Abstract

PROBLEM TO BE SOLVED: To provide the access controller and entry and existing management device which can make the signal processing of an information processor efficient while minimizing a rise in cost. SOLUTION: Even when a burglar prevention sensor 4 outputs a signal, the signal is not outputted to the information processor 20 unless a burglar prevention alert is set, but outputted to the information processor 20 for a certain time when the burglar preventive alert is started. Consequently, the amount of the signal sent to the information processor 20 is reduced, so the load on the information processor 20 is lightened to improve the responsiveness of the information processor 20. Further, the signal from a burglar preventive sensor 4 is outputted for a certain time and then it can be confirmed whether the signal from the burglar prevention center 4 is a burst or intermittent, so it can be decided whether the signal is sent due to temporary malfunction of the sensor or the wandering of a robber.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an access control device and an entry / exit management device suitable for unlocking control of doors, security monitoring, and the like.

[0002]

2. Description of the Related Art Conventionally, there has been an access control device for controlling door unlocking and crime prevention monitoring. FIG. 7 is a diagram showing a configuration of an entry / exit management device using such an access control device. In this figure, reference numeral 1 denotes an electric lock installed in the door 2, and unlocks the door 2 by supplying a control signal. A card reader 3 is composed of a card reading unit and a key input unit. The card reading unit is used for reading personal identification information (ID information) recorded on an ID card (not shown), and the key input unit is a crime prevention unit. Used to set alert start / cancellation. In this case, when the user performs the crime prevention warning start operation using the key input unit, the crime prevention warning start code is output. The card reader 3 is provided on the entrance side of the door or on both the entrance side and the exit side.

The information processing device 6 enters a crime prevention warning state by taking in the crime prevention warning start signal and sends an acceptance signal notifying that the crime prevention warning start signal has been received to the card reader 3 which has output this crime prevention warning start signal. .
The card reader 3 turns on the light emitting diode indicating the crime prevention state by taking in the acceptance signal. The information processing device 6 issues an alarm when the signal from the security sensor 4 is taken in during the security alert state. In this case, if the security warning start signal from the card reader 3 is not received, the alarm is not issued even if the signal from the security sensor 4 is taken in. The crime prevention sensor 4 detects not only a person but also an open / closed state of a window or a door. Especially, a person who detects a person is radiated from far infrared energy emitted from a room to be watched and body temperature of an intruder. A signal is output by detecting the difference with far-infrared energy.

A plurality of electric locks 1, a card reader 3 and a crime prevention sensor 4 are connected to the control panel 5. The control panel 5 monitors the output states of the electric lock 1, the card reader 3, and the crime prevention sensor 4 by, for example, a polling method, and takes in any signal output. In this case, when the control panel 5 reads the ID information from the card reader 3 after reading the code indicating the start of crime prevention warning from the card reader 3, the control panel 5 determines whether or not the ID information is registered in advance, and registers it. If it is determined that the information has been issued, a crime prevention warning start signal is sent to the information processing device 6 together with the ID information. On the other hand, when only the ID information is output from the card reader 3, it is determined whether or not the ID information is registered in advance, and if it is determined that the ID information is registered, the ID warning information and the crime prevention warning cancellation signal are sent. It is sent to the processing device 6. When the control panel 5 receives the signal from the security sensor 4, the control panel 5 sends the signal to the information processing device 6. Further, the control panel 5 monitors the open / closed state of the door and sends the result to the information processing device 6. The electric lock 1, the card reader 3, the crime prevention sensor 4, and the control panel 5 other than the information processing device 6 constitute an access control device.
A computer is mainly used as the information processing device.

