Description

 The invention relates to signaling with vibration sensors.

A device for alarming, including a sensor, amplifier, first and second delay units, a rectifier, a Schmidt trigger, a waiting multivibrator, an indication unit and an alarm unit [1]
The disadvantage of this device is its lack of efficiency in the conditions of careful attempts to remove the external elements of protected objects against the background of random vibration disturbances from passing heavy equipment, when the proportion of low-frequency components in the background vibration environment is high, which often makes it necessary to reduce sensitivity to the threshold when careful removal attempts go unnoticed .

Also known is an alarm system for protection against intrusion, consisting of a series-connected sensor, input amplifiers, filter, detector, summing buffer, forming a block of the voltage reference level, resistor divider, normalizing comparator, timer, first AND-NOT element, delay comparator, second element NAND, output buffer element, installation block and operational diode [2]
The disadvantage of this device is the lower sensitivity than systems with a rigidly set threshold level of sensitivity, as well as the ability to mask cautious attempts to remove the external elements of protected objects under artificial vibration backgrounds, which limits the scope.

 The objective of the invention is to increase the sensitivity and expand the functionality of the system through the use of parallel branches of the analysis both by exceeding a hard-set threshold and by integrating the vibration environment.

 When you turn on the power before leaving the security zone, the system starts with the fact that the initial installation unit 6 issues a preset signal to the sixth input of the forming unit 11, which is valid for a time that is sufficient for a sure exit from the security zone. The forming unit 11 transmits this signal simultaneously to its fourth and sixth outputs, thus blocking the executive unit 4 and the blocks for extracting repeated disturbances and a sequence of short-term disturbances 7 and 8.

 Vibration disturbances that occur when trying to break into or remove the external elements of protected objects are converted by the sensor 1 (Fig. 1) into an electrical signal, which is amplified by the amplifier 2 and gets to the input of the detector 3. Here, the one passing through the first isolation capacitor 13 (Fig. 2) of the signal, the first diode 15 cuts off the negative component and through the average output of the first bit tuning resistor 14, the rectified signal is fed to the input of the pulse perturbation isolation unit with pumping of the threshold 9 and to the first forming the second input unit 11 having a two channel comparator thresholds are set by the user is released. The triggering signals of these channels comparing the input signal arriving at the first input of the forming unit 11 with predetermined threshold voltages are supplied separately to the first, second outputs of the forming unit 11 and get to the first inputs of the block for extracting repeated disturbances 7 and the block for isolating the sequence of short-term disturbances 8, which can work in parallel, analyzing the response signals of the comparator channels of the forming unit 11 for the duration, as well as the duty cycle and repetition rate, moreover, in parallel with them, the pulse disturbance separation unit with pumping of the threshold of operation can also work 9. The allocation units 7-9 can be included or excluded by the user in the analysis of the nature of external disturbances in accordance with the conditions of use of this alarm system. The operation signals of any of the extraction blocks 7-9 included in the analysis highway, respectively, arriving at the second, fourth inputs of the forming block 11, lead to its operation. The forming unit 11, at the request of the user, can operate in the instant response mode to an external disturbance, or in the delay mode. The user can also set the mode of direct response to an external disturbance with the switching off of the operation signals of the extraction units 7-9 or in parallel with them with the screening signal only on the basis of exceeding the threshold. In the case of the use of the probable absence timer 12, which is turned on before leaving with the setting of the absence time, with