A landslide refers to a certain part of the rock and soil on the slope of the mountain under the action of gravity (including the gravity of the rock and soil and the dynamic and static pressure of the groundwater), which produces shear displacement along a certain weak structural surface (belt) and moves to the bottom of the slope as a whole Functions and phenomena.
There is a lot of rain in the south in summer, so in some mountainous areas, landslides caused by heavy rainfall are easy to occur. Once a landslide occurs near a highway, aisle, or a village, it will not only cause traffic jams, but also cause serious economic losses to the local people.
System composition
The Jixun Wulian landslide monitoring system mainly monitors the various data that will cause landslides in real time through various monitoring stations located near the mountain, effectively monitoring the real-time status of the mountain, and promptly notifying relevant personnel for evacuation if there is an abnormality .
The program consists of three parts, namely:
Front-end monitoring: Real-time monitoring of various important data, such as rainfall, surface displacement, soil moisture content, groundwater, etc., through front-end monitoring stations arranged at various locations on the mountain, and real-time video transmission of the environment through nearby cameras , It can be linked with LED display, speakers and other equipment to provide current notifications before relevant personnel are present.
Data transmission: The data transmission equipment can use TG452 to connect with the front-end equipment through the interface provided by the gateway, and transmit the data through the 5G/4G wireless network, ensuring the stability of data transmission.
Management Center: The management center displays the data transmitted from the gateway on large screens, PCs, mobile terminals and other devices through the smart cloud platform of Jixun, and monitors mountain data in real time. Once the data exceeds the threshold or there is a big data difference compared with before , Will automatically alarm to remind management staff to pay attention. And the management center can remotely send data to the LED display, and perform operations such as shouting through the speaker.
System functions
1. Accurately detect rainfall, surface displacement, soil moisture content, video, deep displacement, GPS, and groundwater data to ensure accurate and real-time data, and the accuracy of location services can reach 1 mm;
2. If the data is too far from the previous one or exceeds the threshold, it will automatically send alarm information to the management personnel through the platform, APP, and SMS, and the management personnel will analyze the actual data again for further processing;
3. Flexible analysis of the change trend of real-time monitoring data/historical data, the trend comparison of similar data in the same time period and the trend comparison of different time periods, can detect abnormalities as soon as possible, carry out preventive work, and ensure safety.
4. The system adopts distributed deployment and is easy to expand. You can add sensors and monitoring stations to maximize the protection of mountain monitoring.
System Features
1. Remote management: The management center can remotely configure the device, upgrade the software and restart the device without visiting the site;
2. Multi-mode transmission: 5G/4G/3G/NB-loT/LoRa/Beidou/wired and other communication transmission methods can be used, and the data can be transmitted to multiple management centers at the same time;
3. Failure display: The location of equipment failure problems can be accurately displayed, the type of failure can be displayed, and maintenance can be performed in time;
4. It can be linked to multiple devices such as wireless early warning broadcast, SMS, platform, LED display screen, etc., to give early warning broadcast, and provide real-time information services for disaster prevention and mitigation.
