Description

The invention relates to technical means of burglar alarms used to protect real estate (apartments, cottages, cottages, etc.).

The protected property may be a separate room containing material or other valuables, equipped with technical means of a security alarm, or a complex of premises dispersed within one or more buildings, united by a common territory.

The security structure of the property may include several security alarm loops, which are electrical circuits that connect the control panel with one or more security detectors. The receiving-control device is a technical tool for receiving notifications (via security alarm loops), converting them into notifications intended for direct human perception, and their subsequent transmission via communication channels (wired or wireless) of the notification transmission system to the central monitoring station ) and / or for issuing commands to enable sirens. In most alarm systems, sound sirens containing a siren and light sirens, which include various kinds of light indicators, are used ("Handbook of Engineering and Technical Workers and Electricians of Technical Equipment for Security and Fire Alarm". M., Ministry of Internal Affairs, 1997).

The technical facilities described above are the main components of alarm systems used in centralized security systems for various real estate entities of legal entities and individuals, carried out by private security units.

The disadvantage of centralized console security systems is the need for daily arming and disarming, especially inconvenient for users - individuals. It represents the inconvenience and the need to transfer to private security keys from the protected property. It should also be borne in mind that, as a rule, the responsibility for false calls of the quick reaction forces associated with the inattention of the user, for example, with an error when disarming, is assigned to the user.

These inconveniences prevent many potential clients, especially owners of expensive real estate, from concluding contracts for their centralized protection. In recent years, the number of such incredulous potential customers has increased markedly. As a result, the number of virtually unprotected expensive real estate has increased. Accordingly, the number of criminal attacks on them has increased. As noted in the newspaper "My house is my fortress", No. 1, September 2004, the boom of cottage construction that began among wealthy people was faced with a wave of organized crime. This sets the task of finding alternative ways to build alarm systems. One of such ways is to use the possibility of psychological impact on the attacker.

The fact is that at the time the crime was committed, the attacker, like any predator, is extremely aggravated by all his feelings. It is important for attackers to know that they are alone in the room and their actions are not controlled by anyone. Having penetrated into the guarded room, the attacker tries, first of all, to turn off the security alarm, for example, by de-energizing the control and reception device. Any sound or light alarms the attacker, and an increased and growing level of sound and light alarm over time can lead him to a state of panic and a readiness to flee.

Robbery statistics show that in (40-65)% of cases (depending on the region), attackers run away if at least some siren sounds in the guarded room and its sounds can be heard outside. Unfortunately, the widespread use of sirens has created more resistant to this type of alarm signaling of intruders. First of all, they seek to stop this noise, providing themselves with conditions that are comfortable for robbery. As a rule, especially in small rooms, finding a siren is not difficult. It is also incapacitating from failure. After neutralizing the siren, the attackers suspend their activities for a while and wait. They listen to everything that happens around. Imagine that some time after the first siren is turned off, the second siren is triggered, and with a higher volume than the first. Further, a third siren may work, etc. At the same time, the sound pressure level gradually rises. This scares not only the mindless violators (homeless people, drug addicts, etc.), but also experienced professionals. In such an environment, any surprise can lead to a nervous breakdown and flight of the attacker from the crime scene.

The proposed technical solution is aimed at using this psychological factor.

The prototype of the invention is the well-known fire alarm system of the Struna family, which includes the Struna-3M radio alarm transmission system with the Struna-801 receiving and control device PPKOP0114-8-1 / 1 GKUN.425513.001, commercially available applicant company (Passport ГКУН.425513.001 ПС, Moscow, "Altonika", 2004). Information about the specified equipment is also given on the website of the Scientific Research Institute "Security" (www.nicohrana.ru).

