Description

  The present invention relates to entry / exit management technology, and more particularly to history management technology for reproducing past occupancy status based on entry / exit history information.

  Generally, in facilities and buildings, when security for outsiders is required for a specific management area, entry / exit of users in each room is strictly managed using an entrance / exit management system. For example, a reader and an electric lock are provided at the entrance and exit of a specific room, and on the basis of user identification information read by the reader from an ID card possessed by the user, the entrance / exit determination information stored in the storage unit in advance is referred to, The electric lock is controlled by determining whether or not the user can leave the room.

  In such an entrance / exit management system, when entering / leaving an ID card set in a reader installed in each room, history information relating to the entrance / exit is based on information set in the ID card and the operation terminal. A recording function is provided (see, for example, Patent Document 1). As this history information, for example, the date and time when the room was entered, the personal information of the person who entered and exited, and the operation status (room entry / exit) were recorded.

(Step 104) and return to step 100. The storage timing may be set with specific time information or may be set with a storage cycle.

[Resident behavior reproduction]
Next, the occupancy status reproduction operation of the history management apparatus 10 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating the occupancy status reproduction process of the history management apparatus according to the first embodiment.
When reproducing the occupancy status of each user at any past survey date and time based on the history information stored in the storage unit 14, the occupancy status reproduction process as shown in FIG. Is executed.

First, the operation input unit 12 acquires the survey date and time that is the target of the occupancy survey input by the operator (step 110).
Subsequently, the information acquisition unit 17 acquires, from the storage unit 14, the base occupancy status including the latest recorded occupancy status updated before the survey date and time among the recorded occupancy status saved in the storage unit 14. (Step 111), of the history information stored in the storage unit 14, the reproduction history information including the history information related to the entry / exit in the reproduction period from the date and time of the base occupancy status to the survey date and time is acquired from the storage unit 14 (Step 112).

Next, the occupancy status reproduction unit 18 initializes the occupancy status with the base occupancy status by setting the base occupancy status acquired by the information acquisition unit 17 as the initial occupancy status of each user ( Step 113).
Thereafter, the occupancy status reproduction unit 18 selects one piece of unprocessed history information from the reproduction history information in chronological order (step 114).

  Subsequently, the occupancy status reproduction unit 18 creates a new presence of the user on the basis of the reader ID of the reader where the room entry / exit operation has been performed and the destination determination table of the storage unit 14 recorded in the selection history information. The room location is identified (step 115), and the occupancy location and the entry date / time for the user are updated with the identified new occupancy location and the entry / exit date / time included in the selection history information in the re-current room status. (Step 116).

Thereafter, when there is still unprocessed history information among the reproduction history information (step 117: YES), the occupancy status reproduction unit 18 returns to step 114 to update the recurrent room status using the next history information. repeat.
On the other hand, when the processing of all the history information of the reproduction history information is completed (step 117: NO), the series of occupancy status reproduction processing is ended.

FIG. 7 is an explanatory diagram illustrating the occupancy status reproduction operation of the history management device according to the first embodiment. The overall operation of the occupancy status reproduction process described above is as shown in FIG.
In FIG. 7, date and time T is the current date and time, and date and time TX is the survey date and time when it is desired to reproduce the occupancy status.

In the storage unit 14, the recorded occupancy status 31 is stored for each fixed period ts. Among these recorded occupancy statuses 31, the latest recorded occupancy status updated before the survey date TX is the base occupancy status. It is acquired from the storage unit 14 as 31P.
Of the history information 32 in the storage unit 14, the history information in the reproduction period tp from the base date / time TP to the survey date / time TX, which is the date and time when the base occupancy status 31 </ b> P is updated, is stored as the reproduction history information 33. Obtained from.

  Thereafter, the re-current room state 35 is initialized by the base point room state 31P, and the initialized re-current room state 35P includes the history information included in the reproduction history information 33, the destination determination table of the storage unit 14, and Are updated sequentially. As a result, a re-current room situation 35A as shown in FIG. 4 indicating the room in which each user is present at the survey date TX is generated.

