Изобретение относится к автоматике и вычислительной технике.The invention relates to automation and computer engineering.

Известны устройства, содержащие источники света, оптически связанные с фотоприемниками, усилители и коммутатор [i] .Known devices containing light sources optically coupled to photodetectors, amplifiers and a switch [i].

Известны также устройства для считывания информации с перфожетона, со держащие источники света, оптически связанные с фотоприемниками, соединенными со входами усилителей, выходы которых соединены с информационными входа ми регистра, а также через элементы И и ИЛИ со входами триггера и распределителя, выходы которых соединены с управляющими входами регистра, блок управления, соединенный с регистром и распределителем [2J .Also known are devices for reading information from a punched-hole counter containing light sources optically coupled to photodetectors connected to amplifiers inputs, the outputs of which are connected to the register information inputs, and also through AND and OR elements with trigger and distributor inputs, the outputs of which are connected to control inputs of the register, a control unit connected to the register and distributor [2J.

Однако у известных устройств недостаточная достоверность считывания информации, так как отсутствуют элементы контроля считываемой информации.However, the known devices lack the reliability of reading information, since there are no controls for reading information.

Цель изобретения - повышение достоверности считывания информации с перфожетона.The purpose of the invention is to increase the reliability of reading information from a perforator.

Цель достигается тем, что в известное устройство введены дополнительный коммутатор и компаратор, выход которого соединен с управляющим входом блока управления, а первая и вторая группы информационных сигналов соединеы с соответствующими выходами усилителей и дополнительного коммутатора, управляющий и информационные входы которого соединены соответств’енно со вторым выходом распределителя и информационными выходами регистра.The goal is achieved by the fact that an additional switch and a comparator are introduced into the known device, the output of which is connected to the control input of the control unit, and the first and second groups of information signals are connected to the corresponding outputs of the amplifiers and the additional switch, the control and information inputs of which are connected respectively to the second the output of the distributor and the information outputs of the register.

На чертеже представлена функциональная схема устройства.The drawing shows a functional diagram of the device.

Устройство содержит жетон 1, узел 2 перемещения жетона, источники 3 света, фбтоприемники 4, усилители 5, элемент ИЛИ 6, распределитель 7, элементы 8 и 9 И,триггер 10, дополнительный коммутатор 11, компаратор 12, регистр 13, коммутатор 14 и блок 15 управления.The device comprises a token 1, a token moving unit 2, light sources 3, photodetectors 4, amplifiers 5, an OR element 6, a distributor 7, I elements 8 and 9, a trigger 10, an additional switch 11, a comparator 12, a register 13, a switch 14, and a unit 15 controls.

Устройство иаботает следующим образом.The device operates as follows.

Ввод информации с жетона 1 производится в три этапа. В первом этапе производится считывание информации с жето- 5 на 1 при его опускании в тракт узла перемещения жетона 2. Во втором этапе производится вытягивание жетона 1 с тракта узла 2 перемещения жетона с повторным считыванием информации и срав- 10 нением ее с инфоомацией, зафиксированной при опускании жетона. В третьем этапе информация с регистра 13 с помощью блока 15 управления выводится во внешнее устройство. 15Entering information from token 1 is carried out in three stages. In the first stage, information is read out from the 5–1 to 1 when it is lowered into the path of the token transfer unit 2. In the second stage, the token 1 is drawn from the path of the token transfer unit 2 with repeated reading of the information and its comparison with the information recorded at lowering the token. In the third stage, information from the register 13 using the control unit 15 is output to an external device. fifteen

При опускании жетона 1 информация жетона вопринимается фотоприемниками 4 и усиливается усилителями 5. С выходов усилителей 5 информация записывается в регистр 13. Последовательностью записи информации в регистр 13 управляет распределитель 7, на входы которого с выхода элемента ИЛИ 6 поступают импуль сы синхронизации, считываемые усилите- ₂g лями 5 с 1-го или УП-ого столбцов же тона (в зависимости от ориентации жетона в узле перемещения).When lowering the token 1, the information of the token is received by photodetectors 4 and amplified by amplifiers 5. From the outputs of amplifiers 5, information is recorded in register 13. The sequence of writing information to register 13 is controlled by a distributor 7, to the inputs of which synchronization pulses from the output of OR 6 are received, read out by amplifiers ₂ g by 5 from the 1st or UP columns of the same tone (depending on the orientation of the token in the displacement node).

