Description

  The present invention relates to a maintenance evaluation system that inspects and maintains machines and devices.

  Conventionally, a maintenance evaluation system using a failure mode and effects analysis (FMEA) sheet generated based on online information from a real-time database is known (see, for example, Patent Document 1).

  This maintenance evaluation system captures failure information online from a real-time database by adding maintenance functions including machine / device identification, maintenance planning, preventive maintenance, and subsequent maintenance to the FMEA sheet. Thus, a failure database is automatically generated via an interface for inputting each coping method by a selection method.

JP 2006-4219 A

  However, the above-described maintenance evaluation system monitors the operation state of each device and integrates operation signals based on the maintenance data generated by the FMEA sheet generation unit, and considers the entry of comments when a failure occurs. Follow up. As a result, maintenance information such as the replacement time of the machine / device is displayed on the process monitoring system.

  Therefore, although the failure database itself is automatically generated, in reality, it is necessary to make a high-level judgment by an on-site worker (hereinafter referred to as “worker”) when replacing the machine / device. Therefore, it has not been possible to efficiently determine maintenance evaluation such as determining whether or not the machine / device itself needs to be replaced and determining whether to change the inspection cycle or inspection level.

  For example, when an operator is inspecting a plant facility and the machine or device such as a pressure transmitter, butterfly valve, or other various controllers used in the plant facility is subject to inspection (failure target), the worker Inspects the machinery and equipment, disassembles as necessary, and replaces parts that cause failure. At this time, in the normal inspection work (failure repair work), the worker simply made a judgment as to whether or not to replace the parts at the work site.

  Therefore, considering the importance of the parts to be replaced, the difference from the standard replacement time, and other various factors, is it better to replace the machine / equipment itself or speed up the inspection cycle? The maintenance evaluation, such as whether it is better to raise the inspection level, was judged objectively and efficiently, and the judgment result was not presented to the operator, manager or customer.

  Therefore, the present invention has been made to solve the conventional problems as described above, and an object of the present invention is to provide a maintenance evaluation system capable of efficiently determining maintenance evaluation.

  In order to solve the above problems, a maintenance evaluation system according to the present invention is a maintenance evaluation system for maintaining a machine / equipment. In the maintenance evaluation system, a plurality of inspection item data for the machine / device is stored, and stored in the storage unit. The inspection item data is recalled and displayed in a tabular form so as to include the inspection item and inspection result check column, and the operator inputs the inspection result in the inspection result check column displayed on the display unit. Input means, inspection result data storage means for storing and storing the input results from the input means as inspection result data in the storage means, evaluation levels preset for each of the inspection items, and the inspection results A determination means for determining maintenance evaluation based on a maintenance evaluation level value calculated based on an inspection result in a check column; and And output means for outputting the integrity evaluation result of judgment Te, characterized in that it comprises a.

  With this configuration, in the maintenance evaluation system according to the present invention, a plurality of inspection item data for the machine / device to be maintained is stored in the storage means, and the inspection item data stored in the storage means is called up by the display means for inspection. Displayed in a table format including items and check result check fields, and the check results are displayed by the operator in the check result check fields displayed on the display means, and the input results by the input means are the check result data. The storage means accumulates and stores the inspection result data in the storage means. Thereby, a determination means determines maintenance evaluation based on the maintenance evaluation level value calculated based on the evaluation level preset with respect to each of the inspection items and the inspection result in the inspection result check column. Further, the maintenance evaluation result as the determination result is output by the output means.

  Note that the output here includes, for example, the case where the determination result can be displayed on the display means and, for example, the case where data is transferred to the server or the terminal device through the telecommunication line.

  Hereinafter, an embodiment in which a maintenance evaluation system according to the present invention is applied to a maintenance evaluation system 1 will be described with reference to the drawings.

  As shown in FIG. 1, a maintenance evaluation system 1 according to the embodiment is installed in a management office or the like and stores a maintenance database 11 and an on-site worker (hereinafter simply referred to as “worker”). Is equipped with a portable information terminal 13 to be carried at the work site. The server 12 managed by an administrator or the like and the portable information terminal 13 used by the worker can transmit and receive data to and from both sides through an electric communication line such as an in-house intranet line or the Internet line.

