　　Umbrellas are daily necessities for people. Everyone should have the experience of buying umbrellas. But have you really understood umbrellas when you buy them? Do you think you can choose an umbrella? Is the umbrella you choose suitable for you? Do you know what to pay attention to when choosing an umbrella? Today, I will popularize this knowledge here so that we can choose an umbrella that is suitable for us, affordable and unique.So, I believe carbon fibre umbrella In the future, it will be promising to create a miracle belonging to the industry. https://topumbrella.cc/

　　

　　umbrella quality

　　

　　The quality of the ribs:

　　

　　determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

　　

　　The density of the umbrella cloth:

　　

　　The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

　　

　　Straight-pole umbrellas are more durable:

　　

　　Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

　　

　　Turn the top of the umbrella to see the tightness:

　　

　　Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

　　

　　Turn the umbrella to test the handle:

　　

　　Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

　　

　　Folding and pulling trial:

　　

　　The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.

　　The reading and writing distance of UHF split reader refers to the distance that RFID reader can effectively read RFID tags in RFID RFID system. How far is the reading distance of UHF split reader? The reading distance of UHF is generally 3-5 meters, and the farthest can reach 15 meters. The split reader can be connected with multiple antennas, and it can read a longer distance if the antennas are connected. The specific reading distance is influenced by many factors, including but not limited to the power of the reader, the gain of the antenna, the types and characteristics of RFID tags and environmental factors. The following is a detailed analysis of the factors affecting the reading distance of UHF split reader.in fact industrial rfid reader manufacturers It is more and more welcomed by our customers, and its market performance is gradually improving. https://www.vanchrfid.com/

　　

　　Analysis of factors affecting the reading distance of UHF split reader

　　

　　1. Reader power

　　

　　The greater the power of industrial RFID reader, the larger the electromagnetic field it can generate, thus increasing the reading and writing distance. For example, the maximum output power of some UHF readers can reach 30 dBm (or higher), which determines the upper limit of their reading and writing distance to some extent.

　　

　　2. Antenna gain

　　

　　Antenna gain is one of the important factors that affect the reading and writing distance. The greater the antenna gain, the greater the intensity of the electromagnetic field generated by the reader in a specific direction, thus increasing the reading and writing distance. According to the reference article, the reader equipped with 8dBi antenna can reach the reading and writing distance of 0~20 meters for ordinary tags.

　　

　　3. Types and characteristics of RFID tags

　　

　　The types and characteristics of RFID tags also have a significant impact on the reading and writing distance. Theoretically, the larger the size of RFID tags, the more distant UHF readers can read them.

　　

　　4. Environmental factors

　　

　　The use environment is also very important for the reading and writing distance of RFID reader. Metals and liquids have great influence on UHF performance. Therefore, if it is used in metal objects or working environments with many metal influences, it is necessary to use metal-resistant electronic tags, so as to reduce the influence of metals on tag data signals and facilitate the normal use of RFID electronic tags.

　　

　　Industrial RFID reader

　　

　　ANDEAWELL UHF split reader RU5321M&T-S04 can be connected with four antennas to work at the same time, which is convenient for distributed installation and deployment of antennas.

　　Optical fiber sensor is a kind of sensor that uses optical principle to detect physical quantities. It uses optical fiber as sensing element, transmits optical signal to the detection end through optical fiber, and realizes the measurement of the measured physical quantity by detecting the change of signal. Optical fiber sensor has the advantages of small size, strong anti-interference ability and high reliability, and has been widely used in modern industry, military and medical fields.In order to grow rapidly, optical cable Do not hesitate to change the strategy and rearrange the products, so as to obtain unexpected results. https://www.fibercan-network.com/

　　

　　The working principle of optical fiber sensor is based on the transmission characteristics of optical fiber and optical sensing technology. Usually, an optical fiber sensor consists of a light source, an optical fiber, a detector and a signal processor. The light source generates an optical signal with a certain wavelength, which is transmitted to the detection end through the optical fiber. After being received by the detector, the optical signal is converted into an electrical signal, which is analyzed and processed by the signal processor to obtain the numerical value of the measured physical quantity.

　　

　　optical fibre sensor

　　

　　In optical fiber sensor, the transmission characteristics of optical fiber play a key role in measuring accuracy and reliability. The transmission characteristics of optical fiber are influenced by fiber material, fiber structure and light source. Shi Ying glass or plastic is generally used as the material of optical fiber, and its refractive index and attenuation coefficient determine the transmission speed and attenuation degree of optical signals. The structure of optical fiber includes single-mode fiber and multimode fiber, and the light transmission mode inside is different, so different types of optical fiber can be selected for different application requirements. The choice of light source will also affect the transmission characteristics of optical fiber, such as the wavelength and power of light source and other parameters will affect the transmission distance and intensity of optical signals.

　　

　　In addition to optical fiber transmission characteristics, optical sensing technology is also one of the keys of optical fiber sensors. Optical sensing technology uses the interference, scattering and absorption of optical signals to measure the measured physical quantities. For example, fiber optic gyroscopes use the interference principle of optical signals to measure the rotation angle; Optical fiber temperature sensor uses the thermal scattering effect of optical fiber materials to measure temperature; Optical fiber pressure sensor uses the pressure sensitivity of optical fiber to measure pressure.

