In the following, in order to explain the present invention in more detail, the form for implementing the present invention will be described based on the attached drawings.

First embodiment

In the first embodiment, a part tendency information control device and a part tendency information control method that generate and output part tendency information will be described. Part preference information is information indicating the priority of disposal of parts in a form comparable to each part. The disposal of parts is to maintain parts or ensure inventory.

FIG. 1 is a diagram showing an example of the configuration of the component tendency information control device 100 of the first embodiment.

The part tendency information control device 100 includes a part information storage 101 and data The input unit 102, the index calculation unit 103, the output information control unit 104, the communication unit 105, and the like. The component tendency information control device 100 is connected to the management server 106 installed in the management department, the maintenance terminal 107 installed in the maintenance site, and the monitoring server 108 installed in the monitoring center via a network to be communicable.

The part information storage unit 101 stores basic information about parts obtained from the management server 106 and the like, maintenance information obtained from the maintenance terminal 107, the monitoring server 108, and the like as part information. That is, the part information includes basic information and maintenance information.

Parts information is information about parts of machines that need maintenance, such as manufacturing equipment, elevators, air conditioners, and power plant equipment. The basic information is specifically the type of parts, the amount of parts, the length of time to prepare the parts, the amount of loss caused by the downtime in the case of parts failure, etc. The maintenance information is specifically the failure history, the number of years of use, the number of times of use, and the value of the state of the measured part.

FIG. 2 is a diagram showing a configuration example of the part information stored in the part information storage unit 101. If it can be stored in the part information storage 101, the form of the part information data is not limited. In addition, the part information storage unit 101 may store information other than the part information shown in FIG. 2. In addition, all the part information shown in FIG. 2 may not be stored. Even if the parts are the same, the information is different depending on the region, supplier, etc., and a table with the region, supplier, etc. information added to the basic information can be made, and the same part exists in the plural sequence. In addition, it is also possible to adopt a form in which basic information, maintenance information, etc. are kept in separate tables and properly combined.

Figure 2 shows that the part information consists of serial number ID, part ID, part type Examples of types, parts amount, lead time, loss amount, years of use, maintenance date and time, and failure date and time.

The data input unit 102 obtains the part information required to execute the processing in the index calculation unit 103 from the part information stored in the part information storage unit 101, and generates shaped data in a form that can be processed. FIG. 3 is a diagram showing an example of shaping data generated by the data input unit 102. As long as the required data is stored, the plastic data is in any form.

Figure 3 shows the part amount of the part whose serial number ID is X1 according to the part unit set. The data input part 102 obtains the part ID and part amount of X1 from the part information storage part 101, and generates shaping data. The data input unit 102 outputs the generated shaping data to the index calculation unit 103. In addition, for example, in the case where the IDs of the serial parts are different, it is not necessary to generate plastic data. The data input unit 102 obtains the part information necessary for executing the processing in the index calculation unit 103 and outputs it to the index calculation unit 103.

The index calculation unit 103 calculates a priority index that is the priority of maintaining parts or ensuring inventory based on the shaping data or part information obtained from the data input unit 102.

FIG. 4 is an example of a flowchart in which the index calculation unit 103 calculates the priority index. The index calculation unit 103 may select a process according to needs from the processes shown in FIG. 4. In addition, arbitrary processing can be added as needed.

The operation of the index calculation unit 103 will be described using FIG. 4.

The index calculation unit 103 determines whether there is part information for calculating the failure rate (step ST401). The index calculation unit 103 determines that there is part information for calculating the failure rate (step ST401: YES), and performs a failure rate calculation process (step ST402). On the other hand, when the index calculation unit 103 determines that there is no component information for which the failure rate is calculated (step ST401: NO), the process moves to step ST403.

Here, the failure rate calculation process (step ST402) will be described.

