  Further, the inspection information data 130 stored in the inspection information database 113 includes an apparatus name 131 of each device A,... N, an IC tag unique number 132 for identifying each device A,. , Inspection items 140, and device image files 135 in which, for example, data photographed by the mobile terminal 10 are set using the IC tag unique number 132 as a key to identify each device A,... N are stored. ing. The inspection item 140 stores an inspection item 133 and an inspection operation procedure 134 for the item 133. For example, as shown in FIG. 6, an item 133 to be performed for one inspection and an inspection operation procedure 134 for the item 133 are stored as associated information.

  Next, the operation of the inspection system of the first embodiment configured as described above will be described. First, the inspection information data 130 of the target device to be inspected necessary for inspection is downloaded from the synchronization interface 114 of the maintenance inspection data management server 20 to the storage unit 102 of the mobile terminal 10 by the data synchronization mechanism of the communication medium 15 ( Step S1) in FIG. Next, the inspection information data 130 is downloaded to the mobile terminal 10 and traveled to the site. The tag reader / writer 104 is held over any IC tag installed in front of the equipment, and the tag information 120 is read (see FIG. 7). Step S2). Next, in the control unit 100, whether there is an identical one with the IC tag unique number 121 of any read IC tag and the IC tag unique number 132 present in the inspection information data 130 stored in the storage unit 102 as a key It is determined whether or not (step S3 in FIG. 7). If the same IC tag unique number does not exist, an error display indicating that the corresponding device that has read the arbitrary IC tag is not the inspection target facility is displayed on the display unit 101 (step S10 in FIG. 7). The inspector reads new IC tag data and repeats the above operation.

  If the same IC tag unique number exists, the device image file 135 is displayed on the display unit 101 from the matched inspection information data 130 (step S4 in FIG. 7). Next, the data of the cursor position 122 in the device image of the IC tag information 120 is read from this device image (step S5 in FIG. 7). Based on the data of the cursor position 122 in the device image, the cursor is displayed on the device image as shown in FIG. 3, for example (step S6 in FIG. 7). Next, the inspector confirms the device and transmits a coincidence signal from the input unit 103 to the control unit 100 (step S7 in FIG. 7). Next, the control unit 100 accepts a coincidence signal (step S7 in FIG. 7). Next, the inspection item 140 in the inspection information data 130 is displayed on the display unit 101 as shown in FIG. 6, for example (step S7 in FIG. 7). Then, the inspector takes over the inspection procedure of the inspection item 140 and inspects the equipment confirmed by the equipment image.

  The inspection system according to the first embodiment configured as described above can be used even when there are a plurality of inspection points (for example, the front surface, the upper surface, the right side surface, the left side surface, or more detailed portions) in the facility or the same device. The inspection can be surely performed by the IC tag and the device image with the specified location. The inspection item of the device can be specified by not only the IC tag but also the position in the device image or the device image stored in the IC tag by displaying a cursor to check the device to be inspected. Especially in the installation of IC tags, depending on the installation status of the equipment, there are some equipment that can not be placed directly on the equipment (when it is in a protection area such as a wire mesh) or that cannot be placed directly on the equipment itself due to high temperature. When multiple devices are stored in the protected area, it is difficult to specify the device with the IC tag alone, and the position of the inspection device (cursor position) in the device image or IC tag in the image. By recording, it is possible to easily and reliably specify the target device for the inspector.

  In the first embodiment, the example in which the inspection item is displayed after confirming the coincidence signal obtained by confirming the device image by the inspector is shown. However, the present invention is not limited to this, and both the device image and the inspection item are displayed. It is also possible for the inspector to check and perform the inspection. In addition, although an IC tag is shown as an example of the tag, the present invention is not limited to this, and a tag such as a barcode can be similarly applied. The same applies to the following embodiments, and the description thereof will be omitted as appropriate.
