Abstract

The invention discloses an on-line continuous environmental air quality automatic monitoring base station, an automatic monitoring network system composed of a plurality of non-point source grid base stations and a data processing center, and a method of tracing with the system. The base station consists of an automatic sampling module, a sensor module and a meteorological monitoring module that are connected to a data transmission module. The data processing center monitoring the network system is equipped with databases, terrain data and a meteorological diffusion model. Once sampling occurs to the base station disposed in a protection zone of the system due to the deterioration of air quality, the data processing center runs the meteorological diffusion model according to real time data, calculates the occurring source that can affect the protection zone in the monitoring zone, and starts the base station set nearby the occurring source to perform sampling, a fast gas phase electronic nose is utilized to perform gas sample fingerprint analysis on the collected sample and compare fingerprint technology similarity, and the source can be traced according to the similarity. The system and the method have the characteristics of high precision, fast analysis speed and real-time grabbing of air samples, and provide sample guarantee for tracing positioning.

Description

technical field [0001] The present invention relates to an online continuous ambient air quality automatic monitoring system, and further relates to a system for locating and tracing the source of peculiar smell in the air combined with a diffusion model to set up automatic sampling and fingerprint analysis and comparison, and a method for tracing the source using the system. Background technique [0002] For the convenience of description, the names used in this manual are as follows: [0003] Odor: a smell that gives people an uncomfortable and uncomfortable feeling; stench: a severe odor, which belongs to the peculiar smell; the usage of this name is not strictly distinguished. Odor / odor gas sources refer to some production units, landfills and other emission sources that release odor / odor gases. Protected areas refer to areas where air quality needs to be protected, such as residential areas and densely populated areas. Generally, they leave the corresponding monitori...
