Embodiment 1.
Hereinafter, the entry / exit management system 1 of the first embodiment of the present application will be described. In the description of the drawings, the same parts or corresponding parts are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is an overall schematic view of the entry / exit management system 1 according to the first embodiment. In the first embodiment, an embodiment in which the entry / exit management system 1 is applied to the hospital 2 which is a facility is shown. The entry / exit management system 1 manages entry / exit of patients 3A to 3D (patient 3) who are monitored subjects in the hospital 2.

Patient 3 should be in hospital 2, and if patient 3 goes out of hospital 2, it needs to be searched. The search for the patient 3 who has gone out is performed by a hospital staff such as a security guard or a nurse at the hospital 2, or a notification target person such as a family member of the patient 3.

Patients 3A to 3D possess subject terminals 4A to 4D (subject terminals 4) assigned to each individual. The subject terminal 4 is a terminal that can be worn by the patient 3 and is capable of wireless communication. The target person terminal 4 is, for example, an IC tag, a non-contact card, or a smartphone. The subject terminal 4 is carried by the patient 3 by wrapping it around the patient 3's wrist, hanging it around the neck, putting it in a pocket of clothes, holding it in the hand, or the like. Each target person terminal 4 internally stores unique target person identification information. The target person identification information is unique information for each target person terminal 4 such as a numerical value, a character string, and a MAC address.

The hospital 2 is provided with doors 6A to 6D (doors 6), which are entrances and exits for the patient 3 to enter and exit. Reading units 11A to 11D (reading units 11) are installed in the vicinity of the door 6 to read the target person identification information of the target person terminal 4 possessed by the patient 3. By installing the reading unit 11 near the entrance / exit of the hospital 2, when the patient 3 enters and exits from the hospital 2, the reading unit 11 can read the target person identification information of the target person terminal 4 possessed by the patient 3. .. As a specific method of reading the target person identification information, for example, when the target person terminal 4 transmits the target person identification information by UHF (UltraHigh Frequency) radio waves, the reading unit 11 is provided with a function of receiving the UHF radio waves. The reading unit 11 can read the target person identification information from the radio waves received from the target person terminal 4. In addition to the entrance / exit of the hospital 2, the reading unit 11 may be provided inside the room of the inpatient who is the patient 3 and on the route to the entrance / exit of the hospital 2.

As shown in FIG. 1, the reading units 11A to 11D are installed in the vicinity of different doors 6A to 6D. Further, in the hospital 2, reading areas 5A to 5D (reading areas 5) in which the reading units 11A to 11D read the target person identification information are set. The reading unit 11A reads the reading area 5A, the reading unit 11B reads the reading area 5B, the reading unit 11C reads the reading area 5C, and the reading unit 11D reads the target person identification information of the target person terminal 4 existing inside the reading area 5D. Although the reading areas 5A to 5D do not overlap in FIG. 1, the reading areas 5A to 5D may partially overlap. Since the patient 3D does not exist in any of the reading areas 5A to 5D in FIG. 1, none of the reading units 11 can read the subject identification information of the subject terminal 4D.

The imaging units 12A to 12D (imaging unit 12) are installed in the vicinity of the reading unit 11 so as to acquire at least a part of the image of the reading area 5 of the reading unit 11. As shown in FIG. 1, the imaging unit 12A is installed in the vicinity of the reading unit 11A so as to image the reading area 5A of the reading unit 11A. Similarly, the imaging unit 12B is installed near the reading unit 11B, the imaging unit 12C is installed near the reading unit 11C, and the imaging unit 12D is installed near the reading unit 11D.

Notification destination terminals 7A to 7D (notification destination terminals 7) are installed in each reading area 5. The notification destination terminal 7 is a terminal capable of communicating with the notification unit 14 described later, includes a display capable of displaying an image of the patient 3, and notifies the absence of the patient 3. Although the notification destination terminal 7 is fixedly installed in the hospital 2 in FIG. 1, it may be carried by a person to be notified inside or outside the hospital 2.

Like the target person terminal 4, the notification destination terminal 7 internally stores unique notification destination identification information. The notification destination identification information is unique information for each notification destination terminal 7 such as a numerical value, a character string, and a MAC address, like the target person identification information of the target person terminal 4.

