Description

The direct separation type laser vessel of a kind of non-level passive semi rudder angle position sending set

Technical field:

The utility model relates to position, angle sending set, position, particularly a kind of rudder for ship angle sending set.

Background technology:

The rudder for ship instrument is the prerequisite instrument and equipment of all size boats and ships that navigates by water on the water, the rudder for ship instrument is to show the rudder for ship position according to the information of position, rudder for ship angle sending set, position, rudder for ship angle sending set is the link gear that keeps synchronous parallel principle by a kind of opposite side of parallelogram at present, devices such as drive such as potential device, Hall element, adjustable condenser, rotary encoder and rudder for ship rotate synchronously, these devices can produce the numerical value change of magnetic, electricity, pulse etc. when rotating, utilize the changing pattern of these numerical value to draw up the angle that rudder for ship changes.

This way exists that transmission distance is little, outside the poor anti-interference, problem easy to wear, also exist:

1, even the very accurate link gear of doing, unavoidable accumulated error and conduction eror, precision is difficult to reach 0.1 degree.

2, these devices are not to be position, angle sensing design-calculated specially, and the linearity of numerical value change is imperfect, is difficult to accurately simulate the position, variation angle of rudder for ship.

3, because these devices are not the data that direct reading angular changes, neither produce operable digital code information, but analog signal conversion is become digital signal, not only to influence precision, and influence the single-piece response time.

4, the checking for zero difficulty, though the detection of steamer rudder angle, substantially be not more than 180 the degree, but need to determine zero-bit, existingly be used for the senser element that the position, angle is detected, rotations that can 360 degree, but detections that all can not 360 degree except rotary encoder, the blind area that a numerical value is arranged, the many troubles of definite increase of zero-bit are given in the blind area of this numerical value.

Chinese patent 2007101713839 proposes a kind of information generator of ship rudder instrument from dynamic correction, the analog information that rudder for ship rotates can be become digital code information and go out.But still can not overcome above-mentioned defective.

Summary of the invention:
