Abstract

The invention relates to an optical fiber sensor and an object position and attitude monitoring method applied to the optical fiber sensor. By using multiple probes, multiple optical power meters and a processor, the position of the object can be determined according to the detected light intensity And attitude offset, while improving the accuracy of object position monitoring, it can determine the attitude deviation between the sensor and the object, so as to accurately monitor the attitude change of the object. Moreover, the whole technical solution not only has the position measurement function of the existing optical fiber position sensor in the market, but also adds the attitude measurement function, which can further make up for the defect that the position and attitude measurement cannot be performed simultaneously in the current industrial sensor detection work. At the same time, the diversity of sensor types is increased, which provides technical support for further improving the intelligent production of industrial product development.

Description

technical field [0001] The invention relates to the field of optical smart sensors, in particular to an optical fiber sensor and a method for monitoring object position and attitude. Background technique [0002] Since the 1960s, fiber optic technology has developed rapidly, and sensors based on fiber optic principles have been continuously developed and applied in the field of industrial automation. In the production of industrial assembly line, the photoelectric switch is one of the essential monitoring sensors. The photoelectric switches arranged on both sides of the assembly line can keenly sense the movement status of the industrial products ahead, and send out instruction signals to control the assembly line to make corresponding adjustments to the industrial products. [0003] But at this time, the photoelectric switch can only sense the presence or absence of the object in front, but cannot obtain the exact position of the object, and its application range is narrow...