The entry / exit management system 1 further includes a storage unit 13 and a notification unit 14 inside or outside the hospital 2. The storage unit 13 is connected to the reading units 11A to 11D and the imaging units 12A to 12D, and stores the information acquired by them. The storage unit 13 may be a storage medium such as an HDD or an SD card capable of storing information, or may be a server on a network.

The notification unit 14 can communicate with the notification destination terminal 7, detects the patient 3 who has gone out from the hospital 2, and notifies the notification destination terminal 7 of the image of the patient 3 who has gone out.

The storage unit 13 and the notification unit 14 may be provided inside the hospital 2. Further, the storage unit 13 and the notification unit 14 may not be provided as separate units, but may be an integrated information terminal such as a personal computer or a building management terminal.

Hereinafter, in the room entry / exit management system 1, a configuration including a reading unit 11, an imaging unit 12, a storage unit 13, and a notification unit 14 will be referred to as an entry / exit management unit 10. The entry / exit management system 1 includes at least one target person terminal 4 and a notification destination terminal 7 for one entry / exit management unit 10.

Subsequently, the entry / exit management unit 10 of the first embodiment of the present application will be described in more detail with reference to FIG. FIG. 2 is a functional block diagram of the entry / exit management system 1. Although FIG. 2 shows a configuration not shown in FIG. 1, both show the same entry / exit management system 1.

First, the reading unit 11 will be described. The reading unit 11 reads the target person identification information unique to each target person terminal 4 stored internally in the target person terminal 4.

Here, the subject identification information will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a correspondence relationship between the patients 3A to 3D, the subject terminals 4A to 4D, and the subject identification information preset in the first embodiment. FIG. 3 shows, for example, that patient 3A possesses a subject terminal 4A that stores subject identification information "A".

Next, the information read by the reading unit 11 will be described. Here it will be described with reference to FIG. 4 to the position at time _{t n} of patients 3A ~ 3D. Figure 4 is an explanatory diagram showing the read area 5A ~ 5D for the patient 3 were present at time t _n. The time t _n is defined as the _{time t 1} , the time t ₂ , the time t ₃ ... At regular time intervals from _{the time t 1} when the entry / exit management unit 10 starts operation. For example, when the time t ₁ is 9:00 and the time interval is 1 minute, the time t ₂ is 9:01 and the time t ₃ is 9:02.

Figure 4, for example time _{t 1, the} patient 3A is read area 5A, cage patient 3D is read area 5D, patient 3B and the patient. 3C shows that was not in the hospital 2. Further, paying attention to the

patient

3A, 4 patients 3A the time _t 1 ~ _{t 2} the reading area 5A, the time _t 3 ~ _{t 4} the reading area 5B, the read area that 5A was at the time _t 5 ~ _{t 7} Shown.

When the position of the patient 3A ~ 3D at time _{t n} is shown in Figure 4, the target identification information reading unit 11A ~ 11D acquires at time _{t n} shown in FIG. FIG. 5 is an explanatory diagram showing the target person identification information acquired by the reading unit 11 at time t _n. _{The time t n} used in FIG. 5 is the same as the time t _{n shown in FIG.}

5, for example, at time t _1, the reading unit 11A obtains the target identification information "A", the reading unit 11D indicating acquisition target identification information "D". At time t _1, as shown in FIG. 4, the read area 5B and the reading area 5C, since the patient 3 were not present, not subject identification information and the reading unit 11B reader 11C acquired.

Next, the imaging unit 12 will be described. The imaging unit 12 acquires an image from the time when the reading unit 11 installed at least in the vicinity reads the target person identification information of the target person terminal 4 until it cannot be read. In particular, when the imaging unit 12 is used only for the purpose of confirming the image before and after going out, the imaging unit 12 does not have to perform imaging during the period when the reading unit 11 is not reading the target person identification information. By not operating the imaging unit 12 during the period when the reading unit 11 is not reading the target person identification information, the power for operating the imaging unit 12 can be reduced, and the operating cost of the entry / exit management system 1 can be reduced.

Here, an example of the information acquired by the imaging unit 12 is shown in FIG. 6, when the object identification information reading unit 11 acquires at time t _n is represented by FIG. 5 shows an image capturing unit 12A ~ 12D acquires at time t _n. _{The time t n} used in FIG. 6 is the same as _{the time t n} shown in FIGS. 4 and 5. Note that A1, A2, etc. in FIG. 6 indicate the video data itself acquired by the imaging unit 12.

