In recent years, extreme natural disasters have occurred frequently around the world. Events such as earthquakes, landslides, and forest fires have put forward higher requirements for the accuracy and timeliness of emergency rescue. Data collection and decision-making support at the disaster site have become the key to the success of rescue operations.
The rescue site often faces challenges such as smoke, rain, snow, and vegetation obstruction. Traditional measuring tools are difficult to meet the needs due to problems such as low efficiency and large errors. Distance meters have a protection level of IP65 or above, and they support measuring the real surface information of the earth through the gaps in vegetation, and can adapt to extreme conditions such as nighttime and high temperatures. For example, the airborne LiDAR technology penetrated the forest cover during the Jiuzhaigou earthquake and identified potential high-position landslide hazards. The non-contact measurement method reduces the risk of rescue workers directly entering dangerous areas, effectively protecting the lives of rescue team members.
After an earthquake occurs, the rescue team uses a laser distance meter to measure the inclination of buildings and evaluate the structural stability, providing a safe rescue environment for rescue workers. At the same time, the laser distance meter is used to measure the thickness of the ruins to formulate a reasonable rescue plan.
The laser distance meter can respond quickly, rapidly obtain key data on the site, and shorten the time for rescue decision-making and implementation. At the same time, the high-precision measurement of the laser distance meter provides a scientific basis for subsequent structural safety assessment and post-disaster reconstruction planning, reducing the uncertainty in the rescue and recovery process. In addition, it is suitable for disaster rescue in multiple fields such as construction, geology, and transportation, demonstrating wide applicability and market potential.
With its characteristics of being fast, efficient, and accurate, the laser distance meter plays an irreplaceable role in disaster rescue. As its application scenarios continue to expand, its role in data support, structural assessment, and environmental monitoring at the rescue site will become more prominent.