[0005]

However, the above-mentioned conventional access control device has the following problems. (A) The card reader 3 reads an ID card, the security sensor 4 detects a person,
Further, since the result is sent to the information processing device 6 every time the open / closed state of the door is monitored, the information processing device 6 processes a large amount of signals. Therefore, the response of the information processing device 6 may be delayed and may be kept waiting. For example, when an employee of a tenant in an office building tries to leave the company and performs a crime prevention warning start operation using the key input unit of the card reader 3, if the information processing device 6 is performing another process, that process is performed. Until it ends, it does not send a reply signal informing that the crime prevention warning start signal has been received. Therefore, the employee must wait on the spot until the reply signal is sent. Such a delay in processing becomes more remarkable as the number of people entering the security area of the security sensor 4 increases or the number of card readers 3 installed increases.

(B) The above problems can be solved by providing a plurality of information processing devices 6 and performing distributed processing. However, if this is done, new problems arise in that the cost is high and a large installation space is required. Occurs.

Therefore, an object of the present invention is to provide an access control device and an entry / exit management device which can improve the efficiency of signal processing in an information processing device while suppressing an increase in cost to a minimum.

[0008]

In order to achieve the above object, the access control device according to the first aspect of the present invention reads the personal identification information recorded on the ID card, and then reads the read individual. It is determined whether or not the identification information is pre-registered, and if it is determined that the identification information is pre-registered, an access control device that controls an actuator such as an electric lock and outputs the read personal identification information Sensor output capturing means for continuously capturing signals output from each of the crime prevention sensors, setting means for setting crime prevention warning start / cancellation, and while the crime prevention warning cancellation setting is made by this setting means Even if a signal is output from the security sensor, it will not be output to the outside, and is constant if there is an input from the security sensor while the security alert start is set. And signal output means for outputting to the outside only during, characterized in that the provided.

According to this structure, even if a signal is output from the crime prevention sensor, the signal is not output to the outside while the security alert is being released, and is output to the outside for a certain period of time when the security alert is being started. Therefore, since the amount of signals flowing to the outside is reduced, the load on the information processing device that receives a signal from the security sensor and issues a security alarm is lightened, and the responsiveness is improved.

The access control device according to the second aspect of the present invention, after reading the personal identification information recorded on the ID card, determines whether or not the read personal identification information is registered in advance, In the access control device that controls the actuator such as an electric lock and outputs the read personal identification information when it is judged that it is registered in advance, the sensor output that continuously captures the signal output from each of the plurality of security sensors Capture means, setting means for setting the start / cancellation of crime prevention warning, signal input means for fetching a loop confirmation signal from the outside, and a crime prevention warning release from outside while the setting means is set. When a loop confirmation signal is sent, a signal from the security sensor designated by the loop confirmation signal among the plurality of security sensors Characterized in that a, a signal output means for outputting to the outside by a certain time.

According to this structure, when a loop confirmation signal is sent from the outside while the security alert is released, the signal from the security sensor designated by the loop confirmation signal from the plurality of security sensors is output for a certain period of time. It is output to the outside.
Therefore, unless the loop confirmation signal is sent while the security alert is released, the signal from each crime prevention sensor is not output to the outside at all, and even if the loop confirmation signal is sent, it is output only for a certain period of time. Therefore, the processing load of the information processing device that receives a signal from the security sensor and issues a security alarm is lightened, and the responsiveness is improved.

Further, for example, in a tenant having an office building with a large number of tenants, when the operation for starting the crime prevention warning is not performed even late at night, the output of the crime prevention sensor installed in the tenant is requested from the outside. If there is a person in the tenant, the security sensor installed in the tenant outputs a signal for a certain period of time when a loop confirmation signal is sent.By checking this signal from the outside, You can check if you are still there, have returned, or forgot the operation to start crime prevention. In this case, if there is a person, each time a person enters the warning area of the security sensor, an output can be obtained from the security sensor, so it can be seen that there are still people. On the other hand, if no person is detected, it is understood that the operation for starting the security alert is forgotten. Further, the security sensor detects the open / closed state of the door or window, and if the security sensor outputs the output, it can be understood that the door or window has been forgotten to be closed.

