Description

Technical Field

[0001] This invention relates to an access control device. Background Technology

[0002] Patent Document 1 discloses an access control device. When the access control device receives a request notification from a mobile body to pass through an access control device, it can make the access control device passable by opening the access control device.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-108219

[0004] However, in the access control device described in Patent Document 1, if a mobile body mistakenly sends a request to pass through an unrelated access device, the access control device opens that unrelated access device. Therefore, the security of access control is reduced. Summary of the Invention

[0005] This invention was made to solve the aforementioned problems. The object of this invention is to provide an access control device that improves security.

[0006] The access control device of the present invention comprises: a receiving unit that receives from a mobile body either a first request notification that the mobile body is passing through an access device or a report notification that the mobile body has completed passing through the access device, and first location information of the mobile body when the first request notification or the report notification was sent; and an authentication unit that, if it is determined from the first location information received by the receiving unit that the mobile body sent the first request notification or the report notification while located in a designated area, determines whether the mobile body has the authority to pass through the access device based on the first request notification received by the receiving unit, or determines whether the mobile body has completed passing through the access device based on the report notification received by the receiving unit; if it is determined from the first location information received by the receiving unit that the mobile body did not send the first request notification or the report notification while located in the designated area, it does not perform a determination of whether the mobile body has the authority based on the first request notification, or does not perform a determination of whether the mobile body has completed passing through based on the report notification, wherein the first request notification includes identification information of the access device.

[0007] Invention Effects

[0008] According to the present invention, when the access control device determines that a mobile body has the authority to pass or has completed the passage, it determines whether the mobile body has the right to pass or whether the mobile body has completed the passage when it determines that the mobile body is located in the designated area and sends the first request notification or report notification. Therefore, security can be improved. Attached Figure Description

Detailed Implementation

[0033] The embodiments for carrying out the invention will be described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals. Repeated descriptions of these parts are appropriately simplified or omitted.

[0034] Implementation Method 1

[0035] Figure 1 This is a top view of the management area of ​​the access management device in Implementation Method 1.

[0036] exist Figure 1 In the access control system shown, management zone 1 is located inside a building (not shown). Management zone 1 is divided into an internal zone 1a and an external zone 1b. Door 2 is provided as an entrance / exit device between internal zone 1a and external zone 1b. For example, access control device 3 is provided inside the building. Internal authentication zone 4a is provided around door 2 in internal zone 1a via access control device 3. External authentication zone 4b is provided around door 2 in external zone 1b via access control device 3.

[0037] Mobile body 5 is configured to move autonomously. Mobile body 5 is configured to communicate with access control device 3. Mobile body 5 is located inside the building. Figure 1 Multiple moving objects 5 are shown in the figure.

[0038] When mobile body 5 needs to enter internal area 1a from external area 1b, it moves towards the inside of external authentication area 4b. Upon completion of its movement towards external authentication area 4b, mobile body 5 generates a first request notification for passage through door 2, including the identification information of mobile body 5 and door 2. Mobile body 5 then sends information to access control device 3 that correlates the first request notification with its own position information at the time the first request notification was generated.

[0039] Upon receiving a first request notification, the access control device 3 determines, based on the first position information of the mobile body 5 corresponding to the first request notification, that the mobile body 5 sent the first request notification from the inside of the external authentication area 4b corresponding to the door 2. In this case, the access control device 3 determines whether the mobile body 5 has permission to pass through the door 2 as an authentication action for the first request notification. If the access control device 3 determines that the mobile body 5 has permission, it sends an open command to the door 2. Upon receiving the command, the door 2 opens.

[0040] Then, the mobile body 5 passes through door 2. After passing through door 2, the mobile body 5 generates a report notification in the internal authentication area 4a, which includes the identification information of the mobile body 5 and the identification information of door 2, indicating that passage through door 2 has been completed. The mobile body 5 sends information to the access control device 3 that corresponds the report notification with its own location information at the time the report notification was generated.

[0041] Upon receiving a report notification, the access control device 3 determines, based on the first position information of the mobile body 5 corresponding to the report notification, that the mobile body 5 sent the report notification from the inside of the internal authentication area 4a corresponding to the door 2. In this case, the access control device 3 determines whether the mobile body 5 has completed passage through the door 2 as an authentication action for the report notification. If the access control device 3 determines that the mobile body 5 has completed passage through the door 2, it sends a closing command to the door 2. Upon receiving the command, the door 2 closes.

[0042] When the mobile body 5 needs to exit from the internal zone 1a to the external zone 1b, the entry / exit management device 3 and the mobile body 5 perform the same actions as when the mobile body 5 needs to enter.

[0043] Next, use Figure 2 The entry and exit management device 3 will be explained.

[0044] Figure 2 This is a block diagram of the access management system using the access management device in Implementation Method 1.

[0045] like Figure 2 As shown, the access control device 3 has a storage unit 6, a receiving unit 7, and an authentication unit 8.

[0046] Storage unit 6 stores device information indicating the location of the device and the location of the area that exists in management zone 1.

[0047] The receiving unit 7 receives information from the mobile body 5.

[0048] When the receiving unit 7 receives the first request notification or report notification from the mobile body 5, the authentication unit 8 retrieves the device information corresponding to the door 2 from the storage unit 6 based on the identification information of the door 2 contained in the first request notification or report notification. The receiving unit 7 then determines, based on the first location information of the mobile body 5 corresponding to the first request notification or report notification and the device information, whether the first location of the mobile body 5 at the time the first request notification or report notification was sent was... Figure 2 The first position of the moving body 5, which is not shown in the diagram, is inside the internal authentication area 4a or the external authentication area 4b. If the authentication unit 8 determines that the first position of the moving body 5 when the first request notification or the report notification was sent is inside the internal authentication area 4a or the external authentication area 4b, the authentication unit 8 performs the authentication operation for the first request notification or the report notification.

[0049] Specifically, in the authentication process, the authentication unit 8 determines whether the mobile body 5 has permission to pass through door 2 based on the first request notification. If the authentication unit 8 determines that the mobile body 5 has permission to pass through door 2 based on the first request notification, it sends an open command to door 2. In the authentication process, the authentication unit 8 determines whether the mobile body 5 has completed passage through door 2 based on the report notification. Specifically, if the identification information of the mobile body 5 contained in the report notification matches the first request notification, the authentication unit 8 determines that the mobile body 5 has completed passage through door 2. If the authentication unit 8 determines that the mobile body 5 has completed passage through door 2 based on the report notification, it sends a close command to door 2.

