Description

eleven

The invention relates to the field of telecommunications and can be used in automated unrailing systems.

The purpose of the invention is to increase the amount of information transmitted.

The drawing shows a structural electrical circuit of the data transmission device.

The device contains l / information blocks 1, block 2 controls consisting of l / blocks 3 transmissions, l / blocks 4 receiving receipts, l / blocks 5 receiving information, l /, switches 6, / V first registers 7, l / the second registers 8, S triggers 9, l / elements OR 10, L / decoders 11, block 12 seals and the third register 13.

The information transfer device operates as follows.

The input of the Tpetbero register 13 of the block 2 receives the control command code, and the second inputs of the l / flip-flops 9 receive a control signal from the second control input of the block 2. The triggers 9 are then set to state 1, allowing the control command code from the third register 13 to pass through the fJ switches 6 to the inputs of the corresponding blocks 3. Through the blocks 3, the control command code is transmitted to the addresses of all information blocks 1 via data transmission channels.

Information blocks 1 generate acknowledgment signals indicating the execution of the command, and issue information in accordance with the command codes. Acknowledgment signals and information from information blocks 1 are fed to the corresponding inputs of block 2.

Unit 2 receives the acknowledgment codes through the corresponding blocks 4, from whose outputs they arrive at the inputs of the corresponding first registers 7, which are intended for the operational storage of the acknowledgment codes. x signals. From the outputs of the first re132

Histrop 7 Acknowledgment codes are fed to the inputs of the decoder 11, which verify the conformity of the acknowledgment codes to true signals. When the corresponding outputs of the decoders 11 match, the control signals appear through the OR 10 elements to the first inputs of the trigger 9. The latter are set to prohibit the control command from passing through the corresponding switches 6 (to the addresses of those information blocks 1, which correctly received the control command code and confirmed that the control command was received (by sending an acknowledgment code). Thus, o6pa3ONf, the transfer of the control command code to the information addresses Units 1 will automatically continue until all (or the required number) information blocks 1 receive a control command code and confirm that a control command code has been received. If all the information blocks 1 need to be involved in solving the problem facing the system , the system operator can stop sending the command code of the control command to the addresses by supplying the control signal via the third control input of unit 2 to the second inputs of the elements OR 10. At the same time, all the triggers 9 are set to O and the transmission to yes control command in the address is stopped. For the convenience of the system operator, it is advisable to indicate the status of all the flip-flops 9 on the indicators.

Information: Ion codes from information blocks 1 through blocks 5 are fed to the inputs of the respective second registers 8, which are intended for operative storage of information codes. From the outputs of the second registers 8, the information codes are sent to the corresponding inputs of block 12, which is Topbrfi for temporary compaction of codes through the information output of block 2.
