The business competition of the Internet of Things technology has been launched around the world; wireless networks and optical cable networks complement each other, and the watt network, mobile phone network, and broadcasting network are converging the three networks, CDMA, WIFI, RFID Blooming everywhere; perception of China and smart earth have also been activated.
On the one hand, we must have an impressive user experience with Microsoft’s new collaborative somatosensory product; people can play video games remotely using voice, gestures, and body movements. Voice and motion replace traditional remote control. Device. On the other hand, we also have an impressive user experience for iPad and iPhone capacitive touch sensing and horizontal and vertical position sensing. The focus here is on the application of sensor technology in these terminals.
(1) Application of sensor technology.
The above-mentioned functions of sensor technology have extremely important applications in the military, national defense, and medical and health fields.
In the field of industrial and agricultural production, the factory’s automatic assembly line, fully automatic processing equipment, and many intelligent testing instruments and equipment all use a large number of various sensors, which are in a rational production, It has played a huge role in reducing people's labor intensity and avoiding harmful operations.
In the field of household appliances, fully automatic washing machines, rice cookers and microwave ovens are all inseparable from sensors.
In the medical and health field, electronic pulse meters, clinical thermometers, medical ventilators, ultrasonic diagnostic equipment, tomography (CT) and nuclear magnetic resonance diagnostic equipment, all use a large number of various sensing technologies . These have played an important role in improving people's living standards, improving their quality of life and health.
In the field of military and national defense, various detection equipment, infrared night vision detection, radar tracking, and precise guidance of weapons are difficult to achieve without sensors. In the aerospace field, sensors are required for air control, navigation, aircraft flight management and autopilot, and instrument landing blind landing systems.
The remote sensing and remote measurement of artificial satellites are closely related to sensors. If there is no sensor, it is impossible to realize such a function. In addition, sensors have a wide range of applications in the fields of mineral resources, marine development, life sciences, and bioengineering. Sensor technology has been highly valued by various countries and has developed into a specialized technical discipline.
(2) The position of sensors in information technology.
Sensor technology is an eye-catching high-tech technology that has developed rapidly in the world today, and it is also an important symbol of the development of contemporary science and technology. It, together with communication technology and computer technology, constitutes the three pillars of the information industry.
In the new technological revolution and the development of the information society, sensors are the pioneers and important technological foundations of modern technology.
When the integrated circuit and computer technology developed rapidly, people gradually realized that the information ingestion device-sensor-did not keep up with the development of information technology, and exclaimed "the brain is developed and the facial features are not working". Sensors began to receive widespread attention. Since the 1980s, a wave of "sensor fever" has gradually risen worldwide.
The U.S. Department of Defense regards sensor technology as one of the key technologies. Japan ranks sensor technology alongside computers, communications, laser semiconductors, superconductivity, and artificial intelligence as the six core technologies. Germany regards military sensors as Priority is given to the development of technology. The development and investment of sensors in Britain, France and other countries has been upgraded year by year, and sensor technology is listed in the Russian military aerospace program.
The United States established the National Technology Group (BTG) as early as the early 1980s to help the government organize and lead the development of sensor technology for major companies and national enterprises and departments, and claimed that the world has entered the sensor Times.
Among the 22 technologies that are vital to the long-term security and economic prosperity of the United States, 6 are directly related to sensor information processing technology. Among the key technologies that are vital to protecting the quality advantage of the US weapon system, 8 of them are related to sensors. In 2000, the US Air Force listed 15 key technologies that will help improve the capabilities of the Air Force in the 21st century, and sensor technologies are among them.
The Japanese businessmen claim that "the new era can be dominated by controlling sensor technology." Japan attaches great importance to the development and utilization of sensor technology and ranks it as one of the six core technologies of the country's key development. Among the key scientific research projects in the 1990s formulated by the Japan Science and Technology Agency, there are 70 key topics, of which 18 are closely related to sensor technology.
It is precisely because countries around the world pay attention to and invest in development, the development of sensors is very rapid, and the annual growth rate of its output and market demand has been above 10% in the past ten years. At present, the number of units engaged in sensor development and production in the world has increased to more than 5,000. The United States, Europe, and Russia each have more than 1,000 manufacturers engaged in sensor research and production, and Japan has more than 800.
(3) The ubiquitous Internet of Things.
Walking on the road and looking around, there are surveillance cameras everywhere, and the Internet of Things has become a common tool to protect the people. Approaching the property community, infrared probes, microwave alarms, and Internet of Things security have become necessary equipment for property management. When you walk into residential houses, the Internet of Things is ubiquitous, such as wireless Internet access, Internet of Things video phones, and automated gas detection.
Going to work, fingerprint access control and attendance has become the steward of IoT enterprise management. Traveling, swiping cards has become a trend: buses, swiping cards; parking lots, swiping cards; highways, swiping cards; staying in hotels, swiping second-generation ID cards.
The Internet of Things enables human beings to "heart-to-heart", walking in crowded commercial districts, the Internet of Things will always perceive the opportunity of gathering in six dimensions; as long as there are friends nearby, the Internet of Things will automatically use mobile phones to date. So everyone got together and talked.
Internet of things technology makes new energy sources at your fingertips. The Internet of Things has become indispensable for mankind.
Google Earth has made the Internet of Things technology to its extreme. It cleverly combines satellite sensor technology, cloud computing technology and Internet browser technology, and combines satellite images, maps, encyclopedias and flight simulations. With integrated devices, anyone can swim through the mountains, oceans, virgin forests, etc. through the 3D virtual earth.
