[Problems to be solved by the invention]
By the way, it is hard to say that the above-described conventional technology always realizes accurate performance measurement.
[0008]
In the conventional case, for example, when measurement data is obtained, it is compared with the reference data indicated in the specifications of the construction machine. Based on the comparison result, the presence or absence of an abnormality or the deterioration of performance (aging) ) Is usually judged. However, the reference data shown in the specifications is a value calculated on the desk based on the performance of each component at the design stage, and is measured before authentic shipment related to the construction machine being judged. The performance data thus obtained, that is, the data at the time of shipment does not necessarily match.
[0009]
For this reason, there is a concern that a place where a measurement target apparatus or device should be determined to be abnormal may be determined to be normal, or that a position that should be determined to be normal may be determined to be abnormal. . If it is determined that something that should be abnormal is normal, the apparatus, equipment, or the like may break down during work, leading to a significant reduction in work efficiency. Also, if it is determined that what should be normal is abnormal, the device, equipment, etc. may be replaced, resulting in an unnecessary economic shortening of the original life, which may be uneconomical.
[0010]
The present invention has been made from the actual situation in the above-described prior art, and its purpose is information management of construction machines that can realize with high accuracy whether or not there is an abnormality in an apparatus, equipment, etc. at the time of inspection carried out after actual operation.

[0039]
For the hydraulic excavator shown in FIG. 1, before shipment, as shown in FIG. 3 (a), in addition to the rated engine speed at shipment, pump pressure during relief, etc. Various performance data such as operating speed test data such as time and arm dump time at the time of shipment are measured, and these performance data are stored in advance as shipment time data in the second storage unit 20 of the storage unit 18 shown in FIG. Processing is performed.
[0040]
Suppose now that operation speed test data, for example, an arm cloud time, which is the time required for the arm to rotate downward a predetermined distance in the vertical direction, is selected as measurement data.
[0041]
In consideration of measuring the arm cloud time as described above during the maintenance and inspection of the hydraulic excavator shown in FIG. 1 that has been operated for a certain period of time, first, as shown in step S1 of FIG. The operation of connecting the terminal device 23 to the connection unit 21 is performed.
[0042]
When the power of the terminal device 23 connected in this way is turned on and a predetermined initial operation is performed, measurement is performed from the CPU 16 of the controller 14 to the terminal device 23 via the terminal device connection unit 21 as shown in step S30 of FIG. A preparation screen display command is output. In response to this display command, for example, a measurement preparation screen shown in FIG. 7 is displayed on the display unit 24 of the terminal device 23 as shown in step S11 of FIG.
[0043]
Next, the operator selects a semi-automatic mode, that is, a semi-automatic measurement mode from the display screen shown in FIG. 7 as shown in step S2 of FIG. 4, and further, as shown in step S3 of FIG. That is, in this case, the arm cloud time is selected, and “Next” on the screen shown in FIG. 7 is operated.
[0044]
As a result, as shown in step S31 of FIG. 6, a posture preparation screen display command is output from the CPU 16 of the controller 14 to the terminal device 23 via the terminal device connection unit 21, and as shown in step S32 of FIG. The CPU 16 outputs a setting start angle S that is an upper limit threshold value and a setting end angle E that is a lower limit threshold value to the terminal device 23 via the terminal device connection unit 21.
[0045]
In response to the posture preparation screen display command at that time, for example, the posture preparation screen shown in FIG. 8 is displayed on the display unit 24 of the terminal device 23 as shown in step S12 of FIG. Further, as shown in step S13 of FIG. 5, the setting start angle S and the setting end angle E are input to the terminal device 23 and stored.
[0046]
Next, the operator performs operations related to the bucket cylinder 9, the arm cylinder 8, and the boom cylinder 7 according to the instructions on the posture preparation screen shown in FIG. 8 that displays the arm cloud time measurement method included in the program of the controller 14. Each of the levers is operated to perform a posture preparation operation on the arm 5 as shown in step S4 of FIG.
[0047]
That is, first, the bucket 6 is operated so that the tip of the bucket 6 is positioned on the straight line of the arm 5. Next, in this state, the boom 4 is operated so that the tip of the bucket 6 is 500 mm from the ground. Next, the arm 5 is operated to the maximum dump in that state. That is, the arm 5 is rotated upward to the maximum. The arm angle at this time, for example, the angle of the arm 5 with respect to the boom 4 is detected by an arm angle sensor (not shown), is input to the CPU 16 via the state signal input unit 15 shown in FIG. 2, and is further input from the CPU 16 via the terminal device connection unit 21. Are output to the terminal device 23 and stored in the terminal device 23.
