Description
Technical Field
The invention relates to an automatic maintenance person allocation system and an automatic maintenance person allocation method.
Background
Elevators such as elevators and escalators require maintenance checks to be performed periodically by maintenance personnel. In addition, maintenance work may be performed at any time according to the state of the elevator. When an abnormality notification device provided in an elevator such as an elevator detects that some trouble has occurred in the elevator, the abnormality notification device requests a monitoring center of a company that performs maintenance management on the elevator to dispatch a maintenance worker.
In addition, a manager of a building in which the elevator is installed may request the monitoring center to dispatch a maintenance worker by a telephone or the like. For example, in the case of an elevator, when a failure of a lighting fixture installed in a car, a failure of a destination floor registration button, a failure of a call button of a station, or the like occurs, a manager of a building in which the corresponding elevator is installed requests a monitoring center of the elevator to dispatch a maintenance person. In the following description, the dispatch request of these maintenance personnel is referred to as a standby (OnCall).
Generally, at a monitoring center receiving these calls, an operator investigates the day's work schedule of a plurality of maintenance persons disposed in a maintenance-responsible area of a building in which the corresponding elevator is disposed, and selects a maintenance person that can be dispatched. For example, a maintenance person who is likely to be near a building to be visited or a maintenance person who is not currently in operation is selected, and the operator inquires whether the selected maintenance person can travel to the corresponding building.
Here, if the inquired maintenance person has a response to be immediately reachable, the maintenance person is instructed to reach the building on standby. In addition, if the responses of all the maintenance workers to be inquired are responses that can be handled if the currently executed maintenance work is interrupted, the operator of the monitoring center selects the best maintenance worker in consideration of the work content of each maintenance worker on the day, the skills of the maintenance workers, and the like.
In this way, the operator checks the day schedule of work of the plurality of maintenance workers and inquires whether or not the job of the candidate can be selected by the driver is not a highly efficient maintenance worker selection job. That is, in the monitoring center, it is difficult to accurately determine which worker is to be interrupted when not only it is impossible to grasp whether or not the work of the maintenance worker is advanced according to the work schedule but also all the maintenance workers are performing the work.
Therefore, as a system for assisting the selection of a standby maintenance worker at the monitoring center, a system described in patent document 1 has been proposed.
In the System described in patent document 1, each maintenance person carries a communication device with a receiver of a GPS (global positioning System) for acquiring a current position, and the monitoring center displays the position of each maintenance person transmitted from the communication device on a map. Patent document 1 describes a technique in which a communication device carried by each maintenance person is connected to a small camera device called a wearable camera, an image captured by the camera is transmitted to a monitoring center, and an operator confirms the image received at the monitoring center.
In this way, the operator confirms the images transmitted from the communication devices carried by the respective maintenance personnel, and the operator at the monitoring center knows the state of whether the maintenance personnel is working inside the building or moving outside the building, and the operator is the target when selecting the maintenance personnel.
However, even if the technique described in patent document 1 is applied, it may be difficult to select an appropriate operator. For example, when there is no maintenance worker who moves near a building on standby and all workers are working in the building, the operator must determine which worker can interrupt the work based on the image in which the worker is working. However, when the maintenance work of the elevator is performed, the images in operation are all images of the maintenance work of the elevator, and therefore, any image is a similar image. Therefore, the operator needs to judge how far the job has proceeded from a plurality of similar images in the job, but such judgment is not easy.
Therefore, it cannot be said that only collecting images of a camera device connected to a communication device carried by an operator by a monitoring center always enables selection of an appropriate operator when standby is generated.

Detailed Description
An embodiment of the present invention (hereinafter referred to as "present example") will be described below with reference to the drawings.
[1, example of System Structure ]
Fig. 1 shows the overall system configuration of the present example.
This example is an example of an automatic worker assignment system for responding to standby of a maintenance worker who selects an elevator apparatus at the time of standby.
Fig. 1 shows an outline of the states of 4 maintenance workers 1A, 1B, 1C, and 1D managed by the standby worker automatic distribution system 4 of the present embodiment. The automatic worker assignment system 4 manages a plurality of maintenance workers on standby, but here, for the sake of a simple explanation, an example will be described in which 4 maintenance workers 1A, 1B, 1C, 1D are managed and workers are assigned on standby.
