Discussion on the Scheme of Vehicle Container Security Inspection Machine

With the rapid development of global trade, container transportation, as an important component of modern logistics systems, is increasingly valued for its safety and efficiency. However, with the continuous increase in container transportation volume, traditional security inspection methods are no longer able to meet the increasingly stringent safety requirements. Therefore, as an efficient and accurate security inspection equipment, vehicle container security inspection machines have gradually become essential equipment in major logistics parks, customs, ports, and border ports. This article will delve into the technical solutions and applications of vehicle container security inspection machines.



1、 Basic principles of vehicle container security inspection machine

The vehicle container security inspection machine mainly uses the principle of X-ray radiation imaging. The fan-shaped radiation emitted by the radiation device penetrates the enclosed carriage and its loaded goods, and is received by the detector installed on the other side. Due to differences in the absorption of X-rays by different objects, the signal intensity output by the detector will also vary. After image processing, these signals can generate contour and shape related images of the loaded items on the vehicle, which can be displayed on the computer screen. By viewing these images, operators can quickly determine whether there are illegal prohibited or dangerous goods inside the container.

2、 Key technical parameters of vehicle container security inspection machine

1. Detector and Accelerator

Vehicle container security inspection machines typically use high-performance scintillation detector arrays and electron linear accelerators as core components. These devices ensure high penetration and resolution of radiation, enabling precise detection of items inside containers.

2. Penetration and Resolution

The penetration power of a security check machine is one of the important indicators to measure its performance. For example, some security screening machines can penetrate 300mm thick steel plates and clearly display the outline of 200mm x 200mm x 100mm lead blocks. At the same time, its spatial and penetrating wire resolution are also very high, able to distinguish steel wires that penetrate 100mm thickness and 2.8mm thickness, ensuring the accuracy and meticulousness of detection.

3. Contrast sensitivity and substance identification

The security check machine also has high contrast sensitivity, which can clearly display subtle items hidden behind thick steel plates. In addition, it can distinguish between organic and inorganic substances and label them with different colors (such as blue for inorganic substances and orange for organic substances), allowing operators to quickly identify suspicious items.

4. Radiation safety and protection

Radiation safety is an important consideration in the design of security screening machines. Modern security screening machines are usually equipped with safety interlock devices, emergency stop buttons, radiation monitoring instruments and other safety protection devices to ensure the safety of operators and the public. At the same time, the absorbed dose and annual effective radiation dose of a single scan are controlled within a safe range to reduce potential impacts on personnel health.

3、 Application scheme of vehicle container security inspection machine

1. Fixed security inspection machine

Fixed security screening machines are usually installed in fixed locations such as logistics parks, customs, ports, etc., to conduct security checks on incoming and outgoing vehicles. This security check machine has the characteristics of fast scanning speed and high detection accuracy, and can achieve comprehensive inspection of items inside containers. At the same time, it can also be integrated with license plate recognition systems, electronic tag recognition systems, etc., to improve overall security inspection efficiency.


2. Mobile security check machine

Mobile security screening machines are more flexible and suitable for temporary checkpoints or places that require frequent location changes. It usually adopts a vehicle mounted design and has the ability to deploy and withdraw quickly. Mobile security inspection machines also have the characteristics of high penetration and high resolution, which can meet the security inspection needs in various complex environments.

3. Remote inspection mode

Modern security screening machines also support remote inspection mode. In this mode, the perspective image of the inspected vehicle will be transmitted to the central monitoring room for interpretation and decision-making by the operator located in the central monitoring room. This mode not only improves the efficiency of security checks, but also reduces the safety risks for on-site operators.

4、 Market prospects of vehicle container security inspection machines

With the continuous development of global trade and the increasing prosperity of the logistics industry, the market demand for vehicle container security inspection machines will continue to grow. Especially in key areas such as customs, ports, and border ports, security screening machines have become an important tool to ensure national security and smooth trade. In the future, with the continuous advancement of technology and the expansion of the market, vehicle container security inspection machines will play an important role in more fields.



5、 Conclusion

As an important component of modern logistics system, the technical level and application effect of vehicle container security inspection machine are directly related to logistics safety and efficiency. By continuously optimizing technical solutions, improving detection accuracy and safety, vehicle container security inspection machines will play a more important role in the future. At the same time, with the continuous growth of market demand and technological progress, the security inspection machine market will also usher in broader development prospects.