The failure rate calculation process is a process performed when the priority index is calculated and the failure rate of the used component is determined. Any method can be used to calculate the failure rate. For example, the probability of a failure due to the years of use of the part is taken as the failure rate. In this case, the relationship between the number of years of use and the cumulative number of occurrences of failures is calculated for each part of the same type from the failure history of each part in market use. Then, by dividing the number of cumulative failure occurrences by the number of parts of the same type, the failure rate change over the years of use is obtained, and the failure rate corresponding to the years of use of the part is used. Also, for example, the degree of progress of the fault may be estimated from the value of the state of the measured part, and the degree of progress of the fault may be used as the failure rate. The method of inferring the degree of progress of the fault may be general methods.

In addition, when the failure rate is stored in the part information storage unit 101, the data input unit 102 may obtain the failure rate from the part information storage unit 101 and output the failure rate to the index calculation unit 103. In addition, the failure rate calculated by the index calculation unit 103 may be stored in the part information storage unit 101 or a separately prepared data storage unit, and may be used in processing after step ST403. When the failure rate calculation process (step ST402) ends, the process moves to step ST403.

Next, the index calculation unit 103 determines whether or not there is part information that performs conversion processing (step ST403). The index calculation unit 103 determines that there is part information for which conversion processing is performed (step ST403: YES), and performs conversion processing (step ST404). On the other hand, when the index calculation unit 103 determines that there is no part information for which conversion processing is performed (step ST403: NO), it moves to step ST405 Management.

Here, the conversion process (step ST404) will be described.

The conversion process is a process performed when it is determined that the scale of the part information needs to be converted when the priority index is calculated. For example, if there is a measured value of the state of the part in the part information, and when the intensity of the sound of each part is used in the calculation of the priority index, the measured value of the state of the part is converted into decibels. When it is not necessary to convert to the scale of the part information, the conversion process can be omitted. When the conversion process (step ST404) ends, the process moves to step ST403.

Next, the index calculation unit 103 determines whether there is part information for calculating the average value (step ST405). The index calculation unit 103 determines that there is component information for which the average value is calculated (step ST405: YES), and performs an average value calculation process (step ST406). On the other hand, when the index calculation unit 103 determines that there is no calculated part information for the average value (step ST405: NO), the process moves to step ST407.

Here, the average value calculation process (step ST406) will be described.

The average value calculation process is a process performed when determining the average value of the value of the part information when calculating the priority index. In the case of specific part information of the same part and the existence of multiple values, the average of the multiple values is calculated.

For example, due to reasons such as different prices depending on the region, when there are multiple prices for the same amount of parts, the average of the multiple prices is calculated. When it is not necessary to calculate the average value, the average value calculation process can be omitted. In addition, for example, when the amount of parts in each region is directly used, countermeasures such as handling the same part in each region as different parts may be adopted. In peace For the calculation of the mean value, the method of calculating the median value or the method of calculating other average values may be used. When the average value calculation process (step ST406) ends, the process moves to step ST407.

Then, the index calculation unit 103 determines whether there is part information for performing the approximation processing (step ST407). The index calculation unit 103 determines that there is part information that is subjected to the approximation process (step ST407: YES), and performs the approximation process (step ST408). On the other hand, when the index calculation unit 103 determines that there is no part information for which the approximation process is performed (step ST407: NO), the process moves to step ST409.

Here, the approximation processing (step ST408) will be described.

The approximation process is a process performed when it is determined that the value of the part information needs to be approximated to the closest level among a predetermined limited number of values when calculating the priority index. For example, in the case of taking part information from an integer value of 0 to 1000, the ten digits are collected into four digits to approximate a hundred digits. For example, if the value of the part information is 180 and the predetermined limited value level is 0, 100, 200, ..., 1000, the value of the part information is approximated to 200. When it is not necessary to approximate the value of the part information, the approximation processing can be omitted. When the approximation process (step ST408) ends, the process moves to step ST409.

Next, the index calculation unit 103 performs priority index calculation processing (step ST409).

Here, the priority index calculation process (step ST409) will be described.

