Description

The invention relates to instrumentation and can be used in measuring and computing equipment, automation, and telemechanics, as well as for multi-channel precision measurement systems of constant loads, for example e. d. ter.mopar

A switch is known, containing a pulse distributor, AND elements, a matrix switch, memory cells, a register, and a program input unit 1.

The well-known switch is characterized by a limited scope.

Most blnz, kim to the description of the invention of the technical nature of the invention is a switch containing a matrix switch Sculet, the first input of which is through the block of elements AND is connected to the output of the reversing distributor, the second input - to the output of the distributor, the control 2

In this switch, the modes of the monitored circuits along the diagonal of the matrix and the polling of the required channel are not possible, i.e. the commutator has a limited area of the name.

The purpose of the invention is to expand the field of application of the switch.

1Packed. The goal is achieved by the fact that pulse shapers and a logic block, the first

The input of which is connected to the output of the control unit on the input of the first pulse generator, the second input of the logic unit is connected to the output of the first pulse generator and the input of the second generator pulse, the output of which is connected to the third input of the log; 1 unit, the first output of the logic unit is connected to the reset unit On | Pr.i., vto.roy -, to the input of the distributor, the third - to one of the 13 inputs of the block of elements And, the fourth - to the input of the reversible distributor.

The drawing shows a block diagram of the proposed switch.

The switchboard contains the matrix switch /, the first input of which is connected through the block of elements And 1 to the output of the reversing distributor 3, the second input to the output of the distributor 4. The control unit 5 and the voltage reset unit 5, the drivers

0 pulses 7 n S and logical block I whose first input is connected to the output of control unit 5 and the input of the first driver of impulses 7. The second input of logical unit 9 is connected to the output of the nervous driver named after pulses 7 with the input of the second driver of impulses 8, the output of which connected to the third input of the logic unit 9. The first output of the logic unit 9 is connected to the voltage reset unit 6, the second to the input

The distribution server is located 4, the third is sent to one of the inputs of the battery unit 2, the fourth to the input of the reversible distribution 3.

The switch works with. In any way.

A prerequisite for the operation of the relay in the matrix switch is the presence of signals at the output of the distributor 4 and at the output of the element block 2. And any operating mode starts with resetting the polarized relays, the reset windings of which are located in the voltage resetting unit 6.

In the sequential polling of channels, the polarized relays are connected in the matrix neipe switch. ; In this case, the signal from the control unit 5 is over; the start of the impulse driver 7, the impulse from whose output through the logic unit 9 is fed to the input of the reset unit 1Gap, p 6, reset the polarized relays. At the same time, the signal from the control unit 5 through the logic unit 9 is fed to the input of the voltage relief unit 6, resetting the polarized relays. The signal from the output of the control unit 5 through the logic unit 9 is fed to the input of the distributors 3 and 4 and sets them to the state corresponding to polling the next relay of the matrix switch 1.

The back front of the output pulse of the first shaper 7 starts the second shaper of nmnulses 8, the pulse from the output of which through logical block 9 enters the input of the block of elements AND 2. The appearance of signals at the outputs of the distributor 4 and the block of elements And 2 causes the corresponding relay to trigger. When a next pulse appears at the control output unit 5 in a similar fashion, the next relay is activated.

Thanks to the appropriate connection of the control unit 5 through the logic unit 9, the modes of the op4 can be carried out at the inputs of the distributors 5 and 4 in the device

dew of monitored channels by columns. matrix, row m, diagonal nam and polling mode of a single channel.

The use of two pulse shapers and a logic block favorably distinguishes the proposed switch from the specified prototype, since it widens the range of application of the switch due to the possibility of additional modes of operation.
