The robot control unit 25 included in the first control unit 21 executes the control program stored in the program storage unit 28 to perform processes such as control of the driving of the robot 1, various calculations, and various determinations. As an example, the robot arm 10 and the grip 17 are driven by controlling the driving of the driving unit, so that the object for producing the article is gripped, transported, assembled, inspected, and the like.

The actual performance information processing unit 26 processes the actual performance information of the robot 1. The actual performance information is information corresponding to the actual performance of the robot 1 operated under the control of the robot control unit 25. Specifically, the actual performance information processing unit 26 measures the operation time of the robot 1 and the cycle time representing one operation cycle based on the time counted by a timer, not shown. The actual result information processing unit 26 counts the number of products produced by the robot 1 and counts the number of acceptable products determined to be acceptable by inspection. The actual performance information processing unit 26 counts the number of errors occurring in the robot 1, and measures the time at which the error has occurred and stopped. The actual performance information processing unit 26 acquires the operation time, cycle time, production quantity, quality product quantity, error occurrence quantity, error stop time, and the like as actual performance information, and transmits the acquired actual performance information to the management device 3.

The backup processing unit 27 performs various processes related to the backup of the control program, the setting information, and the like stored in the program storage unit 28. Specifically, when a predetermined event occurs in which backup should be performed, the backup processing unit 27 generates backup data such as a control program and setting information, and transmits the generated backup data to the management device 3, and accumulates the backup data in the management device 3. When the backup data is transmitted from the management apparatus 3, the backup processing unit 27 restores the control program, the setting information, and the like based on the backup data. The backup data generated by the backup processing unit 27 includes basic information, operation log, and the like of the control device 2 in addition to the control program and the setting information.

Examples of the event to be backed up include an event that occurs periodically at predetermined time intervals, an event that occurs as the control program, setting information, or the like is updated, an event that occurs as the operation of the robot 1 is stopped or suspended, an event that occurs as an error or warning occurs in the robot 1 or the control device 2, an event that occurs when a variable value of the control program deviates from a normal value or the like and satisfies a predetermined condition, an event that occurs as a user interface such as an operation button or an operation panel connected to the control device 2 is operated, an event that occurs as an instruction to execute backup processing is output from the management device 3 or the terminal device 4, and the like.

The management device 3 is composed of, for example, a general-purpose computer, and includes a second control unit 31, a second storage unit 32, and a second interface unit 33. The second storage unit 32 and the second interface unit 33 are connected to the second control unit 31 via a bus or the like. The management device 3 manages the control device 2 and also functions as a server, and executes various operations in response to a request from the terminal device 4 or the like as a client. The management device 3 corresponds to a robot management device.

The second control unit 31 is configured to include a CPU, a RAM, a ROM, and other memories, and to control the operation of the management apparatus 3 by Operating in accordance with an OS (Operating System) and various application programs, not shown, stored in the second storage unit 32. The second control unit 31 includes an operation information generation unit 35 and a backup management unit 36 as functional units implemented by application programs. Details of these respective functional units will be described later.

The second storage unit 32 is configured by a storage device such as a hard disk drive or an SSD (Solid State Drive: solid state drive), and stores the OS and various application programs described above. The second storage unit 32 is provided with a backup storage unit 37 and a performance information storage unit 38. The backup data transmitted from the control device 2 is accumulated in the backup storage 37, and the actual performance information transmitted from the control device 2 is accumulated in the actual performance information storage 38.

The second interface unit 33 includes various interface circuits for communicating with an external device. The second interface unit 33 of the present embodiment includes an interface circuit for performing communication via the network NW.

The operation information generation unit 35 included in the second control unit 31 receives the actual performance information transmitted from the control device 2, stores the actual performance information in the actual performance information storage unit 38, and generates a plurality of types of operation information based on the actual performance information stored in the actual performance information storage unit 38 and various types of information input by the user. The operation information is information indicating the operation state of the robot 1, and for example, an operation rate, a cycle time, a qualified rate, the number of error occurrences, and an error stop time are generated as the operation information. The operation rate is a ratio of the actual operation time to the operation scheduled time, and the operation information generation unit 35 calculates the operation rate based on the operation time acquired as the actual performance information from the control device 2 and the operation scheduled time input by the user. The operation scheduled time is input to the terminal device 4 by a user, for example, and transmitted to the management device 3 via the network NW. The operation information generating unit 35 calculates a qualified product rate, which is a ratio of the number of qualified products to the number of produced products, based on the number of produced products and the number of qualified products acquired as actual result information from the control device 2. The values obtained as actual result information are directly used for the cycle time, the number of error occurrences, and the error stop time. The operation information generation unit 35 is equivalent to an operation information acquisition unit because it generates operation information itself or receives operation information from the control device 2.

