Depending on the state of the operation mode switches 10 control 9, the device operates in the following modes: mode 1 - control of the unresolved state of an object using light signaling and audible alarms; mode 2 - end Trol of unresolved state of an object with a help of light with a hint of power} mode 3 - control of the information collection unit 7 of the signaling unit 8. The state of the object is characterized by information from two sensors 2.

Under control of these signals, a high voltage level is generated on the collector of transistor 50 of the first matching node 44, and A second low-voltage signal is generated in the transistor 50 of the second junction 44. These signals through the outputs 16 and 17 of the matching unit 3 arrive at the first and second INPUT of the control signal generating unit 4 and the control unit b. control data signals are inverted and as a result, the outputs of elements 51 and 52 do NOT form signals respectively .HVi3Koro and high voltage levels, which are received respectively at the first inputs of elements 53 and 54 AND-NOT and outputs 24 and 25 of the signal generation unit 4 This control unit receives signals from these signals to the third and fourth inputs of control unit 6, respectively. The other inputs of the elements 53 and 54 of the NAND receive signals from the inputs 17 and 16 of the unit 4 for generating control signals of the low and high voltage levels, respectively. As a result, at the outputs of elements 53 and 54 AND-NOT, signals of respectively high and low voltage levels are generated.

The G output of the 53 element IS-NOT. The high voltage level signal is fed to the first input of the element 56 OR-NOT and the element 57 WI-NO, and also through the element 55 DOES NOT prohibit the trigger 60 from being set to one. From the output of the element 54 AND-NOT, the low voltage signal is inverted by the element 57 OR NOT and is fed to the output 26 of the control signal generating unit 4, and then to the input of the input transistor switch made on the resistor 61 and the transistor 62 of the pulse selector 5 (FIG. As a result, a low voltage level signal is generated on the collector of transistor 62, under which the output transistor switch- on performed on elements 67 and 68 is closed, and a high voltage signal is generated on the collector of transistor 68. This signal through pulse 20 of selector 5 pulses is fed simultaneously to the second input of element 56 OR-NOT, to the sixth input of control unit 6 and to the corresponding input of element 71 OR-NOT of information collection unit 7 (Fig. 67. At the output of element 56 OR - A low voltage signal is not generated, which prohibits the formation of a signal at the output of the imaging unit 58 and simultaneously arrives at the output 23 of the control signal generating unit 4, and then through the element 72 OR-NOT and the output 32 of the information collection unit 7 is fed to the input of the amplifier 78 block 8 signals Atsii Fig. As a result, the lamp 85 (enabled state.) Turns on under control of this signal.

In block 6 of the control (figure 2) on the first, second, third, and fourth. fifth inputs of the first element

42 AND-OR-NOT signals of a respectively low, high, high, low, and low voltage are received. As a result, a high voltage signal is generated at the output of element 42 AND-OR-NOT, which is fed to the corresponding input of element 73 OR-NOT of information collection unit 7 (FIG. 6). If the other inputs of element 73 OR are received similar signals, lamp 86 (control 1) is off.

The first and second inputs of element 43 AND-OR-NOT receive signals of a high voltage level from inputs 26 and 30 of control unit 6, and the third and fourth inputs receive inverted data signals by elements 40 NOT | and 39 NOT. .

As a result, the output element

43 OR-OR-NOT produces a low voltage level signal which is inverted by the 41 element NOT and is inputted to the output 28 of the control unit 6, and then to the corresponding input of the element 74 OR the NOT information collection unit 7 When: high voltage signals are present on the remaining inputs of the element 74 OR-NOT of the information collection unit 7, the alarm lamp 87 (control 2) is off.

The operation of the device in mode. 1 in the case / when the information coming from the sensors 2 characterizes the unresolved state of the object.