[0048]
Next, the operator commands the start of measurement as shown in step S5 of FIG. That is, the “measurement start” on the screen shown in FIG. 8 is operated. As a result, as shown in step S14 of FIG. 5, for example, a measurement start command screen shown in FIG. At this time, the terminal device 23 determines whether or not the arm angle is equal to or larger than the setting start angle S that is an upper limit threshold, as shown in step S15 of FIG. If this determination is not satisfied, the following processing is not executed.
[0049]
In a state where the determination in step S15 of FIG. 5 is satisfied, as shown in step S6 of FIG. 4, the operator operates the operation lever related to the arm cylinder 8 to perform the arm cloud sudden operation displayed in FIG. When done, automatic measurement of arm cloud time is started. That is, when an operation signal related to the operation lever for operating the arm cylinder 8 is input to the CPU 16 via the state signal input unit 15 of the controller 14, the CPU 16 sets the time of the internal clock 17 as shown in step S33 of FIG. Is output to the terminal device. The time at this time is memorize | stored in the terminal device 23 as start time, as shown to procedure S16 of FIG.
[0050]
During this arm cloud sudden operation, an arm angle is input from the arm angle sensor (not shown) to the CPU 16 via the state signal input unit 15 of the controller 14, and this arm angle is further output to the terminal device 23. In the terminal device 23, as shown in step S17 of FIG. 5, it is determined whether or not the arm angle is equal to or smaller than a setting end angle E that is a lower limit threshold value.
[0051]
When the determination in step S17 is satisfied, that is, when it is considered that the arm cloud operation has been completed, as shown in step S34 in FIG. The time of the clock 17 is output to the terminal device 23. The time at this time is stored in the terminal device 23 as the end time as shown in step S18 of FIG.
[0052]
Next, as shown in step S19 of FIG. 5, the terminal device 23 performs a measurement completion notification process, for example, a process of outputting a notification sound.
[0053]
As shown in step S7 of FIG. 4, the operator who has confirmed this notification sound ends the lever operation of the arm cloud as shown in step S8 of FIG.
[0054]
On the other hand, after the notification sound output processing in step S19 in FIG. 5, the terminal device 23, as shown in step S20 in FIG. 5, uses the arm cloud time T ( n) An operation for obtaining T (1) as follows is performed.
[0055]
T (1) = end time−start time
Next, as shown in step S21 of FIG. 5, the number of measurements n is counted. Now, it is counted as one measurement.
[0056]
Next, as shown in step S22 of FIG. 5, the terminal device 23 determines whether or not the number of measurements n is three. If this determination is not satisfied, measurement continuation processing is performed as shown in step S23 of FIG. 5, and the process proceeds to step S14 of FIG. 5 to perform measurement start instruction screen display processing. That is, the measurement start command screen shown in FIG.
[0057]
Therefore, the worker performs the arm cloud sudden operation similar to the above, for example, two more times.
[0058]
When the determination in step S22 of FIG. 5 is satisfied, as shown in step S24 of FIG. 5, the display unit 24 of the terminal device 23 displays three measurement completions, and as shown in step S25 of FIG. In the terminal device 23, the following calculation for obtaining the measurement data T, which is the average value of the data related to the arm cloud time, is performed.
[0059]
T = {T (1) + T (2) + T (3)} / 3
Next, as shown in step S <b> 26 of FIG. 5, the measurement data T obtained by the above calculation is displayed on the display unit 24 of the terminal device 23. FIG. 10 shows a display screen on the display unit 24 of the terminal device 23 at this time.
[0060]
Here, as shown in step S9 in FIG. 4, when the operator wants to confirm the comparison between the obtained measurement data T and the shipping data, “Comparison” on the screen in FIG. 10 is operated.
[0061]
As a result, the terminal device 23 performs a result comparison display process as shown in step S27 of FIG. At this time, a shipping data request signal is output from the terminal device 23 to the CPU 16 via the terminal device connection unit 21 of the controller 14. In response to this, the CPU 16 outputs the shipping time data related to the corresponding arm cloud time stored in the second storage unit 20 of the storage unit 18 to the terminal device 23 via the terminal device connection unit 21. As a result, the terminal device 23 performs a result comparison display process as shown in step S27 of FIG. 5, and a measurement result comparison display screen is displayed on the display unit 24 of the terminal device 23 as shown in FIG. The
[0062]
For example, based on the measurement data T related to the arm cloud time displayed on the comparison display screen shown in FIG. 11 and the shipping data, the obtained measurement data, that is, the arm cylinder 8 related to the arm cloud time is included. It is determined whether or not an abnormality has occurred in the operation system apparatus or device.