Распределитель 7 представляет собой кольцевой счетчик с количеством выходов, равным двойному количеству двоичных разрядов информации столбца. Первые вы ходы кольцевого счетчика соединены с входом регистра 13 и обеспечивают поразрядное управление записью информации, считываемой с жетона 1 при опускании ³⁵жетона в тракт узла 2.The distributor 7 is a ring counter with the number of outputs equal to twice the number of binary bits of the column information. The first outputs of the ring counter are connected to the input of the register 13 and provide bitwise control of the recording of information read from the token 1 when the ³⁵ tokens are lowered into the path of the unit 2.

При вытягивании жетона 1 информация с усилителей 5 поступает на вход компаратора 12 в обратной последовательности. Входы регистра 13 для этой информации ⁴⁰блокированы распределителем 7. Каждый синхроимпульс, поступающий на вход распределителя 7, изменяет его состояние. Вторые входы распределителя 7 соединены с первым входом дополнительного ⁴⁵коммутатора 11, на второй вход которого подается информация, записанная в регистр 13 при опускании жетона 1 в тракт узла 2. Вторые выходы распределителя 7 обеспечивают на выходе дополнительного коммутатора 11 коммутацию информации регистра 13 на вход компаратора 12 в обратной последовательности и через дополнительный коммутатор 11 разрешают' работу компаратора 12. Таким образом, 55 в компараторе 12, синхронно с поступлением импульсов синхронизации на распределитель 7, производится сравнение ин30 формации регистра с информацией, считываемой с жетона 1 при его выталкивинии с тракта узла перемещения 2. При несовпадении информации на выходе компаратора 12 формируется сигнал Сбой*, который поступает в блок 15 управления и блокирует последующий вывод информации с регистра 13 через коммутатор 14 во внешнее устройство. При этом требуется повторный ввод информации с жетона 1. Перед повторным вводом или в начале работы блок 15 управления формирует сигнал 'Начальная установка, который устанавливает исходные состояния распре-. делителя 7 и регистра 13.When pulling the token 1 information from the amplifiers 5 is fed to the input of the comparator 12 in the reverse order. The inputs of the register 13 for this information ^{40 are} blocked by the distributor 7. Each clock pulse supplied to the input of the distributor 7 changes its state. The second inputs of the distributor 7 are connected to the first input of the additional ^{45 of the} switch 11, the second input of which serves the information recorded in the register 13 when the token 1 is lowered into the path of the node 2. The second outputs of the distributor 7 provide the output of the additional switch 11 switching the information of the register 13 to the input of the comparator 12 in the reverse sequence and through an additional switch 11 enable 'the operation of the comparator 12. Thus, 55 in the comparator 12, synchronously with the arrival of synchronization pulses to the distributor 7, produced A comparison is made of the register information 30 with the information read out from the token 1 when it is ejected from the path of the displacement unit 2. If the information does not match, the output of the comparator 12 generates a Fault * signal, which enters the control unit 15 and blocks the subsequent output of information from the register 13 through the switch 14 to an external device. This requires re-entering information from the token 1. Before re-entering or at the beginning of operation, the control unit 15 generates a signal 'Initial setting, which sets the initial state of the distribution. divider 7 and register 13.

При совпадении информации на входах компаратора 12 на его выходе формируется сигнал ‘Готовность, который поступает в блок управления 15. и таким, образом разрешается вывод информации во внешнее устройство.When the information coincides at the inputs of the comparator 12, a signal ‘Ready is generated at its output, which enters the control unit 15. And thus, the output of information to an external device is allowed.

