Design of Embedded Data Acquisition System for 60Co Boat Radiation Imaging

The embedded data acquisition system for ⁶⁰Co boat radiation imaging was designed, and the components of data acquisition system based on the modular drive and network transmission were introduced. Interface design of the system is simplified by multiplexing signal. As a control center, the embedded system receives control commands through Ethernet from PC, forms collect and control cycle timing, reads data from preamplifiers, stores and transmits the buffer data to PC. This data acquisition system has following performances, such as simple interface, easy to expand, reliable.
