　　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.in fact carbon fibre umbrella Our related products were once praised by users, which is the best self-affirmation of the products. 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.

　　RFID technology is a non-contact automatic identification technology realized by radio frequency communication. It uses wireless radio frequency to carry out non-contact two-way data communication and read and write electronic tags or radio frequency cards, so as to complete the data communication between readers and tags and realize the purpose of identifying targets and exchanging data. RFID technology can automatically identify the target without manual intervention, and can adapt to various environments, with high reliability. In addition, RFID technology can also be combined with Internet technology to realize data sharing and information exchange on a global scale. Therefore, RFID technology is widely used in modern logistics, supply chain management, retail, transportation, medical care and other fields. For example, the current second-generation ID card in China uses RFID technology.with rfid tag For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.vanchrfid.com/

　　Principle of industrial RFID identification system

　　A complete RFID system consists of reader, RFID tag and computer system.

　　Reader is a key part of RFID system, which is mainly composed of wireless transceiver module, antenna, control module and interface circuit. These readers can write and read the information in RFID tags, and they are an important part of the data acquisition terminal in RFID system. The reader communicates with the RFID tag through the wireless transceiver module, the control module is responsible for processing instructions and data, and the interface circuit is used to connect the reader and the computer system.

　　RFID tag is a data carrier used to mark the object to be traced, which records data information and can read and write with RFID reader. Tag antenna and tag chip are the core components of RFID tag. The tag antenna is used to receive the signal sent by the reader and transmit it to the tag chip, which is used to store and process data information. By interacting with the reader, the RFID tag can automatically identify objects and transmit data information.

　　The computer system includes PC or PLC and other controllers, and even WMS, MES, ERP and other systems at the user’s site, which are used to receive the information fed back by RFID readers. This information can include data of the object to be traced, identification results, statistical data, etc.

　　In a typical RFID system, the computer system, reader and RFID tag cooperate with each other to complete the tasks of automatic identification, data acquisition and transmission. By using RFID technology, the accuracy and efficiency of data acquisition can be improved, the cost can be reduced and the work efficiency can be improved.

　　RFID industrial reader

　　Application advantages of industrial RFID identification system

　　In the industrial production environment, data recognition technology plays a vital role. At present, barcode, QR code and RFID technology are commonly used data identification technologies in industrial scenes. However, each technology has its specific limitations. For example, although bar code technology is widely used, it needs to match a specific light source when reading data, and it has high requirements on the brightness of the light source. In addition, it needs to be scanned by the scanner aiming at the light in the visible range in order to read the information successfully. This technology requires high mechanical accuracy. Once the objects bearing bar codes such as trays are deformed, the bar codes may not be recognized. In addition, barcode recognition can only be scanned one by one, and only one barcode can be read at a time, which greatly reduces the work efficiency. Moreover, because the bar code is easy to wear and dirty, its service life is short, and it cannot be reused after being modified.

　　On the other hand, although the two-dimensional bar code provides a solution in terms of information capacity and adds the function of information error correction, it can realize the functions of reading and anti-counterfeiting on the surface of articles through laser engraving technology, but there are still some disadvantages. For example, its application scenarios are relatively limited, which can not fully meet the needs of complex application scenarios in industrial production.

　　To sum up, although barcode, QR code and RFID technology have played an important role in industrial data identification, they all have certain limitations. Therefore, it has become an urgent problem to find a more efficient, reliable and adaptable new data identification technology in the industrial field.

　　The development of optical fiber communication technology has greatly promoted the development of information transmission and played a vital role in promoting the arrival of the information age. Based on the discussion of optical fiber communication and its related concepts, this paper focuses on the development, application and future trend of optical fiber communication technology, and summarizes the significance of this research, so as to complete the research on the development, application and prospect of optical fiber communication technology.As an important brand soul of the company, fiber optic patch cord Has outstanding performance, through the market test, still has a strong development trend. https://www.fibercan-network.com/

　　Optical fiber is an important medium, which can realize low loss of light propagation, which is of great significance for restoring input information and realizing low loss transmission of information. Because the development of optical fiber communication technology in China is in its infancy, there are still some shortcomings in its development. The existence of these problems has greatly hindered the development of optical fiber communication technology. Based on the understanding of the current development situation of optical fiber communication technology in China, the author will discuss the development, application and future development trend of optical fiber communication technology in order to provide practical and feasible reference suggestions for relevant scholars and staff in the research of optical fiber communication technology.