the simultaneous transfer of the forming unit 11 to the operation mode with a delay for a specified absence time, in case of any penetration attempts, after the characteristic signal is allocated, the executive unit 4 will immediately trigger . After a predetermined absence time, the forming unit 11 switches to the delayed response mode. From the third output of the forming unit 11, the time-normalized response signal generated in the forming unit 11 after processing the external disturbance signal, in accordance with the selection character set by the user, is output to the first input of the executive unit 4. At the fourth input of the forming unit 11 from the first output of the pulse perturbation separation unit 9, a time-irregular, increased noise immunity response signal is provided with a sharp nature of external perturbations with a duration of several seconds. With the appearance on the third output of the forming block 11, a trigger signal that triggers the actuator block 4, as well as when the trigger signal of the block of allocation of impulse disturbances 9 comes from its first output, the total collection signal with a margin in time overlapping the trigger signal of the generating block 11 and arriving at the second inputs of the allocation blocks 7 and 8, blocking them from power interference arising from the operation of the Executive unit 4. On-off signal system ization produced by disconnecting the block 10, the switching power supplied by an external DC bus voltage. Temporary blocking of the elements of the executive unit 4 and the forming unit 11 is carried out by means of a contact recognition device that generates a blocking signal at the first output of the shutdown unit 10, which arrives at the seventh input of the forming unit 11, which in turn transports it to the fourth and sixth outputs. Thus, a temporary blocking of the operations for the time of entry into the protected area and a power outage are made. The signal for extracting a short-term external disturbance against the background of external noise arriving at the third input of the extraction unit 8 from the second output of the extraction unit 9 imitates when the consumer sets the appropriate mode for the operation of the extraction unit 8 by a sequence of signals from the second output of the extraction unit 9 during the control time period from the initial short-term external disturbance. The fifth output of the forming unit 11 from its second input, when the user sets the operation mode with open circuit of external devices, the response signal of the repeated disturbance isolation unit 7 is transmitted. The group of parallel input chains used in this alarm system from separate sensors and adjustable resistor dividers 5 serves to track several security objects with different levels of probable external disturbances through one control channel, to the input of which parallel inputs are connected one chain with sensors 1 scattered around the protected area. In the Executive unit 4 (figure 3), the first toggle switch 16 sets the first or fourth excitation input for a sound generator with a controlled start 21 and the first and second inertia-free timers 22 and 23. When the second toggle switch 17 is on for the duration of the operation signals of the pulse disturbance isolation unit 9 or of the forming unit 11, the sound generator 21 is started, exciting the power units 25. The short-circuit protection blocks 26 maintain the operability of the alarm system with possible shorting of individual conductors aruzhnyh reproducing element 27. The third tumbler 18 connects to the electromagnetic locking device 28, the fixing drum locks and crossbars, carburettors, etc. The duration of their operation is set by the first non-inertia timer 22, triggered by the operation signals passing through the first 16, third 18 toggle switches. If the fourth toggle switch 19 is in the on state, then the second inertia-free timer 23 starts, according to the triggering signals, including the first contactor relay 29, the input pairs of contacts switch the sound and light signaling circuits. With the arrival of the response signal from the block of separation of repeated disturbances 7 to the second input of the block when the fifth toggle switch 20 is on, the third inertialess timer 24 starts, including the second contactor relay 30, opening its input pairs of contacts.

