The operation of the device control device 10 includes group update processing and device control processing. Group update processing is processing for updating a group corresponding to a moving object. Device control processing is processing for controlling a device based on a control policy.

As a premise of the group update process and the device control process, a plurality of groups are defined based on the position and set as the group information 31 . In Embodiment 1, a group is defined corresponding to each of a plurality of areas. A control policy is determined for each of the plurality of groups and set as policy information 32 .

A group update process according to the first embodiment will be described with reference to FIG.
Group update processing is performed when the position of the mobile unit is updated.

(Step S11: Position Acquisition Processing)
The position acquisition unit 21 acquires position information indicating the position of the mobile object.
In Embodiment 1, the position acquisition unit 21 acquires position information from the position information system 50 . The position information system 50 transmits the position information to the device control device 10 when the reader reads the information of the mobile object from the IC card assigned to the mobile object. Here, the position information is entry information indicating the entered area. The IC card contains the identification information of the moving body, and this identification information is also included in the position information and transmitted. Therefore, it is also possible to identify which moving object it is from the position information.

(Step S12: Group identification process)
Using the group information 31, the group identification unit 22 identifies a group corresponding to the position information acquired in step S11. In Embodiment 1, the group specifying unit 22 uses group information 31 to specify a group corresponding to an area corresponding to position information. The group identification unit 22 sets the identified group as a corresponding group corresponding to the moving object. The group specifying unit 22 updates the group corresponding to the moving object to the corresponding group specified in step S12.

Device control processing according to the first embodiment will be described with reference to FIG.
The device control process is executed when an operation instruction is given to the device. Devices are terminals, cameras, sensors, etc. registered in the system.

(Step S21: Policy reading process)
The policy verification unit 24 reads the control policy corresponding to the corresponding group for the moving object from the policy information 32 . The policy verification unit 24 reads the control policy corresponding to the latest corresponding group updated by the group update process.

(Step S22: Policy verification process)
The policy verification unit 24 determines whether or not the control policy read in step S21 is authorized to perform the operation instructed. Specifically, the policy verification unit 24 identifies a group corresponding to the position of the device to be operated. Then, the policy verification unit 24 determines whether or not the control policy has the authority to operate the device belonging to the specified group.
If the policy verification unit 24 has authority, the process proceeds to step S23. On the other hand, if the policy verification unit 24 does not have authority, the process proceeds to step S24.

(Step S23: First control execution process)
The control execution unit 25 notifies the device that it has the authority to perform the operation for which the operation instruction has been given. As a result, the control execution unit 25 causes the device to execute a process according to the operation for which the operation instruction is given.

(Step S24: second control execution process)
The control execution unit 25 notifies the moving body that it is not authorized to perform the operation for which the operation instruction has been given. At this time, the control execution unit 25 does not execute the process corresponding to the operation for which the operation instruction is given.

An example in which the equipment control device 10 is applied to a care facility will be described with reference to FIGS. 5 to 9. FIG.
As shown in FIG. 5, it is assumed here that the care facility has a first floor and a second floor, and a plurality of caregivers work there. In this example, the mobile is a human caregiver. A device operated by a caregiver who is a mobile body is a display terminal logged in by the caregiver. A specific example of the display terminal is a PC, a tablet terminal, or the like. PC is an abbreviation for Personal Computer.
Here, separate groups are defined for the first floor and the second floor. A caregiver on the 1st floor can view only the video of the camera installed on the 1st floor, and a caregiver on the 2nd floor can view only the video of the camera installed on the 2nd floor. . Camera A is installed on the first floor. Camera B and camera C are installed on the second floor. Therefore, the caregiver on the first floor can view only the video of camera A. A caregiver on the second floor can view only the images of camera B and camera C.
In order to enter the area on the first floor, it is necessary to hold the IC card over the reader X. In order to enter the area on the second floor, it is necessary to hold the IC card over the reader Y.

As shown in FIG. 6, in the group information 31, WorkerGroup1, which is a group corresponding to the area on the first floor, and WorkerGroup2, which is a group corresponding to the area on the second floor, are set. As shown in FIG. 7, in the policy information 32, operation authority is set for each area. For WorkerGroup1, a control policy is set that gives permission to view camera data on the first floor, and for WorkerGroup2, a control policy is set that gives permission to view camera data on the second floor.
Also, as shown in FIG. 8, the installation locations of the cameras A, B, and C are set. Cameras A, B, and C belong to groups corresponding to installation locations.

