(B) POWER SUPPLY DEVICE WITH TACT PULSES

one

The invention relates to automation and telemechanics and can be used in information transmission systems.

According to the main auth. And, it is known a power supply device with clock pulses of telemechanics systems, containing a clock pulse formulator, connected to two circuits from series-connected power windings of ferrite elements and to one end of common wire, negative element, memory element, display element and control unit with windings power supply and output winding the beginning of the first power winding of the control unit. connected to the power winding output of the last ferrite element of one circuit, the end of the second power winding of the control unit soleno- 20 dyn en with the output of the power winding of the last ferrite element of another circuit, the end of the first and the beginning of the second winding of the power supply of the TELECOMANIKY subsystem control unit

Connected to the other end of the common wire, the output winding of the control unit is connected via a series-connected negative element and an element to the input of the display element} 1},

However, the device does not allow for a quick search of the failed unit in the telemechanics system after a failure is detected, which leads to a significant recovery time and, therefore, simply telemechanics systems.

The purpose of the invention is to increase reliability by reducing the recovery time of the remote control system / by reducing the search time for the failed unit.

This goal is achieved by the fact that the prohibition element is introduced into the power supply device by clock pulses. t second memory element, second display element, button, switch, second output. Winding and reset bus, the first output of the second winding is connected via a button to the first input of the Ban element, the second output; - to the second input of the element. The prohibition, the output of the prohibition element is connected to the first inputs of the second memory element, the second input of which is connected to the reset bus, the output of the second memory element is connected to the input of the second display element, the power windings of each ferrite element are connected via a switch common wire.

If the first ferrite element is a pulse generator, then the second output winding is introduced into it and it is advisable to design this element into a. driver of clock pulses, and the winding to output to the connector of the driver. If at the beginning of the chains of motion, there is no generator of pulses, then it must be inserted and placed in the former.

The drawing shows a power supply device with clock pulses of telemechanics systems.

The device consists of a generator of 1 clock pulses, two circuits 2 and 3 clock motions, representing a series connection of the windings 5 5 | respectively, the power of ferrite elements located in the telemechanics system and common wire 6,

; The device has a control unit 7 with windings 8 and 9 of the power supply and the first output winding 10, the registration unit 11 consisting of the negative element 12, the memory element 13, the indicator I, New device elements - the second output winding 15 introduced into the first ferrite element .ment (with windings k and S power), the element of the ban 16, the second element 17 of the memory, the second indicator 18, the switch 19 to two circuits and the button 20,

The second output winding 15 is connected via button 20 to the enable input of the Ban 16, the second element 17 of the memory of the second indicator 18, connected in series; both circuits at the output of each telemechanic system are connected via switch 19 to the common wire 6,

The device works as follows,.

In the event of a failure (open circuit or short circuit / in the movement circuit of one of the telemechanical system units, the H indicator lights up, indicating that the power supply device is in a failed state. To determine the unit in which the failure occurred, you must turn on the button 20 , which corresponds to the search mode. The switch 19 from the neutral position is reversed to position 1, connecting the outputs of the circuits of the driver of the clock pulse generator with the common wire. If the circuits of the movement of the unit 1 are intact, the windings 5 and the first power of the ferrite element included in the beginning circuits motion obtekayuts clock, resulting in the output winding 15 is will be pulses every 20 ms, which are applied to the enabling input element prohibition causing its activation, and then

the output of the second memory element to the second fault indicator. If the indicator 18 is on and does not go out after pressing the Reset button, this indicates that the movement chains of the block under test are operational. Then switch 19 is moved to position 2,

If, as a result of checking this block, indicator 18 is on, this indicates that the movement of the second block being tested is in good order. Similar operations are repeated for all n blocks. If, when checking one of the blocks, the malfunction indicator remains extinguished, this indicates that a failure has occurred in the chain of motion of this block. The faulty black is replaced, after which the button is turned to the open state, the switch is set to the neutral position, as. search mode is over.

The application of the proposed solution makes it possible to significantly shorten the search time of a faulty block after detecting a failure, which

reduces the recovery time of the remote control system.
