Abstract

The invention relates to explosive material logistics tracking and discloses a radioactive nanometer microballoon and GPS navigation-based explosive material logistics operation trajectory tracking system. The system comprises the following modules: a vehicle-mounted radio isotope detector information processing module used for receiving and processing explosive material position information sentvia a radio isotope detector and a computer interlocking information processing module used for receiving and parsing information sent via an interlocking device. Based on radioactive nanometer microballoons and GPS navigation, the system can be used for trajectory tracking and safety status monitoring in a full logistics operation period in an all-weather manner; the system is characterized by high precision, low detecting limit, low cost, high safety, long service life and the like; a problem that via conventional explosive material monitoring, low efficiency is caused and explosive identities can be removed easily can be solved; all position information of explosive materials in circulation links can be obtained remotely in a distributed manner, and new means can be provided for monitoring a safety status of the explosive materials in real time.

Description

technical field [0001] The invention relates to explosive logistics tracking, in particular to an explosive logistics trajectory tracking system based on radioactive nano-microspheres and GPS navigation. Background technique [0002] Hazardous chemicals need to be strictly managed in all aspects of production, storage, circulation and use. In recent years, the illegal use of hazardous chemicals has been increasing, and terrorist incidents have attracted more and more attention from governments. How to find a practical way to manage the production of hazardous chemicals, organize or track the illegal circulation and use of hazardous chemicals, and quickly detect terrorist cases is an urgent problem that security agencies in various countries need to solve. [0003] Because radionuclides can continuously emit rays with certain characteristics; through radioactive detection methods, the position of markers containing radionuclides and the movement changes of their quantities c...
