In order to detect weak chemiluminescence signal rapidly and high accurately, a chemiluminescence detection system is designed based on the core chip FPGA. The system uses a static injection mechanism as chemiluminescence reaction conduit. High-performance photodiode converts chemiluminescence signals into electrical signals replacing the traditional photomultiplier tube. It can meet the test requirements while reducing the cost of the detection system. The signal processing and storage system FPGA-based consists of A/D converter module, serial communication module, the keyboard scan control modules and memory modules. Nitrite ions in water samples are detected and the results show that in a certain concentration range the calibration curve of NO2- concentration and luminescence intensity is linear, the linear regression equation is Y = 0.4148X + 2.6508, and the correlation coefficient is R2 = 0.9832. The relative standard deviation values are 2.7%(n=11).
