Embodiment Construction

[0031] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0032] Such as figure 1 As shown, the embodiment of the present invention proposes a kind of detection method of car smell, comprises the following steps:

[0033] S01: Build an odor data model

[0034] Specifically, the embodiment of the present invention uses the following two methods to establish an odor data model. The first method is: select N grades of automobile samples, place each grade of automobile samples in a preset space, and place them at a temperature of 23 Place for 2 hours under any one of conditions within the range of -80°C and a relative humidity of 20%-80%. In the embodiment of the present invention, the storage conditions are as follows: the temperature is 65±2°C. The N grades can be evaluated by the odor evaluation method of German VDA270, or by the chromatographic peaks detected by the GC-MS equipment. Under the preset measur...

Abstract

The invention discloses an automobile odor detection method which comprises the following steps: establishing an odor data model; placing a to-be-tested automobile sample in a preset space for a predetermined time; collecting gas data in the preset space; using the odor data model to analyze and calculate the collected gas data to obtain the level of odor of the to-be-tested automobile sample. The automobile odor detection method aims to solve the technical problem of low evaluation efficiency of the automobile odor evaluation method in the prior art.

Description

technical field [0001] The invention relates to the technical field of odor detection, in particular to an automobile odor detection method and detection system. Background technique [0002] With the enhancement of people's awareness of environmental protection, consumers have higher and higher requirements for the air quality in the car. When people subjectively feel the air pollution in the car, they mainly feel the smell in the car. At present, the evaluation method of automobile odor is generally made by inspectors to make olfactory judgments on the parts / materials of automobiles under preset conditions. The repeatability of the car odor evaluation results is not ideal due to the influence of the testers on personal emotions, physical conditions and odor preferences. In addition, when it is necessary to check the odor sources of the whole vehicle one by one, this method of automobile odor evaluation requires a huge amount of work and the evaluation efficiency is not h...
