(54) DEVICE FOR ENTERING INFORMATION

one

The invention relates to the field of automation and computer technology and can be used to enter alphanumeric information into a computer.

A device is known for inputting the information of the MS, comprising a keyboard, an encoder, an automatic character input unit, an output register, a unit for generating the end of parcel signal and a control unit.

However, such a device does not provide a visual representation and the possibility of prompt correction of the formed messages. In addition, in Het-i there is no automatic control of the operation of the device, which reduces its reliability and limits its functionality.

The closest to the technical essence of the invention is a device for inputting digital information r2j, containing serially connected in a typing field, an intermediate register and a digital scoreboard connected to an intermediate register, a scoreboard connected to a typing field, a memory block, an intermediate register, scoreboard parameters connected to the memory unit, as well as the control unit connected to the memory unit by the input and output, the output from the parameter board command board, the spindle register and the output buffer Trunk.

The disadvantage of the device is the lack of automatic control of the processes of @ m @ {information flow between its elements, which reduces its reliability.

The aim of the invention is to increase the reliability of the device.

This goal is denoted by the fact that the device for entering information contains a keyboard, an operational memory unit and a long-term memory unit, the output and input of which are respectively cc) with the first input and the first output at the end.

20 input block, the element I, the element IL, the first and second triggers and the switch, the information inputs KOTOpQro are connected to the outputs of the corresponding keyboards, the output 25 to the second input to the control panel and the single input of the first trigger, the control input to the third output control unit, to the control input of the operative memory unit, to the first input of the eletneit Neither to the single input of the second trigger, zero, whose input is connected to the first output of the main memory unit and the device output. The fourth output of the control unit is connected to the second input of the AND element, the fifth output to the information input of the RAM unit, the third input to the second output of the RAM unit, the Output of the AND element is connected to the zero input of the first trigger. The outputs of the first and second triggers are connected to the corresponding inputs of the OR element, the output of which is connected to the fourth input of the control unit.

The drawing shows a block diagram of the device for entering information, where keyboard blocks 1, switch 2, device output 3, fixed memory block 4, control block 5, indication block b, random-access memory block 7, first and second triggers 8 and 9, element And 10, element OR 11.

The device works as follows.

The operator from one of the blocks of the keyboard 1 sends through the switch 2 to the block 5 the code of the required command. Block 5, according to the corresponding program of block 4, samples the sequence of the kodo of the required form with a corresponding list of parameters, which is a constant part of the message currently being generated by the device.

This information is recorded in block 7, from where it is displayed on the screen of block b and is regenerated by block 5.

Using the selected block 1, the operator performs the filling of the form, forming the alphanumeric values presented in block 6. parameters. All the character codes entered from block 1 are recorded under the control of block 5 into the corresponding cells of block 7 and then regenerated on the screen of block 6. It is possible that one message is simultaneously generated by several operators, each of which inputs numerical values of the corresponding parameters from its own keyboard. One of the operators may be charged with correcting and approving the message being generated.

To eliminate the overlay of information generated by different operators, each of them is allocated the corresponding screen area of block 6, containing one or several pargadres. The size of each zone is variable and is set using the service keys of blocks 1. Switch 2 provides sequential input to block 5 of character codes entering its information inputs at

Simultaneous keystroke on multiple keyboards.

Thus, the device provides both individual and collective work of several operators for the formation of a single message.

The device automatically controls the input and output processes. So when entering into the device, from blocks 1 of each character, trigger 8 is set to state 1. When writing the symbol code in block 7, block 5 generates a special signal for rewriting the entered character, which through the control output goes to one of the inputs of the And 10 element. If there is a control signal at the second input of the And 10 element that accompanies each character code recorded in block 7, the trigger 8 is set to the initial

condition. The state of the trigger 8 is analyzed by block 5 after writing to block 7 of each character code entered from block 1. In case of failure

In block 5, when processing the entered character code, trigger 8 remains in the set state by the moment of the next cycle of analysis of its state by block 5. In this case, block 5

selects from the code 4 code the special symbol of the alarm situation of the faulty situation and outputs it to the highlighted cell of the display panel of the block 6.

Issue each character code from

the block 7 to the output 3 is carried out according to the control signals of the block 5. At the same time, the trigger 9 is set to one state. Upon arrival at exit 3 of block 7 of the character code, trigger 9 is reset. The state of the flip-flop 9 is analyzed by block 5 after each cycle of outputting at the output 3 of the next character code. In the event of a failing situation (issuing

the symbol code did not occur at the output) the trigger 9 remains in the cocked state, and in the selected cell of the block b, the symbol of the alarm situation of the faulty situation is similar to that described above.

In order to eliminate faulty situations due to the appearance at the input of block 5 of the character code entered from one of the blocks 1 at the moment of organization

the processor issuing the next symbol from block 7 to output 3, the switch 2 is blocked by the control signal of block 5.

 Thus, the field of application of the device is expanded, since the formation of informational messages is ensured both in the p-mode of the individual work of the operator, and in the mode of collective and work of the group of operators. In addition, the proposed device provides a visual display
