Perception of China’s Internet of Things

Any item in daily life can become "feeling and thinking". "The Internet of Things is very close to us." Ning Jiajun, a member of the National Informatization Expert Advisory Committee, said that in layman's terms, the Internet of Things is to implant various micro-sensor chips on objects to make them intelligent, and then use wireless networks to connect people and people Objects "talk" and objects "communicate" with each other. These objects can be small watches, keys, cars, or buildings. Any object in daily life can become "feeling and thinking." These miniature sensor chips include electronic tags, various sensors, QR codes, etc. They can obtain various contents such as object information, status, and location, and then transmit this information through the network.

The anti-intrusion system of Shanghai Pudong Airport is a typical application of the Internet of Things. In order to prevent uninvited guests from entering, tens of thousands of sensor nodes integrated with many sensors are deployed around Pudong Airport, which can identify targets close to the airport fence and act as an automatic early warning. Liu Haitao, deputy director of the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences, said that this is far better than installing thousands of cameras and sending dedicated personnel to guard them. Internet of Things applications such as Pudong Airport can even distinguish whether a person is climbing a fence or a typhoon. of blowing.

The biggest difference between the Internet of Things and the Internet is that the latter is information interaction between people and is a virtual world. The Internet of Things is the perception and interconnection of the real physical world. Liu Haitao, who is also the director of the Wuxi High-tech Micro-Nano Sensor Network Engineering Technology R&D Center of the Chinese Academy of Sciences, said that the Internet of Things is actually a sensor network. The Internet of Things is from an industry and user perspective, but from a technical perspective, it is called a sensor network. "The most accurate way to describe the Internet of Things and sensor networks is that they are called the Internet of Things and the perception of the world."

In terms of application, the Internet of Things is not unfamiliar. Video surveillance, intelligent transportation, electronic tag (RFID) food traceability management, etc. successfully implemented from the Beijing Olympics are all applications of the Internet of Things. At present, the Internet of Things has been applied in smart buildings, street light monitoring, food and drug traceability, smart hospitals and other fields. Especially in the field of urban public management, there are examples of monitoring and pre-processing of garbage trucks and dangerous goods sources. Many people actually have Internet of Things terminals in their hands. A mobile phone with GPS function is a terminal that can locate.

Mei Shishu, director of the Information Office of Chaoyang District, Beijing, said that in Chaoyang District, in order to prevent deaths caused by carbon monoxide poisoning caused by heating, a pilot program began in March this year, and several rental houses were installed with carbon monoxide. Sensors that can prevent fatalities if discovered within two hours.
