The purpose of the invention is to increase the information and accuracy of the device.

The drawing shows the functional diagram of the device.

Each of the channels of the device contains the first and second sensors I and 2 of the decoder 3 and the scaling unit 4. In addition, the device contains the first and second elements OR 5 and 6, the reversible counter 7 and the counter 8.

Scaler 4 contains the first and second triggers 9 and 10, the first to the ninth elements AND 11 - 19, the first, second and third elements OR 20,21 and 22, the third trigger 23, the element OR-NOT 24, the tenth and eleventh elements are both 25 and 26, fourth and 11TH trigger triggers 27 and 28.

The device works as follows.

In the initial state, all the triggers of the enumeration blocks 4, as well as the counters 7 and 8, are in the zero state, in which the OCI before the start of work are installed using an initial setup block (not shown), while at the outputs of the elements OR-ИЕ 54 and elements 11 and 12 are levels O. In the case of a moving object in the zone of the sensor or 2 (its overlapping), signal 1 is lost in it, otherwise signal O. Thus, sequential combinations of signals from two sensors and 2 at the entrance to the room will be 00,10, I, 0I, 00, and at the exit ode - 00,01,11,10,00.

These signals from sensors 1 and 2 are fed to the inputs of the decoder 3 of their channel, which, depending on the state of the sensors, forms the following signals at their outputs: 00,11,10, 01.

The signals developed by the decoder 3 are fed to the inputs of the conversion unit 4 of its channel.

The first trigger 9 is set to I by the signal 10, provided that the fifth trigger 28 is in the single state, in about it it is set

In accordance with these conditions, the m-unit input of the trigger 27 is connected to the output of the element 25, one of whose inputs is given a signal 10, and the other is the zero output of the trigger 28, the zero input of the trigger 27 is connected to the output of the element 13, to one of the inputs of which are signaled 00, and on the other, the zero output of the trigger 10. Unit input of the trigger 28 is connected to the output of the AND element 26, one of the inputs of which is given a signal 01,

and on the other - zero output of the trigger 5 inserts trigger 27 into e, pynichnoe sos 27, zero input of the trigger 28 is connected to the code of element I 14, one of whose inputs has a signal 00, and the other - zero output of the trigger 9. Single trigger input 9 connection gg is not with the output of element 15, one of the inputs of which is given a signal 10, and the other - a single output of the trigger 28, zero input of the trigger 9 connection, With further movement of the object, i.e. at position 11 1 and 2, the zero state of the flip-flops 9 and 10 is confirmed. Then, at position 01 of the sensors 1 and 2, the flip-flop 10 is set to one, the flip-flop 27 remains in one, and the flip-flops 28 and 9 are in zero.

At position 00 of the sensors, when the moving object leaves the zone of action of the sensors, the trigger 23 through the elements 18 and 11 III-1 20 is set to one state, the triggers 27 and

It is not connected with the output of the RSHI element 21, to one of the inputs of which a signal 11 is given, and to the other - a signal from the output of the element 11. The single input of the trigger 10 is connected to the output of the element 16, to one of the inputs of which a signal is sent 01, and another single trigger output 27, the zero input of the trigger 10 is connected to the electrical output of the STI 22, one of the inputs of which have a signal 11, and the other a signal from the output of the element 12. The single input of the trigger 23 connects the inputs of which are spymed to vyho - Do element And 7, and the other - to the output element And 18. One of the inputs of the element And 17 connection en with a single output of trigger 9, and the other with a single output of trigger 28, the third is signaled to p. 00. One of the inputs of the element And 18 connects from one -: py: -5 output of trigger 10. the other from er. That is the trigger output 27, the third signal is 00. The bullet input of trip-ra 23 is connected with the output e. And 19, on one of the inputs of which a zero output of trigger 9 is applied::; a l; another - zero trigger 10, and the third signal is 00,

When moving a moving object in the zone of action of sensors 1 and 2, the trigger 9,10, 27 and 28 fix and

and trigger 23 serves for f1: xa- tion of the fact of full passage at entry or exit.

The sequence of work of the elementary enterprise of the four-unit block 4 of the pvi input is l,

next. Before the start of the input, the position of the sensors 1 and 2 00 and all the triggers are in the initial zero state. When a moving object overlaps sensor 1, which is located on the outside of the aisle, sensors 1 and 2 become at position 10, at one of the outputs of the diverter 3 of extraction II 1 and

That is, upon further movement of the object, i.e. at position 11 1 and 2, the zero state of the flip-flops 9 and 10 is confirmed. Then, at position 01 of the sensors 1 and 2, the flip-flop 10 is set to one, the flip-flop 27 remains in one, and the flip-flops 28 and 9 are in zero.