The security and fire alarm equipment of the Struna family is designed to protect real estate objects and contains sound annunciators distributed throughout the protected property, each of which contains a siren, and light annunciators, each of which contains a light indicator, such as a strobe light, as well as cables burglar alarm, to which sound and light sirens are connected, a control and reception device, connected - directly - with a remote control panel and - by radio iru - with a label carried by the user of the protected real estate object (for remote identification of the user). The receiving-control device comprises a control device configured to exchange data with the control panel, a reader connected to the control device and configured to interact with the tag over the air, a notification transmission unit configured to receive notifications from the control device and transmit them over the wire and / or via wireless communication channels to the monitoring station, and a power circuit consisting of a stabilized power source connected in series, configured to li ne via circuit breaker to the mains of 220 V, 50 Hz, backup battery and switch connected to the input of the power control unit, which is associated with the security alarm loops.

In the framework of the present invention are not considered schemes for constructing devices for receiving and processing information in the monitoring station, since this does not apply directly to the subject of the invention. Beyond the scope of the present invention, all that relates to fire alarms is also deduced.

As in other regular security alarm systems designed for centralized protection of real estate, the security and fire alarm systems of the Struna family do not have anti-intruder mechanisms in place to prevent or at least reduce the risk of losses from their actions on the property’s territory (before the arrival of the rapid reaction forces). This is a disadvantage of this equipment.

The present invention seeks to remedy this drawback.

The subject of the invention is a security alarm system for real estate, containing sound annunciators distributed throughout the protected property, each of which is made with a siren, light annunciators, each of which is made with a light indicator, as well as security alarm loops, with which security detectors are connected and control and reception device, connected by a power input using a knife switch to the mains, connected directly to the control panel and via radio to find by the user’s label, and configured to transmit notifications to the monitoring station, in this case, a microprocessor information processing and command synthesis unit, a common power bus and one or more voice annunciators, each of which contains a voice driver and loudspeaker, and each sound, light and voice siren has autonomous power supply and control units, the outputs of which are connected, respectively, to the siren, the light indicator and the shaper of voice messages, and the inputs to the common power bus, which is also connected to the output of the microprocessor unit for information processing and command synthesis, while the signal input and power input of the microprocessor unit for information processing and command synthesis are connected, respectively, to the signal output and to the power output of the control panel.

Particular salient features of the present invention are as follows.

The control and reception device includes a control device configured to receive notifications on security alarm loops, transmit power voltage to security detectors on the indicated security alarm loops, and also with the possibility of exchanging data with the control panel, and equipped with outputs, one of which is a power output the control and reception device, and the other, by the signal output of the control and control device, a reader connected to the control device and configured to interact I’m on the air with a label, a notification transmission unit whose input is connected to the command output of the control device, and the output is the output of the control and reception device, designed to transmit notifications via wired or wireless communication channels to the monitoring station, as well as a power circuit that includes in series connected stabilized power source, the input of which is the power input of the control panel, the first charging circuit, the second output of which is connected to the power input of the control device, and the first the battery is connected to the input of the backup power management device.

There are two options for building a microprocessor unit for information processing and command synthesis.

The first is a simplified version of constructing a microprocessor unit for processing information and synthesizing commands, which contains a series-connected first matching unit, the signal input and power input of which are, respectively, the signal input and power input of the microprocessor unit for processing information and command synthesis, and a microprocessor whose power input is connected to the power input of the first matching unit, and the output is the output of the microprocessor unit for information processing and command synthesis connected to a common power bus.

The second - more complex option - constructing a microprocessor unit for processing information and synthesizing commands contains a first matching unit in series, the signal input and power input of which are, respectively, the signal input and power input of the microprocessor unit for processing information and command synthesis, and a microprocessor whose power input is connected to the power input of the first matching unit, as well as a second charging circuit connected in series, the input of which is connected to the power input of the first eye coordination and a second battery connected to the inputs of the backup power supply, respectively, the first matching unit and a microprocessor, the output of which is connected to a common power bus output microprocessor information processing unit and synthesis commands.

Each of the autonomous power supply and control units contains a second matching unit, a decoder and a controlled relay, as well as a third charging circuit connected in series to the signal input of the second matching unit and is the input of this autonomous power and control unit, and a third battery, the output of which is connected to the contact group of the controlled relay and the power inputs of the second matching unit and decoder, while the output of the controlled relay is configured to li ne a siren, a light or a builder to voice messages.

