Normally, the number of times of excavation and the excavation time required for excavation in each excavation area have values expected from the average of past measured values and the amount of work, and the computer 30 stores these set values. .

In step 50, the measured number of excavations N (i, j) in each excavation area A (i, j) is converted into a reference level value Nlv created based on the above set values. The level-converted excavation frequency Nlv (i, j) in each excavation area A (i, j) is obtained. In this level conversion, as shown in step 50, the number of excavations N (i, j)
With a focus on 0.0 corresponding to the planned number of excavations No.
The conversion is performed using a reference level value Nlv consisting of +1.0 corresponding to the upper limit value Nmax of the planned excavation number and −1.0 corresponding to the lower limit value Nmin of the planned excavation number. Here, N
max and Nmin are respectively 20 of the planned number of excavations No.
Although the values are set to increase by 20% and decrease by 20%, these values can be arbitrarily set so that the operator can easily confirm the visual check. .

Next, in step 51, step 5
0, the level-converted number of excavations Nlv (i,
j) is converted into the number of excavations Nlv (i, i,
Steps are classified according to the color corresponding to the value of j) or its shade. Here, as shown in step 51, the level-converted number of excavations Nlv (i, j) = + 1.0 to -1.0 is colored in several stages from red to blue according to the value. The color coding is performed so that the operator can understand the difference. Here, if the level-converted excavation frequency Nlv (i, j) is larger than the planned frequency No (= 0.0), the excavation frequency Nlv (i, j) is classified into red, if less, the color is classified into blue, and the color is further divided into shades. To That is, the level-converted number of excavations Nlv
(I, j) is colorless from -0.1 to +0.1, 0.1 to
The whole is divided into 11 levels by a color scheme such as light red up to 0.3.

In step 52, each excavation area A (i,
j), the colors of the level-converted digging times Nlv (i, j) for each digging area A (i, j) and the display image data subjected to the shading processing are performed by performing the processing of steps 50 to 51. Get.

FIG. 13 is an example of a display image on the display device 32 obtained by the above display processing.

Reference numeral 40 denotes each of the lattice-shaped excavation areas A (i, j).
Number Nlv (i, j) of level-converted excavations corresponding to
Is a display screen displayed in different colors, and the area (i,
The colorless color in j) indicates that the number of excavations is almost as planned, and is displayed such that the reddish color (shading in the figure) is more than the planned number of excavations at a glance.

Reference numeral 41 denotes the number of excavations Nlv whose level has been converted.
And the relationship between the colors and the colors and their shades.

Reference numeral 42 denotes an average value 421a, a maximum value 421b, and a minimum value 4 of the actual number of excavations measured by the excavator.
21c and the scheduled value 422 set in the processing device 23
a, the maximum value 422b, and the minimum value 422c are displayed. Note that the scheduled value 422a, the maximum value 422b, and the minimum value 42
2c can be set by an operator inputting a numerical value.

In the above description of the display processing, the number of excavations N
Although only (i, j) has been described, the same processing can be performed on other measured values such as the excavation time T (i, j) and the soil volume to obtain a similar display image.

FIG. 14 shows another example of the display image of the display device 32 obtained by performing the display processing of the load measurement data.

In the same manner as in the flow chart shown in FIG. 12, 50 and 51 indicate the level-converted number of digging Nlv (i, j) and the level-converted digging time Tlv (i, j) for each digging area A. The difference in measured value is displayed for each (i, j) as a color and a difference in shade. By displaying both at the same time as described above, the excavation area A (i, j) is compared as a difference in color pattern. For example, the excavation load is similarly reduced around the area where the excavation time is long and the efficiency is low. If a numerical value that is too high is displayed, it is possible to presume that the hardness of the earth and sand due to insufficient blasting is a cause of a decrease in work efficiency.

Next, the computer 30 and the display device 3
1 shows a different example of the load measurement data display process in FIG.
5 will be described.

FIG. 15 relates to the execution of a part of the display program 303c in the computer 30, and displays the received load measurement data 303b as excavation frequency data and excavation time data on the display device 32 as one display image data. It is a flowchart which shows a processing procedure.

At steps 60 and 61, the number of excavations N in each of the measured excavation areas A (i, j) is determined in the same manner as in step 50 of FIG.
From (i, j) the number of excavations Nlv (i, j) converted by the reference level value Nlv, and from the measured excavation time T (i, j) in each excavation area A (i, j), the reference level value Tlv. Time Tlv converted by
(I, j) is obtained.

Next, in step 62, the level is converted to the number of excavations Nlv (i, j) and the excavation time Tlv.
To determine the correlation with (i, j), each excavation area A
The difference NTlv (i, j) between the two for each (i, j) is determined by the following equation.

NTlv (i, j) = ｛Nlv (i, j)
−Tlv (i, j)｝ / 2 The reason for dividing by 2 in the above equation is to change the value range of NTlv (i, j) from −1.0 to +1.0.

Next, step 63 and step 64
Then, the same processing as the processing in step 51 and step 52 of FIG. 12 is executed, and each excavation area A (i, j)
The correlation data N of the number of excavations and the excavation time
The color of Tlv (i, j) and the display image data subjected to the shading process are obtained.

As described above, by correlating and displaying the number of excavations N (i, j) and the excavation time T (i, j), the number of excavations N (i, j) and the excavation time T (i, j) are displayed. When j) indicates the same level, the color of the corresponding image becomes lighter and the color becomes darker as the level increases, so that the positions of the number of excavations N (i, j) and the excavation time T (i, j) Each association becomes easy to compare.

As described above, when there are many types of measured values or when there are many area divisions, the correlation between the measured values is displayed to facilitate the visual judgment processing.
