Description

[Technical Field]

[0001] The present invention relates to a restoration work support system and a restoration work support method for supporting restoration work. [Background technology]

[0002] Patent Document 1 discloses a knowledge system that automatically registers incident information, including failure information and recovery response details, as knowledge information when an incident is resolved, and makes it possible to easily and appropriately narrow down the knowledge information based on the contents of the incident when utilizing the knowledge information.

[0003] When a device is restored based on a notification of failure information from the device, the knowledge system registers first incident information, including the failure information and the response to the restoration, as knowledge information in the knowledge DB. Also, when a device is restored in response to a request from a device user, the knowledge system registers second incident information, including information about the failure that occurred in the device and the response to the restoration, obtained from the status management system using the device's identification information, as knowledge information in the knowledge DB.

[0004] Patent Document 2 discloses a work completion time prediction device for an automated warehouse that can improve the calculation accuracy of the predicted work completion time. In the work completion time prediction device, when a management controller outputs transport work instruction data, it extracts transport performance data from a transport performance database, including the same current position data, transport source data, and transport destination data as the transport work instruction data. The management controller then calculates an average work time by averaging the transport work time included in the extracted transport performance data. The management controller also reads increase / decrease parameters that match the transport situation when the transport work instruction data is executed, and calculates the predicted work completion time by correcting the average work time using the read increase / decrease parameters. Furthermore, if an abnormality is detected, the predicted work completion time is updated by adding the recovery time measured by a timer to the predicted work completion time.

DETAILED DESCRIPTION OF THE INVENTION

[0011] <Figure 1 Work planning support system configuration> 1 is an explanatory diagram showing an example of the system configuration of a work plan support system. The work plan support system 100 includes, for example, a collection device 101, a monitoring device 102, a management device 103, equipment 104, and a communication terminal 105. The collection device 101, the monitoring device 102, the management device 103, the equipment 104, and the communication terminal 105 are communicatively connected via a network 110 such as the Internet, a LAN (Local Area Network), or a WAN (Wide Area Network).

[0012] The collection device 101 is a computer that collects data. Specifically, for example, the collection device 101 receives sensor data 150 via the equipment 104 and the network 110.

[0013] The monitoring device 102 is a computer that monitors the state of the equipment 104, i.e., the sensor data 150, and supports recovery if an abnormality is detected. The monitoring device 102 has an equipment alert master 121 and a recovery master 122. The equipment alert master 121 is a table that defines alerts for the equipment 104. The recovery master 122 is a table that defines recovery work for the equipment 104.

[0014] The management device 103 is a computer that manages work plans. The work plan DB 130 is a database that stores work plans. A work plan is a plan that indicates the time-series process of work to be performed by the equipment 104, and is a plan to perform some kind of work (manufacturing work, transportation work, processing work, inspection work, etc.). In this embodiment, the work plan is updated whenever an incident occurs.

[0015] In FIG. 1, the collection device 101, the monitoring device 102, and the management device 103 are implemented as different computers, but at least two of the collection device 101, the monitoring device 102, and the management device 103 may be implemented as a single computer.

[0016] The equipment 104 is equipment (including the hardware configuration of a computer shown in FIG. 2, which will be described later) that manufactures or repairs products according to a work plan. The equipment 104 can be operated by a worker W. For example, the equipment 104 is responsible for the work of a certain process in a certain production line among a group of production lines. Therefore, the role and type of the equipment 104 differ depending on the production line to which it is assigned and the process it is responsible for.

[0017] Furthermore, the equipment 104 sets the reception date and time of the detection value 151 as the detection date and time 152. The equipment 104 sets a combination of the detection value 151, the detection date and time 152, the line code 153, and the equipment code 154 as sensor data 150 and transmits it to the collection device 101. The line code 153 is identification information that uniquely identifies the production line on which the equipment 104 that transmitted the sensor data 150 is located. The equipment code 154 is identification information that uniquely identifies the equipment 104 that transmitted the sensor data 150.

[0018] Furthermore, the equipment 104 determines whether or not an abnormality has occurred based on the detection value 151 from the sensor 140. If it is determined that an abnormality has occurred, the equipment 104 assigns an error code 155 indicating the type of abnormality to the detection value 151.

[0019] When an error code 155 is assigned, the equipment 104 transmits the detection value 151 from the sensor 140, the detection date and time 152, the line code 153, the equipment code 154, and the error code 155 to the collection device 101 as sensor data 150. The sensor data 150 assigned with the error code 155 is referred to as error sensor data 150.

