In addition, an IC tag communication function 119 which is a camera function 118 and a communication function with an external medium is provided.

  Here, the procedure of on-site inspection using the on-site inspection system according to the present invention will be briefly described. First, the worker (inspector) 121 makes a request for downloading an inspection plan to the on-site inspection management device 1 using the mobile terminal 2. Upon receiving the inspection plan download request, the on-site inspection management device 1 generates an inspection plan 111 by the mobile terminal communication processing 110 based on the inspection item management information 103. The worker 121 downloads the generated inspection plan 111 to the portable terminal 2 and then carries the portable terminal 2 to perform an on-site inspection. The inspection result is input from the inspection data input screen 116 at the inspection site and stored in the inspection result data 115. After the inspection is completed, the worker 121 requests uploading of the inspection result data 115 to the site inspection management device 1. The site inspection management device 1 that has received the upload request stores the inspection result data 115 in the inspection result information 104 by the mobile terminal communication processing 110.

  Conventionally, the worker 121 has performed an on-site inspection while confirming the inspection data input screen 116 that is created based on the inspection plan 111 downloaded to the mobile terminal 2 and displays the inspection items in the order of the inspection route. However, if the operator is unfamiliar with the on-site inspection work, such as not knowing the inspection place and inspection location by simply displaying the inspection items in the order of inspection route on the inspection data input screen 116, the cause of inspection omission and inspection error It was.

  In the field inspection system according to the present invention, a map information (two-dimensional) file 106, a map information (three-dimensional) file 107, and an inspection point file 108 are provided in the field inspection management apparatus 1, and the inspection place is linked to the inspection item management information 103. And by making the inspection location clear and displaying it on the portable terminal 2, the operator 121 can be correctly inspected. The map information (two-dimensional) file 106 and the map information (three-dimensional) file 107 are electronic information such as factory site drawings, aerial photographs, design drawings of each building, or floor diagrams created independently. And 3D map information. The inspection location file 108 is electronic information such as an electronic file obtained by taking a photograph of the facility to be inspected, or an inspection location designation diagram that is uniquely created and clarifies the inspection location. The map information (two-dimensional) file 106, the map information (three-dimensional) file 107, and the inspection location file 108 are registered in the field inspection management apparatus 1 in advance.

  The inspection location and the inspection location are registered on the site inspection management screen 105 of the site inspection management device 1. The inspection location is registered by displaying the map information (two-dimensional) file 106 or the map information (three-dimensional) file 107 on the site inspection management screen 105 and specifying the inspection location on the screen with a pointing device or the like. The coordinates of the inspection place are acquired and stored in the inspection item management information 103. The inspection location is registered by marking the electronic location of the inspection location file 108 by marking the inspection location or reading electronic information such as an inspection location designation diagram, and storing this designation information in the inspection item management information 103.

  When the operator 121 downloads the inspection plan 111 to the mobile terminal 2 by registering the inspection location and the inspection location, the mobile terminal communication processing 110 includes the map information (two-dimensional) file 106, the map information (3 Dimension) file 107 and inspection location file 108 are referred to, and map information data (2D) 112, map information data (3D) 113, and inspection location data 114 are generated. Map information data (2D) 112, map information data (3D) 113, and inspection location data 114 are stored in map information (2D) file 106, map information (3D) file 107, and inspection location file 108, respectively. The corresponding data for the portable terminal 2 is downloaded to the portable terminal 2 together with the inspection plan 111.

  When the map information data (two-dimensional) 112 and the map information data (three-dimensional) 113 are displayed on the inspection data input screen 116 of the mobile terminal 2, the map information data (two-dimensional) 112 is registered on the on-site inspection management screen 105 and the inspection item management information 103. The inspection location is marked with a marker based on the coordinates of the inspection location stored in. Thereby, the portable terminal 2 can identify and display an inspection place.

