Description

Technical Field

[0001] The invention belongs to the technical field of road slope monitoring, and in particular relates to a large-scale slope intelligent monitoring and early warning system. Background Art

[0002] With the rapid development of public infrastructure, the mileage of highway paving is increasing. When laying highways on some special terrains, in order to avoid the highways being damaged by natural factors such as falling rocks and water flows, it is necessary to set up slopes beside the highways to prevent falling rocks and other factors that affect the use of highways. It can be seen that highway slopes are an important part of transportation infrastructure, and their stability is directly related to traffic safety and the safety of people’s lives and property. With the development of the economy and the acceleration of infrastructure construction, the stability of highway slopes has received increasing attention. Therefore, it is very important to monitor the stability of slopes.

[0003] In the existing slope monitoring and early warning methods, some researchers mainly use the monitoring of slope displacement as an evaluation index for judging slope stability. The commonly used slope monitoring technology is to install displacement meters, inclinometers, rain gauges and other sensors on the slope to monitor the slope in real time. The limitation of this monitoring method is that a set of monitoring equipment can only monitor the status of one point, and the monitoring range is small. If the slope needs to be monitored in all directions, multiple sets of monitoring equipment are required, which greatly increases the economic cost. In addition, some researchers have proposed to set more than one landslide lateral line within the slope range, and set more than one monitoring point on each lateral line to carry out landslide early warning and forecasting. For example, patent number CN113470319A discloses a method for wireless online monitoring and monitoring of landslides. Although the monitoring The method does solve the problem of the operating cost of the former requiring multiple sets of monitoring equipment, but the patent still has some problems. First, the multiple monitoring points set up by the patent require the layout of more lines and connections, which increases the complexity of wiring and increases the difficulty of subsequent maintenance and management; second, the multiple sensors set up by the patent are connected in series on the landslide lateral line, which may increase the risk of paralysis of the entire monitoring lateral line if one of the sensors fails; third, the landslide lateral line and sensor used in the patent are anchored, that is, rigidly connected, and cannot be completely attached to the slope, which may cause some sensors to fail in mid-air, resulting in inaccurate monitoring results; fourth, the method adopts the wiring form of the traditional monitoring method, and multiple line connections will cause electromagnetic interference, which increases the complexity of monitoring and the difficulty of maintenance.

[0004] From the above, it can be seen that the existing slope monitoring methods have many problems such as poor anti-electromagnetic interference and inaccurate sensor monitoring, and are unable to effectively obtain the actual state information of the slope during practical application. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a large-scale intelligent slope monitoring and early warning system to solve the problems of poor anti-electromagnetic interference and inaccurate sensor monitoring in existing slope monitoring methods, and the problem that the actual state information of the slope cannot be effectively obtained during actual application.
