Description

Service providing device, service providing system, and computer-readable recording medium

The present invention relates to a service providing device, a service providing system, and a computer-readable recording medium.

The services (functions) realized by industrial machines and their control devices are wide-ranging. Generally, users purchase the services they need. The purchased service is set to take effect at or after the industrial machine is shipped. After that, it becomes possible to use the service permanently (for example, Patent Document 1).

Even for the same industrial machine, the required services can vary depending on the purpose of use and processing. Furthermore, at manufacturing sites over a certain scale, multiple industrial machines often operate simultaneously, and each machine may perform different processing tasks. The same service may not be needed at the same time.

The fees for processing-related services can be expensive. Therefore, if you pay a service provider a usage fee for all industrial machines that may use the same service to make it available, it will cause a big problem in terms of cost. In addition, unless each industrial machine is using the same service in parallel, only one industrial machine is using the service at the same time, so it is the user who pays the usage fee for the service for multiple machines. It feels expensive for some people. This poses an economic burden to users of industrial machinery and increases manufacturing costs, so in order to recover the cost, the cost must be passed on to the price of the processed product. Currently, there is no management or information provision means for shared use of these services.
Manufacturing sites require a mechanism that allows multiple industrial machines to share services.

The service providing device according to one aspect of the present disclosure allows the same service to be shared among multiple industrial machines exceeding the upper limit, within a range that does not exceed the upper limit for simultaneous use, of a service required by an individual industrial machine.

At least one industrial machine is managed, and the industrial machine outputs the request information to the service providing device, and based on the result of the judgment made by the judgment unit of the service providing device with respect to the request information, the industrial machine outputs the request information to the service providing device. It is a service provision system that allows shared use of services.

Another aspect of the present disclosure is a computer-readable record that records a program that causes a computer to operate as a service providing device that provides information for shared use of services that can be used by industrial machines among a plurality of industrial machines. a request reception unit that is a medium and receives a computer as request information including at least machine-specific information that uniquely identifies the industrial machine and requested service information that specifies a service for which the industrial machine wants to start or end shared use; The request information, the shareability information that associates the shareability of available services with the machine-specific information, the upper limit number of shares that can be shared regarding the available services, and the machine-specific information of the industrial machine currently being shared. information and shared management information including at least the current number of shares, a determining unit that determines whether or not to start or end shared use of the service specified in the request information; This is a computer-readable recording medium that records a program that operates as a shared service information providing unit provided to machines.

The interface 20 is an interface for connecting the CPU 11 of the service providing device 2 and the network 5. The network 5 may be a WAN (Wide Area Network) configured with a leased line or the like, or may be a wide area network such as the Internet. Connected to the network 5 are industrial machines 4 such as machine tools and robots installed in factories, fog computers (not shown), cloud servers, and the like. Each of these devices exchanges data with the service providing device 2 via the network 5.

FIG. 2 is a schematic block diagram showing the functions provided in the service providing device 2 according to the first embodiment of the present invention. Each function provided in the service providing device 2 according to the present embodiment is realized by the CPU 11 provided in the service providing device 2 shown in FIG. 1 executing a system program and controlling the operation of each part of the service providing device 2. .

The service providing device 2 of this embodiment includes a request receiving section 100, a determining section 110, a shared service information providing section 120, and a communication section 180. Further, the RAM 13 to the non-volatile memory 14 of the service providing device 2 have a shareability information storage area, which is an area for storing shareability information, which is information indicating whether or not a service that can be provided to each industrial machine 4 can be shared. 150, and a shared management information storage unit 160, which is an area for storing shared management information, which is information for managing services shared by the respective industrial machines 4.

For example, information for uniquely identifying the manufacturer of the industrial machine 4 (for example, Machine Tool Builder (MTB) number, etc.), information for uniquely identifying the user using the industrial machine 4 (for example, Machine Tool Builder (MTB) number, etc.) Tool User (MTU) number, etc.), information for uniquely identifying the industrial machine 4 owned by the user, and the like. The requested service information may have any structure as long as it can uniquely identify at least the service (function) of the industrial machine 4 managed by the service providing device 2. For example, it may be the name of the requested function or an appropriately assigned function number. Further, the requested service information may include the content of the request regarding the service (start of shared use, end of shared use, etc.). The request receiving unit 100 outputs the received request information to the determining unit 110.

