英文摘要：

In order to strengthen the practicality and flexibility of Electromagnetic Ultrasonic, a novel remote portable electro- magnetic ultrasonic data acquisition and analysis system was designed. The system controls the exciting of electromagnetic ultra- sonic and receiving circuit via serial port.The electromagnetic ultrasonic signals which are obtained using data acquisition card were analyzed and processed. The exciting and receiving circuit parameters of electromagnetic ultrasonic and signal analysis pa- rameters can be uploaded via mobile terminal （smartphone or tablet） which is able to access to the network server remotely through mobile base stations or LAN.Meanwhile, the data of electromagnetic ultrasonic signals can be received and displayed in real time on the mobile terminal.Thereby, the remote control of electromagnetic ultrasonic circuit and the portable acquisition and analysis of data were achieved.Experimental results showed that this method can achieve the online collection and mobile analysis of electromagnetic ultrasonic signals.And the system could be adjusted and controlled remotely.The proposed method is stable and reliable and has great scalability which will enrich the electromagnetic ultrasonic applications significantly.
