Emergency logistics monitoring method based on optimal emergency network selection

Abstract

The present invention relates to an optimal emergency network point selection-based emergency logistics monitoring method. According to the method, spectrum sensing modules and spectrum sensing fusion modules which work cooperatively are arranged on vehicles; the normalized confidence indexes, emergency indexes and normalized power consumption indexes of the spectrum sensing modules and normalized speed influence factors which affect the detection performance of the spectrum sensing modules are obtained; priority indexes which characterize the performance of the spectrum sensing modules in mobile states can be obtained; spectrum sensing modules which participate in collaborative detection are selected through the priority indexes; high detection performance of the selected spectrum sensing modules and the accuracy of the detection of frequency band states in the surrounding communication environments of optimal emergency vehicles are realized; and communication modules on the optimal emergency vehicles can accurately switch to work on idle frequency bands, so that an emergency logistics scheduling and supervision center can perform remote real-time monitoring on emergency materials on the optimal emergency vehicles.

Description

technical field [0001] The invention relates to the field of logistics management, in particular to an emergency logistics monitoring method based on optimal emergency network selection. Background technique [0002] Emergency logistics refers to the special logistics activities of emergency scheduling and transportation of materials in response to emergencies such as severe natural disasters, public security incidents, and military conflicts. [0003] When extremely serious natural disasters such as earthquakes, mudslides, and typhoons occur, the National Disaster Prevention Command Center will allocate vehicles from all over the country to deliver emergency supplies to the disaster-stricken centers. Under the background of the above special emergency environment, the disaster prevention command center needs to integrate all the idle vehicles of the social logistics company to quickly transport the emergency supplies to the disaster center at the first time, and monitor the...

AI Technical Summary

Problems solved by technology

[0004] In an emergency environment, spectrum resources will be blown out, resulting in paralyzed damage to the existing wireless communication environment and emergency logistics management system, resulting in the inability of the disaster prevention command center to monitor the emergency supplies on vehicles smoothly and in real time situation, ultimately resulting in delays in the safe delivery of emergency supplies to affected centers where emergency supplies are needed