[Amendment based on Rule 91 03.10.2022]
FIG. 3 is a diagram showing an example of request information. The first request information includes a request to start shared use of a service with a machine ID: 01-0002-03 as machine-specific information and a service number: J669 (NURBS interpolation) as requested service information. The second request information includes machine ID: 01-0002-03 as machine unique information, and information requesting the start of shared use of a service with service number J710 (involute interpolation) as requested service information. The third request information includes machine ID: 01-0002-03 as machine unique information, and information requesting the start of shared use of a service with service number J816 (cylindrical interpolation) as requested service information.

FIG. 4 is a diagram showing another example of request information. The first request information includes information indicating that the machine ID: 01-0002-03 is machine-specific information and the service number: J669 (NURBS interpolation) is requested to end shared use as requested service information. The second request information includes information indicating that the machine ID: 01-0002-03 is machine-specific information, and the service number: J710 (involute interpolation) is requested to end shared use as requested service information. The third request information includes information indicating that the machine ID: 01-0002-03 is machine-specific information, and the service number: J816 (cylindrical interpolation) is requested to end shared use as requested service information.

The determining unit 110 determines the request information received by the request receiving unit 100 from the industrial machine 4, the shared management information stored in the shared management information storage unit 160, and the sharing permission information stored in the sharing permission information storage unit 150. Based on this, the start and end of shared use of the service from the industrial machine 4 is determined. When the request information of the industrial machine 4 is input from the request receiving unit 100, the determining unit 110 uniquely identifies the industrial machine 4 from the machine-specific information of the request information. Next, the determining unit 110 refers to the shareability information storage unit 150 and searches for shareability information of various services related to the specified industrial machine 4.

FIG. 5 shows an example of shareability information stored in the shareability information storage unit 150. Sharing permission information is stored at least for each industrial machine 4 to be managed. Each shareability information is configured by linking at least information that can uniquely identify each service (service number, service name, etc.) and information related to whether the service can be shared with machine-specific information. In the example of FIG. 5, industrial machine 4 with machine ID: 01-0002-03 can share services with service numbers J669 (NURBS interpolation) and J816 (cylindrical interpolation). Furthermore, the service with service number J710 (involute interpolation) cannot be shared. The determining unit 110 refers to the sharing permission information related to the machine-specific information included in the request information, and specifies whether the requested service can be shared based on information that can uniquely identify the service. If shared use is not possible, it is determined that the requested service cannot be shared and the request is rejected.

If the requested service is available, the determining unit 110 further refers to the sharing management information to confirm the current number of shares for the service. FIG. 6 shows an example of shared management information stored in the shared management information storage unit 160. The shared management information is stored at least for each contracted machine user. Each shared management information is configured such that at least the maximum number of shares for each service, the current number of shares, and information unique to the machine being shared are associated with information that uniquely identifies the machine user (machine user number, etc.) be done. This upper limit number of shares may be set using the input device 71 of the service providing device 2 or the external device 72. Further, settings may be made via the network 5 from an external device such as a management terminal, fog computer, or host computer (not shown). In the example of FIG. 6, the machine user with the machine user number: 0002 has a service number J669 (NURBS interpolation) with a maximum number of shares of 4, a service number J710 (involute interpolation) with a maximum number of 5 shares, and a service number J816 (cylindrical interpolation) with a maximum number of shares. The number is 2 and the contract is signed. Furthermore, the services of J669 and J710 are not currently being used in common. Furthermore, the service of J816 is shared by two industrial machines 4 with machine IDs: 01-0002-05 and 01-0002-09. When the request is to start sharing a service, the determining unit 110 refers to the current number of shares of the service. If the current number of shares for the requested service is less than the registered upper limit number of shares, it is determined that shared use can begin. After that, the current number of shares of the service for which the start of shared use has been requested is added by the number of uses, and then the machine specific information of the industrial machine 4 to be shared is registered. On the other hand, if the current number of shares has reached the maximum number of shares, it is determined that shared use cannot be started. For example, when the shared management information is in the state illustrated in FIG. 6, assume that the first request information in FIG. 3 is received. In this case, since the current number of shared uses of the J669 service has not reached the maximum number of shares, the determining unit 110 determines that the J669 service can be shared. Then, as illustrated in FIG. 7, 1 is added to the current number of shares of J669 in the shared management information, and machine ID: 01-0002-03 is further registered in the shared machine specific information. On the other hand, assume that the third request information in FIG. 3 is received. In such a case, since the number of shared uses of the J816 service has now reached the upper limit number of shares, the determining unit 110 determines that the J816 service cannot be shared any more.

