Abstract:

In order to understand the wind turbine blade vibration,and then judge its failure type,the paper designs a wireless signal acquisition system with the low power consumption MSP430 microcontroller as the core control unit.Its hardware is composed of the signal processing module,the wireless communication module,and the MSP430 microcontroller control system.Its software adopts modular design.The system is usually dormant and the CPU stops running until interrupted by software requests.The experiment proves that the module design is stable and reliable,with high-speed data transmission,low power consumption and high versatile,and a bit error ratio of only 1%.

Key words: MSP430 microcontroller;low-power consumption;wireless collection
