Fiber-Optic Sensor for Monitoring Synchronicity of Actuators
In most projects aimed at modernization of existing production lines and units a new group of mechatronic objects - interconnected multi-motor electric drives - is used. For the efficient and safe operation of this type of drives it is necessary to solve a number of problems, one of which is the development of methods and tools to synchronize the rotation of activators dynamically. The purpose of the research is to create a non-contact sensor for measuring the rotation of the activator. The basis of the developed sensor is a fiber optic converter with external modulation, with which you can implement a non-contact method of measuring displacement of reflective label installed on the shaft of remote devices. To compensate the non-informative factors affecting the accuracy of the position measurement, the original block diagram and processing algorithm were developed which provides stable and accurate registration of appearing the reflective labels under the fiber end when using the sensor in a production environment. The results of the research have made a theoretical basis for the design of the two measuring devices: a high-speed tachometer and a sensor for control of synchronicity rotation in the dynamic mode.