  This maintenance evaluation system 1 uses, for example, machines / devices (hereinafter referred to as “instrumentation equipment”) such as pressure transmitters, butterfly valves, and other various controllers used in plant facilities at work sites as maintenance targets. Yes. Inspections that have been accumulated, including past inspection histories, by performing maintenance such as inspection, repair, maintenance, etc. (hereinafter collectively referred to as “inspection” unless otherwise specified) due to the occurrence of a malfunction or occurrence of the instrumentation equipment. The optimum maintenance evaluation is performed using the result data.

  The maintenance database 11 according to the embodiment is stored in a mass storage device (HDD) as a storage unit included in the computer device 14 of the server 12. The maintenance database 11 includes a plurality of inspection item data and drawing data for each instrumentation device in the maintenance evaluation system 1 according to the present invention. The maintenance database 11 also serves as inspection data storage means for storing (or updating) inspection result data after inspection of instrumentation equipment as part of inspection item data.

  Therefore, the server 12 can create the maintenance database 11 for the new instrumentation device while displaying it on the display screen 15a of the monitor device 15, and can change, modify, modify, and modify the maintenance database 11 for the instrumentation device that has already been created. Management including renewal is possible.

  The server 12 uses a so-called personal computer, and program software for realizing the maintenance management system of the present invention is installed in the large-capacity storage device of the computer device 14 to determine the control circuit (CPU). It can be used as a means, and a ROM or a RAM can be used as a part of the storage means.

  The maintenance database 11 may be stored in various media such as a compact disk, flexible disk, magneto-optical disk, digital video disk, magnetic tape, and external hard disk.

  In the maintenance database 11, inspection result data including the progress and results of inspections performed at the work site is input by the operator through the portable information terminal 13 and accumulated by output through the telecommunication line.

  The maintenance database 11 can be used with a terminal set for each office when management offices are installed at a plurality of locations. At this time, the maintenance database 11 can use any one server 12 as a main server, and can transmit and receive data through a telecommunication line. As a result, the data in the maintenance database 11 can be shared using the server 12 at one office as the main server, and the inspection result data of all the offices can be centralized and accumulated.

  The maintenance database 11 may transmit and receive data using a core database on the Internet. The core database can also have a function as a backup of the maintenance database 11.

  Although a specific hardware configuration is not illustrated, the server 12 includes a CPU that is a control circuit, a mass storage device (HDD) as a built-in memory, a ROM, a RAM, and the like, and further includes an A / D converter and the like. An input interface circuit and an output interface circuit including a driver and a relay switch are included.

  The server 12 is configured by a processing computer that executes a calculation process according to a processing program stored in a ROM or a large-capacity storage device, for example, a so-called multitask processing computer that performs a plurality of processes in parallel. The server 12 can switch and execute a plurality of tasks (processes).

  The server 12 is configured to perform calculation processing based on inspection result data input from the portable information terminal 13. For example, the server 12 uses, as partial information of the maintenance database 11, an evaluation level for each part of the instrumentation device, and an evaluation level value that is divided into a plurality of stages and numerically expressed in advance so as to correspond to this evaluation level. Use. This evaluation level value indicates that if a failure occurs in an instrumentation device, the impact on the overall function of the instrumentation device, the impact on the entire plant facility in which this instrumentation device is installed, and the progress of the failure becomes worse. In consideration of the degree of importance such as the degree of deterioration and the degree of deterioration in general, it is set in advance in a plurality of stages.

  Specifically, when the evaluation level is very slight (for example, evaluation level stage 1), the function of the instrumentation device is equivalent to the initial level if there are no problems with other parts, for example, by replacing parts. Assume that the evaluation level value is “1” in the case of a component that can be guaranteed or a malfunction (for example, loose bolt).

  In addition, when the evaluation level is negligible (for example, evaluation level stage 2), for example, a component that can sufficiently ensure the function of the instrumentation device if there is no problem with other components by performing component replacement or the like. Alternatively, the evaluation level value for a defect or the like is set to “2”.

  In addition, when the evaluation level is slightly serious (for example, evaluation level stage 3), for example, by replacing parts, etc., the function of the instrumentation device may be reduced depending on the balance with other parts and the like. Assume that the evaluation level value is “3” for a part that is adversely affected or a malfunction.

  In addition, when the evaluation level is extremely serious (for example, evaluation level stage 4), for example, even if parts are replaced, it is a part or a defect that causes an adverse effect to the extent that the operating rate of the plant equipment is lowered. In this case, the evaluation level value is “4”.

  And when the evaluation level is fatal (for example, evaluation level stage 5), for example, when it is a defect that may have an obvious adverse effect on the operation of the plant equipment, when the parts cannot be replaced, the service life has passed. In this case, the evaluation level value is “5”.