[0050] According to Embodiment 1 described above, the access control device 3 includes a receiving unit 7 and an authentication unit 8. When the access control device 3 determines that a mobile body 5 has sent a first request notification or report notification while located within a designated authentication area, it determines whether the mobile body 5 has the authority to pass through the access control device, or whether the mobile body 5 has completed passing through the access control device. Therefore, security can be improved.

[0051] Furthermore, if the access control device 3 determines, based on the first request notification, that the mobile body 5 has permission to enter or exit the access device, it sends an instruction to open the access device. Therefore, the mobile body 5 is able to pass through the access device.

[0052] Furthermore, if the access control device 3 determines, based on a report notification, that the moving body 5 has completed passage through the access control device, it sends a closing command to that access control device. Therefore, passage through that access control device is prevented. As a result, security is improved.

[0053] Furthermore, when sending the first request notification, the mobile body 5 can also send entry / exit action information indicating either entry or exit to the access management device 3, corresponding to the first request notification. In this case, the access management device 3 can also determine whether the entry / exit action information matches the first location information. Specifically, if the access management device 3 receives entry / exit action information indicating entry and the mobile body 5's first location is the external authentication area 4b, it determines that the entry / exit action information matches the first location information. If the access management device 3 receives entry / exit action information indicating exit and the mobile body's first location is the internal authentication area 4a, it determines that the entry / exit action information matches the first location information. The access management device 3 can also perform the authentication action for the first request notification if it determines that the entry / exit action information matches the first location information. Therefore, the appropriateness of the first request notification can be determined more accurately. As a result, security is improved.

[0054] Alternatively, the access control device 3 can be installed in a different building than the building where the management zone 1 is located. In this case, the access control device 3 can also communicate between the door 2 and the moving body 5 via a communication line.

[0055] Alternatively, the storage unit 6 may not be located inside the access control device 3. For example, a storage device with the same function as the storage unit 6 may be installed in a different location from the access control device 3.

[0056] Alternatively, the entrance / exit device may not be door 2.

[0057] Figure 3 This is a top view of the management area of ​​the access management device in Implementation Method 1.

[0058] like Figure 3 As shown, security door 9 is installed as an entrance / exit device between internal zone 1a and external zone 1b. Security door 9 has multiple passages 10. In this case, it connects with... Figure 3 Similarly, the access control device 3 sends a command to the security door 9 to open or close any one of the multiple channels 10, just as the door 2 (not shown) sends a command to the security door 9.

[0059] Next, use Figure 4 The first variation of the access control system will be explained.

[0060] Figure 4 This is a block diagram of a first variation of the access control system using the access control device in Implementation Method 1.

[0061] like Figure 4 As shown, in the access control system, multiple camera devices 11 are installed inside the building. One of the multiple camera devices 11 captures... Figure 4 The internal region 1a and the external region 1b are not shown in the figure. In the first variation of embodiment 1, the camera device 11 that captures the internal region 1a and the external region 1b among the plurality of camera devices 11 will be described.

[0062] Upon receiving an instruction from the access control device 3, the camera device 11 detects the location of the moving body 5 based on the captured image. Once the location of the moving body 5 is detected, the camera device 11 generates second location information for the moving body 5, including information about the time of detection, and sends it to the access control device 3.

[0063] In the access control device 3, when the receiving unit 7 receives a first request notification or report notification from the mobile body 5, the authentication unit 8 determines the camera device 11 installed at the location corresponding to the first request notification or report notification. The authentication unit 8 then sends an instruction to the camera device 11 to transmit second location information.

[0064] Then, the receiving unit 7 receives the second position information of the mobile body 5 from the camera device 11. In this case, the authentication unit 8 determines whether the first position information and the second position information of the mobile body 5 match. Specifically, the authentication unit 8 calculates the difference between the first position shown by the first position information and the position shown by the second position information. If the value of the difference is less than a predetermined threshold, the authentication unit 8 determines that the first position information and the second position information match. If the authentication unit 8 determines that the first position information and the second position information match, and determines that the first position of the mobile body 5 when the first request notification or the report notification was sent is inside the internal authentication area 4a or the external authentication area 4b, the authentication unit 8 performs the authentication operation for the first request notification or the report notification.

[0065] Next, use Figure 5 An example of the actions taken by the access control device 3 when it receives a request notification will be explained.

[0066] Figure 5 This is a flowchart illustrating the outline of the operation of the first variant of the access control device in Embodiment 1.

[0067] like Figure 5 As shown, in step S001, the access management device 3 receives the first request notification from the mobile body 5.

[0068] Then, the action of step S002 is performed. In step S002, the access control device 3 sends a command to the camera device 11 to send the second location information.

[0069] Then, step S003 is performed. In step S003, the access control device 3 receives the second location information. The access control device 3 determines whether the first location information and the second location information match.

[0070] If the first location information and the second location information are determined to match in step S003, the entry / exit management device 3 proceeds to step S004. In step S004, the entry / exit management device 3 determines whether the first location of the moving body 5 is inside the internal authentication area 4a or the external authentication area 4b.

[0071] If, in step S004, it is determined that the first position of the moving body 5 is inside the internal authentication area 4a or the external authentication area 4b, the entry / exit management device 3 proceeds to step S005. In step S005, the entry / exit management device 3 performs the authentication action for the first request notification. Then, the entry / exit management device 3 terminates its operation.

[0072] If, in step S003, it is determined that the first location information and the second location information do not match, or if, in step S004, it is determined that the first location of the moving body 5 is not inside the internal authentication area 4a and the external authentication area 4b, the entry / exit management device 3 terminates its operation.

[0073] According to the first variation of Embodiment 1 described above, the camera device 11 generates second location information based on information obtained from capturing images of the moving body 5 when it sends the first request notification or report notification. The access control device 3 determines whether the second location information of the moving body 5 received from the camera device 11 matches the first location information. Therefore, it is possible to detect that the first location information is appropriate. As a result, security is improved.

[0074] Alternatively, two or more camera devices 11 can be installed. For example, one of the two camera devices 11 can film the internal area 1a. The other of the two camera devices 11 can film the external area 1b.

[0075] Alternatively, the access control device 3 may also have the function of generating second location information of the moving body 5 based on the information captured by the camera device 11. In this case, this function can also send the second location information to the receiving unit 7.

[0076] Next, use Figure 6 The second variation of the access control system will be explained.

