Description

The device for generating and transmitting digital information contains a generator I of control signals, control unit 2, sampling unit 3, first and second switching units 4, first and second normalizer switches 5, first and second comparators 6, reference signals unit 7, synchronization unit 8 and control, analyzer 9, indicator 10.

The device works as follows.

According to the control signal generated by the synchronization and control unit 8, the generator 1 of the driving signals outputs a control code to the control unit 2 with a structure close to the real transmitted information. Control unit 2 converts the control code from generator 1 in the same way as information transmitted through control unit 2 under actual operating conditions. The control code converted by the control unit 2 enters the sampling unit 3, which groups it according to a certain law, in accordance with the digital information processing algorithm laid down in the synchronization and control unit 8 and the analyzer 9. The control information grouped in such a way by the sampling unit 3 is fed via two parallel streams to the switching units 4, to the control inputs of which a signal is transmitted from the analyzer 9 to enable the transmission of the control information. Further, the processing of control information is carried out independently for each of the channels. The passed 4-switching unit -control information is transmitted to the information inputs of the switch-normalizer 5, the control inputs of which receive impulses from the synchronization and control unit 8. According to the program embedded in it, the control code is converted, which is already in the normalized structure arrives at the information input of the comparator 6 of this penalty. The 8 C block, synchronization and control, according to a pre-selected control code processing program, writes the reference signal block 7 control code for each of the monitored parameters: From the output of block 7, the code of the Reference Signals in a strictly defined sequence accesses the second input of each of the comparators 6. Comparator 6 pr “v9dit sra Examination of a normalized:., control code with a code of reference signals of monitored parameters. At the output of the instruments 6, a code is generated for evading the normalized control, code for the reference signals. KodB1 uklo neni. for each of the channels come to the analyzer 9, which, according to a certain algorithm, progresses their analysis.

In the case of the left-hand dodge codes for each of the channels, the analyzer 9 generates a signal about the normal operation of the control unit 2 and the device as a whole. When the evasion code is different from zero, but identical for each of the channels, the analyzer 9, processing its wire in accordance with the selected algorithm, generates a signal about the presence of a specific fault in the control unit 2.

In the case of different avoidance codes for each of the channels, the analyzer 9 processes these codes first to ensure that each channel is operational. Having determined which of the channels the malfunction has occurred, the analyzer 9 with its control signal conducts, through the switching unit 4, switching off the faulty channel and continues processing another channel. AT

If it works, an analysis is made of the code for avoiding possible malfunction in the control unit 2. The results of the tests carried out in the analyzer 9 are transmitted via a communication channel on

indicator 10, which records information about the health of the .block 2 cont. roll and device in general.

Use in the device for generating and transmitting digital information

processing mode of the control code for each of the channels allowed to increase the reliability of the transmitted information, which is confirmed by the positive results of the docking tests of the prototypes.
