Laser distance measuring and height measuring device

Abstract

The invention discloses a laser distance measuring and height measuring device. An angle sensor consists of a stepping motor, a laser lamp A and a laser lamp B, wherein the laser lamp B is fixed on a bracket; the laser lamp A is fixed on the stepping motor; a singlechip control circuit and a sliding track are fixed on a triangular bracket; the sliding track is provided with an encoder and an angle sensor; a CPU (Central Processing Unit) is arranged in the singlechip control circuit, and is connected with the angle sensor, the encoder, a key, a buzzer and a liquid phase display; a fixed laser beam is aligned with a target A to be detected to obtain a reference line of an angle; the stepping motor is moved to a leftmost end; a keyboard rotating key is rotated till a laser beam controlled by the stepping motor is emitted onto a target B to be detected; the laser beam points the direction of a track gauge; the stepping motor is moved to the other end of the sliding track; the stopping motor is used for driving the encoder to record a moving distance; an LCD (Liquid Crystal Display) is used for displaying results; and if height is required to be measured, a height measuring mode is switched to. The laser distance measuring and height measuring device has the characteristics of convenience for carrying, accurate measurement and convenience for operating.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying and mapping, and in particular relates to a laser distance measuring and height measuring device. Background technique [0002] Distance measuring and height measuring devices are commonly used surveying and mapping instruments in engineering. The existing measurement technology is generally the direct measurement method, and the measurement environment is limited. It is difficult to measure the distance between two targets that cannot be directly contacted. Traditional ranging and height measuring devices need to fix a measurement reference point to complete the measurement, such as ultrasonic ranging, traditional laser ranging, etc., and are also affected by factors such as the measurement environment and geographical conditions.
