Description

Wind direction indicator

Technical Field

The embodiment of the utility model provides a wind direction detection technology especially relates to a anemoscope.

Background

The anemoscope has the function of measuring the wind direction. Wind direction values are usually obtained from differences in the effect of the air flow in different directions.

In the prior art, a mechanical anemoscope indicates a wind direction according to a swing direction of a wind vane, an ultrasonic anemoscope calculates the wind direction according to vector values of two or more groups of wind speeds, and a wind pressure sensor judges the wind direction according to pressure differences in different directions. In any sensor type, a bow mark is usually set, and the mark is installed in a direction directly ahead of the ship. And calculating a wind direction value according to the deviation of the actual wind direction and the azimuth. Considering that the direction of the bow of the ship is not fixed during the navigation of the ship, the ship is matched with a due north azimuth indicator. Thus, the measured deviation between the wind direction relative to the ship bow and the ship bow relative to the due north direction can be subtracted to obtain the wind direction relative to the due north, namely the true wind direction.

The problems of setting the bow mark are as follows: the installation precision requirement is higher, and the debugging process is long. If the bow mark deviates from the bow, the measured wind direction always deviates, and the solution can only be to finely adjust the angle of the wind direction sensor until the measured wind direction is correct. The foreship mark needs to be striking, sun-proof, rain-proof, salt fog-proof and the like, and the manufacturing process has higher complexity and higher cost.

As shown in fig. 4, the calculation principle of the wind direction detection method is explained as follows:

the bow marks the direction and is the zero position relative to the wind direction. The angle of the clockwise deviation from the actual bow direction is set to be beta. When there is no deviation, β is 0.

The current bow direction is the angle of the clockwise deviation between the current bow direction and due north, and is set as sigma, and when the bow points to due north, the sigma is 0.

The measured wind direction: wind direction relative to the bow marker, denoted by φ;

relative wind direction: and the wind direction value when the current bow direction is zero degree is expressed by R.

When the bow mark points to the bow, the relative wind direction R is equal to phi;

when the bow mark is not pointed to the bow, the clockwise deviation between the bow mark and the bow is beta, and the relative wind direction R is phi-beta.

True wind direction: the value of the wind direction when the north is zero degree is represented by T.

When the bow points to the north, T is R.

When the bow is inconsistent with the due north, the clockwise deviation of the bow from the due north is sigma, and T is R-sigma.

The wind direction is determined as follows:

the host is set to be in a self-checking mode;

the CPU reads the numerical value M of the bow mark relative to the due north direction, wherein M is sigma + beta;

the host reads the current bow orientation sigma;

the CPU calculates the difference between M and sigma, M-sigma, (sigma + beta) -sigma, beta;

the CPU stores the correction value delta;

the host is set to be in a working mode;
