Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance monitoring system, and more particularly, to a maintenance management system capable of improving efficiency of maintenance inspection and parts management.

[0002]

2. Description of the Related Art Equipment such as cranes, chillers, and gas turbines are not mass-produced goods, unlike general consumer goods. Even if there is a basic design, it is general that it is individually designed according to the customer's request. Therefore, there are not only general-purpose parts but also many dedicated parts, and not only parts that can be immediately procured. Also, since the number of parts is large, parts management is difficult.

[0003] The above equipment is used professionally and has a high operating rate. Therefore, such equipment is generally subjected to periodic inspections. In order to perform regular inspections, the downtime of the equipment must be minimized, service personnel must be arranged, and maintenance parts must be prepared. In the past, the current situation was to rely on humans to determine when periodic inspections should be performed.
For this reason, there have been cases where leakage has occurred in preparation for maintenance and inspection.

[0004] For this reason, if there is an omission of ordering of a maintenance part, the use suspension time of the equipment for procurement of the maintenance part becomes long. In addition, since it is difficult to manage data indicating how many parts are in stock on the user side of the device, an extra order for maintenance parts has been sometimes made. However, in this case, unnecessary inventory is kept, and the running cost of the equipment increases. In addition, it is necessary to consider deterioration over time until the component is used.

Further, when a failure occurs, even if the location of the failure can be specified, repair cannot be performed without maintenance parts. Therefore, there is no problem if the customer has all the maintenance parts, but preparing all the maintenance parts increases the running cost of the equipment. Further, when a failure occurs in a separately designed mechanism, it is difficult to procure the parts. However, the parts may be located elsewhere. In such a case, if parts are interchanged, the inventory of maintenance parts can be reduced. As a result, running costs can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A maintenance management system according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the overall configuration of the maintenance management system according to the first embodiment of the present invention. Referring to FIG. 1, the maintenance management system includes a user A side 2-
1 and a device provided on the user B side 2-2, and a center device 4 provided commonly to the users.

The user A side 2-1 has a device (1) 6-1.
And the device (2) 6-2 are installed, and the monitoring devices 10-1 and 10-2 are provided for each device. A device (11) 8-1 is installed on the user B side 2-2, and a monitoring device 10-11 is provided for the device (11) 8-1. In this example, the customer equipments 6-1, 6-2, and 8-1 are port cranes. Monitoring devices 10-1, 10-2, 10
-11 is used to control the operation of the corresponding crane (equipment) in addition to the functions of the present invention described below. The monitoring devices 10-1, 10-2, and 10-11
Have the same configuration, the monitoring device 10-1
Only the following will be described.

The monitoring device 10-1 has a control unit 12, a communication unit 14, a storage unit 16, an input unit 18, and a display unit 20. The storage unit 16 stores operation data 16-2, a parts inventory list 16-4, and an operation schedule table 16-6.

The operation data 16-2, as shown in FIG. 2, indicates the operation results for each component constituting the device (1) 6-1. As shown in FIG. 3, the parts inventory list 16-4 indicates the inventory status of each of the parts constituting the device (1) 6-1. The operation schedule table 16-6 shows the work schedule of the device. FIG. 4 shows a work schedule of the device (1), and FIG. 5 shows a work schedule of the device (2) created by the monitoring device 10-2.

The center device 4 includes a control unit 30 and a communication unit 3
2, a storage unit 34, an input unit 36, and a display unit 38. The storage unit 34 stores the entire operation data 34-2, the entire parts inventory list 34-4, the operation schedule table 34-6, and the maintenance reference list 3
4-8, Schedule of personnel 34-10, Schedule of maintenance and inspection 34-
12 is stored.

As shown in FIG. 6, the overall operation data 34-2 indicates the operation results for each user, each device, and each component. The overall operation data 34-2 has fields of device name, component name, integrated operation data, average operation rate, and remaining life. An identifier is assigned to each user's device for each user and each device.