[0063]
When the operator confirms the comparison result and operates “end” on the screen shown in FIG. 11, the screen is returned to the above-described screen in FIG. 10. Here, when the operator operates “registration” on the screen of FIG. 10 as shown in step S10 of FIG. 4, measurement data is registered in the terminal device 23 as shown in step S28 of FIG. . That is, the measurement data T related to the arm cloud time obtained by the current measurement is input from the terminal device 23 to the CPU 16 via the terminal device connection unit 21, and stored in the controller 14 as shown in step S35 of FIG. Measurement data T relating to the obtained arm cloud time is stored in the first storage unit 19 of the unit 18. Thereby, the work and operation by the operator related to the measurement of the arm cloud time, and the processing operations in the series of terminal devices 23 and the controller 14 are completed.
[0064]
For example, when the operator operates “end” on the screen of FIG. 10, the measurement preparation screen shown in FIG. 7 is returned. Therefore, if necessary, the next measurement for obtaining operating speed test data such as the arm dump time, boom raising time, boom lowering time, etc., or the engine speed, the relief pressure of the cylinders 7-9, the pump pressure at the time of relief, etc. The following measurements are performed to determine the performance data:
[0065]
In addition, for example, transient response data such as the rise time from when the operating lever is operated until the corresponding hydraulic actuator is driven, or the pilot pressure when a predetermined time is reached after the operating lever is Adopted as data and measurement data, the second storage unit 20, the first Memory You may make it memorize | store in the applicable thing of the part 19 previously.
[0066]
[Manual measurement mode]

[0067]
12 is a flowchart showing an operator's work procedure, FIG. 13 is a flowchart showing an operation procedure in the terminal device, and FIG. 14 is a flowchart showing an operation procedure in the controller.
[0068]
Note that, for example, the current measurement is also selected with the arm cloud time as the target, as described above.
[0069]
First, as shown in step S40 of FIG. 12, the operator performs an operation of connecting the terminal device 23 to the terminal device connection unit 21 of the controller 14.
[0070]
As a result, a measurement preparation screen display command is output from the CPU 16 of the controller 14 to the terminal device 23 via the terminal device connection unit 21 as shown in step S70 of FIG. In response to this display command, the measurement preparation screen shown in FIG. 7 is displayed on the display unit 24 of the terminal device 23 as described above, as shown in step S60 of FIG.
[0071]
Next, the operator selects the manual measurement mode from the display screen shown in FIG. 7 as shown in step S41 of FIG. 12, and further, as shown in step S42 of FIG. In this case, the arm cloud time is selected, and “Next” on the screen shown in FIG. 7 is operated.
[0072]
As a result, as shown in step S71 of FIG. 14, a posture preparation screen display command is output from the CPU 16 of the controller 14 to the terminal device 23 via the terminal device connection unit 21, and the terminal device is displayed as shown in step S61 of FIG. 23, the posture preparation screen display process is performed, and the posture preparation screen shown in FIG. 8 is displayed on the display unit 24 of the terminal device 23, for example.
[0073]
Next, the operator operates the operation levers related to the bucket cylinder 9, the arm cylinder 8 and the boom cylinder 7 in accordance with the instructions on the posture preparation screen shown in FIG. As shown in step S43, the posture preparation operation for the arm 5 is performed.
[0074]
That is, as described above, the bucket 6 is operated so that the tip of the bucket 6 is positioned on the straight line of the arm 5. Next, in this state, the boom 4 is operated so that the tip of the bucket 6 is 500 mm from the ground. Next, the arm 5 is operated to the maximum dump in that state. That is, the arm 5 is rotated upward to the maximum.
[0075]
Next, for example, the operator commands the start of measurement as shown in step S44 of FIG. That is, “Measurement start” in FIG. 8 is operated. Thereby, as shown in step S62 of FIG. 13, the terminal device 23 is instructed to start measurement, and displays, for example, a measurement start screen shown in FIG.
[0076]
In accordance with the instructions on the screen shown in FIG. 9, as shown in step S45 of FIG. 12, the operator operates the operation lever related to the arm cylinder 8 to perform the arm cloud sudden operation, and at the same time, holds the stopwatch at hand. Operate to start measurement.
