Description

Technical Field

[0001] The invention belongs to the field of geological disaster early warning, and specifically relates to an anchor-fixed collapse and rockfall monitoring and early warning method based on vibration induction. Background Art

[0002] The most direct hazard of rockfall disasters is the threat to people's lives. When rockfall occurs, both pedestrians and passengers in vehicles may be directly hit by the rocks, causing serious physical injuries or even death. This sudden event often catches people off guard, increasing the risk of casualties. Large rockfalls may directly block roads, causing traffic interruptions and affecting the normal passage of vehicles and pedestrians. Even if the rocks do not completely block the roads, they may cause the roads to narrow and the traffic capacity to decrease, increasing the risk of traffic congestion. Rockfalls hitting vehicles may not only cause vehicle damage, but also cause traffic accidents, further exacerbating traffic chaos. Rockfall disasters may also cause damage to infrastructure such as roads, bridges, culverts, and tunnels. The damage to these facilities not only affects transportation, but may also trigger chain reactions, such as bridge collapse, landslides and other more serious disasters. In addition, rockfalls may also damage power, communication and other lines, affecting the normal lives of local residents. Summary of the invention

[0004] In order to realize the above-mentioned technical features, the purpose of the present invention is realized as follows: an anchor-fixed collapse and rockfall monitoring and early warning system based on vibration sensing, comprising a vibration sensor module for sensing rockfall vibration; different numbers of vibration sensor modules are set according to the size of the terrain in the area and a dot matrix network is formed; the vibration sensor module is connected to a power supply module for providing electrical energy; the vibration sensor module is connected to an intermediate data processing platform via wireless or wired communication, the intermediate data processing platform is used to receive data fused by the dot matrix network, and analyze the data to generate different types of early warning information, the intermediate data processing platform is connected to an early warning module for issuing different types of early warning signals via wireless or wireless communication; the early warning module is connected to an early warning processing module, and the early warning processing module sends out the early warning information according to different early warning methods.

[0005] The vibration sensor module includes a plurality of anchor-type fixed vibration sensors, which are fixed on the hillside and can be replaced when damaged.

[0006] For the same monitoring area, n dot matrix networks formed by anchor-type fixed vibration sensors are set up, and the dot matrix networks in different areas can also be integrated to fully cover the monitored area.

[0007] The power supply module uses solar panels.

[0008] The dot matrix network formed by the anchor-type fixed vibration sensors transmits data to the intermediate data processing platform via Bluetooth transmission.

[0009] The intermediate data processing platform classifies the warning information and sends the classified warning information to the warning module according to different levels of warning information. The warning module will send the warning information through different channels according to different levels of warning information.

[0010] The early warning module has set up three different early warning channels, namely sound and light warning, information warning and contact with emergency departments. The sound and light warning is set up for the scene of rockfall; the information warning is mainly sent through network means; and the contact with emergency departments is that the intermediate platform automatically contacts the relevant emergency departments to deal with the rockfall disaster.

If the vibration situation is not serious, only a simple sound and light warning will be carried out on site, or corresponding warning lights, light signs or horn voice prompts will be set up. If the vibration signal is strong, it is necessary to cooperate with the information prompts and contact the relevant emergency departments.

[0013] An anchor-fixed collapse rockfall monitoring and early warning method based on vibration sensing: In step 1, the vibration sensor module deploys sensors at key locations in potential rockfall areas, including: mountain tops, steep slopes, and rock cracks; In step 3, the intermediate data processing platform processes the data by classifying the vibration signal, classifying the signal according to the amplitude and frequency characteristic parameters of the extracted vibration signal, and setting different thresholds to distinguish between signals of different levels such as normal vibration, slight vibration, and severe vibration; dynamically adjusts the classification standard according to the change of the real-time vibration signal and the operating status of the mechanical system, and feeds back the classification result to the relevant personnel or system so that maintenance or repair measures can be taken in time; In step 4, there are various ways to notify the rockfall perception warning information, thereby ensuring that the warning information can be quickly and effectively conveyed to relevant personnel when the risk of rockfall is monitored so that timely response measures can be taken.

The present invention uses the above-mentioned early warning system, and the notification methods of rockfall perception early warning information are various, and each method has its unique advantages and applicable scenarios. In practical applications, a variety of notification methods can be comprehensively selected according to factors such as the specific situation of the monitoring area, personnel distribution and early warning needs to ensure the timely and accurate communication of early warning information.

[0021] Furthermore, the vibration sensor module 1 includes a plurality of anchor-type fixed vibration sensors, which are fixed on the hillside and can be replaced when damaged.

[0023] Furthermore, the power supply module 2 uses a solar panel. The solar panel equipped separately for powering the sensor eliminates the disadvantages of traditional cable power supply, reduces environmental pollution, and has a long service life and low maintenance cost, thereby reducing later operating expenses.

[0024] Furthermore, the dot matrix network formed by the anchor-type fixed vibration sensors transmits data to the intermediate data processing platform 3 via Bluetooth transmission, thereby facilitating the wireless transmission of data.

[0025] Furthermore, the intermediate data processing platform 3 classifies the warning information and sends the classified warning information to the warning module 4 according to different levels of warning information.

If the vibration signal is strong, it is necessary to cooperate with the information prompts and contact the relevant emergency departments.

