SU777431A1 - Bipolar signal registering device - Google Patents

Description

The invention relates to digital computing and is intended to record digital geophysical information in graph form.

A known device for recording electrical analog values is 1.

However, its low speed and inability to record digital information is caused by the fact that the device contains mechanical components.

The closest in technical essence to the invention is a recording device of bipolar signals, comprising a serially connected register, a comparison circuit, a tape drive mechanism and a control device 2.

The aim of the invention is to improve the speed and accuracy when recording information.

This is achieved by introducing a reversible counter, a trigger and a coincidence circuit into the registering device, with the output of the control device connected to the register, to the first inputs of the trigger and reversing counter, the output of the trigger connected to the second inputs of the reversible counter and the comparison circuit. the counter is connected to the third input of the comparison circuit and to the coincidence circuit, the output of which is connected to the second input of the trigger.

In addition, the reversible counter is made in the form of a serially connected counter and switch codes.

In the drawing, a block diagram of a bipolar recording device is shown.

The registering device contains a register /, a comparison circuit 2, a tape drive mechanism 3, a control unit 4, a counter 5, a code switch 6, a multi-input coincidence circuit 7, a circuit driver 8 and input and output terminals 9 and 10, respectively. The counter and commutator switch form a reversible counter 11.

The device works as follows. In a tape drive mechanism (LSM), 3 is a scan along the abscissa. (Along the axis X).

20 is carried out by continuous or discrete movement of the information carrier (for example, electrothermal paper), and the scanning along the axis of ordinates (along the axis Y) is carried out, for example, with a mouse and a screw rotated by a synchronous motor. An information carrier (for example, electrothermal paper) is located between the knife and the knife. The control unit (CU) 4 of the alternating voltage of the LMD 3 (power supply voltage

thirty

synchronous motor) generates counting pulses arriving at the input of the counter 5, and the commands necessary for controlling the electronic circuit of the recorder, command CU 4, received through the terminal

10 to the external device (information source), serves as a request for issuing from the external device to the register input / via terminal 9 a code corresponding to the next value of the ordinate of the output information. Further, by the command LPM 3 about the end of the sweep along the axis Y, the information carrier is shifted by one increment along the axis X, and УУ 4 generates a pulse rewriting the input code into the register / and setting the counter 5 and the trigger 5 to the initial state. In this case, the trigger 5 permits the return code through the switchboard from the output of counter 5 to pass through the switchboard for a time equal to half of the time the sweep is formed along the Y axis. During this time interval, negative information is output, since the trigger is simultaneously significant house, i.e., determines the sign of the information to be displayed, while the code at the output of QC 6 is measured from

11 ... 1 to 00 ... 0. The code 00 ... O is decrypted by the multi-input coincidence circuit 7, the output pulse of which sets the trigger 8 to the one state, while the CC 6 switches and enables the passage of the counter 5 from the forward code . In the second half of the sweep, the code at the output of QC b varies from 00 ... O to 11 ... 1 (write positive values of the output information). At the moment of equality of the code at the output of QC 6 to the code stored in the register /, the comparison circuit 2,

the output signal of which is recorded in the LSM 3 information carrier, etc. Tag. KIM, for each revolution of the auger on the information carrier, one value of the ordinate of the output information is registered.
