Development of Lift Maintenance Works Portable Camera System with Artificial Intelligence Video Analysis (InspectVision)

I&T Wish Development of Lift Maintenance Works Portable Camera System with Artificial Intelligence Video Analysis (InspectVision)
(REF: W-0584)
Matched I&T Solution
Trial Project
Summary and Challenges
  • The government has required that registered contractors carry out special maintenance on aged lifts at least twice a year since 2018—amounting to roughly 80,000 special maintenance operations annually. With the current resources, only about 5% of these special maintenance tasks (approximately 4,000 inspections) are inspected every year to verify the thoroughness and effectiveness of the work, which is insufficient relative to the total volume of special maintenance operations. Meanwhile, the annual inspection targets have increased considerably—from 14,000 inspections in 2018 to a goal of 30,000 by 2025. This significant escalation highlights an increased recognition of the role that regular inspections play in maintaining safety standards. 
  • However, reaching these ambitious targets requires substantial resources and more efficient management, and the existing system is struggling to meet the rising demand. This makes it difficult to ensure that every aged lift is inspected adequately. In response to these challenges, GLD is considering being given to replacing traditional on-site inspections with a digital, intelligent inspection system. This shift toward a more technologically advanced approach aims to enhance inspection efficiency, ensure better compliance with safety standards, and ultimately improve the overall safety of Hong Kong's aged lifts and escalators.
Expected Outcome
  • The proposed system involves equipping maintenance personnel with body-worn or helmet-mounted cameras. These devices will record special maintenance activities to aged lifts, enabling digital inspections that minimize disruptions to the work. Powered by AI, the system can automatically analyze video footage, detect irregularities or procedural lapses, and alert regulatory personnel for further investigation.
  • This approach not only enhances maintenance compliance to Code of Practice but also fosters better behavioral standards among lift maintenance workers. To demonstrate the effectiveness of this solution, a trial deployment of cameras is proposed. These cameras are designed with an intension to replace traditional on-site physical inspections, showcasing their potential to improve efficiency and regulatory oversight. The trial will evaluate the system’s ability to detect abnormalities, reduce safety risks, and streamline workflows. The benefits of this innovation are far-reaching. Registered Lift Contractor will gain operational efficiency and accountability, while regulatory bodies can monitor more sites with fewer resources. The general public will benefit from safer, well-maintained lifts, fostering trust in the system.
  • Key components of the system include:
    1. Hardware Configuration
    2. Real-Time Data Upload and Integration
    3. Data Security and Privacy Protection
    4. Preparing for AI Video Analysis System
Expected Trial Duration 9-month
