The determination process corresponds to the exit of the user 2 from the predetermined area A1 being the Nth from the last specific exit from the predetermined area A1 based on the specific article information acquired by the article information acquisition unit 50. It is a process of determining whether or not.

In the present embodiment, the determination unit 31 determines whether or not the exit of the user 2 from the predetermined area A1 is a specific exit based on the specific article information and the user information. Specifically, in the present embodiment, the determination unit 31 acquires the specific article information by the communication unit 5 (article information acquisition unit 50) and the user information by the communication unit 5 (user information acquisition unit 51). The time determination process for determining whether or not the difference time from the time when the item is acquired is within a predetermined time is executed. Then, the determination unit 31 determines that the exit of the user 2 from the predetermined area A1 is the specific exit if the difference time is within the predetermined time. In other words, in the determination unit 31, the acquisition of the specific article information by the article information acquisition unit 50 and the acquisition of the user information by the user information acquisition unit 51 are performed within a predetermined time (for example, 1 second). In this case, it is determined that the exit of the user 2 from the predetermined area A1 is a specific exit.

For example, as shown in FIG. 2, it is assumed that the user 2 is moving from the predetermined area A1 to the area A2 in the state of possessing the specific article 1. In this case, the article information acquisition unit 50 and the user information acquisition unit 51 acquire the specific article information corresponding to the specific article 1 and the user information corresponding to the user 2, respectively. Since the user 2 is moving while possessing the specific article 1, the acquisition of the specific article information and the acquisition of the user information are performed within a predetermined time. Therefore, the determination unit 31 determines that the user 2 will specifically leave the predetermined area A1.

On the other hand, as shown in FIG. 3, it is assumed that the user 2 is moving from the predetermined area A1 to the area A2 without possessing the specific article 1. In this case, the user information acquisition unit 51 acquires the user information corresponding to the user 2, but the article information acquisition unit 50 does not acquire the specific article information. Therefore, the determination unit 31 determines that the user 2 temporarily leaves the predetermined area A1.

When it is determined that the exit from the predetermined area A1 of the user 2 is a specific exit, the determination unit 31 is a variable representing, for example, the number of current users 2 in the predetermined area A1 stored in a memory or the like. To decrement. Then, the determination unit 31 determines whether or not the variable after decrementing (that is, the number of users 2 in the predetermined area A1) has reached the threshold value (here, “N-1”). When the variable after decrement reaches the threshold value, the determination unit 31 determines that the specific exit of the user 2 corresponds to the Nth specific exit from the predetermined area A1 from the end.

The update unit 32 updates the exit information regarding the exit for each user 2 based on the specific article information. The "exit information" referred to in the present disclosure includes information indicating whether or not the user 2 has specifically exited from the predetermined area A1. Specifically, when the determination unit 31 determines that the user 2's exit from the predetermined area A1 is the specific exit based on the specific article information, the update unit 32 is stored in the storage unit 4. Update the exit information of the user 2 who is using. For example, when the user 2 specifically exits from the predetermined area A1, the update unit 32 changes the exit information of the user 2 from "inside the predetermined area A1" to "outside the predetermined area A1: specific exit". Update. Further, for example, when the user 2 temporarily exits from the predetermined area A1, the updating unit 32 changes the exit information of the user 2 from "inside the predetermined area A1" to "outside the predetermined area A1: Update to "Temporary Exit".

In the time determination process executed by the determination unit 31, the notification unit 33 notifies the abnormality when the difference time exceeds a predetermined time.

When the condition determination unit 34 determines that the predetermined conditions are satisfied, the display control unit 35 causes the display unit 7 to display a message, an image, or the like indicating that all the predetermined conditions are satisfied. In this case, the display control unit 35 does not have to display anything on the display unit 7.

