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.

Claims

1. A guidance output device that outputs guidance for energy saving for a construction machine, comprising:

a guidance storage means that stores guidance for energy saving corresponding to energy wasting operation;

an occurrence detection means that, during the operation of said construction machine, detects the occurrence of energy wasting operation; and

an output control means that, along with outputting corresponding guidance for energy saving when said energy wasting operation has been detected, also outputs said corresponding guidance for energy saving at a predetermined timing after the occurrence of said energy wasting operation.

2. A guidance output device according to claim 1, wherein:

said guidance storage means stores guidances for energy saving corresponding to a plurality of types of energy wasting operation;

there is further included a priority guidance determination means that, from among guidances for energy saving corresponding to one or more types of said energy wasting operation the occurrence of which has been detected by said occurrence detection means, determines a guidance for energy saving that is to be outputted as a priority; and

said output control means outputs said guidance for energy saving that has been determined to be outputted as a priority, at said predetermined timing.

3. A guidance output device according to claim 2, further comprising a measurement means that measures the number of times, or the frequency, that each of said types of energy wasting operation has occurred;

and wherein said priority guidance determination means determines the guidance for energy saving that is to be outputted as a priority, on the basis of the number of times, or the frequency, at which each of said types of energy wasting operation has occurred.

4. A guidance output device according to claim 3, wherein said measurement means measures the number of times from a predetermined time instant, or the number of times from the turning on of a key that is actuation to turn on the power supply of said construction machine.

5. A guidance output device according to claim 3, further comprising:

a transmission means that transmits the number of times, or the frequency, that the type of energy wasting operation corresponding to each of said conditions has occurred to a management center device; and

a reception means that receives from said management center device average occurrence information related to the average number of occurrences, or the average frequency of occurrence, of energy wasting operation of construction machines of the same type;

and wherein said priority guidance determination means determines said guidance to be outputted as a priority, on the basis of said average occurrence information that has been received, and the number of times, or the frequency, of occurrence of each of said types of energy wasting operation.

6. A guidance output device according to claim 4, wherein said output control means compares together said average occurrence information that has been received and the number of times, or the frequency, that each of said types of energy wasting operation has occurred, and outputs a display or audio that specifies the result of this comparison.

7. A guidance output device according to claim 1, further comprising an operation detection means that detects ending of working and/or starting of working of said construction machine;

and wherein said output control means outputs said guidance for energy saving upon detection of said ending of working and/or of said starting of working.

8. A guidance output device according to claim 1, further comprising:

a guidance storage means that stores, for each operator, operator identification information and guidance for energy saving corresponding to each of said types of energy wasting operation that have been detected during operation by said operator, in mutual correspondence; and

an identification information acquisition means that acquires identification information of the operator who performs turning on of a key;

and wherein said output control means outputs said guidance for energy saving corresponding to said identification information that has been acquired.

9. A guidance output device according to claim 1, wherein, when fault information for said construction machine is outputted, said output control means does not output said corresponding guidance for energy saving, even if said energy wasting operation has occurred.

10. A guidance output device according to claim 1, wherein, if said energy wasting operation has not occurred even once, said output control means outputs a message specifying that operation is good.

11. A guidance output method that outputs guidance for energy saving for a construction machine, comprising:

a guidance storage step of storing guidance for energy saving corresponding to energy wasting operation;

a detection step of, during the operation of said construction machine, detecting the occurrence of energy wasting operation; and

an output control step of, 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.
