Abstract

The invention relates to devices for capturing the occurrence of new information in the control room and station code decentrals. The purpose of the invention is reliability. The device contains encoders 1, transmitter 2, switch 3, trigger 4, the outputs of which and the reset inputs are connected to block 5 for determining the start of transfer. The outputs of the clock distribution 6 are connected to the inputs of the switch 3. When transmitting information from a linear point, the clock distributor 6 forms the temporary positions of the address and information parts of the signal. The address part of the signal through the switch enters the transmitter. The information part of the signal through the switch enters the selected encoder 1, where, in accordance with the contact position of the control relays, a serial code is formed, which is fed to the input of the transmitter 2, 1, or so on. about S yu s - e 4ik

I

The device operates as follows. When transmitting information from a linear point, the clock distributor 6 forms the time positions of the address and information parts of the signal. The address part of the signal through the switch 3, where the linepicker address of the point is formed, enters the transmitter 2, the information part of the signal through the coder 3 enters the lateral whiftors 1, where, in accordance with the position of the contacts of the control relays, a serial code is formed which is fed to the input of the transmitter 2.

In the case of absence, the transmission of information from the linear point, the generator 14 produces pulses that are fed to the input 27 of the additional distributor 13 and the matching unit 9. The appearance of a signal at the output of the additional distributor 13 determines the connection sequentially.

The detuning ensemble encoder t is a digital inverter 7, a sort of analogue analogue block 10, a comparator II, the corresponding block 12 compares to the triggers 4. The definition of new information in encoder I is performed cyclically, with the time of determination of the triggers 4. one block of sources of information T, equal to the time of the following pulses of the generator 14,

When the distributor 13 enters the first position and the output of block 9, a pulse equal in duration to 1/2 T is formed (which enters the second B1 SOD of the encoder 1, and d, then through the corresponding closed rear contacts of the control and relay analogue relay, to the second inputs of the D / A converter 7 From the output of the digital-to-analog converter 7, an ana-jloroBbm signal, which corresponds to the code combination of the information source block, goes to the first input of the comparator 11. At the same time, from the output of block 9 matching, the i & inyjibe control is inputted to d block 10 where information schitshaets .On the third input of the comparator 11. To determine the reliability of po- vytseni new information generated short

a pulse of the output of block 9, which is fed to the input of comparator AND, which reveals the difference between the current and previous values of the states of the encoder 1, information about which was stored in the analog memory of block 10. In case between the definitions of the new information in the danny unit of information sources there is a change, then at the output of comparator 1 a signal t is generated, the pulse of which arrives at the second inputs of the coincidence unit 12, at the first input of which r; o. the signal I already exists from the output of the distributor 13, through Slrk 12 coincidence, the signal 1 is fed to the installation input to state 1 of the trigger 4, which detects the state change in the encoder I and transmits the signal IS From the output of block 9, a signal is sent to the encoder I and to the element SHKI-NOT 8, as well as from the analog recording unit 10. Thus, the current signal from the output of the analog digital converter 7 is recorded in the analogue storage unit 10. After a short pulse, the analog pulse s ApoNamy unit Yu goes into the state of information storage, at the output of the element OR NOT 8 there is a potential that prohibits the operation of the digital analog converter 7. At the arrival of the next generator pulse 14, the predecessor 13 moves to the next position for determining the presence of changes in the state of the next encoder 1; and so on.

In the event that a trigger detects a change in the source of information, block 5, determining the start of transmission, supplies a locking signal to the blocking input of generator 4, and only after complete T1 transfer of information from this encoder to the corresponding1; The output of block 5 for determining the start of transmission appears a signal that sets the trigger in and out: the ho dr state, and also the blocking potential is removed from the blocking input of the generator 14.
