Description

one

This invention relates to conversions. analogue code and can be used in automation and electrical engineering, in particular, to measure meteorological visibility. The known converter is an angle-code that contains an angle sensor, a tripper, the output of which is connected to one of the inputs of the first And element connected to the input of the counter, the second element And, the reset circuit

and the decoder.

The purpose of the invention is to improve the reliability of the device and its speed.

This is achieved by introducing voltage-frequency converters into the angle-code converter, the inputs are connected to the output of the angle sensor, and the outputs are connected to the inputs of the AND elements, another input of volts (of the AND element connected to the trigger output, the input of which is connected to the output counter, one voltage-frequency converter with a linearly increasing function is filled with a characteristic that is directly proportional to the parameter being measured, and

(A voltage-frequency converter with a linearly decreasing function is made with a characteristic inversely proportional to the parameter being measured.

The drawing shows the block diagram of the proposed Converter angle code.

It contains the angle sensor 1, the converter is the same as the frequency-frequency 2 with a linearly increasing function with a proportional dependence on the input signal, the converter is directly a frequency 3 with a linearly decreasing function with inverse proportion to the input voltage, elements 4 and 5, binary counter 6 and trigger 7.

The signal from the output of the angle sensor is fed to the inputs of the converters; cc-frequency 2 and 3. The output of converter 2 is connected to the input of the element I, and converter 3 to the input of sfleh ema AND 5. The second inputs of the elements And are connected to the trigger output. The output element And 5 is connected to the input of a binary counter, the output of which is connected to the input of the trigger. The device is started at the second trigger input. The output of the element R 4 is the output of the device. The principle of the operation of the angle-code converter is as follows. The voltage of the yes-iv angle, proportional to the parameter being measured, is applied to the voltage-frequency converters. Converter 2 generates a frequency that is linearly increasing from the input parameter. Converter 3 generates a frequency linearly decreasing from the input parameter. At the command, the triggering trigger changes the whole and opens the elements I. Through the open element I 5, the pulses from the output of the converter 3 are fed to the counter. At the same time from the output of the Converter 2 through the element And 4 pulses arrive at the output of the device. The i-shul repetition from the output of the counter returns the trigger to the original one, closing the elements I. At this the conversion cycle ends.

Thus, at the output of the transform (the angle-code body produces a number of pulses proportional to the measured angle.
