Summary of the Invention

Problems to be Solved by the Invention

[0004] The invention of Patent Document 1 is an invention for determining whether an outside person is taking suspicious actions based on determination conditions corresponding to the purpose of visit of the outside person stored in the storage device.

[0005] However, it is difficult to obtain the stay time determined as abnormal from the purpose of visit. For example, there is no guarantee that the meeting time of a visitor who enters the building to participate in a meeting will definitely end at the scheduled time, and the meeting may continue in another meeting room.

[0006] In addition, there is no guarantee that the repair of building facilities can be completed within a certain period of time. Therefore, there is a problem that it is difficult to say that suspicious behavior is taken uniformly just because the time of entry into the building is judged according to the determination conditions according to the purpose and the visitor has not left the building within the time determined by the determination conditions.

Means for Solving the Problems

[0007] The above problems are solved by an entrance and exit management system for managing the entry time of visitors to a building, which includes an entrance and exit management unit that detects a visitor when the visitor enters the building, accepts the input of the scheduled departure time, determines whether the visitor is permitted to enter, and accepts the departure time when the visitor leaves; a destination management unit that detects the arrival of the visitor at the destination within the building and determines whether it is a visitor; visitor history information that stores the determination time of the visitor determined by the entrance and exit management unit and the destination management unit; an abnormality detection unit that determines abnormality when the visitor has not left by the scheduled departure time based on the detection time of the visitor stored in the authentication history information; an extension processing unit that accepts the correction of the scheduled departure time and updates the visitor history information; and an output unit that outputs the visitor determined to be abnormal by the abnormality detection unit.

Effects of the Invention

[0008] The present invention can more accurately determine visitors who stay in the building longer than necessary.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings for explaining the embodiments, the same components are given the same names and reference numerals as much as possible, and the repeated explanations thereof are omitted.

[0011] The present invention is not limited to the embodiments described below, and includes various modifications and equivalent configurations within the scope of the appended claims. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and the present invention is not necessarily limited to those having all the configurations described.

[0012] In addition, the processing units and processing modules described in the embodiments may be realized in hardware by designing a part or all of them, for example, by using an integrated circuit, or may be realized in software by a processor interpreting and executing programs for realizing their respective functions.

[0013] The information described in the embodiments may be a table, a database (DB), or data stored in the main memory.

Embodiment

[0014] FIG. 1 is an example of a system configuration diagram in an embodiment of the present invention.

[0015] The entry / exit management system 1 is composed of a computer including a CPU (Central Processing Unit) 2, a main memory device 3, an external memory device 4 such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), an input / output unit 5, and the like.

[0016] In this embodiment, an example of configuring with a computer such as a PC (Personal Computer) will be described, but it may also be configured by using a cloud system in which computer resources are virtualized.

[0017] The entry / exit management system 1 is connected to the sensor / camera / authentication terminal 28 of the facility to be managed 6 via the network 11 to detect visitors. Which of the sensor, camera, and authentication terminal to use is determined based on the equipment already provided in the facility to be managed and the required security level.

[0018] In this embodiment, a method using a surveillance camera that is likely to be installed in the facility to be managed will be mainly described.

[0019] Also, the entry / exit management system 1 can refer to the entry / exit permit list 10 stored in the management center server 9 via the network 11 and determine a person who is permitted to enter the facility to be managed 6.

[0020] The entry / exit permit list 10 for which entry to the facility to be managed is permitted is stored in the management center server 9 on the cloud, and entry to the facility to be managed is permitted based on this information.

[0021] Furthermore, it is also connected to an elevator control device 7 that controls elevators such as elevators, can recognize that a visitor has used the elevator, and can obtain the time required for using the elevator.

[0022] The administrator can grasp the visits staying in the facility to be managed 6 via the network using the administrator terminal 8.

[0023] The main memory device 3 stores an abnormality detection unit 21, a destination management unit 23, an entry / exit management unit 24, and an extension processing unit 25 as software modules, and is executed by the CPU 2 with reference to tables and databases such as the visitor history information 26 and the movement time table 27 stored in the external memory device 4.

[0024] The movement tolerance time 22 is information indicating how much delay is allowed when the arrival of a visitor at the destination within the building is delayed. Since the movement tolerance time 22 varies greatly depending on the purpose of the visitor's visit, it is necessary to determine it for each purpose of the visitor's visit.

[0025] The result of the execution is output to the administrator terminal 8 etc. via the input / output unit 5. Although not shown in the system configuration diagram of FIG. 1, in a system that receives identification information from the visitor's smartphone by the sensor / authentication terminal 28 and performs authentication, the screen output by this system may be output to the visitor's smartphone via the input / output unit 5.

[0026] FIG. 2 shows an example of visitor history information in an embodiment of the present invention.

