Abstract

A loading work assistance system includes a loading-progress-degree calculation unit that calculates a degree of progress of loading work performed on a transport vehicle located in a construction site by a loading vehicle, a determination unit that determines whether or not the degree of progress is equal to or more than a degree-of-progress determination threshold value, and a transport vehicle starting instruction unit that instructs the transport vehicle standing by to be started in a case where the degree of progress is equal to or more than the degree-of-progress determination threshold value.

First claim

1 . A loading work assistance system which gives an instruction to a transport vehicle standing by on the basis of information regarding loading work performed on a transport vehicle located in a construction site by a loading vehicle, the loading work assistance system comprising:
a loading-progress-degree calculation unit that calculates a degree of progress of the loading work performed on the transport vehicle located in the construction site by the loading vehicle; a determination unit that determines whether or not the degree of progress is equal to or more than a degree-of-progress determination threshold value; and a transport vehicle starting instruction unit that instructs the transport vehicle standing by to be started in a case where the degree of progress is equal to or more than the degree-of-progress determination threshold value.

2 . The loading work assistance system according to claim 1 , further comprising:
a transport vehicle information acquisition unit that acquires a maximum load capacity of each of the transport vehicles, wherein the loading-progress-degree calculation unit calculates the degree of progress on the basis of the maximum load capacity.

3 . The loading work assistance system according to claim 2 ,
wherein the transport vehicle information acquisition unit further acquires an original load amount of the transport vehicle, and wherein the loading-progress-degree calculation unit calculates the degree of progress on the basis of the maximum load capacity and the original load amount.

4 . The loading work assistance system according to claim 1 , further comprising:
a load calculation unit that calculates a load of a transport object which is loadable onto the transport vehicle through one loading operation, wherein the loading-progress-degree calculation unit calculates the degree of progress on the basis of an accumulated value of the load calculated every loading operation.

5 . An information provision method of giving an instruction to a transport vehicle standing by on the basis of information regarding loading work performed on a transport vehicle located in a construction site by a loading vehicle, the information provision method comprising the steps of:
determining whether or not the loading vehicle is in a loading state with respect to a transport vehicle which is a loading work target; calculating a degree of progress of the loading work performed on the transport vehicle which is a loading work target by the loading vehicle in a case where the loading vehicle is in the loading state; determining whether or not the degree of progress is equal to or more than a degree-of-progress determination threshold value; and instructing the transport vehicle standing by to be started in a case where the degree of progress is equal to or more than the degree-of-progress determination threshold value.

6 . An information provision method of giving an instruction to a transport vehicle standing by on the basis of information regarding loading work performed on a transport vehicle located in a construction site by a loading vehicle, the information provision method comprising the steps of:
receiving designation of a transport vehicle which is a loading work target; determining whether or not the loading vehicle is in a loading state with respect to the designated transport vehicle in a case where the designation of the transport vehicle is received; calculating a degree of progress of loading work performed on the designated transport vehicle by the loading vehicle in a case where the loading vehicle is in the loading state; determining whether or not the degree of progress is equal to or more than a degree-of-progress determination threshold value; and instructing the transport vehicle standing by to be started in a case where the degree of progress is equal to or more than the degree-of-progress determination threshold value.

7 . The loading work assistance system according to claim 2 , further comprising:
a load calculation unit that calculates a load of a transport object which is loadable onto the transport vehicle through one loading operation, wherein the loading-progress-degree calculation unit calculates the degree of progress on the basis of an accumulated value of the load calculated every loading operation.

8 . The loading work assistance system according to claim 3 , further comprising:
a load calculation unit that calculates a load of a transport object which is loadable onto the transport vehicle through one loading operation, wherein the loading-progress-degree calculation unit calculates the degree of progress on the basis of an accumulated value of the load calculated every loading operation.
