Electronic nose system and air source identifying and positioning method thereof in warehouse

Abstract

The invention discloses an electronic nose system and an air source identifying and positioning method thereof in a warehouse. The electronic nose system comprises an air inlet and filtering component; an FAIMS gas filter; a gas sensor array; and a data processor, wherein the data processor is connected with the gas sensor array, and used for extracting a sensor array information main component according to a sensor array signal, according to the extracted sensor array information main component, establishing a neural network, training the neural network by applying mass data in a database, and after determining a neural network model and parameters, performing mode discrimination on a sample gas to be detected in an warehouse environment. According to the electronic nose system, a gas screening filtering device is additionally installed, interference components in a mixed gas from the environment are reduced so that the interference is filtered by the system, and the precision of thegas detection in the warehouse environment can be improved.

Description

technical field [0001] The invention relates to the field of electronic analysis instruments, in particular to an electronic nose system and its gas source identification and positioning method in storage. Background technique [0002] An electronic nose system is an electronic system that uses the response of an array of gas sensors to identify odors. It is an instrument composed of selective electrochemical sensor arrays and appropriate identification methods, which can identify odors and obtain results consistent with human sensory evaluation. [0003] With the rapid development of the logistics industry, warehousing has developed from a single storage function to a storage center that undertakes multiple functions, such as order processing, sorting, packaging, secondary processing, and manufacturing. The quantity and variety of goods stored in the storage center are increasing, and the number of staff involved in the operation is also increasing. There are many potenti...

AI Technical Summary

Problems solved by technology

There are many potential pollution sources in the warehouse, which directly affect the quality and life of the goods, and affect the health of warehouse workers.

[0004] When using the electronic nose system to monitor the storage environment, there are problems such as "broad-spectrum" and "cross-sensitivity" of sensor measurement, and the measurement accuracy of gas mixture in the storage environment is not high.
