The matching unit (Fig. 2) consists of resistors 44-49 and diodes 50-52. The alarm unit 33 (FIG. 3) contains light-signaling nodes 53 by the number of alarm channels 1, consisting of amplifiers 54-57 and elements 58-61 display, and common to all channels i of the alarm siren alarm 62.

The device works as follows.

Perek: pobertelek 35 operating modes

Two modes are provided. Functioning: Work and Prevention.

In the operating mode, after switching on the device, the unit-level signal from the operation mode switch 35

It is fed to the second inputs of the elements AND of all signaling channels and opens the keys. In the absence of alarm conditions, pressing the button 34 is set to zero.

the state of the flip-flops 30-32 of the memory of all channels I of the alarm device. In this case, the zero-level signal from button 34 (via element 24 OR goes to the R-input of memory flip-flops 30-32 and resets them to the zero state. At the same time, the signal goes to the second input of element 4 AND, which in the absence of alarm conditions closed

the level of the zero signal at the first input coming from the cell output. 18 FPI does not trigger the one-shot 28, which starts 3

It is only on the front of a single level signal. Therefore, at the output of element 29, a signal of a single level is NOT stored, which is fed to the C inputs of the trigger 30-32 memory

not affecting the state of the latter, since the B-triggers respond to information

signal only at the moment of signal change on the C input from 0 to 1 The zero level signals from the direct outputs of the memory trigger 30 and 31 are received respectively at the inputs of the amplifiers 55 and 56 of the corresponding 53-light signaling unit of the alarm system 33 from the direct output the trigger 32 of the memory signal O through element 13 And is fed to the input of the amplifier 57 corresponding to this channel 1 signaling of the light signaling unit 53 of the signaling unit 33 In this case, the display elements of the signaling unit 33 are not lit The device is ready to work with sensors 2 and 3 s persecuted. The status information of each monitored object, coming from the signaling channels 1, is collected in the information collection unit 41 and fed to the audible alarm 62 in the signaling unit 33. The state of each object is characterized by information received from the contact sensors 2 and 3 of the signals over a three-wire communication line. Information at the sensor output

2 and 3 are represented as two discrete values: 1 and / or O. Switching the states of sensors 2 and

3 is carried out simultaneously and only with the presence of a control action or after its removal (return to the initial state),

In the device, the following types of control are possible, determined by the states of the contacts of sensors 2 and 3 and connecting lines 4-6 of communication, regardless of the states of the contacts of sensors 2 and 3:

-control of the initial state of the sensors at which Open 4 is closed 5 is closed

-control of the emergency state of the object, in which 4 is closed - closed 5 - is open.

- control of sensor failure, in which Open, uta 4 - closed 5 - open 6 or Closed 4 - open 5 - closed

- control of the fault of the communication line, during which 4–6 are open (communication lines are broken outside the object) or 4 - 6 are closed (a short delay of communication lines outside the object),

The initial state of the sensors 2 and 3, in which 4 is open - closed 5 - closed 6, is characterized by the binary code 100 ,. coming from sensors 2 and 3 through the lines

4-6 connection to the inputs of the assembly 7 unit (Fig. 2). In block 7, the ratio of the resistance values of the resistors 44 and 45, 46 and 47, 48 and 49 provides, depending on the state of the contacts, the voltage of the power supply 4. sensors 2 and 3, of a single or zero signal level, which through elements 9-11 AND 15-17 and OR arrive at the inputs of the decoder 26; If there is a code 100 at the input of the decoder, the control signal of the unit level is generated at the sixth output the input of the alarm unit 33 and through element 54 causes display element 58 illuminates the initial state of the sensors.

