Description

The utility model relates to the field of electromagnetic locking devices and can be used to lock residential and industrial buildings.

Known intercom-locking devices of the entrance door of the building containing an electromagnetic lock, a call block, a key and intercoms with remote control of the lock (see, for example, the AS of the USSR No. 727833 class E05B 47/00, 1978, PM RF No. 28714 CL EV 05/47, 2003). The disadvantages of the known devices include the lack or insufficient protection of residential and industrial premises from unauthorized entry of unauthorized persons into them.

Closest to the proposed device in technical essence is the intercom-lock device of the front door of the building, containing an electromagnetic lock, a call block, a key and intercoms with remote control of the lock (see. PM RF №22677 cl Е05В 47/00, 2002) .

The disadvantages of the described device include the lack of protection against penetration into the storey rooms of the entrance, and as a result of this - the penetration into the apartments of persons who entered the entrance together with the residents or after unlocking the entrance door from any apartment.

The objective of the utility model is to eliminate this drawback.

The problem is solved due to the fact that in the well-known intercom-lock device of the entrance door of the building, containing an electromagnetic lock, a call block, a key and intercoms with remote control of the lock, a control and switching unit is installed on each floor of the building, to which intercoms are connected , reed switch of the hall door, volumetric sensor of the hall room, sound emitter, siren, electronic key reader, and the outputs of all control and switching units, via the receiver cable network, connected to the access control unit, to which the information panel and the concierge desk are connected, connected to the call unit and the electromagnetic lock.

The described device, when unauthorized persons enter the staircase together with the tenants or after unlocking the entrance door from an apartment, and then when the door of the floor hall is cracked, generates an alarm signal that arrives both in the hall room and in the access control block, which prevents an outsider face further penetration into the apartment.

The drawing schematically shows the proposed device.

The intercom-lock device of the entrance door of the building contains an electromagnetic lock 1, a call block 2, which includes a key code determination unit and a switching unit (not shown in the drawing), a key 3 and intercoms with remote control of the lock (not shown in the drawing) . On each floor of the building there is a control and switching unit 4 (1 ... n), where n is the floor number), to which intercom communication devices for the apartments of this floor are connected, a reed switch 5 of the hall door, a volume sensor 6 of the hall room, an audio emitter 7, siren 8, electronic key reader 9, alarm button 10. At the entrance of the building there is an access control unit 11 connected to the outputs of all control and switching units 4 (1 ... n) through the cable trunk network, information panel 12 and the concierge desk 13, connected to call block 2 and ele with magnetic lock 1. The access control unit 11 is equipped with a built-in uninterruptible power supply unit and has outputs for connecting a digital information storage device and a security dispatcher console.

The proposed device operates as follows:

Initial conditions for the operation of the device: all doors of the protected halls are locked with a mechanical lock, and the access door with electromagnetic lock 1. The device, using floor control and switching units 4 (1 ... n), constantly monitors the closed state of the floor hall doors, and using the access control unit 11 - the integrity of the trunk cable network and floor blocks 4 (1 ... n).

The tenant enters the entrance using his own electronic key 3, individual for each tenant, and the visitor - after the access door is opened by the subscriber of the apartment he dialed. The individual key used (or the number of the dialed apartment) used to enter the staircase is transmitted digitally on the trunk cable network to floor control and switching units 4 (1 ... n). The control and switching unit of floor 4 (1 ... n), on which the apartment is located (dialed, or to which this key is assigned), for a predetermined time, disarms its hall.

The tenant (or visitor) must, during the time set by the operation of the device, go up to the floor and enter the hall, opening the hall door with a mechanical key (the visitor is let into the hall by the tenant of the apartment, to whom the visitor came by opening the hall door from the inside). At the same time, the fact of entering the floor hall from the outside (for the tenant), or opening the floor hall from the inside (for the visitor) and closing the hall door with the floor

block 4 (1 ... n) is perceived as the completion of the passage event, and the hall of this floor is armed.

If a visitor enters the hall of another floor (by “breaking” the hall door), then floor block 4 (1 ... n) will record this event by the operation signals of the reed switch 5 of the hall door and volume sensor 6 and will form on the floor first, within 30 seconds, the warning sound signal that is sent to the sound emitter 7. If within 30 seconds the warning signal on the floor is not turned off using the electronic key 3 attached to the electronic key reader 9, then the floor unit 4 (1 ... n) will generate alarm and send it to and the floor siren 8, and via the trunk cable network to the access control unit 11. The access block 11 will transmit information on an alarm event to the information panel 12 and to external lines (digital information storage device, dispatcher console, private security post).

