An in-use gear-box wear-condition on-line visual monitoring system comprises a monitoring power supply, a constant temperature module, a sensor module, a data acquisition ARM module, data transmission and data remote analysis processing. The monitoring power supply is connected to the constant temperature module. The constant temperature module is connected to the sensor module and the data acquisition ARM module. The data acquisition ARM module is connected to the monitoring power supply, the sensor module and the data transmission respectively. The data transmission is connected to the data remote analysis processing. Real-time monitoring to a gear box wear state is realized and lubrication friction correlation data during an operation process is acquired. During a whole monitoring process, closed cycle is used when an oil liquid system is monitored, a return system of an over oil sample is monitored and an oil product is not damaged. An embedded ARM chip group is used as a data acquisition control module core so as to complete acquisition, control, transmission and other functions. Abnormal wear data is collected and analyzed as a picture form and a determination basis is provided for friction fault analysis.
Description
technical field [0001] The invention belongs to the technical field of state monitoring of large-scale active equipment, and relates to a large-scale gear box operating state monitoring system, in particular to a visual monitoring system and a monitoring method for the wear state of an in-use gear box. Background technique [0002] With the global energy crisis and environmental pollution becoming more and more serious, wind energy as a green energy has attracted great attention from all over the world. my country's medium and long-term planning clearly supports "focus on research and development of large-scale wind power generation equipment", and wind power equipment has gained rapid development. develop. According to the current growth trend, the World Wind Energy Association predicts that by the end of 2020, the global installed capacity will be at least 1.9×106MW. China continues to play a leading role in the world's wind energy development. At the same time, global of...