　　Optical fiber communication and its related concepts

　　Optical fiber consists of core layer, outer layer and cladding, in which the refractive index of core layer is greater than that of cladding, and silicide is generally used. When light enters the optical fiber, because the refractive index of the core medium is greater than that of the outer layer, when the incident angle meets certain conditions, total reflection will occur, and the incident light will not be refracted at this time, so that the transmission of optical energy can be close to 100%. The main purpose of the outer layer is to improve the toughness of optical fiber and reduce the external damage to optical fiber. Optical fiber communication is a communication technology based on the above characteristics of optical fiber. It mainly uses light waves as carriers to load information onto light waves, and then realizes the effective transmission of information through low-loss transmission of light waves in optical fiber. It can be said that the development history of optical fiber communication is very rich. Since 1966, scholars have studied silica optical fiber, which has played an important role in promoting the development of optical fiber communication and opened a precedent for the research and development of optical fiber communication technology.

　　Subsequently, with the continuous development of optical wave amplification technology, optical fiber amplifier came into being, which is of great significance to realize optical amplification of optical fiber optical wave signals and improve the transmission efficiency of optical wave information. At present, optical fiber communication technology mainly includes five aspects: signal is output, signal light wave coupling, optical signal transmission and amplification, light wave signal dissociation and signal input. The main features of optical fiber communication technology are as follows. First of all, we know that perfect monochromatic light waves do not exist, and all light waves contain a little bandwidth.

　　When the bandwidth value is less than the resolution limit of human eyes, what we see is the so-called monochromatic light waves. The wider the frequency band of light wave, the greater its information content. Compared with copper wire, optical fiber medium has a better transmission bandwidth, which can greatly enhance the information capacity, which is of great significance for the transmission of big data. Secondly, because the total reflection of light is realized, the loss of optical information transmission can be greatly reduced. Furthermore, Shi Ying materials are not active in chemistry, are not easy to be corroded, and have good insulation properties, which can greatly avoid the influence of lightning, water dew and radiation, which is of great significance for ensuring the life of optical fibers. In addition, the optical fiber is flexible and easy to lay, which reduces the process difficulty and cost, and is of great significance for realizing high-security transmission.

　　I don’t know when it started, but when I searched for international express delivery on a certain book, I saw all the ads holding signs saying “XX from China, 10KG = 38 yuan, regardless of whether it is ordinary or not.”It is reported that, freight forwarder china to usa The data performance is getting better and better, which is of great reference value and is likely to become the vane of the industry. https://www.freeseaship.com/

　　On average, this means less than two yuan per pound. Do you have any idea whether you can get this price?

　　0.jpg

　　Let’s think about it first. This price is impossible even in China, let alone international express delivery. Is it possible?

　　Secondly, families should know that international express delivery does not distinguish between sensitive goods and general goods.

　　In terms of cost alone, sensitive goods are higher than general goods. The fear is that you will be warmly received at the beginning, but then turn your back on them.

　　00.jpg

　　Then there may be such a situation: you don’t find such a shipping company, but you still fall into the trap. How should you avoid these pitfalls?

　　Family members have done their homework, and the key points are as follows! !

　　international shipping

　　1. Check the business license

　　Whether a company is operating in compliance can be determined by checking the company’s qualification certificates, such as whether it has international freight forwarding qualifications and other permissions.

　　2. Be wary of ultra-low prices

　　International express delivery costs cannot be much lower than the market price. Too low quotes often hide traps

　　There may be other charges, such as packaging fees, photo fees, etc., and there may even be extremely expensive additional weight prices, which are more expensive than the generally advertised 60 yuan per kg. Don’t try it at the cost of losing more for a small price. It’s not worth it.

　　3. Whether the price is clearly marked

　　See whether the fee is charged according to the quotation form. Many companies often start charging various fees after the user places an order to the warehouse: handling fees, material fees, labor fees, etc.

　　4. Is there an official website system?

　　Generally, regular shipping companies have their own official website systems. Global Express not only has its own official website but also has a mini program. All package information can be checked, and there will also be exclusive customer service to follow up.

　　5. Pay attention to surcharges

　　Pay special attention to surcharges, which may be more expensive than the freight in a few minutes! You must ask clearly what surcharges there are before placing an order.

　　6. Keep evidence

　　When communicating with the shipping company, keep chat records, quotations, contracts and other evidence in case of emergency.