The invention is illustrated using the drawings shown in figures 1-8.

The considered alarm system for real estate (Fig. 1) contains distributed over the territory of the protected real estate:

- sound annunciators 10, each of which contains a siren 12, to the input of which is connected an independent power supply and control unit 25;

- light annunciators 11, each of which contains a light indicator 13, to the input of which is connected an independent power supply and control unit 25;

- voice sirens 14, each of which contains a series-connected unit 25 of autonomous power and control, driver 31 voice messages and loudspeaker 15.

The security detectors 5 and the control and reception device 1 are connected to the security alarm loops 4, with which the control panel 3 is connected. The security alarm loops 4 are designed to transmit to the device 1 alarm and control notifications from security detectors 5 and to supply power to security detectors 5 from the device 1 reception and control. Label 7 located at the user is connected with the device 1 reception and control by radio.

The receiving-control device 1 (Fig. 2) contains a control device 8, configured to connect security alarms 4 and with the possibility of two-way interaction with the control panel 3, a reader 6, connected directly to the control device 8 and - by radio - with a label 7, as well as a notification transmission unit 9, connected to one of the outputs of the control device 8, and configured to transmit notifications to the monitoring station via wired and / or wireless communication channels. The control unit 1 also includes a power circuit, consisting of a stabilized power source 18 connected in series, made with the possibility of connecting, using a knife switch 2, to a 220 V, 50 Hz power supply, the first charging circuit 19, the second output of which is connected to the input power supply of the control device 8, and the first battery 20, the output of which is connected to the backup power input of the control device 8. In this case, the power output and the signal output of the control device 8 are, respectively, the power output and the signal output of the control and reception device 1.

In addition, the considered security alarm system for real estate contains a common power bus 16, to which the inputs of all 25 power supply and control units 25 (included in the sound 10, light 11 and voice 14 sirens) are connected, as well as the output of the microprocessor information processing unit 17 and command synthesis.

The microprocessor unit 17 for information processing and command synthesis can be performed in two construction options (figure 3 and figure 4).

The first is a simplified version (figure 3) - contains in series the first matching unit 21, the signal input of which is the signal input of the microprocessor unit 17 for processing information and command synthesis, and the microprocessor 22, the output of which is the output of the microprocessor unit 17 connected to a common power bus 16 information processing and command synthesis.

In this case, the power inputs of the first matching unit 21 and the microprocessor 22 connected to each other are the power input of the microprocessor unit 17 for information processing and command synthesis.

The indicated construction option (Fig. 3) of the microprocessor unit 17 for processing information and command synthesis is intended for use in cheaper security systems than the second option, which has its own backup power source.

In the second construction option (figure 4), the microprocessor unit 17 for processing information and synthesizing commands contains:

- serially connected first matching unit 21, the signal input and power input of which are, respectively, the signal input and power input of microprocessor unit 17 for processing information and command synthesis, and microprocessor 22, whose power input is connected to the power input of the first matching unit 21, and the output is the output of the microprocessor unit 17 for information processing and command synthesis, connected to a common power bus 16;

- connected in series to the second charging circuit 24, the input of which is connected to the power input of the first matching unit 21, and the second battery 23.

In this case, the first matching unit 21 and the microprocessor 22 are made with backup power inputs to which the second battery 23 is connected.

The availability of backup power allows the microprocessor unit 17 for information processing and synthesis of commands to maintain operability even when the power supply to it is stopped from the receiving-control device 1.

Each sound siren 10 (Fig. 5) consists of a series-connected unit 25 of autonomous power and control, the input of which is the input of this sound siren 10, and a siren 12.

Each light siren 11 (Fig.6) consists of series-connected unit 25 of autonomous power and control, the input of which is the input of this light siren 11, and a light indicator 13.

Each voice siren 14 (Fig. 7) consists of a series-connected unit 25 of autonomous power and control, the input of which is the input of this voice siren 14, driver 31 voice messages and loudspeaker 15.

