Description

(54) ОПТОЭЛЕКТРОННЫЙ ДАТЧИК ПОЛОЖЕНИЯ СВЕТЯЩЕГОСЯ ОБЪЕКТА(54) OPTOELECTRONIC SENSOR OF POSITION OF LUMINATING OBJECT

Изобретение относитс кThe invention relates to

контрольно из-control iz-

мерительной технике, в частности к констру цйи оптоэлектронных датчиков положени свет щихс объектов.measuring equipment, in particular, to the design of optoelectronic sensors for the position of luminous objects.

Известен датчик положени свет щегос объекта, в котором контролируемый объект проектируют на входной торец волоконно-оп тического преобразовател l. Волокна преобразовател во входном торце уложены в виде пр моугольной матрицы, каждыйA known position sensor is a light object, in which a monitored object is projected onto an input end of a fiber optic converter l. The transducer fibers at the input end are arranged in a rectangular matrix, each

жгут матрицы соответствует одному из элементов изображени контролируемого объекта , а количество элементов в контролируемом поле достигает Юthe matrix harness corresponds to one of the image elements of the object being monitored, and the number of elements in the controlled field reaches 10

Недостаток известного датчика заклк. чаетс в технологической сложности изго товлени матрицьг.The disadvantage of the known sensor zaklk. It is in the technological complexity of the manufacture of matrices.

Наиболее близким по технической сущ- кости к предлагаемому изобретению вл етс датчик положени свет щегос объекта, содержащий объектив, волоконно-оптическое кодирующее устройство и фотоприемники M.The closest to the technical essence of the present invention is a position sensor of a light of a grounded object, comprising a lens, a fiber optic encoder, and photodetectors M.

Волоконно-оптическое кодирующее устройство состоит из большого числа жгутов, The fiber optic encoder consists of a large number of harnesses,

каждый разделен на выходном торце на несколько пучков, количество которых от числа единиц двоичного кода. На входном торце жгуты уложены вплотную друг к другу, а пр моугольный растр так, что каждый жгут соответствует одному из элементов изображени контролируемого объекта, а на выходном торце нучки волокон этих жгутов разведены по фотоприём ,нйкам двоичного кода.each is divided on the output end into several beams, the number of which is from the number of binary code units. At the input end, the harnesses are laid close to each other, and the rectangular raster so that each bundle corresponds to one of the image elements of the object being monitored, and at the output end of the fiber knob, the fibers of these bundles are separated according to a photo-receiver, a binary code.

Однако известный датчик имеет сложную конструкцию за счет большого количества жгутов, число которых определ етс размерами контролируемого объекта |И точностью измерени .However, the known sensor has a complex structure due to the large number of harnesses, the number of which is determined by the size of the object being monitored and the accuracy of the measurement.

Цель изобретени - упрощение конструк- щии датчика.The purpose of the invention is to simplify the design of the sensor.

Claims

To do this, in the proposed sensor, the photodetectors are annular, e. the end of the fiber-optic encoder is made in the form of a rotating disk with the light-guide harnesses laid on it in the form of a straight line, which at the output end of the fiber optiTenecxoro clump up the device in the form of an EOEaustricon ring, In the drawing there is a pin on the head of a stitched shaft, in the form of an EOEaustricon rings, With an electronic position sensor, the light of the object's object is contained in a fiber optic encoder 1 of the photocurrent 2 and lens 3. The input current and voltage of the encoder is rotatable from the engine 4 of the disk 5, with a light laid in it in the guide. cable harness 6. At the exit end of the coding device 1, the light-conducting harness 7 is laid in the air curtain. The rings opposite the co-mounts are still mounted the Koldeva photo traps 2 bits of the binary coy. of the harnesses l is divided into several beams, the copy of which is dependent on the only binary code equal to the number of this bundle. The movable part of the sensor is made in the form of a truncated cone planted on the hemming of the 8 and rotated from the engine 4. The sensor works as follows. The image of the light object is projected onto the horizontal plane of the diode 5 in the form of a point source of light. 6, the image of the object under test at the output of the annular photodetectors 2 appears in the binary code 9 information about the coordinate of the light of the object in the controlled space field. Comparative Studies of Dodtverde ° and the practical usefulness of this invention. As a result, the use of the pre-encoding encoder in the assembly of a matrix containing about 1.0 light-conducting harnesses is only about one hundred wiring harnesses for the coordination with the same accuracy. Claims of the invention The optoelectronic position sensor of an object, containing a fiber optical encoding device, is on b. the travel end of which is each of the light guide members. divided into several beams, the number of which depends on the number of units: a valid code, equal to the measure of the given leisure time, and photo receptionists, established by iiy4KOB, v about t and - “with this: sensors, optical receivers are made of rings, the input end of the fiber-optic encoding device is made in the form of a rotating disk with the light-guide harnesses laid on it in the form of a straight line, which are placed in the form of a concentric line on the output end of the fiber-optic encoder x rings.
