Anhui Institute of Building Science Research and Design – Safety Monitoring Project for Old Residential Communities
Project Background
Old residential buildings were mostly constructed in the 1980s and 1990s. Affected by factors such as material aging, foundation settlement, and disturbances from nearby construction, some buildings have developed safety hazards like wall cracks and structural tilting. The Anhui Provincial Institute of Building Science Research and Design is undertaking a research project on safety assessment and reinforcement technologies for old residential areas, which requires long-term, continuous deformation monitoring of typical aging buildings to obtain accurate data on the progression of defects. Traditional manual measurement methods are low-frequency and limited in precision, making it difficult to meet research needs. In January 2025, the institute adopted the housing structural safety monitoring solution from Guilin Spepc Technology, deploying automated monitoring equipment in selected buildings within the old residential communities.
Monitoring equipment
-
Integrated inclinometer : A total of 10 sets, deployed at the building’s load-bearing walls, corners, and critical foundation locations, continuously collect tilt angles along the X, Y, and Z axes as well as vibration acceleration data. The equipment offers an accuracy of ±0.05°, a resolution of 0.001°, supports 4G wireless transmission, and is powered by a built-in lithium‑ion battery, enabling long-term, maintenance‑free operation.
-
Integrated Crack Meter : A total of two sets, installed at existing wall cracks and suspected weak areas, provide real-time monitoring of crack‑width variations (measurement range 0–2000 mm, accuracy 0.02% FS) and simultaneously acquire temperature data to analyze the influence of temperature on crack development.
-
Monitoring platform : All device data is uploaded to via the 4G network SPEPC Building Safety Monitoring Cloud Platform The platform supports real-time data visualization, historical trend plotting, automatic over-limit alarms, and report export, thereby meeting the research institute’s requirements for data traceability and analysis.
Implementation Effectiveness
After the equipment was put into operation, it enabled continuous, automated monitoring of tilt and crack variations in buildings within older residential communities. Researchers at the Anhui Provincial Institute of Building Science Research and Design can remotely access real-time data and historical trends from each monitoring point via the platform, obtaining valuable first-hand deformation data that provides a quantitative basis for safety assessments and the development of reinforcement plans for these older communities. This project represents a successful application of Spepc Technology’s monitoring equipment in the field of building research, demonstrating the product’s stability and data reliability in long-term, continuous monitoring scenarios.
