1. The Internet of Things (IOT for short) refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted with through a variety of information sensors, radio-frequency identification technology, global positioning systems, infrared sensors, laser scanners, and other various devices and technologies to collect its acoustic, optical, thermal, electrical, mechanical, chemical, biological, location, and other The information is collected in real time from any object or process that needs to be monitored, connected, and interacted with.
2. Composition: The basic features of IOT can be summarized as overall perception, reliable transmission and intelligent processing.
(1) Overall perception - radio frequency identification, two-dimensional code, intelligent sensors and other sensing equipment can be used to perceive the acquisition of various types of information about the object.
(2) Reliable Transmission-Through the integration of the Internet and wireless network, the information of the object can be transmitted in real time and accurately, so as to exchange and share information.
(3) Intelligent Processing-Use various intelligent technologies to analyze and process the sensed and transmitted data and information to realize the intelligence of monitoring and control.
Expanded Information:
Commonly used cases are:
1, IoT sensor products have been the first to be applied in the anti-intrusion system of Shanghai Pudong International Airport. The airport anti-intrusion system laid more than 30,000 sensing nodes, covering the ground, fences and low altitude detection, which can prevent people from overstepping, smuggling, terrorist attacks and other offensive invasions. And just a short time ago, the Shanghai World Expo also signed an order with the Wuxi Sensor Network Center to buy anti-intrusion micro-nano sensor network 15 million yuan of products.
2, ZigBee street light control system lighting Jinan Park Expo. ZigBee wireless street lighting lighting energy saving and environmental protection technology is a major highlight of the Park Expo Park. All the functional lighting in the park adopts ZigBee wireless technology to reach the wireless street light control.
3, Intelligent Transportation System (ITS) is the use of modern information technology as the core, the use of advanced communications, computers, automatic control, sensor technology, to achieve real-time control of traffic and command management. Traffic information collection is regarded as the key subsystem of ITS, which is the basis for the development of ITS and becomes the prerequisite for transportation intelligence. Whether it is traffic control or traffic violation management system, are involved in the collection of traffic dynamic information, traffic dynamic information collection has become the first task of traffic intelligence.