The emergency state of the object in which Closed 4 is closed 5.- open 6 characterizes the code 001 coming from sensors 2 and 3 to the inputs of the decoder 26 along circuits analogous to the passage of signals when monitoring the initial state of sensors 2 and 3. In this case The first output of decoder 26 is a signal of a single level, which through element 19 OR is fed to the C-trigger of memory 30 (alarm) and simultaneously through an open element 1.2 AND, at the second input of which there is a single-level enable signal with inverse the first output of the memory trigger 30, through element 18 OR to element 14 I, at the second input of which there is a single level signal from the output of element 24 OR, - On the positive edge of the signal of the single level from the output of element 14 I, a one-shot 28 is started, at the output of which a pulse of positive polarity with a duration determined by the necessary delay to prevent spurious scientific research institutes of memory triggers 30-32 from the contact of sensors 2 and 3 in the transducer

the trip mode and, in addition, protection of the triggers 30-32 from possible impulse noise in lines 4-6 of communication is provided. Along the trailing edge of a pulse formed by a single vibrator

28 and inverted element.

29, clocking is not performed on the C-input of memory triggers 30-32.

As a result, present at the D input of memory trigger 30, information i passes to its output, it is remembered and at the same time self-blocking of the trigger 30 by a zero signal from the inverse output at the 3-input of the installation into 1. The same zero signal through the element 12 And the first input of element 18 OR is received, ensuring its switching in case of other emergency situations - faults of sensors 2,3 or communication lines 4-6 arising after an accident Single level signal from the direct output of trigger 30 of memory through the element 23 OR enters the information collection unit 41, where through the OR element 42 and the control element 43 is fed to the first input of the alarm unit 33 and a warning signal 62 is generated. At the same time, the unit alarm signal from the direct output of the memory trigger 30 goes to the third input of the alarm unit 33 and through the amplifier 55, the element Avarion’s display element 59 is ignited. The sound is turned off by pressing the sound lock button 342 of the information collection unit 41. The communication structure and the organization of the memory trigger 30 are considered to ensure the storage and storage of information about an emergency condition in the absence of an operator. Triggers 31 and 32 of memory work similarly. If the fixed 1 crash of the object is eliminated, then the condition of the sensors changes to the initial one. In this case, in block 33 of the alarm, along with the luminescence of the accident indicator 59, the indicator 58 lights up. The initial state of the sensors. At the same time, the operator presses the button 25 for selectively resetting the control signal generation unit 8 of this signaling channel 1 and the zero level signal through the OR element 24 and along circuits similar to passing from the general reset signal — by setting

The trigger 30 memory is in the zero state. In this case, the element Avari's indication 59 goes out in the alarm block 33 and the buzzer 62 stops functioning if it has not been previously turned off. The circuit is ready to receive the next alarm. If in the time interval of the selective reset action, the duration of which may be several seconds, after setting the memory trigger 30 to the zero state, the next emergency state of the object occurs, in this case, at the U input of the memory trigger 30 and at the first input of the element 14 And there will be single level signals. In this case, at the end of the selective reset signal (on the back of its front), the one-shot 28 is started and the impulse is formed. On the falling edge of the inverted element 29 of the NOT pulse of delay, a new information about the accident is entered into the memory trigger 30 and into the signaling unit 33.

The faults of sensors 2 and 3, in which 4 is open - closed 5 - is open 6 or closed 4 - is open 5 - closed 6 is characterized by codes 101 or 010, respectively, which occur when communication lines 4 and 6 are short or short-circuited. object due to unresolved contact states of the Z and 3 sensor groups during their deformation. The specified unresolved states of the switching contact groups of sensors 2 and 3 may occur after the initial state, if there is a controlling influence at the moment of the object accident and after an emergency at the moment of removing the controlling influence, In the first case, if after the initial state of the sensors 2 n 3 at the time of the object's accident, instead of the emergency code 001, a code 101 will appear or, arriving at the inputs of the decoder 26, a control signal is generated at its second or third output, which, through element 20 OR, goes to the D input of memory trigger 31 vnosti sensors, and through OR element 8, the element 14, and N front-edge delay unit 27 - i-ra its C -Log, providing memorizing informahschi about He7

