How do security X-ray machines distinguish between explosives, drugs, guns, knives and other dangerou

  As the economy develops more and more, people’s living standards improve and their requirements for security are getting higher and higher. At the same time, due to factors such as wars in the third world, terrorists and extremists, domestic airports, railway stations and mass gathering places are equipped with more and more high-end security equipment.More importantly, put security screening machine It is imperative for us to make thorough analysis and maximize its social function. https://secuzoan.com/

  

  The performance of security inspection equipment has improved a lot compared with previous years. Security inspection X-ray machines are essential equipment for security inspection channels. How this equipment can distinguish dangerous items such as explosives, drugs, guns, knives, etc., we need to start with the principle of security inspection machines.

  

  x-ray machines

  The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

  

  The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

  

  ”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

  

  So how does the security inspection machine detect these dangerous items?

  

  1. Image monitoring method

  

  Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

  

  2. Color analysis method

  

  The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

  

  Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

  

  Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

  

  Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

  

  Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

Harris participated in the presidential campaign against Trump and received high approval ratings

  While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.More importantly, put business bodyguard It is imperative for us to make thorough analysis and maximize its social function. http://huanyubodyguard.com/

 

  

  The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

  

  The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

  

  As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.

What Are the Methods to Prevent Loosening of Anti-loosening Nuts

  Anti-loosening nut is a nut, which is a part that is screwed together with a bolt or a screw for tightening. It is an original part required by all production and processing equipment. Anti-loosening non standard nut is a part that tightly connects mechanical equipment together. With the help of the inner thread, anti-loosening nuts and screws of the same specifications can be connected together. The following is a detailed introduction to several methods of preventing anti-loosening nuts from slipping.In order to open the market, non-standard fasteners price Constantly improve the ability of business development and create an extraordinary brand image for it. https://jieruifasteners.com/

  

  1. Anti-loosening of equipment

  

  It is to use the locking nut stopper to directly limit the relative rotation of the locking nut pair. For example, the use of tooth pins, serial wires and stop washers. Because the locking nut stopper does not have a pre-tightening force, the anti-loosening stopper can only work when the locking nut is loose and returned to the stop position. Therefore, the locking nut method does not actually prevent loosening but prevents falling.

  

  2. Riveting and anti-loosening

  

  After tightening, use punching, welding, bonding and other methods to make the locking nut pair lose the performance of the kinematic pair and the connection becomes an irremovable connection. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be damaged before it can be disassembled.

  

  3. Friction anti-loosening

  

  It is the most widely used anti-loosening method. This method forms a positive pressure between the locking nut pairs that does not change with the external force, so as to form a friction force that can prevent the relative rotation of the locking nut pairs. This positive pressure can be achieved by axially or simultaneously pressing the locking nut pairs in two directions. For example, elastic washers, double nuts, self-locking nuts and insert locking nuts are used.

  

  

  4. Structural anti-loosening

  

  It is to apply the locking nut pair’s own structure, that is, the Tang’s locking nut anti-loosening method.

  

  

  5. Punching edge anti-loosening

  

  After the nut is tightened, the thread is destroyed by punching the end of the thread; bonding anti-loosening generally uses anaerobic adhesive to apply to the thread screw surface. After tightening the anti-loosening nut, the adhesive can solidify by itself, and the actual anti-loosening effect is better. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be destroyed before it can be disassembled.

What are the prerequisites for a security company to become a public company

  In July 2024, a news about the upgrade of the world’s largest security company to a listed company went viral on the Chinese mobile Internet, and many Chinese netizens questioned the information of a security company to become a listed company, believing that it is difficult for a security company to become a real listed company. So, is the information circulating on the Chinese Internet platform true? Is it true that any security company in the world has upgraded to a public company? What are the requirements for a security company to become a public company?In the past ten years, female bodyguard Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. http://huanyubodyguard.com/

 

  

  The listing of the world’s largest security company, reported on the Chinese mobile Internet, could not be confirmed. So far, there are not many international rumors that security companies have become listed companies, and a security company needs to have many listing conditions to become a listed company. Most Chinese security companies are private, small, medium and micro enterprises, which do not have the basic conditions of listed companies. However, this type of security enterprises have indeed played a positive role in promoting the progress of social security. For example, the Huanyu Brothers bodyguard Company in Shenzhen, China, has played a good role in public security supervision in China and countries with many overseas Chinese, and has brought security protection to overseas Chinese groups around the world.

  

  Whether a security company can go public and become a world-class listed company depends on comprehensive conditions. However, the existence of security service companies around the world has contributed greatly to world peace. Since all countries have security service companies, the kidnapping and terrorist attacks of rich people, politicians, stars, network celebrities, celebrities and rich people are decreasing year by year. With private bodyguards in security companies providing security protection services for world celebrities, the security crisis of world celebrities can be lifted.
