Description

. . 1 . Изобретение относитс к области вычислительной техники и может быть использовано в автомат1;5зированных системах управлени тexнoлorичecки ш « процессами дл ввода информации о параметрах объекта, представленных в виде аналоговьк величин, в электронную машину. . . one . The invention relates to the field of computer technology and can be used in automated processes of technological control systems for entering information about the parameters of an object, presented in the form of analog values, into an electronic machine.

Известно устройство дл ввода ин- Ю формации в ЭВМ, содержащее аналогоцифровой преобразователь, коммутатор, блок сопр жени и блок управлени 1.A device for inputting information into a computer is known, comprising an analog-digital converter, a switch, a interface unit and a control unit 1.

Недостатком этого устройства вл -|$ етс его сложность.A disadvantage of this device is its complexity.

Наиболее близким техническим реше нием к изобретению вл етс устройство дл ввода информации в ЭВМ, оодержаиее последовательно соединенные 20 коммутатор, аналого-цифровой преобразователь и буферный регистр, одни входы которого подключены к блоку сопр жени , а выходы - к ЭВМ блок управлени , соединенный с коммутато- 2 ром, аналого-цифровым преобразователем и блоком сопр жени 2).The closest technical solution to the invention is a device for inputting information into a computer, a switchboard connected in series, an analog-to-digital converter and a buffer register, one input of which is connected to a gateway and outputs to a computer connected to a switchboard. - 2 rum, analog-digital converter and interface unit 2).

Недостатком этого устройства вл етс больша избыточность вводимой информации. 30A disadvantage of this device is the large redundancy of the input information. thirty

Целью изобретени вл етс расширение , ббл ас тй прймёнёТнй усТро йс тв а путем исключени избыточности информации . . i Цепъ достигаетс тем, что устройство дл ввода информации в ЭВМ содержит блок сравнени и блок пам ти, входы которого соедг1нены с ЭВМ, блоком сопр жени и блоком управлени , а выходы - с блоком управлени и блоком сравнени , соединенным с блоком управлени .The aim of the invention is to expand, to provide a way to do so by eliminating redundancy of information. . The circuit is achieved by the fact that the device for inputting information into the computer contains a comparison unit and a memory unit whose inputs are connected to the computer, the interface unit and the control unit, and the outputs are connected to the control unit and the comparison unit connected to the control unit.

Блок-с:4ема устройствй представлена на чертеже.Block-s: 4ema device presented in the drawing.

Устройство содержит коммутатор 1 каналов, аналого-цифровой преобразователь 2, блок 3 управлени , буферный регистр 4, блок 5 сопр жени , блок б сравнени и блок 7 пам ти. .The device comprises a switch 1 of channels, an analog-digital converter 2, a control unit 3, a buffer register 4, a conjugation unit 5, a comparison unit b and a memory unit 7. .

Устройство работает следующим образом .The device works as follows.

Работа может производитьс в трех режимах: ввод пО запросу от ЭВМ; ввод группы параметров с последовательными адресами; ввод отдельных параметров .The work can be performed in three modes: input upon request from a computer; entering a group of parameters with consecutive addresses; input of individual parameters.

Claims

When operating in the first mode, the device receives a Readiness signal at the input of the interface 5, which, according to this signal, generates the Device Readiness signals and the output synchronization signal received at the device inputs. In response to the indicated signals from the computer 8, the mode KD is fed to the input of the memory unit 7. On the Recording Signal coming from the Interface 5, information is recorded. After the signal is removed, the readiness of the computer of the interface block generates a measurement signal arriving at the input of the control unit 3. On this signal, the control unit generates a census signal. memory The latter arrives at the input of the memory block 7 and rewrites the contents of the block 7 into the control block 3. Then the control unit generates a power connection channel, through which switch 1 connects to the input of the analog-digital converter 2 with a corresponding channel. The measurement is performed on the Start signal coming from the output of control unit 3 to the input of an analog-to-digital conversion of body 2, which generates the signal Digitization input to the input of the control unit. On this signal, the control unit generates a data entry signal, which is input to the interface unit 5 and is converted into a data recording signal, which controls the recording of information in the buffer register 4. After that, the interface unit generates a device readiness signal. Thus, the information is ready for input into the computer and is entered on the corresponding signal. . . . Similarly, the input of other parameters is carried out. The operation of the device in the second mode differs from the first in that the codes of the first and last addresses of the group MeTpipB are recorded in the memory unit 7. At the same time, in the comparison block b, the code of the last parameter group address arriving at the inputs of the comparison block 6, memory block 7 with the current address of the measured parameter coming from the control unit is compared to the control unit in case of equality from the comparison block. The device waits for the receipt of the request request from the computer 8. The operation of the device in the third mode is organized in the same way as in the second, with the only difference being that memory unit 7 is recorded on the codes of the first and last addresses of the parameter group, and the addresses of individual parameters. An apparatus for inputting information into a computer, comprising a series-connected switch, an analog-to-digital converter and a buffer register, one input of which is connected to the interface unit, and the output to the computer, a control unit connected to the switch, analog-digital converter and the unit interface, in order to expand the scope of application by eliminating redundancy of information, it contains a comparison unit and a memory block whose inputs are connected to a computer, an interface block and a block control com, and outputs - to the control unit and the comparison unit, connected to the control unit.
