Plate brush system capable of automatically adjusting pressure and position based on road condition recognition

Abstract

The invention discloses a plate brush system capable of automatically adjusting pressure and position based on road condition recognition, which can recognize different road adhesion coefficients and garbage levels according to a target detection platform, and utilizes a servo motor pump control system to change the torque of a servo motor to automatically adjust the grounding pressure of a disc brush in real time, and the self-adaptive adjustment work of the sweeping vehicle disc brush in a specified stage is realized by utilizing the pressure maintaining characteristic; meanwhile, the distance between the disc brush and the road edge stone can be recognized and detected, and the sweeping operation of the disc brush bristles attached to the road edge is achieved through a displacement adjusting system; in addition, the range of the concentration degree of garbage on the road surface can be recognized, position change of the disc brush system in the direction perpendicular to the advancing route is achieved through the displacement adjusting system according to different position information, and automatic avoidance of roadside obstacles is achieved according to the roadside obstacle position information.

Description

technical field [0001] The invention relates to a disc brush system and method for automatic adjustment of pressure and position based on road surface recognition, and belongs to the technical field of intelligent control of sweeping vehicles. Background technique [0002] With the increasingly stringent emission regulations, in response to the "Blue Sky Defense War", sanitation vehicles, which play an important role in municipal management, have implemented the National VI standard. As one of the main models of urban sanitation vehicles, the sweeper has a set of cleaning functions for cleaning, garbage collection and transportation. Sweeping vehicles have greatly reduced the labor intensity of sanitation workers. Today, when electric sweeping vehicles have become a development trend, it has also brought development to the application of intelligence in cleaning vehicles. [0003] At present, the grounding pressure of the disc brush is one of the factors affecting the clean...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing insufficient adjustment of the grounding pressure of the disc brush; the uncertainty of realizing the cleaning operation of the disc brush bristles attached to the roadside stones by the driver's operation; it is impossible to realize that the disc brush is perpendicular to the road rubbish according to the concentration density and position of the road surface rubbish. Change the position in the driving direction and automatically avoid obstacles of the disc brush. A disc brush system based on road condition recognition pressure and automatic position adjustment is proposed, which solves the cumbersome and large adjustment errors during manual adjustment. The disc brush system cannot adjust the grounding pressure according to the real-time road conditions. The subjective judgment of the driver cannot accurately make the disc brush bristles stick to the roadside stone for cleaning operations, and the disc brush cannot realize the disc brush in a direction perpendicular to the driving according to the concentration density and position of road garbage. Change the position in the direction, liberate the rear disc brush and realize the non-impact automatic obstacle avoidance of the disc brush, improve the cleaning efficiency, intelligent degree, energy utilization rate of the sweeper, slow down the wear of the disc brush bristles, and prolong the life of the disc brush.
