With the booming development of cross-border e-commerce, the volume of air cargo continues to rise, and the pressure on cargo security has also increased. Compared with passenger security checks, air cargo security checks have the characteristics of complex cargo types, large batches, and fast turnover, which puts higher demands on the detection efficiency, accuracy, and adaptability of security products. A series of professional air cargo security inspection products have emerged, becoming an important defense line to safeguard cargo safety and ensure smooth logistics.

The core challenge of freight security inspection lies in how to efficiently complete large-scale cargo inspection while accurately identifying hidden dangerous goods. The traditional manual inspection or single box detection mode is no longer able to meet the timeliness requirements of modern air cargo transportation. The large-scale magnetic material rapid screening device developed by Shanghai Miaozhi Technology is an innovative solution for the pain points in this industry. The device adopts the "quantum tunneling effect magnetic resistance array sensor technology" to achieve rapid magnetic detection of whole boards and boxes of goods. It can simultaneously detect hundreds of single boxes in the same container, with a detection time of no more than 20 seconds. Compared with the traditional box by box inspection mode of magnetometer or compass, the efficiency has been improved by 1000 times, and the detection accuracy has reached the level of Nutt. It can accurately identify weak magnetic goods such as Bluetooth speakers and magnetic suction lights, effectively avoiding their interference with aircraft navigation systems. At present, the equipment has been put into use at the cargo terminal of Pudong Airport and has been included in the national standard "Magnetic Test Method for Dangerous Goods", setting a new technical benchmark for the industry.

In addition to magnetic detection products, a series of professional security inspection equipment suitable for freight scenarios are also widely used. The multi view dual energy X-ray security inspection machine solves the problem of identification blind spots caused by overlapping goods through horizontal, vertical and other multi angle imaging. It can accurately distinguish organic, inorganic and mixed substances, and effectively identify dangerous goods such as explosives and flammable materials hidden in the goods. The trace explosive detector uses ion mobility spectrometry technology to analyze particles on the surface of goods, and can quickly identify explosive components such as TNT and RDX. The detection limit is as low as nanograms, providing accurate secondary verification methods for cargo security checks. The collaborative application of these professional products has built a multi-level freight security inspection system of "fast screening+precise review", which not only ensures safety but also considers efficiency.

In the context of global logistics integration, the safety and smoothness of air cargo transportation are directly related to the stable development of international trade. The continuous innovation and application of professional freight security inspection products can not only effectively prevent freight safety risks, but also improve logistics turnover efficiency and reduce enterprise operating costs. In the future, with the continuous upgrading of cargo security inspection technology, more efficient and intelligent security inspection products will be put into use to safeguard the healthy development of the air cargo industry.