  It should be noted that the above-described evaluation level stage and evaluation level value are merely examples, and even the actual evaluation level stage and evaluation level value are not used as a reference, and are appropriately set depending on the type of instrumentation equipment. The

  Further, in the following description, for the sake of convenience of explanation, description will be made on parts replacement. However, in practice, the present invention is not limited to parts replacement. For example, there are problems such as elimination of loosening of bolts and nuts. In addition, the evaluation level stage and the evaluation level value are described in numerical correspondence, but actually, the evaluation level value is not always “1” even if the evaluation level stage is 1 which is the lowest stage. .

  As a result of the inspection work, the number of parts replacement at evaluation level value 1 is 2, the number of parts replacement at evaluation level value 2 is 3, the number of parts replacement at evaluation level value 3 is 5, the number of parts replacement at evaluation level 4 When the number of replacement parts at evaluation level 5 is 1, the total of all evaluation level values at evaluation level stages 1 to 5 is as follows.

(1 × 2) + (2 × 3) + (3 × 5) + (4 × 5) + (5 × 1) = 48
The calculation result of the evaluation level value is 48.

  For example, a portable terminal such as a tablet computer (tablet terminal) or a smartphone equipped with a touch panel display screen as display means is used as the portable information terminal 13, and a dedicated application is installed in advance. Thereby, the maintenance database 11 of the instrumentation equipment to be inspected can be acquired from the server 12 and used at the work site.

  The portable information terminal 13 includes a communication interface, and adopts a touch panel method for the display screen 13a, so that the display screen 13a is also used as an input unit. The portable information terminal 13 accesses the server 12 via the interface to acquire the maintenance database 11 and stores the maintenance database 11 in a built-in memory.

  When the worker activates the application of the portable information terminal 13, the CPU reads the maintenance database 11 acquired from the built-in memory, and expands and displays the maintenance database 11 in a predetermined tabular state on the display screen 13a. An operator inputs an inspection result with the touch panel of the display screen 13a. The inspection result data after the inspection is stored in the built-in memory as a new maintenance database 11 and transmitted to the server 12 via the interface. The calculation of the evaluation level value by the server 12 described above can be performed by the CPU of the portable information terminal 13.

  Hereinafter, a display example at the time of inspection work on the display screen 13a of the portable information terminal 13 will be described. Various information necessary for the inspection work is displayed on the display screen 13a of the portable information terminal 13 based on the acquired maintenance database 11.

  As this information, for example, as shown in FIG. 2, an inspection item for inspecting an instrument to be inspected at the time of inspection work, an input column corresponding to the inspection item, and an instrumentation device shown in FIG. There is an exploded view. By displaying the inspection items and the exploded drawing on the display screen 13a, leakage of the inspection items is reduced, and an accurate inspection is performed by an inspection operator (hereinafter, simply referred to as “operator”).

  As shown in FIG. 2, the display screen 13a can be switched in a tab format. The inspection item tab is selected in FIG. 2, and the exploded view A tab is shown in FIG. Is selected. Further, for example, in the display of the exploded view A shown in FIG. 3, for example, when a desired part is touched, auxiliary information such as a product number, inspection contents / method, etc. can be called from the maintenance database 11 to display a comment.

  Furthermore, for example, in the display of the exploded view A shown in FIG. 3, for example, when a desired part is continuously touched (double touch), the display is switched to the inspection item tab display, and the inspection item column display of the corresponding part is displayed. It can be displayed in reverse video.

  Further, as shown in FIG. 2, the display screen 13a in a state in which the inspection item tab is selected includes input fields of a “before processing” column and a “after processing” column for each inspection item. In addition, an “x” mark (or a “re” mark or the like) may be input by touching the corresponding cell. The “x” mark in the “before processing” column indicates that the operator has input when a failure of the instrumentation is found. At this time, the “x” mark is also written in the “after processing” column. The “x” mark in the “post-processing” column is deleted when the handling of the trouble of the instrumentation device is completed by the operator. Note that the “x” mark in the “after processing” column may be input by the operator when the handling of the malfunction of the instrumentation device is completed.

  Moreover, you may make it display the evaluation level value which is the weight which considered the degree of the importance for this check item for every item. The inspection item display screen shown in FIG. 2 is also displayed on the display screen 13a of the portable information terminal 13 in the same manner. You may make it use it as a reference which selects the evaluation level step of an instrumentation instrument by an operator with reference to the weight displayed on the display screen 13a.

