Emergency logistics management system and method for obtaining goods state information

Abstract

The invention relates to an emergency logistics management system and method for obtaining goods state information. The system comprises an emergency logistics management center platform, goods with RFID tags and a freight vehicle. The goods are located on the freight vehicle, the freight vehicle is provided with at least three frequency band detection modules, a relay module, a GPS positioning module, a Beidou navigation positioning module, a WIFI module, an LTE communication module, an RFID reader, a storage and a central processing module, the goods are provided with micro-processing chips, pressure sensors and infrared sensors, and the emergency logistics management center platform is connected with the central processing module. The frequency band detection modules are used for detecting current communication frequency bands, and the LTE communication module is adjusted to perform communication on an idle frequency band , so that cooperative positioning data of the GPS positioning module, the Beidou navigation positioning module and the WIFI module or target goods mark states are sent to the emergency logistics management center platform to be managed, and emergency logistics management work in emergency communication environments is achieved.

Description

technical field [0001] The invention relates to the field of logistics management, in particular to an emergency logistics management system and method for acquiring cargo status information. Background technique [0002] In recent years, with the development of wireless communication technology and the increase in the number of base station layouts, people have become more dependent on the application of wireless communication technology. Wireless communication technology is not only deeply integrated into people's life, study and work, but also profoundly affects all aspects of social management, traffic control and social security. The development and maturity of communication technology has given people's activities, social management, The normal operation of economic activities has brought great convenience, and it has also facilitated logistics management activities that promote economic activities. However, when special emergency events occur, such as earthquakes, mu...

AI Technical Summary

Problems solved by technology

In the special environment of emergency or wartime, the spectrum resources will be blown out, causing the existing wireless communication environment and emergency logistics management system to suffer paralyzed damage, resulting in the disaster prevention command center or the logistics department of the military region being unable to real-time , Accurately understand the current status information of emergency supplies and military supplies, which delays the normal progress of emergency plans
