Space radiation detection is an important requirement for space activities,and data collection is a im-portant part in space radiation detection systems,mainly including waveform digitization and online data process-ing.The system uses FPGA chip as the main control chip.An A/D converter,data online processing module,and LCD display screen driver are designed in the hardware part of the system;and in the software part of the system,the UI interface of the display screen is designed by uC/GUI,then it is ported to the Nios II processor in the FPGA chip,and corresponding touch buttons and parameter display functions are written in Eclipse.Finally,the system is tested with waveform generator and γ radiation source.The test results show that the system suc-cessfully realizes the function of data online processing,and can measure the intensity and frequency of radiation waveform under different conditions;the displayed waveform is consistent with the ideal waveform.