[Effect of the first embodiment]
As described above, in the present embodiment, the occupancy status update unit 16 stores the latest occupancy status in the storage unit 14 as the recorded occupancy status, and the occupancy status at the survey date and time that is the subject of the occupancy survey. Is reproduced by the information acquisition unit 17 from the latest recorded occupancy status updated before the survey date and the reproduction period from the base date and time when the base occupancy status was updated to the survey date The history information for reproduction consisting of the history information in the above is acquired from the storage unit 14, and the occupancy status reproduction unit 18 sets the base occupancy status to the initial occupancy status, and then is recorded in each reproduction history information. By sequentially updating the occupancy status based on the entrance / exit, the re-current room status indicating the occupancy status of each user at the survey date and time is generated.

  Thereby, when reproducing the occupancy status at the past survey date and time, the actual recorded occupancy status can be used as the base occupancy status. For this reason, when the reproduction information is generated based on the history information, it is not necessary to use the premise that no one is present in all the rooms at a certain base point as in the past. Accordingly, ambiguity is not included in the reproduced information such as the occupancy status, and extremely accurate reproduction information can be generated in a short processing time.

  In this embodiment, the case where the occupancy status of all users or all the rooms is reproduced in the occupancy survey is described as an example. However, only the occupancy status of the target room is reproduced in the occupancy survey. There are cases where it may be sufficient. In such a case, the re-current room situation may be generated based on only the history information related to the target room that has been input by the operator in the same manner as the survey date and time. Thereby, the amount of processing data in the occupancy survey can be reduced, and the processing time required for the occupancy survey can be shortened.

Specifically, in step 116 of FIG. 6 described above, at least when using the room location and the date and time of entry of the user who has entered or exited the room based on the information related to the room entry / exit recorded in the selection history information. Only when the person enters or leaves the target room, the room location and the date and time of entry may be updated.
For example, after step 115, it is determined whether the entry / exit source or entry destination recorded in the selection history information matches the target room. You should update the room entry date and time. In this case, as the entry / exit source, the occupancy location before update of the user to be updated acquired from the occupancy status may be used.

  Further, instead of determining whether or not the update is necessary in the processing loop of steps 114 to 117 in FIG. 6, when the information acquisition unit 17 acquires the reproduction history information from the storage unit 14, Only history information whose destination matches the target room may be selected and acquired in advance. Thereby, it is not necessary to determine whether or not the update is necessary in the processing loop.

The re-existing room status (first re-current room status) generated in step 1 is updated sequentially, so that the entrance status including the entrance status of users who entered the target room during the survey period (first survey period) 1) and a function of generating a selective entry situation relating only to the user who entered the target room from the generated entry situation.

  FIG. 9 is a configuration example of the room entry situation. Here, the occupancy room, the entry date and time, and the registration determination flag are registered as a set for each user. The registration determination flag is a flag indicating whether or not the target room is entered during the survey period. A user whose registration determination flag is ON indicates that the user has entered the target room during the survey period, and the target room is recorded as an occupancy room. The date and time of entry is recorded. On the other hand, the user whose registration determination flag is OFF indicates that the user has not entered the target room during the survey period, and the room that was present at the start date and time of the survey period is recorded as the room present. The date and time when the user entered the room is recorded as the entry date and time.

  In general, in the entrance situation actually used in the entrance / exit management system, at least information such as a registration determination flag indicating whether or not to enter the target room during the survey period should be recorded for each user. . In the present embodiment, in addition to this, an example will be described in which the first entry date and time when the user first entered the target room during the survey period is recorded. The contents of the room entry status are not limited to the registration determination flag or the first entry date / time, but include information such as the entry date / time when the user entered the target room again after the first entry date / time and the exit date / time when the user left the target room. May be.

