Description

The invention relates to telemechanics and is intended for remote control of a two-position object.

The aim of the invention is to simplify and increase the reliability of the device.

The drawing shows a diagram of the device.

The device contains at the control point the first diode 1, the closing switch 2, the opening switch 3, the closing contact 4 of the blocking relay 5, the second diode 6, the capacitor 7, the gas discharge lamp 8, the resistor 9, the first wire 10 of the communication line, the second wire 11 of the communication line, at the control facility, the power source 12, the first diode 13, the intermediate relay 14, the capacitor 15, the second diode 16 and the closing contact 17 of the intermediate relay.

The device works as follows.

In the initial position, all relays are disconnected and at the control point the gas discharge lamp 8 from one half-wave of the alternating voltage of power supply 12 is lit: the output of power supply 12, first wire 10 of the communication line, disconnecting switch 3, gas discharge lamp 8, resistor 9 , the second wire 11 of the communication line, the coil 14 of the intermediate relay, the first diode 13, the output of the power supply 12. The lamp signals the readiness of the object to turn on and the health of the communication line.

When the closing key 2 is closed from the half-wave current, which is set by diode 1 through diode 13, intermediate relay 14 is triggered. At the same time, the closing contact 17 of the intermediate relay closes, connecting the source output through diode 16 to the second wire 11 of the communication line, the half-wave of the current source 12, the polarity of which is determined by the diode 16, trips the blocking relay

5 at the control point, (through the diode

6 and the opening key 3), its closure-. by pressing the shunt contact 4 on the lock key 2. At this point, the activation process is over. After passing the command to turn on the lamp 8 continues to burn from one half-wave, set by diode 16 along the circuit: the second output of the source 12 pit

neither, the diode 16, the closing contact 17, the second wire 11 of the communication line, the resistor 9, the lamp 8, the opening key 3, the first wire 10 of the communication line, the first output of the power supply 12.

The resistance of the resistor 9 is incomparably large compared to the resistance of the coil, 14 intermediate relay, therefore the illumination of the lamp B is almost independent of the presence or absence of additional resistance of the coil 14 in the turn-on circuit of the lamp 8. Disconnect the device using the disconnecting key 3. Capacitors 7 and 15 included parallel to the coils of the blocking relay 5 and the intermediate relay 14, it is possible to operate this relay in a stable manner on a pulsating voltage.

When disconnected, in the event of any failure of one of the relays, the other is necessarily disconnected, since the blocking and intermediate relays are powered through the contacts of each other.

Sequential switching on of the power supply with the elements of the object and control point allows it to be installed at the control point or at the communication line.

The use of the proposed device will significantly save the number of veins in the control circuits, which is important with a large distance between the point and the control object.

The presence of a signaling the state of the line reduces the time spent on repairs.
