Description

one

The invention relates to the field of automatic information processing and can be used, for example, for processing multi-channel time-pulse information recorded on a magnetic tape by an airplane flight recorder system.

The known devices for processing multi-channel time-pulse information, using a magnetic mite accumulator as a source of information, include a shaping unit, a block of distributing the pulses over the corresponding channels, an information converter into analog value, a multichannel recorder and a computing unit.

A disadvantage of the known devices is the impossibility of complete automatic processing of information without first digitizing it for input into the computing unit, as well as the lack of control over the accuracy of the information, which reduces the performance and quality of processing.

The purpose of the invention is to improve processing performance, to provide the ability to control the reliability of information and record errors.

The proposed device is characterized in that it additionally includes a tag block, a coding block and an analysis block, with the second, third and fourth outputs of the block.

the formations are connected to the inputs of the analysis unit, the label unit and the first input of the coding unit, respectively, the output of the label unit is connected to the second input of the coding unit, the third input of which is connected to the first output of the analysis unit, and the output is connected to the input of the computing unit zan with the second input of the multi-channel recorder.

0 The drawing shows a block diagram of the proposed device.

It contains the information source 1, a shaping unit 2, a pulse distribution unit 3, a conversion unit 4, a multi-channel recorder 5, an analysis unit 6, a tag unit 7, a coding unit 8, and a computing unit 9.

The device works as follows. A pulse system with time-pulse modulation from the source of information 1 is fed to a shaping unit 2, in which signals are amplified and generated, and frame pulses are generated in the intervals between information frames. Block

The 5 3 allocations convert time-pulse modulation to pulse-width modulation and distribute the signals through the appropriate channels. Conversion unit 4 converts information with pulse width modulation

0 to analog value. From the output of the conversion unit 4, information (no more than four selected channels) is output for recording in analog form and a multichannel recorder 5. From the generation unit 2, the pulse information in the natural sequence is fed to analysis unit 6, label unit 7 and coding unit 8. Analysis unit 6 reveals the presence of spurious signals or the omission of information pulses, counting the input signals in each frame of information, while the corresponding counters of the analysis unit 6 count the number of errors caused by signals or skips of information pulses. If the total number of errors exceeds a predetermined number, the analysis unit generates and transmits to the coding unit 8 a stop signal for entering information into the computing device. When each error is detected, the analysis unit generates a signal to record it, which is fed to one of the inputs of the multi-channel recorder 5. The tag unit 7, when there are no errors in the information, generates two main labels K and N, and the appearance of the tag K corresponds to the end the time interval of the last signal in the frame of the information channel signal, the time of the appearance of the label “H corresponds to the beginning of a new frame. If in one of the frames there are less signals than a known number of information channels, then the label "K is not generated; if additional signals appear in the frame, then additional labels will be generated for each of them. The main and additional tags, characterizing information reliability, are fed to coding block 8, which converts time-pulse information into parallel binary code and transmits it along with tags to computing block 9, while it is possible to transmit information of all or separately specified channels. The computational unit performs full processing of information, excluding frames with errors with the help of confidence marks, and also calculates and stores the number of errors that are periodically printed on digital printing (not shown in the diagram) for comparison with the number of errors recorded by the analysis unit. , which allows to evaluate the stability of the information channels.

Thus, the device allows proving complete automatic information processing at the same time of all or separately specified channels taking into account its reliability, which leads to an increase in productivity and an improvement in the quality of processing. The possibility of registering errors allows a preliminary assessment of the reliability of the initial information recorded on a magnetic medium before entering into the computing unit.
