　　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

　　ZA5030A

　　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.

　　What is a Geothermal Heat Pump?

　　A geothermal heat pump is a system that leverages the earth’s natural heat to provide heating, cooling, and often hot water for residential and commercial buildings. Unlike conventional HVAC systems that rely on outside air temperatures, geothermal systems use the relatively constant temperature of the ground as a heat source in winter and a heat sink in summer.

　　How Do Geothermal Heat Pumps Work?

　　1. Ground Loop System:

　　Closed-Loop Systems: These are the most common and involve a loop of piping buried in the ground or submerged in water. The loops can be installed horizontally, vertically, or in a pond/lake.

　　Open-Loop Systems: These systems use groundwater from a well or surface body, which is returned to the source after heat exchange.

　　2. Heat Exchange Process:

　　Heating Mode: During winter, the fluid in the ground loop absorbs heat from the earth. This heat is then transferred to the heat pump unit inside the building. The heat pump compresses the absorbed heat to a higher temperature and distributes it through the building’s ductwork or radiant heating system.

　　Cooling Mode: In the summer, the process is reversed. The heat pump extracts heat from the indoor air and transfers it to the cooler ground via the ground loop. This removes heat from the home and effectively cools it down.

　　3. Distribution System:

　　Once the heat is extracted from the ground and conditioned by the heat pump, it is distributed throughout the home via traditional ductwork or a radiant floor system.

　　Benefits of Geothermal Heat Pumps

　　1. Energy Efficiency:

　　Geothermal heat pumps are significantly more efficient than traditional heating and cooling systems. They can achieve efficiencies of 300-600%, meaning they can produce 3 to 6 units of heating or cooling for every unit of electricity consumed.

　　2. Environmental Impact:

　　By using renewable energy from the earth, geothermal systems reduce reliance on fossil fuels and decrease greenhouse gas emissions. They are a greener choice for sustainable living.

　　3. Cost Savings:

　　Although the initial installation cost of a geothermal heat pump can be higher, the system pays for itself over time through lower operating costs. Homeowners can save up to 70% on heating, cooling, and hot water bills.

　　4. Longevity and Durability:

　　Geothermal systems have fewer moving parts and are sheltered from outdoor elements, leading to longer lifespans. The underground loop systems often come with warranties of 50 years or more.
