Abstract： Aiming at the problems of complex installation，high power supply and maintenance costs of existing transmission line wind deflection/galoping monitoring terminals，this paper proposes a wireless intellgent monitoring scheme based on spacer dampers：MEMS（micro-electro-mechanical-system）thre-axis inertial sensors are embedded in the spacer dampers to obtain the three-directional vibration and torsional responses of the conductors;combined with the compressed sensing framework and the orthogonal matching pursuit （orthogonal matching pursuit）reconstruction algorithm，the sparsity of data is utilized and a Gaussian random sensing matrix is adopted to realize the reconstruction of the ful-line galloping curves.The simulation and experimental results show that： under the given span condition，the sparsity can be adaptively set with the sampling length; when the observation ratio is 10% to 20% ，high reconstruction accuracy can be achieved，which meets the online monitoring needs of long-span lines.This wireless intelligent spacer damper monitoring scheme provides an engineering feasible path for the real-time monitoringand reconstruction of transmisson line wind deflection/ galloping.

Keywords： MEMS sensor; orthogonal matching pursuit （OMP） algorithm; conductor galloping
