X-ray Imaging Control for Moving Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for imaging inspection of moving objects with high energy rays are costly and have slow response speeds, leading to inefficient inspection times due to mechanical control of high energy ray emission.
Innovation Solution
A system comprising a first detecting unit to identify the moving object, a second detecting unit to determine when a part to be shielded has passed through, and a control system to control a scan imaging device that uses a microwave system and electron beam emitting device to rapidly emit X-ray beams after the object and shielded part have been detected, allowing for rapid and safe inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical block plate is used to control the emission of high energy rays, then the device can shield rays when needed, but the response speed is slow and the inspection time is long
Solution Approach 1:
The patent replaces the mechanical block plate system with an electronic control system that manages the accelerator's operation states (off-state, warm-up state, and imaging state). This substitution eliminates mechanical moving parts and enables faster response to control signals, directly resolving the contradiction between reliable ray shielding and fast response speed.
2Reliability
If the accelerator continuously emits high energy rays with constant frequency, then the imaging can be performed, but the inspection time is long and the vehicle inspecting efficiency is low
Solution Approach 1:
The patent implements periodic action by dividing the accelerator operation into distinct states (off-state, warm-up state, and imaging state) that are activated in sequence based on vehicle detection. The accelerator emits high energy rays only during the imaging state when a vehicle is present, rather than continuously, thereby maintaining imaging quality while significantly improving inspection efficiency and reducing unnecessary radiation exposure.
Solution Approach 2:
The system performs preliminary detection of vehicle presence using detection units before activating the accelerator for imaging. This preliminary action allows the system to prepare and activate the accelerator only when needed, optimizing the balance between maintaining reliable imaging and improving overall inspection productivity.
3Reliability
If the accelerator is continuously on to ensure imaging capability, then imaging can be performed at any time, but the device cost is high
Solution Approach 1:
The patent implements periodic operation of the accelerator with distinct states (off-state, warm-up state, and imaging state), activating the expensive accelerator component only when imaging is actually needed rather than keeping it continuously on. This reduces overall device cost while maintaining reliable imaging capability when required.