[0020] The sensor 140 is connected to the equipment 104. The sensor 140 is a device that detects various behaviors of the equipment 104 and outputs the detected value 151 to the equipment 104. For example, the sensor 140 detects the temperature inside or around the equipment 104 as the detected value 151. For example, the sensor 140 detects the voltage inside the equipment 104 as the detected value 151. For example, the sensor 140 detects the weight of the workpiece transported to the equipment 104 as the detected value 151. The sensor 140 also detects the air pressure of the compressor inside the equipment 104 as the detected value 151.

[0021] The above-described detected value 151 is an example, and the type of detected value 151 varies depending on the equipment 104. The sensor 140 may output the detected value 151 and the detection date and time 152 to the equipment 104.

[0022] The communication terminal 105 is a computer that transmits data input by the worker W to the collection device 101, the monitoring device 102, the management device 103, and the equipment 104, and displays data received from the collection device 101, the monitoring device 102, the management device 103, and the equipment 104. The communication terminal 105 is, for example, a tablet, a smartphone, or a personal computer (whether desktop or laptop).

[0023] The management device 103 may accept data input through an operation by the worker W, or may display the data so that the worker W can visually recognize it, without transmitting or receiving data via the communication terminal 105.

[0024] <Figure 2 Example of computer hardware configuration> FIG. 2 is a block diagram showing an example of the hardware configuration of the computers (collection device 101, monitoring device 102, management device 103, equipment 104, and communication terminal 105) shown in FIG. 1. The computer 200 has a processor 201, a storage device 202, an input device 203, an output device 204, and a communication interface (communication IF) 205. The processor 201, the storage device 202, the input device 203, the output device 204, and the communication IF 205 are connected by a bus 206. The processor 201 controls the computer 200. The storage device 202 serves as a working area for the processor 201. The storage device 202 is a non-transitory or temporary recording medium that stores various programs and data. Examples of the storage device 202 include a read-only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), and a flash memory. The input device 203 inputs data. The input device 203 may be, for example, a keyboard, a mouse, a touch panel, a numeric keypad, a scanner, a microphone, or a sensor. The output device 204 outputs data. The output device 204 may be, for example, a display, a printer, or a speaker. The communication IF 205 connects to the network 110 and transmits and receives data.

[0025] <Figure 3 Equipment Alert Master 121> Fig. 3 is an explanatory diagram showing an example of the equipment alert master 121 shown in Fig. 1. The equipment alert master 121 is information that defines a fault, and has the following fields: line code 301, equipment code 302, error code 303, alert level 304, and alert name 305.

[0026] The line code 301 is identification information that uniquely identifies the manufacturing line on which the equipment 104 is located. The equipment code 302 is identification information that uniquely identifies the equipment 104. The error code 303 is identification information that uniquely identifies an error, i.e., a fault in the equipment 104. The line code 301, the equipment code 302, and the error code 303 are used to determine whether they match the line code 153, the equipment code 154, and the error code 155, respectively.

[0027] The alert level 304 indicates the level of warning according to the error code 303. In this example, the larger the value, the more severe the failure. Specifically, for example, when the alert level 304 is "1," that is, level 1, it indicates a minor alert that can be handled by a worker W at the manufacturing site. Specifically, for example, level 1 is a level for which a manual has been written to deal with the alert. When the alert level 304 is "2," that is, level 2, it indicates an alert that requires specialized knowledge and qualifications to recover. At level 2, the manual has been written to deal with the alert, but the assignment of an appropriate person is required. When the alert level 304 is "3," that is, level 3, it indicates an alert for which no method of dealing with the alert has been established. A message instructing an inquiry is added to the error sensor data 150 itself from the equipment 104.

[0028] The alert name 305 is a character string in natural language that indicates the fault in the equipment 104 corresponding to the error code 303. In Fig. 4, the alert level 304 has three levels, level 1 to level 3, but it may have two levels or four or more levels. The combination of the error code 303, alert level 304, and alert name 305 is referred to as fault definition information 300 that defines the fault.

[0029] <Figure 4 Recovery Master 122> Fig. 4 is an explanatory diagram showing an example of the recovery master 122 shown in Fig. 1. The recovery master 122 is information that defines recovery, and has the following fields: an error code 303, an alert level 304, an alert name 305, a recovery operation 401, an SOP (Standard Operating Procedures) 402, a recovery operation time 403, an operation qualification 404, and additional information 405.