On the other hand, if the request is to end shared use of a service, the determination unit 110 refers to the machine-specific information that is currently using the service in shared use. If the machine-specific information of the industrial machine 4 requesting termination of shared use is registered as sharing the service, it is determined that shared use can be terminated. Thereafter, the current number of shares of the service for which termination of shared use has been requested is subtracted by the number of terminations, and then the machine specific information of the industrial machine 4 is deleted. On the other hand, if the machine unique information is not registered as sharing the service, the request to end the shared use is rejected. For example, when the shared management information is in the state illustrated in FIG. 7, assume that the first request information in FIG. 4 is received. In this case, since the service of J669 is currently being shared and used by machine ID: 01-0002-03, the determining unit 110 determines that the shared use of the service of J669 can be ended. Then, 1 is subtracted from the current number of shares of J669 in the shared management information, and the registration of machine ID: 01-0002-03 is also deleted. On the other hand, assume that the third request information shown in FIG. 4 is received. In such a case, since the service of J816 is not currently being shared by machine ID: 01-0002-03, the determining unit 110 rejects the request to end the shared use.

The shared service information providing unit 120 provides the industrial machine 4 with the determination result by the determining unit 110. The provided determination result is treated in the industrial machine 4 as information related to permission or refusal of starting/terminating shared use of a predetermined service. The determination result provided by the shared service information providing unit 120 includes at least information regarding whether or not the requested service can be shared, and information related to shared use (reasons for not being able to use the shared service, current number of shared uses of the requested service, etc.). , shared usage limit, etc.).

FIG. 8 shows an example of the determination result provided by the shared service information providing unit 120. In the example of FIG. 8, industrial machine 4 with machine ID: 01-0002-03 is permitted to start shared use of service J669 (NURBS interpolation). Furthermore, the J669 maximum number of shares and the current number of shared uses are also displayed.

FIG. 9 shows another example of the determination result provided by the shared service information providing unit 120. In the example of FIG. 9, industrial machine 4 with machine ID: 01-0002-03 is refused to start shared use of service J710 (involute interpolation). As a reason for this, it is also displayed that the service of J710 cannot be shared by industrial machine 4 with machine ID: 01-0002-03.

The communication unit 180 manages the exchange of information between the service providing device 2 and the industrial machine 4 via the network 5. Upon receiving the request information from the industrial machine 4, the communication unit 180 outputs the received request information to the request reception unit 100. Further, when the shared service information providing unit 120 outputs a determination result regarding the requested information, the output determination result is transmitted to the industrial machine 4. This information may be sent to the user of the industrial machine 4 or the manufacturer of the industrial machine 4 using other communication means such as e-mail.