The priority index calculation process is to calculate the multiple of the average value for each part for the specific part information, and use the multiple as the priority index. For example, for the five parts whose parts ID are AA1, AA2, AA3, AA4, and AA5, specific When the value of the part information is 30, 40, 50, 60, 70, calculate the average value 50 according to the mathematical formula of (30 + 40 + 50 + 60 + 70) / 5, and divide the value of the part information of the five types Taking the average value of 50, as a priority index of AA1, AA2, AA3, AA4, and AA5, 0.6, 0.8, 1.0, 1.2, and 1.4 are obtained. In addition, the parts whose priority index is calculated can also be limited. For example, when there are parts with the same part type, select a part from the parts of the part type, and calculate the priority index according to the above method.

In addition, when the priority of a part with a large value of part information is lowered, before calculating the priority index, the sign of the part information is reversed from positive to negative, and then the priority index may be calculated. In addition, in the case where the part information is text, etc. instead of a numerical value, although it is a numerical value but a value data, and the numerical value size is meaningless, the priority index calculation processing is omitted. For example, when the part type of the part information is text such as AA, BB, etc., the priority index calculation processing is not performed. The index calculation unit 103 outputs the calculated priority index to the output information control unit 104.

The output information control unit 104 uses the priority index obtained from the index calculation unit 103 to generate part tendency information. Part trend information is as shown above, and it shows the priority of maintaining parts or ensuring inventory in a form comparable to each part. Part trend information is generated as a table or priority index graph representing priority indexes. The output information control unit 104 outputs component tendency information to the display device 200. The display device 200 is, for example, a liquid crystal display.

FIG. 5 is a diagram showing an example of a table of priority indexes.

Fig. 6 is a diagram showing an example of a priority index pattern.

The output information control unit 104 is, for example, accepting a display command from the user In the case of, the part tendency information is generated and output to the display device 200. In addition, after the processing by the index calculation unit 103, the output information control unit 104 performs processing and the like, as long as the processing timing of the output information control unit 104 after the processing by the index calculation unit 103 is any timing.

FIG. 5 is a diagram showing an example in which the output information control unit 104 aggregates the serial numbers and the priority indexes of the parts into one table. In addition, the output information control unit 104 may make the value of the part information when the index calculation unit 103 calculates the priority index correspond to the calculated priority index value, and aggregate them into a table. In this case, the output information control unit 104 creates a table in which the item weight of the part information corresponds to the value of the part information and the priority index of the part information.

FIG. 6 is a diagram showing an example in which the output information control unit 104 uses the priority index of the failure rate in FIG. 5 to generate a priority index graph. Next to each point, a text string combining the serial number ID and the part ID is displayed. In addition, the character string may be displayed only for specific parts. In Fig. 5, for four parts, the priority index calculated based on the failure rate is shown, but the priority index is also calculated based on the failure rate of other parts.

In Figure 6, the horizontal axis represents the level of failure rate. The horizontal axis is displayed as a logarithm, and the center is 1 as the average. In the case of Fig. 6, the higher the right, the higher the priority. In addition, the horizontal axis may not be displayed in logarithm. The vertical axis displays parts with a large value of the priority index of the failure rate on the upper side of parts with a small value of the priority index of the failure rate, but it is not limited to this, and may be arbitrary. In FIG. 6, in the vertical axis direction, the arrangement is such that the character strings of the parts are staggered so as not to overlap, but the parts with the same priority index value may be displayed so that the positions in the vertical axis direction match. In addition, it can also be displayed when there are many parts displayed. The number of parts is limited to a fixed number.

As shown above, the component tendency information control device 100 of the first embodiment includes: a component information storage unit 101 that stores component information of components used by the machine; an index calculation unit 103 that calculates maintenance components based on the component information Or the priority index to ensure the priority of the inventory; and the output information control unit 104 uses the priority index to generate and output component tendency information indicating the priority of maintaining the parts or ensuring the inventory in a form comparable to each part. In this way, after comparing the maintenance parts or ensuring the priority of inventory for each part, appropriate disposal can be taken. For example, it is possible to grasp the priority of comparing the amount of parts, failure rate, etc. for each part, and to determine the inventory of parts with a high amount of compressed parts, or to perform maintenance of parts with a high failure rate at a high frequency.

In addition, the output information control unit 104 generates a priority index graph with one priority index as the horizontal axis, and displays the logarithmically on the horizontal axis. With this, it is possible to intuitively grasp the degree to which the priority index calculated based on the failure rate is the relative average value such as 2 times, 1/2 times the average value.

Second Embodiment

Regarding the component tendency information control device 100 of the second embodiment, the description of the configuration having the same or equivalent function as the configuration described in the first embodiment is omitted or simplified. FIG. 6 shows an example in which the output information control unit 104 uses a priority index which is a failure rate of part information to generate a priority index graph. In the second embodiment, the output information control unit 104 uses the priority index of the two parts information to generate the priority index graphic.

FIG. 7 is an example of the priority index pattern generated by the output information control unit 104. Figure 7 is the priority of the output information control unit 104 using two parts information Indicators to generate examples of priority indicator graphics. The priority index graph of FIG. 7 is an example in which the priority index of the failure rate in FIG. 5 is the horizontal axis, and the priority index of the component amount in FIG. 5 is the vertical axis. In Figure 5, for four parts, the priority index calculated based on the failure rate and the amount of parts is shown, but the priority index is also calculated based on the failure rate and the amount of parts of other parts. In Fig. 7, beside each point, a character string combining the serial number ID and the part ID is displayed. The display system is not limited to the character string, and for example, it may be displayed with a mark or the like. In addition, the character string may be displayed only for specific parts.

The horizontal axis indicates the level of the failure rate, which is represented by the logarithm, and the center is 1 with the same degree as the average value. The vertical axis indicates the level of the part amount, which is represented by the logarithm, and the center is 1 with the same degree as the average value. In addition, the horizontal axis and the vertical axis may not be expressed in logarithm. In addition, when the number of displayed parts is large, the number of displayed parts may be limited to a fixed number.

As described above, according to the second embodiment, for example, for the two priority indexes of the component amount and the failure rate, the level of the priority index of each component can be grasped at the same time. Thereby, it can be judged that high-frequency maintenance of parts with a high failure rate and parts cost is high.

In addition, the output information control unit 104 generates a priority index graph using one priority index as the horizontal axis and the other priority index as the vertical axis, and displays the horizontal axis and the vertical axis as a logarithm. With this, for example, it is possible to intuitively grasp the degree to which the priority index calculated based on the failure rate and the amount of parts is a relative average value such as 2 times or 1/2 times the average value.

Third embodiment

For the component tendency information control device 100 of the third embodiment, the For the configuration having the same or equivalent functions as those described in the first and second embodiments, the description is omitted or simplified.

In the second embodiment, even if the same part ID of AA1 is used, the priority index of each part is calculated when the serial numbers are different. In the third embodiment, when there are parts with the same part ID between the serial numbers, the average value calculation process shown in FIG. 4 is performed on the value of the specific part information of zero, and then the average value of the part information is used Value, calculate the priority index.

The index calculation unit 103 performs the average value calculation process on the value of the specific part information of the part ID when there is a common part ID between the serial numbers, and calculates the average value of the value of the part information. In this case, the index calculation unit 103 uses the average value of the value of the part information to calculate the priority index (as the first priority index).

FIG. 8 is a diagram showing an example of the priority index pattern generated by the output information control unit 104. The priority index graph in FIG. 8 is an example in which the priority index of the failure rate is taken as the horizontal axis, and the priority index of the part amount is taken as the vertical axis. Figure 8 shows the situation where the parts IDs of AA1, AA2, and BB1 are common among the serial numbers. In Figure 8, the failure rate of AA1, AA2, and BB1 and the amount of parts are averaged, and the first priority index is calculated. The failure rate and the amount of parts in AA1, AA2, and BB1 are considered to have multiple values. The horizontal axis and the vertical axis of FIG. 8 indicate the size of the first priority index. The part name can also be displayed on the grid point representing each part. In addition, in FIG. 8, a person using two first priority indicators is used, but any one may be used. The display of the part ID is not limited to text strings. For example, it can also be displayed with a mark. Also, only specific parts can be created, and the character string can be displayed.

