Wuhan Zhongdi Hengda - Crack Monitoring System
System Introduction
The integrated crack monitoring system is mainly used for real-time automated monitoring of the width of tensile cracks that have already appeared in landslides and structures. It is applicable to fields such as national land geological disaster monitoring, mine geological disaster monitoring, water conservancy and hydropower monitoring, dam monitoring, and dangerous building monitoring. The monitoring system adopts an integrated design, integrating sensors required for crack monitoring, data acquisition, data transmission, solar power supply, pole brackets, and other components into one, making field installation operations simple and convenient.
