully electronically controlled mansion like Bill Gates is no longer a dream.
(3) Smart refrigerator
Companies such as Samsung and LG have begun to produce smart refrigerators. Samsung recently exhibited a refrigerator using Android App at CES. LG recently launched a refrigerator that can provide food management system services. This means that your refrigerator can also do things like online shopping. At the same time, it can also recommend you what to buy, what to do, and what to eat based on what is in the refrigerator. At the same time, we may have much more than that. Game giant EA is also boldly cooperating. Wilson, the head of EA Sports, said, “When you open the refrigerator to get milk, a push message of ULTIMATE TEAM (a mode of strategic management in FIFA) may pop up on the screen, and then you click accept. You can enter the game." In other words, play the game while holding the fruit? Wait...what did I just want to take?
(4) Touch screen home appliances
If Corning works well, touch-screen displays will eventually be embedded in, for example, closet doors, dining tables, and other surfaces. These screens have their own operating system and can exchange information with each other. This, at present, the most complete configuration must be the home of the younger brother Lin Zhiying. If you are interested, you can visit his home for yourself.
(5) Smart lighting
The iPhone is not as simple as a mobile phone, and the traditional switch should be retired. The United States has recently developed Wi-Fi lights. With these lights, you can use your iPhone to design your home lighting system, and you can turn on or off all the lights at the same time. In addition, you can install LIFX smart bulbs. It can be controlled by wifi, is energy-saving, and has a multi-color display, which can be controlled by Android or iOS phones. During the New Year, you must be beaming, come with a little red, and if you want to be romantic, add a little Mediterranean blue. In short, Lifx can bring you a light control experience that you have never had before.
2. Smart medical
(1) Wireless medical
Your medicine box notices that you should refill your prescription, and calls to make an appointment for you; a sensor implanted under your skin detects fluid accumulation in your lungs, and then reminds your doctor; your doctor decides accordingly Your heart disease prescription needs to be adjusted, and then contact the pharmacist to change your dose. At the same time, sensors in your toilet confirm that your body has adapted well to other drugs, but there are signs that you may be on the verge of developing diabetes. Physical examination is not something that happens only once a year. It happens every day, just as you carry out your daily life.
(2) Appointment registration and queuing system
As long as we have opened the bank card appointment registration service, we can make an appointment without waiting so long. This breaks the previous time and space limitations for patient registration and telephone appointment. Bank card appointment registration can be made through service terminals and online banking, which can save a lot of waiting time.
(3) Telemedicine
The "telemedicine" ambulance under development is equipped with operating tables, anesthesia machines and monitors. It can realize real-time connection and data exchange with the hospital command center and collaborative units through 3G and Internet of Things technology. When the patient is on the road, the hospital will already know all the symptoms of the patient, and can arrange treatment for the patient in a very good and timely manner, so that the hospital will not be caught off guard.
3. Intelligent transportation
The application of Internet of Things technology to taxis can solve the problem of "difficult taxis". By giving each taxi a unique number, it connects cars to cars, cars to people, and cars to the public network to realize information sharing. Use sensors to collect information on vehicles, roads, and passengers, and process, calculate, share, and publish the information on the control center. In this way, the real-time information of the vehicle, including longitude, latitude, speed, status and other information can be displayed on the electronic map, so that the vehicle can be effectively guided and supervised.
When passengers need to take a taxi, they only need to open the mobile phone map to see the operation of nearby taxis. The control center will know the current accurate location of the passengers through the mobile phone's global positioning system, and provide the passenger status of the taxis nearby. And location information. Passengers only need to touch the location of an empty taxi on the map to send a booking signal to the taxi. After waiting for the driver's confirmation, the two will establish a connection through the network, and can conduct real-time voice calls, and display the distance between the two and the time when the taxi arrives at the passenger's location. At the same time, passengers can also make reservations in advance, as long as they enter the specific time and click on the specific location on the map to make a taxi reservation. When the passenger arrives at the scheduled place according to the scheduled time, they will find that the scheduled taxi is already waiting.
Users can also search for "same travelers" through their mobile phones, find people who start at the same time and have similar distances, and join them in carpooling. It is also more convenient in terms of payment. Passengers can use the mobile payment function of their mobile phones to pay for the fare. When passengers accidentally forget their finances in the car, they can easily inquire about the information of the vehicle they are in, ensuring the financial safety of the passengers.
The Internet of Things is also applied in other more fields, such as "smart city", "Internet of Vehicles", "environmental monitoring" and many other technologies are developing rapidly. When everything is interconnected, everything can communicate and communicate with data to realize a smart earth. ,The wisdom of life.
