(Operational principle of the embodiment)
Hereinafter, the operation principle in the field maintenance support system 10 according to the present embodiment will be described with reference to FIG.

  First, when an on-site inspection of the factory 1 is started by an inspector, the portable terminal device 30 and the on-site maintenance support device 20 possessed by the inspector are activated. Thereby, the field maintenance support system 10 is started. When the mobile terminal device 30 is activated, the arithmetic processing unit 34 reads and executes the on-site maintenance program 35a stored in the storage unit 35. When the field maintenance support device 20 is activated, the arithmetic processing unit 25 reads and executes the field maintenance support program 26a stored in the storage unit 26. Thereby, in the portable terminal device 30 possessed by the inspector, transmission / reception settings are made among the IC tag 40, the wireless sensor 50, and the field maintenance support device 20 added to the device to be inspected in the factory 1 ( Step S01), reception of signals from the IC tag 40 and the wireless sensor 50, transmission of signals to the IC tag 40, and transmission / reception of signals to / from the mobile terminal device 30 are possible.

  In the present embodiment, the IC tag 40 is added to equipment in the factory to be inspected. The IC tag 40 is input with IC tag information of the inspection importance level for the device to which the IC tag is attached and setting information as to whether or not alert information is transmitted so as to inspect the device. . The IC tag information is updated as appropriate by the inspector. The wireless sensor 50 does not need to constantly monitor the operation state, but is attached to a device that needs to be monitored based on a specific rule. The wireless sensor 50 can change the target device as appropriate, and the cost required for measurement is low. For this reason, the cost reduction required for the configuration, operation, and maintenance of the present embodiment is realized by using it as a configuration requirement of the present embodiment.

During inspection of the factory 1 by an inspector, when an abnormality is found in the equipment installed outside the inspection route and the inspection route, or from the IC tag 40 attached to the equipment installed outside the inspection route and the inspection route When the alert information is received by the mobile terminal device 30 (step S02), if the abnormality can be dealt with on the spot, the coping process is immediately implemented (step S06). However, if the handling process is unknown to the inspector, “notice item information” regarding the abnormality is input to the input unit 31 of the mobile terminal device 30 (step S03). Here, the “aware matter information” is information including, as a keyword, a language indicating a physical operation state recognized as an abnormality of a device in which an abnormality is found or a device to which an IC tag 40 that transmits alert information is added. It is.

“Awareness information” input to the mobile terminal device 30 is transmitted to the field maintenance support apparatus 20 via the communication unit 33 and the antenna unit 33a. The field maintenance support device 20 receives “awareness information” via the antenna unit 24 a and the communication unit 24. Based on this reception, the “aware matter information” is collated with the maintenance history information in the maintenance information DB 200 c stored in the in-factory maintenance information database 200. In the verification, a maintenance history is recorded using a language indicating a physical operation state that is recognized as an abnormality of a device with an IC tag to which an abnormality is included in “Awareness information” or that transmits alert information as a keyword. An abnormality equivalent to the abnormality included in the information is collated, and a maintenance method applied to the abnormality is searched. When maintenance information corresponding to the abnormality is not found in the maintenance information DB 200c stored in the in-factory maintenance information database 200, the maintenance history information in the maintenance information DB 300c stored in the remote monitoring center 2 is further checked. Done. And if the coping method corresponding to the said abnormality is searched, it will respond to the said abnormality based on the said keyword also from image information DB200d, operation information DB200a, and operation information DB200b which are stored in the database management apparatus 200 in a factory. Related information is retrieved and derived (step S04). FIG. 6 shows a description example of an operation diary in which maintenance items are noted in the maintenance information DB 200c and noticed by the inspector at that time, and how to deal with them, etc. Yes. The degree of importance of the abnormality of the target device described in this diary is an example of the maintenance history information. The inspection importance level input to the IC tag attached to the target device and the target device are inspected. In this way, the setting information indicating whether or not to transmit the alert information is used. FIG. 7 also shows which information stored in the other DB is related to the abnormality in the driving diary. When the inspector receives notification of the search end on the display unit 32 of the mobile terminal device 30, the inspector presses the display button set in the input unit 31 and relates to the abnormality shown in FIG. Maintenance history information necessary to deal with the abnormality, such as an operation log, can be displayed on the display unit 32 (step S05). Based on the maintenance history information, the inspector performs an optimum process for dealing with the abnormality (step S06).

