　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.In addition to domestic, walk through metal detector It has also emerged in the international field and gradually gained the favor of more foreign friends. https://secuzoan.com/

　　How does the security inspection machine work?

　　

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　

　　security check

　　

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

What Is a Swimming Pool Air Source Heat Pump

　　The swimming pool heat pump is an air source heat pump designed by the air energy manufacturer specifically for swimming pools. Its working principle is the same as that of ordinary air source heat pumps. The difference between the two is:Only by working together can we turn heat pumps for sale The value of the play out, the development of the supply market needs. http://mangoenergyheatpump.com

　　Ordinary air source heat pumps are mainly used for domestic hot water heating, while swimming pool air source heat pumps are dedicated to constant temperature heating of swimming pools. The heat exchanger is made of special pure titanium tubes with good corrosion resistance. Because swimming pools need to be cleaned by adding chemicals, ordinary heat pumps will quickly corrode the heat exchanger. In the past, swimming pools liked to use coal/gas/oil, electric boilers and other equipment to provide hot water, but in recent years, with the country’s attention to environmental protection and other issues, coupled with the shortcomings of coal/gas/oil, electric boilers and other equipment themselves, such as unsafe, high pollution and high cost, more and more swimming pools and swimming pools have begun to choose new hot water equipment to provide hot water for swimming pools. Among them, swimming pool air source heat pumps have become the object of constant temperature pursuit of villa swimming pools, swimming pools, and fitness clubs.

　　

　　What are the advantages of swimming pool air source heat pumps?

　　

　　1. Safe, environmentally friendly and pollution-free. No coal or oil is consumed, so there is no need to worry about coal prices or fire or explosion safety issues. Moreover, there is no pollutant emission to the environment during use, no environmental pressure, and it meets national environmental protection requirements. There is no need to face annual inspections by boiler-related departments.

　　

　　2. It is more energy-efficient and saves more money. The heating efficiency of ordinary air-energy heat pumps is generally 400%, which is four times that of ordinary electric water heaters. However, because the swimming pool air-energy heat pump can control the temperature at only 28＜C, which is lower than the outlet water temperature of ordinary air-energy heat pumps, the heating efficiency is as high as 520%, which is more energy-efficient.

　　

　　3. Accurate temperature control and more comfortable. The air-energy swimming pool constant temperature system has a wider temperature operation range (ambient temperature range -25-43＜C, water temperature control range 20-55＜C), and can automatically adjust the flow rate according to ambient temperature, water temperature and other data to ensure stable and efficient operation of the unit. And it is not affected by natural climate such as wind, light, rain, and snow, and can achieve constant temperature of the swimming pool throughout the year.

Brief Introduction of PIR Sensor

　　In order to achieve the goal, motion detector sensor Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. https://www.sunlit-tech.com

　　PIR sensor (Passive Infrared Sensor) is a passive infrared sensor. It is widely used in consumer products such as doorbells, cat eyes, induction switches, night lights, and security because of its low power consumption, low price, and simple use.

　　

　　

　　(1) PIR detection principle

　　

　　PIR also has another alias, which is pyroelectric infrared sensor. Its detection principle is the pyroelectric effect, that is, the phenomenon that a substance will generate electric charge when the temperature changes. The normal human body temperature is 36-37 degrees, and the infrared radiation released is about 9-10um. The detection wavelength range of pir motion detector is generally in the range of 5-14um. That is, within the detection range of PIR, if there is an energy change of 5-14um wavelength, the PIR sensor will generate a current change, thereby giving a trigger signal. It should be noted here that PIR detects energy changes, not infrared radiation of a fixed wavelength. If an object with a fixed wavelength is not moving, PIR will not detect it.

　　

　　(2) Advantages of PIR

　　

　　Low power consumption, typical power consumption is about 10uA

　　

　　Low price, ranging from one or two yuan to five or six yuan

　　

　　Easy to use, the simplest one only needs to detect a pin level signal

　　

　　(3) PIR classification

　　

　　There are many types of PIR motion detector, which can be roughly divided into the following ways:

　　

　　Enablement controllable: switchable PIR

　　

　　Output signal type: digital PIR and analog PIR

　　

　　Is the sensitivity adjustable: adjustable PIR and non-adjustable PIR

　　

　　Sensitivity adjustment method: hardware adjustment and software programming adjustment PIR

　　

　　

　　(4) PIR selection

　　

　　When selecting a PIR sensor, we generally need to consider the following basic requirements: voltage range, operating current, number of pins required, data output format, whether the sensitivity is adjustable, structural package size, and compatibility with the Fresnel lens. Another important consideration is cost. Without considering cost, it doesn¨t matter whether you choose a model or not. Just choose the best one. In actual product development, especially for consumer products, prices are very sensitive. Basically, all bosses want to use the cheapest device and debug it to achieve the best effect, especially for products with large shipments. If you don¨t have high requirements for product quality, it doesn¨t matter. If you have strict requirements for product quality and performance, you need to be very careful when selecting a model to avoid replacing the device when you find that it does not meet the requirements in the later stages of the project.
