The knowledge about the close relation between the inspection inspection items is often known in advance by the consideration of a skilled engineer or a maker, and by registering the information in the correlation graph item file 22, the experience can be improved. Even a small patrolman can grasp the device status by referring to the correlation graph.

The correlation graph display means 21 determines any one set from the judgment items stored in the correlation graph item file 22, acquires the identification id of the judgment item and the identification id of the corresponding item, Based on the identification id, the past inspection inspection data is first searched from the history data file 16.

Then, the correlation graph display means 21 obtains a regression curve that approximates the retrieved history data group, and displays a linear curve on the graph based on the equation showing the regression curve. Also,
The data groups are displayed on the same graph as a scatter plot.

Next, the inspection result file 15 is read,
Based on the identification id of the determination item and the identification id of the corresponding item, the result of the current inspection inspection data is acquired. The acquired inspection inspection result data is displayed together with the corresponding position on the graph.

FIG. 11 shows an example of the correlation graph display screen 105 by the correlation graph display means 21. As shown in this figure, arbitrary two inspection inspection items that are closely related to each other are arranged on the vertical axis and the horizontal axis, respectively, and the inspection inspection item name 105a and the unit 105b are displayed. In the scatter diagram, as indicated by reference numeral 105c, only the input value obtained by the current inspection inspection is color-changed and displayed. As a result, the deviation between the reference value indicated by the regression curve 105d and the current input value can be confirmed on the same graph.

When there is an item having a close relationship with an arbitrary item set on the vertical axis side, and when it is desired to change the graph display item, the item selection button 105e is displayed on the correlation graph display screen 105 shown in FIG. When is selected, the item selection screen 106 shown in FIG. 12 is displayed, and based on the contents of the correlation graph item file 22, a plurality of corresponding item names 106a registered in advance are shown.

By selecting one of 06b and selecting the graph redisplay button 106c, this screen is erased, and the correlation graph display screen in which the selected item is reset on the horizontal axis side is displayed on the display input unit 12.

Further, in the item selection screen 106 shown in FIG. 12, the list of all inspection item names is displayed by selecting the item list button 106d. Therefore, it is possible to change / add the setting contents from among them by the selection method. it can. The changed / added item information is updated and saved in the correlation graph item file 22 by selecting the save button 106e.

As is clear from the above description, in this embodiment, the regression curve that approximates the history data group and the input value at the time of the present regular inspection are the same for any two items that are correlated with each other. By displaying it on the graph, the relationship between the two items can be visually grasped. Further, it is possible to immediately determine at the site how much the input value at the time of this inspection is different from the reference value indicated by the regression curve, and it is possible to contribute to early detection of an abnormality in the equipment.

In addition, in the above-mentioned embodiment, FIG.
Although the display of the correlation graph display screen 105 as shown in FIG. 10 and the item selection screen 106 as shown in FIG. 12 has been described, the history stored in the history data file 16 as shown in FIG. 13 is not limited to this. It is also possible to realize the screen 107 for displaying a list of data.

On this screen 107, the respective values shown in the scatter diagram of the correlation graph display screen 105 can be known, and the data judged to be abnormal or the abnormal sign by the diagnosis executing means 19 are color-changed or highlighted. By doing so, the patrol officer can be immediately discriminated.

Further, on this screen 107, by making it possible to select the history data used when obtaining the regression curve by the selection button 107a, the regression curve based on the normal value excluding the data with abnormality / abnormal sign The graph of can be displayed and a more accurate reference value can be obtained.

FIG. 14 shows a third embodiment of the portable plant patrol inspection data judging device 11 of the present invention. In comparison with the second embodiment, the abnormality judgment value file 18 is now stored in the abnormal judgment value file 18. A change amount limit value for determining the state of the inspection data by the amount of change from the previous inspection inspection is stored, and the diagnosis execution means 19 stores the inspection result file 15 in which the input value at the current inspection inspection is stored, and Based on the history data file 16 in which the past inspection inspection data is stored, the difference between the instruction values up to the time of the previous inspection inspection is calculated as the change amount, and the change amount and the change amount limit value in the abnormality determination value file 18 are calculated. The previous value change amount determination means 24 for determining the condition of the equipment on the basis of the difference between and is provided as an additional function.

Next, the operation of the portable plant inspection and inspection data determination device 11 having the above configuration will be described by taking maintenance of the components of the hydroelectric power plant as an example.

In the inspection inspection of the plant, the inspection staff brings the portable inspection inspection data determination device 11 to the plant site, and inputs the result of inspection inspection of the plant from the display input unit 12 one after another as described above.

Based on the input plant inspection inspection data, the state is automatically determined by the diagnosis executing means 19 as shown in the above-mentioned embodiment, and the diagnosis executing means 19 further determines the previous value change amount determining means. 24, it is possible to make a detailed diagnosis of the condition of the equipment.

