Bedrock mark stability monitoring system

The invention discloses a bedrock mark stability monitoring system which comprises a sensing system, an acquisition, analysis and transmission system, a power supply system, a bedrock mark, a fixing system, a display system and a light reflecting system. The device can replace a static force level gauge monitoring system to be used for monitoring bedrock mark stability and ground subsidence, adopts the laser displacement sensor for distance measurement, has the advantages of small size, high sensitivity, small influence by temperature difference and large measuring range compared with a liquid surface type static force level gauge, has the advantages of high precision, low system complexity and the like compared with a pressure difference type static force level gauge, and is suitable for popularization and application. The system has a remote communication function and can display the bedrock mark state and the land subsidence condition in real time. 本发明公开了一种基岩标稳定性监测系统，包括感知系统、采集分析传输系统、供电系统、基岩标、固定系统、展示系统和反光系统
