Description

Technical Field

[0001] This invention relates to the field of geological disaster monitoring and early warning technology, specifically to a foreign object intrusion monitoring and early warning system and method. Background Technology

[0002] Due to atmospheric precipitation, foreign object intrusion into perimeter areas, such as landslides on highways and railways, can pose safety hazards to personnel or vehicles within the perimeter. Because foreign object intrusions have a degree of randomness, they are difficult to predict or detect through prior observation and analysis or patrols. Therefore, monitoring foreign object intrusions at perimeters is a relatively effective means of preventing loss of life and property. The railway line slope landslide early warning device (publication number CN114383509A) uses a laser rangefinder sensor to measure the actual value L3, which is less than the set value. The normally open contact of the L2 sensor outputs a relay action, and the cloud alarm power supply is powered on through the normally open contact of the sensor to automatically issue an early warning. When the application scenario of the equipment is to monitor the risk of landslides on railway slopes, it becomes a railway slope landslide early warning device. It can realize real-time monitoring and early warning of whether there is a risk of landslides on specific sections of railway slopes, but it cannot respond to the specific section or scale of the landslide. In addition, if people or animals block the view, it will cause false alarms that cannot be resolved in time. In order to solve the problem of monitoring and early warning of foreign objects intruding into the perimeter, a method for monitoring and early warning of foreign objects intruding into the perimeter of slope landslides is proposed.

The monitoring crossbar 16 is connected to the force transmission rod 17 by the bolt 18 and the connecting screw 24. The distance between two adjacent monitoring columns 14 is 5-7m. The outer surface of the force transmission rod 17 is coated with lubricating oil. Monitoring by pressure sensor 15 and force transmission module, when a landslide object 30 intrudes into the designated perimeter of the slope, the slope includes the slope excavation line 25, slope platform 26, slope surface 27, and natural slope line 28. The landslide object 29 compresses the monitoring crossbar 16, and the compressive force is transmitted through the object intrusion monitoring crossbar 16 to the monitoring columns 14 at both ends, and then transmitted through the force transmission rod 17 to be sensed by pressure sensor 15. The distance between two adjacent monitoring columns 14 is 5-7m, preferably 6m.

[0026] The power supply and energy storage system includes a support column 3, a pole 6, a solar panel 7, and a charging cable 8.

[0027] A method for early warning and monitoring of foreign object intrusion in a perimeter monitoring and early warning system includes the following steps:

[0028] (1) The rain gauge is monitored online in real time by the monitoring instrument control unit;

[0029] (2) When monitoring detects that the rainfall measured by the rain gauge reaches a certain level, the rainfall h j At that time, the monitoring instrument control unit begins to power all pressure sensors and monitor pressure data; h j A predetermined rainfall value;

A pole 6 is erected, and monitoring columns 14, monitoring crossbars 16, and other components are installed at equal intervals. When the rainfall monitored by the rain gauge 10 exceeds the set value, the monitoring instrument control unit of the data acquisition and transmission system 4 starts supplying power to the pressure sensor 15 and begins data acquisition. When a landslide occurs and foreign object 30 intrudes into the set perimeter, the landslide object 30 compresses the monitoring crossbar 16. The compressive force is transmitted through the monitoring crossbar 16 to the monitoring columns 14 at both ends, and then transmitted through the force transmission rod 17 to the pressure sensor 15. The pressure data sensed by the pressure sensor 15 is transmitted to the data acquisition and transmission system 4, which then issues an early warning. The pressure sensor 15 monitors data exceeding f... j At that time, the monitoring instrument control unit starts to power the camera and record the area, and issues a landslide intrusion warning. The video information serves as the information for manual verification of the warning, and reacts to the specific section and scale of the landslide. If it is a false alarm due to animals or human compression, the alarm is extinguished.
