SOLUTION: In the event of a fire, a fire notification system 1 determines whether or not a security sensor 4 is in an operating state. The presence or absence of a person in the room is confirmed, and the result is added to a signaling signal for notifying that a fire has occurred, and transmitted to the access control system 10. On the other hand, upon receiving the notification signal to which the absence information is added, the entry / exit management system 10 locks the electric lock 13 in a room where no one is present.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an access control system and a fire notification system.

[0002]

2. Description of the Related Art There has conventionally been a fire notification system provided with a function for detecting a fire and an intrusion. In the event of a fire, this type of fire alarm system sounds a bell that indicates the occurrence of a fire and notifies the management room and fire department. It is to report. In particular, if an entry / exit management system is also installed, a transmission signal for informing the entry / exit management system of the occurrence of a fire is sent when a fire occurs. Upon receiving the notification signal indicating the occurrence of a fire, the access control system unlocks the electric lock installed in each room so that people in the room can easily evacuate. Incidentally, as an access control system for unlocking in the event of a fire, there is, for example, JP-A-7-26810.

[0003]

However, the above-mentioned conventional access control system has the following problems. That is, since all electric locks are unlocked based on a transfer signal from the fire notification system when a fire occurs, a person who knows this may intentionally start a fire and steal. In addition, when the electric lock is in the unlocked state, when the door of the burning room is opened, air suddenly flows in, and the fire explosively burns up, possibly causing serious burns. The explosive burning of fire due to the rapid inflow of air is called flashback.

Accordingly, an object of the present invention is to provide an entry / exit management system and a fire notification system that lock an electric lock in a room where no one is present when a fire occurs to prevent entry into the room.

[0005]

The concept of the present invention will be described below. In the fire notification system, if the human body detection means is not in operation at the time of the fire, it is forcibly activated and checks for the presence of people in each room,
The result is added to a signaling signal notifying that a fire has occurred, and sent to the access control system. When the entry / exit management system receives the notification signal to which the presence or absence of a person in each room is added, the electric lock of the absent room is selectively locked. Further, when a person is present at the present time and later becomes absent, the electric lock in the room is locked by a transfer signal transmitted again from the fire notification system. The electric lock allows manual unlocking / locking from inside the room.

[0006] Therefore, when a fire occurs, it is impossible to enter an absent room. Therefore, even if a person intentionally starts a fire and tries to enter the room, it is possible to prevent the entry. Further, even if a fire occurs in an absent room, it is not possible to enter the room, so that burns due to flashback can be prevented beforehand.

According to the first aspect of the present invention, there is provided an access control system for unlocking / locking a door, input means for inputting user identification information, and a fire alarm system. Receiving means for receiving a transfer signal; and controlling the electric lock based on the identification information input by the input means, wherein the absence signal is added to the transfer signal received by the receiving means. Is provided with control means for locking all electric locks in a room where no one is present based on the absence information.

According to a second aspect of the present invention, the electric lock can be manually unlocked / locked from inside a room. The fire notification system according to the invention according to claim 3, wherein the fire detection means for detecting a fire, a human body detection means for detecting the presence or absence of a person, and the human body detection means operating when the fire detection means detects a fire. If not, control means is forcibly set to an operation state, confirms the presence or absence of a person in each room, and sends a transfer signal to which the absence information is added to the entry / exit management system based on the result.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an embodiment of an access control system and a fire notification system according to the present invention. Hereinafter, the fire notification system and the access control system will be described in this order.

A. Configuration of Fire Notification System 1 The fire notification system 1 of the present embodiment includes a plurality of fire detectors 2, a transmitter 3, a security sensor 4, and a receiver 5. The fire detector 2 is installed on the ceiling of each room or corridor in the building, and the security sensor 4 is installed on the ceiling of each room. In addition, the transmitter 3 is installed on the wall of each part of the corridor. The fire detector 2 outputs a fire signal when it detects heat or smoke, and the transmitter 3 outputs a fire signal when a push button is pressed. The security sensor 4 detects a human body using far infrared rays, and outputs an alarm signal when a human body is detected.

When a fire signal from the fire detector 2 is input to the receiver 4, if the security sensor 4 is not in the operating state, the receiver is forcibly set in the operating state (alert state) to check for the presence of a person in the room. . After confirming the presence or absence of a person in the room, absence information is added to a transfer signal that indicates the occurrence of a fire, and the transfer signal is transmitted to the access control system 10 via the transmission interface 7. Further, it sends a notification signal notifying the occurrence of a fire to a management device (not shown).

B. Configuration of the entry / exit management system 10 The entry / exit management system 10 includes a plurality of entry / exit management control panels 11.