[0030] The recovery operation 401 is a character string indicating the operation to recover from the failure identified by the error sensor data 150. The SOP 402 is a character string describing detailed instructions for the recovery operation 401. The column for SOP 402 is updatable. The recovery operation time 403 is the time required for the recovery operation 401. The column for recovery operation time 403 is updatable.

[0031] The work qualifications 404 are the qualifications of the worker W required for the recovery work 401. The additional information 405 is information that is added after the fact about the recovery work 401. By default, no data is stored in the additional information 405, but the columns of the additional information 405 can be updated.

[0032] <Figure 5 Alert identification sequence> FIG. 5 is an explanatory diagram illustrating an example of an alert identification sequence.

[0033] (Step S501) The equipment 104 transmits sensor data 150, which is a detection value 151 from the sensor 140, to which a detection date and time 152, a line code 153, and an equipment code 154 have been added, to the collection device 101. In step S501, the equipment 104 determines whether the detection value 151 from the sensor 140 is an abnormal value, and if it is not an abnormal value, transfers the sensor data 150 to the collection device 101.

[0034] If the detected value 151 is an abnormal value, the equipment 104 embeds an error code 155 corresponding to the sensor 140 in the sensor data 150 and transfers the sensor data 150 including the error code 155 to the collection device 101 .

[0035] (Step S502) The collection device 101 collects sensor data 150 transmitted from the equipment 104 .

[0036] (Step S503) The collecting device 101 transmits the collected sensor data group to the monitoring device 102. The collecting device 101 may transmit all of the transferred sensor data 150 to the monitoring device 102, or may transmit only the sensor data 150 with the error code 155 attached thereto to the monitoring device 102.

[0037] (Step S504) The monitoring device 102 receives the sensor data set.

[0038] (Step S505) The monitoring device 102 identifies the alert content from the error sensor data 150. Specifically, for example, the monitoring device 102 extracts the detection date and time 152, the line code 153, the equipment code 154, and the error code 155 from the error sensor data 150.

[0039] The monitoring device 102 also identifies an entry in the equipment alert master 121 with a line code 301, equipment code 302, and error code 303 that matches the extracted line code 153, equipment code 154, and error code 155, and identifies the alert level 304 and alert name 305 in the identified entry. In this way, the alert information 500 (detection date and time 152, error code 303, alert level 304, and alert name 305) is identified.

[0040] <Figure 6 Recovery work support sequence 1> Fig. 6 is a sequence diagram showing recovery work support sequence 1. Recovery work support sequence 1 in Fig. 6 is a recovery work support sequence when the alert level 304 of the alert information 500 identified in step S505 is "1". The management device 103 holds a work plan 601. The management device 103 manages work on the equipment 104 in accordance with the work plan 601.

[0041] (Step S601) The monitoring device 102 refers to the recovery master 122 to identify the recovery work 401 corresponding to the alert information 500 and the recovery work time 403 thereof.

[0042] (Step S602) The monitoring apparatus 102 transmits the identified recovery work 401 and recovery work time 403 , as well as the detection date and time 152 of the alert information 500 , to the management apparatus 103 as recovery work information 600 .

[0043] (Step S603) The management device 103 receives the recovery work information 600 .

[0044] (Step S604) The management device 103 modifies the work plan 601 using the detection date and time 152 and the recovery work time 403 of the recovery work information 600 received in step S603. Specifically, for example, the management device 103 identifies the start time and scheduled end time of the recovery work 401. The management device 103 provisionally sets the detection date and time 152 as the start time of the recovery work 401. Because the recovery work 401 actually starts after the detection date and time 152, the management device 103 may set the start time of the recovery work 401 to a date and time obtained by adding a predetermined time to the detection date and time 152.

[0045] The management device 103 sets the scheduled end time of the restoration work 401 by adding the restoration work time 403 to the start time of the restoration work 401 (detection date and time 152 ).

[0046] In the work plan 601, the management device 103 sets the period from the start time (detection date and time 152) of the recovery work 401 to the scheduled end time of the recovery work 401 as the scheduled recovery work period, and shifts the work after the start time (detection date and time 152) of the recovery work 401 by the recovery work time 403. If work occurs after the operation end time of the day, the management device 103 may modify the work plan 601 in accordance with a preset policy (not shown) so that the equipment 104 continues to operate after the operation end time, or may modify the work plan 601 so that the equipment 104 is not operated after the operation end time and is carried over to the next business day or later.

