The city lifeline ensures safe operation

On the basis of finding out the bottom number, the application of relevant technologies and digital monitoring system are important supports for digital intelligent management. Chengdu ensures the safety of bridge operation through digital and intelligent management. In Chengdu, the proportion of large overpasses and viaducts is high, and the operation environment of Bridges is complex. Some old Bridges have entered the period of disease occurrence and performance degradation, and Bridges are also faced with the risk of natural disasters such as earthquakes and floods. To this end, Chengdu adopted sensor testing, network communication and data processing technologies to build five sub-systems, such as structural stress, bridge site water level, pier settlement, collision warning and vehicle overload, to obtain real-time bridge operation data and track and evaluate the bridge safety level

The practice shows that the monitoring system plays an important role in bridge security. The digital intelligent management can accurately locate the hidden dangers and causes of bridge safety. For example, the digital monitoring system has recorded the evolution process of the lateral "creep" of the curve beam of the overpass ramp, alerted the abnormal development situation, and timely prompted the beam body to correct the deviation; When the city encounters heavy rainfall, the special monitoring system for bridge water level gives timely warning, and the monitoring personnel have mastered the danger of the bridge girder sealing hole in advance, which has gained precious time for flood prevention and rescue

Risk disposal is a key step to ensure the safe operation of the lifeline of urban infrastructure. According to the relevant person in charge of the Hefei Urban and Rural Construction Bureau, Hefei will push the early warning information to the competent industry departments and transport management enterprises through the monitoring center in the first time, and the leading industry departments will coordinate the risk disposal in the first time, forming a new emergency response mechanism of multi-department linkage, which effectively ensures the safe operation of the urban lifeline infrastructure. The timeliness and standardization of risk monitoring and early warning have been improved.

Create a security industrial cluster

The lifeline safety project of urban infrastructure is not only related to the protection of people's lives and property, but also can drive the development of related industries. In Hefei City, the urban safety industry has become a key industry, which has produced good economic benefits while ensuring the safe operation of the city.

It is understood that Hefei will take the urban safety industry as a key industrial chain, and set up a leading group led by the mayor to promote the development of the urban safety industry to promote industrial development and demonstration and promotion. Hefei City has also formulated a three-year action plan for the development of urban safety industry, established a special industrial fund with a total scale of 1 billion yuan, and built a "fund + industry" urban lifeline promotion model. Establish City Lifeline Industry Group Company, focus on the data cloud platform, monitoring services, ecological cultivation and other core business of city lifeline safety engineering, build an industrial Internet platform for government, enterprises and families, export city lifeline technology, products, programs and services, and accelerate the industrialization of city lifeline.

The establishment of industrial group company is a beneficial exploration in Hefei City to promote the urban lifeline safety project, which is conducive to the sustainable promotion of urban lifeline safety project and provides a reference experience for other cities to promote the infrastructure lifeline safety project. According to reports, the city lifeline Industry Development Group is an Internet platform enterprise in the city lifeline safety industry jointly initiated by Anhui Province, Anxin Technology, Tsinghua University, Jingdong Technology, and iFlytek.

Based on the technologies and products accumulated by Hefei Institute of Public Security of Tsinghua University in the field of urban security, Urban Lifeline Industry Development Group fully integrates 5G, Internet of Things and other new generation information and communication technologies, focusing on the core business of urban lifeline security cloud network integration platform, monitoring and early warning services, industrial ecological investment, etc. To provide a high level of science and technology and industrial supply for the safety of urban lifeline.

According to Yuan Hongyong, executive vice president of the Hefei Institute of Public Safety of Tsinghua University, after about three years of trial and error grinding, the Hefei Institute of Public Safety of Tsinghua University has broken through a series of key technologies, such as gas detection technology, water supply detection technology, heat supply detection technology, and these technologies have good results after application, and then promoted in Anhui province. At present, nearly 60 cities across the country are piloting the application.
