Description

The invention relates to computing and data processing technology.

Devices for inputting information are known, which contain blocks of reproduction, generation, selection of information, control and comparison, and a counter of channels 1.

However, such devices have low speed and limited functionality, they lack the ability to automatically monitor and diagnose. using a computer.

The closest to the invention to the technical essence is a device for processing and entering experimental data into computers, containing 6, iioK forming of computer words, the output of which is connected to the first output of the device, the interface unit with a computer, the output of which is connected to the second input / device , the control unit, the first output of which is connected to the first inputs of the computer word formation unit and the interface unit with a computer, the channel selection unit, the first output of which is connected to the second input

and the second output is with the first input of the control unit, the time code allocation unit, the LABLED output of which is connected to the third input of the computer word shaping unit, and the second output is connected to the second input of the control unit, the data rarefaction unit, the output of which is connected to the third entrance

10 of the control unit, and the matching and switching unit, the input of which is connected to the input of the device, the first output to the inputs of the data rarefaction unit, channel selection and allocation

15 time codes, and the second output - to the fourth, the input of the block forming the machine words 2

This device is characterized by a large load on the input channel of information in the computer, since the experimental data have significant redundancy, as well as the inability to monitor and diagnose from the computer.

The purpose of the invention is to increase the reliability of the data transmitted in the computer.

The goal is achieved by the introduction of redundancy redundancy, block;

mode, the control unit and the register, 1 the first and second inputs of the redundancy reduction block are connected to the second output of the control unit and to the second output of the matching and switching unit, respectively, the output of the redundancy block connected to the second input of the block; the first, second and third outputs of the mode setting block are connected respectively to the first input of the control unit, the second input of the channel selector unit, the fourth input of the control unit, the second input of the control unit is connected to the register output, the third input of the control unit is connected to the first output of the channel selector unit , the first output of the control unit is to the fifth input of the control unit, the second output of the control unit is connected to the control input of the matching and switching unit, the inputs of the mode setting unit are control inputs of the device properties.

The drawing shows a block diagram of the device.

The device contains a matching and switching unit 1 connected to the first input 2 of the device, a channel selection unit 3, a data dilution unit 4, a time code allocating unit 5, a redundancy reducer b, a control block 7, a switching and blocking unit 8 connected to the second input 9 of the device, the unit 10 of forming the machine words, the unit 11 of the interface, the unit 12 of the control and the register 13, the blocks 10 and 11 being connected respectively to the front 14 and the second 15 outputs of the device.

At the input 2 of the device receives digital signals from the source type of a multi-channel magnetic recorder or analog-to-digital Converter (not shown). This signals, via the matching and switching unit 1, arrive at the inputs of the blocks, select channels 3, dilute data 4, allocate time code 5 and reduce redundancy 6.

Unit 3 selects the number of service information from the flow of melon. Depending on the signal being set using block 8 of switching and blocking, block 3 solves the question of whether this channel is to be entered into a computer or not, and issues a signal to this in block 7 of the control unit.

The composition of the input parameters is set by the computer through the second input 9 of the device.

If the service information of the channel number is to be entered, then block 3 outputs it to block 10 of the formation of machine words. The data rarefaction unit 4 makes it possible to decide the question of entering a reference based on the characteristics that it reveals in the data stream supplied to its input. Block 4 can b.Pokrovirovat. VBO.P data on the signal from block 8 by sending a signal to block 7 control,

Block 5 extracts the time service information and sends it to the 10 d / w output unit in the computer. In addition, depending on the time code, block 5 may pause the entry of information by applying the appropriate signal to control block 7.

The block b analyzes the data for redundancy and, in the case of a positive result, sends the inhibiting sequence to the block 11, which exchanges the necessary signals for the input,

B.Pok 7 implemented. It does not sync all devices.

In block 12 of the control, the number of parameters entered in one frame is compared with the setting on the rep; string 13 code. In the event of a mismatch from block 12, a signal is sent to block 7, which forms a sign of frame failure in block 10. The magic words formed in block 10 are podgsts via the first output 14 of the device in the computer. The input of words is controlled by block 11 using the second output 15 of the device ..,

Using the computer unit 8, it sets the monitoring modes of the data input device, by supplying the control signal from the unit 8 to the control unit 7.

In this mode. The AV.M with the help of block 8 sets the control digital signals which, through the block 12 of the control, pass into the block 1 of matching and switching.

The proposed device reduces the time for monitoring the data input channel and its diagnostics, as well as the amount of required memory, which according to preliminary data shortens 5 to 10 times while simultaneously increasing the speed of the input channel.
