Description

Lredlaga.mye device relates to hommuti automation devices and can be used in the switching equipment of electrical engineering (those measurements).

There is an electronic co., Mmutator, containing sensors, the output of each of which is connected by iK to one, from the inputs of its own key, the OUTPUTS of which are combined with the field "iKO switches on the input of the encoder, and the shift register. Each of the .regist cells consists of the AND and the main trigger schemes, one and; from the inputs of which is connected to the corresponding .and inputs and main triggers of the other shift register cells. One of the outputs of the main trigger is connected to another input (Key, and the other output of the main trigger is connected to one of the inputs of the first circuit And the next one, ki shift register.

The proposed electronic switch differs from the well-known one in that a pre-trigger has been inserted into each cell of the shift register. And one of the inputs of the first circuit “And connected to the output of the second circuit“ And the previous cell with one of the inputs of the second circuit “And its own cell. Another input is a second swarm of the circuit “And is connected to one of the outputs of an additional trigger, d, the other output of which is connected to another input of the first circuit. "And, and. Exit the first scheme" And

connected to the second input of the main trigger .pu own. cells

This allows to increase the reliability of the device. Electronic switch, shown in the drawing.

It contains sensors D1-DZ, key.n К1-КЗ (channel), shift register I / -LAZ cells, main trigger T1, additional trigger T2, first and second circuits And and the one of the other devices of additional memory trigger. and the program controls the respective main triggers of the cell and the shift register, which serves to open one by one. In the event that the Lth sensor program is not transmitted to this program, then the additional L-number trits are recorded with a zero and the corresponding shift register cell is excluded from the operation, and the triggering nm-olls is not fed directly to the cell. V + 1, to the mine cell L. Thus, the channel key with the N dimension is always closed with this program.

The sensors are connected to the channel inputs. Opening the key and polling the sensor is done from the output of the main trigger of the corresponding temporary distributor cell, which is a register

Shift and. Can be assembled by any known: 110Y scheme.

All C & I: P | e equals are derived from the outputs of the respective additional triggers.

The program of the survey of sensors, miayetsl L1a triggers T2. And for definiteness, the presence of a unit, stored, on the strmer, in cell H1, trigger T2, ll rl, leads to the fact that the first circuit skips the trigger pulse on tr | Igger T1, and the second circuit does not skip pulses. If in this P | D1 program, the D1 sensor is not polled, the trigger T2 of the cell IL1 is in the position "zero, the cell circuit I / does not skip the impulses, the main trigger T1 of the cell I1 is reset, and to provide a cyclic; register shift the trigger pulse through the scheme and then through the scheme. and R2 it goes, to the input of the main traffic;

If B of the selected program should be onrash, and sensors D1, DZ, etc. (sensor D2 is not interrogated), then T2 cell triggers L1. And KAZ recorded units, and T2 cell trigger L2 is in the position of "zero. With this, the I1 cells and the IZ n I 2 cell circuits, the co; de | Ni “And 2 cells of the Ya 1 n IZI circuit and the} I cell of the I2 cell are closed, the main trigger of the I 2 cell is reset.

In the operation of the .im1p register: pulses from the output of the main trigger of the cell H1 through the I2 circuit of the H2 cell and the I1 circuit pass to the input of the four-axis axial trigger. When changing the program, the T2 triggers of all the cells are reset: Zero, and again, the program, m. Can be inputted by pulses or potentials, which are distributed to the program inputs.

PRIOR DIRECTORSHIP and

Electronic 1kom, a mutator containing sensors, the output of each of which is connected to one of its own inputs, the key, which are combined and connected to the input of the encoder, and the shift register, Each of whose cells consists of “And and the main trigger circuits”, one of the inputs which is connected to the corresponding inputs of the main triggers of the other shift register cells, one of the outputs of the main trigger. And is locked to another key input, and the other output of the main trigger is connected to

one of the inputs of the first circuit "And the next one, ki of the shift register, characterized in that, in order to increase the reliability of operation of the device, an additional trigger is inserted in each cell of the shift register; At one of the inputs of the first circuit “And connected to the output of the second circuit“ And the previous cell and with one of the inputs of the second circuit “AND its own cell; Another input of the second circuit “And” is connected to one of the outputs of the dololnitel trigger, the other output of which is connected to another input of the nervous circuit “And, and the output of the first circuit“ And is connected to the second input of the main Tpnrreipa of its own cell.
