Problems solved by technology
[0002] In the existing technology, when monitoring slope displacement, monitoring holes are generally made in advance in the monitoring area. In the follow-up process, inclinometers are used to regularly detect the inclination of the monitoring holes, thereby realizing slope displacement monitoring. The labor cost of this monitoring method is Higher, the monitoring efficiency and the comprehensiveness of the monitoring range are poor, and once the monitoring hole is damaged (such as rainfall and water, the soil on the hole wall falls and silts, or the monitoring hole collapses due to soil displacement), it is very necessary to re-drill the hole. trouble

The invention provides a laser ranging-based automatic monitoring system for a deep displacement of a side slope. The system comprises a control module, a communication module and multiple groups of monitoring devices; a plurality of monitoring holes are formed in a side slope monitoring area; the axial direction of each monitoring hole is perpendicular to the horizontal plane; monitoring devicesare arranged in the monitoring holes; multiple groups of the monitoring devices are in one-to-one correspondence with the plurality of the monitoring holes; the single group of the monitoring devicesis composed of a plurality of inclination monitors; and the plurality of the inclination monitors in the single monitoring hole are distributed at equal intervals in the axial direction of the monitoring hole. The laser ranging-based automatic monitoring system for the deep displacement of the side slope has the beneficial technical effects as follows: the system can be arranged in a wide range due to low hardware cost; the system is relatively good in monitoring comprehensiveness, so that after the monitoring holes are destroyed, the monitoring devices can still work; and the system is high in environment adaptability.
Description
technical field [0001] The invention relates to a side slope displacement monitoring technology, in particular to an automatic monitoring system for deep displacement of a side slope based on laser ranging. Background technique [0002] In the existing technology, when monitoring slope displacement, monitoring holes are generally made in advance in the monitoring area.