Further, when an abnormality from the security sensor is detected during the security alert, a loop confirmation signal is sent to enable confirmation of whether the signal from the security sensor is a sporadic one or an intermittent one. Therefore, it is possible to determine whether the sensor is operating temporarily or the bandits are wandering around.

The access control device according to the invention of claim 3 sends the access control device according to claim 2 and a loop confirmation signal for designating the security sensor which has started the security alert to the access control device. In addition, an information processing device that receives a signal from the security sensor via the access control device and displays the signal according to the state of the signal is provided. According to this configuration, when a crime prevention sensor in which the crime prevention warning is being started is designated for the access control device, a signal from the designated crime prevention sensor is sent from the access control device. In the information processing device, display is performed according to the signal from the security sensor sent from the access control device. Therefore, by checking the display according to the signal from the security sensor, it is possible to confirm whether there are people still in the tenant where the specified security sensor is installed, whether they have returned, or have forgotten the operation to start security alert. You can

B. Configuration of Information Processing Device (a) Configuration of Information Processing Device 20 FIG. 2 is a block diagram showing the configuration of the information processing device 20. In the figure, reference numeral 21 is an oscillating unit, which outputs a basic clock. Reference numeral 22 denotes a frequency divider, which divides the clock signal output from the oscillator 21 and outputs the clock signal required for this device. The clock signal from the frequency divider 22 is taken into the controller 23. An input / output interface 24 connects a pointing device such as a light pen 25 to the control unit 23. The input / output interface 24 connects the control panel 10 and the control unit 23. Reference numeral 26 is a key input unit such as a keyboard, and 27 is a display control unit, which displays the display data supplied from the control unit 23 on a monitor (not shown). Reference numeral 28 denotes an alarm sound generation unit, which generates an alarm sound when there is an intrusion while the security alert is started. A storage device 29 such as a hard disk device or a floppy disk device is used for recording data.
A ROM 30 stores a program for operating the control unit 23. Reference numeral 31 is a RAM, which is used in the operation of the control unit 23.

FIG. 3 is a diagram showing a display example on the monitor. As shown in this figure, a display unit 50 showing a plan view of each room (hereinafter referred to as tenant), a display unit 51 for displaying a crime prevention status and loop confirmation, and a display unit 52 for displaying a message are displayed. It In this figure, each tenant on the second floor is displayed. In the display unit 50, when an intrusion occurs in a tenant in which crime prevention warning is being started, red blinking is displayed as an alarm display. For example, when the tenant A is in the middle of crime prevention warning and an intrusion occurs in the tenant A, the alarm display unit 50A blinks in red. The display unit 51 includes a tenant name display area 51A for displaying a tenant name, a crime prevention warning start / cancel display area 51B, and a loop confirmation area 51C.

In this case, for example, when a crime prevention warning start signal is supplied from the control panel 10 while the crime prevention warning of the tenant A on the second floor is being started, the crime prevention warning start / cancel display area 51B corresponding to the tenant A lights up in green. (“●” is displayed). Due to this, the crime prevention warning is being started. When the security warning start is released, the green lighting of the security warning start / cancel display area 51B goes out (becomes "○"). Here, the crime prevention warning start setting is performed when the employee of the tenant A operates the card reader 3 to enter the crime prevention warning start code in an attempt to leave the company, and then reads the ID card.

On the other hand, the crime prevention warning start / cancel display area 51
When the display of B disappears, that is, when the security warning is released, the loop confirmation area 51C on the right side of the display is displayed.
When is clicked with the light pen 25, a loop confirmation signal designating the security sensor 4 installed in the tenant in which the security alert is released is sent to the control panel 10. As a result, a signal from the designated security sensor 4 is sent from the control panel 10, so that the loop confirmation area 51C lights up or blinks. In this case, if there is no person in the tenant and, for example, the window remains open, the security sensor 4 for detecting the open / closed state of the window remains in the on state,
The loop confirmation area 51C is turned on. On the other hand, if there is a person in the tenant, a signal is output every time a person enters the security area of the crime prevention sensor 4, so that the loop confirmation area 51C blinks. In this way, depending on the display state of the loop confirmation area 51C, is there still a person?
You can check at a remote location if there are no people and the window or door is still open. The information processing device 20 is generally installed in a manager's room.

