Description

yCTTOKCTBO ALARM

The invention relates to the field of signaling and can be used for alarming signaling in case of unauthorized penetration of an attacker into a secure room / apartment /.

Currently, the country has a criminal situation due to a sharp increase in the number of apartment thefts. No more than 1-5 apartments are connected to the security system by law enforcement agencies in cities, and the alarm system is usually installed in those apartments where there is a telephone. Meanwhile, there are a lot of people who want to entrust their apartments to law enforcement agencies. There is no good and modern security system in the country. The existing security system is technically outdated. So, in one year, up to 400 thousand false calls occur. In this regard, social conditions require the development of a reliable and technologically intensive security system. This will require several tens of millions of rubles, which the country does not have. Therefore, a fundamentally new warning system is needed. At the same time, autonomous alarm systems, i.e. systems that localize individual apartments without outputting a signal to the control panel of law enforcement agencies.

The known system l,. containing reed switches located in the areas of windows and doors, a switching unit for switching on this theme siren / warning unit /, a searchlight and electronic unit, which includes a transfer transformer, a relay and an arrester element. The essence of this system is as follows. Before arming the room, the door opens and in the switching unit the mains power is connected to the system by the toggle switch. In this case, the capacitor is charged and the relay in the electrode unit does not turn on. After closing the door, the room is armed. In case of unauthorized opening of the door or breaking the window by an attacker, the capacitor discharges to the relay circuit, which is itself blocked. Searchlight and siren are activated by relay contacts. It is almost impossible to turn off the system quickly, as the switching unit is placed in the next room, the door to which is closed at IVIM GOSB 13/08

IOC and does not have a sensor. The presence of the hall provides good protection. Calculate the equipment from theft. The disadvantage of the ordered system is the lack of autonomous power supply, ToK. the attacker g "can pre-disconnect the mains voltage. In addition, the time delay, which is inherent in the circuit, obliges the slobbering staff to quickly turn off the system with the t mbler in the switching unit after opening the door, i.e. the system does not have circuits that would allow a service shutdown of the system,

Known system 2, structurally representing a housing with built-in siren, a battery and a line break detector. The lid of the case is equipped with contacts ensuring the inclusion of the siren during its unauthorized removal. Opening the hatch to change the battery is made using a special key. The specified system is a non-address autonomous alarm system and has the same drawback as the above system.

The known PsJ system, which is closest in technical essence to the proposed technical solution, contains a sensor including a reed switch and a permanent magnet, a synchronizer including a low-frequency generator, a tuning capacitor and a resistor, a capacitor, an accumulator, a switch, a warning unit / loudspeaker / and a power amplifier consisting of two transistors / with different conductors / resistors / and a resistor. The essence of the known device is as follows. When the room is armed, a door opens, a contact opens in the reed switch and the switch is set to a certain position. At the same time, a voltage is supplied from the battery to the microcircuit and the power amplifier. When the door is closed, the tab in the reed switch switches, the contact closes and the capacitor begins to charge. When the capacitor is charged, the alarm device switches to standby mode, IF an unauthorized opening of the door of the protected room occurs, the tab in the reed switch closes the contact and the capacitor starts to discharge. When the capacitor discharges, the low / sound / frequency generator starts. The audio signal is amplified and an acoustic alarm is generated by the loudspeaker, and the duration of the alarm is determined by the capacitor capacitance and acc; tU1ulyator, Analysis of the functional diagram of a known device shows that it has autonomous power, which allows you to keep

UNDER the security of the premises, regardless of the state of the electrical network, the voltage in which can be disconnected by an attacker .. The disadvantages of the device should also include unaddressing, because .. when the door is opened, an alarm always sounds, regardless of who opens it. The difference between the attacker and the owner is that the owner knows where the switch is lit up and the alarm time can be very long.

The essence of the invention lies in the fact that when entering a secured premises, it is necessary for a certain time. / For example 4-6 seconds / set by the entry timer on a dial field to dial a code combination identical to the code combination set in the device’s encoder, and when setting up an object the security on the dialed field is pressed by the Start button, after which, for a certain time, set by the exit timer / for example 6-8 seconds / the door of the protected room must be closed.

If these conditions are not met, an akinetic and visual warning is activated.

This goal is achieved by the fact that in the device containing the sensor, synchronizer, power amplifier and a notification unit with their high-level connections, a type-setting field, a memory unit, an input unit, a logical unit, an encoder, a trigger, an output timer, and two matching schemes are introduced mutual relations.

The output Ta% iepa 5 of the input is connected to the third input of the coincidence circuit 11, the output of which is connected to the input of the power amplifier 12, the output of which is connected to the first input of the notification unit 13

The principle of operation of the proposed alarm device is as follows.

