In addition, input sensors reacting to flame combustion are introduced into the system - a flame combustion sensor, for example, an infrared and / or smoke sensor, for example, optical, the outputs of which are connected to additional inputs of the control unit, while the accelerometer signal is inverted in the control unit. The system can be used as an autonomous fire and security alarm.

To provide the possibility of testing the system’s health through a radio channel, an input radio receiver with a decryptor connected in series is additionally introduced into it; output

In the system operating as an autonomous fire and security alarm device or an autonomous fire and security alarm sensor, an electromagnet and / or electric detonator are additionally introduced, the inputs of which are connected to the additional output of the control unit.

In addition, a radio receiver unit, an encoder and a decoder can be added to the system, and the output of the radio transmitting unit is connected to the input of the decoder, the output of which is connected to the additional input of the control unit, one of the additional outputs of the control unit is connected to the decoder, the other additional output of the control unit is connected to the encoder, one of the encoder control outputs is connected to an additional input of the control unit, and the decoder output is connected to the modulator input, the triggering algorithm is supplemented Bani control unit to transmit the coded signal "a" for help when advance notice signal "a" from the search station, using the first encryption stage or multiple-decoding.

In addition to the autonomous fire and security alarm device and the autonomous fire and security alarm sensor, an input device is added: a pulse meter, the output of which is connected

to the additional input of the control unit, which provides the ability to track the status of the owner of the system is combined: using a motion sensor and a pulse meter.

FIG. 7 shows a fragment of a structural diagram of the system of FIG. 1, 2 or 6, supplemented by a pulse meter (PI) 18.

The device shown in figure 1, operates as follows. BU 5 in standby mode ACC 1 monitors signals from the input devices DD 2, TD 3, CPV 4. If there is no DD 2 signal for a fixed time or when ACC 1 is at elevated temperature for a time dependent on the ambient temperature monitored TD 3, BU 5 includes AI and SI 6. After a fixed time, if the signal from DD 2 is not received, BU 5 turns on RPB 8. When activating the CPV 4, BU 5 turns on simultaneously AI and SI 6, RPB 8. RPB 8 is modulated by M 7 , to which the signal is supplied from the additional output of the control unit 5. Thus, effective notification by radio signal about help in extreme situations: danger, life threatening and (or) state of health of the ACC 1 owner, and in some favorable cases, localization of the coordinates of the ACC 1 owner when using a narrowly directed receiving antenna and (or) several radio receivers is printed.

The device shown in figure 2, when triggered DD 2 and TD 3 works similarly to the device presented in figure 1. When activating KPV 4, BU 5 simultaneously turns on AI and SI 6, RPB 8. KPV 4 supplies the supply voltage to Mik 9. M 7 in this case is modulated by the output signal from Mik 9. Thus, the owner of ACC 1 can independently send a signal for help with a speech message .

The device shown in Fig.3 works as follows. BU 5 in standby mode ACC 1 monitors signals from input devices DD 2, TD 3, CPV 4, DZ 10 and / or DPG 11. If there is a signal DD 2 for a fixed time or when ACC 1 is at an elevated temperature over time depending on the ambient temperature monitored by TD 3 or when DZ 10 and / or DPG 11 are triggered, BU 5 includes AI and SI 6. After a fixed time, if DD 2, TD 3, KPV 4, DZ 10 and / or DPG 11 still activated, control unit 5 includes RPB 8. When activating the CPV 4, control unit 5 simultaneously includes AI and SI 6, RPB 8. RPB 8 modulates I 7 M, to which a signal output from the ECU 5. Thus, the ACC 1 is provided by work as an autonomous fire-security alarm set, for example, in the non-electrified area.

The device shown in Figure 4, when triggered DD 2, TD 3, CPV 4, DZ 10 and / or DPG 11 works similarly to the device shown in Fig.Z. Additionally introduced RPrB 12, D13iSh14. The input signal to the modulator is supplied from output Ш 14, the input of which

connected to one of the outputs of the control unit 5. Upon receipt of the radio signal RPRB 12 and recognition of its D 13, the latter generates an output signal supplied to the additional input of the control unit 5. BU 5 in this case immediately includes AI and SI 6, RPB 8. Encoding Ш 14 may be different depending on the operation of the input devices DD 2, TD 3, KPV 4, DZ 10 and (or) DPG 11, RPrB 12. Thus, the ACC 1 is provided as an autonomous fire alarm sensor installed, for example, in non-electrified room. Thanks RPrB 12, D13iSh14 possible remote testing of this sensor fire alarm. Also, the presence of D 13 and W 14 allows you to identify ACC 1 when using several similar devices.