[0027] The visitor ID 31 for identifying the visitor, the face authentication information 32, the entry time 33, the scheduled arrival time at the destination 34, and the scheduled departure time 36 are stored in association with each other.

[0028] When a visitor enters the building, when the visitor is detected by a camera or the like, the input of the arrival time at the destination 35 and the departure time 37 is received, and the received schedule is registered. If the authentication of the visitor is not performed using a camera image, the face authentication information 32 may not be necessary. If the input of the purpose of the visitor's visit is requested at the time of entry, the consistency with the input scheduled arrival time at the destination and the scheduled departure time can be confirmed.

[0029] For example, it is registered that a visitor with the visitor ID BBBBBB entered the building at 13:30, is setting up WIFI in Room 302, and is scheduled to leave the building at 14:30. Since the departure time is not registered, it can be seen that this visitor is still in Room 302.

[0030] Figure 3 shows an example of the admission and exit permit list in an embodiment of the present invention.

[0031] The admission permit ID 40 and the admission permit face image 41 are stored in association with each other. In this embodiment, it is stored in the management center server 9 as the admission and exit permit list 10, but if it is not necessary to be shared among multiple buildings, it may be stored in the external storage device 4 of the access control system 1.

[0032] Figure 4 shows an example of the movement time table in an embodiment of the present invention.

[0033] A table storing the time (seconds) required to move between the current location 51 and the destination 52 is prepared according to the building structure.

[0034] This example is of a three-story building with elevators, having two rooms (A, B) on the first floor, three rooms (C, D, E) on the second floor, and three rooms (F, G, H) on the third floor.

[0035] The movement time is described as including the movement time from the current location to the elevator, the floor movement time by the elevator, and the movement time from the elevator to the destination. However, when the movement time by the elevator can be obtained from the elevator control device 7, by excluding the floor movement time by the elevator, an increase in the stay time within the facility due to the congestion of the elevator can be grasped.

[0036] Since the congestion situation of the elevator varies greatly depending on the time zone of use, by obtaining the actual time taken from the elevator control device 7, the validity of the visitor's stay time can be judged more accurately.

[0037] In this example, a small building is described as an example. However, in a large building complex consisting of multiple buildings, even if it is a movement on the same floor, there may be cases where one has to get off the elevator to the first floor, move to the building where the destination is located, and then board the elevator again to move to the destination floor. Therefore, if the time consistent with the building structure is not registered, it will deviate from the actual required movement time, so caution is necessary.

[0038] Figure 5 is an example of a flowchart showing the processing of the access control system in an embodiment of the present invention.

[0039] First, an admission process (S1) is performed to input the visitor's visitor ID, destination within the building, scheduled departure time, etc. The visitor ID is compared with the admitted visitor ID registered in the access permission list 10, and if it is registered, it is determined that the admission is permitted (S2).

[0040] Whether admission is permitted or not, a face image of the visitor may be obtained by a camera for face authentication, or the visitor ID may be read from a smartphone or ID card held by the visitor by a card reader for determination.

[0041] If admission is permitted, the door at the building entrance is unlocked to allow the visitor to enter the building (S3). When the visitor enters the building and reaches the destination within the building, a face image is obtained by a camera near the destination (S4).

[0042] When the abnormality detection unit 21 can determine that the face image is the face image of the visitor, the current time is registered in the destination arrival time 35 of the visitor history information 26 (S5).

[0043] If it is possible to install a card reader at the destination within the building, the visitor ID may be read by the card reader. However, if security standards permit, face authentication can be performed using the camera image of the surveillance camera, and there is no need to install a card reader.

[0044] Furthermore, the abnormality detection unit 21 determines the validity of the arrival time at the destination by comparing it with the scheduled arrival time at the destination (S6). Since there may be cases where the visitor cannot move within the time registered in the movement time table 27 depending on the walking speed of the visitor, the presence or absence of luggage, etc., it may be acceptable not to determine it as abnormal even if the time is later than the scheduled arrival time at the destination within the time predetermined by the movement allowance time 22.

[0045] By providing such a time, it is possible to avoid outputting a large number of alarms and burying important alarms. Also, if alarms occur frequently, by outputting information that the time registered in the movement time table 27 may be inappropriate, the movement time table 27 can be made more suitable for the facility to be managed.

[0046] When determining the validity of the arrival time at the destination and it is determined that the stay time is long (S7), it is determined as abnormal and the abnormality is notified to the management center server 9 and the administrator terminal 8 (S8).

[0047] The administrator using the management center server 9 and the administrator terminal 8 requests the visitor to correct the scheduled arrival time at the destination and performs an extension process (S9). At this time, a correction request may be output to a smartphone or the like held by the visitor.

[0048] Alternatively, it may be corrected using a terminal installed at the building entrance or the like where information was input at the time of entry.

