The team took the lead in undertaking the first "open competition" (enlisted-and-commanded) project in the transportation field of the National Key R&D Program, "Key Technologies for Precise Identification and Intelligent Diagnosis and Treatment of Hidden Defects in Railway Infrastructure". The team also took the lead in undertaking the Shenzhen Peacock Team Program project "Key Technologies and Complete Equipment Sets for Smart Sensing of Urban Underground Space Structures", committed to improving the intelligence level of infrastructure maintenance. Supported by these projects, the team developed complete sets of technology and equipment for intelligent tunnel structure diagnostic vehicles, including lightweight diagnostic vehicles, towed container comprehensive diagnostic vehicles, and self-propelled comprehensive diagnostic vehicles. It also developed a series of multi-dimensional smart sensing equipment for metro tunnels, multi-modal intelligent sensing technology for tunnel service state, multi-system coupled collaborative configuration, a cloud platform for tunnel service state sensing, and a central control system based on precise spatiotemporal synchronization and multi-element collaboration. These can accurately identify various tunnel diseases while processing inspection information and data online, realizing real-time diagnostic warning of hidden tunnel diseases, and achieving independent research and development across the whole process from new equipment to new technology, new systems, and new platforms. It greatly improved the automation and intelligence level of tunnel disease diagnosis. The research results won the First Prize of the Hebei Provincial Science and Technology Progress Award in 2024.

The team took the lead in undertaking the CZ key special research task of the National Key R&D Program, "Complete Technology for Intelligent Detection of Equipment Status and Rapid Construction Risk Monitoring in Drill-and-Blast Tunnels". Relying on the CZ Railway, the team focused on extremely harsh engineering environments such as high-altitude hypoxia, high ground temperature hazards, high ground stress rockbursts, large deformation of soft rock, and fractured fault zones. Addressing major engineering technical needs such as intelligent and precise detection of tunnel diseases and risk prevention and control of rapid construction, the team independently developed a complete set of technologies and equipment for safety monitoring of tunnel construction personnel, equipment, surrounding rock structures, and environment. These include precise positioning technology for personnel and equipment in tunnels, multi-band and multi-standard wireless communication technology, smart safety helmets with positioning + vital signs + environmental monitoring, and long-distance distributed optical fiber sensing technology. An integrated safety monitoring platform for the drill-and-blast tunnel construction process was built, providing key technical support for the construction of drill-and-blast tunnels on the Sichuan-Tibet Railway. The research task passed its performance evaluation in January 2025, with a rating of "Excellent".
