X-ray Inspection Machines

X-ray  Inspection Machines

Security machine is a kind of electronic equipment that utilizes X-ray scanning and imaging technology to carry out security fluoroscopic inspection of baggage, parcels and other cargo items. In the era of high-tech exceptionally developed and constantly updated, the security machine has become a public security field of essential safety inspection equipment. The following is a brief introduction to the working principle of the security machine, product types and specific applications:

Working principle and product type

Ray imaging technology: security machine through the X-ray scanning to see through the goods, X-rays are a kind of high-energy electromagnetic waves, has a strong penetrating ability, can penetrate wood, cardboard, leather and other opaque objects.

Penetration and absorption: When X-rays penetrate the inspected object, different substances absorb X-rays to different degrees, thus forming an image. The degree of absorption of X-rays by the object determines the degree of black and white of the image, which in turn helps to identify the nature of the object.

Image Processing: X-rays received by the detector are converted into electrical signals, which are then converted into images by image processing software for analysis by security personnel. Different substances are shown as different colors in the image, e.g. organic substances are shown as orange, books, ceramics, etc. are shown as green, and metals are shown as blue.

Automatic image storage: the system provides automatic image storage for subsequent analysis.

Common Product Types of Security Screening Machines

Channel-type screening machine: applicable to airports, stations and other places with heavy traffic, used to check baggage and parcels.

Portable screening machine: easy to use in some special occasions or temporary inspection.

Fixed, handheld and mobile: from the mechanical structure point of view classification, security screening machine including fixed for fixed location of the security check, handheld easy to carry and move, and mobile can be used in a certain range of mobile.

Large security machine, medium-sized security machine, small security machine: according to the size of the channel and the application of different scenarios, the security machine has a large, medium and small different models to adapt to different occasions on the size of the items of the security check needs.

Explosives detector: security check instrument and equipment specialized in detecting explosives, quickly and accurately find people carrying explosives by detecting the gas composition in the air. Widely used in airports, stations and other high-risk areas, characterized by fast detection speed and high accuracy.

Low-energy security machine and multi-(high)-energy security machine: according to the X-ray penetration power of high and low division, multi-energy security machine penetration is stronger, applicable to public security, law enforcement, stations, customs and other important places, and low-energy security machine is suitable for occasions with low requirements.

Typical application scenarios

Airports and aviation hubs: for checking passengers and carry-on items to ensure flight safety.Train and subway stations: to check passengers and baggage and ensure the safety of public transportation.Important events and stadiums: to check entrants and carry-ons to ensure the safety of event participants.Government agencies and important places: such as government buildings, courts, military facilities, etc., for security checks of entering persons.Border checkpoints and customs: to check incoming and outgoing persons and goods to prevent the inflow of smuggled and illegal goods.Postal and courier services: to inspect parcels and letters to ensure that mailed items do not contain dangerous or prohibited items.Critical infrastructure: such as nuclear power plants, hydroelectric power plants, chemical plants, etc., to ensure the safety of incoming personnel and goods.

The main performance parameters of the security machine daily operation and maintenance include the following aspects:

Channel size , conveyor speed, maximum load capacity, penetration, resolution, radiation safety, X-ray generator, image processing system, working environment, noise monitor size and so on. The daily operation and maintenance of the security machine need to pay attention to the following issues:Professional and technical personnel to operate, equipment damage to stop the operation, to prevent the entry of body parts, to prevent the inflow of liquid, heat sinks and displays must not be blocked, to avoid standing near the entrance and exit of the channel, regular cleaning of the detector and the X-ray source, to avoid dirt affecting the quality of the image and so on.

The use of security screening machines must follow the relevant international laws and regulations

Civil airport equipment management regulations: According to the “Civil Airport Equipment Management Regulations”, airport equipment should comply with national standards and technical specifications, in line with the principle of safety, application, energy saving, environmental protection. Airport equipment that has not been inspected and qualified by the airport equipment inspection organization recognized by CAAC shall not be used in civil airports. Non-airport security screening equipment must also comply with the principles of safety inspection, radiation protection training and safety management, etc.
