Wind turbine generator gear case remote monitoring device

Abstract

The invention discloses a wind turbine generator gear case remote monitoring device. The wind turbine generator gear case remote monitoring device comprises wireless multiclass sensor terminals, an embedded router and a GPRS data transceiver terminal, wherein the wireless multiclass sensor terminal comprise integrated sound emission, vibration and temperature multiclass sensor modules, amplification modules, data acquisition and processing modules and wireless data transceiver modules. During monitoring, the multiple wireless multiclass sensor terminals are distributed on monitoring points of a wind turbine generator gear case, the wireless multiclass sensor terminals detect temperature, vibration and sound emission data of the monitoring points in real time, and the data is sent to the GPRS data transceiver terminal through the embedded router and is remotely transmitted to a data analysis processing computer of a main station. The wind turbine generator gear case remote monitoring device employs digitalization, modularization and radio transmission technologies, solves problems of over-long connection wire, complex mounting and difficult maintenance of a traditional wired monitoring device, and further solves a problem of single-class measurement existing in the traditional monitoring device employing a vibration sensor.

Description

technical field [0001] The invention belongs to the technical field of wind turbine gearbox monitoring, and relates to a remote monitoring device for a wind turbine gearbox. Background technique [0002] The gearbox in the wind turbine is a very important and one of the most expensive components. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator to obtain the corresponding speed. Due to the harsh working environment of the gearbox itself, it is vulnerable to damage and failure; and the components such as gears, shafts, bearings, etc. The high rate is an important cause of machine failure. According to statistics, gearbox faults account for more than half of wind turbines. Online condition monitoring and fault diagnosis technology can help discover initial faults of wind turbine gearboxes, contain major accidents, and prevent joint failures; condition monitoring is also conducive to discovering some extreme ...
