Agricultural product supply network node identification method, agricultural product supply network node identification device and electronic equipment

Abstract

The invention discloses an agricultural product supply network node identification method and device and electronic equipment, and belongs to the field of trajectory data mining, and the agricultural product supply network node identification comprises the steps: obtaining the trajectory data of a heavy diesel vehicle, and identifying the effective stop point of the trajectory data; constructing a travel chain of the heavy diesel vehicle according to the effective stop points, semantizing the travel chain, and extracting an agricultural product freight travel chain; constructing an agricultural product supply network based on the agricultural product freight travel chain; and determining a function role of the agricultural product supply network node according to the agricultural product supply network. The method effectively solves the problem that current agricultural product supply network research is mostly carried out based on static statistical data and cannot depict the flow process of agricultural products in real time and finely, and can provide reference for supply guarantee and transportation route design and optimization of the agricultural products.

Description

technical field [0001] The present application belongs to the technical field of trajectory data mining, and in particular relates to a method, device and electronic device for identifying a node of an agricultural product supply network. Background technique [0002] With the acceleration of domestic urbanization, population growth and the development of agricultural modernization, the importance of agricultural trade in food supply is increasing. By reflecting the flow of trade, the agricultural product supply network provides a guarantee for scientifically regulating agricultural resources, stabilizing and optimizing the agricultural product supply chain, and promoting the coordinated development of regional trade. At the same time, by identifying the functional roles of different urban nodes in the agricultural product supply network, it can provide a new perspective for understanding agricultural product supply patterns. [0003] At present, a grain flow network is con...

AI Technical Summary

Problems solved by technology

The current agricultural product supply network research based on static statistical data (commodity order data, production and sales data, etc.) can only consider the interaction between origin and destination, ignoring the intermediate interaction process of agricultural product supply, resulting in the inability to identify different The functional role of cities in the supply network makes it difficult to describe the flow process of agricultural products in real time and in detail
