Product Overview

This product is a medium-sized channel-type X-ray security inspection system specially designed for high-flow and large-size item safety inspection, emergency disposal of explosion-related and dangerous cases, and evidence collection at criminal scenes. It is also the core technical equipment in anti-terrorism and explosive ordnance disposal (EOD), contraband inspection, and criminal scene investigation. Relying on the penetration imaging characteristics of X-rays, the equipment realizes fast and non-destructive internal structure imaging inspection of checked luggage, parcels, cartons, involved containers, etc. With the large-size inspection channel of 800mm (width) × 650mm (height), excellent imaging resolution and strong penetration ability, it provides key technical support for the screening of suspicious items at the scene of explosion-related and dangerous cases, on-site search of major criminal cases, and normalized security inspection of key places. The system can clearly restore the internal structure, material properties and spatial form of the inspected items, and assist security inspection, investigation and EOD personnel to accurately identify contraband and key physical evidence such as explosive devices, weapons, controlled appliances, drugs, smuggled goods, stolen property involved in the case, and crime tools. It is the core special equipment for building a public security defense line and improving the efficiency of criminal search and evidence collection and personnel safety guarantee.

Technical Principle

The core of the equipment works based on the principle of X-ray penetration attenuation imaging, adopting a top-down X-ray emission structure, which can realize full-coverage and dead-angle-free imaging detection of the inspected items. The X-ray generator on the top of the system emits fan-shaped beam wide-pulse X-rays, which penetrate the measured object conveyed by the conveyor belt at a constant speed. Because the atomic number and density of different materials (metal, plastic, liquid, organic matter, explosives, ceramics, etc.) inside the object are different, the absorption and attenuation coefficients of X-rays are significantly different, resulting in differential attenuation of the intensity of X-rays after penetrating the object. The differential ray intensity signal is completely received by the high-sensitivity detector array at the bottom of the equipment, and converted into digital electrical signals in real time. After being processed by the high-speed data acquisition system and AI image processing unit, a grayscale image or material classification pseudo-color image reflecting the internal structure, density distribution and material properties of the object is generated on the monitor of the operation terminal. Finally, the non-destructive detection purpose of accurately insight into the internal condition of the inspected items without opening the package, contacting or disturbing is realized, which perfectly adapts to the non-destructive pre-inspection of involved physical evidence in criminal investigation and the non-contact preliminary judgment of suspicious items in EOD work.

Core Functions and Compliance Practical Value

The equipment adopts a large channel size and high-flow design. The cross-sectional size of the inspection channel is 800mm × 650mm, which is compatible with the inspection needs of most conventional suitcases, trolleys, parcel cartons and medium-sized involved containers on the market. The rated running speed of the conveyor belt is 0.22m/s, and the rated load is 170kg, which can support continuous and efficient assembly line inspection operations. It can not only meet the high-flow normalized security inspection needs of large-scale events, transportation hubs and key places, but also adapt to the fast non-destructive preliminary screening of a large number of involved physical evidence and seized items by the criminal investigation department, greatly improving the work efficiency of item inspection.

The equipment has industry-leading high-definition imaging capability and strong penetration performance. The spatial resolution can reach the level of 0.101mm diameter metal wire, which can clearly identify the fine metal parts in the explosive device, the blade structure of the controlled knife, and the subtle characteristics of the drug package. Even the contraband with complex camouflage and multi-layer packaging can be accurately identified. The maximum steel plate penetration can reach 34mm, which can effectively penetrate thick metal boxes, composite packaging, and densely stacked items, clearly present the shape, position and structural relationship of substances with different densities hidden inside, eliminate the occurrence of missed detection and false detection, and provide reliable image basis for the disposal of explosion-related cases and contraband inspection.

The equipment is designed in strict accordance with national radiation safety standards, with extremely high use safety and environmental protection performance. The single inspection radiation dose is strictly controlled below 1.5µGy, which is completely safe for films with sensitivity below ISO1600, photosensitive physical evidence and biological evidence. It will not cause any damage to the inspected involved physical evidence, nor will it cause health hazards to the surrounding operators and inspected personnel. The X-ray generator adopts a sealed oil-cooled structure, which can support 100% continuous operation in the full working cycle. The ray leakage dose around the equipment is lower than 0.05µGy/h, which is far lower than the national radiation safety limit, fully complying with the relevant management regulations of the Regulations on the Safety and Protection of Radioisotopes and Ray Devices, and eliminating the occurrence of radiation safety accidents from the hardware level.

The whole machine adopts industrial-grade stable design, with strong environmental adaptability and reliable operation capability. Equipped with a high-performance network transmission module, it supports remote monitoring, image storage, data backtracking and centralized management, which can perfectly adapt to the docking needs of the integrated security and law enforcement handling platform of the public security system. The working temperature range of the equipment covers 0℃ ~ 45℃, which can adapt to various use scenarios such as indoor fixed security check points, temporarily built outdoor security check points, and temporary deployment at the case scene. The maximum power consumption of the whole machine is only 1.0KW, and the operation noise is less than 65dB. It can operate stably in the environment without a dedicated machine room, with convenient installation and deployment, and can quickly complete the equipment erection and start-up in emergency scenarios.

