Operation Control Method

Abstract

An operation control method for controlling operation of a plurality of construction machines that perform excavation while moving is described. Because a moving speed of a second construction machine at a time of excavation and an excavation time of the second construction machine are set based on a moving speed of a first construction machine at a time of excavation and an excavation time of the first construction machine, it is possible to achieve efficient excavation work with good usability.

1 . An operation control method for controlling an operation of a plurality of construction machines that perform excavation while moving, the method comprising
 setting a moving speed of a second construction machine at a time of excavation and an excavation time of the second construction machine based on a moving speed of a first construction machine at a time of excavation and an excavation time of the first construction machine.   
     
     
         2 . The operation control method according to  claim 1 , wherein
 the first construction machine includes a first scraper that performs the excavation,   the second construction machine includes a second scraper that performs the excavation, and   an amount by which the first scraper digs into a ground surface and an amount by which the second scraper digs into the ground surface are controlled to be the same.   
     
     
         3 . The operation control method according to  claim 1 , comprising
 a moving process of moving from an excavated area where the excavation is performed to a scattered area where an excavated object obtained by the excavation is scattered,   wherein a moving time of the first construction machine and a moving time of the second construction machine in the moving process are set to be the same.   
     
     
         4 . The operation control method according to  claim 3 , wherein a moving speed of the first construction machine and a moving speed of the second construction machine in the moving process are set to be the same. 
     
     
         5 . The operation control method according to  claim 1 , comprising:
 a moving process of moving from an excavated area where the excavation is performed to a scattered area where an excavated object obtained by the excavation is scattered;   a discharging process of discharging the excavated object at the scattered area; and   a redirection process of redirection from the scattered area to the excavated area,   wherein the second construction machine is controlled such that time required for each of the moving process, the discharging process, and the redirection process of the first construction machine is equal to time required for each of the moving process, the discharging process, and the redirection process of the second construction machine.   
     
     
         6 . The operation control method according to  claim 5 , wherein the moving speed of the second construction machine is controlled such that the moving speed of the first construction machine in each of the moving process, the discharging process, and the redirection process is equal to the moving speed of the second construction machine in each of the moving process, the discharging process, and the redirection process. 
     
     
         7 . The operation control method according to  claim 1 , wherein operation of the second construction machine is controlled in an unmanned manner. 
     
     
         8 . The operation control method according to  claim 1 , comprising:
 obtaining data concerning a drive of the first construction machine; and   applying the data to excavation on the following day and thereafter.   
     
     
         9 . The operation control method according to  claim 8 , comprising:
 correcting the data in accordance with environmental condition.   
     
     
         10 . The operation control method according to  claim 9 , wherein the environmental condition includes weather. 
     
     
         11 . The operation control method according to  claim 1 , comprising:
 obtaining data concerning a drive of the first construction machine at a first yard, wherein   the data is applied at a second yard that is different from the first yard.   
     
     
         12 . The operation control method according to  claim 1 , wherein
 the excavation of the first construction machine starts in accordance with end of excavation of the last construction machine.
