Abstract

A display device for displaying information toward outside of a work machine is installed in the work machine.

Claims

1. A display device for construction machine, which is arranged in a construction machine and comprises:

a memory device that stores operator data, the operator data being suitable for operators of the construction machine and including a work process chart that sets forth scheduled works to be done and work performance results in a construction site;

a data retrieving device that retrieves the operator data stored in the memory device;

a data processing device that processes the operator data retrieved by the data retrieving device into simplified data, the simplified data being the operator data that is changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of the construction machine, the data display screen displaying the simplified data so that the simplified data is readable from the outside of the construction machine.

7. The display device for construction machine as set forth in claim 1, wherein:

an operator display device for use by an operator is provided in an operator room of the construction machine; and

the operator display device displays the operator data which is retrieved from the memory device by the data retrieving device and which is not processed by the data processing device.

2. A display device for construction machine, which is arranged in a construction machine and comprises:

a measuring instrument for measuring noise levels;

a memory device that stores noise data on the noise levels in a construction site measured by the measuring instrument;

a data retrieving device that retrieves the noise data stored in the memory device;

a data processing device that processes the noise data into processed data, the processed data being the noise data that is changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of the construction machine, the data display screen displaying the process data that was processed from the noise data so that the processed data is readable from the outside of the construction machine.

3. A display device for construction machine, which is arranged in a construction machine and comprises:

a measuring instrument for measuring toxic substance concentrations in a construction site;

a memory device that stores toxicity data on the toxic substance concentrations in the construction site;

a data retrieving device that retrieves the toxicity data stored in the memory device;

a data processing device that processes the toxicity data retrieved by the data retrieving device into processed data, the processed data being the toxicity data that is changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of the construction machine, and the display device displaying the processed data that was processed from the toxicity data by the data processing device so that the processed data is readable from the outside of the construction machine.

4. A display system for construction machines adapted for a construction site where a plurality of construction machines are in operation, the plurality of construction machines being connected through a communication apparatus so as to enable transmission and reception of data among the construction machines, which includes:

one of the plurality of construction machine is designated as a leader machine, and remaining construction machines are designated as follower machines;

operator data is transmitted from the leader machine to the follower machines via the communication apparatus, the operator data being suitable for operators of the construction machine and including a work process chart that sets forth scheduled works to be done and work performance results in a construction site data; and

at least one of the construction machines is provided with;

a data processing device that processes the operator data into simplified data, the simplified data being the operator data that is changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of said at least one of the construction machines, the data display screen displaying the simplified data so that the simplified data is readable from the outside of the construction machine.

8. The display device for construction machine as set forth claim 4, wherein:

an operator display device for use by an operator is provided in an operator room of the construction machine; and

the operator display device displays the operator data which is retrieved from the memory device by the data retrieving device and which is not processed by the data processing device.

5. A display system for construction machines adapted for a construction site where a plurality of construction machines are in operation, the plurality of construction machines being connected through a communication apparatus so as to enable transmission and reception of data among the constructions machines, which includes:

a measuring instrument for measuring noise levels in the construction site is provided on one or plural construction machines, and the measuring instrument on the one or plural construction machines measuring noise levels in the construction site;

one of the one or plural construction machines having measured noise levels transmitting the measured noise levels to other of the plurality of construction machines via the communication apparatus; and

at least one of the plurality of construction machines is provided with;

a data processing device that processes the measured noise levels into processed data, the processed data being the measured noise levels that are changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of said at least one of the construction machines, the data display screen displaying the processed data that was processed from the measured noise levels so that the processed data is readable from the outside of said at least one of the construction machines.

6. A display system for construction machines adapted for a construction site where a plurality of construction machines are in operation, the plurality of construction machines being connected through a communication apparatus so as to enable transmission and reception of data among the constructions machines, including:

a measuring instrument for measuring toxic substance concentrations in the construction site is provided on one or plural construction machines, and the measuring instrument on the one or plural construction machines measuring toxic substance concentrations in the construction site;

one of the one or plural construction machines having measured toxic substance concentrations transmitting the measured toxic substance concentrations to other of the plurality of construction machines via the communication apparatus; and

at least one of the plurality of construction machines is provided with;

a data processing device that processes the measured toxic substance concentrations into processed data, the processed data being the measured toxic substance concentrations that are changed and made suitable for people in the neighborhood of the construction site; and

a data display screen that is arranged to face toward an outside of said at least one of the construction machines, the data display screen displaying the processed data that was processed the measured toxic substance concentrations into the processed data so that the processed data is readable from the outside of said at least one of the construction machines.