The control unit 20 inputs a transfer signal from the receiver 5 of the fire notification system 1 via the input interface 14. Further, it outputs a locking signal or an unlocking signal to the electric lock 13 via the output interface 15. Further, an unlock confirmation signal or a lock confirmation signal from the electric lock 13 is input through the input interface 16, and further, a door open signal or a door close signal from the electric lock 13 is input. When a password input from the operation panel 12 is input, the password is displayed on the display unit 19. Then, it is determined whether or not the captured personal identification number is stored in the storage unit 17. If it is determined that the personal identification number is stored, the state of the electric lock 13 is determined. West,
If it is locked, it is unlocked. On the other hand, if it is determined that the password is not the one stored in the storage unit 17, no processing is performed.

Further, the control unit 20 controls the fire alarm system 1
When a notification signal notifying of the occurrence of a fire and the absence of a fire is received from the receiver 5, the lock signal is output to the electric lock 13 in the empty room. In this case, if the room in which the person is present is no longer present, a lock signal is output to the electric lock 13 in that room by the transfer signal from the fire notification system 1. The electric lock 13 is provided with a solenoid coil 25 as shown in FIG.
And an unlock / unlock detection circuit 26 and a door open / close detection circuit 27. The solenoid coil 25 performs locking / unlocking. The lock / unlock detection circuit 26 detects a locked state and an unlocked state, and outputs a lock confirmation signal when the lock state is reached, and outputs an unlock confirmation signal when the lock state is detected. The door open / close detection circuit 27 detects the open / closed state of the door, and outputs a door open signal when the door is open, and outputs a door close signal when the door is closed.

C. Operation of Fire Notification System 1 FIG. 4 is a flowchart showing the operation of the fire notification system 1. First, it is determined in step S10 whether or not a fire has occurred. If it is determined that a fire has not occurred, this step is repeated. On the other hand, if it is determined that a fire has occurred, the process proceeds to step S12, in which all the security sensors 4 are forcibly set to the operating state. That is, the state is alert. After performing this processing, it is determined in step S14 whether there is a room that is absent. If it is determined that there is no room that is absent, the process returns to step S12. When the determination is made, the process proceeds to step S16, where the absence signal is added to the notification signal indicating the occurrence of the fire and output. After performing this process, the process ends. In addition,
Since this process is repeatedly performed at an extremely short time interval, if there is a person at present, a signaling signal notifying the room is output if the person is not present.

D. FIG. 5 is a flowchart showing the operation of the entry / exit management system 10. First, in step S30, it is determined whether there is an electric lock 13 in an unlocked state. This judgment is
This is performed for all the electric locks 13 controlled by the access control system 10. In this determination, if it is determined that there is no unlocked electric lock 13, this step is repeated. In contrast, the electric lock 13 in the unlocked state
If it is determined that there is, the process proceeds to step S32, and it is determined whether or not there is a signaling signal to which absence information is added.

In this determination, if it is determined that there is no broadcast signal to which absence information is added, this step is repeated.
On the other hand, if it is determined that there is a notification signal to which the absence information has been added, the process proceeds to step S34, and the electric locks 13 of all the absent rooms are locked. After performing this process, the process proceeds to step S36 to determine whether an unlocking operation has been performed from the inside of the room where the electric lock 13 is locked. In this determination, if it is determined that the unlocking operation has not been performed from the inside of the room, this step is repeated, and if it is determined that the unlocking operation has been performed, the electric lock 13 in the room is unlocked in step S38. After performing this process, the process ends. Since this process is also repeated every very short period, if there is an electric lock 13 that is absent and in an unlocked state, the locking control is performed on the electric lock 13.

As described above, in this embodiment, when a fire occurs, the fire alarm system 1
It is determined whether or not the room is in the operating state.If it is determined that the room is not in the operating state, the state is forcibly operated and the presence or absence of a person in the room is checked. Ingress / egress management system 1 in addition to the notification signal
Send to 0. On the other hand, upon receiving the notification signal to which the absence information is added, the entry / exit management system 10 locks the electric lock 13 in a room where no one is present. Further, even if the person is in the room where the person is currently located, the electric lock 13 in the room is locked by a notification signal from the fire notification system 1 when the person disappears after that.

Therefore, when a fire occurs, it is impossible to enter a room where no one is present, so that even if there is a person who intentionally starts a fire and tries to enter the room, the invasion can be prevented. Also, even if there is a fire in a room where there are no people,
Since the door of the room cannot be opened, burns due to flashback can be prevented beforehand.

In the above-described embodiment, the electric lock 13 is used as the door locking / unlocking means. However, a motor lock or an automatic door may be used. Further, in the above-described embodiment, the electric lock 13 is controlled by inputting a password from the operation panel 12 as a key, but a card reader may be used instead of the operation panel 12. In this case, there are magnetic stripe type card readers and non-contact type card readers that handle cards having a function of transmitting ID information.
