Structural Health Monitor

1.Structural Health Monitor Product Introduction

Based on the principles of high precision, low power consumption, stability and reliability, an integrated tilt attitude monitor was designed and developed. It can be combined with intelligent gateways, alarm equipment and the Internet of Things platform to form a closed-loop system of self-power supply, self-monitoring, self-analysis and self-alarm for geological disaster risk points, which is suitable for intelligent and universal monitoring and early warning of geological disasters.

2. Structural Health Monitor Product Features

1. High integration: It integrates MEMS acceleration module to realize three-axis acceleration and three-axis inclination observation functions, and collects ambient temperature for temperature compensation;

2. Multi-communication: It integrates 2/4G full-network public network communication, supports NB-IoT narrowband Internet of Things communication, and supports LoRa local area self-organizing network communication, realizing local area networking of monitoring equipment, regional release of early warning information, remote transmission of monitoring data, and remote control of equipment;

3. Low power consumption: Adhering to the design concept of high integration and low power consumption, it realizes the integrated design of sensing, collection, communication and power supply. The standby performance meets the needs of long-term use in the field and has the characteristics of easy installation, which is particularly suitable for emergency monitoring deployment;

4. High precision: Adopting on-site redundant observation, based on a priori mean error and measured mean error, embedded edge computing and data filtering and data cleaning algorithms, it can achieve gross error elimination and anomaly detection, ensure the reliability of monitoring data, and meet the requirements of relevant technical standards;

5. The back of the host shell is hot-melt embedded with mounting nuts and adopts a fitted design. The built-in high-performance shell integrates the power-supply solar panel and adopts a pole-mounted installation, making the overall installation and deployment simple.

Application Areas

It is suitable for monitoring fields such as geological disasters, geotechnical engineering, construction engineering, transportation, water conservancy, and municipal administration, and is used for real-time monitoring of high-frequency vibrations of structures and micro-tilt changes of geological disaster bodies.
