Claims

The device contains a write register I, an input valve 2. an analyzer of matches of coC combinations 3, a read valve 4, a message recorder 5, a receipt receiving and generating unit 6, and a rewriting unit 7. The device operates as follows. In the initial state in the bits of the register of record 1, zeros constituting the zero initial combination are written, at the first output of the block of acceptance and the formation of a receipt "execution 6 is set to high potential, holding the input gate 2 in the kptiiTOM state, and at its second output - low the potential that locks the rewriting unit 7. The first code combination is fed to the first input of register 1 and to the second input of code combination matching analyzer 3. Simultaneously with the reception of the first code combination from the output of record 1 register zero The original code combination through the open valve of input 2 is fed to the first input of the analyzer of code combination matches 3 for bitwise comparison with the incoming first code combination. As a result, a comparison of the first code combination and the original, zero code combination at the output of the code combination matching analyzer 3 results in a signal "resolution arriving at the first input of the rewriting unit 7. The rewriting unit 7 stores the signal" resolution before the arrival of the command "execution." After the device receives the entire code combination with the arrival of the command "execution at the second output of the receiving unit and generating a receipt", execution 6 sets a high potential to the second input of the rewriting unit 7, and at its first output a low potential locking the input gate. At the output of the rewriting unit 7, a "census" signal is generated, which is fed to the control inputs of the read valve 4 and the write register 1. Thus, the first code combination is transferred to the message register 5 and stored in the write register. . Such a state of a device, when a code combination received on a given cycle is stored in the record register, the first potential output of the receiving and formation block of the receipt is a high potential, and the second output is low potential, is the initial receive the following code combination. The second code combination is fed to the first input of register 1 and to the second input of code combination matches analyzer 3. Simultaneously with the reception of the second code combination from the output of record register 1-first code combination, through the open input gate 2, goes to the first move of code combination matches analyzer 3 If the nerve and the second code combinations are different from each other, then with the arrival of the command, the use of the device is rotated according to the algorithm described above. If the first and second code combinations coincide in all bits (this indicates that a false repetition of the code combination received in the first cycle occurred), then the analyzer of the matching code 3 signal does not give a “resolution,” and with the arrival of the command “execution a the output of the rewriting unit 7, the signal "renicb is not generated. In this case, the second code combination to the message logger 5 is not translated and is stored in the record register 1. When receiving all subsequent code combinations, the device operates according to the algorithm described above. The device allows to reduce hardware costs and improve the reliability of information transmission systems. Apparatus of the Invention A device for eliminating errors of the type of "false repetitions in systems of transferring discrete information with feedback, containing a rewriting unit and serially connected register of the record, input valve, analyzer of matches of code combinations, and the output of the register of records through the read valve is connected to the input of the message recorder, And one of the outputs of the receiving unit and the formation of the receipt is connected to the control input to the input valve input, characterized in that, in order to simplify the device and ysheni reliability, to another input of the coincidence analyzer codewords is connected a first input of the register entries for the other two-input gate whose output is connected respectively schityva.ni and output rewriting unit, and the output matches analg1zatora codewords connected. to one of the inputs of the rewrite unit, to another input of which another output of the receiving and forming unit of the receipt is connected, execution, and the output of the rewriting unit is connected to the control input of the read valve.