  In addition, the information acquisition unit 17 is the base occupancy status updated before the start date / time of the input survey period (first survey period) in the recorded occupancy status, and the record recorded most recently from the start date / time From the function of acquiring the occupancy status consisting of the occupancy status from the storage unit 14 and the history information in the reproduction period (first reproduction period) from the date and time of the occupancy status to the start date and time of the survey period in the history information The history information for reproduction (first reproduction history information) to be obtained from the storage unit 14 and the history information in the investigation period (first investigation period) from the start date to the end date of the investigation period in the history information And a function of acquiring the history information for aggregation (first history information for aggregation) from the storage unit 14.

Further, the occupancy status reproduction unit 18 sets the base occupancy status acquired by the information acquisition unit 17 as an initial occupancy status, thereby initializing the occupancy status with the base occupancy status, and for each reproduction. Each use at the start date and time of the survey period by sequentially updating the occupancy status based on the information related to the entry / exit recorded in the history information (first reproduction history information) and the destination determination table of the storage unit 14 And a function of generating a re-current room state (first re-current room state) indicating a person's occupancy state.
In the history management apparatus 10 according to the present embodiment, configurations other than these are the same as those in the first embodiment, and detailed description thereof is omitted here.

FIG. 10 is a flowchart illustrating a room entry status generation process of the history management apparatus according to the second embodiment. FIG. 11 is a flowchart illustrating room entry status generation processing (continued) of the history management apparatus according to the second embodiment.
As shown in FIG. 10 and FIG. 11 in the history management apparatus 10 when reproducing the room entry status of the user who entered the target room in the past arbitrary survey period based on the history information stored in the storage unit 14. The room entry status generation process is executed.

First, the operation input unit 12 acquires a survey period and a target room to be surveyed, which are input by the operator (step 200).
Subsequently, the information acquisition unit 17 obtains, from the storage unit 14, the base occupancy status including the latest recorded occupancy status updated before the survey period start date / time from the recorded occupancy status stored in the storage unit 14. Retrieval history information consisting of history information about entry / exit in the reproduction period from the date and time of the base occupancy status to the start date and time of the survey period, among the history information acquired (step 201) and stored in the storage unit 14, The history information for aggregation consisting of the history information related to the entrance / exit in the survey period from the start date to the end date of the survey period is acquired from the storage unit 14 (step 202).

Next, the occupancy status reproduction unit 18 initializes the occupancy status with the base occupancy status by setting the base occupancy status acquired by the information acquisition unit 17 as the initial occupancy status of each user. (Step 203), the registration determination flag of each user is initialized to OFF (Step 204).
Thereafter, the occupancy status reproduction unit 18 selects one unprocessed history information from the reproduction history information in chronological order (step 205).

  Subsequently, the occupancy status reproduction unit 18 creates a new presence of the user on the basis of the reader ID of the reader where the room entry / exit operation has been performed and the destination determination table of the storage unit 14 recorded in the selection history information. The room location is identified (step 206), and the occupancy location and entry date / time regarding the user recorded in the selection history information among the re-current room status are included in the identified new occupancy location and selection history information. Update with the entry / exit date (step 207),

Thereafter, when there is still unprocessed history information among the reproduction history information (step 208: YES), the occupancy status reproduction unit 18 returns to step 204 to update the re-current room status with the next history information. repeat.

The registration determination flag for each user in the room is set to ON (step 209).

  Subsequently, the room entry status generation unit 19 selects one piece of unprocessed history information from the total history information in chronological order (step 210), and the entry / exit operation recorded in the selection history information is performed. Based on the reader ID of the reader and the destination determination table in the storage unit 14, the user's new room location is specified (step 211), and it is confirmed whether the new room location matches the target room (step 211). Step 212).

Here, when the new occupancy location matches the target room (step 212: YES), the occupancy status generation unit 19 confirms the registration determination flag of the user and determines whether or not it has been registered in the occupancy status. (Step 213) When the registration determination flag is OFF and not registered (Step 213: YES), the user's occupancy location and entry date / time are updated in the room entry status (Step 214), and the user's After setting the registration determination flag to ON (step 215), the process proceeds to step 216 described later.
If the new occupancy location does not match the target room (step 212: NO), or if the user's registration determination flag is ON and registered in the room entry status (step 213: NO), the room entry status is updated. Instead, the process proceeds to step 216 described later.

