Typhoon FIREWORKS Hit, Urging The Construction Of Smart City To Accelerate

In this case, the government is hindered in disaster control, and LED display plays an important role in the rescue work because of its timeliness of early warning information release and guidance of command and dispatching. The occurrence of this disaster also urges the construction of smart city without delay. In this way, in accelerating the pace of smart city construction, LED display will obtain great market opportunities in the field of smart city with its good performance.

LED screen plays an important role in smart city construction

In mid July, typhoon "fireworks" attacked most cities and towns in Henan Province from the Pacific, causing great economic losses and life safety threats. The waterlogging is urgent, the early warning of urban waterlogging is not timely, the information is asymmetric, and there is a lack of unified evacuation emergency management, which leads to the delayed transmission of road condition information and rescue information, and the affected people cannot obtain the guidance of the best escape route, making it even more difficult for the trapped people to escape. This major waterlogging disaster has sounded an alarm to urban management, and it is urgent to accelerate the construction of smart city. In the future urban governance, whether in major natural disasters, environmental governance, traffic coordination and other aspects, it is calling for the emergence of more intelligent service terminal carriers. As the "big brother" who has entered the terminal display market for many years, LED display also takes this responsibility. With the continuous development and innovation of technology, the subdivided application fields of LED display are also expanding, and its advantages are more prominent: first, led weather display has a weather warning system, with infinite network as the carrier, providing the transmission of text information under the meteorological emergency state of sudden disasters. Taking the Zhejiang weather forecast project as an example, the LED screen displays the maximum and minimum temperatures of today and tomorrow, with early warning lights to help people manage their travel in their daily life. In addition, the LED weather display does not need on-site wiring. In the case of flood and rainstorm, it can also avoid the display failure caused by electric leakage or line short circuit. 

Second, provide auxiliary information release means at large-scale disaster relief sites to transmit data, images and other information. In some disaster areas that cannot be reached by rescue workers, the disaster situation cannot be judged specifically. Through the early warning system of LED meteorological display screen, the disaster situation can be estimated through functions such as photography and big data cloud computing, and the on-site data can be reflected with functional departments, so as to provide efficient and powerful support for emergency command and remote auxiliary decision-making. Moreover, the LED weather display has the advantages of fast construction, low-cost and intuitive information release system, which is not limited by the site and has strong applicability. Third, when the disaster has not occurred, the disaster early warning shall be issued in time to realize the display of multiple information cycles and minimize the disaster losses as much as possible.

Frequent disasters urge us to speed up the construction of a smart city

China has a vast territory, large east-west and North-South geographical span, complex and diverse climate types and terrain. Therefore, meteorological disasters in varying degrees often occur in many areas during seasonal precipitation, especially urban waterlogging. It is urgent to speed up the pace of new urban infrastructure to alleviate waterlogging. In the process of smart city construction, the most mentioned is smart display.

Smart display covers all aspects of the whole city. It needs to be equipped with a powerful intelligent data information processing system. The smart city data management system with the large screen as the display core can realize the comprehensive integration and sharing of urban operation information, establish a centralized real-time cooperation environment, and provide a highly efficient, safe and reliable command and dispatching platform for the city in terms of organization, management, coordination, command, dispatching and operation. Comprehensively display the multidimensional macro situation of the city, such as "economic innovation, public security, living environment, people's well-being and government construction", analyze the current situation in various fields, generate problems, put forward suggestions and automatically form a written report according to the perceived data. At the level of emergency management, the monitoring video within the city can be called to sense the situation of emergency events at the front end, and the "situation data model" can be automatically generated through big data analysis, so that the command and dispatching personnel can quickly and conveniently understand the situation of the whole jurisdiction and make timely and correct response to emergencies.

The intelligent management system of "digitization, modularization and centralized management" with small spacing LED display screen as the core realizes a series of requirements such as "system integration, real-time data display, networked data transmission and intelligent maintenance and management", which will effectively promote the construction of intelligent city. It also plays an indispensable role in building a big data visualization platform for smart cities.

Is smart display impeccable? Security issues should not be ignored

Although the prospect of smart city is promising, it is always an emerging thing. On the road of exploration, we have not accumulated rich experience in safe operation and management. With the advent of 5g era, the era of Internet of things is coming, which means that it is more necessary to strengthen the security protection of information content for intelligent display terminals. In the information transmission chain, the terminal operators who need to consolidate the information security barriers most are to prevent the terminal display carrier from being attacked by technology, resulting in information leakage and economic losses.

Different from the traditional Internet, the Internet of things(IOT) needs to connect a large number of interfaces, data, devices and applications. It is oriented to the real world and can directly affect the real world. Therefore, the intelligent display carrier that has experienced the problem of content security will face more severe challenges after linking the IOT. Ideally, content display security can be improved at the beginning of the development of the IOT. However, the reality is that the corresponding content display security system can be established only after the framework of the LED industry chain of the Internet of things is established. Compared with the Internet of things, content security lags behind, increasing the control risk of bad information. Therefore, smart display terminals should pay more attention to content security and strive to promote the improvement of content security awareness in the industry.