The maintenance worker 1A is performing maintenance work on the hoisting machine 2 of the elevator in the building in which the elevator to be maintained is installed, and is in a work execution state. The maintenance worker 1B is in the work completion state while completing the maintenance work of the hoist 2 in a building different from the maintenance worker 1A and generating the work completion report 3. The maintenance person 1C is in a moving state while walking, and the maintenance person 1D is in a moving state while using a vehicle.
The maintenance personnel 1A to 1D each carry a communication device 7, and the communication device 7 incorporates a GPS receiving unit 5 that receives signals from positioning satellites and locates the current position. As the communication device 7, for example, a smartphone or a tablet terminal is used.
The communication devices 7 carried by the maintenance personnel 1A to 1D are connected to the wearable camera 6. The wearable cameras 6 are attached to, for example, helmets worn by the maintenance personnel 1A to 1D during maintenance work, capture images of the images entering the field of vision of the maintenance personnel, and record the captured images. The wearable camera 6 is attached to the helmet, and various attachment methods such as putting the wearable camera 6 in a jacket pocket of the maintenance staff 1A to 1D, or attaching the wearable camera 6 to glasses may be employed.
The communication device 7 communicates with the monitoring center 8 of the elevator via a wireless telephone line or the like, and transmits information on the current position located by the GPS receiving unit 5, image information captured by the wearable camera 6, and the like to the monitoring center 8. The information may be transmitted from the communication device 7 to the monitoring center 8 constantly or intermittently at a fixed time interval. Alternatively, when standby correspondence is required on the monitoring center 8 side, information of the current position and information of the captured image may be transmitted to the monitoring center 8 by an instruction of the monitoring center 8.
Next, the structure of the monitoring center 8 will be described.
The monitoring center 8 shown in fig. 1 shows only a configuration required for the automatic distribution system 4 for the worker on standby.
The monitoring center 8 includes a serviceman position storage unit 9, a serviceman skill storage unit 10, a shape registration unit 11, an operating state determination unit 12, a standby serviceman selection unit 13, a standby reception unit 21, and a display unit 22 as a configuration required for the standby-compatible worker automatic distribution system 4.
The serviceman position storage unit 9 of the monitoring center 8 collects information on the current position located by the GPS receiving unit 5 transmitted from the communication devices 7 of the servicemen 1A to 1D, respectively, and performs serviceman position storage processing for storing the collected position information. The serviceman position storage unit 9 collects information on the current positions of the servicemen 1A to 1D, respectively, and thereby can list the servicemen in the maintenance area in charge of the building on standby at the monitoring center 8. For example, the position information stored in the serviceman position storage unit 9 is information linked to a map, and the positions of the servicemen 1A to 1D are displayed on the map displayed on the display unit 22 of the monitoring center 8, respectively.
The serviceman skill storage unit 10 stores therein skills indicating what trouble each serviceman managed by the automatic standby worker distribution system 4 of the present example can deal with. For example, the serviceman skill storage unit 10 stores a table in which information indicating the skill of each serviceman is combined with IDs identifying the communication devices 7 carried by all the servicemen.
The shape registration unit 11 stores in advance the shape information of a specific member to be handled by a maintenance worker during maintenance work of the elevator by the maintenance worker. At this time, the shape information of a part of the components stored in the shape registration unit 11 includes movement information indicating how the component moves during the maintenance work.
In addition to the shape information of the storage means, the shape registration unit 11 also stores shape information of the job completion report 3 and shape information of the object 18 (fig. 3) for determination during operation. Examples of the object 18 for determination during operation include a steering wheel of a vehicle (automobile), a guard rail on a road, a traffic signal on a road, and a traffic sign on a road.
The working state determination unit 12 performs the working state determination process for each of the maintenance workers 1A to 1D. That is, the working state determination unit 12 compares the image information sent thereto from the communication devices 7 of the maintenance workers 1A to 1D with the shape information stored in the shape registration unit 11, and determines whether the maintenance worker is in a working state or a moving state when the image information and the shape information match each other. The respective states of the maintenance workers 1A to 1D determined by the working state determination unit 12 are stored in the working state determination unit 12. An example of the determination of the state is specifically described later.
The maintenance worker selection unit 13 determines the position of each maintenance worker stored in the maintenance worker position storage unit 9, the skill of each maintenance worker stored in the maintenance worker skill storage unit 10, and the state of the maintenance worker determined by the work state determination unit 12 at the time of standby, and selects the maintenance worker corresponding to the standby. A specific example of the maintenance person selection process for selecting the maintenance person corresponding to the standing by the maintenance person selection part 13 will be described later.
