AI Technical Summary

Technical Problem

In complex environments, laser rangefinders are susceptible to dust contamination, which can lead to wear and tear on components and affect the laser signal, thus impacting the accuracy of distance measurement.

Method used

A distance measuring device for real estate surveying was designed. A protective cover is used to cover the laser rangefinder, and a laser penetration hole is opened on the protective cover. The protective cover can slide and flip, and is equipped with a level sensor and a universal joint suction cup to ensure that the laser rangefinder can work normally in complex environments.

Benefits of technology

It effectively isolates dust pollution, ensures the normal operation and ranging accuracy of the laser rangefinder, adapts to complex environments, and supports unattended long-term data monitoring.