The integrated operation data is updated based on the operation data 16-2 obtained from the monitoring device 10-1. Therefore, the integrated operation data indicates the operation status of the component parts up to the present. Therefore, this data is reset to 0 when the component is replaced. The average operation rate indicates an average operation state per day. In this example, one day is used as a reference, but time or a week, month, or year may be used as a reference. The remaining life indicates the remaining life of the component. Therefore, if the remaining life is divided by the average operation rate, the number of days until component replacement can be calculated.

The entire parts inventory list 34-4 shows the inventory status of the components for each user as shown in FIG. The whole parts stock list 34-4 includes fields of a user name, a part name, a stock quantity, an appropriate stock level, and a manufacturer ID.

A user name is written in the user name.
The used component is written in the component name. The same part name is not written in the same user. The stock quantity indicates the total stock quantity of parts stored on the user side. The appropriate stock level indicates the appropriate stock level in the current operation status. For example, the device (1) has 10 A-type switches.
Once all of the A-type switches have been replaced, inventory of the A-type switches should not be necessary. However, considering the occurrence of sudden failure, for example,
The appropriate stock level is set to 2.

This proper stock level changes as the operating time increases. For example, in the above example, when the A-type switches are sequentially replaced, if the operation time of some of the A-type switches exceeds a threshold value, the appropriate stock level is incremented by a predetermined value, for example, one. .
Thus, the appropriate stock level changes according to the operating hours of the component parts. In this example, only one threshold value is provided, but a plurality of threshold values can be provided.

The manufacturer ID is data for specifying the manufacturer of the component. Used to order components manually or automatically when the inventory of components is less than the proper inventory level. Manufacturer I
D is, for example, a mail address. When the stock number of the component is lower than the proper stock level, an order instruction is automatically issued to the mail address via the Internet. Therefore, there is no omission of order for component parts.

The maintenance criterion list 34-8 is used for calculating the remaining life and determining an appropriate stock level as shown in FIG. The maintenance criterion list 34-8 has fields of an operation upper limit and a threshold. The operation upper limit indicates the expected life of each component. The threshold value is used as a criterion as to whether or not to update the appropriate stock level, as described above.

The staff schedule, as shown in FIG. 9, indicates the work schedule of the serviceman. This makes it possible to determine the date and time when the serviceman's schedule is not full. Schedules that cannot be changed are indicated by solid lines, and schedules that can be changed are indicated by dotted lines. Therefore, even if the schedule is stuck, it is possible to determine whether or not the schedule can be postponed, so even when the schedule for maintenance and inspection is suddenly changed,
We can respond enough.

The maintenance inspection schedule table 34-12 has a format shown in FIG. 10, and shows a work schedule for each device. Also, the number of personnel required for maintenance and inspection is specified. In this example, it is set that two service personnel are required for maintenance and inspection of the device (1) and the device (2). Maintenance inspection schedule 34-12
Is created based on the overall operation data and the operation schedule table obtained from the monitoring device 10-1.

Next, the operation of the maintenance management system of the present invention will be described.

Next, a process when a failure occurs in the user A side 2-1 device will be described.

FIG. 11 shows the processing when a failure first occurs.
This will be described with reference to FIG.

First, when a failure occurs (step S
2), the cause of the failure is found and repair is performed. In step S4, it is determined whether or not parts need to be replaced for repairing the failure. If the parts do not need to be replaced, the repair is performed as it is (step S20). When it is determined that the parts need to be replaced, the technician on the side of the user A operates the input unit 18 to operate the parts inventory list 16-4.
Is displayed on the display unit 20. Thus, the user A technician can determine whether or not there is a replacement part at hand. If you have a replacement part, use it to repair the fault.

If the replacement parts inventory is displayed as 0 in the parts inventory list 16-4, the user A engineer operates the input unit 18 to request the center engineer to arrange replacement parts. This request is sent to the communication unit 16 via the control unit 12.
Is transmitted to the center device. When this request is received by the communication unit 32, the center engineer sends the request to the storage unit 34.
Of the entire parts inventory list 34-4 of the
To be displayed. In this way, it is determined whether or not the requested part is in stock at the center side (step S6).

