Problems solved by technology

However, since various display devices are installed in the driver's seat, the vial level may be hidden by the display device.
In such a case, in order to recognize the tilted state of the work machine with the vial level, the operator needs to change his posture, resulting in poor workability

Embodiment Construction

[0132] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0133] The overall structure of the working machine

[0134] figure 1 It is a perspective view of a working machine provided with a display system displaying a monitor display level according to the present embodiment. A hydraulic excavator 100 as an example of a working machine has a vehicle body 1 and a working machine 2 as a main body. The vehicle main body 1 has an upper revolving body 3 as a revolving body and a traveling device 5 as a traveling body. The revolving superstructure 3 accommodates devices such as an engine and a hydraulic pump inside the engine room 3EG.

[0135] The upper revolving structure 3 has a cab 4 . The cab 4 is provided on the other end side of the upper revolving structure 3 . That is, cab 4 is provided on the side opposite to the side where engine room 3EG is arranged. In cab 4, the configuration is as follows figure 2 The display ...

Abstract

In order to provide a work machine, and a display system for a work machine for displaying a monitor display spirit level that enables an operator of the work machine to precisely ascertain the tilt and direction of the work machine as required, the present invention is provided with: an IMU (24), which is a tilt sensor for detecting the pitch angle and the roll angle of a hydraulic excavator (100); a calculating unit (31) for calculating the tilt position on polar coordinates that indicate the magnitude of the tilt and the direction of the tilt of the hydraulic excavator (100) based on the pitch angle and the roll angle detected using the IMU (24); a display processing unit (32) for displaying a monitor display spirit level (40) in a specific area on a screen of a display unit (29) installed in the hydraulic excavator (100), the monitor display spirit level (40) displaying the polar coordinates of the tilt position and a reference line indicating the magnitude of a preset tilt; and a settings processing unit (33) for changing and setting what is displayed by the monitor display spirit level (40).

Description

technical field [0001] The present invention relates to a display system of a working machine capable of displaying a monitor display level that enables an operator of the working machine to recognize the inclination and direction of the working machine with high precision as required, and the working machine. Background technique [0002] Conventionally, in working machines such as hydraulic excavators and bulldozers, a bubble tube level is installed on the driver's seat. Furthermore, when the work machine is used to level the footing, the inclination state of the work machine is recognized with reference to the vial level. However, since various display devices and the like are arranged in the driver's seat, the vial level may be hidden by the display device. In such a case, in order to recognize the tilted state of the work machine with the vial level, the operator needs to change his posture, resulting in poor workability. [0003] Patent Document 1 discloses a display...