The service providing device 2 according to the present embodiment having the above configuration provides service information that allows the same service to be shared and used among a plurality of industrial machines that exceed the upper limit number, within a range that does not exceed the upper limit number of shared uses. will be able to be provided. By creating an operational plan for industrial machinery that allocates service usage to each industrial machine within a range that does not exceed the upper limit of shared usage, it is also possible to develop efficient products with a small number of shared usage. Especially for users who have multiple machines that do not use the same service at the same time, it is possible to keep the service usage fee lower than if you purchase the service on a fixed machine. Each piece of information can also be set in consideration of the usage situation at the site. For example, regarding the shareability information, a service that is expected to have a low utilization rate in a predetermined industrial machine 4 may be set to be shareable, and then shared with other industrial machines 4. On the other hand, for services that are expected to have a very high usage rate in a given industrial machine 4, shared use is set to be disabled, and the service is purchased separately for exclusive use by the industrial machine 4. In addition, regarding the upper limit number of shares managed by shared management information, we have carefully examined the operation details of multiple industrial machines 4 that have been carried out at the site in the past, and set the value according to the number of simultaneous users of each service. All you have to do is sign a contract. By operating in this way, it is possible to achieve both efficient service usage and reduction of contract costs.

As a modified example of the service providing device 2 according to the present embodiment, the determination unit 110 determines, in response to request information for starting shared use of a service that comes after the current number of shares of the service reaches the upper limit number of shares, the request information. It may be configured such that it is not immediately determined that the request information cannot be shared, but is put on hold, and when the current number of shares becomes less than the upper limit number of shares, it is determined that the request information that was on hold can be shared. When configured in this way, for example, in response to request information that has been put on hold by the determining unit 110, the shared service information providing unit 120 responds to the fact that the request information has been put on hold. Then, we will notify you when it becomes available for shared use. It may be configured such that a plurality of pieces of request information can be put on hold. If multiple pieces of requested information are on hold and the current number of shares is less than the maximum number of shares, for example, the requested information may be made available for sharing on a first-come, first-served basis, or in a predetermined priority order. (For example, a priority order may be set in advance for each piece of machine-specific information) to enable shared use. With such a configuration, it is not necessary to send request information many times until shared use of a service is permitted, and it is possible to reduce the burden associated with shared use of a service.

Below, a service providing device 2 according to a second embodiment of the present invention will be described.
The service providing device 2 according to the present embodiment further includes additional conditions as request information in addition to machine-specific information and requested service information. The additional conditions include at least one of a shared usage upper limit time and a shared usage deadline. The shared use upper limit time is the upper limit time during which shared use can continue after the start of shared use. Further, the shared use period is the date and time when shared use can continue after starting. If the request information includes additional conditions, the determining unit 110 determines whether to end the shared use, taking into consideration the content of the additional information.

FIG. 10 shows an example of shared management information in the service providing device 2 according to this embodiment. As illustrated in FIG. 10, the shared management information according to the present embodiment includes information regarding the shared use upper limit time, the shared use time limit, and the current shared time. The shared use upper limit time and the shared use time limit are values set based on additional conditions in the request information. If these values are not set in the additional information, the corresponding values in the shared management information are not set (in the example of FIG. 10, the fact that no values are set is expressed as "-"). Furthermore, if a shared usage upper limit time is set, the current shared usage time, which is the time elapsed since shared usage started, is managed by shared management information. If a shared usage time is currently set, that value is updated by system software or the like as time passes.

The determination unit 110 according to the present embodiment checks for each registered machine-specific information whether either a shared usage upper limit time or a shared usage deadline is set for the shared service. Services for which no upper limit for shared use and no expiration date for shared use are set are treated as those that can be shared for an unlimited period of time. On the other hand, for services for which a shared use upper limit time is set, the shared use upper limit time set for the service is compared with the current shared use time at predetermined intervals. Then, when the current shared use time exceeds the shared use upper limit time, the determination unit 110 determines that the shared use of the service has ended. Furthermore, for a service for which a shared use time limit is set, the shared use time limit set for the service is compared with the current date and time at predetermined intervals. Then, when the current date and time becomes after the shared usage limit, the determining unit 110 determines that the shared usage of the service has ended. Other operations are similar to those of the service providing device 2 according to the first embodiment.

