(54) DEVICE FOR REGISTRATION OF INFORMATION

one

The invention relates to computational and instrumentation technology and can be used in control systems for recording any physical processes.

Known devices for recording information 1, 2.

One of the known devices comprises a registration unit connected to the control unit, switches connected to the memory unit, and a trigger.

The device for recording information closest to the invention contains us-blocks connected to a comparison unit connected to a first control unit connected via a first switch, an electronic clock and a second control unit to a printing mechanism connected in series, a generator connected through a frequency divider to the first block control and through the second switch to the third switch connected to the second control unit connected via the fourth switch to the first control block, integrated with an electronic clock, second switch and second control unit 2.

The known device has a low accuracy of fixing the state of the electronic clock when registering a parameter associated with the loss of time in searching and switching the source of the registered parameter.

The purpose of the invention is to improve the accuracy of the device for recording information. This is achieved by the fact that the device for registering information contains a trigger and a key block, one of the inputs of which is connected to the trigger output and the first control unit, its other inputs are connected to the outputs of the third switch, one of the outputs is connected to the first trigger input, the second input which is connected to the comparison unit, and the other outputs - with the inputs of the comparison unit.

The drawing shows a block diagram of a device for recording information.

The device contains memory blocks 1 and 2, comparison block 3, trigger 4, first control block 5, generator 6, frequency divider 7,

first 8, second 9, third 10 and fourth 11

switches, digital clock 12, second

control unit 13, printing mechanism

14, a block of 15 keys.

Blocks 1 and 2 of the memory are connected to the parameter sources (sensors) and to the comparison unit 3, to which the key block 15 is connected, connected to the switch 10, the trigger 4 and the control block 5. The unit 5 is connected via a serially connected switch 8, an electronic clock 12 and a control unit 13 connected to a printing mechanism 14, as well as to an electronic clock 12, a control unit 13, a switch II, a trigger 4, a comparison unit 3 and a frequency divider 7. Frequency 7 is connected to generator b, which is connected to switch 9, and switch 9 is connected to switch 10.

A device for recording information as follows.

Upon receipt of the input information triggers are triggered cells of blocks 1 and 2 of memory. The signals from the outputs of the blocks 1, 2 are fed to the inputs of the block 3 of the comparison. At the output of block 3, a differential appears, from which the trigger 4 is triggered, the level from the trigger output closes the key block 15 and starts the control block 5 allowing the passage of pulses from the generator 6 through the frequency divider 7 to the input of the switch 8, with which the time information the occurrence of the recorded signal is output from the electronic clock 12 through the control unit 13 to the printing mechanism 14. Thus, the occurrence time of at least one recorded signal is printed first.

Upon completion of printing, control unit 13 sends a signal to control unit 5, which prohibits the passage of pulses from generator 6 through frequency divider 7 to input of switch 8 and allows passage of pulses from generator 6 through switch 9 to input of switch 10. Switch 10 sequentially through key block 15 polls the state of the same-named triggers of memory blocks 1 and 2, the parameters being fed to the inputs of the registers in order of importance, i.e. the most important parameters are evaluated first.

When a priority parameter is detected, a differential appears again at the output of the comparator unit, according to which the control unit 5 closes the switch 9 and opens the switch 11. The output pulses of the switch 11 through the block 13 control the printing of the state of the switch 10 by the printing mechanism 14.

Upon the completion of printing of the number of the registered riapaMeTpa, control unit 13 outputs a control signal to control unit 5, which opens switch 9, and polling continues. After polling the last cells of the blocks 1

and 2 memories; a block of 15 keys gives impulse

reset to trigger 4.

Device for recording information

allows to improve the accuracy of the time of the recorded parameters while ensuring the priority of the registration of the parameters, which is the technical and economic effect of the invention.
