Description

Technical Field

[0002] During the construction of power systems and when measuring the area and length of power construction sites, a field measurement device for power construction is used for testing. The field measurement device for power construction is an infrared rangefinder, also known as a laser rangefinder. When infrared light is emitted from the rangefinder and hits a reflective object, it is reflected back and received by the rangefinder. The distance can then be calculated based on the time from the emission to the reception of the infrared light and the propagation speed of the infrared light. Most laser rangefinders in the existing technology are used by hand or with a tripod. When using a laser rangefinder by hand, the stability during use cannot be guaranteed, which will cause measurement deviations. When used with a tripod, the tripod itself is large and not easy to carry. For this reason, we have proposed a distance measurement device for power construction. Utility Model Content