When there is a maintenance part at the center, the part is delivered to the user A (step S22). When there is no maintenance part at the center side, it is checked whether or not a replacement part is stocked by another user (step S).
8). If the replacement part is not in stock at another customer, the part is manufactured and delivered to the user A (step 2).
4). If the replacement part is stocked at another customer, it is checked whether there is enough room for the part (step S1).
0). If there is no spare part in stock, parts are ordered and delivered to user A (step S24). If there is a margin in the parts inventory, it is determined whether there is a margin in the remaining life of the part (step S12). This takes into account the aging of components. If the remaining life of the part is sufficient, the part is transferred from another user to user A,
Repair is performed (step S26). If there is no remaining life of the part, the part is ordered and delivered to the user A and another user (step S14). Thus, the user-side technician can obtain the replacement part and perform the repair.

According to the present invention, even if the customer does not have all the maintenance parts in stock, it is sufficient if the customer has some maintenance parts in stock. The exchange of maintenance parts between the service station and other customers can reduce the number of stocked maintenance parts and reduce downtime of the crane. As a result, the running cost of the device can be reduced.

When the technician on the side of the user A performs repairs using the replacement parts on hand, the parts inventory list 16-4 is read out using the input unit 18 and displayed on the display unit 20. Reduce the number of parts in stock by the amount used. When a part is obtained from another user or from the center, the stock number of the corresponding part in the parts stock list 16-4 is increased by the obtained amount. In this way, the parts inventory status of the user A is always reflected in the parts inventory list 16-4. Parts inventory list 16-
It is desirable that, when 4 is updated, the parts inventory list 16-4 is automatically transmitted to the center device 4 simultaneously with the update.

As described above, when a part is obtained or when a part is used, the user A 2-1 determines the number of parts in stock used or obtained by the user A from the input unit 18. Is increased or decreased. As a result,
In the parts inventory list 16-4, the correct parts inventory numbers are always recorded in the parts inventory list 16-4.

In the center device 4, the control unit 30 transmits a component list transmission request via the input unit 36 from the communication unit 32 to the monitoring device 10-1. In the monitoring device 10-1,
In response to the component list transmission request received by the communication unit 14, the control unit 12 stores the component inventory list 1 from the storage unit 16.
6-4 is read out, and the center device 4
Send to In the center device 4, the control unit 30 receives the parts inventory list via the communication unit 32. Control unit 30
Is based on the parts inventory list, the entire parts inventory list 3
The value of the stock quantity field of 4-4 is updated.

In this example, the parts inventory list 16-4 of the monitoring device 10-1 is transmitted in response to a parts list transmission request from the center device 4. However, the control unit 12 of the monitoring device 10-1 transmits the parts inventory list 16-4.
Is updated, the list 16-4 may be automatically transmitted to the center device 4 without the request for transmitting the component list from the center device 4. Subsequent processing is the same as described above.

After the failure of the device (1) is repaired,
The worker of the user A controls the operation of the device (1) 6-1 using the monitoring device 10-1. At this time, the control unit 12
Is an instruction input by a worker via the input unit 18,
In addition, the status of each component of the device (1) 6-1 is monitored to detect the operation status. The operating state includes, for example, how many times the limit switch has been switched, the amount of current supplied to the motor, the temperature of the motor, the moving distance of the moving vehicle portion of the crane, and the like. The weight of the load being lifted by the crane is not directly measured,
It can be indirectly known from the amount of current supplied to the motor. Alternatively, the weight of the load may be supplied other than as the operation data. The detected operation status of each component is stored in the storage unit 16 as operation data 16-2.

The control unit 12 periodically operates the operation data 16-
2 is read from the storage unit 16 and transmitted to the center device 4 by the communication unit 14. For example, it is sent at a fixed time every day. However, it may be sent every hour, every half day, every week. However, if the transmission interval becomes longer,
The amount of data to be stored in the storage unit 16 increases. In the case of frequent transmission, the number of times of communication increases and the communication cost increases. Therefore, an optimal transmission interval is set for each device maintenance management system. Also, in the above example,
The operation data 16-2 is transmitted periodically by the control unit 12, but may be transmitted in response to an instruction from the center device 4. Alternatively, both may be used in combination.

