Optoelectronic SEMS for Preventing Object Destruction
Control and monitoring of supporting structures are important part of ensuring security in the work area of robots. Late detection of deformations leads to the destruction of the object and possible material damage. The purpose of the work is the development SEMS for remote control of supporting structures of infrastructure objects to prevent destruction in the area of robot operation. The result is an optoelectronic device capable to control angular and linear movements of the object being monitored and warning of critical displacements. The proposed solution is integrated into the overall monitoring system. The possibility of creating a single-channel four-coordinate device capable of real-time monitoring of the position of an object and warning of critical deformations and displacements has been proved. The sensitivity and accuracy of the device is comparable with commercially available two-coordinate devices. The proposed option is small in size, more compact and can be installed at a distance of up to 5 m. Mathematical models have been developed to evaluate the effect of various measurement error on the result. Specially designed software allows to compensate for errors within the device and expands the metrological range of measurements with solving the problem of inoperability in the case of overlapping image in the field of analysis through the use of Hough Transformation. A passive reflector that does not require power supply is installed at the monitoring point. The practical significance lies in the possibility of using SEMS with the optical-electronic part for solving problems of monitoring and ensuring the safety of both robots and humans.