Each of the aforementioned autonomous power supply and control units 25 (Fig. 8) contains a second matching unit 28 in series, the signal input of which is the input of this autonomous power supply and control unit 25 for connecting to a common power bus 16, a decoder 29 and a controlled relay 30 , the output of which is the output of this block 25 of autonomous power and control. The independent power supply and control unit 25 also includes a third charging circuit 26 connected in series, the input of which is connected to the signal input of the second matching unit 28, and a third battery 27, to which the contact group of the controlled relay 30 and the power inputs of the second matching unit 28 and decoder are connected 29. At the same time, the output of the controlled relay 30 is configured to connect, respectively, to the siren 12, to the light indicator 13 or to the shaper 31 of voice messages.

All of the above nodes, functional blocks and their components, with the exception of the common power bus 16, microprocessor unit 17 for processing information and synthesizing commands and voice annunciators 14 are used in the receiver-control device Struna-801 PPKOP0114-8- commercially available 1/1 GKUN.425513.001 (Passport GKUN.425513.001 PS, Moscow, "Altonika", 2004).

A common power bus 16 and a universal control circuit (Fig. 8) consisting of a second matching block 28, a decoder 29 and a controlled relay 30 connected in series implement the “HOOK-UP” technology, a method for controlling alarm system nodes using a standard bus wiring. The use of this method for the protection of automobiles was proposed by the applicant company in 1996 (patent RU No. 2090395, 60 R 25/00). This technical solution was widely used and was implemented in the family of security and anti-theft systems (catalog "Automotive Security Systems". M., "Altonika", 2004, p.4-7), commercially available by the applicant company under the trademarks BLACK BUG® (certificate No. 158593) and REEF® (certificate No. 182300). The combination of the control signal transmission channel with the common power bus 16 made it possible to simplify the installation of the alarm system nodes (fewer wires are required), and most importantly, to increase the secrecy of their installation in cars. The same positive result is achieved in the considered alarm system for real estate.

An analogue of the driver of 31 voice messages is used in the REEF HF-1000 car speakerphone set commercially available by the applicant company (certificate of conformity No. POSS RU.ME30.B.01281). In addition, the specified driver of 31 voice messages is an integral part of a number of automotive security systems previously patented by the applicant company (for example, RU No. 2211159, 60 R 27/00, RU No. 2214933, 60 R 25/00, 60 R 27 / 00).

The microprocessor unit 17 for information processing and command synthesis is made using a conventional microprocessor 22, commercially available from the industry.

As for such units (or their components), such as circuit breaker 2, first 20, second 23 and third 27 batteries, a stabilized power supply 18, first 19, second 24 and third 26 charging circuits, these are ordinary electrical devices widely used at home.

Thus, all the functional units and blocks used in the proposed system are well known, are commercially available and are available for commercial use. Therefore, the possibility of practical implementation of the proposed technical solution is not in doubt.

The considered alarm system for real estate works as follows (based on the logic of the reception and control device "String-801" PPKOP0114-8-1 / 1 GKUN.425513.001).

The connection of the control panel 1 to the 220 V, 50 Hz power supply is carried out using the switch 2 and is indicated on the control panel 3.

The supply voltage is supplied through the security alarm loops 4 from the control and reception device 1 to the security detectors 5.

The main operating modes of the system are: DISARMED, ALARMED and ALARM.

The system switches to the ALARM mode from the TAKE ALARM mode when one of the security detectors 5 is triggered and the receiving and control device 1 receives a corresponding notification about the operation of this security detector 5. In addition, the transition to the ALARM mode is carried out if the corresponding alarm loopback 4 is violated (for example , at its break).

The switching of operating modes (from the DISARMED ARMED mode to the ARMED ARMED mode, or from the ARMED ARMED mode to the DISARMED ARMED mode, or from the ALARM mode to the DISARMED ARMED mode) is carried out by the user using the control panel 3. Any of the indicated modes switching operation is possible only if, in the range of the antenna of the reader 6, which is part of the control and reception device 1 (Figs. 1 and 2), there is a mark 7 previously registered in the memory of the control device 8 of the control and reception device 1. The radius of the range of the reader antenna 6 is approximately one meter, which allows the user to use the tag 7 without removing it from the pocket.

