SU570907A1 - Device for recording information - Google Patents

Description

one

The invention relates to computing and can be used to register information, in particular, primary information in automated control systems.

Information recording devices are known that contain sensors (keyboards, card readers, tokens, etc.) whose outputs are connected via a buffer register to informational inputs of information receivers (printing devices, tape punching devices, etc.) and with a decoder connected to the inputs of the control unit, the outputs of which are connected to the control inputs of the polling unit for sensors and receivers, and the switching inputs of the polling unit for receivers are connected via OR elements to the pushbutton switch block one.

The disadvantage of such devices is low reliability of operation, due to the large number of errors made by the operator in the process of forming the layout of the recorded message (document) handed using push buttons.

It is also known that the device for recording information, which is closest to the technical solution of the invention, contains sensors, the outputs of which are connected to information inputs through a buffer register.

receivers and a decoder connected to the control inputs of the control unit, the first and second outputs of which are connected respectively to the control inputs of the sensor and receiver interrogation units, and the switching inputs of the receiver interrogation unit OR are connected to the button switches 2.

However, with the prevalence in the recorded

messages of variable information entered by the operator from the keyboard, the program mode of forming the message layout does not provide (besides the convenience of the operator) any significant advantages

and manual mode. At the same time, the presence of a software message generation unit significantly complicates the device.

The purpose of the invention is to increase the reliability and simplify the device for recording information.

This is achieved by the fact that the address register of the sensors, a switching unit and an additional block of pushbutton switches, connected to the second inputs, are entered into the device.

the control unit and the first inputs of the sensor address register, the second inputs of which are connected with the third inputs of the control unit and the address outputs of the sensors, the third inputs with the third and fourth outputs of the block

and the outputs are connected to the information inputs of the sensor polling unit and through the switching unit to the second inputs of the OR elements.

The specified construction of the scheme provides a semi-automatic formation of a message (document) layout based on the program specified with the help of the switching panel. This achieves high reliability of operation due to the simplification of the operation of the olerator on the device, as well as saving equipment due to the simplified design of the device for recording information compared with the prototype.

The block diagram of the device shown in the drawing.

The device contains sensors 1, a register of 2 addresses of sensors, a control unit 3, a block of 4 pushbuttons, a sensor 5 / (type) reader of punched cards, tokens, etc.), an additional block of 6 pushbutton switches, a unit 7 of sensor polling, a buffer register 8, receiver polling block 9, switching unit 10, elements OR 11, receivers 12, descrambler 13.

At the beginning of work on the device, the operator selects an information sensor, from which the first word (group of characters, limited by the "information separator" symbol of the registered message) is entered.

The selection of sensors 1 (sensors of the keyboard type) is made at the moment of typing the first key, i.e. pressing the first key on the keyboard. At this moment, the address output of the sensor 1 and the inputs of the register 2 of the addresses of the sensors and the control unit 3 receive a signal that the control unit sends to the register 2 a resolution signal that addresses the addresses of sensor 1 to the register 2 and this address is written.

The selection of sensors 5 (reader reader with punched cards, tokens, etc.) is carried out by the corresponding instantaneous button in the additional unit 6 pushbutton switches. The signal from the output of block 6 records the address of sensor 5 into register 2 of addresses of sensors in the same order as for sensors 1.

After selecting a sensor, block 3 sends a control signal, according to which block 7 of sensor polling generates a signal called sensor call, which enters the input of either sensor 1 (or 5) whose address is currently recorded in register 2. At the signal called sensor call sensor 1 (or 5) transmits one information symbol to the buffer register 8. Thereafter, control block 3 generates a call enable signal for the receivers, which is input to the receiver polling block 9.

The addresses of the receivers to which the symbol coming from the selected sensor should be set are performed prior to starting operation using the switching variable in block 10. In this block, the outputs of the register 2 of the addresses of the sensors that are connected to the inputs of block 10 are switched,

with the inputs of the elements OR 11 connected to the outputs of blocks 10 and 4.

When writing the address of the sensor in register 2, the signal from the corresponding output of this register goes through block 10 and the elements OR 11 to the corresponding inputs of block 9 of polling receivers. Thus, a pre-established hard coupling between the selected sensor and some set of receivers 12,

To which information should be transmitted from this sensor.

According to the signal from control unit 3, unit 9 generates signals "Receiver call, arriving at information inputs of information receivers 12 selected by the iSM method. The symbol from the buffer register goes to the selected receivers 12. Then the control unit again generates a sensor call enable signal, writes the next character to the buffer register 8 and sends it to the receivers 12. This order of work is saved until the buffer register The service symbol “Information separator meaning

koiets words. The symbol is decoded by the decoder 13, the output of which transmits the signal to the control unit 3. For this sigial, block 3, after transmitting the symbol "information separator to receivers 12, generates

The “blanking” signal, which is fed to the input of the register of 2 addresses of sensors and suppresses an undefined address of the sensor.

Further work begins with the re-selection of the sensor and continue in the described

order for the next word of the message (document).

If necessary, change the set of receivers associated with a particular sensor, the operator, and the choice of

the sensor can produce the operational setting of the addresses of the receivers using the buttons with fixation in the block of 4 push-button switches. The signals from the outputs of this block come through the elements OR 11 to the inputs of the block

9 survey receivers. Due to this, the signals “The call of the receiver will be sent also to those receivers whose addresses are specified using block 4. Technical and economic effect of the proposal

is to simplify the device and increase its reliability.
