A kind of semi-automatic construction control system and control method of excavator

Abstract

The invention discloses an excavator semi-automatic construction control system and control method, which solves the technical problems of low construction efficiency and low construction precision existing in the operation process of excavator leveling and slope repairing. The control system includes a sensor module and a control module , measurement module and operation module. The measurement module inputs the measurement data into the control module. The control module realizes the calculation of elevation, flatness and slope by establishing a coordinate system. At the same time, the sensor module feeds back the condition of the excavator equipment to the control module, which is manually input into the engineering design. The data is sent to the control module, and the control module transmits the feedback correction output signal to the operation module, and the excavator enters the two-linkage semi-automatic state to complete the construction. The control system and control method provided by the invention also have the advantages of low requirements on the technical level of excavator operators, high construction precision, and no need for secondary measurement.

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
