【Abstract】 Aim\ To design an instrument of combustible gas detector of wavelet transform type. Methods\ The detecting instrument is designed according to the wavelet transform technology and national standard of combustible gases of China (GB15322 94) and the national standard of the essence safety type circuits of China (GB3836.4 83)Results and conclusions\ Four conclusions have been obtained for the detecting instrument:firstly, because the wavelet transform technology is adopted,the detecting instrument has the capacity of good antijamming,and the error alarms are prevented;secondly, the detecting instrument is essence safety type; thirdly,the functions of temperature and humidity are good; fourthly ,the long term stability is good.更多还原