Сигналы-запросы посимвольно ввода информации с регистра 13 поступают в блок управления выводом информации 15 с блока внешнего управления 16. Блок управления информации 15 обеспечивает посимвольное управление* выводом информации регистра 13 через коммутатор 14 во внешнее устройство.The request signals symbolically input information from the register 13 are received in the information output control unit 15 from the external control unit 16. The information control unit 15 provides symbol-by-word control * the output of the register information 13 through the switch 14 to the external device.

Коммутатор 14 обеспечивает правильную коммутацию на вход блока управления кодовых информационных сигналов регистра 13 независимо от ориентации жетона 1 относительно вертикальной оси при считывании с помощью триггера 10.The switch 14 provides the correct switching to the input of the control unit of the code information signals of the register 13, regardless of the orientation of the token 1 relative to the vertical axis when read using the trigger 10.

Триггер 10 обеспечивает фиксацию изменения ориентации жетона 1 в узле перемещения жетона 2 относительно вертикальной оси. При считывании информации с жетона 1 синхродорожка располагается в одном из крайних столбцов (в 1-4л или УИ-м) и поэтому на одном из входов элементов И в момент появления импульса синхронизации, поступающего с выхода элемента ИЛИ 6, сигнала не будет на том входе, где будет считываться столбец с цифровой информацией, так как в столбце с информацией в отличии от столбца с синхродорожкой обязательно одна из двоичных ячеек затемнена. Цифры 0,1-9 представляют набор чередующихся двоичных элементов кода О* или1. Триггер 10 фиксирует отсутствие на входе соответствующего элемента И 8 и 9 сигнала и устанавливает на входе коммутатора 14 сигнал, определяющий ориентацию жетона относительно вертикальной оси. Таким образом, при выводе информации с регистра 13 коммутатор 14 обеспечивает правильную коммутацию информации.The trigger 10 provides a fixation of the orientation change of the token 1 in the node of movement of the token 2 relative to the vertical axis. When reading information from counter 1, the sync track is located in one of the extreme columns (1-4L or UI-m) and therefore, at one of the inputs of the AND elements, at the time of the appearance of the synchronization pulse coming from the output of the OR 6 element, there will be no signal at that input , where a column with digital information will be read, since in a column with information, unlike a column with a sync track, one of the binary cells is necessarily darkened. Numbers 0,1-9 represent a set of alternating binary elements of the code O * or1. The trigger 10 detects the absence at the input of the corresponding element And 8 and 9 of the signal and sets the signal at the input of the switch 14, which determines the orientation of the token relative to the vertical axis. Thus, when outputting information from the register 13, the switch 14 provides the correct switching of information.

Технико-экономический эффект от использования предложенного изображения 5 заключается в повышении достоверности считывания информации с перфожетона за счет двукратного считывания и сравнения информации считанной при вытягивании жетона с информацией считанной при опускании жетона.The technical and economic effect of using the proposed image 5 is to increase the reliability of reading information from the punched-hole token by double-reading and comparing the information read when pulling the token with the information read when lowering the token.

