Quantitative detection of fluorescence immunoassay is widely used in clinical detection. For this reason, through a reasonable design of optoelectronic circuits real-time detection system, designing a set of fully functional fluorescence immunochromatographic quantitative detection system is necessary, which integrates a large number of peripheral modules, including fluorescence signal collecting, motion control, fluorescence signal processing data, quantitative curve fitting and testing results. After the improved threshold wavelet denoising through experiments, the system performance is very good, quantitative results are accurate. So, the system of fluorescence analysis has a vital significance.

In order to improve electrical power forecasting accuracy of the Energy Internet this paper proposes a gray RBF model improved by genetic algorithm. This method forecasts power of the micro-grid using the characteristics that gray model can weaken data randomness and RBF neural network is highly nonlinear.