If the user needs to transfer the system from the DISARMED SECURITY mode to the ARMED SECURITY mode, then he must first make sure that all users except the user have left the protected room. Then this user should, being in the range of the reader antenna 6, issue, with the help of the control panel 3, a command to switch to the ARMED ARMED mode. The control device 8 detects that the reader 6 has detected a tag 7 registered in the memory of the control device 8, and a command has been received from the control panel 3 to switch to the ARMED ARMED mode. After that, the control device 8 waits for a signal from the security detector 5 installed on the entrance door of the secure room. This signal corresponds to closing the front door when the user leaves the guarded room. After the user leaves the guarded room and closes the front door, the control and reception device 1 delays the transition to the TAKE-IN-GUARD mode for a certain period of time necessary for transient processes in those security detectors 5 that contain volume sensors.

The duration of the specified period of time is set programmatically. For example, for the Instrument of reception and control "String-801" PPKOP0114-8-1 / 1 GKUN.425513.001 the typical value of this time period is 45 s.

At the end of the specified period of time, the device 1, the control panel puts the system in the RECOVERY SYSTEM mode. At the same time, according to the appropriate command from the control device 8, the notification transmission unit 9 sends a TAKE message to the monitoring station.

The transition of the system from the ARMED SECURITY mode to the DISARMED mode starts after the user opens the entrance door and enters the secure room. The opening of the entrance door is fixed by the corresponding security detector 5. The signal from this security detector 5 is sent to the control device 8 of the control panel 1 of the control panel via the corresponding security alarm loop 4. According to this signal, the control device 8 captures the beginning of the time interval, which is called the “entry delay”, and issues to the reader 6 a command to search for the tag 7 registered in the memory of the control device 8. The entry delay time is set when programming the control device 8. The typical “entry delay” value is 30 s.

During the “entry delay” time, a user with a tag 7 registered in the memory of the control device 8 must enter the range of the reader 6 antenna. The code of the tag 7 is transmitted to the control device 8 through the reader 6. The control device 8 identifies the tag 7 as one of the memory 8 of the control device. At the command of the control device 8, the system enters the DISARMED state. At the same time, according to the appropriate command from the control device 8, the notification unit 9 sends the message DISCONNECTED to the monitoring station.

If the tag 7, registered in the memory of the control device 8, is not detected, then at the end of the "entry delay" time, the system goes into ALARM mode.

When any security detector 5 is triggered, except for the security detector 5 of the front door, and also if any of the security alarm loops 4 is violated, the system switches to the ALARM mode instantly.

When entering the ALARM mode by the appropriate command of the control device 8, the notification unit 9 sends an ALARM message to the monitoring station (with a possible addition to the nature of the alarm).

As in the prototype system, the ALARM mode is accompanied by the inclusion of sound 10 and light 11 sirens, in which sirens 12 and light indicators 13, respectively, are triggered.

In the claimed system, in addition to sound 10 and light 11 sirens, in the ALARM mode one or several voice sirens 14 can be turned on. Each voice siren 14 allows you to synthesize a specific voice message and sound it using a loudspeaker 15. This creates an attacker who illegally penetrated guarded property (for example, in the user's apartment), the illusion that this property is under operational surveillance.

The logic of operation in the ALARM mode (on / off order, duration and volume of the sound of sirens 12, brightness and / or flashing of the light indicators 13, etc.) is set programmatically using special software settings. These program settings are implemented by supplying high-frequency frequency-modulated signals via a common power bus 16 from a microprocessor unit 17 for processing information and synthesizing commands to the inputs of sound 10, light 11, and voice 14 sirens, respectively. In addition, in each sound 10, light 11 and voice siren 14, so-called fixed-mode programs are introduced, which are activated when a malfunction of the common power bus 16 is detected.

The power supply of the considered alarm system for real estate is carried out using the power circuit, consisting of in series:

- a stabilized power source 18, the input of which, through the switch 2, is connected to a 220 V, 50 Hz power supply;

- the first charging circuit 19, the second output of which is connected to the power input of the control device 8;

- the first battery 20 connected to the backup power input of the control device 8.

