early alarm and forecasting of disasters

The regional geological hazard monitoring system is an integrated system to monitor space, ground surface and underground area through data collection, transmission, analysis and treatment. It can establish a monitoring network covering air, ground surface and underground, i.e. the so-called “three-net”.The system makes full use of geological parameters collected by high precision inertial sensor in sensitive rock soil, such as subtle displacement, distortion, and vibration, and combines them with ground or underground parameters collected by other sensors such as temperature, electric resistance and rainfall. Then before any hazard happens, it automatically gathers such feature information, transmits it via network to the database for storage and carries out processing and analysis. Thus it can realize distributed sharing of geological data in a region and even the whole country.

Feature

It supports integration with many common monitoring sensors to realize automatic monitoring, such as fixed inclinometer, udometer, crack displacement meter, pore water pressure meter, soil pressure meter and so on.

It has flexible working manner, and supports timed reporting, real-time measurement, threshold startup and some other modes.

It supports wire communication and such wireless communications as GPRS, Beidou satellite navigation and digital transmission radio.

It can remotely monitor and manage the on-site equipment.

With linked responding of on-site monitoring sensor, it can realize triggering of related sensors by one sensor.

Advanced technology

Standardized and modular design, leading to flexible networking and high expandability.

Adaptability to all-weather outdoor environment, and high reliability.

Low power consumption and allowing diversified power supplies.

Comprehensive data processing and output in various charts and forms; database retrieval by landmark, time, parameter type and so on; dynamic WEB release.

Sound-light alarm and short message alarm.

Application fields

It helps to estimate and judge the change trends of hazard factors such as landslip and mudflow which realizes early alarm and forecasting of disasters.