Various messages are displayed on the display section 52. For example, if ID information, crime prevention warning release signal and message information are sent from the control panel 10, for example, "At 8:25 on June 19, 1995, Mr. Suzuki passes the card to the tenant A card reader on the second floor. Message is displayed. Further, when the ID information, the crime prevention warning start signal, and the message information are sent from the control panel 10, for example, a message "Mr. Sato started warning of the tenant A on the second floor at 23:15" is displayed. In addition, if there is an intrusion in a tenant that is on alert for crime prevention, for example, a message "A warning has been issued in tenant A on the second floor at 22:10 on June 20, 1995" is displayed.

(B) Main contents of control of the control unit 23 of the information processing apparatus 20 When coordinates of the loop confirmation area 51C are input, a loop confirmation signal designating the corresponding security sensor 4 is controlled via the input / output interface 24. It is sent to the board 10. When the ID information, the crime prevention warning start signal, and the message information are fetched through the input / output interface 24, the display of the crime prevention warning start / cancel display area 51B corresponding to the tenant who has started the crime prevention warning is turned on (“●” display). ).
Further, for example, a message "Mr. Sato has started warning the tenant A on the second floor at 23:15" is displayed on the display unit 52.

ID via the input / output interface 24
When the information, the crime prevention warning release signal, and the message information are taken in, the display of the crime prevention warning start / cancel display area 51B corresponding to the tenant that has been released from the crime prevention warning is erased ("○" is displayed). Further, for example, a message "Mr. Suzuki canceled the warning of the tenant A on the second floor at 8:25 on June 19, 1995" is displayed on the display unit 52. When a signal from the security sensor 4 is taken in via the input / output interface 24 while the security alert is started, the alarm display section 50A of the display section 50 corresponding to the tenant in which the security sensor 4 is installed blinks. Further, an alarm is generated and a message such as "A warning has been generated in the tenant A on the second floor at 22:10 on June 20, 1995" is displayed on the display unit 52.

When a signal from the security sensor 4 is taken in through the input / output interface 24 during the security alert cancellation, the loop confirmation area 51C corresponding to the tenant in which the security sensor 4 is installed is turned on or blinked. In this case, as described above, if there is no person in the tenant and, for example, the window remains open, the security sensor 4 for detecting the open / closed state of the window remains in the on state. Lights up. On the other hand, if there is a person in the tenant, a signal is output every time a person enters the security area of the crime prevention sensor 4, so the loop confirmation area 51C
Will blink. The sensor input section 11 and the control section 14 constitute a sensor output capturing means 100. The key input unit of the card reader 3 corresponds to the setting means. Further, the control unit 14 and the transmission unit 17 constitute a signal output unit 110 and a signal input unit 120, respectively.

C. Operation of Control Panel 10 FIGS. 4 and 5 are flowcharts showing the operation of the control panel 10. First, in step S10, it is determined whether or not there is a loop confirmation signal. If it is determined in this determination that there is a loop confirmation signal, the process proceeds to step S12, and it is determined whether or not the crime prevention sensor 4 designated by the loop confirmation signal is under the security alert release. If it is determined in this determination that the crime prevention warning is not being released, the process returns to step S10.
On the other hand, if it is determined that the security alert is being released, the process proceeds to step S14, and the process of transmitting the signal from the designated security sensor 4 to the information processing device 20 is started. Next, in step S16, it is determined whether or not a fixed time has elapsed. If it is determined that the predetermined time has not elapsed in this determination, the process returns to step S14. On the other hand, if it is determined that the fixed time has elapsed, the process returns to step S10.
As a result, a signal from the designated security sensor 4 is transmitted within a certain period of time.

