2. Technical Difficulties
A. Weak Signal Capture
The acoustic emission signal inside the collapse body is often extremely weak and easily interfered by environmental noise. The instrument adopts high-precision, low-noise sensor components, combined with advanced signal amplification and filtering technology, realizing the accurate capture and identification of weak acoustic emission signals.
B. Complex Environment Adaptability
Collapses occur in complex and changing natural environments, and factors such as temperature, humidity and electromagnetic interference may affect the performance of the sensors. Our acoustic emission monitoring and early warning instrument is encapsulated with special materials and intelligent calibration algorithms to ensure that it can work stably in various harsh environments and maintain high sensitivity and accuracy.
C. Real-time Data Processing
Real-time processing and analysis of massive data is the key to collapse monitoring and early warning. Acoustic emission monitoring and early warning instrument integrates high-performance embedded processing chip and optimized algorithm model, which realizes rapid data acquisition, processing and uploading, and provides the possibility of rapid response.
3. The Product Features Highlights
A. High-precision Monitoring
Adopting advanced acoustic emission detection technology, it is able to capture the extremely weak acoustic signal changes inside the collapse body, providing data support for accurate early warning.
B. Remote Real-time Monitoring
Supporting wireless remote data transmission, users could check the monitoring data in real time through the cloud platform, and master the operation status of the collapse body anytime and anywhere.
C. Intelligent Early Warning System
Intelligent algorithm can automatically analyze the monitoring data and trigger the early warning mechanism as soon as the abnormality is found, and notify the relevant personnel through SMS, email and other ways.
D. Strong Durability
Waterproof, dustproof, shockproof design, it adapts to various harsh environments, to ensure long-term stable operation.
In order to ensure the reliability and stability of the product, our second-generation acoustic emission monitoring and early warning instrument has been subjected to several rounds of multi-dimensional rigorous testing in the laboratory of the China Three Gorges University, including the long-term operation test under simulated different geological conditions, the extreme environmental adaptability test, and the comparison and validation of data with the actual collapse events. Each test was carried out in strict accordance with national standards to ensure the stable and reliable operation of the acoustic emission monitoring and warning instrument in real application scenarios.

A. Laboratory Simulation Tests
During the R&D process, a comprehensive simulation test was first carried out in the laboratory environment. By simulating the acoustic emission signals under different geological conditions, the acoustic emission monitoring and warning instrument's ability to capture weak signals and the accuracy of signal processing were verified. The test results show that the acoustic emission monitoring and early warning instrument can accurately recognize and extract effective acoustic emission signals under high noise background with very low error rate.
B. Field test
In order to verify the performance of the acoustic emission monitoring and early warning instrument in the real environment, our company chose a number of representative geological disaster-prone areas for field testing, covering a variety of geological conditions and climatic environments. During the test period, the acoustic emission monitoring and warning instrument successfully captured the small changes inside the geologic body many times. These early warning messages were highly consistent with the actual observation results, which verified the high sensitivity and reliability of the acoustic emission monitoring and early warning instrument.
