Description

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

Known intercom-locking devices 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, for example, AS USSR No. 727833 class E05B 47/00, 1978, PM RF No. 28714 class ЕВВ 47/00, 2003; PM of the Russian Federation No. 22677 class Е05В 47/00, 2002). 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 entrance door of the building, containing an electromagnetic lock, a call block, an electronic key, intercom devices with remote control of the lock and control and switching units on each floor to which a contact sensor of the hall door is connected , a volume sensor of the hall, a sound emitter, a siren, an electronic key reader, and the outputs of all control and switching units, through the receiver cable set , Connected with road access control unit (see. Russian PM №63832 cells E05V 47/00, 2007).

The disadvantages of the described device should include the likelihood of false events "Hacking" due to the malfunctioning of the volumetric sensor when the tenant leaves the hall and the lack of information about the apartment number, the tenant of which allowed a false alarm.

The objective of the proposed device is to eliminate these disadvantages.

The problem is solved due to the fact that in the well-known intercom and lock device of the entrance door of the building containing an electromagnetic lock, a call block, an electronic key, communication devices with remote control of the lock, and on each floor of the building a control and switching unit to which a contact sensor is connected hall doors, volumetric sensor of the hall room, sound emitter, siren, and an electronic key reader, apartment modules controlling the power supply are connected to the control and switching unit -being apartment doors with door contact sensor.

Figure 1 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 an electronic key code determination unit and a switching unit (not shown in the drawing), an electronic key 3 and intercoms with remote control of the lock (not shown shown). On each floor of the building, a control and switching unit 4 (1 ... n) is installed, where n is the floor number to which the contact sensor 5 of the hall door, the volume sensor 6 of the hall room, sound emitter 7, siren 8, electronic key reader 9, button are connected alarms 10, an indicator of the hall being guarded 11 and an apartment control module 12 with a contact sensor for the apartment door 13. An access control unit 14 with an information board connected to the outputs of all control and switching units 4 (1 ... n) through the receiver is installed in the building’s entrance cable network, interface module 15, which converts alarm messages from the driveway into the format necessary for the transmission of these messages over the air. The access control unit 14, the interface module 15 and the radio alarm transmission unit are powered by an uninterruptible power supply unit of 12 V, and the floor control and switching units 4 (1 ... n) and the call unit 2 - from an uninterruptible power supply unit of 24 V.

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 the integrity of the apartment cable networks with apartment modules 12, and using the access control unit 14, 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 code of the electronic key used to enter the staircase is transmitted through the digital line of the cable trunk network to the floor control and switching units 4 (1 ... n). The control and switching unit of the floor 4 (1 ... n), on which the apartment is located, to which the given electronic key is assigned, for the time specified by the algorithm of the system operation, disarms its hall.

The tenant must within a given time 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). In this case, 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 door of the hall, by 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 the floor by “breaking” the hall door, the floor block 4 (1 ... n) will record this event by the signals of the contact sensor 5 of the hall door and generate a warning alarm on the floor, which is sent to the sound emitter 7 and the receiver cable network to the access block 14. If within 30 seconds the warning sound signal on the floor is not turned off with the electronic key 3 attached to the electronic key reader 9, then the floor block 4 (1 ... n) will generate an alarm and it will transmit it to the floor siren 8. If within 1.5 minutes the siren signal on the floor is not turned off using the electronic key 3 attached to the electronic key reader 9, the drive unit 14 will transmit information about the alarm event to the information board and to the interface module 15 and further over the air to the central monitoring station.

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. If the tenant returns back (entrance to the hall from the outside) within the set time, then upon returning to the hall the floor unit 4 (1 ... n) considers this event completed and sets this floor to 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 is generated on the floor block for 30 seconds, which is transmitted to the sound emitter 7 and via the cable trunk network to the access block 14. The tenant, using his electronic key 3, within 30 seconds, it must turn off the warning signal on its floor by attaching its key to the reader 9. In this case, the alarm will not be transmitted to the floor siren 8 and to external circuits, and the hall of the floor will be armed.

