Displacement (Aftershock) Monitor

Brand: Sheng Bolan

Model: BF-JG/YZ5.0

  In response to the recent surge in natural disasters both domestically and internationally, and the ongoing threat to rescue teams’ safety posed by secondary collapses of buildings during search-and-rescue operations, our company has invested heavily in scientific research and testing, independently developing an alarm system that provides early warnings of potential hazards such as loosening or collapse of walls caused by aftershocks from earthquakes or explosions, dilapidated buildings, sinking of structural beams, lateral displacement of metal containers, or collapse of glass walls. This system immediately triggers an alarm at the very first sign of movement, promptly alerting rescue personnel to evacuate to a safe zone, thereby effectively safeguarding their personal safety.

1. An alarm system used for early warning of potential issues such as wall loosening and collapse, settlement of building beams, lateral displacement of metal tanks, or wall collapse;

2. Utilizing harmless lasers, it can detect even the slightest movements in structurally compromised buildings and other architectural elements—such as floors, floor tiles, columns, and walls—that are caused by earthquakes, bombs, gas explosions, and other similar events.

3. Integrates laser-based remote monitoring with tilt and vibration monitoring to provide real-time monitoring of displacement and angular changes.

4. Supports remote control functionality; alarm thresholds can be set wirelessly from a long distance.

5. Supports a one-click reverse search function, enabling the laser displacement host and the aftershock host to trigger alarms simultaneously.

An alarm system designed for early warning of potential issues such as wall loosening and collapse, settlement of building beams, lateral displacement of metal tanks, or wall collapse.

1. The complete system consists of a laser displacement main unit, a tripod, a handheld wireless control receiver, at least 3 aftershock monitors (with the option to add 1–8 additional units), an audio-visual alarm, and a safety protection box, among other components.

2. Laser Host: The laser emitter has a monitoring range of 100 meters and emits two laser beams. The laser alarm threshold supports two modes: a fixed alarm value and an arbitrarily set alarm value. The minimum detectable laser value is 1 mm. When the displacement of the laser host exceeds the preset value, it will trigger both an audible and visual alarm. The device is equipped with at least two LED lights. The maximum sound level of the alarm is 110 dB, and the alarm sound is adjustable.

3. Aftershock Host: Aftershock measurement range: three-dimensional (360 degrees), capable of monitoring and displaying the X, Y, and Z axes in a 3D立体 manner. Aftershock host alarm functions: 6 LED flashing lights, fire alarm sound ≥100 dB, and adjustable alarm volume.

4. The handheld wireless control receiver features a color touch screen with a diagonal size of ≥10 inches (≥25.5 cm), a wireless transmission range of ≥600 m, and the ability to receive laser irradiation distance and laser alarm status information.