For example, the value of a thermometer attached to each type of equipment does not change drastically between inspections as long as the operating state of the equipment is the same. It is possible to determine the state of the device by comparing and the difference.

Further, for equipment whose status can be ascertained from the number of times of operation and operation time, the measured values of the counters and hour counters attached to measure them are compared with the measured values at the previous inspection inspection. To do. For example, as one of the equipments equipped with a counter and a time meter, there is a device called a strainer that removes foreign matters contained in water, oil, steam, etc., but the operation timing of the equipment depends on the accumulation of foreign matters. It is closely related to the state of other factors such as the decrease in flow rate. Therefore, the state of the strainer itself and the states of other related devices can also be determined by checking the operating state during the inspection inspection.

Based on these things, the diagnosis execution means 19
In order to make a more detailed determination of the inspection inspection data whose state has been determined in step 1, the previous value change amount determination means 2
According to 4, the condition of the equipment is judged based on the difference between the value collected at the previous inspection inspection and the value collected at this inspection inspection.

First, the input value at the time of the previous inspection inspection is acquired from the history data file 16 based on the identification id for any item to be judged, and the abnormality judgment value file 1
The change amount limit value is acquired from 8.

Next, the difference between the acquired input value at the previous inspection and the input value at the current inspection is calculated as the amount of change. In particular, counters and time meters are normalized per day based on the number of days that have passed since the previous inspection inspection date.

For example, if for any counter 1
If it is assumed that the number of times of operation per day has been transferred as shown in FIG. 15 and the upper limit of the change amount limit value is 2, it means that the change amount before the last time-the change amount at the previous time is about 0.5 times. It can be said that it is in the normal range. However, the amount of change from the previous time to the present time is about 2.5 times, which is the upper limit of the change amount limit value of 2
Since it has exceeded the number of times, the previous value change amount determination means 24
It is determined that there is a sign of abnormality in this determination device or the device periphery.

FIG. 16 shows an example of a screen for displaying the judgment result by the diagnosis executing means 19 provided with the previous value change amount judging means 24. Compared with the diagnosis result detail display screen 103 as shown in FIG. Further, the result of the determination based on the previous value change amount is added and displayed. Similar to the screen 103, the diagnosis result detail display screen 108 shows the names and units of the determination items and, unlike the screen 103, displays the input value 108a at the time of the previous inspection. For the judgment of the counter and the hour meter, the value 108b normalized per day is also displayed. Further, the relation between the related data such as the upper and lower limit values used for the previous value change amount determination and the input value by the current inspection is shown in a color-changed display.

As is clear from the above description, in the present embodiment, by giving the above-described variations to the plant equipment diagnosis method, it is possible to grasp the equipment status including the related equipment in many ways. In addition to reducing the burden on patrol personnel by automating the work required to normalize the measurement values obtained by inspecting the counter and time counter that show the number of times the equipment has been operated and the operating status, the inspection work can be performed. Can speed up.

In addition to the comparison with the input value at the previous inspection inspection, by comparing with the arbitrary inspection data such as the value at the inspection in the same month of the previous year, the situation of the target device can be determined more accurately. it can.

FIG. 17 shows a fourth embodiment of the portable plant inspection inspection data judging device 11 of the present invention. In addition to the configuration shown in FIG. 14, two inspection inspections closely related to each other are provided. A function formula information file 26 for storing a function formula that correlatively expresses the relationship between items is provided, the function formula is read from the function formula information file 26, and the inspection result data of any two items are correlated based on the function formula. The diagnosis execution means 19 is provided with a function formula judging means 27 for evaluating the result and displaying the result on the display input unit 12.

Next, the operation of the portable plant patrol inspection data determination device 11 having the above configuration will be described by taking maintenance of the components of the hydroelectric power plant as an example.

For example, for insulating oil that plays a role of electrical insulation and cooling in oil-filled electrical equipment such as transformers, capacitors, cables, etc., an oil level gauge or an oil temperature gauge is used to measure the oil amount and oil temperature. It is installed and its value is checked at the time of patrol inspection. In this case, the amount of insulating oil should always be constant, but the indication state of the oil level gauge must be determined in consideration of the characteristic of oil that the volume expands as the temperature rises.

FIG. 18 shows an example of a graph showing the relationship between the oil level and the oil temperature. This graph is shown by the manufacturer when the equipment is installed. In this graph,
The upper straight line H indicates the upper limit value that is obtained in advance by the relationship between the oil level and the oil temperature, and the lower straight line L indicates the lower limit value.
Therefore, it can be said that the condition of the insulating oil is good when the measured value is included in the portion surrounded by the diagonal line.

The patrol officer determines the state of the insulating oil based on this graph described on the check sheet or the like.

In the present embodiment, since this judgment processing is automatically carried out by the function judgment means 27 on the portable plant inspection inspection data judgment device 11, information concerning two items closely related to each other is provided. It is registered in the function formula information file 26 in advance.

