The advent of the 5G era has brought various possibilities to life. In order to further understand the application and construction of smart buildings in the 5G era, in the morning of October 10, the Tianhe Central Business District Management Committee organized building representatives to visit and study in Guangzhou Unicom 5G + Innovation Center. At the scene, Unicom staff showed various "black technologies" in building management in the 5G era to the building representatives, and the participants at the scene frequently praised and marveled.
5G not only needs fast network speeds, but also emphasizes the application of scenarios such as the Internet of Things.
The 5G + Innovation Center in Baodi Plaza is the only 5G showroom in the province. According to reports, in the 1980s, the network used analog signal transmission, and the 1G network was formerly a wireless communication network. After the first generation of mobile communication system was born, people also realized their dream of walking and talking on the phone. At that time, having a big brother was a status symbol.
In the 1990s, the cellular communication infrastructure was gradually improved, the network adopted digital modulation, and more data transmission services were added, and mobile phones could send text messages and other functions.
In the 3G era, communication has brought about a period of high-speed IP data networks. The advent of large-screen mobile phones has diversified communications, high-bandwidth and stable transmission, and the transmission of video phones and large amounts of data is more common. The 3G era is regarded as The key to a new era of mobile communications.
The 4G all-IP data network has also ushered in the video era. With the support of new technologies, it can transmit high-quality video images.
The 5G era ushered in today is called the era of the Internet of Everything. Fast network speed is one of the characteristics of 5G. Not only that, 5G no longer blindly pursues the experience rate of human-to-human communication (10-100 times that of 4G), but more emphasis is placed on meeting the Internet of Things, high-definition video, cloud computing, Multi-scenario industry applications such as AI, VR, connected cars, and drones.
New technologies such as smart access control, security, and parking lots have landed
It is understood that 5G combines artificial intelligence, mobile edge computing, end-to-end network slicing and other technologies, and has broad application prospects in VR / AR, ultra-high-definition video, vehicle network drones, intelligent manufacturing, and smart cities.
According to the data of Guangdong Tower Company, as of September 9, Guangdong Province has completed more than 11,858 5G base stations, leading the country. Among them, Guangzhou has the most, with more than 6,945 5G base stations already built. Nandu reporter recently learned from the three major operators that there are currently more than 30 5G applications in Guangdong province, involving the most scenes in the country. The 11 districts of Guangzhou City have already deployed their respective 5G plans.
During the visit, the staff showed the guests the current application of 5G in different fields, the use of smart police, and simulated the scene of tracking fugitives with 5G networks. In the field of smart retail, 5G technology can be used at home. See the high-definition live broadcast to VR Wandian interconnected intelligent central control system.
Among them, the application of 5G empowerment in the field of smart buildings attracts the attention of visitors.
According to the plan, Guangzhou will subdivide 5G functions in 11 districts of the city, each with its own positioning and theme. Among them, Tianhe is positioned as 5G + Smart CBD. This is closely related to the construction of smart buildings.
5G application cases of 15 buildings and communities are displayed on the touch screen computer, including smart Access control systems , intelligent security, intelligent parking lots and other new technologies, there are many scenes that have already been implemented.
Once a traditional office building arrives at the peak of work, there will be a long queue waiting for the elevator. This reporter saw in the 5G smart elevator control Zhongnandu. This practice realized the intelligent linkage control of the elevator and the access control system, and successfully identified the identity of the resident and the tenant After that, the elevator will automatically wait for the first floor, and send the residents or visitors to the designated floor. It is convenient to take the elevator while reducing the waiting time, and at the same time to stop the behavior of people who do not have the right to take the elevator.
In community applications, smart manhole covers have attracted the attention of many visitors. In daily life, many people have heard of the missing manhole covers. The intelligent manhole cover part can add real-time tracking to the manhole cover by adding sensors on the back side of the manhole cover. In the event of loss, it will communicate with the background to communicate information. When the water level is too high, it will also send an alarm reminder. The staff introduced that the price of a sensor installed on the back side of the manhole cover is more than 20 yuan, and this technology has been used in some areas.
Can a building be demolished and replaced with a 5G signal? Not necessarily
It is understood that there are currently buildings in Guangzhou that have certain intentions for 5G applications. 5G networks are arranged in buildings. For traditional office buildings, many managers will worry that the network layout must be achieved through "big demolition and construction."
The field staff introduced that the established impression in the past is that wired transmission is more stable. In the 5G era, it is not particularly limited to this situation. Wireless transmission has strong stability. This technology will reduce many wiring transformations. The device transmits signals, reducing the cost of retrofitting. It is not necessarily achieved through the "big demolition and big construction" method, but also needs to be determined according to the project and budget situation.
Some building representatives were curious about the cost control brought about by the application of 5G technology. Staff shared on the spot and found that according to the existing case tracking data that has been put into trial, the energy consumption was the most effective. The data for half a year showed that energy consumption was reduced. 12%, personnel, such as patrol robots to replace manual patrols, night patrols to transmit data back to the background, reducing 1/3 security patrols.
People flow analysis, not only to identify bad people, to make appropriate business decisions through flow analysis and judgment, has a certain guiding role. It is understood that there are currently owners in the CBD Super Business Supermarket trying.
According to the staff, the application of smart buildings is not only a reflection of technological innovation, but also economic development and the pursuit of smart living. Through the building of smart buildings, it helps companies to achieve energy saving and emission reduction, reduce costs, increase efficiency, and improve personal convenience Degree, improving the overall environment, etc.
In addition, smart buildings also play a role in building management for data collection and accumulation. The staff introduced, "The traditional building industry has a very high degree of work experience, which ignores the value and summary of the value of data. In the data age, data understands buildings better than anyone else, and is the basis for digital building management."
The image of the staff is large, and the data of the sensor equipment is massive, diverse, and complicated. Through the scientific management of these data, integration and reuse, it is like human blood, which is used to transport nutrients while de-roughing and extracting fines, cross-correlation and early warning defense.
