In a residential community built in the 1990s in northern China, 120 aging elevators are undergoing an "intelligent transformation." These elevators, averaging over 25 years of service, frequently encounter issues such as floor malfunctions, abnormal door operations, and excessive noise. For residents, each "trap" incident signifies a loss of trust.

The Equity Proposition of Public Space

As mentioned in the previous article, elevators in public spaces are crucial for social equity, and in old residential communities, they serve as "vertical passageways" connecting generations and quality of life. However, among the approximately 220,000 aging communities nationwide, over 60% of elevators remain disconnected from digital monitoring systems, relying on manual experience for maintenance, with potential hazards often overlooked.

From "passive emergency repairs" to "active protection"

The renovation project employs an AI monitoring module that collects real-time data on braking, vibration, temperature, and other parameters via sensors, then uploads it to a cloud-based system for health assessment. Upon detecting abnormal parameters, the backend can push alerts to maintenance personnel within 30 seconds, enabling "predictive maintenance" and reducing elevator downtime by over 40%.

Breaking the "black box" of maintenance and repair, rebuilding residents' trust

The system also opens access to property owners, allowing residents to check maintenance records and operational status at any time, breaking the opaque "black-box maintenance" model. Data shows that the complaint rate in pilot neighborhoods dropped by 78%, while in property satisfaction surveys, "sense of security" emerged as the highest-scoring category.

Beyond technology, there is the return of trust

The intelligent transformation of old elevators is not merely a technological upgrade, but also a reconstruction of trust.

When data is transparent, responses are swift, and information is shared, residents regain trust in "elevators as reliable partners," and the warmth of the city quietly returns.
