Recently, at the '2025 Municipal Engineering Construction Industry Expo,' Hikvision presented its all-encompassing solution for the safety monitoring and early warning of urban lifelines. Concentrating on five pivotal scenarios—waterlogging drainage, gas supply, water supply, roads and bridges, and utility tunnels—the company demonstrated its state-of-the-art technologies and real-world accomplishments in intelligent sensing and the proactive prevention and control of urban infrastructure. This effort is facilitating a transition in urban governance from a 'reactive emergency response' mode to a new era of 'proactive early warning.' During the expo, notable visitors to Hikvision's booth included Lai Ming, a member of the National Committee of the Chinese People's Political Consultative Conference and former Deputy Secretary-General of its 13th National Committee; Wang Kaifeng, Deputy Director-General of the Urban Construction Department at the Ministry of Housing and Urban-Rural Development; Han Song, Deputy Director-General of the Urban Management Supervision Bureau at the same ministry; Lu Yingfang, President of the Municipal Engineering Association; Jia Mingyan, Director of the Urban and Municipal Management Professional Committee of the Municipal Engineering Association, among other distinguished guests.

Cheng Jiaji, the General Manager of Hikvision's Municipal Business Department, delivered a keynote address at the concurrent Urban Municipal Facility Lifeline Safety Engineering Seminar. He emphasized Hikvision's dedication to urban lifeline safety, highlighting its 'Intelligent IoT' strategy and the application of Hikvision Guanlan large model technology. By amalgamating multi-dimensional sensing technologies, including laser, optical fiber, millimeter-wave radar, sound waves, temperature, and pressure, the company has crafted a comprehensive solution for scenarios like gas, water supply, drainage, bridges, and utility tunnels. The intelligent IoT monitoring system has been implemented in over 80 cities and districts, facilitating precise risk identification, swift early warning, and efficient collaboration. This contributes to bolstering urban safety resilience and modernizing governance capabilities.

Waterlogging Drainage: Precise Early Warning through IoT Sensing and AI Recognition

In response to the recurring issue of urban waterlogging, Hikvision displayed its radar water level observation gun-ball integrated system on-site. This system employs high-precision radar to monitor water level fluctuations in real-time, coupled with video verification and AI analysis for second-level identification and graded early warning of water accumulation risks. It offers visual aid for emergency dispatch and drainage decision-making, significantly enhancing urban flood control and drainage response efficiency. The exhibition also showcased a broad spectrum of monitoring and early warning capabilities, encompassing rain gauges, buried liquid level monitors, and sensors for pipeline liquid levels, flow velocity, flow rate, and water quality, along with an intelligent monitoring platform. These tools enable pipeline defect diagnosis, waterlogging diffusion simulation, pipeline blockage analysis, and infiltration flow analysis.

Gas Safety: Dual Early Warning Mechanism for 'Behavior and Leakage,' Fortifying Underground Defenses

To tackle high-risk hazards like gas leaks and third-party construction damage, Hikvision introduced an innovative 'station-network-end' integrated solution. In station and pipeline network settings, the system achieves second-level monitoring of combustible gas concentrations using TDLAS technology, accompanied by second-level alarms and real-time video verification. Utilizing the Hikvision Guanlan large model, it also detects dangerous behaviors such as third-party construction damage, smoking, and phone use by station personnel, establishing a dual-dimensional early warning mechanism for 'leakage perception and behavior recognition.' At the gas usage end, technologies based on laser and semiconductors enable combustible gas leak monitoring and automatic shutoff for residential and commercial users, effectively transitioning gas safety management from post-incident response to proactive prevention and safeguarding urban gas safety.

Water Supply Network: Multi-Dimensional Sensing Integration for Precise Leak Source Detection and Loss Reduction

To address challenges such as the difficulty in detecting leaks in the water supply network and high localization costs, Hikvision exhibited a range of products, including electromagnetic flowmeters, pressure gauges, and pipeline leak monitors, to create an integrated system for zone metering and leak monitoring. The system can detect abnormal pipeline pressure and flow in real-time, swiftly locate leaks, effectively reduce leakage rates, and assist management departments in achieving refined operation and maintenance and efficient resource utilization.

Road and Bridge Monitoring: Millimeter-Level Precision Ensuring Bridge Structural Safety

Hikvision unveiled its visual displacement monitoring cameras, crack monitoring cameras, and displacement observation balls, which employ sub-pixel image analysis algorithms to capture minute changes in bridge deflection and cracks with high frequency and without distortion. Combined with AI ISP image enhancement and specific wavelength illumination technologies, the system effectively mitigates interference from high temperatures, heatwaves, and fog, maintaining high-precision monitoring capabilities in complex environments and providing reliable protection for road and bridge structural safety.

Utility Tunnels: Robots, Optical Fiber Sensing, and Intelligent Firefighting for a Fully Automated Inspection System

To elevate the automation level of tunnel monitoring, Hikvision showcased a suite of products, including tunnel inspection robots, fiber Bragg gratings, temperature-sensing optical fibers, vibration-sensing optical fibers, and intelligent firefighting systems. Fiber optic sensing technology enables millimeter-level precise monitoring of tunnel structural deformation and environmental temperature changes. Tunnel inspection robots conduct automated patrols, utilizing high-definition video and intelligent analysis to monitor facility conditions inside the tunnels in real-time. Intelligent firefighting integrates traditional firefighting with visual AI, thermal imaging, and multi-band flame detection technologies, significantly enhancing the intelligence and refinement of tunnel management through a 'static-dynamic combined' stereoscopic monitoring mode. This reduces manual inspection costs and ensures the safe and stable operation of urban 'underground arteries.'

Furthermore, Hikvision collaborated with ecological partners to display innovative equipment such as pipeline CCTV inspection robots in the partnership exhibition area, further bolstering urban underground pipeline network inspection and assessment capabilities and fostering an open and collaborative urban lifeline safety ecosystem.

As a frontrunner in intelligent IoT sensing for smart cities, Hikvision will persist in its focus on urban lifeline safety. Leveraging AI, IoT, and multi-dimensional sensing technologies as its core, the company aims to propel municipal infrastructure towards greater intelligence, resilience, and safety, laying a robust digital and intelligent foundation for high-quality urban development.