sensors 2 and 3 are operable. In this case, the unit-level signal from the direct output of the memory trigger 31 goes to the fourth input, and through the OR element 24 and the information collection unit 41 to the first input of the alarm unit 33, where the buzzer 62 is triggered and the element 60 indications Malfunction of sensors At the same time, the signal of a single level of an output of an element 20 OR in the absence of an object crashes through an IZH element 19 opened by a zero signal from the first output of the decoder; 26, 3) - trigger memory 30 and similar In the event of an accident, the memory is triggered by the memory trigger 30, and in block 33 of the alarm, the element 59- indication of the object Avari is illuminated. In block 33 of the alarm, in this case, the elements 59 and 60 of the indication are malfunctioning of the sensors and the Avari of the object. If there is an object alarm condition characterized by code 001 and the control action is cleared, instead of the initial state code 100, code 101. or 010 occurs. In this case, the zero signal from the inverse output of memory trigger 30 passes through element 12 And to the first the input of element 18 OR and ensures that the control signal passes from it from the output of element 20 OR to the input of node 27. In the future, the operation is similar to that considered, while in block 33 of the alarm, along with the burning of the indication element 59, the object's Avar lights up display element 60 Sensor failure.

The faults of the communication lines 4–6, with which 4–6 or 4–6 are closed, are open or short respectively.

short circuits of communication lines outside the object (or at its output) are characterized by codes 111 or 000. In case of failure of lines 4-6 of communication and receipt of the corresponding codes I 1 1 or 000 ot of communication lines 4-6, to the inputs of the decoder 26, at its fourth or fifth outputs, a control signal is generated, which through element 21 OR enters the second D input of memory trigger 32 (communication line faults), and through element 18 OR and the front signal delay node 27

on its C-input, ensuring the memorization of information about the malfunction of communication lines. The unit level signal from the direct output of the trigger 32 of the memory through the element 23 OR and the information collection unit 41 is fed to the first input of the alarm unit 33 and causes the sound of the audible alarm 62. At the same time, the unit level signal from the direct output of the trigger 32 of the memory, which is common symptom of faults in the communication lines, passes through element 13 I, opened with a single level signal from the output of element 22, OR, the second input of which is connected to the open contact of the button 40 to control the line faults and enters the fifth input d alarm unit 33, wherein the indicating member 61 vysvechgshaets link fault. At the same time, in order to clarify the nature of the malfunction of the communication lines 4-6, the operator presses the line failure control button 40. Moreover, if the code is 000 (short circuit), then the first input of the element 22 OR is set to a single level signal from the fifth output of the decoder 26 and the low frequency signals from the output of the signal generator 39 do not pass through the OR element 22. As a result, the illumination of the display element 61 does not change. If the device has the code 111 (communication link), then the first input of element 22 OR is a zero level signal that transmits low frequency signals from signal generator 39 to the fifth input of alarm unit 33 through open element 13 I. At this, element 6 of the display is lit up with a break, which tells the operator about the presence of a broken communication line. When the button 40 is released, the indicator 61 is lit with a constant light. If malfunctions of lines 4-6 of communication occur after an object has crashed, in this case in block 33 of the alarm along with the indicator 59 lights up. The object's indicator lights up 61 The line is faulty. After the malfunction of sensors 2 and 3 or lines 4-6 of communication and resetting to the initial state is eliminated, a selective reset of the trigger 30-32 of the memory of this signaling channel 1 is performed, as a result of which the corresponding g9 will go out

Indicator block 33 indicators. Other channels work in a similar way. For each channel a, a general audible warning is used and individual light indications are included in the composition of the individual nodes 53 of the signaling unit 33, serving each channel, which ensures simultaneous and independent operation of the channels with ignalization.

The control of the I operation of the device is carried out in the Prevention mode, which is set by the switch 35 of the operation mode by applying a zero signal to the second inputs of elements 9-11 and all signaling channels. In this case, it is possible to set the required combination of days at the second inputs of elements 15-17 OR and at the same time check the functioning of all elements of the alarm system with the appropriate types of control.
