Description

The invention relates to digital measuring equipment, automation, computer technology and information display tools and can be used to display parameters of 5 radio engineering devices, systems and complexes (radar, sonar, automated control systems, etc.) on the screen of a standard cathode ray tube (CRT) embedded control equipment.

The purpose of the invention is to simplify the device, reducing the range for. available property and instruments and improving the working conditions of the operator with the front panel of the built-in control equipment by displaying all measured parameters on the screen of a standard cathode ray tube.

The drawing shows a diagram of the device 20.

The circuit contains a measurement unit 1, an analog code converter 2, a first counter 3, an OR element 4, a second counter 5, a second decoder 6, a key block 7, a first decoder 8, an indication unit 9, a delay element 10, an AI element.

The device operates as follows.

The functioning process is divided into three stages: measuring a parameter, converting the value of this parameter into a sequence of pulses, which is recorded in the first counter; display of the measurement result.

The measured parameter in the form of a voltage level or a time interval, etc. from the measuring unit 1, an analog code is supplied to the input of the converter, in which it is converted into a pulse sequence, which is fed to the counting input of the first counter Z. This counter is previously! __ 45 is reset to zero (not shown) "

After the registration process of the measured parameter in the counter 3 from block 1 receives a signal that passes through the element OR 4 and resets the second counter 5 to zero. This determines the choice of the first output bus of the second decoder 6, thereby achieving the connection of the first four output buses of the counter 3 - 55

cut block 7 keys to the inputs of the first decoder 8, the number of which is four. This ensures the selection of one of ten (by the number of digits 0, 1, 2 ,, .. 9) output buses of the decoder. This, in turn, ensures the formation of a voltage indication unit 9 and

Uy (Н and backlight pulses U _z (t!, Under the influence of which the corresponding digit of the decimal number is displayed on the CRT screen.

The indication block 9 is triggered by a signal coming from block 1 through the delay element GO, in which this signal is delayed for the duration of the transfer processes in the counter. unit 9 produces a signal U _n (11 which is fed to the count input of the counter 5 and the contents of this counter is incremented by one, thus achieving a connection unit 7 through the following four key counter 3 to the outputs of the decoder output lines 8 and, consequently, the display the next character on the CRT screen. This process is repeated until? long as the symbol is displayed, the last digit being played on the CRT screen of a decimal number, that is, when will select the last decoder output bus 6. In this case, • U _n signal (t) from the output of block 9 passes through the element And 11 k 'resets the counter 5 to 0. The process of displaying the number on the CRT screen is repeated until the counter 3 is reset to zero (not shown). The display of the measured parameters on the screen of a standard CRT equipment built-in control improves the working conditions of the operator with such indicator equipment, reduces its fatigue, which reduces the likelihood of erroneous reading of data reproduced on the front panel of such equipment. In addition, the display of the parameters of the radio components and units on the CRT screen reduces the range of spare equipment and devices, which is especially important in ship conditions.
