This system is mainly composed of MC-DC-6 integrated crack monitoring station and MC-DA-2 integrated wireless sound & light alarm device. The crack monitoring station is responsible for real-time data collection of crack change and acceleration. Sound & light early warning alarm device is responsible for displaying the early warning information in both form of sound and light on scene. The sound and light can present different forms of patterns of manifestation according to different warning level. The two can be linked through remote cloud platform or on-scene Lora to realize monitoring and early warning.
                           

MC-DC-6 crack monitoring station adopts an integrated design, which integrates telemetry terminal, communication module （Full Netcom /Lora）, power supply system, rope displacement sensor and monitor & protection pole. This design eliminates the complicated work of establishment of pole and cabinet. By optimizing the design, the monitoring station has a overall simple and coordinated appearance. And due to its high integration, its small size saves packaging, transportation and installation costs.

MC-DC-6 integrated crack monitor station   MC-DA-2 integrated sound & light alarm
MC-DA-2 wireless sound & light alarm has integrated design to integrate three-color control module, voice synthesis module, communication module（Full Net/Lora）, power system and monitor protection pole. In the case of early warning, three colors of light reminders are presented according to different warning levels and three synthesized voice reminders can also be triggered. It can realize single-point linkage and multi-point linkage with the crack monitor station.
