Aiming at present problems that inconvenient installation

maintenance and limited monitoring point existing in cable monitoring system

a kind of wireless sensor networks（ WSNs） monitoring system based on Zig Bee technology is designed. After Zig Bee protocol is converted to TCP / IP protocol by the gateway

datas collected by Zig Bee subnet

is transmitted to central server via optical network

once logining in the page

the wireless monitoring system can be displayed and controlled

and intelligent monitoring of wind turbine is realized. Test show that the measurement precision can meet design requirements

high efficient and high reliable monitoring is realized

and remote data service is provided by Internet

datas can also be analyzed and mined offline.
