The invention discloses an excavator electronic enclosure wall configuration method, an excavator controller and an excavator. The excavator electronic enclosure wall configuration method comprises the steps that when an upper rotary table of the excavator is located at a calibration position, a calibration point of an excavator bucket is determined; and coordinates of the calibration point underan excavator coordinate system are determined, the position of an electronic enclosure wall surface is determined according to the coordinates, the origin of the coordinates of the excavator coordinate system is a gyration center point connecting the upper rotary table and a lower rotary table of the excavator, and the wall surface is a plane. According to the electronic enclosure wall configuration method, the position of the electronic enclosure wall surface is determined through the coordinates of the calibration point, compared with an electronic enclosure wall based on a rotation angle, the area surrounded by the electronic enclosure wall configured through the method is larger, and when the posture of the excavator changes, the excavator can rotate by a larger angle, a larger workingrange is obtained, and the working efficiency is further improved.
