BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a failure countermeasure support system for mechanical equipment according to the present invention. FIG. 1 is a block diagram showing an apparatus in which a failure countermeasure support system of the present invention is applied to a crane, FIG. 2 is a configuration diagram showing information of a database of the embodiment, and FIG. 3 is one abnormality in the database of the embodiment. FIG. 4 is a diagram showing the configuration of a personal file in which security levels are set for each individual in the embodiment, and FIG. 5 is a flowchart showing the operation of the failure countermeasure support system in the embodiment. .

As shown in FIG. 1, a crane control device 1 and a failure countermeasure support device 2, which are objects of failure countermeasures, provide a failure abnormality code from the crane control device 1 when a failure occurs. It is configured to be transmitted to the device 2.

The failure countermeasure support device 2 includes a database 22 that specifies a security level for each related information such as a confirmation item and a recovery method via the central control unit 21 and a personal file in which the security level of each worker is registered. 23
And a console 24 for dialogue with an operator.

In such a configuration, when the failure countermeasure support device 2 receives an abnormal code from the control device 1, the failure countermeasure support information for the abnormal code shown in FIG.
To be displayed. The operator performs a failure cause investigation and a failure recovery operation while viewing the failure countermeasure support information displayed on the console 24.

At this time, the failure countermeasure support device 2 reads the security level of the logged-in worker from the personal file shown in FIG. 4, and finds out the security level of the logged-in worker in the failure countermeasure support information shown in FIG. It has a function to display only failure countermeasure support information of the same or lower security level. The login and logout of the operator can be performed from the console 24 at any time. When logging in, enter your name and password. When no worker is logged in, the security level is treated as the lowest. At the end of the troubleshooting support, the logged-in worker is automatically logged out.

Next, the operation of the failure countermeasure support device 2 of FIG. 1 will be described with reference to the flowchart of FIG. 5 and FIGS. When the central control unit 21 of the failure countermeasure support device 2 receives an abnormal code from the crane control device 1 when a crane failure occurs, the central control unit 21 searches the database 22 and reads the first data of the failure countermeasure support information corresponding to the abnormal code. (Step S1). The worker at this time is not specified, and the security level is blank.

Next, the security level of the read data is confirmed (step S2). If the security level is "operator≥data", the process proceeds to the next step S3, where the data is displayed on the console 24 (step S2).
3). In this case, the security level of the personal file shown in FIG. 4 can be set in the console 24 with respect to the specialized field, the years of experience, and the technical level. Thus, the failure countermeasure can be supported by using the information corresponding to the security level of the worker, so that the failure countermeasure work can be performed safely based on the objective evaluation. In addition, in the case of a task that cannot be handled at the level of the worker being handled, the security level necessary for the countermeasure can be displayed and the support of a worker at a higher level can be obtained.

Next, the operator investigates the cause based on the failure countermeasure support information corresponding to the abnormal code displayed on the console 24 (step S4). Then, step S5
If the cause is known, the operator inputs the cause to the console 24 (step S6), and if the cause is not known, inputs no cause to the console 24 (step S13). When the identified cause is input in step S6, the data of the recovery method corresponding to the identified cause is read from the database 22 (step S6).
7). At this time, the security level of the worker is compared with the security level of the data (step S8), and if the security level is “worker ≧ data”, the data is displayed on the console 24 (step S9). The operator restores the failure by viewing the displayed data (step S10). When the failed part is recovered, the operator logs out (step S11), and the failure countermeasure support ends.

On the other hand, if the security level is "operator <data" in step S8, "login worker unavailable" is displayed on console 24 (step S1).
2) Log out (step S11) and end.

Further, if the cause is not determined in step S5, "no cause" is input to the console 24 (step S13), and the presence or absence of the next data is confirmed on the console 24 (step S14). If there is no next data, the process proceeds further (step S15), and it is confirmed whether or not there is data with the worker's security level of "worker <data" in the operation after step S2.
If there is data of “worker <data”, “login worker not available” is displayed (step S12), logout is performed (step S11), and the process ends. If there is no data of "operator <data", the user logs out as it is (step S11) and ends.

In step S14, the database 22 is checked. If there is data corresponding to the next abnormal code, new data is read from the database 22 (step S16), and the security level of the read data is checked again. (Step S2) If the security level is “operator ≧ data”, the process proceeds to step S3, and thereafter proceeds as described above.

If the security level is not "operator≥data" in step S2, the process proceeds to step S14, and the operation after step S14 is performed. That is, if there is no more data in the database 22 that the worker can cope with the abnormal code, the security level is searched again for data of "worker <data" (step S15). In the same manner as described above, “Unable to handle logged-in worker” is displayed (step S1).
2) Log out (step S11) and end. If there is no data of “operator <data”, log out as it is (step S11) and end.

As described above, the failure countermeasure support apparatus according to the embodiment of the present invention includes a database 22 in which a security level is designated for each failure-related information, a personal file 23 in which a security level is set for each individual, and And a central control unit 21 as selection means for selecting information to be displayed as a countermeasure for a worker among the fault-related information, and instructs a countermeasure work according to the level of the worker. In addition to the above, when a trouble countermeasure cannot be performed depending on the level of the worker, a worker at a higher level can cope with the trouble, whereby the trouble countermeasure support can be performed safely according to the level of the worker.

Further, the security level for each individual
By setting the field of expertise, years of experience, and technical level, the failure countermeasure support system can further ensure safety based on objective evaluation.

In the above, the failure countermeasure support device connected to the control device has been described in the embodiment, but the same effect can be obtained by a failure countermeasure support device not connected to the control device.
In this case, the same operation can be performed by inputting the abnormal code by the operator. Further, it is also possible to adopt a configuration in which a failure countermeasure support device is built in the control device.

[0024]

According to the failure countermeasure support system of the present invention, a database in which a security level is designated for each failure-related information and a personal file in which a security level is set for each individual are used. By selecting information to be displayed as a countermeasure for a worker from among the fault-related information, it is possible to instruct a trouble-shooting operation according to the level of the worker, and not to take a countermeasure according to the level of the worker. In this case, a worker at a higher level can deal with the trouble, and accordingly, failure countermeasure support can be performed safely according to the level of the worker.

Further, the security level of each individual
By setting the field of expertise, years of experience, and technical level, the failure countermeasure support system can further ensure safety based on objective evaluation.
