Structural Health Monitor

1. Structural Health Monitor product introduction

Structural Health Monitor is a tilt monitoring instrument used to monitor the horizontal or vertical tilt of structures and soil.Based on the principles of high precision, low power consumption, stability and reliability, an integrated tilt attitude monitor is 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 hazard points, which is suitable for intelligent and universal monitoring and early warning of geological disasters.

2.Product features of Structural Health Monitor

1.High integration: Integrated MEMS acceleration module to realize three-axis acceleration and three-axis inclination observation functions, while collecting ambient temperature for temperature compensation;

2.Multi-communication: Integrate 2/4G full network public network communication, support NB-IoT narrowband Internet of Things communication, and support LoRa local ad hoc network communication to realize local networking of monitoring equipment, regional release of early warning information, and remote transmission of monitoring data , equipment remote control;

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.It has the characteristics of convenient installation and is especially suitable for emergency monitoring and deployment;

4.High precision: Using on-site redundant observations, based on a priori errors and measured errors, embedded edge calculations, data filtering and data cleaning algorithms can achieve gross error elimination and anomaly detection, ensuring the reliability of monitoring data and meeting relevant requirements.requirements of technical standards;

5.The back of the main unit casing is embedded with hot-melt mounting nuts and adopts a fit-fitting design.The high-performance casing integrates power-supply solar panels and is installed on a pole, making the overall installation and deployment simple.

Applicable fields

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.