If a tenant does not close the door when leaving the hall, 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. Also, a floor sound unit 4 (1 ... n) will generate a tonal sound signal of the open state of the door of the hall, which is transmitted to the sound emitter 7, warning residents of the floor about the need to close the door. If the tenant returns within a specified time back to the hall and closes the door, the exit from the hall by the 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 send it to the access block 14. From the entrance block 14, the signal open door hall will go to the information panel. If necessary, the signal for the open state of the hall door by the drive unit 14 is transmitted through the interface module 15 to the central console. 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, the floor unit 4 (1 ... n), for a period of 30 seconds, will generate a warning sound signal on the floor, which is sent to the sound emitter 7 and via the cable trunk network to the access block 14. The tenant, using his electronic key 3, within 30 seconds must disconnect on its floor a warning signal by attaching your key to the reader 9. In this case, the alarm will not be transmitted to the floor siren 8 and to external circuits, and the hall of the floor will be armed.

At each exit or entrance of a tenant from the apartment, the apartment control module 12 transmits to the floor control and switching unit 4 (1 ... n) a message about the operation of the contact sensor 13 of the door of the corresponding apartment. In this case, the floor control and switching unit 4 (1 ... n) generates a signal for disarming the hall, a duplicate signal of the room sensor 6 of the hall, and in the event of an alarm event, transmits to apartment block 14 the apartment number participating in the occurrence of this event.

The apartment control module 12 constantly monitors the closed state of the apartment door and transmits this information to the floor control and switching unit 4 (1 ... n). If the apartment door will be in an open state for more than the time specified by the algorithm of the system, the floor control and switching unit 4 (1 ... n) will send to the access block 14 a message about the open door, indicating the apartment number. If necessary, this message can be transmitted to the interface module 15 and then over the air to the central monitoring console.

In case of emergency, on the floor there is a button 10 "unconditional alarm" connected to the control and switching unit 4 (1 ... n), after clicking on which, the alarm signal is sent to the access control unit 14 and, if necessary, to the interface module 15 and further by radio to the central monitoring station.

The floor control and switching unit 4 (1 ... n) constantly monitors the integrity of the apartment lines and apartment control modules 12 and, if they are found to be malfunctioning, gives an open line signal to the access block 14, indicating the corresponding apartment number. If necessary, this message can be transmitted to the interface module 15 and then over the air to the central monitoring console.

The floor control and switching unit 4 (1 ... n) has the ability to turn on / off the video camera installed in the hall of the floor in case of an alarm.

The access control unit 14 constantly monitors the integrity of the trunk cable network lines and the floor control and switching units 4 (1 ... n) and, if a malfunction is detected, issues an alarm to the access unit 14, the information board, to the interface module 15 and then on radio channel to the central monitoring station.

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 apartment control module 12 is made on the microcontroller to the input of which the contact sensor of the apartment door 13 is connected, and to the output, through the switching elements, the apartment line connecting the apartment control module 12 with the floor control and switching unit 4 (1 ... n).

The access control unit 14 is made on a microcontroller with switching elements of the input and output circuits. The access control unit 14 provides the reception of information from floor units 4 (1 ... n), the processing of this data according to a predetermined algorithm, and the transfer of the necessary information to the information board that is part of the access unit and to the interface module 15. All data received by the access unit are stored in its non-volatile memory.

The interface module 15 is made on the microcontroller with switching elements of the output circuits and converts alarm messages received from the access control unit 14 into the operation signals of one of the 16 protected areas. Each zone has three output states, which allows transmitting three alarm messages for each zone. The number of interface modules 15, if necessary, can be increased by means of their parallel connection.

The application of the proposed device allows to prevent unauthorized access of unauthorized persons to the floor premises of the entrance, thereby ensuring the protection of apartments located in a guarded floor hall. At the same time, the floor hall is guarded around the clock, and no additional actions are required from the residents of the protected floor related to the setting and removal of apartments from the guard.