FIG. 11 shows an example of the determination result provided by the shared service information providing unit 120 according to this embodiment. In the example of FIG. 11, industrial machine 4 with machine ID: 01-0002-03 is permitted to start shared use of service J669 (NURBS interpolation). Additionally, the J669 shared use limit time is also displayed.

FIG. 12 shows another example of the determination result provided by the shared service information providing unit 120 according to this embodiment. In the example of FIG. 12, shared use of service J669 (NURBS interpolation) has ended in industrial machine 4 with machine ID: 01-0002-03. As the reason for termination, it is shown that the shared usage upper limit time has been reached, and the date and time when the shared usage started and the shared usage upper limit time set at that time are also displayed.

The service providing device 2 according to this embodiment having the above configuration is capable of managing the time for shared use of services. After starting shared use, you can automatically end shared use at a predetermined time without requesting to end shared use, which prevents you from forgetting to end shared use for services you no longer use. can do.

As a modification of the service providing device 2 according to the present embodiment, the shared use upper limit time and the shared use deadline may be configured to be set for each service instead of for each industrial machine 4. With this configuration, it is possible to perform flexible operations such as ending the shared use of a given service all at once at a given time (for example, a given manufacturing work unit time, the time when the day changes, etc.) becomes.

Below, a service providing device 2 according to a third embodiment of the present invention will be described.
The service providing device 2 according to this embodiment includes information related to the attributes of the industrial machine 4 as machine-specific information in the request information. Information related to the attributes of the industrial machine includes, for example, the type of the industrial machine (machining center, lathe, etc.), the performance of the industrial machine (number of control axes, number of systems, maximum spindle speed, etc.), equipment of the industrial machine (cutting fluid related information, etc.) This may include the presence or absence of a device, the presence or absence of a work supply device, the presence or absence of an automatic chip discharge device, etc. The request information includes attribute information of the industrial machine 4 at the time of requesting shared use of the service. If the machine-specific information in the request information includes information regarding the attributes of the industrial machine 4, the determining unit 110 considers the information regarding the attributes of the industrial machine 4 and determines whether shared use is possible.

FIG. 13 shows an example of sharing permission information in the service providing device 2 according to this embodiment. As illustrated in FIG. 13, the sharing permission information according to this embodiment includes information related to sharing usage conditions. The shared usage conditions are conditions for information related to the attributes of the industrial machine 4 that are required when using the service. Industrial machines 4 that do not meet this condition cannot share the service.

Similar to the service providing device 2 according to the first embodiment, the determining unit 110 according to the present embodiment refers to sharing permission information related to machine-specific information included in the request information, and makes a request based on information that can uniquely identify the service. Specify whether shared use of the service provided is possible. Also, at that time, it is determined whether the information related to the attributes of the industrial machine 4 included in the machine-specific information in the request information satisfies the shared usage conditions related to the requested service. If the information related to the attributes of the industrial machine 4 does not satisfy the shared usage conditions, the industrial machine 4 determines that the requested service cannot be shared and rejects the request. Other operations are similar to those of the service providing device 2 according to the first embodiment.

The service providing device 2 according to the present embodiment having the above configuration can eliminate requests for shared use from industrial machines 4 that cannot use the service, and can restrict unnecessary shared use. become.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented in various forms by making appropriate changes.
For example, the service providing system 1 in the embodiment described above has a configuration in which the sharing permission information storage section 150 and the sharing management information storage section 160 are built into the service providing device 2. However, as illustrated in FIG. 14, the shareability information storage unit 150 and the share management information storage unit 160 may be provided on a computer different from the service providing device 2.

Furthermore, the service providing system 1 in the above-described embodiment has a configuration in which the service providing device 2 and the industrial machine are connected via a network. However, the service providing device 2 may be configured on a control device that controls the industrial machine 4. With this configuration, when a service is used in the industrial machine 4, request information is output to a functional group corresponding to the service providing device 2 configured on the control device. Then, the determination result of the determination unit 110 is output as a response to the request information. By configuring the service providing device 2 on the control device, it is possible to utilize the functions of the present invention even in the industrial machine 4 that is disconnected from the network.
