Remote control system and main control device

Abstract

A master 20: acquires, from a slave 10, a surrounding image G31 on which the periphery of a construction machine 30 is photographed from the inside of an operation seat 3C of the construction machine30; determines whether the surrounding image G31 includes an image of a working device 330; calculates the position of the working device 330 from the orientation of the construction machine 30, whenthe image of the working device 330 is not included in the surrounding image G31; and displays, on a display device 23, a display object OBX for notifying an operator of the calculated position together with the surrounding image G31.

Description

technical field [0001] The present invention relates to a remote operating system and the like provided with a master operating device and a slave operating device. Background technique [0002] In recent years, there has been known a remote operating system that remotely operates a construction machine by using a master operating device called a master that directly accepts an operator's operation and a slave operating device called a slave that is communicably connected to the master (for example, Patent Document 1). [0003] In such a remote operating system, the surrounding image of the construction machine taken by the camera installed in the operator seat of the construction machine is displayed on the display device installed in the host computer, and the operator monitors the construction machine while viewing the surrounding image displayed on the display device. Mechanical operating devices (booms, sticks, buckets, etc.) are remotely operated. [0004] In additio...

Problems solved by technology

[0005] However, depending on the posture of the working machine, the working machine may be outside the field of view of the camera installed in the operator's seat.

At this time, the working device disappears from the surrounding image displayed on the display device of the main unit, and the operator of the main unit cannot confirm in which direction the working device is currently located, causing the operator to feel uneasy.

[0006] In particular, when restarting the remote operation of the construction machine after a break such as a lunch break, if the work equipment does not appear in the surrounding image, the operator is required to predict the position of the work equipment and carefully operate the work equipment, which has a problem of increasing the operational burden.

[0007] The aforementioned Patent Document 2 is not originally an invention related to the remote operating system, nor does it disclose that a camera is installed in the operator's seat, which cannot solve the above-mentioned problem that occurs when the operating device disappears from the surrounding image displayed on the display screen of the host computer. question
