Method, device and system for inspecting moving object based on cosmic rays

A device for inspecting a moving object based on cosmic rays, comprising a hardware processor configured to implement:

• a speed detection module configured to detect whether a speed of the inspected moving object is within a preset range;
• a recording module configured to record a motion trajectory of the inspected moving object with a monitoring device, wherein the monitoring device comprises combination of any one or more of:
• a thermal imager, a camera, a pressure sensor, and an optical sensor;
• an acquiring module configured to acquire information about charged particles in the cosmic rays with a position sensitive detector, the information about charged particles comprising track information of the charged particles, wherein the track information of the charged particles comprised in the information about charged particles and information of the moving object are iteratively updated in real time;
• a matching module configured to determine the moving object by matching positions of the motion trajectory and the track information;
• a reconstruction module configured to reconstruct the track of the charged particles according to the information about the charged particles;
• and
• a recognition module configured to recognize the material inside the moving object based on the track reconstruction,
• wherein the matching module is further configured to:
• analyze a time difference between an incident time and an emission time of the track information of the charged particles;
• and
• match the time and position of the track information of the charged particles and the motion trajectory of the moving object according to an incident position, an emission position of the track information of the charged particles and the analyzed time difference.