On the other hand, when the condition determination unit 34 determines that the predetermined condition is not satisfied, the display control unit 35 causes the display unit 7 to display a message or an image indicating that the predetermined condition is not satisfied. As an example, when the detection result of the first sensor 61 is abnormal, the display control unit 35 causes the display unit 7 to display a message or an image prompting the user to close the window of the predetermined area A1. When the detection result of the second sensor 62 is abnormal, the display control unit 35 causes the display unit 7 to display a message or an image urging the lighting fixture in the predetermined area A1 to be turned off. When the detection result of the third sensor 63 is abnormal, the display control unit 35 causes the display unit 7 to display a message or an image prompting the user to switch the molded case circuit breaker in the predetermined area A1 to the off state. .. When the detection result of the fourth sensor 64 is abnormal, the display control unit 35 causes the display unit 7 to display a message, an image, or the like urging the equipment in the predetermined area A1 to be placed at the predetermined position.

As an example, the storage unit 4 is composed of at least one of a non-temporary recording medium such as a hard disk and a non-temporary recording medium such as a rewritable non-volatile semiconductor memory. The storage unit 4 stores the exit information for each user 2. The exit information is information on whether or not the user 2 exists in the predetermined area A1, and if the user 2 exists outside the predetermined area A1, information on whether the user 2 is a temporary exit or a specific exit.

That is, the determination unit 31 clocks a predetermined time from the time when the specific article information is acquired, and monitors whether or not the user information is acquired within the predetermined time (S2).

When the user information is acquired within the predetermined time (S2: Yes), the determination unit 31 determines that the user 2 has left the predetermined area A1 and that the exit is a specific exit (S3). ). In this case, the update unit 32 updates the exit information of the user 2 from "inside the predetermined area A1" to "outside the predetermined area A1: specific exit" (S4). On the other hand, when the user information cannot be acquired within a predetermined time (S2: No), the notification unit 33 notifies the abnormality (S5).

On the other hand, when the communication unit 5 acquires the user information (S6: Yes) without acquiring the specific article information (S1: No), the determination unit 31 causes the user 2 to leave the predetermined area A1. Moreover, it is determined that the exit is a temporary exit (S7). In this case, the update unit 32 updates the exit information of the user 2 from "inside the predetermined area A1" to "outside the predetermined area A1: temporary exit" (S8).

When it is determined that the exit from the predetermined area A1 of the user 2 is a specific exit, the determination unit 31 corresponds to the specific exit of the user 2 being the Nth specific exit from the predetermined area A1 from the end. It is determined whether or not to do so (S9). If applicable (S9: Yes), the condition determination unit 34 determines whether or not a predetermined condition is satisfied (S10). When the predetermined condition is not satisfied (S10: No), the display control unit 35 causes the user 2 to satisfy the predetermined condition by displaying a message or the like indicating that the predetermined condition is not satisfied on the display unit 7. Notify that it is not satisfied (S11).

As described above, in the present embodiment, the determination unit 31 can determine what kind of exit the user 2 from the predetermined area A1 corresponds to. Therefore, the present embodiment has an advantage that it is easier to grasp the exit mode of the user 2 as compared with a system that manages the entrance and exit of the user 2 to the predetermined area A1 by using an IC card, for example. ..

That is, in the exit management system using an IC card, it is possible to manage the entrance and exit of the user 2 to the predetermined area A1, but the exit from the predetermined area A1 of the user 2 is a temporary exit. It is difficult to manage whether it is a specific exit or a specific exit. On the other hand, in the present embodiment, is the exit from the predetermined area A1 of the user 2 a temporary exit by using the specific article information of the specific article 1 involved in the specific exit of the user 2? , It is possible to manage whether it is a specific exit. In the present embodiment, the bag to be carried when the user 2 leaves the office for a relatively long period of time, such as when leaving work or on a business trip, is defined as the specific article 1. Therefore, in the present embodiment, the determination unit 31 determines the movement of the specific article 1 (bag) based on the specific article information, so that the user 2 possessing the bag specifically leaves the predetermined area A1. It is possible to determine that.

Further, in the present embodiment, the determination unit 31 determines whether or not the specific exit from the predetermined area A1 of the user 2 corresponds to the Nth specific exit from the predetermined area A1 from the end. There is. Therefore, in the present embodiment, for example, when the user 2 is the last person (that is, “N = 1”) who specifically leaves the predetermined area A1, some measures are taken against the user 2. Is possible. As an example, the measure does not satisfy the conditions (predetermined conditions) necessary for prompting the user 2 to inspect when closing the predetermined area A1 or closing the predetermined area A1. It is to notify that.

