Detailed description of the invention
Below in conjunction with the accompanying drawings and be embodied as that the invention will be further described.
The structure of present invention sun tracker based on fiber array is as shown in Figure 1, Figure 2 and Figure 3:
A kind of sun tracker based on fiber array is by collecting lens module 1, fibre bundle module 2, photosensitive
Audion illuminant module 3, wire 4 and micro-control module able to programme 5 form.
The structure of the most each parts:
1.1) described collecting lens module 1 by convex lens 1-1, light collecting barrel 1-2, fibre bundle array 2-1,
Module base 1-3 is constituted.
1.2) described fibre bundle module 2 is to be made up of fibre bundle 2-2, and they are arranged in fibre bundle array 2-1
Apperance.

Pipe 3-2, snap ring 3-3, phototriode interlayer 3-4, optical fiber interlayer 3-5 and optical fiber 2-2.
The annexation of the most each parts
Described collecting lens module 1 is connected with described fibre bundle module 2, and ensures what fibre bundle was arranged in
Fibre bundle array 2-1 is centrally located at the center of base 1-3 in described collecting lens module 1.Described poly-
Light cylinder 1-2 is fixed on above module base 1-3, it is ensured that when light collecting barrel is entered in sunlight direct projection, described convex lens
The luminous point that 1-1 assembles falls in the center of fibre bundle array 2-1.
Fibre bundle 2-2 in described fibre bundle module 2 and described phototriode illuminant module 3 pass through snap ring
3-3 connects, and the signal of telecommunication of phototriode (3-2) is by connected phototriode lead-in wire 3-1
Transmitting, fibre bundle 2-2 is the most right with phototriode 3-2 simultaneously, it is ensured that phototriode is the most photosensitive.Card
Ring 3-3 blocks immovable in phototriode interlayer 3-4.
Phototriode lead-in wire 3-1 is connected with micro-control module 5 able to programme, and connected mode uses general key
Dish scan mode.
The present invention is embodied as, and step is as follows:
First, the fibre bundle array 2-1 in Fig. 2 to be carried out quadrant division, take fibre bundle array 2-1
Center, as coordinate points O, is crossed this point simultaneously and is made a coordinate system, be divided into by fiber array 2-1
Four quadrants, and set initial coordinate values to optical fiber in each quadrant.Then by collecting lens module 1
It is arranged on and needs on the vertical device following the tracks of the sun so that device needs to Y when luminous point falls below X-axis
The motion of axle positive direction adjusts, and when luminous point falls above X-axis, device needs to adjust to the motion of Y-axis negative direction,
When luminous point falls in Y-axis left, device needs to adjust, when luminous point falls in Y-axis right to the motion of X-axis positive direction
Time device need to X-axis negative direction motion adjust.