　　

　　Optical fiber sensors are widely used. For example, in the industrial field, optical fiber sensors can be used to measure physical quantities such as pressure, temperature, displacement and vibration, and can be used in machinery manufacturing, petrochemical industry, aircraft, automobiles and other fields. In the medical field, optical fiber sensors can be used in cardiovascular surgery, endoscopic surgery and so on. In the military field, optical fiber sensors can be used in missile guidance, radio interference detection and so on. In the field of scientific research, optical fiber sensors can be used in earthquake monitoring, meteorological detection and other fields.

　　

　　Another important feature of the application of optical fiber sensor is that it can realize remote measurement. The signal of optical fiber sensor can be transmitted to a remote location through optical fiber for measurement and monitoring. This characteristic can realize the measurement of dangerous environment and inaccessible places, such as deep sea and space. In addition, optical fiber sensors can realize multi-point and distributed measurement, and connect multiple sensors together to realize real-time monitoring of large structures.

　　

　　Although optical fiber sensors have broad application prospects and high technical advantages, there are still some problems to be solved in practical application. For example, the signal transmission distance of optical fiber sensor is limited, and the signal attenuation and distortion need to be considered; The sensitivity and accuracy of optical fiber sensor need to be further improved to meet higher measurement requirements; The cost of optical fiber sensor is high, so it is necessary to find a technical solution to reduce the cost.

　　

　　In a word, optical fiber sensor is a kind of high-precision sensor based on optical principle, which has a wide application prospect and technical advantages. In the future development, we can expect the emergence of more advanced optical fiber sensor technology to meet higher measurement requirements and practical application requirements.

　　PCB, namely printed circuit board, is one of the important parts of electronic industry bar. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards are used to electrically interconnect the components. Printed circuit board (PCB) is composed of insulating bottom plate, connecting wires and pads for assembling and welding electronic components, which has the dual functions of conducting lines and insulating bottom plate. It can replace complex wiring and realize the electrical connection between components in the circuit, which not only simplifies the assembly and welding of electronic products. Below, Shenzhen Lianxiaobian will take you to understand the meaning of each layer of PCB.Only by working together can we turn pcb assembly manufacturer The value of the play out, the development of the supply market needs. https://intechcircuit.com/

　　

　　There are many layers used in PCB design in PCB factory: mechanical layer, keepout layer forbidden wiring layer, Signal layer signal layer, Internal plane layer internal power/grounding layer, top overlay screen printing layer, bottom overlay screen printing layer, Top paste top flux layer, bottom paste bottom flux layer, top solder top solder resist layer, bottom solder bottom solder resist layer, drill guide via guide layer, drill drawing via drilling layer, and multilayer.

　　

　　Top signal layer (Top Layer):

　　

　　Also known as component layer, it is mainly used for placing components, and can be used for wiring for double-layer boards and multi-layer boards.

　　

　　Intermediate signal layer (Mid Layer):

　　

　　There can be up to 30 layers, which are used for laying signal lines in multilayer boards.

　　

　　Bottom signal layer:

　　

　　Also known as welding layer, it is mainly used for wiring and welding, and sometimes components can be placed.

　　

　　Top overlay:

　　

　　It is used to mark the projection outline of components, the label, nominal value or model of components and various annotation characters.

　　

　　Bottom overlay:

　　

　　Same as the top screen printing layer, if all kinds of labels are included in the top screen printing layer, then the bottom screen printing layer is unnecessary.

　　

　　Internal Plane plane:

　　

　　It is usually called the inner electrical layer, including the power supply layer, the reference power supply layer and the ground plane signal layer. The internal power layer is output in the form of negative film.

　　

　　Mechanical Layer (mechanical layer):

　　

　　The mechanical layer defines the appearance of the whole PCB, and it is generally used to set the external dimensions, data marks, alignment marks, assembly instructions and other mechanical information of the circuit board.

　　

　　Altium Designer provides 16 mechanical layers, which are generally used to set the overall dimensions, data marks, alignment marks, assembly instructions and other mechanical information of the circuit board. This information varies according to the requirements of design companies or PCB manufacturers. In addition, the mechanical layer can be attached to other layers to output the display together.

　　

　　Solder mask (solder mask):

　　

　　Altium Designer provides two solder resist layers: Top Solder (top layer) and Bottom Solder (bottom layer).

　　

　　There are two layers of Top solder Mask and Bottom Solder Mask, which are automatically generated by Protel PCB corresponding to the data of pads and vias in circuit board files, and are mainly used for laying solder resist paint. This board adopts negative output, so the pads and vias displayed on the board represent the areas on the circuit board that are not covered with solder resist paint, that is, the parts that can be soldered.

　　

　　Because it is a negative output, in fact, the actual effect of the part with Solder Mask is not green oil, but tin plating, which is silvery white! Apply a layer of paint, such as solder mask, to all parts other than the pad to prevent these parts from being tinned. Solder resist is used to match pads in the design process and is automatically generated.

　　

　　Solder mask is the solder mask, which refers to the part of the board to be painted with green oil. In fact, this solder mask uses negative output, so after the shape of the solder mask is mapped to the board, it is not the green oil solder mask, but the copper skin is exposed. Usually, in order to increase the thickness of copper skin, the solder mask is crossed to remove green oil, and then tin is added to increase the thickness of copper wire.

　　

　　Apply a layer of paint to all parts outside the pad. We usually use green oil and blue oil to prevent these parts from being tinned. Solder resist is used to match pads in the design process and is automatically generated. The solder mask is a negative output, the solder mask is not covered with oil, and the other parts are covered with oil.