Thereafter, when there is still unprocessed history information among the totaling history information (step 216: YES), the room entrance status generation unit 19 returns to step 210 and repeats the process of updating the room entrance status with the next history information.
On the other hand, when the processing of all the history information of the total history information is completed (step 216: NO), the room entrance status generation unit 19 stores the room entrance status obtained in steps 210 to 216 in the storage unit 14, From this room entry situation, a selection room entry situation relating to a user whose registration determination flag is ON is generated and stored in the storage unit 14 (step 217), and a series of room entry situation generation processing is terminated.

FIG. 12 is an explanatory diagram illustrating a room entrance state generation operation of the history management apparatus according to the second embodiment. The overall operation of the room entry status generation process described above is as shown in FIG.
In FIG. 12, date and time T is the current date and time, date and time TX is the start date and time of the survey period tc for which a room entry situation is to be generated, and date and time TY is the end date and time of the survey period tc.

  In the storage unit 14, the recorded occupancy status 31 is stored for each fixed period ts, and the latest recorded occupancy status updated before the survey start date and time TX among the recorded occupancy statuses 31 is the base occupancy status. It is acquired from the storage unit 14 as the situation 31P.

  Of the history information 32 in the storage unit 14, the history information in the reproduction period tp from the base date / time TP to the survey start date / time TX, which is the date and time when the base occupancy status 31 </ b> P is updated, is stored as the reproduction history information 33. 14, the history information in the survey period tc from the survey start date and time TX to the survey end date and time TY is acquired as totaling history information 34.

  Thereafter, the re-current room state 35 is initialized by the base point room state 31P, and the initialized re-current room state 35P includes the history information included in the reproduction history information 33, the destination determination table of the storage unit 14, and Are updated sequentially. As a result, the re-current room situation 35A as shown in FIG. 4 showing the room where each user is present at the survey start date and time TX is reproduced.

Next, the re-current room status 35A is sequentially updated by history information indicating entry into the target room among the history information included in the total history information 34 and the destination determination table of the storage unit 14. As a result, as shown in FIG. 9, an entrance situation 36A including the entrance situation of the user who entered the target room in the survey period tc is generated.
At this time, the obtained entrance situation 36A includes the entrance situation before the survey period tc of the user who has not entered the target room. Accordingly, the selected entry situation 36S may be generated by selecting the entry situation relating to only the user who entered the target room from among the entry situations 36A with the registration determination flag being ON.

[Effect of the second embodiment]
As described above, this embodiment reproduces the same as the above-described first embodiment, and the entrance status generation unit 19 displays the entrance status based on the re-present room status at the start date and time of any past survey period.

Thus, the room entry status is updated by the room entrance status generation unit 19 to generate the room entrance status of the user who entered the target room during the survey period.

  Thereby, when the room entrance situation in the past survey period is generated, the actual recorded room situation can be used as the base room presence situation. For this reason, it is not necessary to use the premise that no one is present in all the rooms at a certain base point as in the prior art. Therefore, the generated entry situation does not include ambiguity, and it is possible to generate an extremely accurate entry situation in a short processing time.

  Moreover, in this embodiment, when reproducing the occupancy status, the case where the occupancy status of all users or all the rooms is reproduced is described as an example. Only the occupancy status relating to the target room is used in the subsequent process of generating the entrance status. Therefore, the re-current room situation may be generated based only on the history information about the target room. Thereby, the amount of processing data in the occupancy survey can be reduced, and the processing time required for the occupancy survey can be shortened. As a specific example of generating the occupancy status of only the target room, the method described in the first embodiment may be used.

