Abstract：High-speed EMU trains have many highly integrated electronic product systems. In order to ensure the safety of passengers and vehicles during train operation，it is necessary to monitor the fire prevention of detection points such as cab，electrical cabinet，air conditioning cabinet，passenger compartment，PIS cabinet，toilet and kitchen in real time.This paper introduces the design principle，calibration method and application case analysis of high-speed railway basedon dual-wavelength point pyrotechnic detector for highspeed EMU trains，and puts forward the design principle of new pyrotechnic detectors based on dualwavelength multi-parameters to realize the accurate detection of smoke，improve the smoke sensing precision， reduce the false alarm rate of pyrotechnic alarms，and meet the design requirements of electronic products for high-speed EMUs. The dual-wavelength pyrotechnic detector collcts dual-wavelength scatered light signals. The volume concentration and surface area concentration of smoke or aerosol are detected by two incident lights with different wavelengths，the soft algorithm calculates the volume concentration，surfacearea concentration and average particle size of the real-time smoke aerosol，and determines the ocurrence of fire alarm by combining the calibration coefficient of the pyrotechnic detector.