  In addition, the inspection location data 114 is stored in the inspection location based on the designation information registered in the on-site inspection management screen 105 and stored in the inspection item management information 103 when displayed on the inspection data input screen 116 of the portable terminal 2. Marked with a marker. Thereby, the portable terminal 2 can identify and display an inspection location.

  The operator 121 displays the inspection location / inspection location image screen 122 indicating the map information indicating the inspection location and the inspection location on the inspection data input screen 116 while confirming the inspection location, the inspection route, and the inspection location. Inspection work can be performed. The inspection location / inspection location image screen 122 is displayed based on each data of the inspection data 102.

  From the on-site inspection management screen 105, in addition to image information (map information) indicating the inspection location and inspection location, the inspection location and inspection location can be registered in the inspection item management information 103 as character information. This character information is registered in advance in the inspection item management information 103 as a location comment or an inspection location comment. The registered character information is included in the inspection plan 111 and downloaded to the portable terminal 2. The downloaded character information can be arbitrarily displayed by the operator 121 as an inspection location / inspection location guidance screen 123, and a more reliable inspection operation is possible.

  FIG. 3 shows an example of the screen display of the mobile terminal 2. FIG. 3 shows an example of an inspection location / inspection location image screen 122 and an inspection location / inspection location guidance screen 123 displayed on the inspection data input screen 116 of the mobile terminal 2.

  Map information data (two-dimensional) 112 is displayed on the inspection location / inspection location image screen 122a. In this example, a plurality of pumps 10 are displayed on the inspection location / inspection location image screen 122 a, but the inspection location marker 11 is attached to the pump to be inspected based on the inspection item management information 103. The operator 121 can specify that the pump 10 to which the inspection place marker 11 is attached is an inspection place. In addition, text information can be displayed as the inspection location / inspection location guidance screen 123a. The character information displayed on the inspection location / inspection location guidance screen 123 a is a location comment registered as character information in the inspection item management information 103.

  The inspection location / inspection location image screen 122b is an example in which map information data (three-dimensional) 113 is displayed. Similar to the inspection location / inspection location image screen 122 a, a plurality of pumps 10 are displayed on the inspection location / inspection location image screen 122 b, and the pump 10 with the inspection location marker 11 attached based on the inspection item management information 103. Is the inspection place. In addition, text information can be displayed as the inspection location / inspection location guidance screen 123b. As described above, in the field inspection system according to the present invention, by displaying the three-dimensional map information, the inspection place is displayed more accurately, and the inspection place is clarified even for an unfamiliar operator (inspector). It is possible.

  Inspection location data 114 is displayed on the inspection location / inspection location image screen 122c. In this example, the pump 10 to be inspected is displayed on the inspection location / inspection location image screen 122 c, but the inspection location marker 12 is attached to the inspection location of the pump 10 based on the inspection item management information 103. The operator 121 can specify that the location with the inspection location marker 12 is the inspection location. In addition, text information can be displayed as the inspection location / inspection location guidance screen 123c. The character information displayed on the inspection location / inspection location guidance screen 123 c is an inspection location comment registered as character information in the inspection item management information 103.

  Further, on the inspection data input screen 116, inspection items that have been inspected can be marked and displayed. In the example shown in FIG. 3, the inspection data input screen 116 is marked with a black circle 13 and a white circle 14. The black circle 13 is a mark when the inspection result is abnormal, and the white circle 14 is a mark when the inspection result is normal. As described above, when the inspection data input screen 116 is used, it is possible to grasp the inspection items that have been inspected and the inspection results.

  In the field inspection system, the system is often constructed by using a small mobile terminal because of the portability at the time of the field inspection work, but the mobile terminal breaks down due to dropping or submerging during movement or inspection work. There are many examples. In the conventional field inspection system, a dedicated application such as the inspection data input screen 116 is installed and used on the mobile terminal. For this reason, every time a portable terminal breaks down, it is necessary to install an application, and time and know-how are required for recovery.

