code signals, the second inputs of which are connected to the first and second outputs of the memory block 11, and the outputs through the element 17 are connected to the first input of the decoder 10 code signals, the second input of which is connected to the output of the shift register

13, and the outputs of the signal receiver 22 are connected to the inputs of the registers 13 and

14. The output of the shift register 14 is connected to the information input of the memory block 8.

The device works as follows.

When the train is moving along the receiving track, code signals are received at the locomotive in accordance with the indications of traveling lights. Transmitters 1 and 2 of code signals are hard-tuned, respectively, on each ty path. Switching on the transmitters 1J, 2 and 3 of the code signals is carried out from the corresponding signal relays of the block 6 signal relays of the traveling traffic light, and depending on the route of movement, the transmitter 3 is switched on via element 4. In addition, the track transmitters are set in the direction of travel from block 9 set the code signals. This setting, through the element OR 5, defines additional features of the signals for transmitters 1-3. The codes are transmitted using two-way relative-phase modulation, allowing two channels with code signals each to be received at the output of receiver 22.

These signals accumulate in shear; registers 13 and 14, and in register 13 informational parcels are contained, and register 14 contains additional features. The count of mmo of registers 13 and 14 on each clock of the information signal is compared by blocks 15 and 16 of the comparison of code signals with the contents of memory block 11, the signals at the outputs of which are determined by the selection of corresponding addresses. This selection is made with the aid of a counter 20 operating from a reference signal generator 19, in addition, arrays of such addresses determine the signals from the memory block 12 and the signal from the code signal selector 21. With the allowed signals on these inputs, the 1st brute force content is provided;

There are 11 memory blocks at the allowed addresses.

Reception of QOL signals.

An additional signal feature prevents the reception of other additional signal features, for example, from the track section, in this case, when the train is moving from the side uchi, when before that it received Q, QOL with another additional signal

you can do it with de mi da da ka sd ge poo sd to no i only one after that

the sign automatically switches to the red light of the locomotive traffic light, since among the allowed signals of the output of the memory block 11 for the comparison block 16 there is no signal with the allowed additional sign. When moving along permissive signals, when any code other than UK is present, the output of comparison unit 16 contains signals of all additional allowed features from memory block 7, therefore, movement along the switch section is possible. Similarly, but irrespective of the signal, there is a prohibition on receiving information of a different direction of movement until the corresponding switching of the track, 9 and locomotive 21 back-end blocks and allowed marker features. Such protection is most effective when feeding the supply end of one path to the relay end of another when on opposite routes.
