Below, the equipment inspection work support system which concerns on Embodiment 1 of this invention is demonstrated based on drawing. FIG. 1 shows the configuration of an equipment inspection work support system (hereinafter abbreviated as this system) according to the first embodiment. As shown in FIG. 1, the present system includes a management server 1, an administrator PC 2 that is an administrator terminal device, and mobile terminals 3a, 3b, 3c,. ). Since the internal configuration of each mobile terminal 3 is the same, illustrations other than the mobile terminal 3a are omitted in FIG.

The management server 1 is an AP server or a DB server, and collects inspection results from a plurality of mobile terminals 3 via communication lines and performs processing including aggregation processing. The management server 1 database includes an equipment management table 11 , an inspection result table 13, a totaling result table 15, a totaling condition / threshold definition table 16, and a required equipment condition table 18 requiring confirmation, which are the basis of the inspection equipment ledger file 12. Stored.

  The deterioration tendency totaling means 14 of the management server 1 uses the totaling condition definitions registered by the totaling condition / threshold definition registration means 21 of the administrator PC 2 for the inspection results collected from the plurality of mobile terminals 3 and stored in the inspection result table 13. And the defect occurrence rate in the total condition definition is calculated. The aggregation results by the deterioration tendency aggregation means 14 are stored in the aggregation result table 15.

  Further, the threshold determination means 17 compares the failure occurrence rate in the aggregation condition definition calculated by the deterioration tendency aggregation means 14 with the threshold registered by the aggregation condition / threshold definition registration means 21, and if the threshold is exceeded, The total condition definition is registered in the required equipment condition table 18 as the required equipment condition.

  The administrator PC 2 assigns an aggregation condition definition that defines the items and contents of the aggregation conditions used for the aggregation processing by the deterioration tendency aggregation means 14 of the management server 1, and a threshold definition of the defect occurrence rate in the aggregation condition definition. Has an aggregation condition / threshold definition registration means 21 for registering online. The administrator can change the aggregation condition definition and the threshold definition at any time from the aggregation condition / threshold definition registration means 21. The aggregation condition / threshold definition registration means 21 will be described later in detail with reference to FIG. The administrator PC 2 and the management server 1 are connected to be communicable with each other via a communication line such as a normal wired network (intranet).

  A plurality of handy terminals, PDAs (Personal Digital Assistants), and the like are prepared as the mobile terminals 3 that an inspector possesses during facility inspection work and inputs inspection results. The mobile terminal 3 includes an inspection application 31 having a download processing means for downloading the inspection equipment ledger file 32 from the management server 1 and a display means for displaying information necessary for inspection based on the inspection equipment ledger file 32 (see FIG. 6). And an input means (not shown) for inputting the inspection result. The inspection result is stored in the inspection result file 33 and uploaded to the inspection result table 13 of the management server 1.

  Further, the inspection application 31 displays an alarm message display means for displaying, on the display means, a warning message 34 informing that the inspection equipment is a facility requiring confirmation when the inspector inspects the inspection equipment corresponding to the equipment requirement requiring confirmation. (Not shown). The mobile terminal 3 and the management server 1 are connected to each other via a communication line such as a public line (VPN dedicated line).

In the present system configured as described above, when the inspector starts the facility inspection work, when the inspection application 31 of the mobile terminal 3 starts the download process of the inspection facility ledger file 32, the management server 1 displays the database. The inspection equipment corresponding to the required equipment conditions registered in the required equipment condition table 18 is extracted from the inspection equipment of the day included in the equipment management table 11 stored in the equipment management table 11 . Further, an inspection facility ledger file 12 to which identification information for identifying that the extracted inspection facility is a facility to be confirmed is added and downloaded to the mobile terminal 3. In the first embodiment, the inspection facility ledger file 12 is created in which the required facility flag is set as the identification information.