Assume that caregiver B moves from the first floor to the second floor. For example, caregiver B may be temporarily in charge of the second floor due to a shortage of caregivers in charge of the second floor. Then, the group update process shown in FIG. 3 is executed.
In step S11, when the caregiver B holds the IC card over the reader Y, entry information indicating that the caregiver B has entered the area on the second floor is transmitted as position information. The IC card contains the identification information of the caregiver B, and this identification information is also included in the location information and transmitted. Therefore, from the position information, it is possible to specify not only that the caregiver B has entered the area on the second floor, but also that the caregiver B has entered the area. The position acquisition unit 21 acquires the transmitted position information.
In step S12, the group identification unit 22 identifies WorkerGroup2 corresponding to the second floor as a corresponding group. Then, as shown in FIG. 9, the group specifying unit 22 updates the corresponding group of the caregiver B to WorkerGroup2.
Since Caregiver B moved from the 1st floor to the 2nd floor, he does not have viewing authority for the images of Camera A installed on the 1st floor, but has viewing authority for the images of Cameras B and C installed on the 2nd floor. become a state.

Assume that caregiver B has performed an operation to browse the video of camera C from the display terminal. Then, the device control processing shown in FIG. 4 is executed.
In step S21, the policy verification unit 24 reads out the control policy corresponding to WorkerGroup2, which is the corresponding group of caregiver B. FIG. In step S<b>22 , the policy verification unit 24 determines whether or not the user is authorized to perform an operation to browse the video of the camera C. At this time, the policy verification unit 24 identifies a group corresponding to the position where the camera C to be operated is installed. Then, the policy verification unit 24 determines whether or not the control policy has the authority to operate the device belonging to the specified group. As shown in FIG. 8, camera C is installed on the second floor. In other words, camera C belongs to the group on the second floor. In addition, as shown in FIG. 7, the control policy corresponding to WorkerGroup2 is given the right to view the camera data on the second floor. Therefore, the policy verification unit 24 determines that there is authority. Then, the policy verification unit 24 advances the process to step S23.
In step S<b>23 , the control execution unit 25 notifies the display terminal of the caregiver B that he/she is authorized to view the video of the camera C. FIG. Thereby, the control execution unit 25 controls the display terminal of the caregiver B to acquire and display the image of the camera C. FIG.

Here, it is assumed that the device operated by the caregiver who is a mobile body is a display terminal. However, the device operated by the mobile caregiver can also be considered as a camera. In this case, the control execution unit 25 causes the camera C to transmit the image to the caregiver B's display terminal in step S23.

An example in which the device control device 10 is applied to remote monitoring will be described with reference to FIGS. 10 to 12. FIG.
As shown in FIG. 10, it is assumed here that the building to be monitored has a first floor and a second floor, and a plurality of autonomous mobile robots are operating. In this example, the mobile object is an autonomous mobile robot. An autonomous mobile robot is equipped with a collection device that collects information. Here, the collection device is a device that uploads images captured by a camera to a server. The device operated by the autonomous mobile robot is a collecting device mounted on the autonomous mobile robot. Therefore, the position of the moving body and the position of the device to be operated are the same. The autonomous mobile robot gives an operation instruction to upload the video taken by the camera.
Here, separate groups are defined for the first floor and the second floor. It is assumed that the autonomous mobile robot on the first floor can shoot images and upload them to the server, and the autonomous mobile robot on the second floor cannot shoot images and upload them to the server. It is assumed that the autonomous mobile robot can receive instructions from the user regardless of whether it is on the first floor or the second floor.
In order to enter the area on the first floor, it is necessary to cause the reader X to read the IC card mounted on the autonomous mobile robot. In order to enter the area on the second floor, it is necessary to cause the reader Y to read the IC card mounted on the autonomous mobile robot.

As shown in FIG. 11, in the group information 31, normal, which is the group on the first floor, and secure, which is the group on the second floor, are set. As shown in FIG. 12, in the policy information 32, a control policy is set in which a video upload authority and an instruction reception authority are given to normal, and an instruction reception authority is given to secure. Only given control policies are set. The instructions are, for example, an instruction to make rounds, an instruction to transmit specified real-time data, and the like.