  For example, a camera (not shown) installed at the work site or a camera (not shown) attached to the portable information terminal 13 is used as the monitor device 15 (which may be another monitor device) of the server 12, and the video is displayed on the display screen 15a. May be.

  The monitor device 15 can display an image synchronized with the display on the display screen 13a of the portable information terminal 13 held by the worker on the display screen 15a, and manages the inspection work of the worker at a place away from the work site. The person etc. can also support.

  Note that the exploded perspective view shown in FIG. 3 is an exploded perspective view of the lower half (pressure receiving body) of the pneumatic differential pressure transmitter as the instrumentation device stored in the maintenance database 11, and the appearance tab is displayed. External perspective view of the pneumatic differential pressure transmitter in the selected state, sectional view of the pneumatic differential pressure transmitter in the state where the main body internal tab is selected, and the pneumatic type in the state where the exploded view A tab is selected An exploded perspective view of the upper half (amplifying unit) of the differential pressure transmitter can be displayed. At this time, in addition to these, for example, various information such as a route diagram of the entire plant apparatus, standard specifications, characteristics, part type names, code lists, and the like can be displayed.

  The exploded perspective view of the instrumentation device shown in FIG. 3 is used for measurement of flow rate, liquid level, pressure, etc., and shows the bottom of the pneumatic differential pressure transmitter 30 that converts these process variables into predetermined air pressure signals. The perspective view of the state which decomposed | disassembled half is shown.

  Specifically, the pneumatic differential pressure transmitter 30 includes a body 31, a cover 32, a diaphragm capsule 33, connectors 34 and 35, plates 36, gaskets 37, 38, which form connection ports on the high pressure side and the low pressure side. 39, 41, O-ring 42, and bolts 51, 52, 53. Note that the names and the like of the respective components are examples for reference and do not necessarily match the component names and the like of the items shown in FIG. 2 except for the diaphragm capsule 33. Also, description of the function of a specific configuration is omitted.

  Further, the monitor device 15 displays the contents of the calculation processing of the server 12 and the calculation results in a table. For example, as shown in FIG. 4, the column of “degree of failure” corresponding to the evaluation level stage and the column “5 total 1-4 5 4 3 2 1” indicating the evaluation level value are displayed. The number of defects of each evaluation level value and the calculated value (maintenance evaluation level value) are displayed below each numerical value column. In addition, the display of each number in the “5 total 1-4 5 4 3 2 1” column may be at the evaluation level stage.

  For example, in the case of a row surrounded by a dashed ellipse in FIG. 4, the lower column of the evaluation level value “1” is 2 (pieces or locations), the lower column of the evaluation level value “2” is 3, and the evaluation level value “3”. Is 5 below the evaluation level value “4”, and 1 below the evaluation level value “5”.

  In addition, the “1-4” column in FIG. 4 is a calculated value obtained by multiplying the evaluation level values and the numbers of the respective evaluation level stages 1 to 4 by the numbers and adding the multiplication results of the respective columns. As a numerical value. In the “5 totals” column of FIG. 4, the multiplication result of the evaluation level value 5 is numerically displayed as a calculated value.

  Note that the calculated value at this time is an accumulated value when an inspection level is input in the past and an evaluation level value is input.

  Furthermore, as shown on the right side of the broken-line ellipse, the monitor device 15 displays a “check level” column and a “check cycle” column.

  This inspection level is, for example, an inspection level “A” for performing a detailed inspection including disassembly, an inspection level “B” for confirming input / output (signal level) to an electrical signal, and an inspection level “C” The items that are visually inspected and the inspection level “none” indicate that they are not subject to inspection. In addition, for example, when the inspection cycle “6” may be inspected every 6 months, the inspection interval “12” may be inspected every 12 months, or the inspection interval “24” is 24. This shows the case where the inspection is performed on a monthly cycle. The length of the inspection cycle can be set and changed according to the instrumentation as appropriate by a user such as an administrator of the maintenance evaluation system 1. The inspection level and the inspection cycle can be used as one of maintenance evaluations using the server 12 (CPU) or the portable information terminal 13 (CPU) as a determination means (details will be described later).

  Further, as shown in FIG. 5, on the display screen 15a of the monitoring device 15, the evaluation level value is displayed as a score, the horizontal axis represents the inspection date, the vertical axis represents the number, and the maintenance evaluation on the inspection date is shown. As a bar graph.