FIG. 19 shows the function formula registration screen 109. The function formula information is set on this screen 109. First, regarding the two inspection items that are closely related to each other,
The inspection inspection device name 109a and the inspection inspection item name 109b are set, respectively.

Next, in order to automatically generate a graph showing the upper limit value, a plurality of required data are set as indicated by reference numerals 109c to 109f. For example, if data on the upper limit side is set based on the relationship example of "oil level indicator-oil temperature" shown in FIG. 18, first, as an appropriate combination data, "2" is set.
0 / -10 "," 40/10 "," 60/30 "," 8 "
0/50 ”is selected and set. Similarly, set the lower limit value side.

When the data is set, the function formula judging means 2
In step 7, a regression curve approximating those values is automatically generated.
The more the set data sets are, the more accurately the regression curve can be obtained. The regression curve is represented by a functional formula of y = ax + b, and the formula is stored in the functional formula information file 26.

Further, on the registration screen 109, an abnormality sign width for grasping an abnormality sign can be set as necessary.

Here, the width between the upper limit value and the lower limit value is 1
00%, and what percentage of that is set as the abnormality symptom width may be designated on the upper limit side and the lower limit side as indicated by reference numerals 109g and 109h, respectively.

After setting various information on the function formula registration screen 109 shown in FIG. 19, a graph display button 109 is displayed.
When i is selected, the function formula is displayed in a graph according to the set information. As a result, it is possible to make adjustments while checking the settings.

FIG. 20 shows a display example of a functional expression graph. In this function formula graph display screen 110, the solid line indicates upper and lower limit values that are boundaries for determining abnormality, and the broken line indicates abnormality sign determination values that indicate boundaries for determining abnormality.

Here, in the case of determining the data on the vertical axis side, if the measured value on the horizontal axis side is a, it is normal if the value on the vertical axis side is within the range 110a in the figure. 110
If it is included in the range of b or 110c, there is an abnormality sign, and if it is included in the range of 110d or 110e, it is determined that there is an abnormality.

In the portable plant inspection inspection data determination device 11 of the present embodiment, after the inspection inspection work is completed, a diagnosis execution means 1 is issued in response to a facility diagnosis execution request from an inspector.
9 indicates, as described above, by comparing the input plant patrol inspection data with the judgment value in the abnormality judgment value file 18,
Automatically determine whether the data value is normal or abnormal. Further, in the case of inspection data such as "oil level indicator indication-oil temperature", which are closely related to each other, the function formula judging means 27 judges the state by the function formula.

For example, when the inspection inspection item is an oil level indicator,
The function-based determination unit 27 first calculates an abnormality determination value and an abnormality symptom determination value for each of the upper limit and the lower limit for determining the state of the oil level indicator indicated value from the value of the measured oil temperature. The determined judgment value is as shown in FIG.

For example, the formula showing the upper limit value is y = x + 30,
Assuming that the equation showing the lower limit value is y = 0.5x + 15, and the abnormality sign width is set to 20% on the upper limit side and 25% on the lower limit side,
If the indicated oil temperature is 30 ° C, add 3 to x in the function formula.
By substituting 0, the upper limit value is y = 30 + 30 = 60,
The lower limit value is calculated as y = 0.5 × 30 + 15 = 30.
As for the abnormality symptom determination value, since the width between the upper limit value and the lower limit value is 30, the upper limit side is y = 60− (30 ×
0.2) = 54, and the lower limit side is y = 30 + (30 × 0.2
5) = 37.5.

By comparing the determination value thus obtained with the oil level indicator indicated value, the state of the equipment can be determined.

FIG. 22 is an example of the diagnostic result detail screen 111 for displaying the determination result by the diagnostic execution means 19 in this embodiment. This is obtained by adding the result of determination by a functional expression to the diagnostic result detail screen 103 illustrated in FIG.

On this diagnostic result detail screen 111,
Similar to the screen 103, the names, units, and input values of the determination items are shown, as well as the names and input values of corresponding items that are closely related. In addition, the relationship between the related data such as the upper and lower limit values used for the determination and the input value obtained by the current inspection is shown in different colors.

As is clear from the description of the abnormality, in this embodiment, by determining the determination value using the functional expression, it is possible to flexibly determine the device status according to the status. Moreover, the patrol officer can perform the equipment maintenance work without being aware of the mutual relation of the equipment.

The function formula used for the judgment by the function formula judging means 27 is not only automatically generated by data setting from the function formula registration screen, but also a regression curve formula approximating history data in the correlation graph displaying means 21 is used. You can also choose to do so. In this case, the data setting work for automatically generating the function formula is unnecessary.

[0131]

As described above, according to the present invention,
Work can be carried out in the same way as a conventional inspection inspection using check sheets, and facility diagnosis based on collected measurement data and various graph displays using historical data can be immediately performed on site. As a result, even a younger patrolman who has little knowledge about plant equipment can grasp the accurate equipment status, which can contribute to speeding up of inspection inspection work and early detection of equipment abnormalities.
