The signal receiving device that also comprises the optical signal that receives the light-emitting device transmission.
Signal receiving device shown in Fig. 2,3,4, it comprises housing 3, and housing 3 front panels 31 are provided with light inlet window 32, and light inlet window 32 places are equipped with light-passing board 33; Be provided with support 4 in the housing 3 with cavity (not shown), support 4 front ends are provided with 11 cylindrical mirrors that are arranged in order 5 (511,512,513 ... 521), with cylindrical mirror 516 is the benchmark cylindrical mirror, and all the other cylindrical mirrors all have an acute angle angle with benchmark cylindrical mirror 516.With benchmark cylindrical mirror 516 is the center, and all the other cylindrical mirrors are symmetricly set in benchmark cylindrical mirror 516 both sides.As shown in Figure 5, cylindrical mirror 517 and cylindrical mirror 515 are respectively with 516 one-tenth 1.5 ° of angles of benchmark cylindrical mirror and be symmetricly set in benchmark cylindrical mirror 516 both sides; Cylindrical mirror 518 and cylindrical mirror 514 are respectively with 516 one-tenth 3.5 ° of angles of benchmark cylindrical mirror and be symmetricly set in benchmark cylindrical mirror 516 both sides; Cylindrical mirror 519 and cylindrical mirror 513 are respectively with 516 one-tenth 6 ° of angles of benchmark cylindrical mirror and be symmetricly set in benchmark cylindrical mirror 516 both sides; Cylindrical mirror 520 and cylindrical mirror 512 are respectively with 516 one-tenth 9 ° of angles of benchmark cylindrical mirror and be symmetricly set in benchmark cylindrical mirror 516 both sides; Cylindrical mirror 521 and cylindrical mirror 511 are respectively with 516 one-tenth 13 ° of angles of benchmark cylindrical mirror and be symmetricly set in benchmark cylindrical mirror 516 both sides.As wherein the angle of the cylindrical mirror of a side and benchmark cylindrical mirror 516 is for just to be positioned at benchmark cylindrical mirror 516, it is negative then being positioned at the cylindrical mirror of benchmark cylindrical mirror 516 opposite sides and the angle of benchmark cylindrical mirror.
The skew of weft angular range that detects of the present utility model like this is-13 °～+ 13 °, and the angle between 10 cylindrical mirrors and the benchmark cylindrical mirror 516 can be according to actual instructions for use setting.The sectional view of cylindrical mirror as shown in Figure 6, it is one to have the cuboid cylindrical mirror of arcwall face.
Support 4 rear ends are provided with slit plate 6.As shown in Figure 7, slit plate 6 is provided with and cylindrical mirror 5 corresponding 11 slits 7 (711,712,713 ... 721), every slit is all corresponding to a cylindrical mirror.Article 11, the width L of slit is all identical, and the visual actual instructions for use of its concrete numerical value is determined.
Also be provided with circuit board 8 in the housing 3.As shown in Figure 8, circuit board 8 is provided with 11 row photoelectric sensors 9 (911,912,913 ... 921) and the control circuit (not shown).Circuit board 8 be arranged on after the slit and photoelectric sensor corresponding with slit, housing 3 rear ends are equipped with display screen 10, display screen 10 is connected with control circuit on the circuit board 8.Photoelectric sensing 9 can adopt silicon photocell.
Operation principle of the present utility model is: the corresponding setting with signal receiving device of light-emitting device, the infrared ray signal that light-emitting device sends is after 11 cylindrical mirrors focus on, pass 11 slits respectively and be incident upon on 11 photoelectric sensors, 11 photoelectric sensors are converted to optical signal respectively and corresponding 11 road signals of telecommunication of light signal strength.Control circuit compares its power after receiving this 11 road signal of telecommunication, and chooses a road the highest signal of telecommunication of intensity, and display is shown and this strongest corresponding numeral of the road signal of telecommunication.For example represent 11 cylindrical mirrors (521,520,519 with numeral 5,4,3,2,1,0 ,-1 ,-2 ,-3 ,-4 ,-5 respectively ... 511).
During use, fabric does not stop to move between light-emitting device and signal receiving device, so that parallel constantly cuts the optical signal that light-emitting device sends.Parallel can stop infrared signal, and the slit between two parallels can allow infrared signal to pass.Make benchmark cylindrical mirror 516 horizontal positioned.When having skew of weft, the slit between two parallels also is oblique.Along with the motion of parallel, the infrared light that passes every slit all can see through 11 cylindrical mirrors successively and form 11 road signals of telecommunication.When the slit parallel with one of them cylindrical mirror or the most approaching when parallel, the optical signal that then sees through this cylindrical mirror is the strongest, the signal of telecommunication is also the strongest with producing on this cylindrical mirror corresponding photoelectric sensor, through control circuit relatively after, make display show one with the corresponding numeral of this road photoelectric sensor.
As to see through the signal of telecommunication that horizontally disposed benchmark cylindrical mirror 516 produces when the strongest on photoelectric sensor 916, the numeral of its correspondence of demonstration is 0 on the display screen.When the signal of telecommunication that produces as photoelectric sensor 917 was the strongest, display showed that the numeral of its correspondence is 1; When the signal of telecommunication that produces as photoelectric sensor 915 was the strongest, display showed that the numeral of its correspondence is-1, and the rest may be inferred.
When not existing skew of weft to be the equal level of parallel, two parallels pass through cylindrical mirror 521,520 successively ... 511.Infrared light passes two slits between the parallel and forms 11 road optical signals successively and be incident upon formation 11 road signals of telecommunication on corresponding 11 photoelectric sensors separately.Because the slit between two latitudes is parallel with benchmark cylindrical mirror 516, therefore the signal of telecommunication that forms on photoelectric sensor 916 during through benchmark cylindrical mirror 516 when two parallels is the strongest, through control circuit relatively after, it is digital 0 that display is shown, represents not have skew of weft.
When there being skew of weft, and the parallel gradient is when being 3.5 °, and the infrared light that then passes cylindrical mirror 518 is the strongest.The signal of telecommunication that forms on photoelectric sensor 918 is also the strongest, and control circuit makes display show that numeral is 2, and its expression skew of weft gradient is 3.5 °.
Therefore, when the user sees digital that display screen shows, can judge it is that infrared light through which cylindrical mirror is the strongest, just can judge also how many skew of weft gradients is according to shown numeral.
Front end in the utility model, rear end are that the transmission sequence with optical signal is as the criterion, and front end receives optical signal earlier, receives optical signal behind the rear end.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
