Description

1 The invention relates to communication technology and can be used in cable linear paths of digital transmission systems. It is known a device, a telecontrol containing a test signal generator and a level indicator at a serviced regeneration point (PFU), and a sequentially connected regenerator, a filter and an amplifier connected via a telecontrol line to the level indicator, the regenerator input is connected to the unattended regeneration point (NRP) the output of the test signal generator over the link .1J. The disadvantages of the known device are the implementation of remote control only when transmitting a special test signal, i.e. during interruptions of communication, as well as the low accuracy of estimating the reliability of transmission of a separate regenerator, since the Test signal, which has oscillations of a constant component, passes to the control regenerator through all previous regenerators. In addition, the device consumes considerable power from a remote source power supply due to the amplifier being constantly turned on. The closest to the proposed technical essence and the achieved result is a teleservice system for linear regenerators of digital transmission systems, containing a remote power source, a control command sensor and an indicator at a serviced generation point, and a sequentially connected regenerator and an error detector, counter at an unattended regeneration point. error, receiving the nickname of control commands, the arrival of which through the telecontrol line is connected to the first output of the control command sensor, Then, the remote power receiver and the second remote power receiver are included in the remote power supply circuit, the second output of the first remote power receiver is connected to the supply inputs of the regenerator and the control command receiver, the second output of the second remote power receiver is connected to the power inputs of the error detector and counters errors 2. 434 The disadvantage of this device is the considerable power consumption of the remote power supply due to the fact that the error detector and the error counter are constantly connected to the remote power supply unit with their power inputs. The purpose of the invention is to reduce the power consumption of remote power.

The drawing shows a structural electrical diagram of a tele-monitoring system for linear regenerators of digital transmission systems.

The teleservice system for linear regenerators of digital transmission systems contains an ODP 1 source 2 remote power supply, an indicator 3, a blocking element A, a delay unit 5, a control command sensor 6, an OPC 7 regenerator 8, an electronic switch 9, a signal indicator 10, first 11 and second 12 remote power receivers, memory block 13, delay block 14, pulse generator 15, error detector 16, element OR 17, control command receiver 18, reset pulse shaper 19, error counter 20. PIU 1 and IUU 7 are interconnected by lines; information, remote power and remote control line 21.

The system works as follows.

In the operating mode, the electronic key 9 shunts the second 12 remote power receiver, as a result of which the power supply of the detector 16. errors, signal indicator 10, pulse generator 15, OR element 17 and error counter 20 is not produced. This achieves a reduction in remote power supply per unit of teleservice-pzan-i.

In the verification mode of verifying the transmission of reliability, the sensor of commands of evacuation b on the ODP 1 generates a signal for polling the required NRP 7. This signal receives the control command receiver 18 and generates a pulse arriving at memory 13. The latter is set to the state corresponding to the opening of the electronic cluster.

9. In this case, a second 12 remote power receiver is turned on in the remote power supply circuit, and the power supply voltage for 5 ToiJ detects 16 errors, a signal indicator 10, a pulse generator 15, an OR element 17, and a counter 20 errors. Since the supply voltage is not established immediately, but after approximately 1 s

o The 16 error detector and the 20 error counter in this MOfieHT are not in operating mode and cannot provide the required measurement accuracy. Therefore, in ODP 1, simultaneously with the interrogation command, the control command sensor 6 generates an enable signal for indicator 3, which, via delay unit 5, is fed to the control input of lock element 4, and the subsequent SRI begins to pass signals passing through the remote control line 21 to the indicator input 3. The delay time of the release signal is selected with a somewhat longer setting time.

5 nominal supply voltage of the 16 error detector and 20 error counter. In addition, the signal from the output of the memory block 13 through the delay block 14, ensuring the same time

0 delay, is applied to the reset pulse shaper 19. The latter forms a .11pulse, which sets the counter of 20 errors to the zero state after the voltage of the power supply reaches the required value. As a result, the device is ready. to measure real particular errors,

No signal at the output of the regenerator 8 detector 16 errors

0 (due to its operation algorithm) does not detect. In this case, the signal indicator 10 turns on the pulse generator 15. The sequence of pulses from the generator 15 and 5 pulses through the element OR 17 enters the counter 20 errors, simulating the stream of errors, which is recorded by the indicator 3 on the ORP.1. After the end of the measurement session, the sensor 6 commands

0 control in the ODP 1 forms a command coming through the bridge. 21 tele-. control to the input of the receiver 18 control commands, which puts the memory unit 13 in the state corresponding to the closure of the electronic switch 9, which bypasses the second 12 remote power receiver, and the power voltage from the detector 16

errors, the sipgala indicator 10, the pulse generator 15, the element OR 17 and c4et4HKa 20 errors of this IUU 7 is removed. Also, via the telecontrol line 21, the disabled units are switched off using the electronic key 9.

The application of the proposed system makes it possible to reduce the power of remote power consumed by the NRP by 1.5 times, as well as to detect a regenerator in the linear path in which, for some reason, there is no output signal.
