Curb detection system, method, device and construction machinery

Abstract

The invention relates to the technical field of engineering machinery measurement and control, discloses a curb detection system, method and device and engineering machinery, and aims to improve curb detection reliability and accuracy. The curb detection system comprises a laser sensor and a control device, the laser sensor is used for uniformly transmitting a plurality of ranging laser beams towards a curb side within a set included angle and recording a measuring distance and a sequence corresponding to each ranging laser beam, and the control device is connected with the laser sensor through a signal and used for acquiring a corresponding relation between the measuring distance and the sequence according to the measuring distance and the sequence of each ranging laser beam, judging whether the ranging laser beams radiate to a target curb or not according to the corresponding relation between the measuring distance and the sequence, and acquiring the horizontal measuring distance between the laser sensor and the target curb according to the measuring distance of the ranging laser beams radiating to a curb root when the ranging laser beams radiate to the target curb.

Description

technical field [0001] The invention relates to the technical field of construction machinery measurement and control, in particular to a curb detection system, method, device and construction machinery. Background technique [0002] The curb is the boundary stone set on the edge of the road, which serves as the boundary between the road and other areas. The height of the curb usually ranges from 15 cm to 30 cm. When construction machinery works along the edge of the road, it is necessary to control the horizontal distance between the construction machinery and the curb. In the prior art, ultrasonic equipment or single-point laser equipment is mainly used to detect the horizontal distance from the construction machinery to the curb, and the installation height of the ultrasonic equipment or single-point laser equipment usually does not exceed the height of the curb. [0003] The defect of the prior art is that, due to the relatively limited installation position of the ult...

AI Technical Summary

Problems solved by technology

[0003] The defect of the prior art is that, due to the relatively limited installation position of the ultrasonic equipment or single-point laser equipment, it is easy to be damaged by obstacles on the road, and the reliability is poor, and the detection accuracy is also affected by the interference of obstacles Poor, which seriously affects the operating efficiency of construction machinery
