Abstract
In order to satisfy the requirement of AE testing and monitoring for pipeline, large pressure vessel, large crane and amusement device, a new 16-channel high-speed Wi-Fi wireless acoustic emission system based on GPS and Wi-Fi techniques was developed. The test results indicate that this system possesses very high function and can satisfy common AE applications. The theoretical maximum distance between wireless controller and wireless AE acquisition units is up to 10 km. Three kilometers testing has been carried out at present. The transmitting rate is 7,000 hits/s or 3.6 Mbps between wireless controller and wireless AE acquisition units. The clock synchronization accuracy based on GPS can be up to 3 μs. It realizes time difference AE source location in real time. The system maximum error for steel plate is 77 mm. This accuracy can meet the requirements of most AE testing applications.