The control unit 30 of the center device 4
2 receives the operation data 16-2. Control unit 30
Receives the operation data 16-2, reads out the entire operation data 34-2. The read whole operation data 34
Out of -2, the control unit 30 updates the integrated operation data based on the received operation data 16-2. For example, A
If the operation status of the type switch (1) is 500 times and the total operation data 34-2 is 8000 times as the integrated operation data, the integrated operation data of the A type switch (1) is 85
Updated to 00 times. Thus, the overall operation data 34-
2, the latest integrated operation status is stored for each user, device, and component.

Next, the control unit 30 sets the maintenance reference list 34
-8 is read out, and the updated accumulated operation data, the operation upper limit data of the maintenance reference list 34-8 and the threshold value are compared for each part. When the updated integrated operation data is equal to or larger than the operation upper limit data, it is necessary to immediately replace the component. However, such a situation does not occur in the maintenance management system of the present invention. When the updated integrated operation data is less than the operation upper limit data, the updated integrated operation data is compared with a threshold. If it is less than the threshold value, no operation is performed and the process ends. When the updated integrated operation data is equal to or larger than the threshold value, the control unit 30 reads the entire parts inventory list 34-4 and increments the appropriate inventory level by one. For example, if the accumulated operation data of the A-type switch (1) is 8500 and the threshold value is 8000, it is desirable that the A-type switch is replaced, and the appropriate stock level is 3 to 4.
Is incremented. Thereafter, the control unit 30 determines whether or not the stock quantity of the entire parts stock list 34-4 is equal to or more than the appropriate stock level. If the stock quantity of the whole parts stock list 34-4 is equal to or more than the appropriate stock level, the processing is ended.

When the user A is notified that the ship has entered, the technician of the user A instructs the input section 18 to create an operation schedule. In response to this instruction, the form of the operation schedule is read out and displayed on the display unit 20. The technician on the side of the user A inputs various data to the form of the operation schedule from the input unit 18. For example, the scheduled date and time of mooring, the scheduled date and time of departure, the amount of unloading containers, the amount of loading containers, and the like. When the input is completed, the operation schedule table 16-6 is stored in the storage unit 16. In this case, the operation schedule table 16-6 is
The information may be automatically transmitted to the center device 4 at the same time as the update, or may be read by the center device 4 later.

The operation schedule table 16-6 indicates that, for example, the equipment (1) 6-1 has entered the ship in April and early May, and is in the operation state. In addition, there are ships entering from late May to early June, and late June, and they are in operation. In addition, the equipment (2) in the same container yard of the same user A has entered the ship and is in operation from mid-April, from early May to mid-May, and all the way to June. . Thus, an operation schedule table is created as shown in FIGS.

In the center device 4, in response to the read instruction from the input unit 36, the control unit 30 controls the communication unit 32 to transmit the read instruction to the monitoring device 10-1. The control unit 12 of the monitoring device 10-1 transmits the operation schedule table 16
-6 is read out and transmitted to the center device 4. In the center device 4, the control unit 30 receives the operation schedule of the device (1) and stores it in the storage unit. Similarly, in response to the read instruction from the input unit 36, the control unit 30 controls the communication unit 32 to transmit the read instruction to the monitoring device 10-2. The control unit of the monitoring device 10-2 reads the operation schedule table and transmits the operation schedule table to the center device 4. In the center device 4, the control unit 30 receives the operation schedule of the device (2) and stores it in the storage unit.

When the operation schedule of the necessary equipment is received, the control unit creates the maintenance inspection schedule 34-12 as follows. It is not efficient to perform the maintenance and inspection of the device (1), return, and then return to the user A to perform the maintenance and inspection of the device (2). Unless the operation schedule cannot be adjusted by all means, it is more efficient to inspect the device (1) and the device (2) continuously. In addition, it is problematic to perform inspections after the maintenance inspection time has passed.

