Position and posture parameter measuring system and method for machine body of tunneling machine through linear light spot recognition

Abstract

The invention relates to a position and posture parameter measuring system and method for a machine body of a tunneling machine. The system comprises a laser emitter, a laser detection target, a laserdetection target plate, a single chip microcomputer, a subsequent connecting circuit, an output interface and a double-axis inclined angle sensor, wherein the laser emitter gives out fan-shaped laserbeams capable of being projected into linear light spots; the laser detection target is vertically arranged on the machine body of the tunneling machine; the offset displacement of the machine body of the tunneling machine can be known according to the scale value reading of the located position of the linear light spots formed by the projection on the laser detection target; the laser detectiontarget plate formed by light-sensitive detection element dot matrixes is flatly laid and arranged on the machine body of the tunneling machine; and the offset displacement and course angle parametersof the machine body of the tunneling machine can be known through the transverse and longitudinal scale value readings of the linear light spots formed by the projection on the laser detection targetplate. The pitch angle and roll angle parameters of the machine body of the tunneling machine are obtained through the measurement by using the double-axis inclined angle sensor arranged on the machine body of the tunneling machine, so that the measurement on each position and posture parameter of the machine body of the tunneling machine can be completed.

Description

technical field [0001] The invention relates to a position recognition system in the field of measurement and positioning, in particular to a position and posture parameter measurement system of a roadheader fuselage in the field of laser detection and recognition systems. Background technique [0002] Measurement and positioning technology is inseparable from human practical activities, and it is also constantly developing and changing with the progress of society. [0003] Since the 1950s, measurement and positioning technology has begun to develop in the direction of electronization and automation. With the emergence of various light sources (laser, infrared light, etc.), the physical distance measurement technology has also been developed rapidly, and there have been light wave range finders with laser, infrared light and other light sources as carriers and microwave as carrier waves. The emergence of microwave rangefinder and electromagnetic wave rangefinder is a revol...
