A telemetring technique on deformation of large tower
摘要
Abstract
This paper describes a telemetring technique on deformation of large Electrical Power Equipment. We install n radio beacons apart △Hi each other at large structure. The carriers of n beacons are same but modulated by different orthogonal PN codes. So the telemetring equipment can divide the carriers of n beacons. The phase detectors measure the phase difference between the ith carrier and (i-1)th carrier △θi (i=2, 3…n). The corresponding deformations are △Li=△θi/360×λ(i=2, 3…n). The deformation curve can be deduced from △Li and △Hi(i=2, 3…n). The method to eliminate the interference between the modulated carriers is presented. The simulation test is conducted and the result of the simulation proves the effectiveness of the proposed technique.关键词
