An unmanned auxiliary driving system for an external road roller

Abstract

The present invention is an unmanned assisted driving system for an external road roller. The output terminals of the sensors are all connected to the on-board data box; the on-board data box is connected to the auxiliary controller; the steering wheel of the cab is connected to the steering hydraulic mechanical arm through the first transition part, and the gear position of the cab is connected to the gear hydraulic pressure arm through the second transition part. Mechanical arm; the chassis is equipped with a vehicle-mounted data box and an auxiliary controller, and the auxiliary controller is electrically connected to the control switch, the steering hydraulic mechanical arm, the gear hydraulic mechanical arm, and the front and rear millimeter-wave radars; the control switch is connected in parallel On the vibration switch of the vibration control circuit of the manned road roller. Aiming at the unmanned shortcut modification of the ordinary road roller driven by the driver, the unmanned driving of the ordinary road roller is realized.

Description

technical field [0001] The invention relates to the technical field of an unmanned auxiliary driving system for an externally mounted road roller. Background technique [0002] Unmanned road rollers proposed in road construction at this stage usually control their internal oil circuit structure to achieve vibration control, travel control, steering control and braking control of the road roller. This type of unmanned road roller has its limitations, usually For the road roller manufacturer, the unmanned control system is integrated and packaged inside the chassis of the road roller, so as to realize the unmanned driving of the road roller. [0003] For example, Xia Panfu et al. (Xia Panfu, Gao Liang. Discussion on the design of unmanned road rollers [J]. Road Construction Machinery and Construction Mechanization, 2019, 36(06): 22-26.) gave an unmanned road roller In the design discussion, the electronic control hardware is preferred to the mechanical hardware in the executi...

AI Technical Summary

Problems solved by technology

This technology limits the concept of unmanned driving to the unmanned road rollers produced by the manufacturers, and is not universal. In the project, more ordinary road rollers driven by ordinary drivers and repeated rolling operations in the construction area are used. In order to realize the unmanned driving function of this type of roller with the above method, it is necessary to make major changes to the oil circuit and circuit of the roller chassis, and to package the controller inside the chassis of the roller to realize unmanned control, which is costly and time-consuming, and is not applicable , and for different types of road rollers, the internal oil circuit packaging methods are different, and the modification methods are also different, so it is difficult to implement

And this kind of scheme is more applied to the design scheme of the unmanned road roller that leaves the factory, and it is less applied to the modification of ordinary road rollers
