The present invention relates to an entry / exit management technique, and more particularly to a technique effective when applied to entry / exit management in a complex room configuration.
[0002]
[Prior art]
In entrance / exit management using a card with a unique ID code, the following entrance / exit management is required when performing entrance / exit management such as anti-pass back-through control that requires card reading in both entrance and exit. Can be considered. In other words, if you enter the room by reading the card with the entry card reader, the controller that manages the card reader will be in the room when you use the card reader for reading the card at the first use or when you leave the room in the past. If it is not in the room, the electric lock is unlocked to allow entry, and if it is in the room, the electric lock remains locked and entry is prohibited.
[0003]
Also, when leaving the room, let the card reader read the card, and before entering the room, read the card with the card reader for entry and enter the room to make a decision in the room and the control device, if you are in the room, The electric lock is unlocked and the room is allowed to leave, and if it is not in the room, the electric lock is kept locked and the room is not allowed to leave.
[0004]
Conventionally, the entry / exit of each card holder or the like has been determined by grasping the occupancy status as described above.
[0005]
[Problems to be solved by the invention]
In the case of facilities consisting of multiple rooms, if you want to manage entry / exit via the entrance / exit route, depending on which card reader you used to read the card at the time of entry / exit, permission to unlock the electric lock for entering / exiting and Necessary to do so.
[0006]
However, in the above-described conventional entrance / exit management method based on the occupancy status, since it is not possible to determine which entry card reader has entered the room, it is possible to use a plurality of card readers and dynamically There was a technical problem that entrance / exit management was not possible.
[0007]
An object of the present invention is to provide an entrance / exit management technique capable of arbitrarily setting a plurality of entrance / exit routes in a plurality of room configurations.
[0008]
Another object of the present invention is to provide an entrance / exit management technique capable of arbitrarily setting a plurality of entrance / exit routes for a plurality of card IDs in a plurality of room configurations.
[0009]
Another object of the present invention is to provide an entrance / exit management technique capable of arbitrarily setting a plurality of entrance / exit routes for each of a large number of card IDs without causing a large information communication load.
[0010]
[Means for Solving the Problems]
In the present invention, authentication by a card reader is performed by a combination of an ID code assigned to each card and an unlock flag set for each card and at least one of each card reader. Various entry / exit management is realized by determining permission and non-permission and dynamically changing the setting state of the unlocking flag as necessary.
[0011]
More specifically, as an example, a card reader having a collation determination function by card, and a determination function by an unlocking flag for setting unlocking permission and non-permission of the electric lock assigned to each card, and the card reader An entry / exit management system is configured by a controller that is connected and collects the ID code of the card from the card reader, performs determination processing, and sets / controls the unlock flag assigned to each card with respect to the other card reader. It is. The control device can set the unlock flag assigned to the card based on the condition set from the card reader that has read the card and the ID code of the read card. This setting condition can be set for each ID code.
[0012]
According to the present invention, in the entrance / exit management using a card and a card reader, the entrance / exit conditions can be dynamically changed according to the place where the entrance is made. Entry / exit management such as setting and judgment of various entrance routes can be performed. Moreover, since the determination conditions can be set for each card ID, the entrance / exit management can be set under the conditions for each user. That is, after the card reader reads each card, the next valid card reader is designated, so that the condition setting is simplified. In this way, it is possible to construct an entrance / exit management system that can manage various entrance / exit routes in a building having a complicated room configuration.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
FIG. 1 is a block diagram showing an example of the configuration of an entrance / exit management system according to an embodiment of the present invention.
[0015]
In the entrance / exit management system of the present embodiment, a plurality of card readers such as card reader # 0 (102) and card reader # 1 (106) are connected to the control device 101 via the communication line 105 and the communication line 108. It has a connected configuration.
[0016]
Each of the plurality of card readers 102 and 106 has an unlock flag 104 and an unlock flag 107 and is managed from the control device 101 by a card reader number. As described later, the ID code of the read card 103 is The electric lock is unlocked from the collation determination result and the values of the unlock flags 104 and 107 held by each.
[0017]
The user causes the card reader # 0 (102) to read the card 103 having a unique ID code, and if the result of the collation determination is permitted, the user unlocks the electric lock 109 to enable entry / exit. If the result of the collation determination is not permitted, the electric lock 109 is locked to make entry / exit impossible.
[0018]
Next, a determination processing method in the card reader # 0 (102) will be described. The card reader # 0 (102) is caused to read the card 103 with the ID code “ID1”. The ID code verification process is performed inside the card reader # 0 (102). If the ID code “ID1” is permitted after the collation determination processing, it is determined from the unlocking flag 104 whether the unlocking flag corresponding to the ID code “ID1” is ON or OFF. When the ID code is permitted and the unlock flag is ON, the electric lock 109 is unlocked. When the ID code is not permitted and the unlock flag is OFF, the electric lock 109 is locked.
[0019]
Next, the card reader # 0 (102) notifies the control device 101 of the ID code “ID1” of the card 103 read through the communication line 105.