  Next, the flow of equipment inspection work and inspection result aggregation / analysis processing in this system will be described. The administrator registers the item of the total condition of the inspection result, its contents (total condition definition), and the threshold definition by the total condition / threshold definition registration means 21 of the administrator PC 2. FIG. 2 shows an example of a totaling condition / threshold definition registration screen (Web screen) displayed on the administrator PC 2. The administrator can register or update the aggregation condition definition and the threshold definition in real time on the aggregation condition / threshold definition registration screen 210 of the administrator PC 2 at any time.

  In the example illustrated in FIG. 2, the aggregation condition / threshold definition registration screen 210 selects an equipment setting area 221 for selecting an inspection target facility, and attribute items such as a manufacturing company, a district, and a facility company as the aggregation condition (individual) of the facility. An attribute item area 222, an attribute selection area 223 for designating a specific range of the attribute item selected in the attribute item area 222, an attribute item area 224 for selecting an attribute item of a totaling condition (band) such as a manufacturing year of equipment, and the like. It has an attribute selection area 225 for specifying the range, and a threshold setting area 226 for setting a threshold for the defect occurrence rate calculated under the aggregation conditions registered in each area.

  Note that items that are candidates for selection in the areas 221 to 225 and their contents (options, ranges, etc.) are all set in the item definition table 22. The item definition table 22 is collectively managed in the database of the management server 1, and attribute items and contents of all inspection facilities are registered.

  The aggregation condition / threshold definition registered from the aggregation condition / threshold definition registration screen 210 is uploaded to the aggregation condition / threshold definition table 16 of the management server 1, the deterioration tendency aggregation processing by the deterioration tendency aggregation means 14, and the threshold determination means 17. It is used in the threshold value determination process.

  Normal facility inspection work is regularly performed by a plurality of inspectors using a plurality of mobile terminals 3. When the inspector starts the inspection, the inspection application 31 provided in the mobile terminal 3 is activated, and the inspection equipment ledger file 32 necessary for the inspection on the day is downloaded. Thereafter, the inspector goes to the site, performs the inspection according to the inspection application 31, and the result is recorded in the inspection result file 33. After the inspection is completed, the updated inspection result file 33 is uploaded to the inspection result table 13 of the management server 1.

  As a result, the inspection result table 13 of the management server 1 stores the inspection results of all the facilities that have been inspected, for example, an enormous amount of about tens of thousands. In this system, the deterioration tendency totaling means 14 collectively performs a tabulation process (batch process) on all inspection results including past inspection results (history) accumulated in the inspection result table 13. The aggregation process by the deterioration tendency aggregation means 14 is set to be performed automatically at a predetermined frequency, for example, once a day at night.

  The flow of the deterioration tendency totaling process by the deterioration tendency totaling means 14 will be described using the flowchart of FIG. In FIG. 3, the numbers starting with S indicate the processing order (steps). First, in step 1 (S1), an inspection result is read from the inspection result table 13. Subsequently, in step 2 (S2), the aggregation condition definition is read from the aggregation condition / threshold definition table 16.

Next, in step 3 (S3), deterioration tendency totaling processing is performed based on the inspection results read in S1 and S2 and the totaling condition definition. Specifically, the number of defects occurring with the inspection facility corresponding to the total condition definition as a parameter is totaled, and the defect occurrence rate in the total condition definition is calculated. Thereafter, in step 4 (S4), the summation result of S3 is registered in the summation result table 15, and the process ends.

  After the deterioration tendency totaling process by the deterioration tendency totaling means 14 is completed, the threshold value determining process by the threshold value determining means 17 is performed. Note that the threshold value determination process is automatically performed at a predetermined frequency in a batch process, as in the deterioration tendency aggregation process. For example, it is set to be performed once a day at night.

  The flow of the threshold determination process by the threshold determination means 17 will be described using the flowchart of FIG. First, in step 11 (S11), the aggregation result by the deterioration tendency aggregation means 14 is read from the aggregation result table 15. The aggregation result is a failure occurrence rate in the aggregation condition definition registered by the administrator. Subsequently, in step 12 (S12), the threshold definition in the aggregation condition definition of the aggregation result is read from the aggregation condition / threshold definition table 16.

