Устройство дл ввода информации относитс к вычислительной технике и может быть применено в автомати .зированных системах управлени обработки данных.A device for entering information is related to computing and can be used in automated data processing control systems.

Известно устройство дл ввода информации ,в которое, с целью повышени надежности работы, введена схема блокировки многократной записи , один вход которой подключен к выходу, сдвигового регистра, второй - к входу матрицы, котора последовательно соединена с регистром адреса, запомииак щим устройством, регистром числа и блоком фиксации положени клавиш 1.A device for inputting information is known in which, in order to increase the reliability of operation, a scheme for blocking multiple recordings is introduced, one input of which is connected to the output of the shift register, the second to the input of the matrix, which is sequentially connected to the address register, storage device, number register and a key position fixing unit 1.

Недостатком указанного устройства вл етс невысока скорость ввода информации в вычислительное устройство .The disadvantage of this device is the low speed of entering information into the computing device.

Наиболее близким к предлгигаемому вл етс устройство дл ввода информации , в котором матрица через блок выбора строки и блок выбора столбца соединена с шифратором, выход которого подключен к сздвиговому регистру, соедиие ому с блоком выдачи команд, один вход которого св зан с регистром чисел, подключенным к-цифровому табло и номеронабирателю , а другой вход - с адресными кнопками, выход которых подключен к табло адресаC2J,Closest to the proposed one is an information input device, in which the matrix is connected to an encoder through a row selector and a column selector unit, the output of which is connected to a sliding register connected to the command issuing unit, one input connected to the number register connected To a digital scoreboard and dialer, and another input - with address buttons, the output of which is connected to the scoreboard address C2J,

Недостатке известного устройства вл етс невысока точность выбора нужных параметров из элементов матрицы.The disadvantage of the known device is the low accuracy of the selection of the desired parameters from the matrix elements.

Цель изобретени - повышение точности устройства дн ввода информа10 1даи.The purpose of the invention is to improve the accuracy of the device for inputting information 10 days.

Дл достижени указанной цели в устройство дл ввода информации, содержащее номеронабиратель, выход которого соединен с входом регистра To achieve this goal, an information input device containing a dialer, the output of which is connected to the register input

15 чисел, выход которого соединен с входЬм первого блока отображени и с первьм входом блока выдачи команд, блок выбора строки, первый выход которого соединен с первым входом 15 numbers, the output of which is connected to the input of the first display unit and with the first input of the command issuing unit, the line selection unit, the first output of which is connected to the first input

20 второго блока отображени ,второй вход которого соединен с первь1м выходом блока выбора столбца, шифратсф , выход которого соединен с входом сдвигового регистра команд, 20 of the second display unit, the second input of which is connected to the first output of the column selection unit, the cipher, the output of which is connected to the input of the shift register of commands,

25 выход которого соединен с вторым входом блока выдачи команд, третий вход которого соединен с первым выходом блока задани адреса, второй выход которого соединен с входом 25 whose output is connected to the second input of the command issuing unit, the third input of which is connected to the first output of the address setting unit, the second output of which is connected to the input

Claims

30 of the third display unit, the first and second counters are inserted, the telB impulses are formed and the comparison unit, the output of which is connected to the encoder input through a pulse shaper, the second output of the row selector is connected to the input of the first counter, the output of which is connected to the first input of the comparison unit, the second input which is connected to the output of the second counter, the input of which is connected to the second output of the block, selection of a column. The drawing shows a block diagram of a device for entering information. The device contains a second display unit 1, a row selection block 2 a column selection block 3, a first counter 4, a second counter 5, a comparison block 6, a pulse shaper 7, an encoder 8, a shift register 9 commands, first mapping block 1.0, register of 11 numbers, dialer 12, address setting block 13, third display block 14, block 1 of instructions. The device works as follows. In the initial state, all three display units are canceled, except for the two extreme columns of the second display unit 1, which contain the names of the classes of commands or numerical characteristics located in the respective lines. When the button of the row selection block 2 is pressed, the first counter 4 is turned on, which performs the construction of the selected numerical characteristic or class of commands, and the line of the second display unit 1 lights up in the same color. The choice of the desired command is achieved by pressing one of the buttons of the block-3 of the column selection, and the second counter 5 is turned on, performing vertical control of the second display block 1, after which the cell corresponding to the selected command changes the color of the glow to another will match the selection of information. At a certain ratio of the numbers recorded by the corresponding bits of the electronic counters (for example, if they are equal, allowing), the signal goes to the inputs of the comparison block and a pulse is generated at the output of the pulse shaper 7 and then the encoder 8 command codes The codes generated from the encoder 8 are received in the shift register 9 of the commands, where the accumulation and fixation of the sequence of input of commands and their issuance to the command issuing unit 15 is carried out. For dialing numeric information, a dialer 12 is provided that is associated with a register of 11 numbers, which provides for the accumulation and fixation of a sequence of numbers. From the register 11 of the numbers, the information enters both the first display unit 10., which contains several digital indicators for the light indication for the purpose of visual control, and the command output unit 15. An output pattern containing the command codes, addresses and numeric information is generated in the command issuing unit 15 and transmitted to external devices. Thus, the introduction of new elements and logical connections ensures the accuracy of the selection of the necessary parameters from the elements of the second display unit, which makes it possible to increase the reliability and efficiency of the device for entering information. The device for inputting information contains a dialer, the output of which is connected to the input of the register of numbers, the output of which is connected to the input of the first display unit and the first input of the command issuing unit, a line selection unit, the first output of which is connected to the first input of the second display unit, the second the input of which is connected to the first output of the column selection unit, the encoder, the output of which is connected to the input of the shift register of commands, the output of which is connected to the second input of the command issuing unit, the third input .co The first is connected to the first output of the address setting unit, the second output of which is connected to the input of the third display unit, characterized in that, in order to improve accuracy, the first and second counters, a pulse shaper and a comparison unit are entered into it, the output of which is connected to the input of the encoder, the second output of the line selector unit is connected to the input of the first Counter, the output of which is connected to the first input of the comparator unit, the second input of which is connected to the output of the second counter, whose input is connected to output of the column selection block. .
