The Automatic Control System for The Touchdown Pressure of Disc Brush Based on Fuzzy Sensing Technology

In the daily cleaning process, the workload of the cleaning vehicle is large, leading to fast wear of the disc brush, so that the touchdown pressure of disc brush decreases. The staffs need to adjust the hydraulic oil cylinder by hand frequently according to the wear of the disc brush to compensate it. The operation of this process is comparatively complicated, it is unfavorable to improving the efficiency of the work. This study combines the structural characteristics of the cleaning vehicle and the application of sensor technology, making disc brush adjust the touchdown pressure autonomously to reduce the poor cleaning effect because of the lack of the touchdown pressure when it can't work normally due to a large change in the touchdown pressure and enhance the cleaning efficiency of cleaning vehicle. The result shows that the self-control of the touchdown pressure of disc brush system can greatly improve the cleaning efficiency of the cleaning vehicle when the continuous working time of the cleaning vehicle exceeds 4h.
