The another kind icing photoelectric sensor schematic diagram that Fig. 2 provides for the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to the one icing photoelectric sensor schematic diagram that Fig. 1, Fig. 1 provide for the embodiment of the present invention.
In a kind of detailed description of the invention, it is provided that a kind of icing photoelectric sensor, including: it is used for launching ultrared described infrared transmitting tube 101; For described infrared ray is transmitted the described launch tube 102 to ice sheet 105 from described infrared transmitting tube 101; At least one is for receiving the described photoelectric receiving tube 104 of the reflected ray through the reflection of described ice sheet 105; For the described reception conduit 103 by described reflected ray transmission to described photoelectric receiving tube 104; Wherein, the ice sheet 105 of described reception conduit 103 described housing all relative to described launch tube 102 tilts, and has therebetween predetermined angle. Icing photoelectric sensor operation principle is: when ice photoelectric sensor top layer does not have ice sheet 105 to cover, infrared light is produced by infrared transmitting tube 101, directly penetrates through launching light pipe, and photoelectric receiving tube 104 does not receive any icing information. And when there being ice sheet 105 to cover, part infrared light is reflected by ice sheet 105, along with the increase of ice thickness, the reflection light of diverse location can be gradually increased, and calculates ice covering thickness according to the difference reflecting light that multiple photoelectric receiving tubes 104 receive. Adjust and launch light pipe and the nearest predeterminable range scope received between light pipe, can be achieved with the detection of different minimum icing thickness, adjust and receive light pipe and the farthest predeterminable range scope launching light pipe, achieve that the detection of different maximum icing thickness, it is achieved that the detection of an a wide range of icing range.
Owing to there is predeterminable range between described photoelectric receiving tube 104 and described infrared transmitting tube 101, therebetween distance adjustable, therefore, the infrared ray sent from infrared transmitting tube 101 is incident to ice sheet 105 through launch tube 102, the photoelectric receiving tube 104 of distance infrared transmitting tube 101 predeterminable range is reflexed to through ice sheet 105, ice sheet 105 Infrared of different-thickness through ice sheet 105 reflection back reflection to the place of infrared transmitting tube 101 different distance, in the place of different distance, photoelectric receiving tube 104 is set, it is thus possible to change the range of sensor, the icing detection of wide range can be realized.
Further, in order to reduce the volume of icing photoelectric sensor, in above-mentioned icing photoelectric sensor, described photoelectric receiving tube 104 is arranged in the same plane relative with described ice sheet 105 with described infrared transmitting tube 101.
Further, in order to improve the accuracy of measurement, the predetermined angle between described reception conduit 103 and described launch tube 102 is preferably 90 ��. It is to be noted, launch light pipe and receive each own certain draft angle of light pipe, reason is if launching light pipe and being set to ice sheet 105 angle be 90, the infrared ray launched major part after ice sheet 105 reflects enters into again in transmitting light pipe, cause that range is only small maybe cannot measure, therefore launch light pipe and receive light pipe own certain draft angle each relative to ice sheet 105, draft angle can be 30 degree or 45 degree or 60 degree, and this draft angle can change in the angular interval of 10 degree to 90 degree.
Further, as it is shown in figure 1, in above-mentioned icing photoelectric sensor, described photoelectric receiving tube 104 includes: the first photoelectric receiving tube 104, itself and described infrared transmitting tube 101 have the first predeterminable range; Second photoelectric receiving tube 104, itself and described infrared transmitting tube 101 have the second predeterminable range; Wherein, described first predeterminable range is less than described second predeterminable range.
Concrete, photo-electric freezing sensor includes 101, two photoelectric receiving tubes 104 of an infrared transmitting tube, respectively the first photoelectric receiving tube 104, second photoelectric receiving tube 104, what be connected with the first photoelectric receiving tube 104 is the first reception light pipe, first receives the light pipe other end is connected with ice sheet 105, what be connected with the second photoelectric receiving tube 104 is the second reception light pipe, second receives the light pipe other end is connected with ice sheet 105, first to receive light pipe parallel with the second reception light pipe, all be transmitted into light pipe and become a predetermined angle. Two photoelectric receiving tubes 104 arrange successively, and the first photoelectric receiving tube 104 and No. second photoelectric receiving tube 104 all receive the infrared light being reflected back from ice sheet 105, obtain icing information, calculate ice sheet 105 thickness. Along with ice sheet 105 grows out of nothing, from thin thickening change procedure, the signal of the first photoelectric receiving tube 104 first strengthens weak gradually again or tends to constant, the signal of the second photoelectric receiving tube 104 strengthens in certain thickness ice sheet 105 scope always, according to the signal that this first photoelectric receiving tube 104 and the second photoelectric receiving tube 104 receive, namely can determine whether whether freezing sensor top layer freezes and icing thickness.
It is to be noted, the quantity of photoelectric receiving tube 104 includes but not limited to two, when photoelectric receiving tube 104 is three, distance between 3rd photoelectric receiving tube 104 and infrared transmitting tube 101 is more than the second predeterminable range, the signal received is mainly used in carrying out difference with front two-way, removes the interference of the factors such as environment light. Other all consistent with above-mentioned situation, does not repeat at this.
It is pointed out that the quantity of photoelectric receiving tube 104 includes but not limited to two, the quantity of photoelectric receiving tube 104 is more many, measures more accurate.
Further, in above-mentioned icing photoelectric sensor, described launch tube 102 and described reception conduit 103 are optical fiber.
Further, in above-mentioned icing photoelectric sensor, described launch tube 102 and described reception conduit 103 are glass tubing.
It is pointed out that described launch tube 102 and described reception conduit 103 include but not limited to optical fiber, glass tubing, it is also possible to for ultrared metal catheter etc. can be transmitted, as long as guaranteeing transmission infrared ray, all within protection domain.
The present invention also provides for a kind of icing measurement apparatus, including transmission line simulation, also includes the icing photoelectric sensor being connected with described transmission line simulation described in any of the above-described item. The transmission line of electricity inconvenience to be measured due to scene is directly connected to icing photoelectric sensor, therefore, be connected icing photoelectric sensor at one section with on the same or analogous transmission line simulation of transmission line of electricity to be measured, its measurement result with directly measure the identical of transmission line of electricity to be measured.
Icing photoelectric sensor provided by the invention is installed on transmission line simulation, and light structure is simple, and anti-interference is good, range is big, it is capable of identify that ice type, range can be changed by adjusting the distance launched between light pipe and reception light pipe, it is possible to achieve the icing detection of wide range.
