(54) УСТРОЙСТВО ДЛЯ ВВОДА ИНФОРМАЦИИ(54) DEVICE FOR INPUT OF INFORMATION

Устройство относитс к вычислительной технике и может быть использовано в составе средств,предназна-ченных дл ввода информации.The device relates to computing and can be used as part of the means for entering information.

H3BecifHo устройство дл ввода информации , содержащее матрицу коммутационных элементов с вертикгшьньили и горизонтальными шинами и блок управлени . Во включени коммутационного элемента блок управлени вьцдает сигнал наличи кода на выходных шинах устройства 1.The H3BecifHo is an information input device containing a matrix of switching elements with vertical bus or horizontal busbars and a control unit. During the switching on of the switching element, the control unit detects a code presence signal on the output buses of device 1.

Однако это устройство не генерирует сигйалов сдвига кода.However, this device does not generate code shift sigals.

Наиболее близким к предлагаемому вл етс устройство дл ввода информации , содержащее матрицу коммутационных элементов, одни шины которой соединены с первыми входами коммутатора , выходы которого соединены с первым и вторым входги ш триггера, первый выход которого соединен с перBUM входом первого элемента И, выхйд которого соединен с входом первого счетчика, первые выходы которого через дииифратор соединены с другими шинами матрицы коммутационных элементов , генератор.импульсов, выход которого соединен с вторым входом первого элементг И, вторые выходы первого счетчика соединены с входами коммутатора 2.The closest to the present invention is an information input device containing a matrix of switching elements, one bus of which is connected to the first inputs of a switch, the outputs of which are connected to the first and second inputs of a trigger, the first output of which is connected to the first input of the first element And whose output is connected with the input of the first counter, the first outputs of which are connected to the other buses of the switching elements through a diiifrarator, generator pulses, the output of which is connected to the second input of the first element and n, the second outputs of the first counter connected to the switch 2 inputs.

Недостатками известного устройства вл ютс ограниченные функциональ-. ные возможности, обусловленные тем, что устройство -не приспособлено дл работы на шину данных, поскольку не генерирует сигналов наличи кода и сдвига кода, в результате чего шина The disadvantages of the known device are limited functionality. capabilities due to the fact that the device is not adapted to work on the data bus, because it does not generate signals for the presence of code and code shift, with the result that the bus

10 данных занимаетс устройством на врем включени коммутационного элемента , что снижает быстродействие общей системы.10 data is occupied by the device at the time of switching on the switching element, which reduces the speed of the overall system.

Цель изобретени - расширение об15 ласти применени устройства путем дополнительного ввода пачки импульсов.The purpose of the invention is to expand the range of application of the device by additional input of a burst.

Поставленна цепь достигаетс тем, что в устройство введены второй элемент И, второй.счетчик и элемент не20 равнозначности ,. первый вход которого соединен с вторым выходом триггера, первый выход которого соединен с первым входомвторого счетчика, второй вход которого соединен с выходом вто25 рого элемента И, первый вход которого соединен с выходом элемента неравнозначности , второй вход которого соединен с выходом второго счетчика, выход генератора импульсов соединен The delivered chain is achieved by the fact that the second element, the second counter and the element of equivalence, are entered into the device. The first input of which is connected to the second output of the trigger, the first output of which is connected to the first input of the second counter, the second input of which is connected to the output of the second And element, the first input of which is connected to the output of the unequal element, the second input of which is connected to the output of the second counter connected

30 with the second input of the second element I. The drawing shows a block diagram of the proposed device. The device for entering information contains a pulse generator 1, the first and second counters 2 and 3, the decoder 4, the switch 5, the trigger 6, the first BHH) and the second elements 7 and 8, the unequal element 9, the matrix 10 of the switching elements, the output bus 1 Additional information code presence output 12, additional information output of 13 bursts of pulses for code shift. The device works as follows. Clock pulses from the output of the generator 1 pulses through the first element I 7, opened at the second input of the signal from the output of trigger 6, arrive at the input of the first counter 2. Signals from the output of the first counter 2 arrive at the address inputs of the switch 5 and at the inputs of the decoder 4, which provides the generation of interrogation signals of the matrix 10 switching elements When one of the switching elements of the matrix 10 is turned on, the signal arrives at one of the inputs of switch 5, and one of the other inputs of which receives a signal from the output of the first counter 2. From the output of switch 5, the signal goes to the second input of trigger 6, which is triggered. The signal from the first output of the trigger b closes the first element AND 7 and prohibits the arrival of clock pulses on the first counter 2. The signal from the second output of the trigger 6 enters the input of the unequal element 9, on the other input of which the signal of the second GO 3 counts. this, at the output of the element of non-numbered 9, receives a logic: logical signal,. which enters the additional information output 12 and the input of the second element And 8, passes to the input of the second counter 3 and the additional information output 13 pulses from the output of the generator 1 pulses. The signal at the output of the inequality element 9 will be logic until the high bit of the second counter 3 changes its state. Then the output of the inequality element 9 will again be a logical O signal, which closes the second element And 8, stopping the arrival of pulses from the generator 1 output to the input of the second counter 3 and to the additional information output 13, and changes the state of the information output 12. Thus on the information output 13, we get a burst of pulses for writing the output code, for example, in a shift register. In addition, during operation of the proposed device on the data bus, the bus is loaded for the duration of the pulse received at output 12, which increases the speed of the overall system, allowing data to be entered into the computing device when it is working with minimal time. violated.
