SYSTEM FOR MONITORING FOR CONDITION OF WIND POWER GENERATOR USING WIRELESS SENSOR NODE

摘要

The present invention discloses a wind power generator state monitoring system using a wireless sensor node capable of effectively monitoring the state of a wind power generator. At the system according to the present invention, the wind power generator forms one or more clusters. The each cluster is made of; multiple local area network modules which include a vibration sensor, a temperature sensor, a humidity sensor, a voltage sensor, and a current sensor, and measures the state of the wind power generator from a wind direction sensor and a wind speed sensor and wirelessly transmits the measured state information; a router which corrects the state information of the wind power generator provided from the local area network modules and loads it in Ethernet network; a management computer for monitoring the state information of the wind power generator by being connected to the Ethernet network. The topology for communications between the local area network module and the router is one among a STAR type, a RING type, a CLUSTER TREE type, and a MESH type. The router is connected to the Ethernet network through a cell phone or a public switched telephone network (PSTN) according to an installation environment of the wind power generator. Therefore, the present invention has an effect which demonstrates the flexibility of system facilities according to the installation and management conditions of the wind power generator by monitoring the state of the wind power generator using the local area network module and the router in real time.
