[0004]
In FIG. 6, for example, when entering the A conference room 1-6 from the laboratory 1-3, an ID card for personal identification is set in the card reader 2-7 and an input operation is performed. Then, the unique data (card No.) written on the personal identification ID card is read and sent to a center device (not shown). The center device specifies the personal name of the card user based on the transmitted unique data, and opens the door to the A conference room 1-6. Further, the center device records the entry / exit status (entry), the reader location (entry location), and the entry time as entry information in the database in combination with the card user's personal name (entry name).
[0005]
When exiting from the A conference room 1-6, the door can be freely opened from the inside, so enter the laboratory 1-3, set an ID card for personal identification in the card reader 2-7, and exit. Perform the operation. As a result, the center device records the entry / exit status (exit), the leader location (exit location), and the exit time as exit information in the database in pairs with the card user's personal name (exit name).
[0006]
FIG. 7 is a diagram showing the storage status of entry information and exit information in the database of the center device. Entry information and exit information are accumulated in chronological order. In this example, “time”, “entrance / exit status”, “leader location”, and “name” are recorded as one set in one accumulation record. The entry information and exit information recorded in this database can be displayed on a display or printed by a printer as needed.
[0007]
FIG. 8 is a display example of entry information and exit information. The center device displays the entry information and the exit information recorded in the database in the order of newest time or oldest time. The same entry information and exit information are also printed by the printer.
[0008]
[Problems to be solved by the invention]
However, in such a conventional entry / exit management system, when a certain individual wants to know in which room the user entered the room, and from which room the user left the room, the displayed or printed entry information and exit information are written in one line. One line must be tracked, and the applicable line must be re-created in pairs with entry and exit, making it difficult to use and time-consuming to search.
[0009]
The present invention has been made to solve such a problem, and an object of the present invention is to provide an entry / exit management system capable of quickly knowing the history of entry and exit of an individual and the occupancy status. .

Hereinafter, the present invention will be described in detail based on embodiments. FIG. 2 is a system configuration diagram of an entry / exit management system showing an embodiment of the present invention. In the figure, reference numerals 2-1 to 2-8 denote card readers, which are arranged at the entrances and exits of the respective chambers 1-1 to 1-6 as shown in FIG. Reference numeral 3 denotes a center device, which includes a processing unit 3-1, a database 3-2, and a display / printing unit 3-3. Reference numeral 4 denotes an ID card for personal identification distributed to each individual.
[0012]
FIG. 3 is a flowchart showing the processing operation of the processing means 3-1. Hereinafter, operations specific to the present embodiment (operations for accumulating entry information and exit information in database 3-2 and operations for writing card information in database 3-2) will be described with reference to this flowchart.
[0013]
[Entering into conference room A]
In FIG. 6, for example, when entering the A conference room 1-6 from the laboratory 1-3, the ID card 4 for personal identification is set in the card reader 2-7 and the entry operation is performed.
[0014]
Then, the processing means 3-1 recognizes that an entry operation has been performed in the card reader 2-7 (YES in step 301), and uses the unique data (card number) written in the ID card 4 to use the card. The user's personal name (name of the room entrant) is specified, and the input information (entry time, room entry / exit status (room entry), and leader location (room entry location)) are recorded in the database 3-2 as a pair with the name of this room entrant (Step 302). In this case, as shown in FIG. 1A, the data is recorded in a storage record indicated by a record number (entry history record number) (1). The exit information is recorded in the same storage record as a pair with the entry information.
[0015]
The processing means 3-1 records a record indicating the recording position of the entry information in the database 3-2 in step 302 as a pair with the unique data written in the ID card 4 set in the card reader 2-7. The number (1) and the destination (the conference room A) are written into the database 3-2 as card information (step 303: see FIG. 1C).
[0016]
[Leave Room A]
When leaving the conference room 1-6, the door can be freely opened from the inside, so enter the laboratory 1-3, set the ID card 4 in the card reader 2-7, and perform the exit operation. . Then, based on the unique data written in the ID card 4 set in the card reader 2-7, the processing means 3-1 determines the record number written in the database 3-2 as a pair with the unique data. Is read out (step 304).