Before installing the device on the object of protection, it is encoded. Coding consists in the fact that jumpers are installed on the printed circuit board / jumpers in those circuits that characterize the set of decimal digits on the typesetting field. For example, if CODE 1-4-7-9 is a code that disconnects the device from the security of the room, then in encoder 10, jumpers are installed in positions 1, 4, 7, S. In addition to that, before installing the device, a suitability test is performed autonomous power supply / batteries, elements like Mars, etc. /. To do this, on the composing field 1, the Control button is pressed and in the acoustic and visual warning unit 13, the emitting LED characterizes the set voltage level of the autonomous power source.

Suppose that the alarm device is ready for operation and the sensor is mounted on the door of the secure premises. When arming an object on the set-up field 1, the Start button is pressed. In this case, voltage is applied to the functional units of the device and the output timer S starts. At the same time, the door of the secured premises should: henna be closed no later than a second after turning on the device, because otherwise, in block 13, the siren is turned on. If the door is closed for f ij, then from the exit timer 9 to the logic unit 6, a zero potential is supplied, which is then fed to the coincidence circuit 11. The clock pulses from the synchronizer 2, arriving at the coincidence circuit 11, do not enable the power amplifier 12 and, accordingly, the siren in block 13. The door is closed and the room is guarded

Suppose that the door of a secure room is opened by an attacker. In case of an unauthorized opening of the door by an attacker at the output of the codeword comparison circuit 7, a unit potential is generated which is fed to the logic unit 6, in this case, unit potentials and clock pulses from the synchronizer are sent to the coincidence circuit 11 from the input timer 5 and from the logic unit 6 2 through the coincidence circuit 11 and the power amplifier 12, is supplied to the acoustic and visual warning unit 13. The duration of the alarm is determined by the capacity of the power source and the energy consumed by the speaker system.

Suppose that the door of a secured premises is opened, for example, by an office personnel who knows the code. In this case, after the door is opened, the official must, for a certain time / for example 4-6 seconds / dial a code combination, for example, 1, 4, 7, 9. At the output of the codeword comparison circuit 7, a zero potential is generated that switches the triggers to the zero state in the power-on block 8 and in the logic block 6. The input timer 5 is locked and the alarm signal is not emitted into the space o

Yaa fig.Z presents a diagram of the synchronizer k., Consisting of two elements IJ, a resistor, a capacitor and two counters. The NAND elements, a resistor and a capacitor are part of a given generator, and the values of the resistor and capacitor determine the initial generation frequency, and the number of bits in the counters is determined by the discrete sound of the siren in the notification unit 13.

In FIG. 4 is a diagram of a memory unit 4 that includes triggers and a resistor. The number of triggers is determined by the number of buttons for encoding on the pad. The resistor in the unit is used in the control circuit of the installation input of the triggers.

In FIG. 5 shows an input 5 containing an AND element, a counter and an NOT element. The essence of the operation of the input tasher 5 is that when the door is opened from logic block b, the unit And the unit potential is fed and the clock pulses from the synchronizer 2 in the form of logical 1 are accumulated in the counter. The total number of logical 1s accumulated in the counter is determined by the digit capacity of the counter, and, thereby, the specified delay time is determined from the moment the door is opened until the alarm is triggered. When a given number of logical 1s is accumulated at the output AND of the input timer 5, a unit potential is formed, i.e. permission is granted to match pattern 11. At the same time, through the element NOT to the input of the element And the zero potential is supplied. Thus, logical 1 no longer arrives at the synchronization input. The circuit of the TASHER S output is similar to the circuit of the input timer 5.

Figure 6 presents the diagram of the burn block 6, containing the element And and the counter. The essence of the operation of block 6 is that when leaving the protected premises, the owner is given a certain / limited / time, which is determined by the exit number 9. If the door turned out to be open for a time longer than the specified one, then a unit potential is supplied from the output of the timer S to the AND element. In addition, a unit potential is supplied from sensors 3. In this case, the trigger switches to the input of circuit 11

7 is a diagram of an encoder 7, which is a printed circuit board on which, according to a given code, jumpers are installed / fixed / in a certain position. From the block diagram of the encoder 7, it can be seen that the alarm signal is not emitted into space only when unit potentials are formed at the outputs 10 wi (| of the generator).

On Fig presents a multi-input circuit 10 matches, consisting of logical elements AND, the outputs of which are associated with a logical element OR. Logical 1 at the output of the coincidence circuit 10 is dormant only if there are logical 1 at its inputs,

On Fig presents a diagram of a power amplifier 12, consisting of a capacitor, a resistor and a transistor. The capacitor performs the functions of decoupling the constant component. The transistor is in key mode because in the initial state, it is closed by a resistor, and at the time of formation of the leading edge of the pulse due to the large signal level / logic level / transistor is set to a saturation state.

FIG. 10 is a diagram of a visual and acoustic warning unit 13 consisting of an LED with a limiting resistance and a loudspeaker.

The technical advantage of the proposed alarm device over the well-known technical solutions is the expansion of the field of application while increasing the security of the premises due to their personal coding, autonomous power supply and increased strength of the housing. In case of unauthorized opening of the door, the attacker cannot VK; turn off the siren and is forced to retire, because sound level and timbre are selected by the characteristics for alarming.