[0077] Figure 6 This is a block diagram of a second variation of the access control system using the access control device in Implementation Method 1.

[0078] like Figure 6 As shown, in a second variation of the access control system, a beacon device 12 is disposed around the perimeter of the door 2. The beacon device 12 is configured to detect the position of the moving body 5 based on a signal from a transmitter disposed on the moving body 5.

[0079] In the second variation, the mobile unit 5 sends a first request notification or a report notification containing information including a one-time password to the access control device 3. At this time, the mobile unit 5 transmits a signal containing the one-time password from its transmitter. Upon receiving the first request notification or report notification, the authentication unit 8 sends information to the beacon device 12 that corresponds the one-time password information with the instruction to send second location information.

[0080] Upon receiving the instruction, beacon device 12 determines whether it has received a signal containing information of a one-time password corresponding to the instruction. If it determines that it has received a signal containing the one-time password, beacon device 12 generates second location information indicating the location where the signal exists. Then, beacon device 12 sends the second location information to access control device 3.

[0081] When the access control device 3 receives the second location information from the beacon device 12, it performs the same operation as in the first variant.

[0082] According to the second variation of Embodiment 1 described above, the access control device 3 determines whether the second location information of the moving body 5 received from the beacon device 12 matches the first location information. Therefore, it is possible to detect that the first location information is valid. As a result, security is improved.

[0083] Next, use Figure 7 The third variation of the access control system will be explained.

[0084] Figure 7 This is a block diagram of a third variation of the access control system using the access control device in Implementation Method 1.

[0085] like Figure 7 As shown, in the third variation of the access control system, the path history storage device 13 and the path management device 14 are located inside the building.

[0086] The path history storage device 13 stores the historical information of the path moved by the moving body 5.

[0087] The path management device 14 receives location information from the mobile body 5 at predetermined intervals. The path management device 14 generates historical information about the path traveled by the mobile body 5 at predetermined intervals and stores it in the path history storage device 13. Upon receiving an instruction from the entry / exit management device 3 to send the historical information of the mobile body 5, the path management device 14 sends the latest historical information of the mobile body 5 stored in the path history storage device 13 to the entry / exit management device 3.

[0088] In the third variation of the access control device 3, when the mobile body 5 receives the first request notification or report notification, the authentication unit 8 sends an instruction to the route management device 14 to send the historical information of the mobile body 5. When the receiving unit 7 receives the historical information from the route management device 14, the authentication unit 8 determines whether the first location information received from the mobile body 5 matches the historical information.

[0089] Specifically, for example, the authentication unit 8 calculates the shortest predicted travel time from the latest position of the moving body 5 shown in the historical information to the first position. The authentication unit 8 calculates the predicted arrival time by adding the predicted travel time to the time when the historical information was generated. If the current time is the same as or before the predicted arrival time, the authentication unit 8 determines that the first position information and the historical information match. If the current time is after the predicted arrival time, the authentication unit 8 determines that the first position information and the historical information do not match.

[0090] If the authentication department 8 determines that the first information and the historical information match, it will perform the authentication action of the first request notification or the report notification.

[0091] Next, use Figure 8 An example of the action taken by the access control device 3 to determine whether the first location information received from the mobile body 5 matches the historical information will be explained.

[0092] Figure 8 This is a flowchart outlining the operation of the third variation of the access control device in Embodiment 1.

[0093] like Figure 8 As shown, in step S101, the access management device 3 receives the first request notification from the mobile body 5.

[0094] Then, step S102 is performed. In step S102, the entry / exit management device 3 sends an instruction to the path management device 14 to send historical information.

[0095] Then, step S103 is performed. In step S103, the access control device 3 receives historical information. The access control device 3 determines whether the first location information and the historical information match.

[0096] If, in step S103, the first location information and historical information are determined to match, the access control device 3 performs the actions following step S104. In steps S104 and S105, the access control device 3 performs the same actions as those performed in steps S004 and S005 of the first variation of Embodiment 1. Then, the access control device 3 terminates its operation.

[0097] If the first location information and historical information are determined to be mismatched in step S103, the entry / exit management device 3 will terminate the operation.

[0098] According to the third variation of Embodiment 1 described above, the access management device 3 determines whether the historical information received from the path management device 14 matches the first location information. Therefore, the appropriateness of the first location information can be determined. Alternatively, by considering the first location information as accurate information, the appropriateness of the historical information can be determined.

[0099] Alternatively, the path history storage device 13 can also be located inside the path management device 14.

[0100] Alternatively, the route management device 14 can also be installed in a building different from the building where the management zone 1 is located.

[0101] Next, use Figure 9 An example of the hardware constituting the access control device 3 will be explained.

[0102] Figure 9 This is a hardware structure diagram of the control device for the elevator system in Implementation Method 1.

[0103] The functions of the access control device 3 can be implemented by a processing circuit. For example, the processing circuit has at least one processor 100a and at least one memory 100b. For example, the processing circuit has at least one piece of dedicated hardware 200.

[0104] In the case where the processing circuit has at least one processor 100a and at least one memory 100b, the functions of the access management device 3 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is referred to as a program. At least one of the software and firmware is stored in at least one memory 100b. The at least one processor 100a reads and executes the program stored in the at least one memory 100b, thereby implementing the functions of the access management device 3. The at least one processor 100a is also referred to as a central processing unit, processing device, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, a disk, floppy disk, optical disk, high-density disk, mini-disk, DVD, etc.

[0105] When the processing circuit has at least one dedicated hardware 200, the processing circuit is implemented, for example, by a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the access control device 3 is implemented by a separate processing circuit. For example, each function of the access control device 3 is implemented uniformly by a processing circuit.

[0106] Regarding the various functions of the access control device 3, some can be implemented by dedicated hardware 200, and others by software or firmware. For example, the function of sending open or closed commands to the door 2 can be implemented by the processing circuitry of the dedicated hardware 200, while functions other than sending open or closed commands to the door 2 can be implemented by at least one processor 100a reading and executing programs stored in at least one memory 100b.

[0107] Thus, the processing circuit implements the various functions of the access management device 3 through hardware 200, software, firmware, or a combination thereof.

[0108] Although not illustrated, the functions of the path management device 14 can be implemented by the same processing circuit that implements the functions of the access management device 3.