[0017]
If the record number and the entry destination are written in the card information of the exited person, it is determined that “the entry has been recorded” and the process proceeds to step 306. In this case, since the record number (1) and the entry destination (A meeting room) are written in the card information of the exited person, the process proceeds to step 306 in response to YES in step 305.
[0018]
In step 306, the processing unit 3-1 determines whether the exit location is the same as the entry destination, that is, the leader location recorded in the accumulated record in the database 3-2 indicated by the record number read in step 304 and the exit location. It is checked whether the entry destination written in the card information of the user is the same. In this case, the exit location (A conference room) and the entry / exit location (A conference room) are the same, so the process proceeds to step 307 in response to YES in step 306.
[0019]
In step 307, the processing means 3-1 sets the stored information in the database 3-2 indicated by the record number read from the card information of the exited person, that is, the accumulated record indicated by the record number {1}, as the exit information. The exit time, entry / exit status (exit room), and leader location (exit location: conference room A) are written (see FIG. 1B).
[0020]
Then, the processing unit 3-1 regards the laboratory 1-3 as a new entry location, and pairs the entry information with the personal name (name of the entry person) specified by the unique data written in the ID card 4. (Entry time, entry / exit status (entry), leader location (entry location: laboratory)) are recorded in the accumulation record indicated by record number {circle around (2)} in database 3-2 (step 308: FIG. 1 (a)). reference). The exit information is recorded in the same storage record as a pair with the entry information.
[0021]
Further, the processing unit 3-1 records, as a pair with the unique data written in the ID card set in the card reader 2-7, a record number indicating the recording position of the entry information in the database 3-2 in Step 308. (2) and the destination (laboratory), ie, the entry / exit (latest entry), are written in the database 3-2 as card information (step 309: see FIG. 1D).
[0022]
If there is no entry record in step 305, or if the exit location is different from the entry / exit destination in step 306, the entry information is written in the ID card 4 in the new storage record as "not entered". The exit information (exit time, entry / exit status (exit), and leader location (exit location)) is recorded as a pair with the personal name (name of the exit person) specified by the unique data (the record shown in FIG. 1A). No. (3)).
[0023]
FIG. 4 shows a display / printing example of the entry information and the exit information in the display / printing means 3-3. In this example, the entry information and the exit information stored as a pair in the accumulated record of the database 3-2 are displayed / printed. In FIG. 4, “****” indicates indefinite information, and it is considered that the entry operation was not performed when the entry was exited with “****”. If the exit is “****”, it means that the user is at the entry location and has not yet exited, or has entered another room without performing the exit operation.
[0024]
As can be seen from the display / print example of FIG. 4, in the present embodiment, since the entry information and the exit information are stored as a pair in the accumulated record of the database 3-2, the search processing at the time of display / print is simple. -As a high speed, it is possible to quickly know the history of individual entry and exit and the occupancy status. As a result, the current situation can be quickly grasped, and prompt responses can be made in the case of a call transfer or emergency. The entry information and the exit information may be displayed using the personal name as a search condition, or the search may be performed by specifying other conditions such as a leader location.
[0025]
Further, the occupancy time of each individual is calculated from the entry time included in the entry information recorded in the database 3-2 and the exit time included in the exit information, and the calculated occupancy time of each individual is calculated. The total time may be calculated for each predetermined period (every day, every month), and the total time of each individual may be displayed.
[0026]
For example, create individual entry records, occupancy records, and total occupancy time in rooms with high security levels such as radiation, laboratories handling dangerous materials, and information rooms handling confidential information. Accordingly, it is possible to make the person in charge grasp the behavior of the individual, and perform rotation of the staff, restriction of entry, and the like. In addition, any problems can be pointed out and improved, which is useful for personal safety management and health management.
[0027]
Further, the number of persons in each room may be calculated based on the entry information and the exit information recorded in the database 3-3, and the calculated number of persons may be displayed for each room. Good (see FIG. 5). By grasping the number of persons in the room, it is possible to apply the control to the air-conditioning control of each room or to give information to the control of the outside air damper and the like.
