Description

one

The invention relates to a technique for transmitting discrete information, can be used in devices for the rapid assessment of the state of communication channels.

A device for operational

control of communication channels, containing an error counter, which is connected by one input to the sensor of statistical reset pulses, and the other through the analyzer of received pulses and the input unit to the receiving part of the communication channel. The received pulse analyzer marks incorrectly received symbols that are accumulated by the error counter, periodically reset to the zero state by a signal from the static reset pulse sensor til.

However, in connection with the grouping of errors in real communication channels, this device often gives false decisions about the unsuitability of the communication channel.

Closest to the proposed device for the operational control of communication channels, containing a serially connected input block, an error analyzer, a key and an error counter, to another input of which a time key entry is connected, to another input of which a first sample counter input and an output of a pulse sensor are connected reset as well as a display unit. The specified device gives an estimate of the channel is faulty only after two samples in which the number of errors exceeds the threshold value: a delay of 2 is made between the first and second samples.

However, the accuracy of monitoring communication channels with variable error grouping is low in this device.

The purpose of the invention is to improve the accuracy of control of communication channels.

time marks 5 ,. The following samples of the 13j samples are connected to the switching unit: analysis time 15 and the second time of the day-connection of pulses 7 of the statistical reset, count of samples o, switching threshold of the readiness factor 16 connecting to the input of the display unit 8, didn’t, but, the country didn’s statistical reset pulses 7 and through the control unit 10 - the input of the input unit 1 and the first reset input 11, to the other input of which the second output of the error analyzer 2 is connected, and the output of the reset key 11 through connected to its third input, to the second inputs of the controlled sample counter 13, the time of the statistical reset pulses 7 and to the third input of the display unit 8.

The proposed device works as follows

In the initial state, the control unit 10 with the help of the input unit 1 maintains the device in the off state, and the test sequence from the monitored communication channel to the input bus does not reach the error analyzer 2. In the display unit 8, the result of the previous measurement session is saved ,

Before starting the measurement, the input unit 1 is connected by a signal from the corresponding output of the control unit 10 to the monitored communication channel. At the same time, the reset key 11 is opened. The test signal is fed through the input unit 1 to the error analyzer 2 and to the synchronization signal generator 9, which ensures synchronous operation of the transmitter, its sensor, test signals and the receiving (reference) sensor located in the error analyzer 2.

At the moment of reaching a common phase, an impulse appears at the additional output of the error analyzer 2, which passes through the open reset key 11 and sets the error counter 4, the time stamping key 5, the controlled sampling counter 13, the selector counter ( 6, the pulse sensor 7 and the display unit 8. As a result, the counters are in the zero state, the time stamp key 5 is opened, and the evaluation of the previous measurement session is reset in the block 8. The pulse sensor 7 starts simultaneously, and the reset key 11 ryvaets by local reset circuit and starts anapiz link quality. error analyzer 2 detects incorrectly received symbols (error) and delivers them to upravp 1Oi

shichy input "caustic 3, the second input of which receives the auxiliary impulses often t-bi, formed by the nepai Sj r.G block: .Sia 1 2 connected to the pulse .rpp; ::; g ", e. Rator e 9. As a result, kgauch 3 transmits 4 4 1 & taps to the input of the error counter, the number of which is proportional to the number of errors. If, during the sampling time, the error counter 4 counts the number of errors greater than the threshold value specified by the switching unit 14, under its effect, the signal is closed by the BP-5 flag. After the next sample has been exhausted with the first output of the IMCH-LT SOB 7 sensor, it is set to the E error counter 4, which is: 3 7: -accordingly:: d: -: -: - Е -: е. o gkzo ;; B ::: food 1 out of, and, g; "

If for B e -; - ;; A 5-point counter, a sample counter 13 and a sample counter 6 are copied to unlicensed selections: 1 that supports a given {threshold / detection factor ratio, is defined by the switching unit 16, an impulse that is remembered in the display unit, which is displayed in the display unit, which is reflected in the display unit 16, which is remembered by the display unit 16, which is stored in the display unit. After this, at the end of the measurement cycle, the display unit 8 under operation - and; - the sensor from the second output of the yy-ray sensor :. gives out

After oxoH4a; 25i kajpo: during the measurement cycle of the measurement cycle, E is updated in the display field 8s and then the process is repeated.
