The newspaper went to Guangzhou to correspondent Liu Yang
Ten years ago, no one would have thought that a smart phone would be able to implement almost all functions that can be expected at the same time such as phones, laptops, high-definition cameras, wallets, and game consoles. In the future, if the mobile communication, mobile Internet and other technologies are transplanted to the connection between the Internet of Things and the Internet of Things between people and things, and between things, the subversion effect that may be generated is even more “thinking and fearingâ€: Smart cars, Intelligent light poles, smart bins, smart covers - Whether you like it or not, a pan-intelligence era is blowing. Recently, a reporter of the "Global Times" felt "black technology" that "intelligently creates the future" on the "2017 Tianyi Intelligent Ecological Expo" (hereinafter referred to as "Tianyi Expo") jointly organized by China Telecom and Qualcomm in Guangzhou.
5G makes autopilot closer
The smart age is not achieved by adding sensors to every terminal. Its core technology is the high-speed mobile Internet. According to Yang Jie, Chairman of China Telecom, in the first half of 2017, China Telecom completed the re-cultivation of 800MHz and built a high-quality 4G full-coverage network. The number of 4G base stations reached 1.05 million, and the effective population coverage was 98%. While constantly improving the 4G network, China is continuing to promote ultra-high-speed, low-latency 5G networks. At the Tianyi Expo’s Smart Eco-industry Summit, Wang Zhiqin, deputy director of the China Institute of Information and Communication Technology, stated that with the approach of the 5G standard, China is confident that it will support the domestic commercialization of 5G in 2020.
"Global Times" reporters at the China Telecom booth at the Expo saw that a simulated auto-driving experience machine under 5G conditions was enthusiastically received by visitors. According to field staff, this is the scene of 5G era automatic driving. The uplink and downlink speeds can achieve a large bandwidth of 10G, the delay can be less than 1 millisecond, and the capacity can reach one million levels. With the help of 5G networks, the simulated self-driving car can automatically overtake and avoid roadblocks. Due to the extremely low delay, the car can automatically avoid obstacles 25 meters or more. The car can also receive traffic data in real time and share relevant data with neighboring vehicles at the same time, and it can also send back emergency situations on the road in time.
Can 5G Technology Realize 10G Bandwidth? Staff said that under the conditions of the laboratory, the average user experience speed can reach 1G or more, and a delay of 0.47 milliseconds can be achieved. According to reports, 5G is currently in the stage of laboratory research and field testing. Chinese operators including China Telecom are actively participating in the formulation of 5G technology standards. Although the actual commercial use of 5G will be until 2020, China is currently advancing the evolution of 4G to 5G. Currently, quasi-5G rate experiences can be achieved through multi-carrier, multi-antenna, and high-order modulation technologies.
"I can't think of it, I can't connect to it."
At the high-end forum in this Expo, Yang Jie, Chairman of China Telecom, revealed that China Telecom is leading the global 4G Internet of Things and has built the world's first full-coverage next-generation Internet of Things (IoT) with commercial capabilities based on 4G networks (NB-IoT ), The network is based on 800MHz low-frequency coverage advantages, to achieve full coverage of urban and rural areas, strong penetration.
"Global Times" reporters at Tianyi Wulian and other booths, smart cover, smart fire hydrant, smart trash, children's shoes, smart POS, smart air conditioning, smart door locks, smart lights, smart water meters, smart gas Table, smart agriculture and a series of Internet of Things products. And these products do not stop at the manufacturer's self-satisfaction stage, but have a large number of successful application cases. An Internet of Things company has landed 1,000 fire hydrant monitoring products based on commercial NB technology in Wuhan and landed 2,700 smart manhole covers in Nanchang. The built-in IoT chip's smart manhole cover is very useful. It can both prevent theft and monitor the abnormal opening and closing of the manhole cover in real time. In extreme weather conditions, the municipal administration can effectively prevent the passersby from falling into the pit by monitoring the state of the smart manhole cover.
A smart street lamp that incorporated a large number of functions also attracted the interest of Global Times reporters. According to the staff, the intelligent street light pole can be used as a video surveillance camera, advertising display, electric vehicle charging pile, WiFi signal transmission base station carrier, of course, its main function is to intelligently control the street lamp opening and closing and brightness, the future can also try At the top of the pole, wireless charging for small drones.