 The reset and blocking of the output of single signals by the sound generator 21 and the first 22, second 23 inertialess timers is performed as a blocking signal initiated by the contact recognition device of the trip unit 10, as well as a preset signal passing through the third input of the unit. Protective buffer elements 31-37 protect the input CMOS elements of the block circuit from breakdown in case of possible switching of the toggle switches under voltage from breakdown.

 The block of separation of repeated disturbances 7 (Fig. 4) eliminates both short-term power disturbances and random single short disturbances. The unit is turned on by the sixth toggle switch 43. With disturbances exceeding the response threshold of the corresponding comparator channel of the forming unit 11, the fourth inertialess timer 40 is started along the leading edge of the response signal of the comparator channel of the forming unit 11, setting the duration of the analysis time period for the appearance of repeated disturbances. The duration of the output response of the fourth inertialess timer is in the range of several seconds when the first switch 48 sets the operation mode according to the second external disturbance, up to several tens of seconds with a larger user-defined control number of operations. During this time, at the reset input of the first counter 47, a logic-zero level unlocking it is held. After the fourth inertialess timer 40 is triggered on the leading edge of the response signal of the comparator channel of the forming unit 11, the fifth inertialess timer 41 is started. The duration of its output response signal corresponds to the duration of the likely interference with the power supply and the duration of vibration disturbances from random single strokes of the protected objects. The number of operations of the fifth inertialess timer 41 is fixed by the first counter 47 and after the control state of its outputs is set by the user to the first switch 48, a logic unit signal appears at the second input of the first element And 42, initiating the output unit signal of the repeated disturbance extraction unit 7. Reset the fourth and fifth inertia-free timers 40 and 41 and the first counter 47 is produced by the total reset signal generated by the first element OR 42 from the preset signal at when the power is turned off, from the blocking signal, when the shutdown block 10 is recognized and from the blocking signal from power interference, which overlaps the response signal of the forming block 11. The block for isolating the sequence of short-term disturbances 8 (Fig. 5) is turned on by the user in the line for analyzing the nature of external perturbations by means of the seventh toggle switch 49. The input single operation signals of the corresponding comparator channel of the forming unit 11, which is usually configured for maximum sensitivity, odayutsya on the reset input of the second counter 63, resetting and blocking it. In the pauses between the unit input signals, the second counter 63 dials the code and periodically its final output goes into the state of the logical unit, which means that the normalized time interval of the pause between external disturbances. A single input signal, which also passes to the second input of the selector 53, starts the seventh inertialess timer 68, which sets the duration of the normalized analysis time interval for sufficient duty cycle and short duration of the external disturbance signal, while the first trigger 64 and its direct trigger are switched through the first shaper 69 the output goes into the state of a logical unit. If before the end of the operation period of the seventh non-inertial timer 68, the second counter 63 dialed a code corresponding to a sufficiently long pause, then on the leading edge of a single signal from its final output, the first trigger 64 will switch to its original state and a single pulse generated by the second driver 70 in case of a second trigger 65 in the initial state, passes to the output of the third element And 67, i.e. identifies a short-term external disturbance with a sufficiently long pause between alternating repetitions of external disturbances. If the second counter 63 did not dial the normalized pause code by the end of the operation period of the seventh inertialess timer 68, then a single pulse generated by the third driver 71 through the second element And 66 will switch the second trigger 65, and thus the third element And 67 will be in a locked state , indicating a prolonged vibrational disturbance, the exit from which is carried out after the second trigger 65 of the leading unit front formed through inversion 72 along the trailing edge e arrives at the input of the second trigger 65 inichnogo final output signal of the second counter 63. Thus, the chain of the second flip-flop 65, second AND gate 66, a third driver 71 and the inversion 72 eliminates possible false positives selector 53 at the end of protracted vibratory disturbances. The trigger signals of the selector 53 through the first element OR 55 get to the counting input of the third counter 73 and to the start input of the sixth inertialess timer 56, which releases when triggered by the reset input of the third counter 73 and determines the period of analysis of the intensity of external disturbances. With the intermittent nature of external disturbances, the series of operation of the selector 53 leads to the appearance of a single signal at the output of the second switch 74, which is the output signal of the operation of the block. The duration of this pulse signal is determined by the response time of the second OR 75 element, the reset time of the sixth inertialess timer 56, and the third counter 73. The latter is also reset and blocked through the second OR 75 element with the total reset signal coming to the second input of the block. Summing buffer 54 through the first element OR 55 can be connected to the analysis of the intensity of the signals for the selection of short-term external disturbances coming to the third input of the block from the second output of the block for extracting pulse disturbances 9. The operating modes of the summing buffer 54 are set by the eighth 50, ninth 51 toggle switches. The approximate duration of the operation cycles of the elements of the block selection of the sequence of short-term disturbances 8 is as follows. For pause analyzer 52, the frequency of the first generator 62 provides code dialing by the second counter 63 until a unit appears on its final output for about half a second to several seconds, the duration of the seventh inertia-free timer 68 is approximately two times the duration of the code dialing cycle by the second counter 63 until a unit appears at its final output from the moment of release of its reset input. The duration of the response period of the sixth inertialess timer 56 is of the order of several tens of seconds, the time providing the inefficiency of careful short-term attempts to remove or penetrate with long pauses between them.

