Method for establishing electronic fence for excavator

Abstract

The present disclosure relates to a method for establishing an electronic fence for an excavator, wherein the excavator includes a frame, a slewing platform rotatably mounted on the frame, a working arm mounted on the slewing platform in a pitching swinging manner, and a bucket rotatably mounted on the working arm. The working arm includes a first working arm hinged to the slewing platform and a second working arm hinged to the first working arm. An end, away from the first working arm, of the second working arm is hinged to the bucket. The method includes: establishing a three-dimensional coordinate system including an X-axis, a Y-axis, a Z-axis, and an origin O; and obtaining boundary lines of working areas of the working arm and the bucket of the excavator in a same height plane in the three-dimensional coordinate system, including: obtaining coordinates, in the three-dimensional coordinate system, of multiple boundary points of the working areas at the same along a circumferential direction of the excavator; and connecting two adjacent boundary points to form multiple straight lines connected in sequence, and taking the boundary lines formed by the multiple straight lines as the electronic fence.