[0049] If the stay time is not long in S7, or if the extension process is completed, it is determined whether a visitor is detected by a camera near the exit (S10). If it is not a camera near the exit, it returns to S4.

[0050] If a visitor is detected by a camera near the exit, the leaving time is registered in the visitor history information (S11). The validity of the time from entry to exit is determined by comparing it with the scheduled leaving time (S12). If the stay time is long, the abnormality determination unit determines it as abnormal and notifies the management center server 9 and the administrator terminal 8. If the stay time is not long, the process ends.

[0051] FIG. 6 is an example of a flowchart showing the entry process in an embodiment of the present invention.

[0052] In the entry process, a face image is acquired by a camera. If it is an apartment, the input of the building destination visit destination such as the room number and the purpose of the visit is received (S20), and an inquiry is made as to whether the corresponding person is at home with information indicating the visitor attached. When a response indicating that the person is at home is received from the visit destination, a display indicating that the person is at home is made (S21).

[0053] The visitor inputs the visit destination based on the display indicating that the person is at home, and the access control system receives it (S22). The destination management unit 23 outputs a scheduled arrival time plan for the destination based on the input visit destination and the purpose of the visit (S23).

[0054] Regarding the input of the visit destination, if it is a delivery by a courier service, it is conceivable to make more than 10 deliveries at a time. Therefore, if the visit destinations regarding the deliveries on the current day are received from the server of the courier service provider and only the home status of the received visit destinations is input, the burden on the visitor can be reduced.

[0055] The travel time is obtained by referring to the travel time table 27, the required time at the destination is obtained based on the purpose of the visit, and a plan for the scheduled arrival time 34 at the destination is created and output (S23).

[0056] Since the required time at the destination may vary greatly depending on the visitor's business, a correction of the scheduled arrival time 34 at the destination is received (S24).

[0057] The destination management unit 23 checks the corrected scheduled arrival time 34 at the destination and determines whether it is an abnormal time (S25). If it is not an abnormal time, the scheduled time in the visitor history information is registered (S27). When it is determined to be abnormal, after notifying the management center server 9 and the administrator terminal 8 (S26), the scheduled time in the visitor history information is registered.

[0058] The determination of whether it is abnormal is made by setting a predetermined allowable time for each purpose of the visit, and if it is not within the time, it is determined to be abnormal.

[0059] Figure 7 is an example of a flowchart showing the extension process in an embodiment of the present invention.

[0060] This is a process of requesting a modification of the scheduled time to the visitor when it is determined that the stay time of the visitor is long. First, the visitor history information is displayed (S40), and an input of the modified scheduled time is received (S41).

[0061] It is determined whether the input modified scheduled time is appropriate (S42). If it is appropriate, the scheduled time in the visitor history information is modified (S44). If it is determined to be abnormal, after notifying the management center server 9 and the administrator terminal 8 (S26), the scheduled time in the visitor history information is registered.

[0062] To determine whether it is appropriate, a predetermined allowable time is set for each purpose, and if it is not within that time, it is determined to be abnormal.

[0063] Figure 8 is an example of a screen for notifying a long - stay visitor in an embodiment of the present invention.

[0064] The screen for notifying a long - stay visitor is a screen for notifying the management center server 9 and the administrator terminal 8. It includes a building name column 61, a visitor column 62, an entry time column 63 in which the entry time and the scheduled departure time are displayed, and a final confirmation position column 64 indicating the position where the visitor was last confirmed.

[0065] When the visitor is performing the entry process with a smartphone or the like, it may be output to the screen of the visitor's smartphone to prompt the modification of the scheduled departure time.

[0066] Also, in this example, it is an example where the departure of the visitor is not confirmed even after the scheduled departure time has passed. However, when the visitor cannot be confirmed at the scheduled time at the destination within the building, the visitor and the unconfirmed destination within the building may be output.

[0067] Since the inability to confirm the destination within the building is likely to occur more frequently than passing the scheduled departure time, by displaying it in a manner different from the case of passing the scheduled departure time, such as changing the background color, it is possible to easily identify the screen that requires the administrator's response.

[0068] FIG. 9 is an example of a screen for correcting the scheduled time of visiting a destination within a building in an embodiment of the present invention.

[0069] The screen for correcting the scheduled time of visiting a destination within a building includes a building name column 71, a visitor column 72, a scheduled visit time column 73, and a correction button 74 for inputting and registering the scheduled correction time.

[0070] This screen is also a screen for notifying the management center server 9 and the administrator terminal 8. However, when a visitor is performing the entry process with a smartphone or the like, it can be output to the screen of the visitor's smartphone, and by prompting the correction of the scheduled departure time, the burden on the administrator can be reduced.

[0071] Also, the visitor does not need to move to the entrance where there is an input terminal for correcting the scheduled time.