 The impulse disturbance extraction unit with pumping of the threshold of operation 9 (Fig. 6) includes three logical chains of pumping of the threshold of operation of the first comparator 80, which is formed on the first storage capacitor 99. The current control is carried out by the logical chain of pumping with the ninth inertialess timer 91, which ensures the lowest charge intensity. It adjusts the response threshold of the first comparator 80 to slowly changing vibrational backgrounds. Repeating with the frequency determined by the discharge speed of the first storage capacitor 99, the short-term triggering of the first comparator 80 restarts the ninth inertia-free timer 91, but is quenched by the first capacitive charging circuit 97 and does not trigger the second Schmidt trigger 98. With repeated external disturbances, the output of the first comparator 80 appears longer unit pulses leading to the charge of the second storage capacitor 107 of the first capacitive charging circuit 97 to the trigger level the second Schmidt trigger 98, which in turn leads to the operation of the first single-shot 92 and to a more intense charge of the first storage capacitor 99. At the same time, a capacitor similar to the first 97 of the second capacitive charging circuit 111 of the first threshold storage 78 is charged. Parameters of the charging elements of the unit and the threshold of operation of the second comparator 115 is selected in such a way that, with the maximum intensity of the growing monotonous background, the first and second logical swap chains have time to adjust apply the voltage at the first storage capacitor 99 to the amplitude of the signals at the output of the detector 3 before the second comparator 115 trips. In the case of intermittent external vibration disturbances, the first single vibrator 92 responds quite often, which ultimately leads to the second comparator 115 the third Schmidt trigger 119. This also launches the second one-shot 93, providing the maximum charge intensity of the first capacitor 99 to the voltage level with a margin, blocking the maximum possible amplitude of the output signal of the detector 3. After that, the discharge of the capacitors of the first 97, second 111 capacitive charging chains begins against the background of the discharge of the first storage capacitor 99. For continuous continuous attempts to penetrate or remove external elements of the protected object, the output signal of the first threshold drive 78 has a pulsating "croaking" character with an irregular duration of the order of several seconds. The duration of the output signals of the ninth inertialess timer 91 and the first one-shot 92 is approximately a quarter of a second, and the second one-shot 93 is of the order of one second. The response threshold is adjusted by the first bit tuning resistor 14 of the detector 3 (FIG. 1), the first tuning potential-setting resistor 113 (FIG. 6) and the third tuning resistor 110 of the second diode-resistor charging circuit 102.

 The outputs of the first Schmidt trigger 81 also trigger the eighth inertia-free timer 84 and go to the third input of the fourth element And 125 of the digital selector for the duration of the external disturbances 77. During the response period of the eighth inertia-free timer 84, the digital selector 77 analyzes the duration of the external disturbances passing through the first comparator 80. until the first storage capacitor 99 had time to charge to the threshold of shutting off the first comparator 80. In this case, short signals due to external and network interference, as well as periodic trips of the first comparator 80, when tracking using the first logical chain paging threshold operation in accordance with the background. On the other hand, continuous monotonous output unit triggering signals of the first Schmidt trigger 81, arising from large-amplitude external disturbances analyzed by the swap element 76 and the first threshold drive 78, are eliminated. The digital selector 77 identifies only low-amplitude external vibration disturbances of an intermittent nature and works in parallel with the swap element 76 , emitting medium- and large-amplitude external vibrational disturbances. The total duration of the output single signal of the first Schmidt trigger 81 for the period of the operation signal of the eighth inertialess timer 84 is estimated using the fourth counter 121, which sums the output pulses of the second generator 122 passing through the fourth element And 125, switched by the single output signal of the first Schmidt trigger 81. In this case, the fourth counter 121 at the reset input is carried out by a logic zero at the inverse output of the eighth inertialess timer 84. If the output signal of the first Schmidt trigger 81 is quite long, then the third trigger 123 is switched by a single signal from the output of the given initial threshold of the fourth counter 121, and if the total duration of the output single signal of the first Schmidt trigger 81 during the operation period of the eighth inertialess timer 84 corresponds to the normalized time interval, then upon transition of the eighth inertialess timer 84 to the initial state through the second element OR 75 to the start input of the third one-shot 127 passes pulse of the fourth one-shot 128, switched by the single state of the direct output of the third trigger 123. At the end of the output pulse of the fourth one-shot 128, the fifth one-shot 129 is started, resetting the third trigger 123. When the output unit signal of the first Schmidt trigger 81 is delayed, the signal of the logical unit from the output of the final output the threshold of the fourth counter 121 through the fifth element OR 124 resets the third trigger 123 before the end of the reset period of the eighth inertialess timer 84 and the output unit pulses at the first, second outputs of the digital selector 77 are not formed at the moment of transition of the eighth inertialess timer 84 to the initial state. The contact interval of the outputs of the fourth counter 121 and the frequency of the second generator 122 are selected in such a way that during the period of the output signal of the eighth inertia-free timer 84, the fourth counter 121 does not have time to dial the maximum possible total code, but with a margin sufficient for reliable timing, it covers the threshold code level of occurrence the signal of a logical unit at the output of a given final threshold of the fourth counter 121. The output unit signals from the second output of the digital selector 77 sums uyutsya third capacitance charging and chain 112 when a sufficiently intense vibrating intermittent nature external perturbation voltage at the third capacitor charging chain 112 reaches the threshold of the third comparator 116 and the output of the second threshold storage unit 120 appears trigger signal. This eliminates the possible restart of the response signal of the second threshold drive 79 when operating on the sound generator 21 of the Executive unit 4. The duration of the response period of the eighth inertialess timer 84 is approximately one second. The output signals of the first 78 and second 79 threshold drives through the thirteenth toggle switch 88 the fourth element OR 83 in the twelfth toggle switch 87 are fed to the first output of the block. The thirteenth toggle switch 88 is a toggle switch for setting the operation mode only with sufficiently large-amplitude repeated external disturbances. Through the third OR element 82, the triggering signals of the first threshold drive 78 and the digital selector 77 are output to the summing buffer 54 in the case of the mode of evaluating the intensity of external disturbances over a long (up to several seconds) time interval by means of a block for isolating a sequence of short-term disturbances 8. At the same time, to achieve the maximum noise immunity eleventh 86, twelfth 98, thirteenth 88 toggle switches can be switched to open state.