Claims

This invention relates to automation H computing. Devices are known that contain light sources optically coupled to photo receivers, amplifiers, and switch ij; Also known are devices for reading information from a perforator, containing light sources optically coupled to photo detectors, connected to inputs of amplifiers, the outputs of which are connected to the information inputs of the register, as well as through the AND and OR elements to the inputs of the trigger and distributor, the outputs of which are connected to the control inputs of the register, the control unit connected to the register and the distributor 2, However, the known devices lack the accuracy of reading information, since there are no control elements l-readable information. The purpose of the invention is to increase the reliability of reading information from perfozhetona. The goal is achieved by introducing an additional switch and a comparator into a known device, the top of which is connected to the control input of the control unit, and the first and second groups of information signals are connected to the corresponding outputs of the amplifiers and the additional switch, the control and information inputs of which are connected respectively to the second distributor output and register information outputs. The drawing shows the functional scheme of the device. The device contains a token 1, a node 2 moving the token, sources of light 3, photodetectors 4, amplifiers 5, element OR 6, distributor 7, elements 8 and 9 AND, trigger 1O, additional switch 11, comparator 12, register 13 ,, switch 14 and control unit 15. The device also works as follows. Information input from a token 1 is performed in three stages. In the first stage, information is extracted from the token 1 when it is lowered into the path of the token 2 displacement unit. In the second stage, the token 1 is pulled out from the path of the token 2 relocation node with the information reread and compared with the information recorded when the token is lowered. In the third stage, information from register 13 with the help of control unit 15 is output to an external device. When the token 1 is lowered, the information of the token is received by the photoreceivers 4 and amplified by amplifiers 5. From the outputs of amplifiers 5, information is recorded in register 13. The sequence of recording information in register 13 is controlled by a distributor 7, to the inputs of which the output element OR 6 receives synchronization pulses readable by the amplifier mi 5 with IHTO or UH-south of the token columns (depending on the orientation of the token in the switch node). The distributor 7 is a ring counter with a number of outputs equal to twice the number of binary bits of the column information. The first outputs of the ring counter are connected to the input of the register 13 and provide random control of the recording of information read from the token 1 when the token is lowered into the path of the node 2. When drawing the token 1, information from amplifiers 5 is fed to the input of the comparator 12 in reverse order information is blocked by the distributor 7. Each clock pulse arriving at the input of the distributor 7 changes its state. The second inputs of the distributor 7 are connected to the first input of the additional switch 11, the second input of which is supplied with information recorded in register 13 when the token 1 is lowered into the path of node 2. The second outputs of the distributor 7 provide for switching the information of the register 13 to the input of comparator 12 at the output of additional switch 11 in reverse order and through) an additional switch 11 allows the comparator 12 to work. Thus, in KONfnapaTOfje 12, synchronously with the arrival of pulses of the phytophone on the distributor 7, it is produced with Registering information from a register with information read from a token 1 when it is pushed out of the path of the motion node 2. If the information does not match, the output of the comparator 12 generates a Failure signal that enters the control unit 15 and blocks the subsequent output of information from the register 13 through the switch 14 to an external device . At the same time, it requires a re-entry of information from the token 1. Before re-entering or at the beginning of operation, the control unit 15 generates a signal Initial setting, which sets the initial states of the distribution. divider 7 and register 13. If the information at the inputs of the comparator 12 coincides, the Ready signal is generated at its output, which goes to the control unit for 15 hours and so. information output to the external device is allowed. Signals-requests for input information from the register 13 character-by-one are fed to the information output control unit 15 from the external control unit 16. The information information control unit 15 provides the letter 13 information output of the register 13 through the switch 14 to an external device. Switch 14 provides correct switching to the input of the control unit of the code information signals of register 13, regardless of the orientation of the token 1 relative to the vertical axis when read using trigger 1O. The trigger 10 fixes the change in the orientation of the token 1 in the node for moving the token 2 relative to the scale axis. When reading information from the token 1, the sync path is located in one of the outermost columns (V or UE), and therefore at one input of the elements AND at the time of the synchronization pulse coming from the output of the element OR 6, there will be no signal at that input It will count from a column with digital information, since the column with information, unlike the column with the S1 track, is necessarily darkened from binary cells. 0.1 to 9 represent a set of interleaved binary elements of the code O or. The trigger 10 detects the absence of a signal at the input of the corresponding element AND 8 and 9 and sets at the input of the switch 14 a signal that determines the orientation of the token relative to the vertical axis. Thus, when information is output from the register 13, the switch 14 ensures the correct switching of information. The technical and economic affect of the designation of the proposed image is to increase the reliability of reading information from the perforanton by double reading and comparing the information read when pulling the token with the information read when the badge was lowered.
