Abstract

Embodiments of the present invention provide a vehicle VOC concentration detection system and method. The car VOC concentration detection system includes: a plurality of ultraviolet lamps with different ionization energy specifications set in the car cockpit to generate high-energy ultraviolet rays to activate the VOC gas in the car cockpit to generate ionization energy signals; set in the car cockpit, A PID sensor array for collecting corresponding ionization energy signals and performing signal processing on the ionization energy signals to obtain corresponding electrical signals; electrically connected to the PID sensor array for signal amplification of electrical signals to obtain amplified A signal amplifying circuit for the electrical signal; and a processor electrically connected to the signal amplifying circuit for signal processing the amplified electrical signal to obtain corresponding VOC concentration data. Thereby, real-time detection of the VOC level in the vehicle cockpit can be realized efficiently, and no harsh experimental conditions are required, the operation is simple, the cost is low, and the detection effect is good.

Description

technical field [0001] The invention relates to the field of automobile air pollution detection, in particular to an automobile VOC concentration detection system and method. Background technique [0002] At present, domestically, the headspace test method and the sampling bag test method are mainly used for vehicle VOC testing in China. Both of the above two methods require samples to be collected and placed in a laboratory environment for testing and analysis under specified experimental conditions. In addition, there are chemical analysis methods in the industry, but there are many interferences, harsh conditions, and lack of convenience; while the instrument analysis method has huge experimental equipment, complicated operations, long time, and expensive prices. The above methods cannot be used to determine the VOC level in the car cockpit. Perform real-time detection. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prio...