For example, the imaging unit 12A at time _{t 1} in A1, the time _{t 2} at A2, at time _{t 3} acquires video data of A3. At time t _1, the reading unit 11A and the reading portion 11D as shown in FIG. 5 because reading the object identification information of the target terminal 4, the image pickup unit 12A and the imaging section 12D acquires the image in FIG. 6. At time t _1, since there is no subject identification information and the reading unit 11B reader 11C is obtained, it does not acquire an image even imaging unit 12B and the imaging unit 12C in FIG.

Next, the storage unit 13 will be described. The storage unit 13 includes a read information storage unit 131, a video storage unit 132, a target person information storage unit 133, and a notification destination information storage unit 134.

The reading information storage unit 131 stores the target person identification information acquired by the reading unit 11. In the first embodiment, the reading information storage unit 131 stores the target person identification information acquired by the reading units 11A to 11D in association with the _{time t n as shown in FIG.}

The image storage unit 132 stores the image from the imaging unit 12 for at least a predetermined time from when the nearby reading unit 11 reads the target person identification information until it cannot be read. This predetermined time may be 60 seconds, for example, as long as the image up to the moment when the patient 3 exits the door 6 can be stored. The video format stored by the video storage unit 132 may be a plurality of video formats acquired at a predetermined time or a moving image format. When the image storage unit 132 stores the image from the imaging unit 12 as a moving image, in the first embodiment, the reading information storage unit 131 is _{associated with the time t n} by the imaging units 12A to 12D as shown in FIG. Memorize the information of the video to be acquired.

The video storage unit 132 stores the video acquired from the imaging units 12A to 12D in the vicinity of the reading units A to 12D in association with the target person identification information stored in the reading information storage unit 131. In the first embodiment, the read information storage unit 131 stores _{the target person identification information in association with the time t n} , and the video storage unit 132 also stores the image _{in association with the time t n} , so that the read information is stored. and subject identification information stored in the section 131, it can be said that the images stored in the video storage unit 132 are stored in association with time t _n.

Further, the reading information storage unit 131 and the video storage unit 132 may be provided individually or integrally. Further, a reading information storage unit 131 and a video storage unit 132 may be provided in each of the reading areas 5A to 5D.

Here, FIG. 7 shows information stored in the storage unit 13 when the reading information storage unit 131 and the video storage unit 132 are provided integrally. FIG. 7 is an explanatory diagram showing an example of information stored by the read information storage unit 131 of the storage unit 13 and the video storage unit 132. As shown in FIG. 7, when the reading unit 11 acquires the target person identification information, the image from the imaging unit 12 is stored in association with the target person identification information. For example, the time t ₁ image A1 associated with the object identification information A in the video D1 associated with the object identification information D is stored. In the example shown in FIG. 4, the reading area 5 where the patient 3 is present, because it was never overlap in time t _n, also in FIG. 7, also overlap subject identification information associated with the certain video data Never. However, if a plurality of patients 3 are present in the same reading area 5 at the same time, the same video data may be stored for different subject identification information. The storage unit 13 stores not only the video associated with the target person identification information but also the time information.

The subject information storage unit 133 stores the information of the patient 3 in association with the subject identification information. The target person information storage unit 133 stores in advance the correspondence between the patients 3A to 3D, the target person terminals 4A to 4D, and the target person identification information as shown in FIG. 3, for example.

The notification destination information storage unit 134 stores information on the conditions of the notification destination terminal 7 in which the video notification unit 142 notifies the absence of the patient 3. FIG. 8 shows an example of the information stored in the notification destination information storage unit 134. FIG. 8 shows the information of the notification destination terminals 7A to 7D corresponding to the reading areas 5A to 5D in which the absent patient 3 was last detected. The notification destination information storage unit 134 may store the notification destination terminal identification information. The reading area 5 in which the absent patient 3 was last detected is the reading area 5 in which the reading unit 11 that last read the subject identification information of the patient 3 detected to be absent is installed. ..