Agriculture and animal husbandry are also huge application scenarios for the Internet of Things. The reporter saw a large number of smart Internet of Things products at a booth, such as wireless leaf surface temperature sensors, agricultural environmental monitoring instruments, wireless light intensity sensors and other equipment can be real-time return of the collected data, people can be disposed of in accordance with the data in a timely manner .
Wireless Technology: Conquering the World
Currently, the mobile phone requires a wired charger for charging, a wired cable for charging an electric car, and even a VR helmet with a wired VR or AR video program. Is it possible for us to cut off these "dumps"? Qualcomm gave a new solution. Paul Jacobs, executive chairman of Qualcomm, said that the smart glasses equipped with the Snapdragon 835 mobile VR platform will have powerful endurance capabilities. With computer vision, graphics processing, machine intelligence, and many sensors carried, all of these data will be processed. Fusion, which does not require any cable, and does not require any external device for positioning, can satisfy the user's need to move freely and bring about an immersive experience that is completely autonomous and truly free to move.
Global Times reporters also saw a mobile phone wireless charging device based on magnetic resonance technology at the booth of Qualcomm. The device is very simple, with only one supply coil and one induction coil. As long as the phone is placed within 5 cm of the charging coil, the phone can start charging. According to the staff, the charging time of the wireless charging device may be slightly longer than the wired charging time, but it is completely tolerable compared to the convenience brought by it. For example, during the charging process of a mobile phone, it may take several times to remove and insert the mobile phone charging cable when receiving a phone call or using WeChat. However, the mobile phone in the wireless charging needs only to be picked up and used, and the mobile phone can continue to be charged when it is used up.
The reporter also saw a demonstration of the wireless charging of an electric car at the booth of Qualcomm. The charging coil looks like a sweeping robot fixed on the parking space. The induction coil can be installed on the chassis of the car. When the car goes to the parking space, the two sensors start to charge each other and the general family car can be used. According to reports, due to getting rid of the charging cable, it is theoretically possible to continuously install a magnetic coil for charging on the surface of the road, so that the electric vehicle will continuously charge during the driving process. As to whether this kind of equipment will produce severe electromagnetic radiation, the staff member stated that the charging equipment is equipped with a foreign matter detection device. A child or a kitten or other life station will not start working. If there are foreign objects such as coins, Will work. When charging, as long as the distance from the charging device is greater than 10 cm, the radiation intensity will be greatly reduced, and the test results show that its radiation intensity is lower than that of a mobile phone.
Speech Recognition: Human-Computer Interaction Interface
Imagine that you don't need to find TVs, air conditioners, and other remote controls when you return home. You can complete all instructions by speaking to the speakers. This "black technology" is not out of reach but is already around us.
Global Times reporter experienced a thrill of voice control at the booth of HKUST. The reporter walked into a car equipped with an X-ray speech recognition system. As long as he calls the system's name and then speaks his own needs, it can quickly complete the corresponding instructions. It can not only let it open navigation, but also can send text messages through voice, without touching any key during the whole process, and the recognition accuracy of vocals is very high. After experiencing a variety of products in person, the reporter found that, basically, accurate words can be formed within a few seconds of speaking, and the accuracy of input is above 95%. According to reports, related technologies are currently used in courts and other special situations.
According to the staff, in addition to voice recognition technology, the technology of the University of Science and Technology of China in the field of speech synthesis is also among the world's forefront. The voices of Guo Degang and Lin Zhiling appearing in the navigation software of Gao De and others are by collecting their own high-quality voices for several hours, and then letting the machine simulate their tone, voice, and speech rate. Will such realistic speech synthesis be exploited by criminals? Staff said that letting machines speak like people is still the direction of their efforts. At present, there is no need to worry too much about this aspect. However, with the advancement of technology, this kind of extreme situation in the future is not impossible. Any technological development is a double-edged sword, but it cannot be stopped because it may have certain risks, and it should be from laws, ethics, social norms, etc. Aspects of regulation and management. â–²