The standby receiving unit 21 receives failure information transmitted from any one of the elevators being monitored by the monitoring center 8. The standby receiving unit 21 receives standby information when a manager or the like of a facility in which an elevator is installed requests a maintenance worker to be dispatched by telephone or the like. The process of receiving the standby information by the standby receiving unit 21 also includes information when the operator of the monitoring center 8 receives a request to dispatch a maintenance worker by telephone or the like. At this time, the operator of the monitoring center 8 inputs the standby information received by the telephone to the standby receiving unit 21.
The display unit 22 displays a list of results obtained by the standby-corresponding serviceman selection unit 13 selecting the serviceman, and the operator of the monitoring center 8 confirms the display contents of the display unit 22.
[2, example of hardware configuration of monitoring center ]
Fig. 2 shows an example of the hardware configuration of the monitoring center 8. The monitoring center 8 is constituted by a computer device C, for example.
The computer device C includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3, which are connected to a bus C4, respectively. The computer device C further includes a display unit C5, an operation unit C6, a nonvolatile memory C7, and an interface C8.
The CPU C1 reads out and executes software program codes for realizing the respective functions provided in the monitoring center 8 from the ROM C2. Variables, parameters, and the like generated during the arithmetic processing are temporarily written into the RAM C3. For example, the CPU C1 reads a program stored in the ROMC2, and executes the standby maintenance staff selection process in the standby maintenance staff selection unit 13.
Examples of the nonvolatile memory C7 include an HDD (Hard disk Drive), an SSD (solid state Drive), a flexible disk, an optical magnetic disk, a CD-ROM, a CD-R, a magnetic tape, and a nonvolatile memory. The nonvolatile memory C7 stores therein an OS (Operating System) and various parameters, and also stores therein a program for causing the computer device C to function as the monitoring center 8. Information stored in the monitoring center 8, such as position information of the maintenance worker, and shape information of skills, components, and the like, is also stored in the nonvolatile memory C7.
For example, an NIC (Network Interface Card) or the like can be used for the Interface C8, and various data can be transmitted and received via a LAN (Local Area Network) to which a terminal is connected, a dedicated line, or the like.
The operator of the monitoring center 8 uses the display section C5 or the operation section C6. For example, the operator specifies a specific maintenance worker as a maintenance worker corresponding to the standby state from the maintenance worker candidate list displayed on the display unit C5 by the operation of the operation unit C6.
[3 State of maintenance person and concrete example of whether or not to support waiting operation ]
Fig. 3 shows a specific example of processing for determining the states of the maintenance workers 1A to 1D and registering whether or not the maintenance workers can support the standby, based on the respective visual field images of the maintenance workers 1A to 1D obtained from the wearable camera 6, by the monitoring center 8 in the standby-support-worker automatic distribution system 4. When the state of the maintenance personnel 1A to 1D is determined from the visual field images of the maintenance personnel 1A to 1D, the monitoring center 8 compares the shape information of the elevator components and the like stored in the shape registration unit 11 in advance with the visual field images of the maintenance personnel 1A to 1D, and determines the state of the maintenance personnel.
As shown in fig. 3A, for example, the serviceman 1A is performing maintenance work of the elevator, removes the liner 14, which is one of the structural members of the hoist 2, holds it by hand, and performs inspection work of the hoist 2. At this point, the mount 14 is included in the image of the wearable camera that is transmitted to the monitoring center 8.
The working state determination unit 12 searches the lining board 14 from a database of shape information of the elevator member stored in the shape registration unit 11 in advance. When the retrieved liner 14 matches the liner 14 in the database of the shape information of the elevator component, the serviceman 1A automatically determines that the work of removing the liner 14, that is, the work related to the hoist 2 is being performed. In this way, the working state determination unit 12 determines that the state of the serviceman 1A is "working" 15, and stores "working" 15 as information on the serviceman 1A.
In this way, the work state determination unit 12 can determine whether or not the maintenance worker is performing the work of the elevator by comparing and determining whether or not the shape data of the component of the elevator apparatus is present in the image captured by the wearable camera 6 carried by the maintenance worker.