When this state of an object occurs with the help of resistors 45 in the first and second junctions 44 of the junction of the matching unit 3 and the contacts of the first and second sensors 2, the inputs of the unit 13 and 12 of the jogging unit generate signals of the logical unit and logical zero, respectively The 46 and | 48 first and second voltage conductors 44 are fed to the inputs of transistor switches made on the resistor 49 and the transistor 50. Under the control of these signals on the collector of the transistor 50 of the first node 44 of the conjugation a low voltage signal, and a high voltage signal is generated at the collector of the transistor 50 of the second junction 44. These signals through the outputs 16 and 17 of the matching unit 3 are fed to the first and second inputs of the control signal generating unit 4 and the control unit 6. In block 4 of generating control signals, these signals are inverted by elements 51 and 52 NOT and, as signals of a high and low voltage, respectively, arrive at the first inputs of elements 53 and 54 of AND-NOT and outputs 24 and 25 of block 4 of generation of control signals, and then to the third and fourth inputs of the control block b. The second inputs of the elements 53 and 54 of the NAND receive signals from the input 17 and 16 of the unit 4 for generating the control signals of a high and low voltage, respectively. In the results, at the outputs of elements 53 and 54 AND-NOT, a signal is generated correspondingly of low and high voltage levels, which is fed to the inputs of elements 56 and 57 OR-NOT. In addition, this signal is not allowed by the inverting element 55. Trigger 60 installation (audible signaling in one state. At the output of element 57 OR-NOT, a high voltage level signal is generated that goes to the input of the selector for 5 pulses and to input 26 of the control block b. At the output of the selector 5 pulses, like in the previous version (mode 1) there will be a high voltage level signal which, through the output 20 of the selector 5 pulses, simultaneously arrives at another input of element 56 OR NOT, at the sixth input of control unit b and at input of element 71 OR NOT of information collection unit, do not light the lamp 84 f At the output of element 56 OR-NOT, a high-level signal is generated, under control of which the lamp 85 (enabled state) goes out in alarm block 8, and at the output of signal generator 58, a signal is generated from the leading edge y that sets the trigger 60 ) in a single state. As a result, at the output of the element 59, the AND-NOT generates a low voltage signal which, through the output 22 of the control signal generating unit 4 and the element 70 OR-NOT of the information collection unit 7, is fed to the input of the audio signaling control unit 75. At the output of block 75, an audio signal is generated, which triggers the sound of loudspeaker 81 and attracts the attention of the operator. In addition, from the zero input of the trigger 60 (| audible alarm the low voltage signal through the output 21 of block 4; the generation of control signals and the element 69 of the OR-NOT block .7 information is fed to the input of the amplifier; the 76 of the alarm block 8, which causes lamp 83 to fire. {Unresolved state. In control unit 6, the first and second inputs receive low and high voltage signals, and the third, fourth and fifth inputs receive high, low and low voltage levels. As a result, the lamps 86 and 87 (control 1 and control 2) not hot. The operator using the reset button 11 can set the trigger 60 (sound signaling to the zero state, thereby dimming the lamp 83 and stopping the sound of the loudspeaker 81 of the alarm unit 8. The device operates in mode 1 when it is information, act from sensors 2, characterizes the allowed state of the object in case of failure of any element in the block, control signal generation 4. If this situation occurs, the output 26 of the control signal generation unit 4 will have an unusual voltage level and for this mode of operation, i.e. The inputs 16 and 17 of the control signal generation unit 4 will be signals of a high and a low voltage, respectively, and at output 26 a low level signal. As a result of these signals being received, respectively, the first, second and fifth inputs of control unit 6 and low and high voltage signals, respectively, to the third and fourth inputs at the output of element 42 AND-OR-NOT, a low voltage level signal will be generated. This signal through the output 27 of the control unit 6, the element 73 OR and the output 33 of the information collection unit 7 is fed to the input of the amplifier 79 of the signaling unit 8. Under control of this signal, lamp 86 lights up (control 1). A similar situation occurs when the elements of this block fail in other variants of mode 1. The device operates in mode 1, and the information from sensors 2 characterizes the allowed state of the object if any element in the pulse selector 5 fails. If this condition occurs, the input 20 of the pulse selector 5 will have a signal of an unusual voltage level for this variant of the device operation mode, i.e. at signal

a high voltage level at the input 26 of the pulse selector 5 at the output 20 of it will be a low voltage signal. When these signals arrive at the ground of the element 43 AND-OR-H, the output of the element 41 will NOT generate a low voltage signal which, through the output 28 of the control unit b, the element 74 OR-NOT and the output 34 of the information collection unit 7 to the input of the amplifier 80 unit 8 signaling. Under control of this signal, lamp 87 lights up (control 2) ..

A similar situation occurs when this unit fails in other versions of the 1.15 mode.

Operation of the device in mode 2 is characterized by the fact that the operator sets the .10 switch of the operating mode to the Closed position. In this case, a logical zero is applied to the first and second pins 20 of this switch 10. As a result, the lamp 82 (operation without an audible alarm) lights up in the alarm block 8 of FIG. 7, and the input element 59 is NOT 25

control signal generating unit 4 A low voltage level signal is constantly supplied, thereby blocking the formation of an audible alarm trigger signal. Otherwise, the operation of the device in this mode is similar to the operation in mode 1.

The operation of the device in mode 3 is characterized by the fact that the operator sets the control switch 9 to the Closed position. As a result, a logical zero signal is applied through elements 69 OR-NOT, 71 OR-NOT, 72 OR-NOT, 73 OR-NOT and 74 OR-NOT of the information collection unit 7 to the inputs of the respective amplifiers 76-80 of the unit. 8 alarm. Under the control of these signals, the corresponding Lamps 82-87 light up, which characterizes the health of the information collection unit 7 and the signaling unit 8.

The economic effect of the use of the invention is due to its technical features as described above.
