This paper designs and implements a data acquisition system for AETA (Acoustic and Electromagnetic Testing All in one system). The data acquisition system is mainly divided into three parts: probe data acquisition software, data processing terminal software and server application. The data processing terminal software is the core, which is responsible for receiving the data collected from the probe and transmitting it stably and reliably to the server. The proposed system also has the function of automatic upgrade and online execution of commands, which can realize remote operation and maintenance of the device. Tests show that the AETA data acquisition system can run stably with network speed as low as 10 KB, and can respond to remote commands in a minute. It has good stability and real-time interactivity, and is suitable for cross-region and high-density layout of seismic monitoring system equipment.
