Description

(54) DEVICE FOR THE CONTROL OF A TELEGRAPHIC TRACT

one

The invention relates to radio engineering and can be used to control the correctness of the operators' compliance with information exchange rules, as well as to control the load distribution. ..

A device for monitoring the telegraph path is known, containing a series-connected spurious start protection unit and a decoder, the first and second outputs of which are connected respectively to the first inputs of the address detector, the control detector and the input of the communication unit, the first output of which is connected to So

the registrar of service combinations 1.

However, the known device has insufficient accuracy krntrol.

The purpose of the invention is to improve the accuracy of control,

for this purpose, a time interval counter, an electronic clock, as well as a series distributor, a TaifTOB distributor, a memory block, a binary code into a telegraph converter, and a pulse shaper are entered into the device,

the output of which is connected to the input of the service combination recorder, while the third, fourth, sixth, sixth and seventh inputs of the decoder, as well as the outputs of the control detector and the address detector are connected to the input of the package distributor, combined with the first input of the memory unit, to the second and third whose inputs

0 are connected, respectively, to the outputs of the time interval counter and the electronic clocks, and to the input of the counter. time intervals the third output of the decoder is connected, the second output of the switching unit is connected to the second input of the address dettoperator, and the second output of the distributors of the parcels is connected to the second input of the binary to telegraphic converter.

0 9 memory, 10 binary code to telegraph converter, 11 e-loop driver, 12 service combination registrar and electronic clock 13. The device for monitoring the telegraph path works as follows. It is connected to the transmission path of the subscriber panel of the controlled end point. Block 1, which also coordinates the input of the device with the output of the subscriber panel i, forwards the passing signal to the input of the decoder 2. The latter decodes the information arriving at its input, and PEI, the presence of service combinations in it, the challenge, who is the telegram beginning sign (ZNT), the telegram end sign (CST) and the output on the outputs of the decoder 2, a signal appears that and the signal from the outputs of the detector 3 or the detector determines the addresses of the block 9, from which information is to be read, and simultaneously starts the distributor 7, which, in turn, controls the operation of the distributor 8 switching the readable bits of the selected cell, block 9 Thus, on the way out 9 block rows are formed in parallel to form a conditioned feature signal had come to the input performance combi nations which use the transducer 10 using the signals converted into the distributor 7 comfortable for registration and re cottages wire combination. These combinations are formed by the shaper 11 and transmitted to the receiving telegraph unit of the controlled end point, which is the recorder of 12, which means that the operator of the controlled end point is informed about the structure of the telegraphic message. If the operator makes gross errors, for example, a mustache: yzyz, three or more requests for autonomy, as well as for large transfers, which can lead to a decrease in the reliability of receiving Telegr # 1m, block 14, the signal is released. on a signal from block 9, it issues a retransmission to the transfer point, and the connection is resolved. The operator, having received information about the structure of the transmitted message, learns about the reason for the selection and has the ability to make a decision without excessive attempts to establish a connection of non-productive station equipment. . In addition, the proposed device makes it possible to obtain a monitoring protocol, by which the telegraph operational control service can assess the quality of the work of the terminal operator in terms of fulfilling the information exchange rules, and also analyze the time the operator performs various operations and the total occupancy time. For this in Formi. A conditional sign of service combinations introduces the time / elapsed information from the time of the call to the arrival of the combination. This cooperation is carried out by the counter 5, triggered by the output te signal, the call to the decoder 2, whose outputs are connected to the corresponding inputs of block 9. In the conditional indication of the operation call on the electronic clock 13, information about the current time is entered, which makes it possible to estimate the load intensity using the protocol telegraph path in time and direction.
