Geological disaster monitoring and early warning system Achieves 1mm-Level Displacement Monitoring and Audible/Visual Alarms Using Harmless Laser Technology

Geological disaster monitoring and early warning system utilizes harmless laser technology to continuously monitor minute displacements in building structures such as dilapidated buildings, walls, and columns from a long distance. The minimum detection value is 1mm, and the measuring range is 100 meters. The device features 9 fixed alarm thresholds and a custom setting function from 1 to 200mm. Upon triggering, it emits a 105-decibel audible and visual alarm, suitable for emergency rescue scenarios such as earthquakes, fires, and civil defense.

Geological disaster monitoring and early warning system is a high-tech safety monitoring device specifically designed for earthquake rescue scenarios. It integrates laser displacement monitoring, vibration sensing, and data analysis technologies, enabling real-time capture of minute deformations and vibration signals in building structures, providing crucial safety warnings for rescue personnel. This device uses harmless laser technology, employing dual laser beams to accurately measure the displacement of target objects. With a measuring range of up to 100 meters and a minimum detection value of 1mm, it can penetrate complex environments such as smoke and dust, monitoring minute movements of structures such as dilapidated buildings, walls, and columns in real time. When a displacement greater than 1mm is detected, the device immediately triggers an audible and visual alarm and a wireless alarm.

The Geological disaster monitoring and early warning system features an intrinsically safe explosion-proof design, enabling reliable detection in flammable and explosive earthquake rescue environments. It boasts dual-channel monitoring, allowing simultaneous monitoring of displacement changes at two locations. The device weighs 3.8 kg, has an extended height of at least 1600 mm, and is equipped with a built-in 5000 mAh polymer lithium battery, providing over 6 hours of continuous operation. Each unit features two laser emitters, offering greater accuracy compared to single-beam laser monitoring and alarm systems. The device includes a combined telescope sight for precise target positioning and supports remote control, allowing alarm values to be set wirelessly from a distance.

Regarding alarm functionality, the Geological disaster monitoring and early warning system offers nine fixed alarm thresholds: 5, 10, 15, 20, 30, 50, 70, 80, and 100 mm. The instrument includes plus and minus buttons, allowing alarm values to be set arbitrarily between 1 and 200 mm. The audible and visual alarm system features two LED flashlights and a fire alarm, delivering an alarm volume of 105 decibels. The device features a built-in 5-megapixel video display with dual 5.8cm diagonal screens; one shows the laser status, and the other shows the video status. The video image can be zoomed in and out, eliminating the need to view the target through a scope.

The Geological disaster monitoring and early warning system unit can be used standalone or in combination. Suitable for firefighting and urban rescue, this device is widely used in earthquake, firefighting, civil defense, and public security fields. The wireless transmission distance between the wireless control receiver and the laser transmitter is at least 800 meters, supporting bidirectional wireless transmission. The device supports power-on self-check and low-battery alarm functions. With its high precision and non-contact monitoring method, this device provides crucial safety assurance for rescue personnel in scenarios such as earthquake disaster relief and structural health monitoring.