[0109] Implementation Method 2

[0110] Figure 10 This is a block diagram of an access control system using the access control device in Embodiment 2. Furthermore, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0111] exist Figure 10 In the illustrated embodiment 2, the management area 1 is divided into an internal area 1c, an internal area 1d, and an external area 1e. Door 2a is provided between the internal area 1c and the external area 1e as one of several candidate entrance / exit devices. Door 2b is provided between the internal area 1d and the external area 1e as one of several candidate entrance / exit devices. Door 2b is adjacent to door 2a. For example, the direction in which door 2b faces is perpendicular to the direction in which door 2a faces.

[0112] External authentication area 15a corresponds to door 2a. External authentication area 15a is located around door 2a in external zone 1e. External authentication area 15b corresponds to door 2b. External authentication area 15b is located around door 2b in external zone 1e. A portion of external authentication area 15b overlaps with a portion of external authentication area 15a. Duplicate authentication area 15c is the area where external authentication area 15a and external authentication area 15b overlap.

[0113] In embodiment 2, for example, the moving body 5 is configured to use a geomagnetic sensor to generate first directional information indicating how many degrees the direction is relative to the north.

[0114] When the mobile body 5 needs to enter the internal zone 1c from the external zone 1e, it moves to the inside of the external authentication zone 15a, i.e., the inside of the repeat authentication zone 15c. The mobile body 5 generates its own third position information and first direction information in the repeat authentication zone 15c. Then, the mobile body 5 sends information to the access control device 3, which includes the identification information of the mobile body 5 but not the identification information of the door 2a, and matches the third position information with the first direction information.

[0115] Upon receiving the second request notification, the third location information, and the first direction information, the access control device 3 determines, based on the third location information and the first direction information, that the door requested for passage by the moving body 5 in doors 2a and 2b is door 2a. Then, the access control device 3 performs an authentication operation related to the determined second request notification for door 2a.

[0116] Next, use Figure 11 The entry and exit management device 3 will be explained.

[0117] Figure 11 This is a block diagram of the access management system using the access management device in Implementation Method 2.

[0118] like Figure 11 As shown, the access control device 3 includes a determination unit 16. When the receiving unit 7 receives a second request notification, the determination unit 16 retrieves device information from the storage unit 6. Based on the device information and information that corresponds to the third position information and the first direction information received by the receiving unit 7, the determination unit 16 determines the door through which the mobile body 5 requests passage. Specifically, the determination unit 16 determines the door that exists in the direction indicated by the first direction information from the third position shown by the third position information as the door through which the mobile body 5 requests passage.

[0119] If the authentication unit 8 determines the door that the mobile body 5 requests to pass through, it performs the authentication operation of the second request notification. At this time, the authentication unit 8 determines whether the mobile body 5 has the authority to pass through the determined door.

[0120] According to Embodiment 2 described above, the access control device 3 includes a determination unit 16. The access control device 3 determines the access point requested by the mobile body 5 from among a plurality of candidate access points based on third position information and first direction information. Therefore, for a mobile body 5 that does not have identification information for the requested access point, the access point that the mobile body 5 wishes to access can be determined. For example, if a delivery robot arriving at the building for the first time has permission to access an access point but does not have identification information for that access point, the delivery robot cannot access that access point. By having the determination unit 16, the access control device 3 enables the delivery robot to pass. As a result, convenience is improved.

[0121] In addition, the moving body 5 can also use devices other than geomagnetic sensors to generate directional information.

[0122] Next, use Figure 12 A variation of Implementation Method 2 will be described.

[0123] Figure 12 This is a block diagram of a modified access control system using the access control device in Implementation Method 2.

[0124] like Figure 12 As shown, multiple camera devices 11 are installed in the access control system. Figure 12 The image shows one of a plurality of camera devices 11. One of the plurality of camera devices 11 captures... Figure 12 The external area 1e (not shown) is shown in the diagram. Multiple camera devices 11, upon receiving instructions from the access control device 3, detect the direction of the moving body 5 based on the captured images. Upon detecting the direction of the moving body 5, each camera device 11 generates second direction information for the moving body 5, including information about the time of detection, and sends it to the access control device 3.

[0125] In a modified example, the moving body 5 does not generate first direction information. The moving body 5 sends information to the access control device 3 that matches a second request notification (which does not include identification information for door 2a) with third location information.

[0126] In the access control device 3, when the receiving unit 7 receives information that corresponds to the second request notification and the third location information, the determining unit 16 determines, based on the third location information, the camera device 11 among the plurality of camera devices 11 that is located at a place where the moving body 5 that sent the second request notification exists. The determining unit 16 then sends an instruction to the camera device 11 to send the second direction information.

[0127] When the receiving unit 7 receives the second direction information from the camera device 11, the determining unit 16 determines the door that the mobile body 5 requests to pass through based on the equipment information, the third position information received by the receiving unit 7 from the mobile body 5, and the second direction information received by the receiving unit 7 from the camera device 11.

[0128] According to a variation of Embodiment 2 described above, the access control device 3 receives second direction information from the camera device 11. Therefore, even when the moving body 5 does not have a device for detecting direction, it is possible to determine the entrance / exit device that the moving body 5 requests to pass through. As a result, the access control system can be applied to various moving bodies 5.

[0129] Implementation Method 3

[0130] Figure 13 This is a block diagram of an access control system using the access control device in Embodiment 3. Furthermore, parts that are identical or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0131] exist Figure 13 In the access control system of Embodiment 3 shown, the service management device 17 is installed inside the building. The service management device 17 is owned by the service operator providing services using the mobile device 5. The service operator sets information on the service content of the mobile device 5, such as delivery and cleaning, on the service management device 17. The service management device 17 is configured to accept service requests from service users.

[0132] The mail dissemination device 18 is installed inside the building where the access control device 3 is located. Upon receiving a notification instruction from the access control device 3, the mail dissemination device 18 sends an email to the building manager containing the content of the notification instruction.

[0133] Upon accepting a service request, the service management device 17 generates action instruction information corresponding to the service request. Based on the action instruction information, the service management device 17 generates action information to instruct the mobile body 5. The service management device 17 then sends information to the mobile body 5 that associates the action information with the instruction to perform the service. For example, upon receiving the instruction, the mobile body 5, based on the corresponding action information, begins to... Figure 11 The outer region 1b (not shown) moves towards the inner region 1a. The moving body 5 moves from... Figure 11 The external authentication area 15a (not shown) sends information to the access management device 3, which corresponds to the first request notification containing the identification information of the door 2, the identification information of the mobile body 5, and the action information received from the service management device 17.