The backup management unit 36 acquires and manages backup data transmitted from the control device 2. The backup management unit 36 in acquiring backup data corresponds to a backup acquisition unit. Specifically, the backup management unit 36 stores the backup data acquired from the control device 2 as a file in the backup storage unit 37 of the second storage unit 32. Since a plurality of backup data are accumulated in the backup storage unit 37, the backup management unit 36 stores the backup data in association with identification information for identifying each backup data. As the identification information, for example, a file name of the backup data and a backup date and time indicating a date and time when the backup data was generated are used. The backup management unit 36 performs processing for associating the operation information generated by the operation information generation unit 35 with the stored backup data. The correspondence of establishment of the operation information is described later.

The backup management unit 36 also functions as a WEB server, and causes the display device 45 of the terminal device 4 to display a WEB page 50 (see fig. 3) including a list of managed backup data in response to a request from the terminal device 4. When the control program and the setting information are restored, the user can access the WEB page 50 and select one backup data to be restored from the list of backup data. Therefore, hereinafter, the WEB page 50 is also referred to as a selection screen 50.

Fig. 3 is a diagram showing a selection screen 50 displayed on the display device 45.

As shown in fig. 3, the selection screen 50 includes an operation information specification section 51, a backup list 52, and a resume execution button 53. The operation information specification unit 51 displays the "operation rate", "cycle time", "qualified rate", "number of errors occurring", and "error stop time", which are the operation information generated by the operation information generation unit 35, and check boxes are provided for each operation information. The user can designate the operation information displayed in the backup list 52 from among a variety of operation information by checking one or more check boxes using the input device 44.

In the backup list 52, various information about the backup data stored in the backup storage 37 is displayed in a list form. The displayed information includes the name and form of the robot controller as the control device 2 that performs the backup, and also includes the file name and the backup date and time as the identification information of the backup data. In addition, operation information for a period in which the robot 1 is operated by the control program and the setting information included in each piece of backup data is displayed in the backup list 52. Specifically, of the operation information generated by the operation information generation unit 35, the operation information designated by the operation information designation unit 51 is displayed together with the operation period. The user can select one backup data to be restored from among the plurality of backup data stored in the backup storage unit 37 by referring to the displayed operation information by using the input device 44.

The restore execution button 53 is a button-like image that can be operated by a user, and the user can instruct to execute the process of restoring the backup data by operating the restore execution button 53 by using the input device 44.

Referring back to fig. 2, the terminal device 4 is constituted by, for example, a personal computer, a tablet-type portable terminal, or the like. The terminal device 4 includes a third control section 41, a third storage section 42, a third interface section 43, an input device 44, and a display device 45.

The third control unit 41 is configured to include a CPU, a memory such as a RAM and a ROM, and operates in accordance with an OS, not shown, and various application programs stored in the third storage unit 42, thereby controlling the operation of the terminal device 4. The third storage unit 42 is configured by a storage device such as a hard disk drive, an SSD, or a memory, and stores various data in addition to the OS and various application programs described above. The third interface unit 43 includes various interface circuits for communicating with an external device. The third interface unit 43 of the present embodiment includes an interface circuit for performing communication via the network NW.

The input device 44 is constituted by a keyboard, a pointing device, and the like, receives an input operation by a user, and transmits the input operation to the third control unit 41. The display device 45 is configured by a liquid crystal display, an organic EL (Electro Luminescence: electroluminescence) display, or the like, and displays an image under the control of the third control unit 41. The input device 44 may be configured integrally with the display device 45, such as a touch panel. The input device 44 and the display device 45 may be separate from the main body of the terminal device 4, as in a desktop computer.

