Study on a New Type of Automobile Exhaust Detecting System

Abstract:

While the development of automobile has provided convenience to people's daily life and economic activities, vehicle exhaust has also brought serious environmental pollution. The harmful gas produced by cars contains hydrocarbons and hydronitrogens. Among them, acetylene gas which belongs to atmospheric trace gases, cannot be affected by environmental factors. With the theory of tunable diode laser absorption spectroscopy (TDLAS) technique, wavelength modulation and harmonic detecting technique, this system uses the intelligent data acquisition and processing system based on MSP430 to detect acetylene gas in real-time and display the vehicle exhaust. The system has a good stability, high measuring accuracy and long service life. It is cheap and easy to maintain. It realized low power design.