If the tenant leaves his hall, closing the door behind him, then the floor block 4 (1 ... n) will generate a signal to exit the hall and for the time specified by the operation algorithm will disarm this hall. Information on disarming the hall via the trunk cable network is sent to driveway 11. If the tenant returns (entrance to the hall from the outside) within a specified time, then at the return entrance to the hall, floor block 4 (1 ... n) considers this event completed and will set this floor on guard. If the tenant does not return to the hall within the specified time, then after this time the floor block 4 (1 ... n) will arm this hall (if the hall door is closed). If the tenant returns to the hall after a specified time, a warning sound signal will be generated on the floor block for 30 seconds, which will be transmitted to the sound emitter 7. The tenant, using his electronic key 3, must disconnect on his floor within 30 seconds a warning signal by attaching your key to the reader 9. In this case, an alarm signal to the floor siren 8, to the access block 11 and to external circuits will not be received, and the hall of the floor will be armed.

If the tenant does not close the door when leaving the hall, then floor block 4 (1 ... n) will generate a signal to exit the hall and for the time specified by the operation algorithm will disarm this hall. Also, a tonal sound signal of the open state of the door of the hall will be generated on the floor by the floor block 4 (1 ... n), which is transmitted to the sound emitter 7, warning the residents of the floor about the need to close the door. Information about the disarming of the hall is transmitted to driveway 11. If the tenant returns within the specified time to the hall and closes the door, the exit from the hall

floor block 4 (1 ... n) is considered completed and the hall is armed. If the tenant does not return to the floor hall within the specified time (the door of the hall remains open), then floor block 4 (1 ... n) will generate a signal for the door to be open and transmit it via the cable trunk network to drive block 11. From the drive block 11, the signal of the open state of the hall door will go to the information panel 12, and, if necessary, to external lines. The hall floor will be armed only after closing the hall door.

If the tenant of the entrance violates the “correct” sequence of his actions (for example, he enters the hall of the floor after a specified time after entering the entrance, or enters the entrance with another tenant, that is, by someone else's key), then when the tenant enters his hall, floor unit 4 (1 ... n), for a period of 30 seconds, generates a warning sound signal on the floor and sends this signal to the sound emitter 7. The tenant, using his electronic key 3, attaching it to the reader 9 of the electronic key on his floor should disable warning a signal, which in this case will not arrive at the access block 11 and to external circuits.

In case of emergency, on the floor control and switching blocks 4 (1 ... n) there is a button 10 "unconditional alarm", after clicking on which, the alarm signal is sent to the access control block 11 and, if necessary, to external circuits.

The floor control and switching unit 4 (1 ... n) constantly monitors the lines of the apartment intercoms and, if a call signal from the apartment appears on one of them, generates a call signal to the concierge and connects the concierge desk 13 to this apartment for two-way communication of the tenant with the concierge.

The floor control and switching unit 4 (1 ... n) has the ability to turn on / off the video camera installed on the floor upon a signal from the concierge.

The access control unit 11 constantly monitors the integrity of the trunk cable network lines and floor control and switching units 4 (1 ... n) and, if a malfunction is detected, issues an alarm to the information panel 12 and to external lines.

The floor control and switching unit 4 (1 ... n) is made on a microcontroller with switching elements of the input and output circuits, to which external standard floor sensors and devices are connected.

The access control unit 11 is made on a microcontroller with switching elements of the input and output circuits. The access control unit 11 provides the input signals from the concierge desk 13 and the call unit 2 to the receiver cable network to the floor units 4 (1 ... n), the reception of information from the floor units 4 (1 ... n), the processing of these data by a given algorithm and the transfer of necessary information to external devices. The access control unit 11 constantly monitors the integrity of the trunk cable network lines and floor control and switching units 4 (1 ... n) and, if a malfunction is detected, issues an alarm to the information panel 12 and to external lines.

The access block 11 includes an uninterruptible power supply, from which power is supplied to all blocks of the intercom and lock device.

The use of the proposed device allows to prevent unauthorized access of unauthorized persons to the floor premises of the entrance, creating an additional security barrier in front of the apartments.
