Abstract

The present invention improves a work efficiency of an entire system for operating a plurality of working machines. An operation system of the working machine includes a work progress calculating unit 80 which calculates a work progress of a plurality of working machines or a scheduled ending time calculating unit 81 which calculates a scheduled ending time of a work by using the work progress calculated by the work progress calculating unit 80. A working machine of which an operation is switched from automatic control to remote control is determined from among the plurality of working machines by using the work progress or the scheduled ending time, and the operation system includes a centralized operation controller 43 which transmits an operation instruction to the determined working machine.

Claims

1. An operation system of a working machine comprising:

a work progress calculating unit configured to calculate a work progress of a plurality of working machines;

a scheduled ending time calculating unit configured to calculate a scheduled ending time of a work by using the work progress calculated by the work progress calculating unit;

a work progress switching controller configured to compare the work progress of the plurality of machines,

wherein;

a working machine of which an operation is switched from automatic control to remote control is determined from among the plurality of working machines by using the work progress or the scheduled ending time,

the operation system includes a centralized operation controller which transmits an operation instruction to the determined working machine, and

automatic control of the determined working machine is switched to remote control based on a comparison result obtained by the work progress switching controller.

2. The operation system of the working machine according to claim 1, wherein:

the working machine controller configured to calculate the work progresses based on object information of work objects.

3. The operation system of the working machine according to claim 1, wherein:

The working machine controller is configured to calculate the work progresses based on moving route information of the plurality of working machines.

4. The operation system of the working machine according to claim 2, wherein

The working machine of which an operation is switched from automatic control to remote control is determined from among the plurality of working machines by using the work progress and the scheduled ending time.