 Inertialess timers (Fig. 7) are triggered by an input signal arriving at the third input of the sixth element AND 132. The start of the inertialess timer can be carried out only in the absence of a single reset signal at the second input of the sixth element OR 133 simultaneously through the first element OR NOT 131 blocking the sixth element And 132 at its second input. After switching the fourth trigger 134, the reset input of the fifth counter 135 is released by logic zero from the inverse output of the fourth trigger 134 and the fifth counter 135 starts dialing the code, summing the pulses arriving at its counter input from the output of the third generator 136. When a unit appears at the final output of the fifth counter 135 the sixth AND 132 element is blocked through the first OR-NOT 131 element, and the fourth trigger 134 is reset through the sixth OR 133 element, causing a subsequent reset of the fifth counter 135, after which the sixth And 132 element unlocks The inertialess timer is also ready for a new switching cycle.

 The shutdown unit 10 (Fig. 8) allows you to turn on / off the alarm system by switching power using a group of parallel secret toggle switches 138, and also allows you to temporarily block using a contact identification device, transmitting half of which the owner carries with him.

 The operation mode of the shutdown unit 10 is set by the fourteenth toggle switch 139. This is either a shutdown mode only by a group of parallel secret toggle switches 138, or a shutdown mode by the toggle switches 138 with the possibility of temporary blocking by the contact recognition device. If the device is blocked by contact recognition at the moment of contact of the transmitting contact plug 140 with the contacts of the receiving contact socket 145, the voltage from the output of the third stabilizer 147 through the fifth protective resistor 146, the smoothing resistive-capacitive filter 141 and the second stabilizer 142 goes to the power input of the encoder 143 of the transmitting half . At the output of the latter, code bursts appear at the input of the output modulator 144. Low-amplitude code fluctuations in the supply bus between the output of the fifth protective resistor 146 and the input of the smoothing resistive-capacitive filter 141 through the second isolation capacitor 148 enter the input of the second amplifier 149, where they are amplified and then the fourth shaper 150 is converted into logical signals, the sequence of which is analyzed by the decoder 151. In case of coincidence with a given code combination at the output, the decoder A single pulse signal appears on RA 151, which repeats as the code packets arrive from the transmitting half of the contact identification device, which leads to the charge of the capacitive storage 152 to the upper threshold of the fifth Schmidt trigger 153. The signal of the logical unit, the output of which is held until the discharge of the capacitive storage 152 to the lower release threshold, which occurs after the contact is broken between the transmitting and receiving halves of the contact identification device. During the operation of a single signal at the first output of the unit, it is necessary to get into the protected area and turn off the corresponding toggle switches 138, or it is necessary to leave the transmitting and receiving halves of the contact identification device in a switched state, so that during a short visit to the protected area there is no unnecessary alarm system operation. In the case of a shutdown mode only by a group of parallel secret toggle switches 138 by means of the fourteenth toggle switch 139, the power of the contact identification device is turned off.

