Abstract

The invention relates to automation and telemechanics and can be used to control two-way mechanisms. The purpose of the invention is to increase the functional reliability of the device. When the communication line is closed on diodes of different polarities, a permanent potential appears on the output of the L C filter connected to the communication line, which opens the key that closes the communication line to the diode of the same polarity. This turns on the generator of the displaced audio voltage. This signal through the isolating transformer, receiver and element U is fed to the input of the actuator. The closure of the communication line removes the voltage from the outputs of the L C filter, turns off the generator and the actuator. 1 il.

The drawing shows a functional diagram of the proposed device. The device contains a source of 1 voltage, a decoupling transformer 2, a receiver 3, elements I 5, executive elements 6 and 7, a continuous switching unit 8, a storage capacitor 9, an LC filter 10, indication units 11, oscillator 13, pinout element 14, LC filter 15, rectifying diodes 16-21, keys 22 and 23, movable control 24, which consists of (| Iltra 25, locking buttons 26 and 27), soft diodes 28 and 29, block 30 of the indication, the switch 31 and through the movable contacts 32 and 33, the remote control 24 is connected to the wires 34 and 35 of the communication line, and the terminal 36 is grounded laziness.

The device works as follows.

When switching on the alternating voltage from source 1, the keys 22 and 23 are locked, the voltage on the capacitors of the LC filters

10 and 15 are absent, actuators 6 and 7 are turned off, the LEDs of the blocks

11 and 12 displays are off. Checking the health of the communication line is carried out by closing it to the diodes 28 and 29 through the button 27. A brief luminescence of the LEDs of the display units 11, 12 and 30, as well as the audible alarm of the unit 8, indicate the health of the device. If it is necessary to turn on one of the actuating elements of the communication line, it closes, for example, on diode 28. At the same time, a constant voltage with a negative potential on its upper face occurs on the capacitor LC of filter 15.

relative to the bottom. Negative voltage) Phenomena passes through diode 16 and opens key 22, which closes the communication line to diode 18 even after releasing button 27. Constant voltage on LC-filter capacitor 15 through display unit 12 is fed to generator input 13 which forms an alternating voltage of sonic and supersonic frequency through the isolation link 14 into the line. This voltage through the isolation transformer 2 is fed to the input of receiver 3. The rectified voltage from the output of receiver 3 is fed to the inputs of elements And 4 and 5, and the negative voltage of the capacitor of the LC filter 10 is fed only to the first input of And 4 , which first includes the actuating element 6, and after 8 s-reversing switching unit 8, which drives the electric drive. When the lines are closed through limit switches or when the button 26 is briefly pressed, the capacitors of all LC filters are discharged, key 22 is locked and generator 13 is turned off. Executive element 4 is turned off and block 8 stops the drive.

In a similar way, the actuating element 7 is turned on when the diode 29 is closed, when the movement of the electric drive occurs in the opposite direction.