Accordingly, first, the value of the remaining life field of the overall operation data 34-2 is divided by the value of the average operation rate field, the one with the shortest remaining life is searched, and the first time schedule at which maintenance and inspection are to be performed is determined. decide. Next, an earlier time is determined by comparing the first scheduled time with the maintenance inspection time determined based on the previous maintenance inspection. Thus, the final time of the maintenance inspection is determined. Next, a time period during which the standby state of the device (1) and the device (2) continues during the maintenance and inspection period is searched.
As is clear from FIGS. 4 and 5, the device (1) has a standby time in mid-May, and the device (2) has a standby time in late May. Therefore, the control unit 30 selects the maintenance and inspection time of the device (1) in the middle of May, and selects the maintenance and inspection time of the device (2) in the middle of May. Thus, maintenance and inspection of the device (1) and the device (2) can be performed continuously. When determining the maintenance and inspection time, the control unit 30 writes the inspection time in the maintenance and inspection schedule 34-12, as shown in FIG. In this way, the schedule for the maintenance inspection can be automatically determined.

Next, the control unit 30 sets the personnel schedule 34-1.
Referring to 0, check the schedule of the serviceman. In this example, it is assumed that two service personnel are required for periodic inspection. At this time, it is assumed that the serviceman A has no schedule from the middle of May. In addition, serviceman B is scheduled for April and late May to June. However, the schedule from late May to early June is not fixed but can be changed. Serviceman C and Serviceman D
Has a schedule that cannot be changed. Control unit 30
First designates the serviceman A based on the maintenance / inspection time in the maintenance / inspection schedule table 34-12. After that, the next serviceman is searched for, but servicemen B to D are busy. Then, the control unit 30 changes the serviceman B to D
Specify a service person who can change the schedule up to. In this example, it is the serviceman B. In this way, the servicemen A and B who perform the maintenance and inspection are designated.

Next, the control unit 30 reads out the entire parts inventory list 34-4 and checks whether or not there is an inventory of parts necessary for maintenance and inspection. This is performed by comparing the value of the appropriate stock level field with the value of the stock quantity field. If the stock numbers of all the parts are sufficient, the process ends. When a part whose stock quantity is insufficient is found, it is displayed on the display unit 38. At this time, it is desirable that the record of the component whose stock quantity is insufficient is displayed in a color different from the other components.

The operator of the center apparatus 4 double-clicks the manufacturer ID field of a record having a different display color in the entire parts inventory list 34-4. Control unit 3
0 recognizes this double click as an ordering instruction, and sends an order form for the number of parts equal to the difference between the value of the appropriate stock level field and the value of the stock quantity field to the company A which is the manufacturer of the part by e-mail. I do. In this e-mail, a date that is a predetermined number of days before the start time of the maintenance and inspection indicated in the maintenance and inspection schedule table 34-12 is set as the delivery date. In this way, the maintenance and inspection are performed in a state where all necessary parts are provided, so that the maintenance and inspection can be performed smoothly.

In the above description, the schedule for maintenance and inspection is determined, and the shortage of parts is determined. At this time, the parts have been ordered after the operator has confirmed the shortage. However, when the schedule for maintenance and inspection is determined, if parts are insufficient, an order may be automatically placed using the manufacturer ID. In this way, parts can be prepared without errors.

It will be apparent that the ordering of the parts may be performed not only when the maintenance and inspection is determined but also when the operation data is received.

[0064]

As described above, according to the present invention, the maintenance and inspection schedule can be determined from the operation status of the equipment and the operation schedule of the equipment. Therefore, the maintenance inspection schedule can be quickly determined without inconveniencing the user of the device.

Further, when the maintenance inspection schedule is determined, it is possible to determine the replenishment of the maintenance parts which will be required in the maintenance inspection, so that the maintenance inspection can be executed smoothly. At this time, necessary maintenance parts are automatically ordered, so that delays in maintenance and inspection due to omission of order can be prevented.

Further, when the maintenance and inspection schedule is determined, a service person who performs the maintenance and inspection can be determined and the work plan can be determined, so that the staffing of the service personnel can be optimized.

Further, even if it is not the time for maintenance and inspection, the necessity of replenishment of maintenance parts can be determined from the operation status of the equipment and the stock quantity of each part of the equipment. At this time, an appropriate inventory amount is obtained from the operation status of each component of the device. This proper stock amount is updated according to the operation status of the device. Therefore, it is possible to prevent a failure recovery from being delayed due to a shortage of components.
Also, at this time, since necessary maintenance parts are automatically ordered, delay of failure recovery due to omission of order can be reliably prevented.
