Positioning system and method for engineering machine

Abstract

The invention discloses a positioning system for an engineering machine. The positioning system comprises a light source (2), an optical sensor (1), a mechanical arm (4) and a control device (3), wherein the light source (2) is arranged at a fixed position and is used for providing a light beam of the fixed position; the optical sensor (1) is used for sensing a light beam irradiating position andconverting a position signal of the light beam into an electrical signal; one end of the mechanical arm (4) is arranged on a machine body of the engineering machine, and the other end of the mechanical arm (4) can be positioned freely; the optical sensor (1) is arranged at the free end of the mechanical arm (4); the mechanical arm is further provided with a measuring component for measuring the position of the optical sensor (1); and the control device (3) is connected to the optical sensor (1) and is used for receiving a signal transmitted by the optical sensor (1) and acquiring the pose parameter of the engineering machine. The positioning system has a flexible and convenient positioning process and is convenient and easy to operate. The invention discloses a positioning method of an engineering machine, which can be used for realizing equipment positioning and has simple steps.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a positioning system for construction machinery. The present invention also relates to a positioning method for the construction machine mentioned above. Background technique [0002] With the rapid development of economic construction, various large-scale projects in our country are increasing day by day, and the demand for construction machinery in the market is also becoming stronger and stronger. Tunneling equipment is commonly used construction machinery. [0003] Commonly used excavation equipment mainly includes rock drills and roadheaders. Whether it is a rock drill or a roadheader, the prerequisite for automatic drilling and automatic excavation is to accurately position the equipment on the center plane of the tunnel or roadway, that is, as soon as possible. It is possible to make the longitudinal section of the equipment coincide with the middle plane ...

Problems solved by technology

[0007] However, in the above-mentioned positioning system, the position of the line laser transmitter 2' is adjusted by the frame 3'. Since the frame 3' is fixed on the roof of the roadway, its position is much higher than the equipment itself, so the precise positioning of the frame 3' It is difficult to operate to achieve precise positioning of the line laser emitter 2', which makes the entire positioning process very complicated and the accuracy is not high