Assume that robot A, which is an autonomous mobile robot, moves from the first floor to the second floor. For example, it is conceivable that the robot moves to the second floor under the control of changing the area to be monitored at random. Then, the group update process shown in FIG. 3 is executed.
In step S11, when the IC card of robot A is read by reader Y, entry information indicating that robot A has entered the area on the second floor is transmitted as position information. The IC card contains the identification information of the robot A, and this identification information is also included in the position information and transmitted. Therefore, from the position information, it is possible to identify not only that the robot has entered the area on the second floor, but also that the robot A has entered the area. The position acquisition unit 21 acquires the transmitted position information.
In step S12, the group identification unit 22 identifies secure corresponding to the second floor as the corresponding group. Then, as shown in FIG. 13, the group specifying unit 22 updates the corresponding group of robot A to secure.

Assume that robot A performs an operation to upload a video. Then, the device control processing shown in FIG. 4 is executed.
In step S21, the policy verification unit 24 reads the control policy corresponding to the robot A corresponding group secure. In step S22, the policy verification unit 24 determines whether or not there is an authority to upload video. At this time, the policy verification unit 24 identifies the group corresponding to the position of the device that is the target of the upload operation. The device to be uploaded is the collection device mounted on the autonomous mobile robot, and the position of the device to be operated is the same as the position of the autonomous mobile robot. Therefore, the group corresponding to the position of the device to be operated is the second floor area (area corresponding to the secure group) specified in step S11. As shown in FIG. 12, the control policy corresponding to secure does not give the right to upload video. Therefore, the policy verification unit 24 determines that there is no authority. Then, the policy verification unit 24 advances the process to step S24.
In step S24, the control execution unit 25 notifies the robot A that it does not have the video upload authority. Then, robot A does not acquire and upload the video.

*** Effect of Embodiment 1 ***
As described above, the device control apparatus 10 according to Embodiment 1 identifies the corresponding group corresponding to the position of the moving body using the group information 31 in which a plurality of groups are determined based on the position. Then, the device control apparatus 10 according to Embodiment 1 controls the device operated by the moving object based on the control policy corresponding to the corresponding group among the control policies set for each group.
As a result, when the moving body moves, the device is controlled based on the control policy corresponding to the group corresponding to the moved position. Therefore, there is no need to change the setting of the control policy as the mobile body moves. Also, the control policy may be set for each group, and does not need to be set for each mobile unit. Also, when controlling a plurality of devices, the devices are managed in groups according to the setting positions of the devices, and the control policy is applied to the devices according to the groups. Therefore, it is not necessary to set a control policy for each device. Therefore, it is possible to appropriately restrict operations while reducing the time and effort required to set the control policy.

In nursing care facilities, the caregiver's assigned area may be suddenly changed due to sickness or the like of the caregiver. In this case, it is necessary to quickly change the data that can be viewed by the caregiver whose area of responsibility has changed. However, in some situations it may not be possible to immediately respond to changes in the data visible to system administrators.
Even in such a situation, the device control apparatus 10 according to Embodiment 1 changes the data that can be browsed by simply moving the caregiver. As a result, the area in charge of the caregiver can be changed without the trouble of the system administrator.

In remote monitoring, an autonomous mobile robot is used, and captured images may be uploaded to a server. However, there are cases where images should not be uploaded from the viewpoint of security or the like.
Even in such a situation, the device control apparatus 10 according to Embodiment 1 changes whether or not the image can be uploaded simply by moving the autonomous mobile robot. As a result, appropriate operation can be performed from the viewpoint of security and the like.

***Other Configurations***
<Modification 1>
The policy verification unit 24 may switch the control policy to be applied when information indicating an emergency or the like is transmitted from the mobile unit.
In the example of remote monitoring, assume that the autonomous mobile robot transmits information indicating an emergency or the like. In this case, even if uploading of images is normally prohibited, it may be possible to upload images to a server different from that of normal times. An unusual server is, for example, a server to which access control is stricter than that of an ordinary server.
This processing is implemented, for example, as follows. A group corresponding to an emergency is set in advance in the group information 31. - 特許庁Also, a control policy corresponding to the emergency group is set. Then, when the emergency information is acquired, the device control device 10 performs control based on the control policy corresponding to the emergency group.

Not limited to emergency situations, when other information is transmitted, the policy verification unit 24 may apply a control policy according to the transmitted information. If the moving object is a person, the other information may be information such as the physical condition of the person.

For example, position information indicating the position obtained by the equipment carried by the mobile object and the positioning device mounted on the equipment carried by the target object is periodically transmitted from the equipment. The position acquisition unit 21 acquires the position information of the moving object by reading the most recently acquired position information of the moving object.
The policy verification unit 24 reads from the policy information 32 a control policy corresponding to the site (group) to which the position of the mobile unit belongs.

