Structural Health Monitor

1.Introduction to Structural Health Monitor Products

Structural Health Monitor monitors the tilt and displacement of structures such as highway overpasses, roads, buildings, fixed walls, bridges and amusement parks.Based on the principles of high precision, low power consumption, stability and reliability, an integrated inclined attitude monitor was designed and developed.It can combine intelligent gateways, alarm equipment and IoT platforms to form a closed-loop system of self-power, self-monitoring, self-analysis, and self-alarming for geological disaster potential points, and is suitable for intelligent and universal monitoring and early warning of geological disasters.

2.Product features of Structural Health Monitor

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

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

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

4.High precision: adopts on-site redundant observation, based on the prior error and actual measurement error, embedded edge calculation, data filtering and data cleaning algorithms, realizes rough error removal and abnormal detection, ensures the reliability of monitoring data, and meets the requirements of relevant technical standards;

5.The hot melt embedded installation nut on the back of the mainframe housing is designed with a fitting design, and the built-in high-performance housing integrated power-replenishing solar panels are used.It adopts a pole-type installation and deployment, which is easy to install and deploy.

Applicable areas

It is suitable for monitoring fields such as geological disasters, geotechnical engineering, construction engineering, transportation, water conservancy, and municipality, and is used to monitor real-time monitoring of high-frequency structure vibrations and small tilt changes in geological disasters.