If it is determined in step S10 that there is no loop confirmation signal, the process proceeds to step S18,
It is determined whether or not there is an output from the security sensor 4. If it is determined in this determination that there is an output from the crime prevention sensor 4, the process proceeds to step S20, and it is determined whether or not the crime prevention sensor 4 that has output has started crime prevention warning. In this determination, if it is determined that the crime prevention sensor 4 that has output is not the one in which the crime prevention warning is being started, the process returns to step S10. On the other hand, if it is determined that the security sensor 4 that has output has started the security alert, the process proceeds to step S22, and the process of sending the signal from the security sensor 4 to the information processing device 20 is started. Next, in step S24, it is determined whether or not a predetermined time has elapsed. If it is determined that the predetermined time has not elapsed in this determination, the process returns to step S22. On the other hand, if it is determined that the fixed time has elapsed, the process returns to step S10. As a result, a signal from the designated security sensor 4 is transmitted within a certain period of time.

If it is determined in step S18 that there is no output from the security sensor 4, the process proceeds to step S26 to determine whether or not there is a security alert start code.
That is, it is determined whether or not the card reader 3 has performed an operation for starting security alert. In this determination, if it is determined that the crime prevention warning start code is present, the process proceeds to step S28 to determine whether or not the ID information is present, that is, whether or not the ID card reading operation is performed. If it is determined that there is no ID information in this determination, the process returns to step S10. On the other hand, if it is determined that the ID information is present, the process proceeds to step S30, and it is determined whether the ID information recorded on the read ID card is registered in advance. If it is determined in this determination that the ID information is not registered in advance, nothing is done and the process returns to step S10.
On the other hand, if it is determined that the ID information is registered in advance, the process proceeds to step S32, and the ID information is sent to the information processing device 20. Then step S34
To send a crime prevention warning start signal, and in step S36, message information (for example, “June 20, 1995, 22:10).
An alarm occurred in Tenant A on the 2nd floor. ”).

If it is determined in step S26 that there is no crime prevention warning start code, the flow advances to step S38 to determine whether or not there is ID information, that is, whether or not only the ID card reading operation has been performed. If it is determined that there is no ID information in this determination, step S10
Return to On the other hand, if it is determined that the ID information is present, the process proceeds to step S40, and it is determined whether or not the ID information recorded in the read ID card is registered in advance. If it is determined in this determination that the ID information is not registered in advance, nothing is done and the process returns to step S10. On the other hand, if it is determined that the ID information is registered in advance, the process proceeds to step S42, and the ID information is sent to the information processing device 20. Then step S
A crime prevention warning release signal is transmitted at 44, and further step S46
Message information (for example, “June 19, 1995, 8: 2)
In 5th, Mr. Suzuki passed the card through the card reader of Tenant A on the 2nd floor ”).

D. Operation of Information Processing Device 20 FIG. 6 is a flowchart showing the operation of the information processing device 20. First, in step S60, it is determined whether or not there is a loop confirmation input. That is, it is determined whether or not the loop confirmation area 51C is clicked with the light pen 25.
If it is determined in this determination that there is a loop confirmation input, the process proceeds to step S62, and a loop confirmation signal for selecting the designated security sensor 4 is sent to the control panel 10. After performing this processing, the process returns to step S60. On the other hand, if it is determined that there is no loop confirmation input, the process proceeds to step S64.
It is determined whether or not the signal output from the security sensor 4 has been sent. If it is determined in this determination that the signal output from the crime prevention sensor 4 has been sent, step S6
At 6, it is judged whether or not the crime prevention warning is being started. If it is determined in this determination that the crime prevention warning is being started, the process proceeds to step S68 to display an alarm. That is, the alarm display unit 50A of the display unit 50 corresponding to the tenant in which the crime prevention sensor 4 that outputs the signal is installed blinks in red.