[0047] The work plan 601 corrected in step S604 is referred to as a work plan 602.

[0048] (Step S605) The monitoring device 102 transmits recovery support information 610 to the communication terminal 105. The recovery support information 610 includes at least the detection date and time 152 and the recovery work 401 out of the recovery work information 600, the SOP 402, and the work qualifications 404. The communication terminal 105 displays the recovery support information 610.

[0049] As a result, worker W visually checks the recovery support information 610 and inputs a command to start recovery work 401 into the communication terminal 105. Upon receiving the input to start recovery work 401, the communication terminal 105 starts counting the time required for recovery work 401. Then, worker W starts recovery work 401 for the equipment 104.

[0050] (Step S606) The communication terminal 105 waits for the alert level 304 to be changed from "1" to "3" by an input operation from the worker W (step S606: No). If the alert level 304 is changed from "1" to "3" (step S606: Yes), the sequence transitions to that of FIG. 9. If the alert level 304 is not changed from "1" to "3" (step S606: No) and the recovery work 401 is completed, the worker W inputs an end of the recovery work 401. When the communication terminal 105 receives the end input of the recovery work 401, the time when the end input is made is set as the recovery end time, the time required for the recovery work 401 is stopped, and the actual recovery work time is calculated.

[0051] (Step S607) The communication terminal 105 transmits the recovery work result 620 to the management device 103 .

[0052] [Figure 7 Recovery work results 620] 7 is an explanatory diagram showing an example of a recovery work result 620. The recovery work result 620 is generated by the communication terminal 105. The recovery work result 620 includes the detection date and time 152, a work start time 701, a work end time 702, an actual recovery work time 703, an error code 303, an alert name 305, an alert level 304, a recovery work 401, an SOP 402, and additional information 704.

[0053] Work start time 701 is the time when communication terminal 105 receives input for starting recovery work 401 through input operation from worker W. Work end time 702 is the time when communication terminal 105 receives input for ending recovery work 401 through input operation from worker W. Actual recovery work time 703 is the time required from work start time 701 to work end time 702.

[0054] The additional information 704 is a character string that is received by the communication terminal 105 through an input operation by the worker W. Specifically, for example, the worker W inputs information that he or she has noticed about the recovery work 401 into the communication terminal 105 as the additional information 704.

[0055] (Step S608) Returning to FIG. 6, if the management device 103 has not received the recovery work result 620 by the scheduled end time of the recovery work, it modifies the work plan 602. Specifically, for example, the management device 103 adds a predetermined time to the scheduled end time of the recovery work. The work plan 602 before the modification is referred to as work plan 602-1, and the work plan 602 after the modification is referred to as work plan 602-2. When there is no need to distinguish between the work plans 602-1 and 602-2, they are referred to as work plan 602.

[0056] (Step S609) The management device 103 receives the recovery work result 620 .

[0057] (Step S610) The management device 103 amends the work plan 602 to a work plan 603 based on the recovery work result 620. For example, if the recovery work is completed earlier than scheduled, the start time from the recovery in the work plan 602 is changed to a time obtained by adding a predetermined time (for example, 10 minutes) after the work completion time 702. Furthermore, the end time of the work plan 602 is shifted by the amount of the shift in the start time, and a work plan 603 is created with the start and end times of the work plan 602 changed.

[0058] (Step S611) The management device 103 transmits update information 630 to the monitoring device 102. The update information 630 is information for updating the recovery master 122, and includes, for example, the error code 303, the alert level 304, the alert name 305, the actual recovery work time 703, and the additional information 704 in the recovery work result 620.

[0059] (Step S612) The monitoring device 102 receives the update information 630 .

[0060] (Step S613) The monitoring device 102 updates the recovery master 122 based on the update information 630. Specifically, for example, the monitoring device 102 identifies the entry to be updated in the recovery master 122 using a combination of the error code 303, alert level 304, and alert name 305 included in the update information 630. The monitoring device 102 then updates the recovery operation time 403 in the entry to be updated to the actual recovery operation time 703. The monitoring device 102 also adds additional information 704 to the additional information 405 in the entry to be updated.

[0061] This completes the recovery work support sequence 1.

[0062] <Figure 8 Recovery work support sequence 2> Fig. 8 is a sequence diagram showing recovery work support sequence 2. Recovery work support sequence 2 in Fig. 8 is a recovery work support sequence when the alert level 304 of the alert information 500 identified in step S505 is "2", and unlike recovery work support sequence 1, worker W can check SOP 402. The same processes as in Fig. 6 are assigned the same step numbers and their explanations will be omitted.