[0134] In the access control device 3 of embodiment 3, the authentication unit 8 determines, based on the information received from the mobile body 5, whether the mobile body 5 has a reason to pass through the gate 2 using a first determination method or a second determination method.

[0135] In the first determination method, when the receiving unit 7 receives information corresponding to the first request notification from the mobile body 5, the authentication unit 8 determines whether the information contained in the information is complete. For example, if the information contains identification information of the mobile body 5, identification information of the door 2, and action information, the authentication unit 8 determines that the information is complete. If the authentication unit 8 determines that the information is complete, it sends an instruction to the service management device 17 to send action instruction information corresponding to the mobile body 5.

[0136] When the receiving unit 7 receives action instruction information, the authentication unit 8 determines whether the action instruction information matches the action information received from the corresponding mobile body 5. Specifically, the authentication unit 8 determines whether the service content information, destination information, exit time information, and movement path information contained in the action information match the action instruction information. If the authentication unit 8 determines that the action instruction information and the action information match, it determines that the mobile body 5 has a reason to pass through the gate 2. In this case, the authentication unit 8 performs the authentication action of the first request notification corresponding to the action information.

[0137] In the second determination method, similar to the first determination method, the authentication unit 8 sends an instruction to the service management device 17 to send action instruction information. Upon receiving the action instruction information, the authentication unit 8 generates information indicating the permitted entry period and denied entry period for the mobile body 5 indicated by the action instruction information. Based on the received identification information of the mobile body 5 and the information indicating the permitted entry / exit period and denied entry / exit period, the authentication unit 8 determines whether it is a time when the mobile body 5 is permitted to enter or exit. If the authentication unit 8 determines that it is a time when the mobile body 5 is permitted to enter or exit, it determines that the mobile body 5 has a reason to pass through the gate 2. In this case, the authentication unit 8 performs an authentication operation corresponding to the identification information of the mobile body 5, sending a first request notification.

[0138] In addition, the access control device 3 also has an access history generation unit 19 and a notification unit 20.

[0139] When the authentication unit 8 authenticates that the mobile device 5 has entered the internal authentication area 4a from the external authentication area 4b, the entry / exit history generation unit 19 causes the storage unit 6 to store entry / exit history information indicating that the mobile device 5 has entered. When the authentication unit 8 authenticates that the mobile device 5 has exited from the internal authentication area 4a to the external authentication area 4b, the entry / exit history generation unit 19 adds information indicating that the mobile device 5 has exited to the entry / exit history information of the mobile device 5 stored in the storage unit 6.

[0140] When the scheduled exit time indicated by the action information received from the mobile device 5 is reached, the notification unit 20 determines whether the mobile device 5 is exiting based on the entry / exit history information stored in the storage unit 6. If the notification unit 20 determines that the mobile device 5 has not exited when the scheduled exit time is reached, it sends an instruction to the mail dissemination device 18 to notify it of this.

[0141] Next, use Figure 14 and Figure 15 The service management device 17 explains the action instruction information received by the user and the information generated by the access management device 3.

[0142] Figure 14 This is a diagram showing the action instruction information generated by the service management device of the access management device in application implementation 3. Figure 15 This is a diagram showing the information on permitted entry / exit periods and denied entry / exit periods generated by the entry / exit management device in Embodiment 3.

[0143] like Figure 14 As shown, the action instruction information is information that maps together the information of the "principal", the "merchant", the "content of the request", the "destination", the "service provision time" and the "use of the mobile body".

[0144] The "Consignor" information indicates the user of the service accepted by the service management device 17. The "Merchant" information indicates the provider of the service. The "Consignment Content" information indicates the type of service content. The "Destination" information indicates the location where the mobile body 5 moves during the service. The "Service Provision Time" information indicates the time period during which the mobile body 5 performs the service. The "Using Mobile Body" information indicates the identification information of the mobile body 5 performing the service.

[0145] For example, in the action instruction information of service 001, mobile body 5 with the identification information of M01 delivers luggage to room R01 around 13:00.

[0146] For example, in the action instruction information of service 002, the mobile body 5 with the identification information of M02 cleans room R02 and room R03 between 9:00 and 10:00.

[0147] like Figure 15 As shown, the information on permitted and denied entry / exit periods is information that maps together the information on "use of mobile vehicle," "object zoning," "time period," and "entry / exit permitted." Furthermore, the information on permitted and denied entry / exit periods corresponds to... Figure 13 The action instructions shown are as follows.

[0148] The "Object Zone" information refers to the information of the internal zone 1a that becomes an object. The "Time Period" information refers to the time period from a certain moment to another moment. The "Entry / Exit Permission" information refers to whether entry or exit of the mobile body 5 relative to the internal zone 1a that becomes an object is permitted or denied during a certain time period.

[0149] For example, in the information regarding permitted and denied entry / exit times for service 001, mobile body 5 with identification information M01 is permitted to enter and exit the internal zone 1a of S01 containing room R01 during the period from 12:45 to 13:15, around 13:00. Mobile body 5 is denied entry and exit from the internal zone 1a of S01 before 12:45 and after 13:15.

[0150] For example, in the information regarding permitted and denied entry / exit times for Service 002, mobile body 5, possessing the identification information of M02, is permitted to enter the internal zone 1a of S02, which contains rooms R02 and R03, around 9:00, specifically between 8:45 and 9:15. In the information regarding permitted and denied entry / exit times for Service 002, mobile body 5 is permitted to exit from the internal zone 1a of S02 between 9:45 and 10:15. M02 is denied entry outside of the 8:45-9:15 timeframe. M02 is denied exit outside of the 9:45-10:15 timeframe.

[0151] Next, use Figure 16 An example of the actions performed on the access control device 3 will be explained.

[0152] Figure 16 This is a flowchart illustrating the outline of the operation of the access control device in Embodiment 3.

[0153] like Figure 16 As shown, in step S201, the access management device 3 receives the first request notification from the mobile body 5.

[0154] Then, the action S202 is performed. In step S202, the entry / exit management device 3 determines whether the information received from the moving body 5 is sufficient.

[0155] If it is determined in step S202 that there is no insufficient information, the access management device 3 proceeds to step S203. In step S203, the access management device 3 sends an instruction to the service management device 17 to send action instruction information.

[0156] Then, step S204 is performed. In step S204, the access control device 3 determines whether the moving body 5 has a reason to pass through the door 2 based on the action instruction information.