In the example of FIG. 8, the notification condition regarding the notification destination terminal 7 is set so that the notification destination terminal 7 installed in the reading area 5 where the absent patient 3 is last detected is notified of the image of the absent patient 3. ing. For example, when the patient 3D detected as absent is finally detected in the reading area 5D, the notification destination terminal 7D is notified of the image of the patient 3D. By storing the information of the notification destination terminal 7 for notifying the image of the patient 3 detected as absent in the notification destination information storage unit 134 as shown in FIG. 8, the vicinity of the door 6 which is the entrance / exit where the patient 3 went out. A hospital person in the hospital 2 in the hospital can easily search for the patient 3 by checking the image of the absent patient 3. When the notification destination terminal 7 is a portable terminal, the information of the notification destination terminal 7 corresponding to the reading area 5 stored in the notification destination information storage unit 134 reflects the current position of the notification destination terminal 7. You may change it at any time. For example, the notification destination terminal 7 of the notification destination corresponding to each reading area 5 is the notification destination terminal 7 having the shortest distance to each reading area, or the notification destination terminal 7 within a predetermined distance. By setting the notification condition so that the notification destination terminal 7 close to the reading area 5 of the reading unit 11 that last detected the patient 3 becomes the notification destination in this way, the current position of the notification destination terminal 7 moves together with the hospital staff. However, it is possible to notify the hospital staff near the door 6, which is the entrance / exit where the patient 3 has gone out, of the image of the patient 3 who has been absent.

FIG. 9 shows an explanatory diagram showing another example of the conditions of the notification destination terminal 7 stored in the notification destination information storage unit 134. FIG. 9 shows the information of the notification destination terminals 7A to 7D for notifying the absence of the patients 3A to 3D. FIG. 9 shows, for example, that when the patient 3A is detected to be absent, it is the notification destination terminal 7A that notifies. By storing the information about the notification destination terminal 7 in the notification destination information storage unit 134 as shown in FIG. 9, for example, when it is detected that the patient 3A is absent, the reading area where the notification destination terminal 7A is installed is installed. The image of the patient 3A is notified to the notification destination terminal 7A regardless of the distance from the reading unit 11A of the notification destination terminal 7A or the notification destination terminal 7A. At this time, by having the notification destination terminal 7 possessed by the family of the patient 3, the family of the patient 3 outside the hospital 2 can know that the patient 3 has gone out of the hospital 2 and is absent, and the video can be displayed. Patient 3 can be easily searched after confirmation.

Next, the notification unit 14 will be described. The notification unit 14 includes an absentee detection unit 141 and a video notification unit 142.

The absentee detection unit 141 detects the target person identification information that has not been continuously stored in the reading information storage unit 131 for a predetermined time. This predetermined time is set to a time at which it is highly likely that the patient 3 has left the hospital 2. That is, the absentee detection unit 141 detects the subject identification information of the patient 3 who has gone out and was absent in the hospital 2.

The time at which patients 3A to 3D are likely to have gone out depends on how the reading unit 11 in the hospital 2 is installed. If each reading unit 11 is installed near the entrance / exit from the hospital 2 and the reading area of each reading unit 11 covers almost the entire inside of the hospital 2, this time may be set to zero. If this is not the case, the time is set so that it is considered that the patient 3 has left the reading area 5 and then has also left the hospital 2. Therefore, when the number of reading units 11 installed in the hospital 2 is small, the time is long, and when the number of reading units 11 is large, the time is short.

Here, the detection method by the absentee detection unit 141 will be described. The absentee detection unit 141 measures the elapsed time since the last reading of all the target person identification information stored in the target person information storage unit 133 by the reading unit 11. When the elapsed time from the last reading of the subject identification information of the subject terminal 4 reaches a predetermined time, it is detected that the subject terminal 4 is absent in the hospital 2. If it is detected that the subject terminal 4 is absent, it is known that the patient 3 is also absent.

The absentee detection unit 141 stores the target person identification information that has not been continuously stored in the reading information storage unit 131 for a predetermined time among the target person identification information of the target person terminal 4 registered in advance in the target person information storage unit 133. It may be detected, and if it is included, it may be detected as being in the room, and if it is not included, it may be detected as being absent.

FIG. 10 shows the time _{elapsed since the target person identification information at time t n} was last read by the reading unit 11. This elapsed time is counted as _{1 for every unit time t1.} The elapsed time is 0 for the target person identification information read by the reading unit 11 at time t _n. In the first embodiment, the absentee detection unit 141 counts the time when the subject identification information of the patient 3 is not read by all the reading units 11 when the patient 3 is considered to have gone out. It is detected that the patient 3 corresponding to the subject identification information is absent in the hospital 2. In Figure 10, at time t _7, subject identification information D from the became count 5, the patient 3D is detected in absentee detector 141 When it is absent in the hospital 2.