In the third storage unit 42 of the present embodiment, at least a WEB browser is installed as an application program, and the selection screen 50 is displayed on the display device 45 through the WEB browser.

Next, a robot management method of the robot management system 100 will be described.

Fig. 4 is a flowchart showing the operation of the robot management system 100 when backup is performed, and includes steps S101 to S104 showing the operation of the control device 2 and steps S201 to S209 showing the operation of the management device 3.

As shown in fig. 4, in the control device 2, while the robot 1 is operating under the control of the robot control unit 25, the actual performance information processing unit 26 updates the actual performance information each time based on the operation performance of the robot 1, and in step S101, transmits the updated actual performance information to the management device 3.

In step S102, the backup processing unit 27 determines whether or not an event that should be backed up has occurred. Then, when an event has occurred (yes in step S102), the process proceeds to step S103, and when no event has occurred (no in step S102), the process returns to step S101, and update and transmission of actual performance information are repeated.

When an event that should be backed up has occurred and the process proceeds to step S103, the backup processing unit 27 acquires the control program, the setting information, the basic information of the control device 2, the operation log, and the like, which are the backup targets, from the first storage unit 22, and generates one piece of backup data in which these pieces of backup data are stored. Then, in step S104, the backup processing unit 27 transmits the generated backup data to the management apparatus 3, and ends the processing.

On the other hand, in step S201, the operation information generation unit 35 of the management device 3 determines whether or not the actual performance information is transmitted from the control device 2. Then, when the actual performance information is transmitted (yes in step S201), the process proceeds to step S202, and when the actual performance information is not transmitted (no in step S201), the process proceeds to step S204.

When the actual performance information is transmitted and the process shifts to step S202, the operation information generating unit 35 receives the transmitted actual performance information, and in the next step S203, the received actual performance information is stored in the actual performance information storing unit 38, and the process shifts to step S204.

In step S204, the backup management unit 36 determines whether or not backup data is transmitted from the control device 2. Then, when the backup data is transmitted (yes in step S204), the process proceeds to step S205, and when the backup data is not transmitted (no in step S204), the process returns to step S201.

When the process goes to step S205, the backup management unit 36 receives the transmitted backup data.

In step S206, the backup management unit 36 determines whether or not the control program and the setting information included in the received backup data are the same as those of the backup data stored in the backup storage unit 37 at the time of the last backup. Then, when the control program and the setting information are different from those of the previous time (no in step S206), that is, when the contents of the control program and the setting information have been changed from those of the previous time when the backup data was stored, the process proceeds to step S207. On the other hand, when the control program and the setting information are the same as those of the previous time (yes in step S206), the backup management section 36 ends the processing without saving the received backup data in the backup saving section 37. Although not shown, in this case, the backup management unit 36 extracts an operation log from the received backup data and adds the operation log to the backup data stored last time.

When the control program and the setting information of the received backup data are different from those of the previous one and the processing is shifted to step S207, the operation information generating unit 35 generates the operation information based on the actual performance information accumulated in the actual performance information storing unit 38 and various information input by the user. The operation information generated here indicates the operation status from the time when the last backup data was stored in the backup storage 37 until the current backup data was stored in the backup storage 37. That is, the operation state during which the robot 1 is operated with the control program and the setting information before the current change is performed, that is, the control program and the setting information included in the previous backup data is shown. Accordingly, in the next step S208, the backup management unit 36 performs a process of associating the operation information generated by the operation information generation unit 35 with the backup data stored in the backup storage unit 37 last time. The backup management unit 36 clears all of the actual performance information accumulated in the actual performance information storage unit 38. When the last backup data is the first backup data, the current backup data stored next corresponds to the second backup data.

In step S209, the backup management unit 36 stores the backup data received this time in the backup storage unit 37 of the second storage unit 32, and ends the processing. The control program and the setting information included in the backup data stored this time are changed, and actual performance information when the robot 1 is operated with the control program and the setting information is acquired in a period after that. Then, when the control program and the setting information are changed next time and the backup data is stored, the operation information is generated based on the actual performance information acquired so far, and is associated with the current backup data.

Next, a description will be given of a control program and setting information recovered from the backup data.

