Description

The invention relates to automation and computer technology and can be used to enter and evaluate multidimensional measurement information recorded by means of multi-channel magnetic recorders.

The aim of the invention is to expand the functionality of the device by speeding up the search, selection and evaluation of information entered from the registration means.

Haha. 1 shows a block diagram of the proposed device: in FIG. 2 is a timing diagram of the operation of the device.

The device comprises a first switching unit 1, a first 2 and a second 3 shapers. a pairing unit 4, a channel selection unit 5, a control unit 6, a first digital-to-analog converter (DAC) 7, a buffer register 8, a second DAC 9, a first trigger 10, a third driver 11, a second trigger 12, a comparison element 13, a second switching unit 14, the first 15 and second 16 groups of inputs, information outputs 17 of the device, additional outputs 18, input 19 of the reset device.

Block 5 channel selection contains a counter 20, a decoder 21, the element And 22, the first 23, the second. 24 and third 25 switches.

The device operates as follows.

The first group of 15 inputs of the device receives information from the means of reading data from magnetic tape (ML), and the second group of inputs 16 receives information from the converting devices of digital magnetic recording (DTM) complexes. The information of each of the group of inputs has the same structure, i.e. consists of sequential multi-bit code words - parameters (timing diagram 3), equipped with a clock (first) and frame (second) clock signals (timing diagram 2). The second, i.e. the frame clock located, like all bits, on the allocated bus, comes only with the parameter code of the first measuring channel in the set of codes of the multi-channel input information stream, which in this case has a frame structure of multi-parameter input data.

One of the toggle switches of control unit 6 provides logic levels 0/1 to the first switching unit 1 and, accordingly, information from inputs 15 or 16 depending on the use of the device with data coming from the ML of DTM means or with data coming from the converting means of DEM. enters the interface unit, in the register of which it is entered by the clock clock signal generated by the second driver 3 (timing diagram 7), generated from the first clock signal parameter accompanying each code and, accordingly, the information from inputs 15 and 16 goes to the device output buses 17. The same information is fed to the information inputs of the first DAC 7 and the buffer register 8. In the first DAC 7, it is entered for each first clock signal, i.e. at the output of the first DAC 7 (timing diagram 4) an analog signal will be generated that characterizes the state of the measurement parameters of all channels of the input data information frame.

At the output of block 8 and, accordingly, at the output of the second DAC 9, an analog signal will appear corresponding to the measuring parameter of only one channel of the information frame, the number of which is selected by channel selection block 5, i.e. the clock input of the buffer register 8 receives a signal from element 14 22 (timing diagram 9), corresponding to that three-position channel number in the frame, in the unit, decimal and hundredth positions of which the first 23, second 24 and third 25 switches are set, respectively, to the inputs of which single, decimal, and hundredths of the state of the counter 20 decrypted by the decoder 21, which counts all the first clock signals in accordance with the structure of the information frame, which is determined by the first a sync signal (timing diagram 5), which sets the counter 20 to its initial (zero) state. Since the first of the first clock signals of the frame is input to the device simultaneously with the second clock signal, for stable operation of the counter 20 by the shaper 11, a pulse is generated from the first clock signal, which is fed to the counting input of the counter 20 (timing diagram 8).

The second toggle switch of control unit 6 sets the logic levels O'7'Ί for the second switching unit 14, which controls two switching elements, the inputs of which are connected to the outputs of the first 7 and second 9 DACs, respectively, and the inputs are connected and direct one of the analog signals received from the outputs of blocks 7 or 9, to the comparison element 11, 'where during the signal matching the reference level an output signal is generated (timing diagrams 16 and 12), which sets the trigger 12 to a single state, which is via an additional output bus e 18 is supplied for input into the channel used for the analysis of multi-parameter measurement data on the electromagnetic compatibility of electronic components of the computer, through which the computer can switch to the corresponding operation algorithm.

Upon completion of the installation in the corresponding frame in the single state of the trigger 12, the signal from the computer from the input 19 will set the trigger 12 to zero and, thereby, prepare the device for the next cycle of entering information about electromagnetic compatibility in the computer. With the same signal from input 19, when inputting each content from output T7, through which the computer receives data on the contents of all measuring channels, where information about the electromagnetic compatibility of electronic means is recorded, and data on the contents of the channel, where the value of the reference signal is located, is set to zero, and trigger 10 is prepared for the next input cycle.

Thus, due to the introduction of new elements and corresponding connections, the functionality of the device is expanded. ''