At position 00 of the sensors, when the moving object leaves the zone of action of the sensors, the trigger 23 through the elements 18 and 11 III-1 20 is set to one state, the triggers 27 and

10 remain in one state, triggers 28 and 9 remain in zero. After the flip-flop 23 is set to one, its level at the zero output and the input of the element OR-24 is connected with it. The O level is set. If at the same time, the remaining inputs of the OR-NOT 24 element associated with the recalculation blocks of the 4 remaining device channels also If levels are present, then level 1 appears at the output of the OR-NO 24 element. This level enters the input of the element 12, the other input of which is connected to the single output of the trigger 27 (level), while the output of the element 12 sets the level 1 (signal +) | which, acting through the element OR

And 1I, the other input of which is connected to the single output of the trigger 28 (level 1). At the same time, at the output of the element 11, a level (signal -) is established, which, entering through the element OR 21 at the zero input of the trigger 9, sets the latter to the zero state, after which the triggers 28 and 23 signal 00 also set to the zero state element and input element HJM-HE 24, associated with the zero output of the trigger 23, on-in, which leads to

is level 1,

5 appears to be a level O at the output of an OR-NOT 24 element and the output of an AI element.

Thus, at the output of the element I I1 of this conversion unit 4 22 to the zero input of the trigger 10, the signal 20 is formed. The signal - is formed, corresponds to the last zero output to the output through the pass, and then the trigger 27 and 23 sig. - the premises, and at the output of the element And 12 - cash-CO are also set to the nu + signal corresponding to the input.

the left state and at the input of the OR-NOT 24 element associated with the zero output of the trigger 23, level 1 appears, which results in the appearance of level O at the output of the OR-NOT 24 element and the output of the AND 12 element.

On exit, when sensors 1 and 2 become in position 01, trigger 28 is set to one. With further movement of the object, i.e. at position 11 of the sensors, the zero state of the flip-flops 9 and 10 is confirmed, the flip-flop 28 remains in the one state. With further advancement at position 10 of the sensors, the trigger 9 is set to one state, the trigger 28 remains in one state, the triggers 27 and 10 are in zero state. At position 00 of the sensors, when the moving object leaves the zone of action of the sensors, the trigger 23 through the elements AND 17 and OR 20 is set to one, the triggers 28 and 9 remain in one, and the triggers 27 and 10 are in zero. After the flip-flop 23 is set to one, at its zero output and the input of the OR-NOT 24 element associated with it, the level O is set. If there are levels at the inputs of the OR-NOT 24 element associated with the Scaling 4 of the other channels of the device, Oh, then at the output of the element I.PI –NE 24, level 1 appears. This level goes to the input ele

And 1I, the other input of which is connected to the single output of the trigger 28 (level 1). At the same time, at the output of the element 11, a level (signal -) is set, which, entering through the element OR 21 at the zero input of the trigger 9, sets the latter to the zero state, after which the triggers 28 and 23 signal 00 also set to the zero state element and input element HJM-HE 24, associated with the zero output of the trigger 23, on-in, which leads to

is level 1,

Signals + from all recalculated

25 blocks 4 are fed to the corresponding inputs of the element OR bis of its output - to the input of the direct account of the reversible counter 7 and the input of the counter 8. Signals - from all recalculated

30 blocks 4 are fed to the corresponding inputs of the element OR 5 and from its output - to the input of the countdown of the reversible counter 7.

The outputs of the elements OR NOT 24 all

The 25 counters 4 included in the device are connected to the corresponding inputs of the OR-NOT elements 24 counters 4 relating to other passages of the room to be monitored.

40 These links provide interlocking of the scaling units 4 of the device for the time of forming the signals + or - over any channel. So, if as a result of entering or

45 turns through one of the passes at the output of the corresponding counting unit 4 via wils signal + or - (trigger 23 in one state, at the output of the OR-NOT 24 element - level G, at the output of one of the elements 12 or 11 - level 1), the level 1 from the output of the ItTDi-HE 24 element of this scaling unit 4, entering the inputs of the elements OR-NOT 24 other scaling units, will prohibit the formation of signals + and - in them for the duration of the signal + triggered counting unit 4. If during this time buys -

If an entry or exit is made through some other passage, this fact is recorded on the trigger 23 of the conversion block 4 of this passage by setting it to one. After forming the signal + or - in the previously triggered, conversion unit 4, setting the trigger 23 of this conversion unit to the zero state and the output at the output of the OR-NOT 24 level O element associated with it will unlock the conversion unit 4, zanyannyh with the rest of the passages, and the signal + or - will be able to form at the output of the next in time response of the counting unit.

If the inputs / outputs are simultaneously completed through two or more passes, the device spontaneously sets to the state corresponding to the input or output through one of the passes (a + or - signal is generated at the output of one of the recalculated blocks 4). the triggered 23 of the respective scaling blocks 4. After completing the passage and resetting the elements of the scaling block 4 on which the + or - signal was first generated, the same signal will be generated in the same way ly and other conversion blocks associated with the aisles through which the inputs-outputs were made.

At the output of the elements 11 and 12 of the conversion blocks 4, the signals - or + appear only in the case of a full pass (output or input). Any changes in the direction or oscillations of a moving object in the zone of the sensors do not cause the appearance of spurious signals at the outputs of the respective conversion units 4. In addition, the entire sequence of movement of a moving object in case of incomplete passage is reflected only inside the conversion units 4 of each channel (trigger state 9 , 10,27,28 conversion unit), excluding, thus, the possibility of mutual influence of channels.

The duration of the signals + and - is always constant, depends only on the speed of the elements, the input of them to the conversion unit, and does not depend on any factors beyond the first.
