Abstract
There are included an eco guidance determination unit that detects the occurrence of fuel-wasting operation during operation of a construction machine, and a guidance display control unit that stores guidance for energy saving corresponding to energy wasting operation; that, when fuel-wasting operation occurs, displays corresponding guidance for energy saving; and that also displays the corresponding guidance for energy saving at a predetermined timing after occurrence of the energy wasting operation.
Claims12
A guidance output method that outputs guidance for energy saving for a construction machine on which a guidance output device is mounted, the guidance output device receives outputs from a control system of the construction machine, comprising:
- a guidance storage step of storing, by a guidance storage unit of the guidance output device, guidances for energy saving corresponding to a plurality of categories of energy wasting operations with priorities of said guidances;
- a detection step of, during the operation of said construction machine on which said guidance output device is mounted, detecting by the guidance output device the occurrence of energy wasting operation;
- a determining step of, by the guidance output device, determining whether the energy wasting operation has continued for at least a predetermined time interval;
- an output control step of, by the guidance output device, along with outputting corresponding guidance for energy saving when said energy wasting operation has been detected, also outputting said corresponding guidance for energy saving at a predetermined timing after the occurrence of said energy wasting operation, when it is determined that the energy wasting operation continues for at least the predetermined time interval, and wait to output said corresponding guidance until after the energy wasting operation continues for at least the predetermined time interval;
- and
- a priority guidance step that determines, by the guidance output device, whether two or more categories of said energy wasting operations are detected;
- and
- when the priority guidance determination unit determines that two or more categories of said energy wasting operations are detected:
- determine which two or more guidance for energy saving, from among the guidances for energy saving which are stored in said guidance storage unit, correspond to the two or more categories of said energy wasting operations which are detected;
- and
- determine which among the two or more guidance for energy saving, which are determined to correspond to the two or more categories of said energy wasting operations that are detected, has a most priority so as to be preferentially outputted among the two or more guidances when the two or more categories of said energy wasting operations have a same number of occurrences, wherein a guidance for energy saving for a category of energy wasting operation that has occurred the most times is outputted as a priority when the two or more categories of said energy wasting operations have a different number of occurrences;
- wherein said output control step outputs, by the guidance output device, said guidance for energy saving that has been determined to be outputted as the priority, at said predetermined timing.
