In the proposed Circular Electron Positron Collider (CEPC), the silicon pixel vertex detector demands high spatial resolution, low power consumption, and minimal material budget, posing significant challenges in chip design and detector fabrication. TaichuPix series chips, based on complementary metal-oxide semiconductor technology, were specifically designed for the CEPC vertex detector. The first full-size engineering chips, TaichuPix-3, were utilized in the development of the vertex detector prototype. To test and investigate the performance of the chips and the prototype of the vertex detector in beam experiments, a dedicated data acquisition system was developed. Based on the javafx framework and programmed in Java, the system efficiently manages the electronics configuration, data collection, online data verification, and real-time monitoring of the detector prototype, while also providing a user-friendly graphical interface for run control. Laboratory tests and beam tests have validated the data acquisition system in terms of functionality and operational stability, confirming that it fully meets the experimental requirements of the silicon pixel vertex detector prototype.