[0020]
The control device 101 includes an unlocking flag database 111, a plurality of entry / exit sequence tables 115, an entrance / exit sequence table 116, and an entrance / exit sequence table 117. The card reader # 0 (102) or card reader # 1 ( 106) The unlock flag is set from the ID code notified from 106).
[0021]
The unlock flag database 111 includes an ID code 112, an entrance / exit sequence table number 113 for identifying one of the entrance / exit sequence tables 115 to 117 corresponding thereto, and an unlock flag 114 currently set in the card reader. Has been.
[0022]
The entry / exit sequence table 115, 116, 117 includes information for setting which other card reader unlock flag is to be turned on or off for the card reader that has read the card 103, and Has the presence or absence of changes. For example, in the entrance / exit sequence table 115, 116, 117, each flag is composed of 2 bits and can be defined as 00 = OFF, 01 = ON, 10 = no change, and the like. There are a plurality of entry / exit sequence tables 115 to 117 corresponding to the number of types of entry / exit routes, and can be individually assigned to each ID code of each card 103.
[0023]
It is assumed that the unlock flag in the unlock flag database 111 and the entry / exit sequence table 115, 116, 117 is OFF when “0” and ON when “1”.
[0024]
When the unlock flag is rewritten, the control device 101 sets the unlock flag 104 or the unlock flag 107 to the card reader # 0 (102) or the card reader # 1 (106) through the communication line 105 or the communication line 108. Set.
[0025]
An example of the action (access control) in the entrance / exit management system of the present embodiment configured as described above will be described with reference to the flowcharts of FIGS.
[0026]
First, in step S1, the card reader # 0 (101) is caused to read the card 103. The card reader # 0 (101) determines whether the card 103 is a permission card in step S2. If the determination result is not permitted, the electric lock 109 remains locked in step S19, and entry / exit is not permitted. If it is determined in step S2 that the card is a permitted card, it is determined in step S3 with reference to the unlocking flag 104 whether the ID code unlocking flag of the card 103 is ON or OFF. If the unlock flag is OFF, the electric lock 109 remains locked in step S19. If the unlock flag is ON, the electric lock 109 is unlocked in step S4 and entry / exit is permitted.
[0027]
In step S5, the card reader # 0 (102) notifies the ID code “ID1” read in step S1 to the control apparatus 101 through the communication line 105.
[0028]
In step S <b> 6, the control device 101 searches the ID code “ID1” from the ID code 112 of the card in the unlock flag database 111. If “ID1” is found in the search result of the ID code in step S6 in step S7, “▲” is set as the entry / exit sequence table number 122 assigned to the ID code “ID1” from the entry / exit sequence table number 113 in step S8. 1 ▼ ”.
[0029]
Next, in step S9, the card reader # 0 is searched from the card reader number 118 of the entry / exit sequence table 115 (1), and the unlocking flag setting value 119 of each card reader is searched with the card reader # 0. The unlock flag setting value 120 when the card 103 is read is read. The unlock flag 121 in the ID code “ID1” of the card 103 is read from the unlock flag 114 of the unlock flag database 111. In step S10, the unlocking flag setting value 120 is compared with the current unlocking flag 121, and in step S11, an unlocking flag having a change with respect to the current unlocking flag 121 is extracted. In step S12, the content of the unlock flag setting value 120 is copied to the current unlock flag 121.
[0030]
In this case, the unlock flag is changed only for the card reader # 1. In step S13, the control device 101 notifies the card reader # 1 (106) of the ID code “ID1” and the unlock flag (only the data of the changed portion in this embodiment) through the communication line 108. In step S14, the card reader # 1 (106) rewrites the unlocking flag 107, and turns on the unlocking flag in the ID code “ID1”.
[0031]
In step S15, the card reader # 1 (106) is caused to read the card 103 with the ID code “ID1”. In step S16, ID code verification processing is performed inside the card reader # 1 (106). If not permitted, the electric lock 110 remains locked in step S20 and entry / exit is not permitted. If it is determined in step S16 that the card is a permitted card, it is determined in step S17 with reference to the unlocking flag 107 whether the ID code unlocking flag of the card 103 is ON or OFF. If the unlock flag is OFF, the electric lock 110 remains locked in step S20. If the unlock flag is ON, the electric lock 109 is unlocked in step S18 to permit entry / exit.
[0032]
As described above, in the case of the entrance / exit management system of the present embodiment, the control device 101 is connected to a plurality of connected card readers triggered by a notification from the card reader that has read the card 103. By dynamically setting the unlocking flag, it is possible to control permission or disapproval of entry / exit.
[0033]
Further, when the unlocking flag is transmitted and changed from the control device 101 to the plurality of card readers 102 and 106, only the changed part is selectively transmitted, so that the communication line 105 and the communication line can be reduced by reducing the flag data. 108 and the load on the control device 101 and the card readers 102 and 106 can be reduced. This is extremely effective when applied to a large-scale system having a large number of cards 103, that is, the number of users and card readers, that is, a large number of entrances and rooms.