The processing from step S42 to step S44 is the same as the processing from step S22 to step S24 in FIG.

An example in which the device control device 10 is applied to a construction site will be described with reference to FIGS. 21 to 23. FIG.
As shown in FIG. 21, it is assumed that a site supervisor is in charge of two sites, site X and site Y. Each site has a worker, but depending on the situation, the worker may also move to another site. Other sites may be sites other than sites X and Y.
Here, a group is defined for each site. The site foreman is controlled so that if he is at site X, he can send push notifications only to workers at site X, and if he is at site Y, he can send push notifications only to workers at site Y. be done.
A location sharing application program is installed in the site supervisor's mobile terminal and each worker's mobile terminal. A mobile terminal is a transmission device that performs push notifications. The position sharing application program periodically transmits the position (latitude, longitude) of the mobile terminal to the position information system 50 . Here, for each site, if the user is located within a certain range around the site, the user is assumed to be at the site. For example, using the maximum/minimum value of latitude and the maximum/minimum value of longitude for each site as site information, the position information system 50 uses the position transmitted from the mobile terminal of the site supervisor and the mobile terminal of each worker. Site supervisors and each worker are identified at which site.

As shown in FIG. 22, in the group information 31, XGroup, which is the group of the site X, and YGroup, which is the group of the site Y, are set. As shown in FIG. 23, in the policy information 32, control policies are set for the XGroup when the position indicated by the target information is the site X and for other cases. If the position indicated by the target information is the site X, a control policy is set that gives the push notification transmission authority. If the position indicated by the target information is other than the site X, a control policy is set in which the push notification transmission authority is not granted. Similarly, in the policy information 32, control policies are set for the YGroup when the position indicated by the target information is the site Y and for other cases. If the position indicated by the target information is the site Y, a control policy is set that gives the push notification transmission authority. If the position indicated by the target information is other than the site Y, a control policy is set in which the push notification transmission authority is not granted.

It is assumed that the site supervisor, worker A, and worker B are at site X, and worker C is at site Y. At this time, it is assumed that the on-site supervisor performs an operation to transmit a push notification from a portable terminal, which is a device. Then, the device control processing shown in FIG. 20 is executed.

In step S<b>41 , the position acquisition unit 21 acquires information from the position information system 50 as to which site the site foreman, who is a mobile body, is at. The location information system 50 acquires location information from the mobile terminal of the site supervisor and the mobile terminals of each worker. Based on this position information, the position acquisition unit 21 can identify which site (group) the site supervisor and each worker are at using site information. Then, the policy verification unit 24 reads the control policy corresponding to XGroup, which is a group corresponding to the site X where the site supervisor is present.
In step S42, the policy verification unit 24 acquires from the location information system 50 the information on which site the mobile terminal of each worker is located, and extracts the mobile terminal (equipment) assigned to the worker belonging to the XGroup. According to the control policy read out in step S41, devices assigned to workers belonging to XGroup have push notification operation authority. Therefore, the policy verification unit 24 advances the process to step S43. In step S43, the control execution unit 25 notifies the mobile terminal of the site supervisor that the site X has the push notification operation authority. Then, the control execution unit 25 transmits a push notification to workers A and B whose latest target information is site X, and does not transmit a push notification to worker C who is at site Y. FIG.

It is assumed that the site foreman operates the push notification from a position other than site X or site Y. FIG. In this case, the control policy corresponding to Zgroup is read in step S41. The control policy corresponding to Zgroup indicates that there is no push notification investigative authority. Therefore, in this case, the policy verification unit 24 advances the process to step S44. Then, the control execution unit 25 notifies the site supervisor's mobile terminal that he or she does not have the push notification authority.

Assume that worker A is moving from site X to site Y when the site supervisor issues a push notification at site X. In this case, the mobile terminal of worker A is not extracted as the mobile terminal assigned to the workers belonging to the XGroup in step S42. As a result, the control execution part 25 does not transmit the push notification to the worker A, and transmits the push notification only to the worker B in step S43.

Further, when the site supervisor moves from site X to site Y and performs a push notification operation, the policy verification unit 24 reads the control policy corresponding to group YGroup in step S41. In this case, the mobile terminal of worker C is extracted as the mobile terminal assigned to the workers belonging to YGroup in step S42. As a result, in step S43, the control execution unit 25 transmits the push notification to the worker C at the site Y, and does not transmit the push notification to the worker A and the worker B at the site X.