In addition, in the present embodiment, for example, when the user 2 is the Nth from the last (“N” is a natural number of 3 or more) that specifically leaves the predetermined area A1, a plurality of uses remaining in the predetermined area A1. It is possible to urge the person 2 to inspect when closing the predetermined area A1. This aspect is useful, for example, when a plurality of people are required for inspection.

(4) Modifications The above embodiment is only one of the various embodiments of the present disclosure. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Further, the same function as the exit management system 100 may be realized by an exit management method, a (computer) program, a non-temporary recording medium on which the program is recorded, or the like.

The exit management method according to one aspect includes an acquisition step and a determination step. The acquisition step is a step of acquiring specific article information. The specific article information is information about the specific article 1 associated with the user 2 in the predetermined area A1 which is read by performing wireless communication with the reading unit 102 using radio waves as a medium. The determination step is a step of determining whether or not the exit of the user 2 from the predetermined area A1 corresponds to the Nth specific exit from the predetermined area A1 based on the acquired specific article information. Is.

The program according to one aspect causes one or more processors to execute the above-mentioned exit management method.

Hereinafter, modifications of the above-described embodiment will be listed. The modifications described below can be applied in combination as appropriate.

(4.1) First Modified Example In the exit management system 100A of the first modified example, as shown in FIGS. 5 and 6, the specific article 1 is not a bag but a work clothes, according to the above-described embodiment. It is different from the exit management system 100. Then, in this modified example, the criteria for determining whether or not the exit from the predetermined area A1 of the user 2 is a specific exit is different from the exit management system 100 of the above-described embodiment. Specifically, in the determination unit 31, the user information acquisition unit 51 acquires the user information, the article information acquisition unit 50 acquires the specific article information, and the user information acquisition unit 51 acquires the user. If the acquisition of information is not performed within a predetermined time, it is determined that the exit of the user 2 from the predetermined area A1 is a specific exit. Further, the determination unit 31 determines the predetermined area A1 when the article information acquisition unit 50 acquires the specific article information and the user information acquisition unit 51 acquires the user information within a predetermined time. It is determined that the exit of the user 2 from is a temporary exit.

For example, as shown in FIG. 5, it is assumed that the user 2 is moving from the predetermined area A1 to the area A2 without possessing the specific article 1. In this case, the user information acquisition unit 51 acquires the user information corresponding to the user 2, but the article information acquisition unit 50 does not acquire the specific article information. Therefore, the determination unit 31 determines that the user 2 will specifically leave the predetermined area A1.

On the other hand, as shown in FIG. 6, it is assumed that the user 2 is moving from the predetermined area A1 to the area A2 in a state of possessing the specific article 1 (that is, wearing work clothes). In this case, the article information acquisition unit 50 and the user information acquisition unit 51 acquire the specific article information corresponding to the specific article 1 and the user information corresponding to the user 2, respectively. Since the user 2 is moving while possessing the specific article 1, the acquisition of the specific article information and the acquisition of the user information are performed within a predetermined time. Therefore, the determination unit 31 determines that the user 2 temporarily leaves the predetermined area A1.

That is, in the present modification, the specific article 1 is work clothes, and is an article that is prohibited from being taken out from the predetermined area A1 at the time of the specific exit. Therefore, unlike the above-described embodiment, the determination unit 31 is temporarily exited when the specific article 1 is left behind in the predetermined area A1, and temporarily when the specific article 1 is taken out of the predetermined area A1. It is judged that it is a typical exit. In this way, the specific article 1 includes an article taken out from the predetermined area A1 at the time of specific exit, such as a bag owned by the user 2, and also includes work clothes worn by the user 2 at the time of specific exit. It may include articles left behind in a predetermined area A1.

