Cities, the crystallization of human civilization, are important places where we live. With the acceleration of the pace of new urbanization and new industrialization, the scale of cities in China is getting larger and larger. Characteristics such as a large floating population, dense high-rise buildings, and the agglomeration of economic industries are becoming increasingly obvious. Cities have become a complex social organism and a huge operating system. Emerging risks in urban safety, risks in traditional industries, and regional risks, etc., are accumulating, breeding, complex and changeable, and prone to occur frequently.

The development of science and technology provides strong guarantees for urban safety. Through advanced technologies such as the Internet of Things, big data, and artificial intelligence, we can better monitor, give early warnings, and respond to various urban safety issues.

Urban Safety Operation Monitoring

By constructing a perception and monitoring network that covers the full scenarios in the fields of urban lifeline projects, production safety, natural disasters, and public safety, functions such as real-time perception, online monitoring, prediction and early warning, and emergency response of urban safety operations are realized. A comprehensive urban safety operation risk monitoring and early warning platform with comprehensive coverage, complete functions, and sound operations is formed to further enhance the urban safety risk prevention and control ability and the proactive protection ability of urban safety.

Comprehensive Urban Safety Risk Monitoring and Early Warning Platform

Bridges

Regarding the safety of urban bridges, in accordance with relevant regulations such as the "Technical Specification for Monitoring of Building and Bridge Structures" (GB50982) and the "Technical Regulations for Safety Monitoring Systems of Highway Bridge Structures" (JT/T1037), priority is given to monitoring the risks of bridges with poor safety conditions and high operation risks, as well as bridges with important or complex structures. Combining with the actual situation, at positions such as the bridge deck, piers, and bottom slabs, monitoring equipment such as displacement, deflection, acceleration, dynamic strain, static strain, inclination angle, and crack width are used to monitor relevant parameters such as the deformation of the bridge structure, the structural stress, and the dynamic response. Monitoring equipment such as video, temperature and humidity, and wind speed and direction are used to monitor the external loads and meteorological environment that affect the safety of the bridge.

Water Supply and Drainage Pipelines
For urban water supply networks and their affiliated facilities, in accordance with the relevant regulations of the "Technical Regulations for the Operation, Maintenance and Safety of Urban Water Supply Networks" (CJJ207), priority is given to conducting risk monitoring at the hydraulic dividing lines of the pipeline network, the water intake points of large users, and the intersections of large pipeline sections. Combining with the actual situation, the main indicators monitored are the flow rate, pressure, and leakage sound waves of the pipeline network.
For urban drainage networks and their affiliated facilities, in accordance with relevant regulations such as the "Technical Regulations for the Detection and Assessment of Urban Drainage Pipelines" (CJJ181), priority is given to conducting risk monitoring at parts such as flood control and drainage facilities and sewage interception and source control facilities. The main parameters monitored are important parameters such as drainage and flood control, source control and sewage interception, and spatial explosion.

Urban Waterlogging

Regarding urban waterlogging, it is required to fully understand the rainfall situation in the city, the real-time drainage and water storage capacities of the city, and meteorological data, basic geographical data, etc. should be comprehensively considered. Mainly, the accumulated water level and video monitoring of low-lying and waterlogging-prone areas are carried out; the rainfall monitoring of key protection areas is carried out; the water level monitoring of important rivers is carried out, and the flow rate and water level of the river water bodies are measured in a non-contact way.

Reservoir Dams
Regarding the safety of reservoir dams, in accordance with the provisions of the "Technical Specification for Safety Monitoring of Earth and Rock Dams" (SL551-2012), at positions such as the dam slopes, dam crests, dam toes, and dam shoulders of the reservoir, monitoring equipment such as displacement, settlement, cracks, seepage pressure, flow rate and direction, water level, precipitation, and video are used. The temperature, humidity, rainfall, water level, seepage flow, seepage pressure, surface deformation, internal deformation, and soil pressure of the reservoir and the dam body are monitored to evaluate the safe operation status of the dam.

Engineering Construction

Regarding the safety of engineering construction operations, mainly the settlement of the surrounding surface, the settlement and inclination of the buildings (structures) along the line, the horizontal/vertical displacement of the foundation pit support structure and the support axial force, the displacement of the deep soil, the pore water pressure, and the groundwater level are monitored; the parameters such as the crown settlement and the clearance convergence of the formed tunnel are monitored; the operation status parameters of the shield machine are monitored. Regarding the risks such as the leakage of gas pipelines and water supply and drainage pipelines caused by construction operations such as piling, jacking, excavation, and drilling around underground pipelines, as well as the risk of subway tunnel breakthrough, within the protection scope of key areas such as underground pipelines and their affiliated facilities and subway tunnels, feature recognition technologies such as images and elastic waves are used to perform model matching on construction machinery and equipment such as excavators, piling machines, and hook machines that enter the protection area, and to monitor and identify in real time whether there is third-party construction within the protection scope.