  Moreover, in this embodiment, all history information in the survey period is acquired as history information for the survey period as history information for generating the room entry status. I need only. Therefore, when the information acquisition unit 17 acquires the history information for aggregation from the storage unit 14, only the history information related to the target room is selected and acquired from the history information in the survey period based on the destination determination table. It may be. Accordingly, it is possible to reduce the amount of processing data in the generation of the room entry status, and it is possible to shorten the time required for the process for generating the room entrance status.

Subsequently, the information acquisition unit 17 has the latest recorded occupancy status updated before the start date and time of the first survey period located at the beginning of each survey period among the recorded occupancy statuses stored in the storage unit 14. Is acquired from the storage unit 14 (step 301), and the initial occupancy status is initialized as the occupancy status of each user by setting the base occupancy status as the initial occupancy status of each user. (Step 302).

  Next, the room entrance status generation unit 19 initializes the registration determination flag assigned for each user to OFF (step 303). The registration determination flag is flag information for determining whether or not the user is already registered in the room entry status, and is stored in the storage unit 14.

Thereafter, the room entry status generation unit 19 selects one unprocessed survey period in time series order from among the plurality of survey periods (step 310).
The information acquisition unit 17 includes, for history information stored in the storage unit 14, reproduction history information including history information in a reproduction period corresponding to a selection investigation period, and investigation from a start date to an end date of the selection investigation period. The history information for aggregation consisting of the history information related to entering and leaving the room during the period is acquired from the storage unit 14 (step 311).

  When the selected survey period is the first survey period (first survey period), the reproduction period (first reproduction period) is from the date / time of the base room presence status to the start date / time of the survey period. If the selected survey period is the second or later survey period (second survey period), the period from the end date / time of the survey period located immediately before the selected survey period to the start date / time of the selected survey period is reproduced. This is a period (second reproduction period).

  Next, the occupancy status reproduction unit 18 selects one piece of unprocessed history information from the reproduction history information in chronological order (step 312), and the entry / exit operation recorded in the selection history information is performed. Based on the reader ID of the reader that has been performed and the destination determination table in the storage unit 14, the user's new location is specified (step 313), and the user's registration determination flag is referred to to determine the usage. It is determined whether the person has been registered in the room entry status (step 314).

Here, when the registration determination flag is OFF and the user is not registered in the room entry status (step 314: YES), the occupancy status reproduction unit 18 determines the occupancy location relating to the user among the recurrent room status. The room entry date / time is updated with the specified new room location and the room entry / exit date / time included in the selection history information (step 315).
On the other hand, if the registration determination flag is ON and the user is registered in the room entry status (step 314: NO), the process proceeds to step 316 described later without registering in the room entrance status.

Thereafter, when there is still unprocessed history information among the reproduction history information (step 316: YES), the occupancy status reproduction unit 18 returns to step 312 to update the recurrent room status with the next history information. repeat.
On the other hand, when the processing of all the history information of the reproduction history information has been completed (step 316: NO), the room entrance status generation unit 19 uses all of the obtained room entrance statuses where the occupancy room matches the target room. The registration determination flag of the user is set to registered (step 317).

  Subsequently, the room entry status generation unit 19 selects one piece of unprocessed history information from the total history information in chronological order (step 320), and the entry / exit operation recorded in the selection history information is performed. Based on the reader ID of the reader and the destination determination table of the storage unit 14, the user's new room location is specified (step 321), and it is confirmed whether the new room location matches the target room (step 321). Step 322).

  Here, when the new occupancy location matches the target room (step 322: YES), the entrance status generation unit 19 refers to the registration determination flag of the user and the user has already been registered in the entrance status. (Step 323), and if the registration determination flag is OFF and not registered (step 323: YES), the room location and the date and time of entry of the user are updated in the room entry status (step 324). Then, after setting the registration determination flag of the user to ON (step 325), the process proceeds to step 326 described later.

If the new room location does not match the target room (step 322: NO), or if the user's registration determination flag is ON and the room is already registered (step 323: NO), the room entry status is updated. Instead, the process proceeds to step 326 described later.
Thereafter, when there is still unprocessed history information among the totaling history information (step 326: YES), the room entrance status generation unit 19 returns to step 320 and repeats the process of updating the room entrance status with the next history information.

