Research on the automatic dynamic balancing emendation integrated system with remote manipulating ability

摘要

In order to satisfy the needs of advanced dynamic balancing emendation technique, an automatic dynamic balancing emendation integrated system with remote manipulating ability, which took an embedded system as central controlling and measuring unit, was introduced. In the system, automatic dynamic balancing measurement, numerical control machining and workpiece-transfer manipulator were integrated, and two key techniques, including automatic dynamic balancing measurement and remote real-time data transmission, were studied emphatically. For the dynamic balancing measurement, an improved method of adaptive filtering based on harmonic wavelet was presented, an adaptive filter was designed by means of the phase-locking and narrowband analysis ability of harmonic wavelet, and the problem of abstracting unbalance quantity and its phase precisely in the environment of strong background noises with variable frequency structure was successfully solved. For the remote real-time data transmission, based on wavelet transformation, the remote environmental information and field operating parameters were collected, compressed and coded, an approach of collection and compression on video image data was advanced, and the time delay in network communication was forecasted and eliminated. On the basis of above works, an automatic dynamic balancing emendation integrated system with remote manipulating ability was integrated and applied in practice. Applied results indicate that this system runs with the performance of high efficiency, precision and reliability, can meet the needs of dynamic balancing emendation on a large scale, moreover, the system has got remote manipulating and maintaining ability.
