Description

A kind of Wind turbines fault information acquisition system based on F28335DSP

Technical field

The utility model relates to the Wind turbines fault information acquisition system based on F28335DSP, belongs to wind power generating set fault diagnosis technology field.

Background technology

Under the background emphasizing protection of the environment, sustainable development now, the wind-power electricity generation of consumption of fossil fuels, non-environmental-pollution is not considered to the most clean energy utilization type.In in the past 10 years, because annual average rate of increase is close to 28%, wind-power electricity generation has become the fastest-rising class renewable sources of energy in the world.Recent years, because the development of China's wind-power electricity generation installation amount is rapid, the fault diagnosis technology of corresponding wind power generating set there has also been certain progress, but compared with speed of development faster wind power equipment, the fault diagnosis technology of wind power equipment need further raising.In addition, due to the singularity of wind-powered electricity generation industry, equipment operation and maintenance somewhat expensive.According to statistics, wind power equipment operation and maintenance cost exceedes 10% ~ 15% of total revenue, and carries out more changing jobs of a gear case and will spend unit up to a million.Therefore, at present in the urgent need to studying a kind of on-line fault monitoring and diagnostic method, Timeliness coverage fault initial stage sign, prevents the generation of catastrophic failure or serious accident.

Because wind power generating set many places are in remote districts, the fault information acquisition of Wind turbines is also more difficult, the more difficult discovery of failure ratio of wind power generating set, is in most cases after Wind turbines breaks down, directly change the parts broken down.Therefore, research and develop a set of in time and effective Wind turbines fault information acquisition system have great importance.

Therefore, the fault diagnosis gathering Wind turbines seems particularly important, is the key ensureing the operation of unit long-term stability and safe power generation.The economic benefit that a set of effective Wind turbines fault information acquisition system is conducive to reducing failure rate, reduces servicing time, increases annual electricity generating capacity and raising wind energy turbine set; Be beneficial to discovery initial failure, the necessary time can not only be provided for unit maintenance personnel placement standby device and goods and materials, and guidance and suggestion can be provided for designer.

Summary of the invention

State problem, the technical problems to be solved in the utility model is to provide the Wind turbines fault information acquisition system of a kind of base F2833DSP.

The utility model is a kind of Wind turbines fault information acquisition system based on F28335DSP,

This system mainly comprises: piezoelectric acceleration sensor, power module, TMS320F28335DSP chip, data acquisition and processing (DAP) module, data memory module, communication module, house dog and power-off restoration module.For the plurality of voltages current signal that collects after current transformer conversion, enter outside AD sampling A/D chip MAX11046 after being switched by analog switch chip CD4066, then the signal after the conversion of AD sampling A/D chip is sent into DSP by data bus DB0 ~ DB15 and carry out algorithm process.TMS320F28335DSP is inner integrated bus for expanding external chip EEPROM and clock chip RX8025, for realizing storage and the terminal time adjustment function of outside important parameter.Serial communication interface SCI realizes communication through level transferring chip and host computer by RS232.Because wind power generating set working environment is comparatively complicated, DSP is vulnerable to external interference when Information Monitoring, causes program fleet or deadlock, can realize DSP automatically reset by watchdog chip, makes system program recover normal and runs.

As preferably, then the information of collection pass to DSP by AD synchronized sampling chip through analog switch chip.

As preferably, described Wind turbines fault information acquisition system realizes communication through RS232 interface and host computer.

For preferably, described Wind turbines fault information acquisition system by external interference program generation sideslip or when crashing at DSP, can realize DSP by watchdog chip and automatically reset.