  On the other hand, when the processing of all the history information of the history information for aggregation is completed (step 326: NO), the room entrance status generation unit 19 examines the room entrance status obtained by the processing of steps 320 to 326 for each of the previous surveys. When the room entry status in the period is stored in the storage unit 14 and there is still an unprocessed survey period (step 330: YES), the process returns to step 310 in FIG. 13 to repeat the process of generating the room status in the next survey period.

  Further, when the processing for all the survey periods is completed (step 330: NO), the storage unit 14 generates a selected entry situation regarding the user whose registration determination flag is ON from among the entry conditions stored in the storage unit 14. 14 (step 331), and a series of room entrance status generation processing is terminated.

Are updated sequentially. As a result, as shown in FIG. 4, the first recurrent room situation 35A indicating the room where each user is present at the survey start date and time TXA is reproduced.

  Next, the re-current room status 35A is sequentially updated by history information indicating entry into the target room among the history information included in the total history information 34A and the destination determination table in the storage unit 14. As a result, as shown in FIG. 9, a first entry situation 36A including the entry situation of the user who entered the target room in the survey period tcA is generated.

Subsequently, the process for generating the room entry status in the second survey period tcB is started.
First, of the history information 32 in the storage unit 14, history information in the second reproduction period tpB from the survey end date TYA to the survey start date TXB in the immediately previous survey period tcA is stored as second reproduction history information 33B. The history information in the survey period tcB from the survey start date and time TXB to the survey end date and time TYB is acquired as the second tabulation history information 34B.

  Thereafter, the first room entry status 36A is sequentially updated by the history information included in the reproduction history information 33B and the destination determination table of the storage unit 14. As a result, the second re-current room situation 35B as shown in FIG. 4 showing the room where each user is present at the survey start date and time TXB is reproduced.

Next, the second recurrent room situation 35B is sequentially updated by the history information indicating entry into the target room and the destination determination table in the storage unit 14 among the pieces of history information included in the history information 34B for aggregation. . As a result, as shown in FIG. 9, a second room entry state 36 </ b> B including the room entry state of the user who entered the target room during the research period tcA and the research period tcB is generated.
At this time, the obtained entrance situation 36B includes the entrance situation before the survey period tcB of the users who have not entered the target room. Therefore, the selected entry situation 36S may be generated by selecting the entry situation relating to only the user who entered the target room from among the entry situations 36B when the registration determination flag is ON.

[Effect of the third embodiment]
As described above, in the present embodiment, the room entrance state generation process described in the second embodiment is repeatedly performed for each survey period, and the second and subsequent survey periods (second survey periods) are executed. Since the entry status obtained from the entry status generation process in the immediately preceding survey period is used as the initial value of the new reproduction history information, multiple discontinuous survey periods are specified However, it is possible to easily generate the room entry status of the person who entered the target room during the survey period.

  Further, in the present embodiment, as in the second embodiment, when reproducing the occupancy status, the case of reproducing the occupancy status of all users or all rooms has been described as an example. In this room status, only the room status relating to the target room is used in the subsequent process of generating the room status. Therefore, the re-current room situation may be generated based only on the history information about the target room. Thereby, the amount of processing data in the occupancy survey can be reduced, and the processing time required for the occupancy survey can be shortened. As a specific example of generating the occupancy status of only the target room, the method described in the first embodiment may be used.

  Moreover, in this embodiment, as in the second embodiment, all history information in the survey period is acquired as history information for tabulation as history information for generating the room entry status. Only the history related to the target room among the history information for aggregation is sufficient. Therefore, when the information acquisition unit 17 acquires the history information for aggregation from the storage unit 14, only the history information related to the target room is selected and acquired from the history information in the survey period based on the destination determination table. It may be. Accordingly, it is possible to reduce the amount of processing data in the generation of the room entry status, and it is possible to shorten the time required for the process for generating the room entrance status.
