 The drawing shows a diagram of a device for transmitting and displaying information about the train situation.

 In cabinet 1 of the central post of private supervisory control of each control circle there is an input of a clock pulse receiver 2 and the outputs of frequency receivers 3. The output of a clock pulse receiver 2 is connected to the input of the control unit 4 of the universal shift register 5. The outputs of the frequency receivers 3 are connected to the parallel inputs of the universal shift register 5. The first output 6 of the control unit 4 is connected to the control input of the parallel recording 7 of the universal shift register 5, and the second output 8 of the control unit 4 is connected to the control input sequential shift 9 of the universal shift register 5. The output 10 of the universal shift register 5 is connected to one of the inputs 11 of the telegraph channel 12, the output of the clock receiver 2 is connected to the other input 13 of the telegraph channel 12.

 The receiver 14 of the single control center comprises a control unit 15 of a random access memory, random access memory (RAM) 16 and a display device including a shift register for inter-cycle information storage 17 and a mnemonic display 18. The output 19 of the telegraph channel 12 is connected to the information input 20 of the RAM 16 receiver 14. Output 21 of telegraph channel 12 is connected to input 22 of control unit 15, output 23 of which is connected to address input 24 of RAM 16. Output 25 of RAM 16 is connected to information input 26 of shift register 17 m zhtsiklovogo storage. The output 27 of the control unit 15 is connected to the input 28 of the synchronization of information recording in the shift register 17 inter-cycle information storage. The outputs of the bits of the shifting register of inter-cycle information storage, respectively, 29 and 30 are connected to electronic keys 31, including the LEDs 32 of the mnemonic display of a single control center, displaying the train situation. A device made in a combination of a cabinet of the central office of ChDK with a universal shift register, a telegraph channel and a single control center receiver containing RAM, sequentially shifting the inter-cycle information storage register and electronic keys that turn on and off the LEDs of the mnemonic display of the single control center, has novelty and meets the criterion "significant differences."

 The device operates as follows.

 Information for transmission to a single control center is generated at the outputs of receivers 3 of cabinet 1 of the central post of ChDK, reflecting the state of the controlled objects at the block sites and stations interrogated by the clock generator.

 From the output of the clock pulse receiver 2, a clock pulse is cyclically applied to the control unit, where the front of this pulse is delayed in time and then fed to the input 7 of the parallel recording of register 5. The status of the outputs of the frequency receivers 3 is recorded in register 5. At the time of the decline of the same pulse form the next control pulse and feed it to the input 9 of the register 5, allowing sequential reading of the recorded information.

 From the output of register 10, information in the form of a start-stop packet is fed to the input 11 of the telegraph channel 12, and from the output of the 19 telegraph channel, the information is fed to the information input 20 of the RAM 16 of the receiver of the single control center 14. Clock pulses of the CDC system are fed to the input of the 13 telegraph channel , from the output 21 of which the clock pulses are fed to the input 22 of the control unit 15, the output of which 23 is fed to the address input 24 and write information to the RAM 16 synchronously transmit the start-stop packet.

 Thus, information is transmitted and recorded in RAM 16 at the command of each clock cycle until the end of the transmission cycle. At the end of the transmission cycle at the command of the installation pulse, the control unit 15 puts the RAM 16 into read mode and generates pulses at the outputs 23 and 27 of the control unit 15 with a repetition period equal to 100 kHz. In this case, the read information is recorded in the register 17.

 The information recorded in the register 17 is stored in it until the next installation pulse and is displayed on the mnemonic display 18 using the LEDs 32 included in the load of the transistors 31 controlled by the outputs 29.30 of the register 17.