When the absentee detection unit 141 detects the subject identification information of the patient 3 who is absent, the video notification unit 142 is finally stored in the video of the absent patient 3 stored in the video storage unit 132. Notify the notification destination terminal 7 of the recorded video. At this time, the video notification unit 142 may simultaneously notify not only the video of the patient 3 who is absent, but also the information of the patient 3 or the time when it is considered that he / she has gone out.

FIG. 11 shows an example of an e-mail when the image notification unit 142 notifies the image of the patient 3 by e-mail. The notification destination terminal 7 that receives the mail of FIG. 11 is a mobile terminal capable of communicating. The video notification unit 142 sends an e-mail to the e-mail address of the notification destination terminal 7 stored in the notification destination information storage unit 134, stating that the patient 3 has gone out and a URL in which the last stored video of the patient 3 can be viewed. Will be sent. The video may be notified by attaching the video data itself to the e-mail instead of the URL in which the video can be viewed.

In FIG. 11, it is further stated in the body of the e-mail that the notification target person accesses the URL only when the patient 3 can be searched, "Please note that it is judged that it is possible to respond by accessing the above URL." At this time, by providing the video notification unit 142 with a means for detecting the presence / absence of access to the URL, if the URL is not accessed for a predetermined time after the notification, the notification target person cannot respond to the search for the patient 3. Can be detected. On the other hand, when the URL is accessed, it can be detected that the notification target person has responded to the search for the patient 3. If the video notification unit 142 is set in advance to send the same e-mail to the unnotified notification destination terminal 7 when the URL is not accessed for a predetermined time after the notification, the notified notification target person can perform the search response. If not, you can ask another person to be notified to respond to the search. By setting the video notification unit 142 in this way, even if the notification target person who received the notification cannot respond, the other notification target person can be automatically notified, so that he / she can easily and surely go out. The patient 3 can be searched.

FIG. 12 shows an explanatory diagram showing a display mode of the screen of the notification destination terminal 7 to which the image of the patient 3 is notified when the notification destination terminal 7 is installed in the hospital 2 as shown in FIG. At this time, the video notification unit 142 notifies the notification destination terminal 7 of the fact that the patient 3 has gone out and the last stored video of the patient 3. As shown in FIG. 12, the screen of the notification destination terminal 7 displays the image of the patient 3 before and after the time of going out and the fact that the patient has gone out, so that the hospital personnel and the like in the vicinity of the notification destination terminal 7 are displayed on the notification destination terminal 7. It is possible to search for the patient 3 by confirming the video.

Next, the operation of the entry / exit management system 1 of the first embodiment will be described. FIG. 13 is a flowchart showing the operation of the entry / exit management unit 10 of the entry / exit management system 1. The entry / exit management unit 10 starts the operation shown in FIG. 13 when the operation is started, and repeats the operation shown in FIG. 13 while managing the entry / exit of the patient 3 at the hospital 2.

First, the entry / exit management unit 10 determines in step S101 whether or not the reading unit 11 has read the target person identification information of the target person terminal 4. The entry / exit management unit 10 repeats step S101 until the reading unit 11 reads the target person identification information.

When the reading unit 11 reads the target person identification information of the target person terminal 4, the process proceeds to step S102, and the entry / exit management unit 10 acquires an image from the imaging unit 12 that captures the reading area of the reading unit 11 that has read the target person identification information. To do.

After step S102, the process proceeds to step S103, and the storage unit 13 stores the target person identification information read by the reading unit 11 in association with the image captured by the imaging unit 12.

After step S103, the process proceeds to step S104. In step S104, it is determined whether or not the absentee detection unit 141 has detected the target person identification information that has not been continuously stored in the reading information storage unit 131 for a predetermined time. If there is no subject identification information that has not been continuously stored for a predetermined time, the process returns to step S101, and steps S101 to S104 are repeated. When the absentee detection unit 141 detects the target person identification information that has not been continuously stored for a predetermined time, the process proceeds to step S105.

In step S105, the video notification unit 142 notifies the notification destination terminal 7 of the video of the patient 3 who has gone out detected by the absentee detection unit 141, which is the last video stored in the video storage unit 132.
