Description

I:.) D) Reteiie refers to temporary telecom technology and telecommunications and can be used in telemetry systems.

The purpose of the invention is to increase the information content of the device.

Figure 1 shows the structural diagram of the proposed device; FIG. 2 is a functional circuit of the code converter.

The device contains information inputs 1, control input 2, the first - the third (last) processing levels 3-5, on the first - the second (last) processing levels - code converters 6, pulse shaper 7, elements OR 8 and information channels 9, each of which is performed on the first 10 and second 1 1 elements AND and the element OR 12, on the third (last) processing level — the first code converter 13, KPI elements 14, pulse generator 15, the second code converter 16 and information channels 7, each of which is made on the element minute AND 18 and OR element 19, encoders 20 - 23 and outlets 24 of the device.

The code converter contains elements AND 25 - 27, element OR 28, triggers 29 and shapers of 30 pulses.

The device operates as follows.

Consider the operation of the device with

three processing levels. In the initial state, on the informational 1 and controllable 2 inputs of the device (Fig.), Zero signals are set, the trigger 29 of the converters 6.13 and code 16 are in the zero state, at the outputs of the elements OR 28 of the converters 6.13 and 16 codes, the zero signal is present (FIG. 2). For example, let the inputs 1,, 1, 1 j: ,, and 1 t of the device receive single signals. These single signals will go through the corresponding elements OR 12 channels 9 ,, 91 and 9 ,, of the first level 3 processing, elements OR 12 channels 9 ,, 9, | and the second level 4 processing, the elements OR 19 channels 17 and 17 of the third (last) level processing-) and arrive at the information inputs of the converter 16 code. In the converter 16 of the code (FIG. 2), the single signals through the respective rovers of 30 pulses ycr iOBs-rt to the single state trigger 29, and

29j. Single signals from, 1x outputs of the flip-flops 29 go to the peg, the inputs of the corresponding elements of And 26, and 2b2. and the corresponding inputs of the element Sh1I 28, and zero signals from the top outputs - to the first inputs of the elements And 27, and 27. A single signal from the output of the element OR 28 will pass through the open element And 26, and from the output of the converter 16 code will go to the input of the encoder 23 and the first inputs of elements And 18 canapes 17, on the second inputs of which there are already single signals. From the outputs of the elements And 18, single signals arrive at the first inputs of the elements And 11 channels 9 and 9 of the second processing level and through the elements OR 14, and 14 - to the corresponding drivers of 30 pulses, which are installed by the triggers 29, U-29 converters of the 13 code into one condition. The operation of the two-bit code converter 13 is similar to the operation of the code 16 converter described above. Single signals appear only at the outputs of the element And 26, and the element OR 28 of the converter 13 code. At the outputs 24 of the encoder 22, a binary code appears corresponding to the liTQi element number 12 of the channel 9 level 4 processing. Since the drivers 7 and 15 form a single pulse only on the falling edge of the single signals from the first outputs of the converters 6 and 3 of the code, the state of the flip-flops 29 of the code converter 36 does not change. A single signal from the output of the element AND 26 of the converter 3 code passes through the open elements AND 11 and 10 of the channel 9 level 4 processing and the element OR 8 and with the help of the imaging unit 30 sets the trigger 29, the converter 6 of the code to the single state. At the output of the element AND 29 i converter 6 of the code, the processing level 4 is given a single signal, which is converted into a binary code of the element number OR 12 of channel 9, processing level 3, i.e. In the code of the first group of information inputs 1 - 1. The same single signal from the output of converter 6 of the level code .4 processing will trigger element 11 of channel 9, processing level 3, the single signal from the output of which will poll the

A single signal is output only at the output of the element I 26, the transducer 6 of the code and using the encoder 20 is converted into a binary code corresponding to the first input 1 with a single signal. In this way, . the outputs 24 will be generated binary code corresponding to the most priority signals.

After the first pulse arrives at the control input 2 of the device, in the converter 6 of the level 3 code processing, this pulse passes through the element 25 and sets the trigger 29 to the zero state. At the output of the element 265 the converter 6 of the code receives a single signal, the outputs of the encoder 20 change the code, reflecting the state of the device's input G .; and at the outputs of the 24 remaining encoders 21-23, the code signals remain unchanged.

After the second pulse arrives at control input 2, trigger 29j of converter 6 of level processing code 3 will go to zero state, and driver 7 will receive a pulse formed on the falling edge of a single signal of converter of level 6, which will go to the input of converter 6 of code level 4 processing, set it to its original state. In this case, the shaper 7 of the processing level 4 pulses is triggered, the trigger 29 is switched, the code converter 13 is in the zero state. At the output of the AND element 262 of the code converter 13, a single signal is obtained according to which changes, respectively, at the outputs 24 of the encoder 22, a code signal. A single signal from the output of the converter 13 code enters the inputs of the elements And 11 channels 9 2 and 9 level 4 processing, opening the inputs of the elements And 10 and 10. Since the second input element And 10 even before received a single signal, this signal will pass through the element GITI 8 /) on the information input of the converter 6 code and will lead to change

Unity 1 1 The 1 signal from the output of the element 27 of the converter 6 code with the help of the element 11 of the channel 9 and the processing level 9 interrogates the state of the elements of the channel 10.

15, the control input 2 of the device, the converter 6 of the level 3 code of processing will transfer to the initial state and through the shaper 7 will transfer the converter of the 6 level code 4. to the initial state, which, in turn, through the shaper 7 will set to the initial state 13 th transducer transducer. Yes. On the back f of the pulse from the first output of the converter of the 13th code, the forcing device of 15 pulses will work, which will reset trigger 29, the converter of the 16th code and thereby cause the appearance of a single signal at the output of 30 De element AND 26.i of the 16th code converter. The encoder 23 converts this signal into a binary code entering the outputs 24 of the device. The process of encoding a single signal

the device that is fed to the input occurs in the same order as described above, then (with the arrival of the next pulse to the control input 2 of the device) the converters 16,13 and

Q 16 codes are reset if the signals at the information inputs 1 of the device do not change.

Thus, the proposed device performs priority coding by groups at each processing level.
