　　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.

　　Car warning lights, also known as emergency vehicle lights, play a critical role in vehicle safety by alerting drivers to potential issues and hazards.

　　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.

　　Every item in life needs careful maintenance, and your pillow is no exception. Let’s take a look at the maintenance methods of memory foam pillows with Xiao Shi!In addition to these aspects, travel pillow memory foam The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://tainengjikang.com/

　　How to maintain a memory foam pillow?

　　1. Pillowcase

　　Memory pillows usually have outer and inner covers. The inner cover is mostly made of pure cotton fabric, while the outer cover is generally made of velvet fabric. The inner cover can be machine washed or hand washed, and can be dried after being wrung out. It is generally recommended to hand wash the velvet outer cover, and do not wring it too hard when drying. When installing the pillow core, pay attention to the direction of the big and small heads. Most memory pillows are now B-shaped, which cannot be cut open and installed upside down.

　　2. Pillow Core

　　(1) Memory pillows are generally made of environmentally friendly polyurethane. This material will turn yellow if left in the sun for a long time, so the pillow core should not be exposed to the sun. Just take it out frequently to ventilate and dry naturally.

　　(2) Another thing to pay attention to when maintaining the pillow core is that you should not press it with force for a long time. When not in use, leave it in its natural state and do not place it under heavy objects for a long time. This may cause the memory foam to deform, making you uncomfortable when sleeping.

　　(3) The pillow core cannot be washed. This type of memory foam has a very unique structure. If moisture enters, it will be difficult to clean out, which will also reduce the quality of sleep. Generally, it is used with a pillowcase and an inner cover. If you accidentally sweat, take out the pillow core and let it dry naturally.

　　Finally, if the newly purchased memory foam pillow has a slight odor, it is normal. Just let it air dry for 3-5 days (if the ventilation is good, the odor can be removed in 2 days), and the odor will be completely gone, and you can use it with confidence.

　　Mold accessories are mainly parts or components installed on the mold. They can be widely used in various plastic molds, stamping molds, automobiles, electrical and aviation manufacturing fields. However, for mold accessories, the better the quality, the longer the life. Therefore, it is a problem that we all pay close attention to to understand the factors that affect the quality of mold accessories. Do you know what factors affect the quality of mold accessories? Hairong Precision introduces you below:In addition to innate advantages, plastic moulding parts Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://www.dghrjmmj.com

　　The factors that affect the quality of mold accessories are as follows:

　　1. Rationality of mold accessory design

　　Mold accessory designers should first fully understand the user’s use requirements and working conditions, and the situation of die-casting force, and then select suitable materials according to the use requirements and working environment, and understand the die-casting performance of the materials. In the design of mold accessories, special attention should be paid to the premise of meeting the use requirements, and the die-casting structure should be as simple as possible. The wall thickness should be appropriately uniform, and the necessary mold slope should be left, otherwise it will cause pits, pores, shrinkage, underpressure, stretch marks, cracks, deformation and other defects on the casting. The requirements for the dimensional accuracy of the casting should be reasonable, otherwise it will bring unnecessary troubles to the mold design, mold processing, process condition formulation and management, and will cause a large number of unqualified products.

　　2. Mold structure, processing accuracy and mold material

　　The selection of mold accessories for die casting is closely related to the product quality of die casting, mold design, processing, mold material selection, etc. If the mold structure is unreasonable, it is difficult for mold accessories to make the product qualified no matter what measures are taken from the process. In addition, the mold material, mold processing accuracy, surface roughness, processing marks, small cracks in heat treatment, nitride layer thickness and mold assembly of heat-resistant and wear-resistant mold accessories will affect product quality and mold life.

　　3. Shrinkage rate of mold accessories

　　The shrinkage rate of casting materials is generally expressed as an average percentage or a percentage of a certain range of variation. The average shrinkage rate of the material is usually selected. For the design of high-precision die castings and molds of mold accessories, special attention should be paid to the selection of material shrinkage. If necessary, the mold can be tested first, the required data can be obtained in the test mold, and then the production quantity of large molds designed and manufactured can be carried out.

　　To sum up, these are the factors that affect the quality of mold accessories. In order to better ensure the quality of mold accessories, we try to choose the best structural solution in the design process. The designer of mold accessories must fully consider the technical requirements and structure of the parts, and must meet the processability and feasibility of mold manufacturing.