 The response mode to external disturbances to the forming unit 11 (Fig. 9) is set by the eighteenth toggle switch 172, which determines where the start signal from the forming unit 11 comes from or from the seventh Schmidt trigger 164 for each external disturbance, which causes the fifth threshold of the comparator 162 to be exceeded, or through the ninth OR element 167, through allocation blocks 7-9. The seventeenth toggle switch 171 in the switching position of its movable contacts with the second fixed contacts of its sections sets the operation mode with a delay to enter the protected area and to subsequently turn off the power through the shutdown unit 10. In this case, the signal from the movable contact of the eighteenth toggle switch 172 through the seventh element And 154 , through the second section of the seventeenth toggle switch 171 and through the ninth element And 156 starts the twelfth inertialess timer 159, which sets the duration of the delay for operation. At the moment of the end of its output pulse, a single pulse is issued through the fifth shaper 177, through the first section of the seventeenth toggle switch 171 and through the seventh element OR 165 to the start input of the tenth inertialess timer 157. The tenth non-inertia timer 157 that has started up gives a triggering signal to the third output of the block and at the same time triggers a blocking passage through the seventh element And 154 of subsequent single triggering signals, the eleventh non-inertia timer 158, the output of which with a margin of time overlaps the output signal of the tenth non-inertia timer 157, and through the eighth element OR 166 blocks the twelfth inertialess timer 159 at the reset input, the additional blocking of the restart of which is carried out by locking 9th element And 156 zero signal from the inverse output of the thirteenth inertia-free timer 160, triggered by the output signal of the twelfth inertia-free timer 159. The duration of the signal of the thirteenth inertia-free timer 160 with a margin overlaps the total duration of the eleventh 158, twelfth 159 inertia-free timers. Due to this, possible interfering restarts of the cycles of issuing the operation signal in the delay mode are eliminated. In the position of switching the movable contacts of the seventeenth toggle switch 171 of the first stationary contacts of its sections, the chain of the twelfth 159, thirteenth 160 inertialess toggle switches is turned off, and the start signal from the movable contact of the eighteenth toggle switch 172 through the seventh element OR 154, through the first section of the seventeenth toggle switch 171 and through the seventh element OR 165 is fed to the trigger input of the eleventh inertialess timer 157 and thus the trigger signal of the forming unit 11 is triggered without delay. The eighth element And 155 provides a quick response mode of the alarm system to external disturbances during the presence at the fifth input of the block of a zero absence signal fixed for a specified time from the output of the probable absence timer 13. The twenty-first toggle switch 175 allows you to set a constant accelerated response mode initiated by allocation blocks 7-9. The preset signal and the blocking signal, respectively, arriving at the sixth, seventh inputs of the block through the tenth element OR 168, block the tenth inertialess timer 157 at the reset input, and through the eighth element OR 166 and the twelfth inertialess timer 159. The nineteenth toggle switch 173 switches the response signal by repeated external disturbances, either at the first input of the ninth element OR 167, or at the fifth output of the block. The twentieth toggle switch 17 allows you to quickly set one of a pair of pre-selected thresholds for the fourth comparator 161 in accordance with the conditions of the likely vibrational background. The twenty-second toggle switch 176 allows you to connect the block allocation of repeated perturbations 7 to enable the Executive unit 4 to break the external circuits and at the same time triggering an audible alarm and electromagnetic blocking of the external actuators. In the lowered position of the fifteenth and sixteenth toggle switches 169 and 170, the signal from the output of the detector 3 is fed to the inverse inputs of the fourth and fifth comparators 161 and 162, the direct inputs of which are connected to the middle terminals of the third, fourth and fifth tuning potential resistors 179-181. In the switching position of the movable contacts of the fifteenth and sixteenth toggle switches 169 and 170 with their second fixed contacts, the inputs of the fourth and fifth comparators 161 and 162 are connected to the noise suppressor outputs in such a way that the average input voltage level generated at the third storage capacitor 194 is supplied to the direct inputs , and to the inverse inputs of the fourth and fifth comparators 161 and 162 a signal meander is smoothed somewhat at the fourth storage capacitor 195, the output amplitude of which Ask about the adjusted sensitivity comparator channels sixth and seventh trimmers potentsialozadayuschimi resistors 182 and 183.

 This alarm system is designed to protect a wide range of objects. For each of these objects, its own individual set of modes and functions of the alarm system is optimal. So for door and garage alarm devices, it is enough to have one unit for isolating impulse disturbances with pumping of the operation threshold. For vehicle protection, simultaneously operating the block of separation of impulse disturbances with pumping of the threshold of operation and the block of allocation of a sequence of short-term disturbances are suitable. If the car is left in a quiet place or garage, then for greater security protection, the block of repeated disturbances can also work. The repeated disturbance extraction unit is applicable for initiating an ignition circuit break. In the microphone alarm system for indoor security, analyzing and emitting the sounds of steps, the joint operation of the block of impulse disturbance extraction with pumping of the threshold of operations and the block of isolating the sequence of short-term disturbances is effective.

 A wide selection of modes and functions incorporated in the design of this alarm system, allows for high reliability protection of a wide range of objects.