[0063] (Step S801) The monitoring device 102 refers to the recovery master 122 to identify the recovery work 401 and SOP 402 corresponding to the alert information 500 and the recovery work time 403 thereof.

[0064] (Step S802) The monitoring device 102 transmits the identified recovery work 401 , SOP 402 , and recovery work time 403 , as well as the detection date and time 152 of the alert information 500 , as recovery work information 800 to the management device 103 .

[0065] (Step S803) The management device 103 receives the recovery work information 800 .

[0066] (Step S804) As in step S603, the management device 103 modifies the work plan 601 using the detection date and time 152 and the recovery work time 403 of the recovery work information 800 received in step S803.

[0067] (Step S805) The monitoring device 102 transmits recovery support information 810 to the communication terminal 105. The recovery support information 810 includes at least the detection date and time 152, the recovery work 401, and the SOP 402 out of the recovery work information 800, the SOP 402, and the work qualifications 404. The communication terminal 105 displays the recovery support information 810.

[0068] This allows worker W to visually check the recovery support information 810. Since the recovery support information 810 also includes the SOP 402, worker W can also visually check the SOP 402. Worker W inputs the start of recovery work 401 into the communication terminal 105. Upon receiving the input to start recovery work 401, the communication terminal 105 starts counting the time required for recovery work 401. Then, worker W starts recovery work 401 for the equipment 104.

[0069] If the recovery support information 810 includes the work qualification 404, the worker W will start the recovery work 401 if he / she has the work qualification 404, and if he / she does not have the work qualification 404, he / she will call another worker W who has the work qualification 404, and the other worker W will carry out the recovery work 401. It is also possible to instruct the recovery work 401 to a worker who has the work qualification 404 in the recovery support information 810.

[0070] When the process is executed up to step S613, the recovery work support sequence 2 ends.

[0071] <Figure 9 Recovery work support sequence 3> Fig. 9 is a sequence diagram showing recovery work support sequence 3. Recovery work support sequence 3 in Fig. 9 is a recovery work support sequence when the alert level 304 of the alert information 500 identified in step S505 is "3" or when the alert level 304 is changed to "3" in step S606 (step S606: Yes). The same processes as in Fig. 6 and Fig. 7 are assigned the same step numbers and their explanations will be omitted.

[0072] (Step S901) The management device 103 modifies the work plan 601 to a work plan 602 based on an input from a supervisor M. The supervisor M is a person who supervises a worker W.

[0073] (Step S902) As shown in steps S605 and S805, the monitoring device 102 transmits the recovery support information 610 and 810 to the communication terminal 105. The communication terminal 105 displays the recovery support information 610 and 810.

[0074] As a result, worker W visually checks the recovery support information 610, 810 and inputs the start of recovery work 401 into the communication terminal 105. Upon receiving the input to start recovery work 401, the communication terminal 105 starts counting the time required for recovery work 401. Then, worker W starts recovery work 401 for the equipment 104.

[0075] If the recovery support information 610, 810 includes the work qualification 404, the worker W will start the recovery work 401 if he / she has the work qualification 404, and if he / she does not have the work qualification 404, he / she will call another worker W who has the work qualification 404, and the other worker W will carry out the recovery work 401. It is also possible to instruct the recovery work 401 to a worker who has the work qualification 404 in the recovery support information 810.

[0076] (Step S903) When the recovery work 401 is completed, the communication terminal 105 creates the SOP 900 in response to an operation input by the worker W.

[0077] (Step S904) The communication terminal 105 transmits the restoration work result 620. The SOP 402 in the restoration work result 620 is the SOP 900 created in step S903.

[0078] When the process is executed up to step S613, the recovery operation support sequence 3 ends.

[0079] 6, 8, and 9, the monitoring device 102 updates the recovery operation time 403 in the entry to be updated to the actual recovery operation time 703. However, the monitoring device 102 may calculate a statistical value based on the actual recovery operation time 703 up to that point and the actual recovery operation time 703 received this time, and set the statistical value as the recovery operation time 403 in the entry to be updated. The statistical value may be an average value, a longest value, a shortest value, or a median value. The statistical value to be used is set in advance.

[0080] In this way, according to this embodiment, it is possible to determine an appropriate recovery operation depending on the abnormality.