Next, in step S70, an alarm is generated,
Further, in step S72, a message (for example, "A warning has occurred in the tenant A on the second floor at 22:10 on June 20, 1995") is displayed on the display unit 52. After performing this processing, the process returns to step S60. If it is determined that the security alert is not being started in the determination of step S66, the process proceeds to step S74 to determine whether or not the security alert is being released. If it is determined in this determination that the crime prevention warning is not being released, the process returns to step S60. On the other hand, if it is determined that the security alert is being released, the process proceeds to step S76, and the loop confirmation result is displayed. For example, if the security sensor 4 that outputs a signal detects the open / closed state of the door, the loop confirmation area 51C is turned on. If the security sensor 4 that has output the signal detects a person, the loop confirmation area 51C is blinked every time a person enters the warning area.

If it is determined in the above step S64 that there is no signal from the security sensor 4, step S78
Then, it is judged whether or not there is a crime prevention warning start signal, ID information and message information. If it is determined in this determination that there is a crime prevention warning start signal or the like, the process proceeds to step S80 to display that crime prevention warning is being started. That is, the display of the crime prevention warning start / cancel display area 51B corresponding to the tenant in which the crime prevention warning has started has been turned on (“●” display). Next, in step S82, a message is displayed (for example, "2
At 3:15, Mr. Sato started warning the tenant A on the 2nd floor. ') After performing this processing, the process returns to step S60.

When it is judged in the above-mentioned step S78 that there is no crime prevention warning start signal or the like, the process proceeds to step S84, and it is judged whether or not there is a crime prevention warning cancellation signal, ID information and message information. If it is determined in this determination that there is a crime prevention warning release signal, etc., the process proceeds to step S86,
Displays that the security alert is being released. That is, the security alert start / cancel display area 51 corresponding to the tenant who has been released from the security alert
Turn off the display of B (“○” display). Next, step S8
8 to display a message (for example, “June 19, 1995”
At 8:25 on the day, Mr. Suzuki canceled the warning of Tenant A on the second floor ”). After performing this processing, step S60
Return to If it is determined that there is no crime prevention warning release signal in the determination in step S84, the process proceeds to step S90,
Perform other processing. After performing this process, step S
Return to 60.

Thus, in this embodiment, the security sensor 4
Even if the signal is output from, the information is not output to the information processing device 20 if the security alert is being released, and is output to the information processing device 20 for a certain period of time if the security alert is being started. Therefore, since the amount of signals flowing to the information processing device 20 is reduced, the load on the information processing device 20 is lightened and the responsiveness is improved. In addition, by outputting the signal from the security sensor 4 for a certain period of time, it is possible to check whether the signal from the security sensor 4 is a sporadic one or an intermittent one. It is possible to determine whether or not.

Further, the information processing device 20 is activated while the security alert is released.
When the loop confirmation signal is sent from the information processing apparatus 2 for a certain period of time, the signal from the crime prevention sensor 4 designated by the loop confirmation signal among the plurality of crime prevention sensors 4 is sent.
Send to 0. The information processing device 20 takes in the signal and displays the state of the signal in the loop confirmation area 51C. In this case, the security sensor 4 detects the open / closed state of the window or door, and if these are left open, the loop confirmation area 51C is turned on. If the security sensor 4 detects a person, the loop confirmation area 51C will be in a blinking state because there is an output every time a person enters the warning area.