[0157] If a reason for passage is determined in step S204, the access control device 3 proceeds to step S205. In step S205, the access control device 3 performs an authentication operation on the first request notification received from the mobile body 5.

[0158] Then, the entry / exit management device 3 ends its operation.

[0159] If, in step S202, it is determined that the received information is insufficient, or if, in step S204, it is determined that the mobile body 5 has no reason to pass through door 2, the access control device 3 performs the action in step S206. In step S206, the access control device 3 rejects the authentication of the mobile body 5. The access control device 3 sends a message indicating that authentication has been rejected to the mobile body 5. Then, the access control device 3 terminates its operation.

[0160] Next, use Figure 17 An example of the action of the access control device 3 causing the mail publishing device 18 to publish mail will be explained.

[0161] Figure 17 This is a flowchart illustrating the outline of the operation of the access control device in Embodiment 3.

[0162] exist Figure 17 In step S301, if the access control device 3 determines that the mobile body 5 has the right to pass, it begins the actions following step S301. In step S301, the access control device 3 generates and stores access history information.

[0163] Then, step S302 is performed. In step S302, the access control device 3 monitors the predetermined exit time of the mobile body 5 based on the access history information. Specifically, the access control device 3 determines whether the predetermined exit time of the mobile body 5 has passed.

[0164] If it is determined in step S302 that the predetermined exit time of the moving body 5 has not passed, the entry and exit management device 3 repeatedly performs the action of step S302.

[0165] If, in step S302, it is determined that the predetermined exit time for the mobile body 5 has elapsed, the access management device 3 performs the action in step S303. In step S303, the access management device 3 sends an instruction to the mail dissemination device 18, informing it that the predetermined exit time for the mobile body 5 has elapsed.

[0166] According to Embodiment 3 described above, the access control device 3 determines whether the mobile body 5 has a reason to pass through the access point based on the action information received from the mobile body 5. Therefore, it can determine that the permissions possessed by the mobile body 5 are legitimate. As a result, security is improved. Specifically, for example, the mobile body 5 may be granted permission to pass through a certain access point from multiple users X, Y, and Z. Without the access control device 3 shown in Embodiment 3, the mobile body 5, upon receiving an instruction from user W, could improperly pass through the access point using any permissions granted by users X, Y, and Z. In this case, security becomes a problem. The access control device 3 in Embodiment 3 can determine, based on the action information, that the mobile body 5, which sent a first request notification according to the instruction from user W, has no reason to pass. As a result, security is improved.

[0167] Furthermore, the access control device 3 determines whether the mobile body 5 has a reason to pass based on the action instruction information received from the service management device 17 and the action information received from the mobile body 5. Therefore, it can more accurately determine whether the mobile body 5 has a reason to pass. As a result, security is improved.

[0168] Furthermore, the access control device 3 has a notification unit 20. If the mobile body 5 fails to exit the internal zone 1a after the predetermined exit time, the access control device 3 notifies the administrator. Therefore, for example, if the mobile body 5 malfunctions and cannot move, the administrator can respond to the malfunction quickly. Moreover, if the mobile body 5 is improperly operated after passing through the entrance / exit device and performs actions different from the intended one, the administrator can be aware that the mobile body 5 is performing actions different from the intended one. As a result, security is improved.

[0169] Alternatively, the service management device 17 may be installed in a building different from the building where the management zone 1 is located and the building where the access management device 3 is located.

[0170] Additionally, the service management device 17 can also generate information on the permitted entry period and denied entry period for the mobile body 5 based on the action instruction information. In this case, the service management device 17 can also send the corresponding permitted entry period and denied entry period information for the mobile body 5 to the access management device 3 instead of the action instruction information. The access management device 3 can also make a determination based on the second determination method based on the permitted entry period and denied entry period information.

[0171] Next, use Figure 18 A variation of the access control system in Implementation 3 will be described.

[0172] Figure 18 This is a block diagram of a modified access control system using the access control device in Implementation Method 3.

[0173] like Figure 18 As shown, a path management device 14 is provided in the access management system of the modified embodiment 3.

[0174] In the access control device 3, the authentication unit 8 uses the third determination method to determine whether the moving body 5 has a reason to pass through the gate 2.

[0175] In the third determination method, when the receiving unit 7 receives information corresponding to the first request notification from the mobile body 5, the authentication unit 8, similar to the first determination method, determines whether the information contained in the information is complete. If the authentication unit 8 determines that the information is complete, it sends an instruction to the service management device 17 to send the action instruction information corresponding to the mobile body 5. At this time, the authentication unit 8 sends an instruction to the route management device 14 to send the historical route information related to the mobile body 5.

[0176] Then, based on the same determination method as the first determination method, the authentication unit 8 determines whether the historical path information of the mobile body 5 matches the action instruction information. Specifically, the authentication unit 8 estimates the shortest path for performing the service content shown in the action instruction information received by the receiving unit 7. The authentication unit 8 determines whether the historical information received by the receiving unit 7 matches the shortest path. If the authentication unit 8 determines that the historical information of the mobile body 5 matches the shortest path, and also determines that the action instruction information and the action information are consistent as in the first determination method, the authentication unit 8 determines that the mobile body 5 has a reason to pass through the gate 2. In this case, the authentication unit 8 performs the authentication operation for the first request notification received from the mobile body 5.

[0177] According to the variation of Implementation 3 described above, the access control device 3 determines whether historical information and action information match. Therefore, it is possible to more accurately determine the appropriateness of action information. For example, the access control device 3 can detect that the mobile body 5 takes unreasonable actions towards supported service content.

[0178] Alternatively, the authentication unit 8 may, instead of the first determination method, determine, based on the same determination method as the second determination method, whether the historical information of the path of the mobile body 5 matches the action instruction information. In this case, the authentication unit 8 may also determine that the mobile body 5 has a reason to pass through the gate 2 if it determines that the historical information of the mobile body 5 matches the shortest path and that it is within a period when the mobile body 5 is permitted to enter or exit.

[0179] Implementation Method 4

[0180] Figure 19 This is a top view of the management area of ​​the access control device in Embodiment 4. Additionally, parts that are the same as or equivalent to those in Embodiment 1 are labeled with the same reference numerals. Descriptions of these parts are omitted.

[0181] In the access control system of embodiment 4, security doors 9a and 9b are located between the internal zone 1a and the external zone 1b. Security door 9a is located next to security door 9b. A common internal authentication area 4a and an external authentication area 4b are provided for security doors 9a and 9b.