Further, the working condition determination unit 12 recognizes that the lining board 14 is moving, that is, that the lining board 14 is moved by the serviceman 1A, and thereby can further improve the accuracy of determining that the condition of the serviceman 1A is "working" 15. That is, the work state determination unit 12 detects a specific member of the lifter such as the lining 14, and when it is determined from the captured image that there is movement among the detected members, it may be determined that the member is "in work" 15. The information "in-working" when the movement is detected and the information "in-working" when the movement is not detected may be distinguished information. For example, the "in-process" may be set as "during execution of a job" when movement is detected, and the "in-process" may be set as "during preparation of a job" when movement is not detected. The determination of the movement may be made, for example, based on a case where the direction and size of each component extracted from the continuously acquired images change by a predetermined threshold value or more, a case where a predetermined component is recognized or not recognized by the continuous images, a case where the distance between the extracted component and another component changes by a predetermined value or more, or a combination of these cases.
In this way, the serviceman 1A can determine that the maintenance work of the hoist 2 is performed based on the detection of the lining 14, which is a structural member of the elevator. The shape registration unit 11 registers shape information of various components such as analysis and inspection at the time of maintenance work of the elevator, and thereby can accurately determine whether or not a maintenance worker is performing the work. In this case, the operation state determination unit 12 is provided in advance as a table in accordance with the degree of difficulty of the maintenance operation, the necessary operation time, and the degree of difficulty of the interruption of the operation for each device of the elevator, and thereby it is possible to perform the operation interruption possibility or the prioritization.
In the example of fig. 3A, since it takes time for the work to be performed when the "in-process" of the hoist 2 is detected by the detection of the lining 14, the work state determination unit 12 determines that it is difficult to support, and adds the information of "difficulty to support" to the information of the maintenance worker 1A.
In addition, as an example of determining that the standby response is easy, there is a case where the operation for replacing a fluorescent lamp in the car of the elevator is detected and the like, and the operation is completed in a short time.
Next, if the maintenance person 1B shown in fig. 3B is explained, the maintenance person 1B is in a state of completing the maintenance work of the hoist 2 and generating the work completion report 3.
The shape registration unit 11 stores the job completion report 3 as shape information in advance. The work state determination unit 12 searches the shape information registered in advance for the work completion report 3 stored in the shape registration unit 11, and when the results match, can determine that the maintenance worker 1B is currently generating a report in order to complete the predetermined work. At this time, the work state determination unit 12 determines that the state of the serviceman 1B is "work completed" 16, and stores the work completed "16 as information of the serviceman 1B.
In addition, when storing the information of "job completed" 16, the job state determination unit 12 adds information of "possible" to stand by.
Next, if the maintenance person 1C shown in fig. 3C is explained, the maintenance person 1C indicates a state in which the maintenance work and the report generation are completed and the maintenance person is moving. In this state, the maintenance person 1C cuts off the power supply to the wearable camera 6.
The working state determination unit 12 is in a state where an image captured by the wearable camera 6 worn by the maintenance person 1C is not obtained. At this time, the working state determination unit 12 determines that the state of the serviceman 1C is "moving" 17. In addition, when storing the information "moving" 17, the working state determination unit 12 adds information "can" correspond to standby. The "available" corresponding standby at this time is higher in priority than the "available" corresponding standby at the time of the maintenance worker 1B (the work completion report 3 is being generated).
Next, if the maintenance person 1D shown in fig. 3D is explained, the maintenance person 1D indicates a state in which the vehicle is running and moving. In this state, the wearable camera 6 photographs a steering wheel of an automobile, a guardrail on a road, a traffic signal on a road, a traffic sign on a road, and the like.
Here, the shape registration unit 11 stores shape information such as the steering wheel, the guard rail, the traffic signal, and the traffic sign as the object 18 for determination during operation, and the operation state determination unit 12 determines that the captured image matches the object 18 for determination during operation. Therefore, the working state determination unit 12 determines that the state of the serviceman 1D is "moving" 17. In addition, when storing the information "moving" 17, the working state determination unit 12 adds information "can" correspond to standby. The "available" corresponding standby at this time is set to the "available" corresponding standby having the higher priority, as in the case of the worker 1C.
In this way, the working state determination unit 12 can automatically determine the movement of the maintenance worker by comparing the image captured by the wearable camera 6 with the shape information stored in the shape registration unit 11.
