Fig. 4 shows the luminance meter operation schematic diagram of the utility model one embodiment.The Fig. 4 illustrates luminance meter 102
Simple Dynamic schematic diagram, visual angle is consistent with the view directions of Fig. 2, and X-axis is horizontal direction, and Y-axis is vertical direction, X-axis, Y
Plane where axis is parallel with 109 surface of luminous object.First output shaft axis of the 5th electric machine assembly 108 in the Y-axis direction,
The axis of 4th output shaft of four electric machine assemblies 107, the third output shaft of third electric machine assembly 105 and luminance meter 102 is vertical
In drawing, and the 4th output shaft of the 4th electric machine assembly 107 passes through O point, and the O point is as origin.Under original state or to return
In the state of zero position, third the output shaft crossing point F ', the axis passing through point G ' of luminance meter 102 of third electric machine assembly 105.Hold
Intelligible, line segment OF ' is equal to the 4th output shaft to the distance of third output shaft, is roughly equivalent to the length of the first pivoted arm 106,
Line segment F ' G ' is equal to third output shaft to the distance of 102 axis of luminance meter.In the initial state, the first pivoted arm 106 is perpendicular to X
Axis, line segment OF ' and F ' G ' are superimposed in the height direction, and luminance meter 102 is made to be in highest order.If the luminous object to be detected
The normal crossing point G of 109 light emitting source, then using the 4th output shaft of the 4th electric machine assembly 107 as origin, 102 axis of luminance meter
Line will move on to point G from point G ', and third output shaft axis needs are accordingly moved to point F from point F '.Specifically, luminance meter is connected
The line segment OG of 107 axis of 102 axis and the 4th electric machine assembly and X-axis angle are A, and the angle with line segment OF is B, line segment OF with
The angle of line segment FG is C, and the two supplementary angle is D, and line segment OF and Y-axis angle are E.To make 102 axis of luminance meter from the point of view of zero position
Demand goes out the angular dimension of angle E and D when line goes to location point G, i.e., the 4th output shaft of the 4th electric machine assembly 107 is with respect to Y
Axis turns over angle E, and third output shaft axis is made to be moved to point F from point F ', and then third output shaft is relative to line segment OF angle of rotation
D is spent, 102 axis point of arrival G of luminance meter is made.As previously mentioned, when luminous object 109 is plane, so that it may which five axis are rotated letter
Turn to two axis rotation, in 102 axis of luminance meter perpendicular to 109 surface of luminous object when, simultaneously or sequentially start the 4th electricity
Thermomechanical components 107 and third electric machine assembly 105 can make 102 axis of luminance meter mobile on 109 surface of luminous object, to be directed at hair
Specific light emitting source on light object 109.
With reference to Fig. 4, if the length of line segment OG is a, the length of line segment OF is b, and the length of line segment FG is c, and line segment OG is in X-axis
On projected length be d, projected length in Y-axis is e, and the coordinate of point G is (d, e).It is obtained by Pythagorean theorem: a2=d2+e2。
It is obtained by sine: tanA=e/d, A=arctan e/d.It is obtained by the cosine law: a2=b2+c2- 2bccosC, cosC=
(b2+c2-a2)/2bc, then C=arccos (b2+c2-(d2+e2))/2bc.It is obtained by the cosine law: c2=b2+a2-2ab·cosB,
CosB=(b2+a2-c2)/2ab, then angle B=arccos (b2+(d2+e2)-c2)/2b(d2+e2)1/2Final: angle D=
180°-arccos(b2+c2-(d2+e2))/2bc.E=90 ° of-A-B.E=90 ° of-arctan (e/d)-arccos (b2+(d2+e2)-
c2)/2b(d2+e2)1/2.So using the 4th output shaft axis of the 4th electric machine assembly 107 as origin, when input point in the controller
When coordinate (d, e) of G, E, the angular dimension of D are calculated by above-mentioned formula, and control the 4th of the 4th electric machine assembly 107
The third output shaft of output shaft and third electric machine assembly 105 turns over the angle E and the angle D respectively, completes 102 axis of luminance meter and goes to point G