The failure rate is represented by the horizontal axis system, and the logarithmic representation is shown, and the center is made to be the same as the average value of 1. The amount of parts is indicated by the axis of the axis, and it is expressed in logarithm, and the center is 1 which is the same as the average value. It is also possible that the horizontal axis and the vertical axis are not logarithmic. In addition, when the number of displayed parts is large, the number of displayed parts may be limited to a fixed number.

As described above, in the third embodiment, the index calculation unit 103 calculates the average value of the specific part information of the part when there are common parts between the serial numbers, and uses the average value to calculate the first priority After the index, the output information control unit 104 uses the first priority index to generate part tendency information. In this way, regardless of the serial number and focusing only on the parts, the priority index of each part can be compared to take appropriate measures.

Fourth embodiment

Regarding the component tendency information control device 100 of the fourth embodiment, the configuration having the same or equivalent functions as those described in the first embodiment, the second embodiment, and the third embodiment will be omitted or simplified. In the third embodiment, when there is a common part ID between serial numbers, an average value calculation process is performed on the value of the specific part information of the part ID, and then the first priority index is calculated. In the fourth embodiment, the index calculation unit 103 further calculates the priority index (as the second priority index) of the value of the part information before the average value calculation process for the part information of the specific part ID.

The index calculation unit 103, when there is a common part ID between serial numbers, performs an average calculation process on the value of the specific part information of the part ID, calculates the average value of the part information, and then uses the average value to calculate the first 1 Priority index, and use each value of the specific part information of the part ID to calculate The second priority indicator. The output information control unit 104 generates a priority index graph that overlaps and displays the first priority index and the second priority index.

FIG. 9 is an example of the priority index pattern generated by the output information control unit 104. The priority index graph of FIG. 9 is an example in which the priority index of the failure rate is the horizontal axis, and the priority index of the part amount is the vertical axis. The solid line in Fig. 9 shows the average value of the failure rate and the amount of parts of AA1, AA2, and BB1 that are common between the serial numbers, and then the first priority index calculated by using the average value. The dots in Fig. 9 represent the second priority index calculated using the values of the failure rate of AA1, AA2, and BB1 that are common between the serial numbers and the value of the part amount. In addition, in FIG. 9, not all the second priority indexes are shown, but only the specific second priority indexes are indicated by dots.

The part name can also be displayed on the grid point representing each part. In Fig. 9, beside each point, a character string combining a serial number ID and a part ID is displayed. The display system is not limited to the character string, for example, it may be displayed with a mark or the like. Also, only specific parts can be created, and the character string can be displayed.

The failure rate is indicated by the horizontal axis system, and a logarithmic display is made, and the center is made to be the same as the average value of 1. The amount of parts is indicated by the axis of the axis, and it is expressed in logarithm, and the center is 1 which is the same as the average value. It is also possible that the horizontal axis and the vertical axis are not logarithmic. You can also limit the number of displayed parts to a fixed number when the number of displayed parts is large.

As described above, in the fourth embodiment, not only the configuration of the third embodiment, but also the index calculation unit 103 when there are common parts between the serial numbers, each value of the value of the specific part information of the part is used to calculate Priority index, the output information control unit 104 displays the second priority index and The part preference information of the first priority index calculated by the average value. Therefore, it is possible to grasp the difference between the first priority index calculated using the part information averaged in the unit of parts and the second priority index calculated using the value of the part information before the averaging. As a result, for example, it is possible to take measures to preferentially maintain parts having a large difference between the first priority index and the second priority index.

Next, an example of the hardware configuration of the component tendency information control device 100 will be described.

That is, the component tendency information control device 100 includes a processing circuit for realizing these functions. The processing circuit is a processor 1001 that executes a program stored in the memory 1002.

The software or system is written as a program and stored in the memory 1002. The processor 1001 realizes the functions of each part by reading out the program stored in the memory 1002 and executing it. That is, the part tendency information control device 100 includes a memory 1002 for storing a program, and when the program is executed by the processor 1001, the fourth The steps shown in the flow chart of the figure. In addition, it can also be said that this program causes a computer to execute a program or method of the data input unit 102, the index calculation unit 103, and the output information control unit 104.
