Abstract

The invention provides an automatic driving system and method of a water conservancy construction vibration roller. The system comprises a remote monitoring device and an onboard automatic control device. The remote monitoring device plans working areas and navigation routes according to 3D digital model man-machine interaction of construction projects, receives data like position, speed and rotation direction of the roller and working environment video information in a wireless communication manner and sends automatic navigation data and instructions to the onboard automatic control device. The remote monitoring device can also remotely control the roller based on received emergent processing requests in a man-machine interaction manner. The onboard automatic control device receives the automatic navigation instruction and remote control driving information sent by the remote monitoring device in real time, and compares the information sent by the onboard automatic control device with the information like position, speed and rotation angle detected by an onboard RTK-GPS and a sensor. After being adjusted via the PID algorithm, deviation is sent to execution elements like an electric steering wheel, an electric throttle and an electric brake to control the vibration roller to finish respected rolling work. According to the invention, the automatic driving system is compatible with a manual driving system.

Description

technical field [0001] The invention belongs to the technical field of water conservancy construction machinery, and in particular relates to an automatic driving system and method for a vibratory rolling machine in water conservancy construction. Background technique [0002] The construction of water conservancy projects in my country has been mechanized. For earthwork, roller compacted concrete and other filling projects, vibratory roller compactors have been widely used due to their advantages of good compaction effect and high production efficiency. However, the construction process of water conservancy projects is complicated, the working conditions are poor, and the operation is monotonous and boring. Operators of vibratory rollers are prone to operating errors or errors, resulting in insufficient compaction density of dam materials on the working surface, which affects the construction quality. [0003] In order to reduce the labor intensity of vibratory roller opera...
