SU219297A1 - DEVICE FOR MEASUREMENT, REGISTRATION AND CLASSIFICATION OF WIND SPEEDS AND DIRECTIONS - Google Patents

Description

The present invention relates to the field of meteorological instrumentation.

The known devices for measuring, recording and classifying wind speeds and directions, which contain wind speed and direction receivers connected through converters to a group of recorders and indicators, do not allow to increase the accuracy of measurements and automatically classify speeds and winds according to specified gradations.

The proposed device substantially eliminates the indicated disadvantages. This is achieved by the fact that in it the groups of recorders and indicators are interconnected in series in parallel.

The drawing shows the block diagram of the described device.

The device contains a receiver / wind speed associated with a pulse converter 2, whose pulses with a frequency proportional to the measured speed are received in blocks 3 and 4, where they are integrated and at the end of each time interval specified by pulsator 5 are output as an average value to the corresponding cell of the decoder 6 from where they are fed to the electronic switch 7 and the repetition recording unit 8.

a pulse is given to record a point corresponding to an average wind speed. This recording is kept on the tape of the medium speed recording unit 9, whose drum by the stepping motor is rotated at the end of each time interval by one division.

The operator at any time using the display unit 10 can visually determine the number of cases of repetition of various values of average wind speed. The number of cases of repeated wind speeds remembered in block 8 is simultaneously perceived by speed repeat averaging block 11. Signal from the block

11 enters block 12 of recording the wind speed repeatability distribution curve. Simultaneously with the registration of wind speeds, its direction is also recorded. Receiver 13 direction, made

for example, in the form of a wind vane, together with the transducer M produces pulses, the amplitude of which is proportional to the direction of the wind. Next, the pulses arrive at the block / 5, where they integrate and at the end of each time interval specified by the pulser 5 are outputted in average value to the corresponding cell of the decoder 16, from where they arrive at the repeat block 17. Operator B at any time using the block of cases of the repetition of various values of the average wind direction.

Subject invention

A device for measuring, recording and classifying wind speeds and directions, comprising receivers of wind speed and direction associated with converters with a group of recorders and indicators, characterized in that, in order to improve measurement accuracy and automatic classification of wind speeds and directions, according to predetermined gradations , in it the groups of recorders and indicators are interconnected in series-parallel.
