The invention relates to a pulse technique, can be used in automation devices.

The purpose of the invention is to simplify the proposed counter.

FIG. 1 shows an electrical binary diagram in FIG. 2 - time diagrams of his work.

The binary counter contains a remote switch that controls the reverse 1 and the bit cells 2, each of which has the first 3 and second 4 inputs, the first 5 and the second 6 outputs. The cell discharge consists of the first 7 and second 8 remote switches and contains a reversal circuit on the contacts 9 of the remote switch, the code information output unit 10 on the contacts of the first contact group of the switch 7 and the code output 11. In each bit cell the closing and opening contacts of the contact group 12 remote switches 8 are connected respectively to the opening and closing windings of the remote switch 7, and measles - to the switch of the contact group of the remote switch, with mlad- boiling it in the discharge cell 2 measles contact group 12 is connected to the first bus 13 the pulsed power. The opening and closing contacts of the second contact group 14 of the remote switch 7 are connected to the opening and closing windings of the remote switch 8-j respectively, to the second power supply bar 15. The closing and disconnecting contacts of the 9 contact group of the remote switch are connected

respectively to the first 3 and second 4 inputs of the bit cell. The end and breaker windings of the remote switch are connected respectively to the first 5 and second 6 output of the discharge cell. Outputs 5 and 6 of each previous bit cell are connected via inter-bit circuit to inputs 3 and 4, respectively, of the next bit cell. The second ends of the windings of the remote switches 7 and 8 are connected to a common li12

and 14 remote switch 7 is closed with make contacts. Code output 11 is set to code 001. Then the first

to the unit bus 18, and the switching contact to the code output 11.

On the timeline SFig. 2) denotes the impulse to turn on the direct PS count, the impulse to turn on the reverse counting PC, the signals on the common and second bus pulses T1 and T2, respectively. The indices O and P denote the intervals when the opening and closing contacts of the remote switches 7 and 8 in the corresponding bit cells are closed.

The device works as follows.

In the initial position, the contacts of all remote switches are in the position shown in Fig., Which corresponds to the operation of the remote switch from the PS pulse and all remote switches 7 and 8 along the breaking coil.

There is a code 000 on code yields, and the reverse circuit ensures that the meter operates in the direct counting mode. In this case, a change in the state of the remote switch 7 of the next bit cell can be made only by switching the remote switch 7 of the previous bit cell along the breaking coil, which corresponds to transfer (addition) 1 to the next bit cell. The transfer signal changes the state of the code output of the bit cell to the opposite, and a sequence of increasing binary codes is formed at code outputs 11, for example, 000, 001, 010, 011, 0a, etc.

The first pulse T1 from the strip 13 is supplied through a switching contact, closed with the opening contact of the contact group 12 of the remote switch 8, to the closing winding of the remote switch 7 of the first discharge cell, with the result that the switching contacts of the corresponding contact groups 10

and 14 remote switch 7 is closed with make contacts. Code output 11 is set to code 001. Then the first

55 impulse T2 from the bus 15 post is transmitted through the closing contact of the contact group 14 of the remote switch 7 to the closing winding of the remote switch 8 of the first

the discharge, as a result of which the switching contact of the contact group 12 of the remote switch 8 is closed with its closing contact. In the remaining bit cells, the pulsed power is supplied to the disconnecting windings, and the state of the disconnecting switch 9 does not change.

The second impulse T1 from the strip 13 comes through the closing contact of the contact group 12 of the remote switch 8 to the disconnecting winding of the remote switch 7 of the first discharge, with the result that the switching contacts of the contact groups 10 and 14 and the remote switch 7 return to their original position. When this occurs, the transfer signal to the next bit.

The remote switch 7 of the second bit cell is triggered by the closing winding, and the contact groups 10 and 14 close their closing contacts. At code outputs 11, code 010 is set. Then the second pulse T2 triggers the remote switch 8 of the first bit cell along the disconnecting winding, and the remote switch 8 of the second bit checks across the closing winding. In the third bit cell, the pulse power from the bus 15 is fed to the disconnecting winding and the state of the remote switch 8 do not change.

Upon receipt of the following pulses T1 and T2, the counter operation in the direct counting mode proceeds similarly.

To transfer the counter to reverse counting (subtracting) mode, the impulse PC is given a pulse winding on the remote switch, causing the measles of all the reverse circuits to close with their own closing contacts. In this case, such a counter operation is ensured, in which the change in the state of the next discharge cell can be performed only by switching the remote switch 7 of the previous discharge cell along the closing winding, which corresponds to borrowing (subtraction).

The loan signal switches the remote switch 7, i.e. changes the state of the bit cell to the opposite, and a sequence is formed at the code outputs

descending binary codes, for example 100, 011, 010, 001,000. Assume that the PC pulse arrived after the counter counted four pulses, and code 100 is present at the code outputs.

The first pulse T1 from the bus 13 is fed through the opening contact of the contact group I2 of the remote switch 8 to the closing winding of the remote switch 7 of the first discharge cell, with the result that the measles of the contact groups 10 and 14 of the remote switch 7 are closed with their own closing contacts. When the signal is received, a signal is taken from the second bit cell, to which the pulsed power is supplied.

Switch 7 triggers over the closing winding, and groups 10 and 14 close with their closing contacts. In addition, a loan signal from the third bit is generated.

The remote switch 7 of the third bit cell is triggered by the disconnecting coil, and the contact groups 10 and 14 are closed with their make contacts. The code O is set on the code outputs. Thus, subtraction 1 occurred from the contents of the counter. Then, the first pulse T2 triggers the remote switch 8 to the first and second discharge cell in the closing winding, and the remote switch 8 to the third discharge cell in the opening winding.

When the next pulses T1 and T2 arrive, the work in the reverse mode proceeds in a similar way.