[0077]
Next, as shown in step S46 of FIG. 12, at the end of the arm cloud sudden operation, the stopwatch at hand is operated to end the measurement, and as shown in step S47 of FIG. End the operation of the control lever.
[0078]
Next, the operator reads the measurement data that is the time measured by the stopwatch, that is, the time required for the arm cloud, as shown in step S48 of FIG. 12, and the terminal device as shown in step S49 of FIG. The measurement data is input to 23.
[0079]
Here, as shown in step S63 of FIG. 13, the terminal device 23 inputs the inputted measurement data and stores it as the first measurement data T (1).
[0080]
After that, the operator repeats the operations in steps S45 to S49 in FIG. 12 twice, for example, to measure the arm cloud time accompanying the arm cloud sudden operation similar to the above. The terminal device 23 receives and stores the second measurement data T (2) and the third measurement data T (3).
[0081]
As described above, when the measurement is completed three times, the operator operates the terminal device 23, and based on the obtained measurement data T (1), T (2), and T (3), FIG. As shown in step S64 of FIG. 13, the terminal device 23 performs the following calculation to obtain the average value of the data, that is, the measurement data T related to the current manual measurement.
[0082]
T = {T (1) + T (2) + T (3)} / 3
The result of this calculation is displayed on the display unit 24 of the terminal device 23 in a state where, for example, the “semi-automatic mode” on the screen of FIG. .
[0083]
Here, as shown in step S50 of FIG. 12, when the operator wants to perform comparison confirmation between the obtained measurement data T and the shipping data, “Comparison” on the screen of FIG. 10 is operated.
[0084]
As a result, the terminal device 23 performs a result comparison display process as shown in step S66 of FIG. At this time, a shipping data request signal is output from the terminal device 23 to the CPU 16 via the terminal device connection unit 21 of the controller 14. In response to this, the CPU 16 outputs the shipping time data related to the corresponding arm cloud time stored in the second storage unit 20 of the storage unit 18 to the terminal device 23 via the terminal device connection unit 21. As a result, the terminal device 23 performs a result comparison display process as shown in step S66 of FIG. 13, and a measurement result comparison display screen is displayed on the display unit 24 of the terminal device 23 as shown in FIG. The
[0085]
For example, based on the measurement data T related to the arm cloud time displayed on the comparison display screen shown in FIG. 11 and the shipping data, the obtained measurement data T, that is, the arm cylinder 8 related to the arm cloud time is displayed. It is determined whether or not an abnormality has occurred in the operation system devices and equipment.
[0086]
When the operator confirms the comparison result and operates “end” on the screen shown in FIG. 11, the screen is returned to the above-described screen in FIG. 10. Here, when the operator operates “registration” on the screen of FIG. 10 as shown in step S51 of FIG. 12, measurement data is registered in the terminal device 23 as shown in step S67 of FIG. . That is, the measurement data T related to the arm cloud time obtained by the current measurement is input from the terminal device 23 to the CPU 16 via the terminal device connection unit 21, and stored in the controller 14 as shown in step S72 of FIG.

[0099]
Then, when the “end” of the screen on which the shipping data and the measurement data T are displayed is operated, for example, the measurement preparation screen shown in FIG. 7 is returned.
[0100]
In the present embodiment, for example, a terminal device 23 composed of a portable personal computer is used. Instead of the terminal device 23, for example, a monitor display 13 is used as shown in FIGS. An operation panel 13a may be provided, and a series of processes may be performed by operating the operation panel 13a.
[0101]
As described above, according to the present embodiment, the storage unit 18 of the controller 14 includes the second storage unit 20 that stores the shipping time data that is performance data before shipment related to the hydraulic excavator, and therefore, the measurement result includes In the determination based on the measurement data T, the obtained measurement data T may be compared with the corresponding shipping data stored in the second storage unit 20. The shipment data at this time is different from the reference data shown in the specification, and is performance data measured before the genuine shipment related to the hydraulic excavator. Therefore, the obtained measurement data T is shown in the specification. Compared with the case of comparing with the reference data, less error is required. As a result, it is possible to determine with high accuracy whether or not an abnormality has occurred in the corresponding device or device during inspection of the device or device, and to accurately grasp the time for replacement of the device or device subject to inspection. It is possible to prevent the efficiency from decreasing and to prevent unnecessary shortening of the service life of devices, equipment, etc., which have been inspected, thereby improving the economy.