[0182] Waiting areas 21a and 21b are located in the external authentication area 4b via access control device 3. Waiting areas 21a and 21b are located near security door 9a. Waiting area 21a is closer to security door 9a than waiting area 21b. Waiting area 21a is given a higher priority than waiting area 21b.

[0183] When a person needs to move from the internal authentication area 4a to the external authentication area 4b to pass through security door 9a, they hold their ID card up to security door 9a. If the access control device 3 determines that the person has access rights based on the information on the ID card, it sends an open command to security door 9a. Security door 9a opens.

[0184] At this time, the mobile body 5 sends a first request notification for passage through security gate 9a from the external authentication area 4b to the access control device 3. If the access control device 3 determines that the mobile body 5 has permission to pass through security gate 9a when the person has not passed through it, it determines that security gate 9a is in use and detects that security gate 9a is inaccessible. In this case, as an alternative action, the access control device 3 sends a waiting instruction to the mobile body 5 at the designated waiting area 21a. The mobile body 5 then moves to the waiting area 21a.

[0185] Then, the person passes through security door 9a. After a predetermined time has elapsed since the access control device 3 sent a standby command to the mobile body 5, it sends a command to the mobile body 5 to perform the action of passing through security door 9a. At this time, the access control device 3 sends an opening command to security door 9a. The mobile body 5 then passes through security door 9a.

[0186] Next, use Figure 20 The entry and exit management device 3 will be explained.

[0187] Figure 20 This is a block diagram of the access management system using the access management device in implementation method 4.

[0188] like Figure 20 As shown, the access control device 3 has a passability detection unit 22 and an instruction unit 23.

[0189] The accessibility detection unit 22 receives information indicating the status of the access control device from the access control device. If the accessibility detection unit 22 determines that the access control device is in use or cannot be used for an extended period, it detects that the access control device is currently inaccessible. Specifically, if the authentication unit 8 determines that the mobile body 5 has the right to pass through the access control device, the accessibility detection unit 22 detects whether the access control device is in use. For example, if the access control unit 22 determines that the access control device is in use if it was opened to allow passage for a mobile body or person other than the mobile body 5 and then not closed, it determines that the access control device is in use.

[0190] If the accessibility detection unit 22 determines that the access control device is not in use, it then determines whether the access control device is in a state where it cannot be used for an extended period of time. Specifically, for example, if the accessibility detection unit 22 detects a malfunction in the access control device, it determines that the access control device is in a state where it cannot be used for an extended period of time. For example, if the accessibility detection unit 22 detects an obstacle in the route through which the access control device is used, it determines that the access control device is in a state where it cannot be used for an extended period of time.

[0191] If the accessibility detection unit 22 determines that an access control device is in use, it determines whether there are other access control devices that can be used in place of that access control device. Specifically, for example, if the accessibility detection unit 22 detects that a security door 9b next to security door 9a can be used, it determines that there are other access control devices.

[0192] If the accessibility detection unit 22 determines that there is another access device, the command unit 23 sends an opening command to the security door 9b, which is the other access device. If the accessibility detection unit 22 determines that there is another access device, the command unit 23 sends an instruction to the moving body 5 to allow it to pass through the other access device.

[0193] If the accessibility detection unit 22 determines that there are no other access devices, the instruction unit 23 calculates the time until the access device becomes usable. For example, if a person wants to pass through security door 9a, the instruction unit 23 calculates the time until it becomes usable as 5 seconds. For example, if another moving body 5 wants to pass through security door 9a, the instruction unit 23 calculates the time until it becomes usable as 30 seconds longer than in the case of a person.

[0194] After calculating the time until the facility becomes available, the command unit 23 assigns one or more waiting areas to the mobile body 5 for standby. For example, the command unit 23 assigns the highest-priority waiting area from one or more waiting areas that are not currently assigned to any mobile body 5 to the mobile body 5. The command unit 23 sets the assigned waiting area to be in use. The command unit 23 sends a command to the mobile body 5 to move to the assigned waiting area. Then, after the calculated time until the facility becomes available has elapsed, the command unit 23 sends a command to the mobile body 5, which received the command to move to the waiting area, to allow it to pass through the entrance / exit device. At this time, the command unit 23 sends an open command to the entrance / exit device.

[0195] If the instruction unit 23 determines that the entrance / exit device is in a state where it cannot be used for a long time, it will notify the manager of the entrance / exit device that the entrance / exit device is in a state where it cannot be used for a long time.

[0196] If the command unit 23 determines that the entrance / exit device is in a state where it cannot be used for a long time, it uses the building map information stored in advance by the storage unit 6 to search for a detour route that does not pass through the entrance / exit device.

[0197] In the case of a detour route, the instruction unit 23 sends information about the detour route to the mobile body 5 and an instruction to move it along the detour route.

[0198] In the absence of a detour route, the command unit 23 sends a command to the moving body 5 to stop its action of passing through the entrance / exit device. For example, the command unit 23 may also send a command prompting the moving body to perform other actions along with the command to stop its action.

[0199] Next, use Figure 21 An example of the judgment made by the access control device 3 will be explained.

[0200] Figure 21 This is a diagram illustrating an example of the judgment made by the entry / exit management device in Embodiment 4.

[0201] like Figure 21 As shown, the access control device 3 determines the status of the entrance / exit device as indicated by "Status: Classification" and "Status: Reason".

[0202] As indicated by "Status: Reason", the access control device 3 detected that a person or other moving body 5 is passing through the access control device in the same or opposite direction as the moving body 5, which has sent the first request notification related to the access control device. The access control device 3 detected a malfunction in the access control device. The access control device 3 detected the presence of an obstacle obstructing passage through the access control device.

[0203] As indicated by "Status: Classification," the access control device 3 classifies the current status of the entrance / exit device based on "Status: Reason." If the "Status: Reason" indicates that a person or other moving object 5 is passing through the entrance / exit device, the access control device 3 detects "Status: Classification" as indicating that the entrance / exit device is in use. If the "Status: Reason" indicates that the entrance / exit device is malfunctioning or is obstructed, the access control device 3 determines "Status: Classification" as indicating that the entrance / exit device cannot be used for an extended period.

[0204] The access control device 3 estimates the "conditions / times at which it becomes usable" based on "Status: Classification" and "Status: Reason". When "Status: Classification" is "In Use", the access control device 3 estimates that the usable condition will be after the passage of a person or other moving object. When "Status: Classification" is "In Use", the access control device 3 calculates the standby time corresponding to the currently passing object. When "Status: Reason" is "Entrance / Exit Device Malfunction", the access control device 3 estimates that the usable condition will be after the entrance / exit device is repaired. When "Status: Reason" is "Obstacle Exists", the access control device 3 estimates that the usable condition will be after the obstacle is removed.

