The displacement monitoring instrument is a high-precision, multi-functional monitoring device designed specifically for emergency rescue scenarios, which can monitor small displacement changes of buildings, geological structures, etc. in real time, provide key data support for rescue decisions, and effectively ensure the safety of rescue personnel. The emergency rescue displacement monitoring device captures real-time displacement changes of the target object, including horizontal displacement, vertical displacement, and tilt angle, through high-precision sensors such as laser ranging sensors and GNSS receivers. For example, a laser displacement monitor can emit a harmless laser beam to irradiate the surface of the object being measured, receive the reflected light, and calculate the displacement change of the object based on the optical path difference; GNSS displacement monitoring devices use navigation satellite systems (such as GPS) for positioning measurement, and calculate the precise coordinate information of surface points by receiving satellite signals, thereby monitoring the horizontal and vertical displacement of the surface. The measurement accuracy of the high-precision displacement monitoring instrument can be ≤ 1mm, which can quickly capture small displacement signals of the structure with negligible errors.

9. Equipped with two display screens, one for laser and the other for video status. Display Screen 1: It can display the laser irradiation distance, alarm threshold, device battery level, and alarm status; Display Screen 2: It can display the monitored target object in real time, and can be turned on/off through independent buttons. The diagonal size of the display screen is ≥ 6cm.

10. The alarm threshold can be adjusted as needed, supporting two methods: fixed alarm values and arbitrary setting of alarm values. The tilt angle monitor can set 7 fixed alarm thresholds of 0.5 °, 1.0 °, 2.6 °, 5.0 °, 8.0 °, 10.0 °, 20.0 ° through shortcut keys, and can also be set in steps of 0.1 °. The adjustable range is 0.1-90 °, and any scale value can be continuously adjusted. The displacement monitoring instrument can set 9 fixed alarm thresholds through shortcut keys: 5, 10, 15, 20, 30, 50, 70, 80, 100mm, and can also be set in steps of 1mm. The adjustable range is 1-9999mm, and any scale value can be continuously adjusted. ▲

When the monitoring value deviates from the set value, an automatic alarm can be triggered, emitting an audible and visual alarm signal, and the alarm signal can be manually released by pressing the button. The control terminal (host) can achieve linked alarm monitoring with various monitoring instruments.

12. The alarm sound intensity is ≥ 120dB, and the alarm sound can be turned on and off.
