Abstract

A construction management device computes a risk indicative of a degree of danger with which an accident occurs on the basis of information relating at least to a position of a worker measured by a worker position measuring device and a worker biometrical information measuring device, information relating at least to a position of a hydraulic excavator measured by a machine body position measuring device, a machine body posture measuring device, a machine front implement posture measuring device, and a machine operator biometrical information measuring device, personal information on a worker and an operator registered in a worker information registration device, and information on a construction environment from an environment information registration device, and outputs the computed risk as a coordinate risk associated with coordinates of the construction environment to a risk display device such that the computed risk is displayed in a map format on the risk display device.

First claim

The invention claimed is:

1. A construction management system, comprising:
a worker measuring device for measuring information relating at least to a position of a worker as a state of the worker;
and
a construction management device that is configured to compute, on the basis of information relating at least to a position of the worker measured by the worker measuring device, information relating at least to a position of the work machine measured by the machine measuring device, personal information on the worker and an operator who operates the work machine, and information on the construction environment a risk that indicates a degree of danger with which an accident occurs, and output the computed risk as a coordinate risk associated with a coordinate of the construction environment to a risk display device such that the risk is displayed in a map format on the risk display device.

2. The construction management system according to claim 1 , wherein
the construction management device is configured to compute, on a basis of the information on the worker that is a side suffering the risk, an internal risk arising from a state of the side that suffers the risk, compute, on a basis of the information on the work machine that is a side providing the risk and on the operator, an external risk arising from a state of the side that provides the risk, and integrate the internal risk, the external risk, and geometrical information on the worker and the work machine to compute the coordinate risk.

3. The construction management system according to claim 1 , wherein
the construction management device is configured to compute, in case that a plurality of workers exist, on a basis of information on each of a plurality of workers, personal information on each of the plurality of workers, personal information on the operator, and information on the construction environment, a coordinate risk in regard to each of the plurality of workers, and output a result where a plurality of the coordinate risks associated with a same coordinate are synthesized so as to take a maximum value of the coordinate risks to the risk display device such that the result is displayed in a map format on the risk display device.

4. The construction management system according to claim 1 , wherein
the construction management device is configured to compute the coordinate risk so as to be lower at coordinates that are remoter from the position of the worker.

5. The construction management system according to claim 1 , wherein
the construction management device is configured to expand a computation range for the coordinate risk in a direction in which the worker moves.

6. The construction management system according to claim 3 , wherein
the construction management device is configured to synthesize the coordinate risks so as to take a maximum value of the coordinate risks associated with the same coordinate only in regard to a worker selected in advance from among a plurality of the workers, and output a result of the synthesis to the risk display device such that the result of the synthesis is displayed in a map format on the risk display device.

7. The construction management system according to claim 1 , wherein
the worker measuring device includes a worker position measuring device for measuring information relating to the position of the worker and a worker biometric information measuring device for measuring biometric information on the worker, and
the construction management device is configured to compute the risk further on a basis of the biometric information on the worker measured by the worker biometric information measuring device.

8. A work machine, comprising:
a lower track structure;
an upper swing structure swingably provided with respect to the lower track body;
an articulated front work implement attached to the upper swing body and including a plurality of driven members pivotably connected to each other;
a machine measuring device for measuring the upper swing body and the front work implement and a state of the upper swing body; and
a construction management device that is configured to compute, on a basis of information relating at least to a position of a worker measured by a worker measuring device for measuring information relating at least to the position of the worker as a state of the worker, information relating at least to a position of the work machine measured by the machine measuring device, personal information on the worker and an operator who operates the work machine, and information on a construction environment, a risk indicative of a degree of danger with which an accident occurs, and output the computed risk as a coordinate risk associated with a coordinate of the construction environment to a risk display device such that the risk is displayed in a map format on the risk display device.