[0029] An anchor-fixed collapse rockfall monitoring and early warning method based on vibration sensing: In step 1, the vibration sensor module 1 deploys sensors at key locations in potential rockfall areas, including: mountain tops, steep slopes, and rock cracks; In the step 3, the intermediate data processing platform 3 processes the data by classifying the vibration signal, classifying the signal according to the amplitude and frequency characteristic parameters of the extracted vibration signal, and setting different thresholds to distinguish between signals of different levels such as normal vibration, slight vibration, and severe vibration; dynamically adjusts the classification standard according to the change of the real-time vibration signal and the operating state of the mechanical system, and feeds back the classification result to the relevant personnel or system so that maintenance or repair measures can be taken in time; In step 4, there are various ways to notify the rockfall perception warning information, thereby ensuring that the warning information can be quickly and effectively conveyed to relevant personnel when the risk of rockfall is monitored so that timely response measures can be taken.

[0030] Embodiment 3: 1. Different types of sensors are set up according to different terrain and geology to monitor rockfall, which requires comprehensive consideration of terrain characteristics, geological conditions, monitoring requirements and sensor performance characteristics; the steep mountainous area has large undulations, rocks are easy to loosen, and the risk of rockfall is high, so it is necessary to monitor the loosening, displacement and rockfall of rocks in real time; the gentle hilly mountainous area has a relatively gentle terrain, but there may be local rock loosening or soil erosion problems. Image processing technology can be combined to conduct large-scale video monitoring to identify small rockfalls or signs of soil erosion; the river valley area has a strong scouring effect of water flow, and the river bank is easy to erode, which may cause landslides or rockfalls. The stability of the river bank is monitored to warn of landslides and rockfalls. Soil moisture sensors or displacement sensors can be used to monitor the displacement of river bank rocks or soil.

[0031] 2. Sensor layout strategy and point layout principles: According to the terrain and geological conditions, the location and density of monitoring points should be reasonably determined. The monitoring points should be as close as possible to potential rockfall sources or dangerous areas. For key monitoring areas, sensors should be deployed more densely.

[0032] 3. Key points for the implementation of detection technology, data calibration and verification: Calibrate and verify sensors regularly to ensure the accuracy and reliability of monitoring data. Warning threshold setting: Reasonably set warning thresholds based on historical data and risk assessment results of the monitoring area. Emergency response mechanism: Establish an emergency response mechanism to immediately initiate warning and response measures once rockfall risks are detected.

[0033] 4. Use the early warning module to select the appropriate channel for early warning based on the intensity and signal classification of the detected vibration signal, and minimize unnecessary information prompts.

[0034] Embodiment 4: The present invention installs vibration sensors according to specific circumstances and takes different terrain and geology into consideration. The number and type of sensors installed in different environments can be specifically considered, avoiding the disadvantage of using only a single sensor. Among the sensors of the same type, a more economical and reliable one can be selected. The perception of vibration mainly depends on the vibration sensor. Therefore, the selection of the sensor is particularly important in combination with the specific circumstances. It is necessary to comprehensively consider the terrain characteristics, geological conditions, monitoring requirements and the performance characteristics of the sensor.

[0035] The dot matrix integration of vibration sensors can be deployed in a grid to improve the accuracy and comprehensiveness of monitoring. The monitoring area can be divided into several small areas, and a certain number of sensors can be installed in each small area. This can form a dense sensor network to achieve full coverage of the monitoring area. Wireless communication can be carried out through Bluetooth. Since the monitoring area is often complex in terrain and wired communication is difficult to achieve, wireless communication technology is usually used for data transmission. The data collected by the sensor is sent to the data collection node or base station wirelessly.

[0036] The communication mode can be set up through multi-hop communication: In the sensor network, since some sensors may be located in the communication blind area, multi-hop communication is required. That is, data is transmitted step by step between sensors and finally reaches the data collection node or base station; data aggregation and forwarding: During the data transmission process, the data of multiple sensors can be aggregated to reduce the data transmission volume and improve the transmission efficiency. At the same time, the accuracy and real-time nature of the data must be ensured.

[0037] Data processing and integration, data preprocessing: cleaning, denoising and other preprocessing operations are performed on the raw data collected by the sensor to improve data quality. Data analysis: Use data analysis algorithms to analyze the preprocessed data and identify characteristic signals of rockfall activities. These characteristic signals may include vibration frequency, sound wave intensity, distance change, etc. Integrated network: Integrate the data of multiple sensors into a unified network platform to form an integrated rockfall perception network. On this platform, the data of each sensor can be comprehensively analyzed and processed to achieve real-time monitoring and early warning of rockfall activities.

[0038] System maintenance and optimization, regular maintenance: Regular inspection and maintenance of the sensor network to ensure the normal operation of the sensor and the stability of data transmission. System upgrade: With the development of technology and changes in monitoring needs, the sensor network needs to be upgraded and modified to improve the performance and reliability of the system. User training: Training system users to enable them to master the operation and maintenance skills of the system to ensure the normal operation and effective use of the system.

[0039] There are various notification methods for rockfall sensing warning information, which aims to ensure that the warning information can be quickly and effectively conveyed to relevant personnel when rockfall risks are detected, so that timely response measures can be taken. Warning information can be pushed to people or organizations concerned about the safety of the area through sound and light warnings, or SMS notifications and information push on related platforms, using the Internet and mobile application platforms. This is usually achieved through a specific monitoring and early warning system platform or the official APP of the relevant government or enterprise; In summary, there are various notification methods for rockfall sensing warning information, and each method has its unique advantages and applicable scenarios. In actual applications, a variety of notification methods can be comprehensively selected according to factors such as the specific situation of the monitoring area, personnel distribution, and early warning needs to ensure the timely and accurate communication of early warning information.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