Figure 5 shows a fragment of the structural diagram of ACC 1 of Fig.Z or 4 with additional input EM 15 and / or ED 16, the inputs of which are connected to the additional output of control unit 5. ACC 1 in the presence of a signal with DD 2 or CPV 4 and no signals with TD 3, DZ 10 and / or DPG 11 works similarly to the devices shown in Fig.Z or 4. If there are signals with TD 3, DZ 10 and / or DPG 11, ACC 1 also works similarly to the devices shown in Fig.Z or 4, but at the same time in parallel BU 5 begins to track signals from DD 2 or CPV 4. If there are signals from DD 2 or CPV 4 received after signals from TD 3, DZ 10 and / or DPG 11, BU 5 sends a signal to EM 15 and / or ED 16, which initiate the destruction (using ED 16) or removal from fixation (using EM

15) fastenings of enclosing protective structures, for example, window grilles. Thus, in case of fire, free access to the guarded room with protective structures is provided for the penetration of rescue personnel and (or) evacuation of victims.

The device shown in Fig.6, operates as follows. BU 5 in standby mode ACC 1 monitors signals from input devices DC 2, TD 3, CPV 4, RPrB 12 with D 13. If there is no DC 2 signal for a fixed time or when ACC 1 is at an elevated temperature for a time dependent from the ambient temperature monitored by the TD 3 or when the KPV 4 is activated and at the same time when there is a coded radio signal “own” PRS 17, received by RPrB 12 and recognized by D 13, BU 5 includes RPB 8, the output signal of which is modulated by Ш 14. After a while, BU 5 transfers ACC 1 original state, i.e., RPB 8 is turned off, and control unit 5 monitors the signals DD 2, TD 3, KPV 4, RPrB 12 with D 13. Further, if communication is established with ORS 17, the cycle repeats. When approaching the PRS 17 at a certain distance, with the above factors, and, accordingly, increasing the level of the input radio signal, Rprb 12 generates an output signal supplied to an additional input BU 5, which in turn includes AI and SI 6. Thus, ACC 1 operates in the short-term mode only if there is a radio signal of “its own” search radio station, which is optimal, for example, during military operations with a hidden search for the wounded and injured. Luminous and

ACC 1 audible signals are turned on only when the ORS 17 is in close proximity. When supplementing the BU 5 operation algorithm and using D 13 and Ш 14 with two or more encryption levels - decryption, a greater degree of protection against unauthorized search is possible, for example, using the following algorithm: 1) transmitting the “code 1 PRS” signal from the PRS 17, 2) receiving the signal “code 1 PRS” to ACC 1 and the operation of any of the input devices DD 2, TD 3, CPV 4, 3) transmitting the signal “code 1 ACP” from ACC 1 4) transmitting the “code2ACC” signal from ACC 1, 5) receiving the “code2ACC” signal to the PRS 17, 6) receiving the “code2P” signal PC ”on ACC 1, 7) transmission of the“ ACC code 1 ”signal from ACC 1. With the correct passage of the entire sequence of signals according to the above algorithm, ACC 1 emits a radio signal for a fixed time. Next, the cycle repeats. If there are several unsuccessful attempts to exchange “your own” codes, BU 5 ACC 1 disables BPM 8. In this case, even with unauthorized transmission of the signal “PRS code 1”, obtained, for example, using radio interception, ACC 1, without receiving the “code2PRS” signal will stop transmitting the radio signal. The use of the device shown in Fig. 5 is optimal when searching for the wounded and injured using a low-flying aircraft, on which ORS 17 is installed, and when localizing the coordinates of the injured - using ground-based means.

In Fig.7 shows a fragment of the structural diagram ACC 1 of Fig.1, 2, 6 or 8 with an additional input IP 18, the output of which is connected to an additional input of control unit 5. Control unit 5 when all input

devices, except DD 2, works similarly to that described above. In the absence of a signal from DD 2, BU 5, the output signal from IP 18 is evaluated. If the frequency and (or) heart rate adopted by IP 18 is outside the normal range, BU 5 provides output devices that are triggered by algorithms similar to those for DD2 devices, described above. Thus, false alarms with low mobility of the ACC owner are minimized.

Fig. 8 shows a fragment of the ACC 1 structural diagram of Figs. 1-7 with an additional RCT, the inputs of which are connected to the input M and a separate output of the control unit. Thus, it is possible to connect an external device having its own radio signal transmitter, for example, a cell phone .

It is possible to test the control unit 5 of the supply voltage of the built-in self-contained ACC 1 power supply as shown in FIGS. 1-8 and turn on the output devices, for example, AI and SI 6, when the supply voltage is lower than critical.

Thus, when using these devices, the warning range increases by a signal of assistance to the victim or of an extreme situation, in some favorable cases, the location of the victim's coordinates is possible, the scope of these devices is expanded.
