The invention refers to the aptomatic and P1,1 numeral techniques and can be used to enter information from the systems 1 1 processing of the current W (form of the personnel structure.

The aim of the invention is to expand the field of application of the device by providing various modes of selection of information.

FIG. 1 shows a functional diagram of the device; in fig. 2 - an example of the design of the amplifier.

The device for inputting information contains a block 1 amplified, a counter decoder 3, a first block of 4 switches, a first element II 5, a block of 6 AND elements, a second block of 7 switches, a switch of 8 operating modes, a second element of AND 9, a first element OR 10, block 11 drivers, one-shot 12, the second element of the IPI 13, trigger ep 14, information inputs 15 and outputs 16 of the device, the request output and the reset input of the device 17, amplifiers 18-21 of block 1, trigger 22, element 23 and the counter 24 included in meter 2.

Pa figs. 2, the amplifier 25 is indicated by a threshold element 2f, a front driver 27, a discharge driver 28.

The device works as follows.

At the input 15 of the device receives a stream of data frame structure.

The frame structure of the early is a sequence of multichannel signals, including parallel binary code of the meter, signals (inputs 1p ... Ex) with the synchronization of each code by the clock signal TCCp), and the entire frame - by the clock signal (CBS p) ,, incoming

simultaneously with the code of the first

body signal, i.e. the first data channel of the entire information frame. The number of channels in the frame is 64, and the dimension of the binary code of the measuring signals is 8 bits.

Input SIGNZHYY with an amplitude of 1.5-2.0 mV from the input 15 enters the block where amplified by the amplifier 25 and formed using elements 26-28 in the form of square signals, then enter the blocks 11, 22 and 23 of the device.

operation of the device: the mode of exclusive data input of the frame structure I1P1 rs-press group data entry m М1гпж (combination of channels to the core.

It should be noted that in the combination of channel numbers, the data from which are | selected and sent to the outputs 16 in the group input mode, there must be data from the first channel, which also contains the KCC synchronization signal, which is necessary for proper decompression of frames received information connected to the outputs of the 16 receiving device.

In the mode of exclusive input of data by the log, 1 and O signals from the switch of 8 operating modes, the signals from the first key 4 are transmitted to the OR 10 element. And the And 5 element output receives a signal corresponding to the number selected by the unit, 4 channels in the entire frame channel sequence. The counter 24 starts counting the TCC clock signals when the flip-flop 22 is set to one, which is triggered by the KCC signal received at the beginning of the frame, Decrypted by the decoder 3, the signal about the last channel number in the frame resets the counter 24 and flip-flop 22 to the zero state,

In the group data entry mode, the signals from the switch of 8 operating modes permit the passage of signals through the AND 9 element and prohibit the AND 5 through the element. In the second block 7, using the toggle dialing, the following channels are set: decoded by the decoder 3 and passed through block 6 of the outputs of counter 24 from the first to the last channel numbers through the toggle switches 7, depending on the combination of channel numbers entered in block 7, are sent to the OR 13 element, the OR 13 output is present sequentially one after another or some gaps that are lagging one behind the other are selected. e are the channel numbers of the frame that allow the signals corresponding in time to the presence of information of the selected channel at the output of the block of 11 drivers.

and starting the one-shot 12, sig} 1al from which it is delayed enough to record information in block 11, after which the trigger 14 is set to one, which informs the receiving device about the need to enter information from the outputs 16. Upon completion of the input, the receiving device sends input 17 is the signal of the end of the input, which resets the trigger 1A.

Thus, the proposed device allows the selection of information channels, i.e. enter information from one channel or from a given group of channels of the frame. The selection of the selection modes and the installation of channel numbers is carried out using switches.
