Abstract

The invention provides a power transmission line wave monitoring remote intelligent sensor. As the wave of a power transmission line generally occurs in remote areas with severe environments, the convenience in transportation and installation of a monitoring sensor is required. In the invention, by integrating master / standby sensor chips, the master / standby sensor chips are connected with master / standby clock chips, master / standby watchdog chips and master / standby DSP (digital signal processor) chips respectively; the master / standby sensor chips are connected with a ZigBee chip and an SD card; and all chips are integrated on a circuit board, thereby realizing a small volume and facilitating transportation and installation. In the invention, data are subjected to FFT (fast Fourier transform) calculation and sent out by the ZigBee chip, thus the data loss rate is low, the data volume is small, the power consumption is ultra-low, and the data transmission does not depend on an external network; and the data are stored by the SD card, thus the historical data are kept.

Description

technical field [0001] The invention relates to the technical field of transmission line monitoring, in particular to a remote intelligent sensor for monitoring galloping of transmission lines with ultra-low power consumption and short-distance wireless data transmission. Background technique [0002] During the operation of transmission lines, many disasters and accidents will occur due to the effect of natural conditions, and galloping is one of the more serious hazards. Galloping is a low-frequency (0.1-3Hz) and large-amplitude (20-300d) self-excited vibration phenomenon caused by uneven stress on the conductor section under wind excitation. The hazards of wire galloping are many. The light ones will cause flashover and tripping of adjacent lines, and the severe ones will cause damage to hardware and insulators, and even tower collapse. [0003] At present, researchers at home and abroad have studied the galloping of overhead line transmission conductors, and have achiev...
