[Abstract]:With the rapid development of industrialization, mechanical vibration monitoring system is widely used in metallurgy, petrochemical, electric power, machinery manufacturing and other industries. There are a large number of machinery and equipment, such as motors, pumps, fans, compressors, gearboxes, which need to monitor the changes of the vibration amplitude, frequency and other physical quantities of these rotating machinery in order to understand the working state of the equipment. Timely alarm of equipment faults and diagnosis of equipment faults through collected vibration signals. According to the needs of users and the present situation of vibration testing technology, this paper designs a high-speed DSP multi-channel vibration signal analysis system based on ADI, considering the factors of cost and development difficulty, and studies the method of vibration signal processing. The main contents of the thesis are as follows: 1) the status quo of vibration signal analysis system technology at home and abroad is studied, and the hardware implementation scheme of front-end vibration signal acquisition device is designed, and the design of each function module of front-end vibration signal acquisition device is completed. The terminal analysis software of vibration signal analysis system is developed and designed, including vibration signal data preprocessing, vibration acceleration integral, spectrum analysis, graphic display, etc. Database operation and other program modules. The debugging results show that the system meets the design needs of users and achieves the desired design goal. 3) the vibration signal analysis system front-end acquisition device and terminal analysis software are combined and adjusted. The debugging results show that the system meets the design needs of users and achieves the desired design goal. The vibration signal analysis system designed in this paper has certain popularization and application value.
