Internet of Things: coming to work, not swiping at the door, only brushing the face

In the future, people go to work is not "swipe card" but "brush their faces" into the door; even if no one is at home, the smart home system can also virtually "scene" scare away the thief... Today, the reporter learned from the Zhangjiang Hi-Tech Park. According to the IoT Ventilation Conference, Zhang Jiang has opened an incubator of nearly 5,000 square meters in the first phase of the power port, a group of leading companies in the Internet of Things in China and even in the world, and has developed various high and new technologies to form an agglomeration effect and protect people's daily lives. Safety.

Fire-fighting optical fiber sensors have no fear of high temperatures Due to the high number of high-rise buildings in the city, fire safety of high-rise buildings has become one of the most concerned issues of urban safety. “There is no absolute security in the world. What we can do is to identify hidden dangers early and make corrections at the first time, killing the hidden dangers in the “cockroach.” The only company in Shanghai that integrates R&D and manufacture of optoelectronic devices and equipment is one According to the person in charge of Communications Technology Co., Ltd., the company has developed "distributed fiber optic sensors" and "fiber grating sensors." The former can detect the temperature data of numerous inductive elements on the fiber at the same time; while the latter can detect the exact temperature change at a certain point on a fixed point.

Compared with ordinary smoke detectors and temperature detectors, what are the advantages of fiber optic fire detection systems? “Traditional smoke and temperature sensors have internal components such as circuit boards and diodes, which can easily be burned out when exposed to open flames. However, the optical fiber itself has extremely high temperature resistance properties. , Can withstand high temperatures of 500°C-600°C, especially in the concealed laying state of the optical fiber sensor, can work effectively on the premise of the building does not collapse, help firefighters understand the situation of the fire, and quickly rescue trapped people.

Personnel security access control system “brush face” recognition In September of this year, a jail broke out in a domestic prison. The fugitives used a small metal plate made of self-made transformer cores to make trapezoidal tools to open the prison area door. “We have developed a corresponding access control system that uses biometric identification technology, which is commonly known as “face brushing” technology to supervise access control. If it is not a “human face” certified by the system, it cannot be opened.” According to Zeng Wenbin, vice president of Shanghai Yinchen Intelligent Identification Technology Co., Ltd., the only 863 industrialization base in the field of biometric identification identified by the Ministry of Science and Technology of China, this system has been applied to prisons, bank vaults and other important sites, and will gradually be applied later. Civil market promotion. Now, the door of the company uses this kind of access control system and scans the photos of the company's employees into the system beforehand. When they go to work, everyone can “sweep” and they can come in. No more cards are needed.

Home security using mobile phones to monitor their homes "Many people understand the smart home from Bill Gates's home life, but the real application of this technology is not a lot." Shanghai Feng Mao Information Technology Co., Ltd. is a use of the United States core technology, Providing intelligent home systems and intelligent integration solutions provider, General Manager Dai Yizhen introduced that the smart home platform can effectively prevent gas leakage and other incidents from happening. Once it detects a gas leak, it will not only report to the police at the first time. It can also open the window automatically, or open the exhaust fan to dilute the gas, reducing the risk.

The more magical function of smart systems to protect home security is theft prevention. "After using the smart home system, it will be done without war and defeat." Dai Yijun said, "The thief will usually knock on the door before entering the house to see if there are any people in the house. If no one responds, they will do something wrong. The smart home system will create a “virtual scene” when it detects a stranger knocking at the door. For example, if you hear the knock on the door, the system will directly turn on the TV, or turn on the faucet, or even play music. This sound makes The thieves mistakenly believe that someone is indoors and fled.”

With the smart home system, users only need to log on a dedicated website with their computer or mobile phone, and they can monitor everything in their home at any time, including opening and closing lamps, closing doors and windows, and automatically shutting off power.
