Online solid waste identification system and identification method based on hyperspectral detection

Abstract

The invention relates to the technical field of solid waste classification, in particular to an online solid waste identification system and identification method based on hyperspectral detection. Theidentification system comprises a material conveying device, a type identification device, and a sorting device. The material conveying device transmits materials to the type identification device tocarry out data collection and then the data are transmitted to the sorting device for material sorting. The material conveying device includes a first conveyor belt and a second conveyor belt; and the materials are conveyed by the first conveyor belt and then fall on the second conveyor belt, wherein the first conveyor belt and the second conveyor belt have the opposite running directions. According to the provided system, the materials can be dispersed effectively; a problem of difficult type identification caused by material stacking is solved; and a problem of low efficiency caused by artificial dispersion is solved. With the identification method, two-dimensional images and spectral curves of solid wastes can be collected in an online manner; the solid wastes can be classified accurately and effectively; and the online solid waste identification system and identification method have important practical application values.

Description

technical field [0001] The invention relates to the technical field of solid waste classification, in particular to an online solid waste identification system and identification method based on hyperspectral detection. Background technique [0002] Our country is rich in land and resources, but due to the large population, the per capita land occupation and resources are relatively small. In order to use the land reasonably, it is necessary to continuously demolish old buildings so that the original land can be renewed for new buildings. A large amount of solid waste will be generated during the demolition process. If it is not handled properly, the solid waste will not only occupy a large amount of land and seriously affect the city appearance, but also cause many safety hazards if piled up randomly. At the same time, there are many reusable resources in the solid waste. Including many non-renewable resources, such as reinforced concrete and so on. [0003] At present, ma...

AI Technical Summary

Problems solved by technology

A large amount of solid waste will be generated during the demolition process. If it is not handled properly, the solid waste will not only occupy a large amount of land and seriously affect the city appearance, but also cause many safety hazards if piled up randomly. At the same time, there are many reusable resources in the solid waste. Including many non-renewable resources, such as reinforced concrete, etc.

[0003] At present, many cities have begun to pay attention to the recycling and treatment of solid waste, and have continuously updated many corresponding policies. However, due to technical difficulties, the efficiency of solid waste recycling and treatment is low, and the recycling rate is low.

However, solid waste is often piled up during the treatment process, and it is difficult to effectively identify and separate solid waste. Therefore, an efficient and reliable solid waste identification scheme is urgently needed
