Description

lines of call pulses, switch 23 of the teleoperation type, linear receiving unit (code telephormatics) 24, pulse distributor (teleinformation signals) 25, register (code teleinformation) 26, decoder (code teleinformation of coarse reference) 27i, decoder (code teleinforma exact count) 272 , register (binary-decimal codes) 28, digital indicator (telemetry) 29, block 30 of separation filters, block 31 of emergency telealarm, block 32 of indication of accidents on objects, switch 33 of conversational circuits, block 34 of the light indicator katsii unit 35 hands-free simplex communication switch 36 sorts the communication tower phone 37 automatic telephone exchange system (PBX), a local control room telephone 38 and the battery block 39 of analog gauges.

A call center 40 includes a pulse dispenser 41, a continuous telecontrol unit 42, an alarm remote signaling unit 43, a coded sensor (coarse readout) 44i and a coded sensor (accurate readout) 442.

The executive unit includes a call block 45, a distributor 46 pulses, a telecontrol unit 47, a telecontrol unit 48, an alarm unit 49, a coded sensor (coarse readout) 50i and a coder of (exact readout) 502 The proposed device operates in the following way.

The device is controlled completely with the help of block 2 of setting and executing commands. Power is supplied by a voltage of 220 V with a frequency of 50 Hz. The power supply unit 1 is turned on by a corresponding toggle switch of the power unit 2 and produces a plurality of constant and variable voltages for powering all the components of the device.

The number of the object to be selected is dialed by the digital input block 17 with the control buttons. The object number, consisting of three digits of the octal system, is recorded in register 7 in binary form. Information about the number of the object to be selected is sent to the mimic biv block 14 of central printing.

Depending on which digit was dialed first in register 7, the appropriate feeder is selected by a block of 20 linear feeders and lightning gaps, which is connected to the control device switch 21 and disconnected from the separation filter unit 30. The electrical parameters of the selected feeder can be measured using the control device 16, which allows the control of the mains supply voltage.

The second digit of the object number is the selected combination of call signal lines. Depending on the value of the second

digits of the number by the call pulse line formation unit 22 is selected a definite structure of the paths of all working pulses to specific lines of the selected feeder through switch 21. When the third digit of the object number is selected, the defined combination of polarities of the three call pulses is selected by the call pulse polarity forming unit 8. After the full dialing of the number of the selected object by block 2, the block 3 of the clock pulses for selecting an object, which produces four clock pulses, is started. In the first cycle, the first trigger pulse is sent with an increased amplitude and the second pulse, the polarities of which were determined by block 3, and the direction by block 22. Simultaneous sending of two call pulses is possible

because in all cases they are sent on different wires (for example, if the first pulse is sent on the first line, then the second one is on the second wire, and vice versa). During the second beat, a pause is created, and

low voltage pulses are sent to the communication line.

During the third cycle, a third call pulse is sent, the polarity of which is periodically changed to the opposite of the polarity of the signals by block 5.

In the fourth cycle, the switch 22 is connected to the switch 23 of the kind of teleoperations, the output signals from which are always passed over the free wire in the presence of the third

call pulse, i.e. if the line of the third

the pulse is the first wire, then the output

switch 23 is connected to the second

wire through block 22.

When establishing a telephone connection after

Subscriber selection to block 22, through switch 23, a conversation circuit switch 33 is connected, through which alternating voltage is sent to power the subscriber call. When the subscriber removes the handset during its call, the switch 33 connects the selected feeder to the type of communication switch via block 22. The selected feeder can be connected to the dispatcher telephone 38 of the local battery system or in the simplex 35 unit 35, or the telephone line of the PBX, if the dispatching telephone 37 of the PBX system is in operating condition. In the standby state, all feeders are connected to separation filter unit 30, which passes signals of 300-3500 Hz to speakerphone unit 35, and signals over 6 kHz to block 31.

If there is an accident on the object, the corresponding resonant relay of the block 31 is triggered, and on Bv ets the alarm signal light in the display unit 32. Telemetry and other teleconnections are performed by starting the sync pulse shaping unit 11 after the object is selected by block 3.

