[Abstract]:At present, all kinds of wireless vibration sensor products have been widely used in various detection fields. In order to overcome the shortcomings of the power supply chemical batteries, the piezoelectric power supply is regarded as the hot spot of self power supply for the current micro power electronic equipment. The basic characteristics of the piezoelectric ceramics, the structure design of the electric device, the design of the energy collection circuit and the combination of the energy recovery device and the MSP430F149 chip are four key points. The output power of the whole structure is obtained by using the stable 50Hz and 100Hz vibration source provided by the laboratory. The power of the whole structure is obtained, and its supply to the MSP430F149 chip is demonstrated. The whole experimental platform is built, and the final experimental platform is built. The final result of the experiment proves that the piezoelectric ceramic cantilever beam can be used to collect the vibration energy. The device can be used as the power supply for the micro power electronic components. The first chapter introduces the development and significance of the vibration energy recovery. The application of the product power supply field. Finally, the innovation point and main research content of the paper are put forward. The second chapter expounds the basic principle and basic characteristics of the piezoelectric ceramic work. The theoretical analysis of the vibration energy process of the piezoelectric ceramic cantilever beam recovery is made, and the four important components and the present research status are introduced. The third chapter describes the piezoelectric ceramics. On the basis of the basic principle of porcelain work, the ANSYS simulation analysis of the piezoelectric ceramic cantilever beam is carried out. According to the simulation results, a structural solution which can adapt to the frequency of vibration source is proposed and designed. In the fourth chapter, the piezoelectric ceramic cantilever beam is made on the basis of the existing vibration source, and the whole experimental platform is built. The energy recovery circuit of the MSP430F149 chip is designed and built. The circuit is optimized according to the experimental data. Finally, the production of the whole piezoelectric cantilever energy recovery device is completed. The fifth chapter uses the whole experimental device to combine it with the minimum system circuit of the MSP430F149 low power consumption chip and write a low power consumption process. Order, verify the use of piezoelectric ceramic cantilever beam to collect vibration energy, and provide energy to low power electronic components. The sixth chapter summarizes the work of the whole paper, describes and analyzes the situation in this paper, and extends and prospects the research topics.
