Semi-automatic construction control system and method for excavator

Abstract

The invention discloses a semi-automatic construction control system and method for an excavator. The semi-automatic construction control system and method solve the technical problems of low construction efficiency and low construction precision in the operation process of using the excavator for leveling and slope repairing, and the control system comprises a sensor module, a control module, a measuring module and an operating module; and the measuring module inputs measuring data into the control module, and the control module realizes calculation of the elevation, the flatness and the slope by establishing a coordinate system, meanwhile, the sensor module feeds back the condition of the excavator equipment to the control module, engineering design data are manually input into the control module, the control module transmits correction output signals which are fed back to the operating module, and the excavator enters a two-linkage semi-automatic state to complete the construction.The control system and the control method also have the advantages of low technical requirements for an excavator operator, high construction precision, no need for secondary measurement and the like.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to an excavator semi-automatic construction control system and a construction control method. Background technique [0002] With the development of the electronically controlled operating system, the foundation has been laid for the automation of the excavator. The control system structure of the excavator includes: joystick, control device, pilot control proportional valve, and the control device receives 8 operations of the left and right joysticks. In addition to the position command signal, the system control information is also transmitted to the display; each control information is used to control the 8 action pilot control proportional valves of the 4 action mechanisms such as the swing, the boom, the stick, and the bucket. At the same time, the displacement sensor and angle sensor provide real-time feedback for the action of the excavator, thereby effectively controlling ...

AI Technical Summary

Problems solved by technology

In the traditional excavator construction process, the operation under different working conditions has high requirements on the excavator operator, especially the engineering operations such as flat ground and slope repair, and the operator of the excavator is fatigued during repeated work. Finally, professional measurement is required, and there are problems such as low construction efficiency and high personnel costs
