Description
Technical field:
The utility model relates to a kind of infrared electro checkout gear, belongs to photoelectric detection system technical field in the chemical fibre spinning production.
Background technology:
The technical scheme of the circuit wire sensor that existing chemical fibre spinning equipment FDY long filament production line is used is: the side at silk thread is provided with a pair of infrared emission in a certain angle and infrared receiving diode, silk thread vibrates near the intersection point of infrared emission and infrared receiving diode angle, the infrared ray organizine line reflection of infrared-emitting diode emission is given infrared receiving diode, because silk thread vibrates near intersection point, thereby infrared receiving diode obtains a strong and weak infrared signal that changes, Gu with the foundation of this infrared signal that changes fracture of wire as whether.Because the silk thread diameter is very thin in the actual production, and there is the influence of 50Hz lighting source in the workshop again, so on the one hand the amplification quantity of circuit wire sensor amplifier since be subjected to that the influence of workshop 50Hz mains lighting supply can not do too high, on the other hand owing to be subjected to the restriction of infrared-emitting diode rated current, the electric current of its infrared-emitting diode can not strengthen arbitrarily, add that the environment temperature in the FDY long filament workshop is higher, the duty of its circuit wire sensor photodiode all is under the maximum conditions and uses, thereby has shortened its service life greatly.
Summary of the invention
The utility model purpose is to provide that a kind of highly sensitive, antijamming capability is strong, a kind of infrared fracture of wire induction installation of long service life.
The technical solution of the utility model is: be made up of housing, infrared-emitting diode and infrared receiving diode, be provided with an infrared-emitting diode and at least two infrared receiving diodes in the housing, two infrared receiving diode cocurrent and parallels are placed, and infrared-emitting diode and infrared receiving diode are in a certain angle.
Other technical characterictic of the present utility model is the infrared receiving diode performance parameter basically identical that two cocurrent and parallels are placed, and wherein the axle center of an infrared receiving diode is any in the same way parallel placement of axis.
Because the infrared diode cocurrent and parallel of two or two above performance parameter basically identicals is placed, thereby they are except that the infrared signal difference of the silk thread vibration that receives, other lighting source interfering signal from all directions 50HZ is the same substantially, thereby after the signal subtraction with two or two above infrared receiving diodes, just can remove interfering signal, obtain pure sense silk signal, this has just improved the sensitivity and the antijamming capability of induction installation, thereby can significantly improve the circuit multiplication factor, also can reduce the operating current of infrared-emitting diode simultaneously, the speed of its light decay has been slowed down; Owing to improved the multiplication factor of circuit, under the situation that infrared receiving diode decays at the same rate, also prolonged its service life relatively.
The utility model has the advantages that reasonable in design, the induction sensitivity height, antijamming capability is strong, long service life.

The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment one
As shown in Figure 1, 2, 3, with housing 4 in establish an infrared-emitting diode 1 and two infrared receiving diodes 1, infrared receiving diode 23 on the same plane, infrared receiving diode 1, infrared receiving diode 23 cocurrent and parallels are also placed at homonymy, the axis of infrared-emitting diode 1 and two infrared receiving diodes is in a certain angle, two infrared receiving diode 1, infrared receiving diode 23 performance parameter basically identicals that cocurrent and parallel is placed.
Embodiment two
Shown in Fig. 4,5, be positioned over infrared-emitting diode 1 both sides at housing 4 interior two infrared receiving diodes 1, infrared receiving diode 23 cocurrent and parallels, infrared-emitting diode 1 is in a certain angle with infrared receiving diode 1, and two cocurrent and parallels are positioned over the infrared receiving diode 1 of infrared-emitting diode 1 both sides, the performance parameter basically identical of infrared receiving diode 23.
Embodiment three
Be to be provided with infrared-emitting diode 1 and infrared receiving diode 1 in the same way on the same horizontal plane in the housing 4, infrared receiving diode 23 cocurrent and parallels are positioned over the below of infrared receiving diode 1, and infrared-emitting diode 1 and infrared receiving diode 1, infrared receiving diode 23 are in a certain angle.Two infrared receiving diodes 1 that cocurrent and parallel is placed, the performance parameter basically identical of infrared receiving diode 23.
After two infrared receiving diodes 1 of performance parameter basically identical, the signal subtraction of infrared receiving diode 23, just can remove interfering signal, obtain pure sense silk signal.When the infrared ray organizine line reflection of infrared emitting diode 1 emission changes for the infrared signal power of infrared receiving diode 1, whether then can detect fracture of wire.