Therefore, while the security alert is released, no signal from each security sensor 4 is output to the outside unless a loop confirmation signal is sent, and even if a loop confirmation signal is sent, it is only for a fixed time. Since the information is not output, the processing load on the information processing device 20 is reduced, and the responsiveness is improved.
Further, for example, in a tenant having an office building with a large number of tenants, the output of the security sensor 4 installed in the tenant is output from the information processing device 20 when the operation for starting the security alert is not performed even at late night. When the requested loop confirmation signal is sent, if there is a person in the tenant, the security sensor 4 installed in the tenant outputs a signal for a certain period of time. Therefore, by checking this signal on the information processing device 20 side, , It is possible to confirm whether there are people still in the tenant or have returned, or forgot the operation to start crime prevention warning.

In this case, if there is a person, an output can be obtained from the crime prevention sensor 4 every time a person enters the warning area of the crime prevention sensor 4, so it can be seen that there is still a person. On the other hand, if no person is detected, it is understood that the operation for starting the security alert is forgotten. Further, the security sensor 4 detects the open / closed state of the door or window, and if the security sensor 4 continues to output, it can be seen that the door or window has been forgotten to be closed.

The present invention is not limited to the above embodiments, but various embodiments are possible within the scope of the object of the present invention. Specifically, the following may be performed. (A) In the above-described embodiment, when the information processing device 20 performs the loop confirmation, the plurality of security sensors 4 are designated one by one. However, by providing a group setting function, one of the security sensors 4 is designated. You may make it possible to specify for all the security sensors 4 set in a group by performing an input (click operation with a light pen) to specify. (B) In the above-described embodiment, the information processing apparatus 20 cannot be set to start / cancel the crime prevention warning on the control panel 10, but this information processing apparatus 20 may be set. Further, not only the crime prevention warning start / cancel setting for one crime prevention sensor 4 but also the group setting may be performed as in the case of loop confirmation.

(C) In the above embodiment, the information processing device 20
Although various messages are displayed in above, they may be notified by voice or may be combined. (D) In the above embodiment, the light pen was used as the pointing device, but it is of course possible to use a mouse, a trackball, a tablet or the like.

According to the access control device of the first aspect of the present invention, even if a signal is output from the security sensor, no output is made to the outside if the security alert is being released, and is constant if the security alert is being started. Since only the time is output, the amount of the signal flowing to the outside is reduced, the processing load on the information processing device for receiving the signal from the security sensor 4 and issuing the security alarm is lightened, and the responsiveness is improved. Moreover, since the amount of signals flowing to the outside is reduced, the efficiency of information processing is improved, and it is not necessary to provide a plurality of information processing devices. Also, by outputting the signal from the security sensor for a certain period of time, it is possible to confirm whether the signal from the security sensor is a sporadic one or an intermittent one. You can determine if you are wandering.

According to the access control device of the second aspect of the present invention, when a loop confirmation signal is sent from the outside while the security alert is released, the security sensor designated by the loop confirmation signal is selected from the plurality of security sensors. Since the signal from is output to the outside for a certain period of time, the signal from each security sensor is not output to the outside at all unless a loop confirmation signal is sent while the security alert is released. Will be output only for a certain period of time,
The processing load of the device that receives a signal from the security sensor and issues a security alarm is lightened, and the response is improved. Moreover, since the amount of signals flowing to the outside is reduced, the efficiency of information processing is improved, and it is not necessary to provide a plurality of information processing devices. In addition, since the security sensor outputs a signal for a certain period of time, by checking this signal with the device, it is possible to check whether there are people in the room where the security sensor is installed, whether they have returned, or operations to start security alert. You can check if you have forgotten.

According to the entry / exit management apparatus of the third aspect of the present invention, a security sensor that is in the beginning of security warning is designated for the access control apparatus, and a signal from the designated security sensor is sent from the access control apparatus. When it was sent, I displayed it according to the signal, so I wonder if there are people still in the room where the specified security sensor is installed, if I returned or I forgot to start the security alert. Can be confirmed. In this case, if a person is still in the room where the designated security sensor is installed, a signal is output from the security sensor every time a person enters the security area of the security sensor. This makes it possible to confirm that there is a person in the room in which the designated security sensor is installed.