Compliant Application Scenarios

This equipment can only be used in a standardized manner within the scope of authorized law enforcement by units with statutory law enforcement authority and radiation safety license qualifications. The core compliant application scenarios include five categories: First, anti-terrorism EOD and emergency disposal of sudden dangerous events. In the emergency disposal of suspected explosive alarms, explosion-related intimidation cases, and major sudden public events, fast, non-contact and non-disturbing non-destructive screening of suspicious parcels, luggage and containers is carried out to preliminarily judge whether there are dangerous items such as explosive devices, detonating components, hazardous chemical containers, weapon parts inside, providing key image basis for the formulation of EOD disposal plans and case nature judgment, and maximizing the protection of the life safety of EOD personnel and on-site personnel. Second, inspection of drugs, contraband and smuggled goods. In the investigation of customs border ports, logistics express hubs, postal sorting centers, and drug cases, inspect the inbound and outbound goods, express mails, transportation luggage, and involved parcels, identify contraband such as drug lumps, powder packages, gun parts, controlled knives, and smuggled goods hidden in the interlayer and camouflage packaging through image features, providing key clues and evidence for case investigation and contraband inspection. Third, on-site search and evidence collection of major criminal cases. In the on-site search of major criminal cases such as intentional homicide, robbery, theft, gang-related and evil-related cases, non-destructive inspection is carried out on locked suitcases, sealed containers, and involved parcels found in the suspect's residence, warehouse, and vehicle, to quickly find key physical evidence such as crime tools, stolen money and goods, crime records, and involved documentary evidence that may be hidden inside, avoid pollution and damage of physical evidence caused by blind unpacking, and guide investigators to carry out targeted unpacking evidence collection and physical evidence fixation. Fourth, pre-inspection of involved physical evidence in criminal investigation laboratories. For sealed parcels, unknown containers, and involved seized items that need to be sent to the criminal technology laboratory for inspection, non-destructive pre-inspection is first carried out through X-ray machine to understand the layout, material and nature of the internal items in advance, avoid pollution, damage and accidental trigger of biological evidence, trace physical evidence and explosive devices that may be caused by direct unpacking, and plan the optimal physical evidence extraction and inspection plan to ensure the safety and standardization of physical evidence inspection work. Fifth, security inspection for large-scale events and key vital parts. As the core equipment of fixed or temporary security check points, it carries out full-coverage safety inspection on personnel luggage and items entering the core areas of major events, important meetings, vital parts of party and government organs, and densely populated places, strictly prevent the inflow of dangerous items such as guns, explosives, and controlled appliances, build a public security defense line, and ensure the safe and orderly operation of major events and key places.

Practical Application Cases

The Anti-Terrorism Detachment of the Municipal Public Security Bureau received an alarm that a commercial square received an anonymous explosion-related intimidation message, saying that multiple explosive devices were placed in the square. At the same time, the property management of the square found 3 unclaimed suspicious trolleys in the underground parking lot, and the on-site situation was urgent. After the EOD personnel rushed to the scene, in order to avoid direct contact with the suspicious trolleys triggering the explosive device, they immediately deployed this medium-sized channel-type X-ray security inspection machine, and carried out non-contact non-destructive imaging inspection on the 3 suspicious trolleys in the temporarily built safe area at the scene. Through the high-definition pseudo-color images generated by the equipment, the EOD personnel clearly identified the structure of the items in the luggage. Among them, 2 trolleys contained ordinary clothes and daily necessities, and 1 trolley found structures such as batteries, timers, wires, and black powder packages suspected of explosive devices, which completely matched the typical image characteristics of explosive devices. According to the X-ray imaging results, the EOD personnel accurately formulated the EOD disposal plan, successfully carried out the safe dismantling and harmless disposal of the suspected explosive device. At the same time, the technical personnel locked the production characteristics of the device through the image details, providing key clues for the subsequent case investigation. Finally, the criminal suspect who made, placed the explosive device and released the intimidation information was successfully arrested. The rapid deployment capability, high-definition imaging performance and non-contact inspection characteristics of this equipment provided an indispensable technical support for the safe disposal of this explosion-related incident and the rapid detection of the case.
The Criminal Investigation Detachment of the Municipal Public Security Bureau investigated a series of cross-regional burglary cases. The suspect fled to many places to commit more than 20 crimes within half a year, with a huge amount of money involved. The investigators locked the hiding residence of the suspect through video tracking, and legally searched the residence. During the search, the investigators found 6 locked trolleys and iron boxes in the bedroom wardrobe. The suspect refused to provide the unlock password and explain the contents of the boxes. Forcible demolition may cause damage and loss of the involved physical evidence in the boxes. The investigators immediately called this medium-sized channel-type X-ray security inspection machine, and carried out non-destructive imaging inspection on the 6 locked boxes at the search scene. Through high-definition X-ray images, they clearly identified that 3 of the boxes hid a large number of stolen money, gold jewelry, watches and other stolen items involved in the case, and the other 3 boxes hid lock picking tools, technical unlocking equipment, gloves, hoods and other crime tools, as well as notebooks recording the crime process. According to the X-ray imaging results, the investigators safely opened all the boxes with the cooperation of professional lock pickers, and completely fixed all the involved stolen goods and crime tools, forming a complete evidence chain. In the case of zero confession, relying on the stolen goods, crime tools and X-ray imaging evidence seized at the scene, all the criminal facts of the suspect were successfully locked, and the series of cross-regional burglary cases were solved. The non-destructive inspection capability of this equipment provided a key guarantee for the complete fixation of the involved physical evidence and the smooth investigation of the case.
