GPRS-based wind power gear box remote monitoring and diagnosis method

Abstract

The invention discloses a GPRS-based wind power gear box remote monitoring and diagnosis method. The GPRS-based wind power gear box remote monitoring and diagnosis method obtains the on-line operating temperature, pressure and vibration signals according to the design operating conditions of a wind power gear box and converts the signals into digital signals, and feature signals reflecting the operation health state of equipment are calculated and obtained through a DSP processing module and sent to a GPRS module; the GPRS module transmits feature diagnostic information to a remote control center through the serial port communication technology, the virtual serial port technology and the mobile network entry technology and realizes remote monitoring and diagnosis of the wind power gear box. The GPRS-based wind power gear box remote monitoring and diagnosis method can realize low-cost and low-threshold remote on-line monitoring and diagnosis through the GPRS technology, largely reduces the on-site construction difficulty and network distribution cost of an on-line system and has important engineering value.

Description

technical field [0001] The invention belongs to the technical field of power equipment monitoring, and in particular relates to a GPRS-based remote monitoring and diagnosis method for a wind power gearbox. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world under the circumstances of energy shortage and increasingly severe environmental pollution. Under the national policy trend of vigorously promoting energy conservation and emission reduction, the development prospects of renewable energy, especially wind energy, are very broad. [0003] Due to the harsh operating environment of the wind turbine and the special installation location of the wind turbine, the maintenance cost of the wind turbine is very high, and once it is damaged, it will have a great impact on the power grid. Therefore, high requirements are put forward for the reliability of the wind turbine. The general requirem...

AI Technical Summary

Problems solved by technology

There is a problem with the above-mentioned monitoring and diagnosis system device, that is, the on-site network connection conditions are limited. Since wind power gearboxes often operate in harsh environments and remote areas, it is very difficult to install an Internet network interface on site and connect to the network. It also greatly improves the monitoring and operating costs of the system