When the circuit breaker 2 is open (or if the voltage of 220 V in the mains disappears for some reason), the stabilized power source 18 is de-energized, the voltage is not supplied to the power input of the control device 8. At this point, the control device 8 automatically switches to power from a backup source - the first battery 20, which by this time should be charged using the first charging circuit 19. When switching to power from a backup source, the control device 8 transfers a control action to the control panel 3, according to which the control panel 3 turns off the indication of the connection of the device 1 of the control panel to the mains 220 V, 50 Hz.

After restoring power from the mains 220 V, 50 Hz, the control and reception device 1 returns to the mode in which it was before the power was turned off. The control device 8 again generates a control action, according to which on the control panel 3 the fact of connecting the receiving and control device 1 to the 220 V, 50 Hz power supply is indicated. The facts of power failure through the electric network 220 V, 50 Hz are stored in the memory of the control device 8 and then, using the notification transmission unit 9, the corresponding notifications can be transmitted to the monitoring station.

A distinctive feature of the proposed security alarm system for real estate, in comparison with the prototype system, is the ability to control in the ALARM mode sound 10, light 11 and voice 14 sirens with the help of commands sent in the form of frequency-modulated signals via a common microprocessor power bus 16 block 17 information processing and synthesis of commands. Sequences of these commands (software settings) are previously (in the DISARMED mode) written to the non-volatile memory of the microprocessor unit 17 for processing information and command synthesis from the control device 8 of the control and reception device 1 after being removed from the ARMED mode using the so-called master -the tags they were recorded in the memory of this control device 8.

As in the prototype system (Instrument reception and control "String-801"), to change the software settings, you must first change the contents of the master label using a special programmer. Then, the changed parameters must be rewritten from the master tag in the memory of the control device 8.

To carry out this census, the system is transferred to the DISARMED mode, and then a master tag is installed near the reader antenna 6. Using the control panel 3, the control unit 8 sets the mode for overwriting program settings from the master tag into the memory of the control device 8. The dubbing process is controlled using the control panel 3. At the end of the dubbing process of the software settings, the system automatically returns to the DISARMED state. The software settings from the control device 8 are rewritten into the non-volatile memory of the microprocessor unit 17 for processing information and command synthesis is carried out automatically after the system is put into the ARMED PROTECT mode.

In this case, from the control device 8 of the device 1, the reception and control program settings are supplied to the signal input of the microprocessor unit 17 for processing information and synthesis of commands, through the first block 21 matching are fed to the microprocessor 22 of the microprocessor unit 17 for processing information and synthesis of commands and are recorded in non-volatile memory of the microprocessor 22 .

Figures 3 and 4 show two embodiments of a microprocessor unit 17 for processing information and command synthesis, differing in the power supply scheme for the first matching unit 21 and for the microprocessor 22.

In the embodiment shown in FIG. 3, the supply voltage from the power output of the control and reception device 1 is supplied to the power input of the microprocessor unit 17 for processing information and command synthesis, and inside this unit is supplied to the power inputs, respectively, of the first matching unit 21 and the microprocessor 22. Power backup (in case of deliberate breaking by criminals of the connections of the microprocessor unit 17 for processing information and command synthesis with the receiving-control device 1) is not provided, which, as noted above, is n a drawer of the indicated option.

In the embodiment shown in Fig. 4, a backup power source is used - a second battery 23 connected to the power input of the microprocessor unit 17 for processing information and synthesizing commands using the second charging circuit 24. In the ARMED mode, the voltage from the power output of the device 1 is received control enters the power input of the microprocessor unit 17 information processing and synthesis of commands. Inside this unit, the supply voltage is supplied to the power input of the first matching unit 21, to the input of the second charging circuit 24 (which charges the second battery 23) and to the power input of the microprocessor 22. The backup power inputs of the first matching unit 21 and the microprocessor 22 are de-energized. In the event of a power failure at the power input of the microprocessor unit 17 for processing information and command synthesis, the first matching unit 21 and the microprocessor 22 switch to power from a backup source - the second battery 23. Moreover, the power supply itself at the power input of the microprocessor unit 17 for information processing and command synthesis that occurred in the ARMED ALARM mode is considered by this block as a command to enter the ALARM mode.