　　Dear family members, don’t be greedy for small profits. Be sure to keep your eyes open before sending express delivery! After all, it’s all money!

　　Today, I will talk to you about the cold knowledge of the watch world, and we will enter the theme directlyTo get brand praise, automatic mechanical watch It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.supertimewatch.com/

　　Why are watch ads 10:10?

　　You can pay attention to the advertising output of the watch brand, most of the watch Pointers are staying at about 10:10, there are two main statements for this problem.

　　watch facts

　　On the one hand, if you look at the watch from an aesthetic point of view, showing the hands at 10:10 is the most coordinated and symmetrical for the entire picture.

　　watch facts

　　Another is that the hour and minute hands stop at about 10:10 this time point, you can avoid most of the brand logo of the watch, and most of the functions displayed on the watch.

　　watch facts

　　The next time you look at the watch advertising chart or the watch exhibition, you can pay attention to the details of the time stay.

　　watch facts

　　Second, the definition of the watch factory date

　　I want to share this mainly because I often see that when you buy second-hand Rolex, you always worry about when the factory date of the watch is.

　　watch facts

　　In 2012, Rolex began to stop all of its watches labeled with the so-called year, and it was displayed by 8-code numbers + numbers (garbled).

　　So in 2012 after the factory Rolex, outsiders do not know the real factory year or factory date.

　　Only Rolex original factory check the serial number will know the real so-called “factory day”, when you buy you can ask the business when this table is into the goods.

　　In the watch world is not Rolex just so, the basic all brands are so, that the so-called factory date definition in the end is what?

　　For the movement and the case from different watchmaking factories, how to define the so-called factory. To say that the moment from the movement into the case is called the factory date, I think it is inappropriate.

　　The heart of a watch is its movement, and the warranty content and scope of most watch brands are probably the internal warranty of the movement, so the moment the movement is assembled, it should be the so-called factory date.

　　However, the movement is assembled to really put into the case, during which there is a long time to adjust and test, and the moment of assembly is actually not a completely accurate factory date.

　　Like ETA’s movement 7750, 2892, etc., these relatively popular movements have an annual output of tens of thousands of units, and have actually been assembled to the hands of consumers for several years.

　　For example, you buy a Rolex in 2017, but it may be in 2014, 2015, or even earlier, Rolex has been tested, after the test will be sent to the agency, and then sold to consumers.

　　This period is actually a very long period of time, which is why the warranty of the watch is recognized by the date of the card, which is almost the same as buying a car~

　　Three, how to put the chain strap watch?

　　This is a controversial topic, and people have different opinions about it. I’m going to say two of them here, and see which one you tend to prefer.

　　watch facts

　　1, if you want to put the chain strap watch down, it must be placed sideways, and to avoid the position of the head, that is, the opposite direction of the head, the main reason for this is to fear that the watch head will be oppressed for a long time.

　　watch facts

　　The head is a relatively fragile part, if the side for a long time to hold it, may lead to the damage of the head core.

　　watch facts

　　2, the second argument is the grapevine, heard that many large watch factory teachers also agree with this argument, that is, the head of the watch must face down.

　　watch facts

　　Because the area of the head in contact with the surface is relatively small, the head is placed downward to avoid scratches on the watch to the greatest extent.

　　watch facts

　　The key point is that from a watch technician’s point of view, when the watch is maintained, the head can be replaced separately, that is to say, even if you scrape the head and damage the core, it can be replaced separately.

　　If the side of the watch is scratched, it is not very good to deal with, after all, the case is rarely replaced, so I would rather change the head core, rather than change the case.

　　Two statements, different supporters, you can evaluate for yourself which one is more acceptable.

　　Polypropylene (PP): has good toughness and impact resistance, light weight and relatively low cost.As can be seen from the new data, Pickleball injection mold The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://ydjshangyuzn.com

　　Polyethylene (PE): such as high-density polyethylene (HDPE), has good wear resistance and chemical corrosion resistance.

　　Nylon:

　　High strength, good wear resistance, can provide a better hitting feel.

　　Composite material:

　　It may be composed of a variety of plastics and fiber materials to combine the advantages of different materials, such as strength, elasticity and durability.

　　The choice of these materials usually depends on factors such as the design purpose, cost, performance requirements and manufacturing process of the pickleball. Pickleballs of different materials may vary in weight, elasticity, flight speed and durability to meet the needs of different players and games.