  With reference to the display in FIG. 4 and FIG. 5, the user can accurately grasp the occurrence state of the defect and the maintenance evaluation, and can finely set and change the inspection cycle and inspection level.

  For example, the CPU of the server 12 (or the CPU of the portable information terminal 13) has a 43 in the “1-4” column or a “5 total” column that is the calculation result of the evaluation level value of the instrumentation device indicated by the dashed ellipse. 5, the reference value for each inspection level set in advance is referred to, for example, the inspection level “C” is changed to the inspection level “A”. Conversely, when the numerical value in the “1-4” column, which is the calculation result of the evaluation level value, becomes lower than the previous value and becomes the reference value of another inspection level, for example, the inspection level “A” is changed to the inspection level. Change to “C”. Similarly, the CPU of the server 12 (or the CPU of the portable information terminal 13) displays 43 in the “1-4” column, which is the calculation result of the evaluation level value of the instrumentation device indicated by the dashed ellipse, and the “5 meter” column. The reference value for each inspection cycle set in advance is referred to, and for example, the inspection cycle “6” is changed to the inspection cycle “12”. On the other hand, when the numerical value in the “1-4” column, which is the calculation result of the evaluation level value, is lower than the previous value and becomes the reference value of another inspection cycle, for example, the inspection cycle “12” is changed to the inspection cycle. Change to “6”.

  Next, an example of an inspection work routine using the maintenance evaluation system 1 according to the embodiment will be described with reference to FIG.

  First, an operator who wants to inspect equipment to be inspected checks the operation of the server 12 in the field office shown in FIG. 1 and inspects instrumentation equipment to be inspected, such as inspection tools and inspection measuring instruments. Preparations necessary for the process are completed (step S11).

  Next, the worker uses the portable information terminal 13 shown in FIG. 1 to access the server 12 to obtain the latest data necessary for the inspection of the instrumentation device to be inspected from the maintenance database 11 and store it in the internal memory. (Step S12).

  At this time, the portable information terminal 13 activates access to the server 12, authentication, a download application, and the like. On the other hand, the server 12 activates access and authentication of the portable information terminal 13, an upload application, and the like, and uploads necessary data from the balance database 11 to the portable information terminal 13. The telecommunications line means at this time is arbitrary using a known technique. A known technique can also be used for the upload / download technique.

  Then, the operator launches the application of the portable information terminal 13 at the inspection site, uses the touch panel system as the input means of the display screen 13a, and provides information on the instrumentation target to be inspected, that is, the inspection items shown in FIG. Data necessary for the inspection of the instrumentation device to be inspected including the exploded perspective view shown in FIG. 3 is displayed on the display screen 13a of the portable information terminal 13 (step S13).

  At this time, the CPU of the portable information terminal 13 performs a predetermined process according to the application operation by the worker, and displays it on the display screen 13a based on the data downloaded from the maintenance database 1 stored in the internal memory.

  Subsequently, the worker performs maintenance such as appearance inspection, overhaul inspection, and cleaning while referring to data such as instrumentation equipment to be inspected, data on inspection items, and drawings displayed on the display screen 13a (step). S14).

  Then, the operator checks whether or not there is a defect in the instrumentation device to be inspected (step S15).

  When there is a defect in the instrumentation target to be inspected, a measure corresponding to the defect such as replacement or repair is performed (step S16).

  If there is no defect in the instrumentation target to be inspected, the process proceeds to step S17.

  The operator performs assembly of the instrumentation equipment that has undergone maintenance such as overhaul and cleaning (step S17).

  Subsequently, the worker uses the portable information terminal 13 to select the inspection item tab shown in FIG. 2 and input the inspection result (step S18).

  At this time, the CPU of the portable information terminal 13 updates the data downloaded from the maintenance database 1 stored in the internal memory as inspection result data according to the input result (check result) for each inspection item by the operator, To remember.

  Then, the worker accesses the server 12 and transmits and outputs the created inspection result data from the portable information terminal 13 to the maintenance database 11 via the server 12 (step S19).

  At this time, the server 12 updates and stores the received inspection result data as corresponding data in the maintenance database 11.

  Upon completion of this transmission output, the worker finishes the field work (step S20).

  On the other hand, the administrator operates the server 12 to execute maintenance evaluation.