The supply voltage of the sound 10, light 11 and voice 14 sirens and high-frequency signals carrying control commands for these sirens in the ALARM mode are supplied via a common power bus 16 from the output of the microprocessor 22 to the inputs of the autonomous power and control units 25 (Fig. 8) installed in each sound 10, light 11 and voice 14 siren. This voltage feeds the third charging circuit 26, the output of which is connected to a backup power source to the third battery 27. The third charging circuit 26 controls the charge voltage of the third battery 27, for example, a rechargeable battery. As a result, the third battery 27 is charged to the rated voltage.

From the third battery 27, the supply voltage is supplied to the corresponding power inputs of the second matching unit 28 and decoder 29, as well as to the contact group of the controlled relay 30.

As soon as the voltage at the power inputs of the second matching unit 28 and decoder 29 reaches a predetermined threshold level, the second matching unit 28 and decoder 29 are turned on. Turning off the receiving-control device 1 or disconnecting it from the microprocessor unit 17 for processing information and command synthesis is a start command perform software settings of the ALARM mode recorded in the memory of the microprocessor 22 of the microprocessor unit 17 for processing information and synthesizing commands. At the signal input of the second matching unit 28, from the memory of the microprocessor 22 via a common power bus 16, sequences of commands pre-rewritten from the control device 8 begin to arrive in the form of frequency-modulated signals carrying predetermined program settings. The second matching unit 28 converts the indicated frequency-modulated signals into binary symbol sequences that are input to decoder 29. Decoder 29 extracts command codes from the binary symbol sequence and feeds them to the input of the winding of the controlled relay 30.

According to these commands, at certain times, the contacts of the controlled relay 30 are closed or opened. As a result, the voltage set by the third battery 27 appears or turns off at the output of the controlled relay 30. Accordingly, sirens 12, light indicators 13 or voice shapers 31 turn on or off. messages. The time intervals during which this managed relay 30 is in the on or off state, determined by its software settings.

Consider the behaviors of the security alarm system under consideration, depending on the actions of attackers seeking to penetrate the guarded real estate.

Suppose that the robbers picked up the keys or cracked the front door. This led to the operation of the security detector 5 of the front door, but, as noted above, for a certain period of time corresponding to the specified "entry delay", the system does not go into ALARM mode.

During this time, attackers can try various options for affecting the alarm system in order to neutralize or disable it.

Option 1

Attackers, by opening circuit breaker 2, or by damaging the electric wires supplying external power supply (220 V, 50 Hz), turn off the power of the control panel 1 from the 220 V, 50 Hz power supply. Like the prototype system, the system in question will automatically switch to power from the backup source - from the first battery 20. The voltage will be supplied to the backup power input of the control device 8. After the “entry delay” time has elapsed, the system will go into the ALARM mode, that is, the sound 10, light 11 and voice 14 sirens will start to turn on / off sequentially, and alarm notifications will be transmitted to the monitoring station through the notification transmission unit 9. This, of course, does not suit intruders.

Option 2

The attackers knew in advance or immediately discovered the installation location of the device 1 reception and control. Then, after they penetrate the protected real estate object, they can damage the communications coming from the control and reception device 1 to the microprocessor unit 17 for processing information and command synthesis, and / or disable the control and reception device 1 itself. If this had been done with the prototype system, then it would have been completely disabled and the attackers would be able to continue their actions without hindrance without risking being detected.

In the system under consideration, this will not happen, since sound 10, light 11 and voice 14 sirens connected by a common power bus 16 will switch to autonomous power supply from a backup source installed in each of them.

If the microprocessor unit 17 for processing information and synthesizing commands is made according to the simplified scheme shown in Fig. 3, that is, does not contain a backup power source, then the ability to flexibly control the sound 10, light 11 and voice 14 sirens using software settings will be lost stored in non-volatile memory of microprocessor 22. However, sound 10, light 11 and voice 14 sirens will work without control in some fixed mode of operation, the initial moment of switching on of which occurs when disconnecting the voltage on the common bus 16 power.

