Abstract

A construction machine safety management system includes an information generating unit that generates information representing a relationship between a detection result and predetermined related information, based on the detection result obtained by a detecting unit that detects entry of an obstacle into a predetermined area around a construction machine and the predetermined related information corresponding to the detection result.

First claim

What is claimed is:

1. A construction machine safety management system comprising:
a detecting unit that detects entry of an obstacle into a predetermined area around a construction machine; and
an information generating unit that generates an index of information representing a relationship between multiple historical detected entries of obstacles into the predetermined area and multiple pieces of historical entry-related information, wherein
each piece of historical entry-related information of the multiple pieces of historical entry-related information includes one or more entry-related parameters relating to the piece of historical entry-related information,
each piece of historical entry-related information of the multiple historical entry-related information corresponds to a historical detected entry of the multiple historical detected entries, and
the multiple historical detected entries detected by the detecting unit are indexed by a selected entry-related parameter from among the one or more entry-related parameters, and the generated index of information representing a relationship between multiple historical detected entries of obstacles into the predetermined area and multiple pieces of historical entry-related information includes one or more historical detected entries that satisfy a predetermined condition relating to the selected entry related parameter.

2. The construction machine safety management system according to claim 1 , wherein the information generating unit generates the index of the information representing the relationship, based on a predetermined condition relating to the multiple historical detected entries.

3. The construction machine safety management system according to claim 1 , wherein the information generating unit generates the index of the information representing the relationship including at least one of a detection frequency indicating the frequency with which the detecting unit detects the obstacle and a detected count number indicating the number of times the detecting unit detects the obstacle.

4. The construction machine safety management system according to claim 1 , wherein the predetermined condition includes
a condition relating to a time period in which the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a location in which the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to an operation state of the construction machine when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a work mode of the construction machine when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to an alarm level of an alarm that is output when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a distance between the construction machine and the obstacle when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a subsequent action of a person when the entry of the person that is the obstacle into the predetermined area_is detected by the detecting unit,
a condition relating to a work content of the construction machine when the entry of the obstacle into the predetermined area is detected by the detecting unit, or
a condition relating to an operation state of the construction machine when motion limitation of the construction machine is implemented when the entry of the obstacle into the predetermined area is detected by the detecting unit.

5. The construction machine safety management system according to claim 1 , wherein the predetermined condition includes
a condition relating to an elapsed time from alarm start, when the entry of the obstacle into the predetermined area is detected by the detecting unit, to alarm cancellation according to an alarm cancellation operation by an operator,
a condition relating to an elapsed time from motion limitation start of the construction machine, when the entry of the obstacle into the predetermined area is detected by the detecting unit, to motion limitation cancellation according to a motion limitation cancellation operation by an operator,
a condition relating to a setting state of detection performance of the detecting unit when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a surrounding environment when the entry of the obstacle into the predetermined area is detected by the detecting unit,
a condition relating to a stability of an excavator that is, the construction machine when the entry of the obstacle into the predetermined area is detected by the detecting unit, or
a condition relating to an operation skill of an operator within a predetermined period when the entry of the obstacle into the predetermined area is detected by the detecting unit.

6. The construction machine safety management system according to claim 2 , wherein the predetermined condition includes a condition relating to a detection frequency by the detecting unit.

7. The construction machine safety management system according to claim 6 , wherein the condition relating to the detection frequency is a condition that the detection frequency of detecting the obstacle by the detecting unit or a detected count number of the obstacle detected by the detecting unit exceeds a predetermined reference.

8. The construction machine safety management system according to claim 2 , wherein the predetermined condition includes a condition relating to an execution frequency of executing a predetermined response by the construction machine in accordance with the entry into the predetermined area being detected by the detecting unit.

9. The construction machine safety management system according to claim 8 , wherein the condition relating to the execution frequency is a condition that a number of times that a motion of the construction machine is limited, or a number of times that an alarm of a relatively high alarm level is output from the construction machine, caused by the entry into the predetermined area being detected by the detecting unit, exceeds a predetermined reference.

10. The construction machine safety management system according to claim 4 , wherein the information generating unit generates, as the index of the information epresenting the relationship, information relating to a temporal change of a detection frequency of detecting the obstacle by the detecting unit or a detected count number of the obstacle detected by the detecting unit.

11. The construction machine safety management system according to claim 10 , wherein the information generating unit generates, as the information relating to the temporal change, time sequence data per day of a week, per date of a month, or per time period, within a predetermined period.

12. The construction machine safety management system according to claim 1 , further comprising:
a transmitting unit that is provided in the construction machine and that transmits, to a management apparatus outside the construction machine, the multiple historical detection results obtained by the detecting unit and the corresponding multiple historical predetermined related information, wherein
the information generating unit is provided in the management apparatus or in a management terminal that is communicably connected to the management apparatus.

13. The construction machine safety management system according to claim 1 , further comprising:
a displa