A linear receiving unit 24 of a code telecommunication information is connected to the switch 23 when receiving the code telecommunication information.

Signs of the code information produced by the linear unit 24 are recorded in the corresponding bits of the register 26 of the code teleinformation through the corresponding circuits of the pulse distributor 25. After receiving two bits of binary information, unit II generates a shift signal for the unit 5 that controls the pulse distributor of the selected controlled point (executive paragraph) and the pulse distributor 25. The received code information is supplied to block 34 and to decoders 27i, 272, which convert the original code teleinformation are issued in intermediate binary code. The decrypted information in the form of three incomplete tetrads is recorded by the register 28, from which the information in decimal form enters the digital indicator 29 and in binary-decimal form in the digit printing block 14 and on other external devices.

The control of command execution is performed by the command execution stop unit 12, with which it is possible to program the command execution delay after receiving a command of acknowledgment signals, after telemetry, when sending telecontrol signals or during continuous telecontrol. If there are no stop commands, the dispatch panel adjusts to a multiple telemetry mode, in which the received information can last for up to 2 minutes, after which it is periodically updated. The telecontrol is carried out after telemetry by the telecontrol command generation unit 18, which prepares direct current signals of different polarity depending on the control command. In the absence of a telecontrol, the subsequent clock after the telemetry is idle.

In continuous telemetry, instead of the linear receiving unit 24, the linear receiving unit 9 is connected to the communication line, which generates signals of a change in the telemetry value for the teleinformation processing unit 10 during continuous monitoring.

When connecting objects with analog sensors (frequency or time-pulse), the switch 23 of the type of teleoperations allows you to connect analog gauges in block 39 to the lines of the selected feeder via the control panel. The accuracy of telemetry with analog devices depends on the class of instruments and the parameters of the communication channel, which will vary in a wide range depending on the change in distance

between the controlled point (executive point) and the control center,

In the control room half-set, it is possible to connect a coding) time sensor 13 for the digital-printing unit 14 and the external processing-processing and external information unit 15 (TTY, computer, etc.).

In order to selectively call an object in each half-set of a controlled item (execution point), a block is used.

40 (45) calls, containing three nodes for receiving three selective call pulses.

After selecting the desired controlled point, the object is polled, sending polling pulses over a free wire of the communication line. With this, the shift of the distributor

41 (46) pulses are performed by changing the polarity of the voltage of its supply.

The pulse distributor 41 (46) has eight internal states. In its first state, acknowledgment signals are transmitted, which are used as subaddress attributes. On the second, the first two are transmitted.

bit of a teleinformation code, on the third - the third and fourth bits of the code, on the fourth - the fifth and sixth, on the fifth - the seventh and eighth, on the sixth - the ninth and the tenth. The telecontrol signals are sent on the seventh clock cycle, and on the eighth clock the object state signals are transmitted or continuously monitored.

The combination of code sensors 44; and 442 (50i and 502) is a code converter, performed on the encoding

the rotation angle in the ten-thirds composite

combinatorial code.

Some code combinations are coarse.

readings can only have a two-digit meaning on the border of the transition of an exact reference from the minimum to the maximum value or vice versa. This partial elimination of read uncertainty is achieved by the fact that

The entire range of the exact reference is encoded by two coarse code combinations, one of which is generated at the boundary of the junction and overlaps an area of ± 25% of the exact reference range, the second coarse code combination can appear only in the absence of reading uncertainty.

The control room is compounded by the following measurement code:

in a way.

If the coarse code combination belongs to the zone of no read uncertainty, then the value of the higher bits unambiguously corresponds to the value of the coarse count, regardless of the readings of the exact count. In this case, the total telemetry value is equal to the sum of two readings.

If the coarse reference code combination belongs to the transition boundary zone (minimum maximum) of the exact reference, then the value

The coarse readout is equal to a smaller value if the exact readout value lies in the region of 50-100% of the exact readout range, that is, in the second half, and to a larger value if the exact readout value lies in the region of the exact readout range. At the same time, the total telemetry value is also equal to the sum of two readings.