[4, selected processing example of maintenance person on standby ]
Next, the process of selecting the maintenance worker on standby will be described based on the information on the state of determination of each maintenance worker.
Fig. 4 is a flowchart showing a process flow of selecting a maintenance worker during the standby. The standby-to-maintenance person selection unit 13 of the monitoring center 8 starts the maintenance person selection process by receiving the standby by the standby reception unit 21.
The maintenance person selection unit 13 for standby operation starts the maintenance person selection process, accesses the maintenance person position storage unit 9, and collects position information of all the maintenance persons in the maintenance area including the building on standby (step S1). In this way, the standby-corresponding serviceman selection unit 13 can specify the serviceman to be subjected to the standby in units of the maintenance area.
Next, the standby-corresponding maintainer selecting unit 13 accesses the maintainer skill storage unit 10, and further extracts a candidate maintainer having a skill that can be associated with the standby from the maintainers in the maintenance area extracted in step S1 in step S1 (step S2).
Further, the standby-corresponding serviceman selection unit 13 grasps the respective work statuses of the serviceman extracted in steps S1 and S2 (step S3). Here, the state a is acquired for each maintenance person: "in-process", state B: "job completion", state C: information of any job status of "moving".
Then, the standby serviceman selection unit 13 determines whether or not there is a state C: the "moving" maintenance person (step S4). Here, when the state C: when the maintenance person is "moving" (step S4, "on"), the corresponding maintenance person selection unit 13 is on standby to select the state C: the "moving" maintenance person (step S5). In addition, when there are multiple states C: when the maintenance person is "moving", the maintenance person selection unit 13 corresponding to the standby preferentially selects the maintenance person located closest to the building where the standby is generated.
In addition, in step S4, when state C: if there is no single "moving" serviceman (none at step S4), the standby serviceman selection unit 13 determines whether or not there is a state B: the maintenance person of "job completion" (step S6). Here, when the state B: when the maintenance worker is "job completed" (step S6, "present"), the serviceman selection unit 13 is on standby to select the state B: the maintenance person of "job completion" (step S7). In this case, similarly to step S5, when there are a plurality of maintenance workers in the same state (state B), the standby corresponding maintenance worker selecting unit 13 preferentially selects the maintenance worker located closest to the building where the standby is generated.
Further, in step S6, when state B: if no single serviceman exists for the "job completion" (step S6, "none"), the standby serviceman selection unit 13 determines that the status is "state a: whether or not there is a maintenance worker who is likely to interrupt the work among the maintenance workers who are "working" (step S8). Here, when in state a: if there is a serviceman who is likely to interrupt the operation (yes in step S8), the serviceman selection support unit 13 is on standby to select the corresponding serviceman (step S9). In this case, similarly to steps S5 and S7, when there are a plurality of maintenance workers in the same state (the state C is easily interrupted), the standby serviceman selection unit 13 preferentially selects the maintenance worker located closest to the building in which the standby is generated
Then, the standby-corresponding serviceman selector 13 gives a dispatch instruction to the building on standby to the serviceman selected in step S5, S7, or S9 (step S10). The dispatch instruction may be, for example, a communication device in which the corresponding serviceman selection unit 13 is placed on standby to automatically transmit information (e.g., mail) of the dispatch instruction to the corresponding serviceman, or the display unit 22 may display information of the serviceman selected by the corresponding serviceman selection unit 13 placed on standby and confirm that the operator who has displayed the information can contact the corresponding serviceman.
In step S8, the total membership is state a: when the operation is "in operation" and the operation is difficult to be suspended (none at step S8), the monitoring center 8 associates the waiting condition with the waiting time required by the manager of the building (step S11). The contact may be automatically made by the standby serviceman selection unit 13 or by an operator who confirms the result of selection by the standby serviceman selection unit 13 on the basis of the display unit 22.
After the process of step S11, a process of selecting a maintenance person is performed in another maintenance area close to the maintenance area where the corresponding building exists, by the process of step S1.
[5, display example of selected results ]
Fig. 5 shows an example of a display of the result selected by the standby serviceman selection unit 13. The result of the selection by the maintenance person is displayed on the display unit 22, for example.
As a selection result 100, a standby content 101, a maintenance staff candidate list 102, and a supplementary explanation 103 are displayed.
The contents 101 are displayed as specific contents such as "fluorescent lamp is broken" and the like, which requests the dispatch of maintenance personnel.
