APPLICATION OF NRF905 WIRELESS TRANSCEIVER MODULE ON WIND-POWER BLADES ACOUSTIC EMISSION TESTING

Abstract

Abstract: For kinking problem of testing of running blades with cable equipment, the paper puts forward using wireless technology for running blades' condition monitoring. And design a wireless detection system based on acoustic emission signal using the idea of modular design. Beijing shenghua SR150M was chosen as the acoustic emission sensor to test acoustic emission signal, 12C5A60S2 of STC series single-chip was selected as the microcomputer control unit to store data and control the transceiver, and the chip of NRF905 was used as the wireless data transceiver module. PC design using VB, and the system implements the data receiving process. Testing results show that the system is reliable for data detection and transmission processing, and it can realize condition monitoring of the blades. The system software is portable, and it provides a method to monitor of rotating objects.

Key words: blade, acoustic emission technology, wireless monitoring, NRF905
