Application Of The Wavelet Analysis In The Fault Diagnosis Of Rotating Machines

Since the energy crisis, with the improvement of all energy conservation and environmental protection consciousness, make more bright future of the global LED lighting market. With the progress of technology, LED lighting has become a new growth point of electronic information industry. Under the double stimulations of the market and the policy, the global LED lighting industry is a trend of rapid growth. To promote the rapid development of LED industry, as early as during the period of "15" in China had increase support for the LED lighting industry, especially in the recent ten years have introduced a number of important supporting policies, so the LED lighting enterprises have mushroomed. However, while LED lighting technology rapid development, but LED lighting products especially LED street lamps in practical engineering applications have a lot of questions.The main reason is now that the LED lighting enterprise not enough emphasis on the reliability of the product management, lead to enterprise in the design, production and use of LED lighting products have a lot of questions, cause a loss to LED lighting enterprise.This article through to improved the reliability management of the Q company, to improve the reliability of products. Through the FMECA method to analysis of the reliability problem of the Q company, appropriate improvement, and the appropriate reliability tools into the enterprise management system, throughout the product design, production, use and maintenance of the entire life cycle, make after-sales returns, repair, complaints reductions and strive to product quality reliability level one step, and through the quality reliability of reengineering process make the Q company formed mature quality reliability. Reliability management from the perspective of system management, through the formulation and implementation of a series of scientific plan, to organize, control and supervise the activities of reliability, to ensure that the use of minimal resources, to achieve the requirements of product reliability. The LED street lamp of the Q company product are variety, but now need to meet the different needs of users at the same time, we from the person, the machine, the material, the method, the ring, the measuring, such six aspects, formulated and implemented such as scientific planning, use the correctly tools of the reliability management, to ensure that the Q company organization, control and supervision of the reliability activities smoothly, guarantees the enterprise in the case of using minimal resources, to achieve the requirements of product reliability.For the other LED lighting company, in the product under the condition of no breakthrough progress has been made in technology, in the case of the relevant reliability standards unpublished, can use the appropriate means of reliability management, in the design, the production, the management, the maintenance, the reliability of the process in order to enhance the quality of the product reliability.
