Abstract: With the development of the times and technology, all devices are developing toward network and intelligence. In the circumstances, how to develop a networked and intelligent nondestructive testing equipment has a special meaning. In the paper, we apply the WiFi wireless technology into the nondestructive testing equipment based on Barkhausen noise, and develop the networked and intelligent nondestructive testing equipment. With the equipment, we can realize the remote control, remote transmission, remote upgrade, remote alarm and so on.