The autonomous power supply and control unit 25, which is part of each sound 10, light 11, and voice 14 sirens, responds to a voltage failure on a common power bus 16 as a command to turn it on of its actuator, for example, a siren 12 installed in a sound siren 10. V in accordance with this command, the voltage from the third battery 27 will, with certain interruptions determined by the fixed program of operation of the decoder 29, come from the output of the controlled relay 30 (that is, with its contact group) to the power input of the siren 12, which will begin to sound audible alarms in a fixed mode of operation.

The sound signals generated by the sound siren 10 are terminated in one of the following cases:

- when the voltage drops on the third battery 27 (due to its discharge) below a certain threshold level;

- when attackers detect this sound siren 10 and disable it;

- after the time interval specified by the program fixed mode of operation.

In exactly the same way, for all sound 10, light 11, and voice 14 sirens, the fixed mode of operation will continue until either their autonomous power sources are exhausted, or until they are completely destroyed by intruders, or until the end of the fixed mode program.

If the microprocessor unit 17 for processing information and synthesizing commands is made according to the scheme shown in Fig. 4, that is, it contains a backup power source, then it is possible to control the sound 10, light 11 and voice 14 sirens using the program settings for the ALARM mode stored in the non-volatile memory of the microprocessor 22, will not be lost.

The duration of the supply of each signal will in this case be determined by the software installation recorded in the non-volatile memory of the microprocessor 22.

Attackers who entered the guarded real estate object may find the installation location of the activated sound siren 10, after which they will neutralize it even before it has time to work out the resource of its backup power source - the third battery 27.

However, this will require certain physical efforts and time from them, since the triggered sound annunciator 10 can be installed in an inaccessible place, for example, under the roof of a house. But even if it is possible to disable the aforementioned sound siren 10, such actions will not lead to the desired result, because after a certain programmed interval of the “siren delay”, another sound siren 10 will work, installed, for example, in the basement of a guarded house. Accordingly, the winding of the controlled relay 30 will receive a command to turn on another siren 12. In accordance with its software installation, this siren 12 will begin to give audible alarms of an even higher volume.

Likewise, the light 11 and voice 14 sirens are turned on and off, also dispersed throughout the territory of the protected property and designed for additional psychological impact on the attackers.

The search for each new triggered sound 10, light 11 or voice 14 siren requires time and physical effort from the attackers, and most importantly, psychologically affects them, causing self-doubt and a desire to escape from the crime scene.

Fundamentally, nothing will change if the attackers damage the common power bus 16 or destroy the microprocessor unit 17 for processing information and command synthesis. In this case, the ability to flexibly control the sound 10, light 11 and voice 14 sirens with the help of the ALARM mode software settings stored in the non-volatile memory of the microprocessor 22 will be lost. That is, as with the execution of the microprocessor information processing and synthesis unit 17 according to the scheme of FIG. .3, after disconnecting the voltage on the common power bus 16, the sound 10, light 11, and voice 14 sirens will switch to a fixed mode of operation.

The bright flashing light of the light indicators 13 and the set of corresponding voice messages such as “Penetration notification sent”, “Order No. XXX left”, etc., stored in the shaper 31 voice messages are capable of exerting a demoralizing effect on the attackers and force them to abandon the original intentions.

This achieves a psychological effect, the idea of using which is the basis of this invention - to scare away intruders, forcing them to panic escape from a guarded real estate object, without having time to cause significant material damage to property and material values. Therefore, ceteris paribus, the considered alarm system is more effective than the prototype system.

Thus, the combination of new and common with the prototype system essential features allows us to solve the stated problem: to create an alarm system to protect real estate, which can prevent or at least significantly reduce material damage from the presence of cybercriminals at a guarded real estate.

The provided technical result consists in the implementation of an intelligent control mode for a set of sound, light and voice annunciators, which provides a psychological effect on attackers.