(4.2) Second Modified Example In the exit management system 100B of the second modified example, as shown in FIG. 7, the reading system 10 is installed not only in the predetermined area A1 but also in the area A2 sandwiching the gate G1. Has been done. That is, this modification is different from the above-described embodiment in that the user information acquisition unit 51 can acquire user information from the inside and the outside of the predetermined area A1. As described above, in this modification, the environment to which the exit management system 100B is applied is different from that of the above-described embodiment, but the configuration of the exit management system 100B is the same as that of the exit management system 100 of the above-described embodiment. .. However, in this modification, the determination unit 31 determines the direction of movement of the specific article 1 and the user 2 based on the reading results of the plurality of reading units 102, and the exit management system of the above-described embodiment. Different from 100.

That is, the determination unit 31 moves the specific article 1 and the user 2 based on the order in which the peak of the reading frequency (or the intensity of the received radio wave) of the article tag 11 or the user tag 21 is read by the reading unit 102. Determine the orientation of. For example, when the peak occurs in the order of the predetermined area A1 and the area A2, the specific article 1 and the user 2 move from the predetermined area A1 to the area A2, that is, the user 2 leaves the predetermined area A1. Is determined. Further, for example, when the peak occurs in the order of area A2 and predetermined area A1, the specific article 1 and the user 2 move from the area A2 to the predetermined area A1, that is, the user 2 enters the predetermined area A1. Judge to do.

In this modification, at least the direction of movement of the user 2 can be determined, so that it is possible to grasp whether the user 2 enters the predetermined area A1 or exits from the predetermined area A1. There is an advantage.

(4.3) Third Modified Example In the third modified example, the determination unit 31 determines whether or not the exit from the predetermined area A1 of the user 2 is a specific exit as described below. , Different from the exit management system 100 of the above-described embodiment. That is, in this modification, the determination unit 31 starts from the predetermined area A1 of the user 2 based on the degree of similarity between the time-dependent change in the reading state of the specific article information and the time-dependent change in the reading state of the user information. It is determined whether or not the exit of is a specific exit. The similarity is based on, for example, at least one of the number of readings, the time interval, the frequency, the intensity of the received radio wave, and the phase of the received radio wave by the reading unit 102 of the article tag 11 and the user tag 21. ing.

The "number of readings" referred to in the present disclosure means the number of times that the reading unit 102 has read the specific article information (or user information) within a certain period, and more specifically, the reading unit 102 has read the specific article information (or user information). It is the number of times that the specific article information (or user information) is successfully read. The "reading time interval" as used in the present disclosure means a time interval in which the reading unit 102 reads the specific article information (or user information) within a certain period of time. More specifically, when the reading unit 102 succeeds in reading the specific article information (or user information) twice, the second specific article from the time of reading the first specific article information (or user information). It is the time until the time when the information (or user information) is read. The "reading frequency" referred to in the present disclosure means the frequency with which the reading unit 102 reads the specific article information (or user information) within a certain period, and more specifically, the reading unit 102 reads. This is the frequency with which the specific article information (or user information) was successfully read. The “received radio wave strength” referred to in the present disclosure is the strength of the radio wave transmitted from the article tag 11 or the user tag 21 received by the antenna 101 of the reading system 10, and as an example, RSSI (Received Signal Strength Indication). Expressed as a value. The "phase of the received radio wave" referred to in the present disclosure is the phase of the radio wave transmitted from the article tag 11 or the user tag 21 received by the antenna 101 of the reading system 10.

As an example, it is assumed that the similarity is a correlation coefficient calculated based on the frequency of reading by the reading unit 102 of the article tag 11 and the frequency of reading by the reading unit 102 of the user tag 21. To do. In this case, if the calculated correlation coefficient is equal to or greater than the threshold value, the determination unit 31 is moving with the specific article 1 in possession, that is, the user 2 is specifically leaving the predetermined area A1. Judge to do. On the other hand, the determination unit 31 determines that the user 2 does not specifically leave the predetermined area A1 if the calculated correlation coefficient is less than the threshold value. The latter situation can occur, for example, when the specific article 1 is present around the reading unit 102, but the user 2 is moving without possessing the specific article 1.

In this modification, since it is possible to determine whether or not the user 2 is in possession of the specific article 1 and is moving, the accuracy of determining the specific exit of the user 2 from the predetermined area A1 is likely to be improved. , Has the advantage.
