Prior to patrol of the equipment installed in the field of the plant, the patrol member selects a corresponding storage medium from a plurality of storage media prepared for each patrol route and mounts the storage medium 1 on the apparatus. . The patrol member carries a device such as a handy terminal and gives an instruction for displaying a patrol route from the keyboard 4. ) Is graphically displayed, for example, a route map. This is performed by the information reading means 2 reading related information from the storage medium 1.

FIG. 4 is a diagram showing points to be patroled first on the route map displayed on the display means 5 at this time. Here, an example is shown in which an entire map to be patroled or a map obtained by enlarging a part thereof is displayed, and a patrol point to be checked first is blinking displayed, for example. Also, at the bottom of the screen, an instruction for an operation to be performed when the patrol member reaches the inspection location, that is, an operation for reading patrol point information for identifying the inspection device attached to the device to be inspected, is provided. Is displayed. When the patrol member arrives at the patrol point, the patrol member, in accordance with the operation instruction (operation guide), obtains patrol point information for determining the inspection device attached to the device to be inspected, for example, a magnetic reader or a bar code reader. Read using Patrol point information reading means 3
Enter the patrol point information read via the reader, and check the patrol points to be checked displayed on the display means 5 and the patrol points read via the reader.
It is determined whether the ID code included in the point information matches, for example, the ID code. If the ID code matches, an inspection procedure to be inspected at the patrol point is displayed on the display unit 5. The information of the inspection procedure at the patrol point is read from the storage medium 1 and displayed. The display of the inspection procedure may be displayed by a window on a map indicating a patrol route, for example. From the display of the inspection procedure, the patrol member knows that the correct inspection location has been reached. Patrol points to check and ID included in patrol point information
If the code does not match, the patrol point will be different and a message will be displayed to reconfirm the patrol route.