  The CPU of the server 12 mainly calculates the evaluation level value using the updated inspection result data. In the calculation result, the total calculation result of the evaluation levels 1 to 4 (the numerical value in the “1-4” column in FIG. 2) is set as a predetermined value (hereinafter referred to as “reference value”). In the case of “0”, it is determined as “none”, in the case of the reference value “1-10”, it is determined as the inspection level “C”, and in the case of the reference value “11-30”, the inspection level is “B”. If the reference value is “31 or more”, the inspection level is “A”.

  Further, for example, when there is even one corresponding to the evaluation level 5, the CPU of the server 12 determines the inspection level “A” regardless of the total calculation result of the evaluation levels 1 to 4. Further, for example, when there is one corresponding to the evaluation level 5, the CPU of the server 12 sets the inspection level “C” to the inspection level “B” or the inspection level “B” to the inspection level “A”. In this way, it is determined to change the inspection level to one level higher.

  The administrator can refer to this judgment result and set or change the inspection level in more detail by comprehensive judgment including the scale of plant equipment, interrelationship with other instrumentation equipment, operation rate, etc. Is possible. As a result, the manager can, for example, consult with the person in charge of the contracted plant facility at a later date, such as changing the inspection level or replacing the instrumentation device itself.

  Therefore, in this case, the output means in the claims shall upload the change result data from the portable information terminal 13 to the server 12.

  Further, the above-described determination can be performed by the CPU of the portable information terminal 13 by the operator's operation at the work site. In such a case, the worker can directly consult with the person in charge of the contracted plant equipment at the work site, for example, changing the inspection level or replacing the instrumentation device itself.

  Therefore, in this case, the output means in the claims shall display the results shown in FIGS. 4 and 5 on the display screen 13a.

  Moreover, in the said embodiment, although the inspection level was shown as an example as an example of maintenance evaluation, the same determination can be performed also in an inspection period. Note that the inspection period is not necessarily linked with the inspection level, and the determination result is not necessarily changed.

  In addition, when such an inspection level or inspection cycle is changed, the evaluation level value as a weight is increased (for example, increased by 20%), or a reference value for determining the inspection level or inspection cycle (predetermined value) Value) may be discounted (for example, 20% down).

  In addition to displaying the inspection level and inspection cycle, a message recommending replacement of the instrumentation device according to the numerical value of the calculation result can be displayed on the display screen 15a (13a).

Thus, the maintenance evaluation system 1 according to the embodiment
The maintenance evaluation system 1 according to the embodiment calls a storage unit (memory of the computer device 14 / memory of the portable information terminal 13) for storing a plurality of maintenance databases 11 for the machine / device, and the maintenance database 11 stored in the storage unit. The display screen 13a (15a) that is expanded and displayed in a tabular form so as to include the inspection item and the inspection result check column, and the display for the operator to input the inspection result in the inspection result check column displayed on the display screen 13a Inspection result data storage means (CPU of the computer device 14 / CPU of the portable information terminal 13) that stores and stores the screen 13a (mouse / keyboard of the server 12) and the input result on the display screen 13a as storage result data in the storage means. And the evaluation level preset for each inspection item and the points in the inspection result check column. Determination means (CPU of the computer device 14 / CPU of the portable information terminal 13) for determining maintenance evaluation based on the maintenance evaluation level value calculated based on the result, and output means for outputting the maintenance evaluation result determined by the determination means (Uploading inspection result data from the portable information terminal 13 to the server 12 and displaying it on the display screen 13a) makes it possible to efficiently determine maintenance evaluation.

  By the way, in the maintenance evaluation system 1 which concerns on the said embodiment, the case of the evaluation level value which divided the evaluation level of the instrumentation apparatus in five steps was demonstrated. However, the maintenance evaluation system according to the present invention may display the evaluation level of the instrumentation device in a category other than five stages. For example, this evaluation level may be displayed in three stages, or may be displayed in ten stages.

  Further, in the maintenance evaluation system 1 according to the above-described embodiment, the inspection cycle is displayed as follows: the inspection cycle “6” is a 6-month cycle, “12” is a 12-month cycle, and “24” is a 24-month cycle. I explained the case. However, in the maintenance evaluation system according to the present invention, the inspection cycle may be expressed by a different one from the above-described cycle. For example, the inspection cycle “3M” is 3 months, the inspection cycle “6M” is 6 months, the inspection cycle “1Y” is 1 year, the inspection cycle “2Y” is 2 years, and the inspection cycle “4Y” is You may display like a 4-year cycle.

  As described above, the maintenance evaluation system according to the present invention has an effect that the maintenance evaluation can be efficiently determined, and is useful for the entire maintenance evaluation system.
