Description

The present invention relates to a device maintenance method and a device.

Generally, in plant equipment such as coal-fired power plants, for example, in the case of a belt conveyor that conveys coal, once the operation of a safety device or the like is detected, the operation of the belt conveyor is temporarily stopped to deal with the cause of the stop. After that, the operation of the belt conveyor is restarted.

Therefore, the electric motor used for the belt conveyor is repeatedly started, operated, stopped, and restarted, so that maintenance is particularly important.

Conventionally, in the case of various devices including the motor, a measuring instrument is brought to the site at the time of inspection or when a failure occurs, and measurement is performed by the measuring instrument.

At the time of inspection of the equipment, the measurement result by the measuring instrument is recorded and stored on a paper medium such as a recording paper.

Further, when a failure occurs in the device, the measurement result by the measuring instrument is used as a reference for identifying the failure location, and information on a similar situation is extracted from the history. At this time, the instruction manual or the like of the device may be confirmed and the countermeasure may be taken, or the manufacturer of the device may be contacted and the countermeasure may be confirmed and implemented.

For example, Patent Document 1 indicates a general technical level related to equipment maintenance.

For the countermeasure items and additional action items, a format is adopted in which a plurality of candidates are stored in advance in the failure countermeasure content input terminal 90, and the worker selects the countermeasure item and the additional action item from the candidates. However, it is also possible to adopt a format in which the worker manually inputs the countermeasure item and the additionally implemented item from the failure countermeasure content input terminal 90.

Next, the operation of the above embodiment will be described.

At the time of inspection of the device 10, for example, when the operator reads the IC tag attached to the device 10 by a terminal such as a tablet at the time of inspection, the inspection record creation signal 60 is input to the inspection record automatic creation unit 40a of the arithmetic unit 40. (Refer to the inspection record start process in step S10 of FIG. 2). The inspection record creation signal 60 may be periodically input from the controller 30 to the arithmetic unit 40 at the time of inspection.

Subsequently, the inspection record automatic creation unit 40a extracts the name data of the device 10 corresponding to the inspection record creation signal 60, the sensor data of the device 10 from the sensor 20, and the operation status data of the device 10 from the controller 30.

At least one detection value of vibration, temperature, and noise detected by the sensor 20 is the sensor data of the device 10. When the device 10 is an electric motor, the current may be included as the sensor data. Further, at least one of the operating time and the number of activations grasped by the controller 30 is included as the operating status data of the device 10.

After that, the inspection response contents carried out at the time of inspection without being extracted by the inspection record automatic creation unit 40a are input by the operator from the inspection response content input terminal 80 and stored in the database 40c (in step S30 of FIG. 2). Refer to the inspection response content input process). A plurality of candidates are stored in advance in the inspection response content input terminal 80 as inspection response content, and the operator selects and inputs the inspection response content carried out from among those candidates. However, the worker may manually input the contents of the inspection correspondence carried out from the inspection correspondence contents input terminal 80.

The recorded contents stored in the database 40c are displayed on the display 50 as needed.

On the other hand, when a failure occurs in the device 10, for example, a failure record creation signal 70 is automatically input from the controller 30 to the failure record automatic creation unit 40b of the arithmetic unit 40 (failure recording start step in step S100 of FIG. 2). reference). The operator may input the failure record creation signal 70 from a terminal such as a tablet to the failure record automatic creation unit 40b of the arithmetic unit 40.

Subsequently, in the failure record automatic creation unit 40b, the name data of the device 10 corresponding to the failure record creation signal 70, the sensor data of the device 10 from the sensor 20, and the operation status data of the device 10 from the controller 30. Is extracted and a failure record is automatically created and stored in the database 40c (see the failure record automatic creation step in step S110 of FIG. 2). As in the case of inspection, at least one detection value of vibration, temperature, and noise detected by the sensor 20 is the sensor data of the device 10. When the device 10 is an electric motor, the current may be included as the sensor data. Further, at least one of the operating time and the number of activations grasped by the controller 30 is included as the operating status data of the device 10.

Next, the current failure record automatically created by the failure record automatic creation unit 40b and stored in the database 40c and the past failure record stored in the database 40c are compared in the countermeasure item selection unit 40d. A degree of similarity is obtained, and a plurality of coping items corresponding to the failure records having a high degree of similarity are selected (see the coping item selection process in step S120 of FIG. 2).

A plurality of countermeasure items selected by the countermeasure item selection unit 40d of the arithmetic unit 40 are sequentially displayed on the display 50 in order from the one corresponding to the failure record having a high degree of similarity (see the display process in step S130 of FIG. 2). ).

The countermeasure items displayed on the display 50 are carried out by the operator and repeated until the countermeasure becomes effective (see the failure countermeasure step in step S140 of FIG. 2).

The countermeasure items and additional action items that have been implemented and contributed to the failure repair are input by the operator from the failure response content input terminal 90 and stored in the database 40c (see the failure response content input process in step S150 in FIG. 2). A plurality of candidates are stored in advance as countermeasure items and additional action items in the failure countermeasure content input terminal 90, and the operator selects and inputs the countermeasure item and the additionally implemented item from the candidates. .. However, the worker may manually input the countermeasure item and the additionally implemented item from the failure countermeasure content input terminal 90.

In the case of this embodiment, a measuring instrument is brought to the site during regular inspections or when a sudden failure occurs, measurement of many items is performed by the measuring instrument, and the measurement results are recorded and stored on a paper medium. There is no need to do this, and the burden on the worker is small.

Further, when a failure occurs, the complicated work of extracting information on a similar situation from the history is automatically performed inside the arithmetic unit 40, and the display 50 has a countermeasure item corresponding to a failure record having a high degree of similarity. Since it is displayed sequentially, it is possible to significantly reduce the time required for the restoration of the device 10.

Furthermore, by inputting the inspection response contents carried out at the time of inspection without being extracted by the inspection record automatic creation unit 40a from the inspection response content input terminal 80 and accumulating them in the database 40c, the subsequent inspection of the device 10 can be performed. It is effective for reference. In addition, by inputting the countermeasure items and additional action items that have been implemented and contributed to the failure repair from the failure countermeasure content input terminal 90 and accumulating them in the database 40c, it is effective in expanding the range of countermeasures when a failure occurs in the device 10. It becomes.

In this way, it is possible to automatically create necessary records at the time of inspection or when a failure occurs to reduce the burden on the operator, and it is possible to display countermeasure items when a failure occurs and efficiently perform recovery work.

It should be noted that the device maintenance method and the device of the present invention are not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