  In the field inspection system according to the present invention, the mobile terminal 2 uses a general Web browser instead of a dedicated application. In other words, a web browser is used as the inspection data input screen 116 and the like, and the necessary information is downloaded from the site inspection management device 1 to the portable terminal 2. For this reason, even if the portable terminal 2 breaks down, it can be restored simply by setting the Web browser of the portable terminal 2, and the maintainability can be improved.

  When a failure of the inspection target equipment is found during the on-site inspection, it is possible to take a note or input a comment to the inspection data input screen 116 of the portable terminal 2 and record it as character information. This character information is stored as a comment in the inspection result information 104 of the database 101 of the site inspection management device 1 when the inspection result data 115 is uploaded. However, it is often difficult to accurately represent the state of the facility to be inspected (such as the degree of failure) using character information.

  Therefore, in the field inspection system according to the present invention, an on-site photographed image file 117 can be generated by photographing an on-site image using the camera function 118 provided in the portable terminal 2. An on-site image can be taken by pointing the shooting button 201 of the camera displayed on the inspection location / inspection location guidance screen 123c shown in FIG. 3 with a pointing device or the like. The on-site photographed image file 117 which is photographed image data is stored as the on-site photographed image file 109 in the on-site inspection management apparatus 1 when the inspection result data 115 is uploaded. By displaying the on-site photographed image file 109 on the on-site inspection management screen 105, it is possible to represent accurate information on the inspection target equipment that cannot be conveyed only by text information with the photographed image.

  In the field inspection system according to the present invention, when an external medium is attached to the facility to be inspected, information recorded on the external medium can be read using a communication function with the external medium included in the mobile terminal 2. In the example illustrated in FIG. 2, the IC tag 120 is used as an external medium, and the mobile terminal 2 can read information recorded on the IC tag 120 using the IC tag communication function 119. By collating the information read by the portable terminal 2 with the inspection plan 111, it is possible to prevent mistakes in the inspection target equipment. In addition, when entering the inspection result on the inspection data input screen 116, it is possible to display the previous result as the previous value at the next inspection by writing the inspection result to the IC tag 120 attached to the inspection target equipment. It becomes. By comparing the data and state at the time of inspection with the previous values on the spot, it is possible to grasp the situation as a time series of the equipment to be inspected.

  Note that another external medium such as a barcode may be used instead of the IC tag 120. In this case, the mobile terminal 2 has a communication function suitable for the used external medium instead of the IC tag communication function 119. Data cannot be written on a read-only external medium such as a barcode, but the recorded data can be read and used during inspection.

  In the on-site inspection system according to the present invention, the mobile terminal 2 can have a function of displaying only uninspected inspection target equipment. The inspection data input screen 116a shown in FIG. 3 is an example in which only inspection target equipment that has not been inspected is displayed. With this function, even if the number of facilities to be inspected is large, the worker 121 can easily grasp the facilities to be inspected from now on, and can prevent omission of inspection.

  When the inspection target equipment is abnormal (alarm is being transmitted) during the on-site inspection work, the worker 121 needs to grasp the inspection target equipment on the inspection data input screen 116 of the portable terminal 2. However, the inspection items displayed on the inspection data input screen 116 may exceed 1000 points, and it is difficult to easily find the inspection target equipment that is abnormal.

  In the field inspection system according to the present invention, as shown in FIG. 3, an alarm list guidance screen 124 that displays only the inspection target equipment that is abnormal (during alarm transmission) can be displayed on the inspection data input screen 116. The alarm list guidance screen 124 allows the worker 121 to check the alarms in a list.

  As described above, in the field inspection system according to the present invention, even when the operator does not know the inspection place or inspection location, the inspection location or inspection location can be grasped by referring to the image information or text information. On-site inspection can be performed. Further, inspections and inspection errors can be prevented by performing inspections while referring to image information and character information.