Fig. 5 is a flowchart showing the operation of the robot management system 100 when the control program and the setting information are restored, and includes steps S321 to S324 showing the operation of the terminal device 4, steps S221 to S224 showing the operation of the management device 3, and steps S121 and S122 showing the operation of the control device 2.

In step S321, the third control unit 41 of the terminal apparatus 4 requests the backup management unit 36 of the management apparatus 3 to display the selection screen 50 based on an input operation by the user on the WEB browser.

Upon receiving the request from the terminal device 4, the backup management unit 36 of the management device 3 generates page information indicating the selection screen 50 based on the backup data accumulated in the backup storage unit 37 and the operation information associated therewith in step S221. Then, in step S222, the backup management section 36 transmits the generated page information to the terminal apparatus 4.

In step S322, the third control unit 41 of the terminal device 4 receives the page information from the management device 3, and causes the display device 45 to display the selection screen 50 based on the page information via the WEB browser. When the selection screen 50 is displayed, the user can perform an operation of designating operation information to be displayed in the backup list 52 by the operation information designating unit 51 and an operation of selecting one backup data to be restored from among the backup data displayed in the backup list 52, using the input device 44.

In step S323, after any one of the backup data is selected, the third control unit 41 determines whether or not there is an operation performed on the resume execution button 53 by the input device 44, that is, an operation by the user instructing the resume. Then, when there is an operation of the resume execution button 53 (yes in step S323), the process proceeds to step S324, and when there is no operation of the resume execution button 53 (no in step S323), this step is repeated until the operation is performed.

When the restoration execution button 53 is operated to shift the process to step S324, the third control unit 41 requests the management device 3 to restore the control program and the setting information included in the selected backup data, and ends the process.

In step S223, the backup management unit 36 of the management apparatus 3 determines backup data to be restored based on a request from the terminal apparatus 4, and reads the backup data from the backup storage unit 37. Then, in step S224, the read backup data is transmitted to the corresponding control device 2, and the process ends.

The backup processing unit 27 of the control device 2 receives the transmitted backup data in step S121. Then, in step S122, the backup processing section 27 executes processing of restoring the control program and the setting information based on the received backup data. Specifically, the backup processing unit 27 stores the control program and the setting information included in the received backup data in the program storage unit 28, and ends a series of processes.

As described above, according to the present embodiment, the following effects can be obtained.

(1) According to the present embodiment, when selecting backup data to be restored, the user can easily select desired backup data by referring to the operation information because the operation information indicating the operation state of the robot 1 is displayed on the selection screen 50.

(2) According to the present embodiment, since the operation information displayed on the backup list 52 of the selection screen 50 can be designated by the operation information designating unit 51, the user can select and display the operation information to be referred to.

The above embodiments may be modified as follows.

In the above embodiment, the file name and the backup date and time are displayed in the backup list 52 of the selection screen 50 as the identification information of the backup data, but the identification information to be displayed is not limited to the above information. For example, the firmware version of the control device 2 may be acquired and displayed as identification information, or the condition for generating the backup data, that is, information indicating which event the backup data is generated from may be displayed as identification information. Thus, the identification information displayed in the backup list 52 preferably includes at least one of a file name, a backup date and time, a firmware version of the control device 2, and a generation condition of the backup data.

In the above embodiment, the operation information generating unit 35 generates the operation rate, the cycle time, the qualified rate, the number of error occurrences, and the error stop time as operation information that can be displayed on the backup list 52, but operation information other than the above may be generated, or none of the above may be generated. However, the operation information generated by the operation information generating unit 35 preferably includes at least one of an operation rate, a cycle time, a qualified rate, the number of error occurrences, and an error stop time.

In the above embodiment, the backup data generated by the backup processing unit 27 includes basic information and operation log of the control device 2 in addition to the control program and the setting information, but the configuration of the backup data is not limited to this. For example, information other than the above may be added, and the information other than the control program may not be included in the backup data. The configuration of the entire control program is not limited to each backup, and may be a configuration different from the previous one.

In the above embodiment, the configuration in which the management device 3 generates the operation information based on the actual performance information acquired from the control device 2 is shown, but the present application is not limited to this configuration. For example, the control device 2 may generate operation information, and the management device 3 may acquire the operation information. The management device 3 may be configured to acquire operation information input by the user using the terminal device 4 or the like.
