| Abstract: | A real-time detecting system online for monitoring H_2O in the gas of SF_6 concentration with infrared laser spectral detection principle is introduced. Applying infrared detection technology based on the molecular absorption of radiation theory,the photoelectric sensor for H_2O density detection is designed. The ARM hardware platform centralized on S3C44B0 is developed. It consists of A/D conversion module, LCD display module and GPRS module by RS-232 bus. Compared with the traditional instruments, it has high sensitivity,good at repetition and powerful in real-time. The detecting precision reaches 0.001 % , which is an ideal equipment for detecting H_2O concentration in the use of the gas of SF_6. |
