It is used for landslide early warning, mine safety, and bridge and tunnel monitoring, providing crucial data for disaster early warning and engineering safety.
Crack monitoring system is a technology device specifically designed for the continuous and automatic monitoring of the development and changes of cracks on the surface of the earth or artificial structures. This system uses high-precision sensors to capture minute changes in crack width, length, or relative displacement in real time. Its monitoring data is a key basis for assessing structural stability and providing early warnings of geological disasters.
The core function of the system is to accurately measure the geometric changes of cracks. It mainly monitors the expansion or contraction of crack width, the extension of crack length, and the vertical or horizontal relative displacement occurring on both sides of the crack. Monitoring accuracy is typically down to the millimeter or even sub-millimeter level, effectively identifying early, slow deformation trends. This function makes it an important tool for predictive maintenance and disaster prevention.
In terms of application areas, Crack monitoring system mainly serves four major scenarios. In the field of geological disaster early warning, such as in landslide and collapse-prone areas, the system continuously monitors the activity status of surface cracks through sensors deployed on them, providing front-end data for the establishment of early warning models and emergency response. In mine safety management, the system is used to monitor cracking in slopes, spoil heaps, tunnel roofs, and support structures to prevent roof falls, spalling, and slope instability accidents. In civil engineering, critical cracks on the surfaces of structures such as bridges, tunnels, dams, and high-rise buildings are key monitoring areas; long-term data can be used to assess the structural health and service performance. Furthermore, the system plays an important role in environmental monitoring projects, such as the stability monitoring of tailings dams and landfill slopes.
Achieving automatic, efficient, and accurate monitoring depends on the system's technical composition. A typical system consists of three parts: a field monitoring unit, a data transmission unit, and a data management platform. The field monitoring unit consists of sensors directly installed at the cracks; common types include crack gauges, displacement sensors, or vision-based image monitoring stations. These sensors can adapt to complex outdoor environments, maintaining measurement stability under conditions of temperature changes, humidity fluctuations, and general pollution. The data transmission unit is responsible for remotely transmitting analog or digital signals collected by sensors to the monitoring center via wired (e.g., cable, fiber optic) or wireless (e.g., LoRa, 4G) methods. The data management platform is the system's central hub, responsible for receiving, storing, displaying, and analyzing all monitoring data.
The platform software features real-time data viewing, historical curve plotting, statistical analysis, and report generation. Users can clearly observe the change curve of each crack over time. The system typically sets multiple warning thresholds. When the crack's rate of change or cumulative change exceeds preset safety limits, the system automatically triggers multi-level alarms, notifying relevant personnel via software interface, SMS, or email to facilitate timely on-site investigation and decision-making.
Therefore, Crack monitoring system, through its high-precision, automated, and real-time continuous technical characteristics, transforms crack monitoring from traditional manual periodic inspections and measurements to a digital, networked, and intelligent continuous monitoring model. It significantly improves the ability to perceive and respond to risks related to cracks—a critical safety indicator—in complex engineering and geological environments, making it an important technological tool for ensuring life and property safety and achieving intelligent safety management.