After coping with the abnormality, the inspector inputs the content of the abnormality and a coping method thereof from the input unit 31 of the mobile terminal device 30 in order to make the information of the abnormality and the coping method common. The data is transmitted to the database of the factory database management apparatus 200 (step S07). Furthermore, the inspector adds an IC tag that is attached to a device in which an abnormality is recognized and transmits alert information from the input unit 31 of the mobile terminal device 30 based on a coping method and a coping result corresponding to the abnormality. In 40, information indicating the importance of inspection for the next inspection and the necessity of sending alert information is input. Thereby, the information of the IC tag 40 is updated. When the IC tag 40 is not added to the device corresponding to the abnormality and alert information, the new IC tag 40 is newly added to the device, and the new IC tag 40 is added to the input unit 31 of the mobile terminal device 30. The registration number, the inspection importance for the next inspection corresponding to the device to which the new IC tag is added, and information indicating whether or not the alerting information needs to be sent are input (step S08).

On the other hand, when an inspector approaches a device to which the wireless sensor 50 is attached during patrol, the measured value data of the device is automatically received by the portable terminal device 30 possessed by the inspector. The received measurement value data is displayed on the display unit 32 of the portable terminal device 30 and transmitted to the field maintenance support device 20 (step S10). The inspector confirms whether or not there is an abnormality in the operation of the device based on the measured value displayed on the display unit 32 (step S11). In this confirmation, if an abnormality is confirmed, but the coping method corresponding to the abnormality is not known, the “notice item information” shown in step S03 is input, and the coping method for coping with the abnormality is a mobile phone. The field maintenance support device 20 is inquired via the terminal device 30, and the steps after step S04 are executed.

  When the inspector circulates the inspection route and the on-site inspection is completed, the on-site maintenance support device 20 is described in the manual based on the inspection importance of each IC tag 40 transmitted from the mobile terminal device 30. The next inspection route based on the basic inspection route is created, and the inspection route information in the factory operation information database 200b is updated (step S09).

As explained above, the field maintenance support system 10 of the present invention allows
(1) The inspector recognizes an abnormality of the device during the patrol inspection of the plant, and inputs “aware matter information” to the portable terminal device 30 when the coping method for the abnormality is unknown. Based on the “Awareness information”, search the maintenance information DB 200c for data corresponding to past similar models and similar awareness information, and display the operation data, maintenance method and coping method at that time on the mobile terminal device 30. To do. As a result, even inexperienced inspectors can take appropriate measures. Further, more accurate information can be obtained by utilizing the plant maintenance information DB 300c in another factory. Furthermore, when the notice information is input with this system, similar notices and accidents in the past are immediately retrieved and displayed from the maintenance information DB 200c, so it is possible to recognize the inspection items requiring attention for inspection and maintenance. And prevent similar accidents.

(2) Further, in the present embodiment, “noticeable matter information” is stored in the database of the on-site maintenance support device 20 from the portable terminal device 30 possessed by the inspector and is used as data shared by all the inspectors. Therefore, by browsing it, it is possible to take an appropriate response even when an abnormal state that the user has not dealt with before is found. Then, by electronically inputting the corresponding method and result at that time to the mobile terminal device 30, the shared information in the database can be increased. In particular, the operation method in the event of an abnormality may be misrecognized as an individual or the entire plant, but browse and use other inspectors' coping methods and other plant's inspector's inspection and coping methods. As a result, it is possible to improve inspection skills and equalize skills not only within the factory but also between the factories. It works effectively to improve the skills of young inspectors.

(3) Further, in the present embodiment, in the inspection according to the inspection manual, the inspection is performed only at a time interval determined by a predetermined route, and the importance thereof is changed only when the inspection manual is revised. In the information transmission function using the IC tag 40 according to this embodiment, the inspector approaches the IC tag 40, automatically reads the IC tag information input by the inspector in the past, and the importance of the information is high ( The importance can be input by the inspector in the past), it can be inspected again and the inspection result can be input, and the inspection route can be optimized at the level of the inspector who knows the situation in detail. As a result, appropriate inspection and maintenance are carried out in the plant to be managed, and the safety of the plant is improved.

(4) Moreover, in this embodiment, in order to grasp the operation status of important equipment, the sensor attached to the equipment is connected to the central operation room that manages the equipment in the factory by wired wiring. Although it is constantly monitored, equipment such as boiler feed pumps and secondary air fans are only equipped with simple on-site instruments such as current values. Yes. In the present embodiment, in order to reduce the inspection cost, a small and inexpensive wireless sensor 50 is attached in place of the field instrument, and the inspector with the portable terminal device 30 automatically vibrates, temperature, and sound during the patrol. By collecting data such as the above and automatically analyzing the abnormality of the equipment, the inspection costs are reduced by the inspector and assistance for early detection of abnormal signs. And reduction of plant operation and maintenance costs is realized.