[0205] The access control device 3 provides "instructions for the moving body" based on "Status: Classification" and "Status: Reason". The access control device 3 also responds to the access control system based on "Status: Classification" and "Status: Reason".

[0206] Next, use Figure 22 An example of an action that the access control device 3 instructs the moving body 5 to perform a substitute action will be explained.

[0207] Figure 22 This is a flowchart illustrating the outline of the operation of the access control device in Embodiment 4.

[0208] The access control device 3 begins to operate upon receiving a first request notification from the mobile body 5 to pass through the security gate 9a.

[0209] like Figure 22 As shown, in S401, the access control device 3 determines whether the moving body 5 has the authority to pass through the security door 9a based on the first request notification during the authentication process.

[0210] If it is determined in step S401 that the moving body 5 does not have the authority to pass through the security door 9a, the entry and exit management device 3 ends its operation.

[0211] If it is determined in step S401 that the moving body 5 has the authority to pass through security door 9a, the access control device 3 performs action S402. In step S402, the access control device 3 determines whether security door 9a corresponding to the first request notification is in use.

[0212] If it is determined in step S402 that the safety door 9a is not in use, the access control device 3 proceeds to step S403. In step S403, the access control device 3 determines whether the safety door 9a is in a state where it cannot be used for an extended period of time.

[0213] If, in step S403, it is determined that the security door 9a is not in a state where it cannot be used for an extended period of time, the access control device 3 proceeds to step S404. In step S404, the access control device 3 sends an opening command to the security door 9a.

[0214] Then, the entry / exit management device 3 ends its operation.

[0215] If it is determined in step S402 that safety door 9a is in use, the access control device 3 proceeds to step S405. In step S405, the access control device 3 determines whether there is another safety door that can replace safety door 9a.

[0216] If it is determined in step S405 that a safety door replacing safety door 9a exists, the access control device 3 performs the action in step S406. In step S406, the access control device 3 sends an opening command to the other safety door replacing safety door 9a.

[0217] Then, the access control device 3 performs step S407. In step S407, the access control device 3 sends an instruction to the mobile body 5, which sent the first request notification, to pass through another security door that replaces security door 9a.

[0218] Then, the entry / exit management device 3 ends its operation.

[0219] If it is determined in step S405 that there is no other safety door to replace safety door 9a, the access control device 3 proceeds to step S408. In step S408, the access control device 3 calculates the time until safety door 9a becomes available.

[0220] Then, step S409 is performed. In step S409, the access control device 3 determines the waiting area to be assigned from one or more waiting areas corresponding to the security door 9a. The access control device 3 sends an instruction to the mobile body 5 that sent the first request notification to move to the assigned waiting area.

[0221] Then, the action of step S410 is performed. In step S410, the entry / exit management device 3 determines whether the state in which the mobile body 5 should be in the waiting area has been eliminated.

[0222] If it is determined in step S410 that the standby state has not been eliminated, the entry / exit management device 3 repeatedly performs the action of step S410.

[0223] If, in step S410, it is determined that the standby state has been eliminated, the access control device 3 performs the action in step S411. In step S411, the access control device 3 sends a command to the security door 9a to open it. The access control device 3 also sends a command to the moving body 5, which has been instructed to move to the waiting area, to pass through the security door 9a.

[0224] Then, the entry / exit management device 3 ends its operation.

[0225] If, in step S403, it is determined that the security door 9a is in a state where it cannot be used for an extended period of time, the access control device 3 performs the action in step S412. In step S412, the access control device 3 notifies the administrator that the security door 9a is in a state where it cannot be used for an extended period of time.

[0226] Then, step S413 is performed. In step S413, the entry / exit management device 3 determines whether there is a detour route.

[0227] If a detour route is determined to exist in step S413, the access control device 3 performs the action in step S414. In step S414, the access control device 3 sends information about the detour route and an instruction to move to the detour route to the mobile body 5 that sent the first request notification.

[0228] Then, the entry / exit management device 3 ends its operation.

[0229] If it is determined in step S413 that there is no detour route, the access control device 3 proceeds to step S415. In step S415, the access control device 3 sends an instruction to the mobile body 5 that sent the first request notification, ordering it to stop its action of passing through security gate 9a.

[0230] Then, the entry / exit management device 3 ends its operation.

[0231] According to Embodiment 4 described above, the access control device 3 includes a passability detection unit 22 and an instruction unit 23. When the access control device 3 detects that the entrance / exit device is in a state where a mobile body 5 with access rights cannot pass, it sends an instruction to the mobile body 5 to perform an alternative action. Therefore, for example, it is possible to instruct a mobile body 5, whose situation cannot be determined independently, to perform actions in an unstable state where the entrance / exit device cannot pass. That is, the access control device 3 can assist the movement of the mobile body 5. Suppose that without the access control device 3 of Embodiment 4, a mobile body 5, whose situation cannot be determined independently, might attempt to pass through an entrance / exit device in a state where it cannot pass. In this case, the mobile body 5 would unreasonably attempt to pass through the entrance / exit device, potentially damaging it. Furthermore, it might come into contact with other mobile bodies 5 that previously attempted to pass. By applying the access control device 3 of Embodiment 4, both the equipment and the mobile body 5 can be protected. Furthermore, in the event of the aforementioned malfunction, it is possible to prevent people from taking advantage of the malfunction to improperly pass through the entrance / exit device.

[0232] Furthermore, the access control device 3 sends an instruction to the mobile body 5 to wait at the designated waiting area for a specified time. Therefore, the mobile body 5 is able to wait in the order of passing through the access control device.

[0233] Furthermore, if the access control device 3 detects that the access point has been in a state where the mobile body 5 cannot pass through for an extended period, it sends a command to the mobile body 5 to stop its movement through the access point. Therefore, it is possible to prevent the mobile body 5 from waiting for an extended period at the access point. Additionally, for example, the mobile body 5 can cancel a task that should be performed through the access point and perform another task. As a result, the mobility efficiency of the mobile body 5 can be improved.

[0234] In addition, the access control device 3 can also determine the waiting area for the mobile body 5 based on the direction of movement of the person or other mobile body 5 when deciding on the waiting area.