  Next, in step 13 (S13), a threshold determination process is performed in which the tabulation result read in S11 is taken out and compared with the threshold read in S12. In step 14 (S14), if the failure occurrence rate of the total result exceeds the threshold value, the process proceeds to step 15 (S15), and the total condition definition is registered in the required equipment condition table 18 as the required equipment condition. To do. If the threshold value is not exceeded in S14, the processing is terminated as it is.

  As described above, when the deterioration tendency aggregation process (FIG. 3) and the threshold determination process (FIG. 4) are completed, the aggregation condition definition in which the defect occurrence rate exceeds the threshold is registered as the required equipment condition. For example, XX equipment manufactured from XX year to XX year or XX equipment installed in XX area by Company A from XX year to XX year It ’s like that. Equipment that meets this required equipment condition is equipment that has a possibility of malfunction (high probability) and should be inspected with priority.

  Next, the flow of processing for downloading from the management server 1 the inspection equipment ledger file 32 used by the inspector for the day's inspection work will be described with reference to the flowchart of FIG. The inspector starts download processing from the inspection application 31 of the mobile terminal 3. Thereby, in step 21 (S21), the management server 1 reads the inspection equipment ledger file 12 for the day inspection from its own database.

  Subsequently, in step 22 (S22), the management server 1 reads the required equipment condition from the required equipment condition table 18. Furthermore, in step 23 (S23), it is determined whether or not each facility registered in the inspection facility ledger file 12 acquired in S21 matches the required facility condition acquired in S22. If they match in S23 (Yes), it is determined that the facility is a required facility, and in step 24 (S24), a required facility target flag is registered. If not matched in S23, the process is terminated.

  The processing after S23 is performed on all facilities for the day inspection registered in the inspection facility ledger 12, and the inspection facility corresponding to the required facility condition is extracted. Thereafter, an inspection facility ledger file 12 in which a flag is set for a facility to be confirmed is created and downloaded to the mobile terminal 3.

FIG. 6 is a diagram showing a screen image of the mobile terminal 3. The inspector downloads the inspection facility ledger file 321 in which the facilities to be confirmed are flagged by the inspection application 31 of the mobile terminal 3. Thereafter, when the inspector inputs the equipment to be inspected from the display screen 35 of the mobile terminal 3, the inspection application 31 refers to the item of the required equipment flag in the inspection equipment ledger file 321, and whether or not the equipment is the required equipment. To check. If the required equipment flag is set for the equipment, a warning message 311 is displayed to inform the inspector that the equipment is required.

  As described above, according to the facility inspection work support system according to the first embodiment, the management server 1 includes the deterioration tendency totaling unit 14 and the threshold value determining unit 17, and the totaling condition definition and threshold value registered by the administrator PC 2. Based on the definition, the defect occurrence rate in the aggregation condition definition is calculated, and when the failure occurrence rate in the aggregation condition definition exceeds a threshold, the aggregation condition definition is registered as a facility condition to be confirmed and downloaded to the mobile terminal 3 Since the flag is set for the required equipment in the inspection equipment ledger file 32 to be checked, the inspector can focus on the required equipment having a high probability of occurrence of a failure.

  Thereby, it is possible to prevent human errors such as oversight of troubles in facilities requiring confirmation and to prevent occurrence of accidents. Further, the inspection application 31 of the mobile terminal 3 refers to the flag of the inspection equipment ledger file 32 and displays a warning message 34 when the inspector inspects the equipment requiring confirmation. It is possible to notify that it is a facility requiring confirmation, and the quality of inspection work can be improved.

  In addition, the processing by the deterioration tendency totaling means 14 and the threshold value determining means 17 is automatically performed at a predetermined frequency (once a day in the first embodiment, at night), so that the inspection results can be quickly totaled and analyzed. It can be performed and can be reflected in timely inspection work from the next time.

  Furthermore, the administrator can change the aggregation condition definition and the threshold definition online at any time by the aggregation condition / threshold definition registration means 21 of the administrator PC 2 and stored in the database of the management server 1 at that time. Since the aggregation conditions can be defined from a flexible and free viewpoint for all attribute information set in the item definition table 22, the quality of the aggregation and analysis work can be improved.
