The invention relates to a technical method for solving data overflowing in a ground penetrating radar data collection system. The technical method mainly solves the problem of data overflowing and losing due to high real-time data sampling efficiency and low transmission and storage speed. The method includes the steps that 1, in the ADC initialization process of a digital converter, double collection modes are synchronously configured, and optimal collection parameters are set; 2, a multithreading data collection workflow is designed, tasks of reading and transmitting ground penetrating radar data and header file data are finished, and the problem of data overflowing due to low read speed is solved; 3, a data storage workflow is designed, and integral storage of the collected data is ensured by setting up a data storage queue structure. As the computer technology and the electronic information technology are coupled together, the problem of data overflowing in the ground penetrating radar data collection system is solved, and the data can be collected and stored in real time successfully.