As the maintenance staff candidate list 102, for example, all the maintenance staff (or a predetermined number of maintenance staff whose priority is higher) in the maintenance area including the building on standby are displayed. In one column of the maintenance staff candidate list 102, names a to E of the respective maintenance staff (operators), information on the current position of the maintenance staff, the distance to the site where the standby was generated, the operation state, the maintenance staff skill levels (levels a to C), the availability/non-availability, and the priority order are displayed. The reason why the correspondence is "impossible" is displayed in the supplementary explanation 103. That is, the display is not applicable during the work, or is not applicable due to insufficient skills.
In the example of fig. 5, 5 maintenance workers a to E are shown, and a state is shown in which the maintenance worker B closest to the site where the standby is generated is selected as the first-in-priority order among 3 maintenance workers B, D, E whose dispatch for the standby is "possible" for each maintenance worker. The standby-corresponding serviceman selection section 13 dispatches the serviceman who instructed to be the first in the order of preference to the building to be referred to. Or the operator who confirms the display shown in fig. 5 contacts maintenance person B who is the first in the preferred sequence and dispatches to the building on standby. In this way, the maintenance person candidate list 102 displays information of maintenance persons that can respond to the dispatch request.
As described above, according to the standby-compliant operator automatic distribution system 4 of the present embodiment, the state of the maintenance worker (the working state, the moving state, and the like) can be accurately determined from the image captured by the wearable camera 6 connected to the communication device 7 carried by the maintenance worker. Therefore, the appropriate dispatched maintenance person on standby for the maintenance person of the elevator can be automatically selected according to the operation state of each maintenance person at this time. Further, when the operator of the monitoring center has a request for dispatching a maintenance worker, the operator does not need to select the job of the dispatched maintenance worker, and thus the burden on the operator can be reduced.
[6. modification ]
The present invention is not limited to the above-described embodiments, but includes various modifications.
For example, in the above embodiment, the wearable camera 6 is connected to the communication device 7 carried by the maintenance person, and the image captured by the wearable camera 6 is transmitted to the monitoring center 8. On the other hand, a device incorporating a camera unit such as a smartphone or a tablet terminal is used as the communication device 7, and an image captured by the camera unit incorporated in the communication device 7 is transmitted to the monitoring center 8.
Further, the state in which the maintenance worker is determined to be in operation can be compared with the shape information stored in the shape registration unit 11 to determine and register a more detailed operation state. For example, in the example shown in fig. 3A, as the serviceman 1A, information "liner board inspection work is being performed by the hoisting machine" may be registered, and the registered information may be displayed in the serviceman candidate list 102. Thus, the time until the completion of the work can be estimated, and when the maintenance worker is selected, the selection can be performed more reliably.
In the above embodiment, the GPS that is the system is applied to determine the position of the maintenance worker, but the position of the maintenance worker may be determined by a system other than the GPS. Alternatively, the acquisition process of the position information of the position of the maintenance person and the determination based on the distance of the position are omitted, and the maintenance person candidate is selected based on the state (work state or movement state) determined from the captured images of all the maintenance persons having the place where the dispatch request is made as the charge area.
In the above-described embodiment, the elevator is described as an example of the elevator, but the present invention is also applicable to a process of selecting a serviceman of another elevator such as an escalator. Alternatively, the present invention can be applied to selection processing by maintenance personnel of various devices and machines other than the elevator.
The above-described embodiments are examples explained in detail to facilitate understanding of the present invention, and are not limited to having all the configurations explained. Further, a part of the structure of a certain embodiment can be replaced with the structure of another embodiment or modification, and the structure of a certain embodiment can also be replaced with the structure of another embodiment or modification. Further, addition, deletion, and replacement of another configuration can be performed for a part of the configurations of the embodiment examples.
In addition, for example, a part or all of the above-described respective structures, functions, processing portions, processing units, and the like may be realized by hardware by integrated circuit design or the like. In addition, the respective structures, functions, and the like described above can be realized by software by interpreting and executing programs for realizing the respective functions by a processor. Information such as programs, tables, and files for realizing the respective functions can be placed on a recording device such as a memory, a hard disk, and an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, and a DVD.
The control lines and the information lines are lines considered necessary for the description, and the product is not necessarily limited to the control lines and the information lines. Virtually all structures can be considered interconnected.
