Description

The invention relates to automation and computer technology and can be used in the study of single and periodic signals in medicine, seismic exploration, nuclear physics, and other fields of science and technology. A device comprising a series-connected sensor, a measuring amplifier, an analog-digital converter, a memory unit, a control circuit, a time counter, a trigger, an AND circuit, a registration start block, a clock generator, and a control unit 1 is known. The disadvantage of this device is the impossibility of shifting signal, which reduces the functionality of the device. It is also known a device containing an amplifier connected in series, an analog-to-digital converter, a display device 2 The disadvantages of this device include the absence of pre-start recording, the inability to shift the image of a recorded signal in memory, which reduces its functionality and accuracy characteristics when changing its parameters with respect to some level or signal. Closest to the invention is a device for displaying information comprising a serially connected switch, an analog-to-digital converter, a memory unit connected to a control unit connected to the first switch and a matrix display panel. The disadvantage of this device is the inability to shift the signal along the vertical axis, which significantly reduces the functionality of the device when examining signals from several sensors. The absence of a signal shift along the vertical axis makes it impossible to combine two or more signals displayed on a display device, which makes it difficult to determine the time shifts between them and the magnitude of amplitude parameters and leads in turn to significant measurement errors. The purpose of the invention is to improve the accuracy of the device by automatically shifting each memorized ordinate of the signal by an amount set by the operator.

This goal is achieved by the fact that a device for displaying information containing a serially connected switchboard, an analog-digital converter, a memory unit connected to a control unit connected to the first switchboard and the matrix display panel, additionally contains a reversible counter, registers second and third switches, a digital null-organ counter and an And element, with the output of the memory unit connected to the first input of the reversible counter, the second input of which is connected to one output of the second switch, the other the output of which is connected to the first input of a digital null organ, the second input of which is connected to the output of the counter, and the output to the input of the third switch and the first input of the And element, the second input of which is connected to the output of the control unit and one input of the counter, the other input of which is connected to the control unit and the matrix indicator panel connected to the output of the third switch, whose input is connected to the output of the reversible counter, the output of the AND element is connected to the third input of the reversible counter, the outputs of the control unit and connected to the second switch and the registers connected to the second switches.

The drawing shows a block diagram of the device.

The device contains a switch 1, an analog-digital converter 2, a block of pam 3, a reversible counter 4 a second switch 5, a matrix display panel b, a control unit 7, a counter 8, a digital null organ 9, element 10, registers 11, a third switch 12 , switches 13 and 14, buttons 15 and 16,

The input signals, f U n, are fed to the analog signal switch 1. The sequence of passing these signals to the input of the analog-digital converter 2 is determined by a command from the control unit 7 to the control input of the switch 1. The instantaneous values of the ordinates of the signals are encoded by the analog-digital converter 2 and a control command from block 7 is recorded in memory block 3. After the end of the recording process, the coded values of the ordinates of the signals are output for display on the matrix display panel b. The belonging of each curve to the display device 6 to its channel is distinguished, for example, by means of luminance modulation or another method. In order to shift a particular signal, the operator

selects the channel number with the help of switches 13 and 14 and with the help of buttons 15 and 16, which are included in the control unit i, sets the lower

up

shift shift

or

For example, in order to shift the signal registered on the first channel, it is necessary to place the switches 13 and 14 in position. Then by pressing buttons 15 or 16, the direction of shifting up or down is recorded in registers 11, and the amount of shift, which depends on the duration of pressing button 15 or 16, is written to the registers by a signal from the control unit. Similarly, the value of the direction of shift for each channel is recorded.

Consider the mode of displaying information, for example, the first channel. With the arrival of the first coded ordinate value, the reversible counter 4 is set to the position corresponding to the ordinate code. Then, with a control command from block 7, switch 5 connects the register defining the direction of the shift of the first channel of block 11 to the addition or subtraction input of the reversible counter 4. At the same time switch 5 connects the output of the register determining the shift of the first channel to the input of the digital zero-organ, another the input of which is connected to the output of the binary counter. The pulses, ensuring a shift of the encoded value of the ordinates, will be fed to the input of binary counter 8 and simultaneously through the AND element to the input of the reversible counter 4, changing the code value in it, which corresponds to moving the ordinate on the display device up or down depending on the command recorded in the registers 11. If the shift value recorded in register 11 is equal to the code at the output of binary counter 8, digital null-authority 9 is prohibited. the passage of pulses through the element And 10 to the input of the reversible counter 4. This corresponds to the fact that the necessary shift in the ordinate is completed. The output signal of the digital null-organ resolves the output of the ordinate code from the output of the switch 12 to the matrix display panel. Impulse installation frequency binary counter

the matrix display panel 6 and on a command that is also received from the control unit 7, the memory unit will output the following encoded ordinate value, which will set the reversible counter 4 to the corresponding state. The pulses of the pulse will be fed to the input of the binary counter 8 and through the element And 10 to the input of the reversing
