Welcome to ShenZhen Masung Intelligent Equipment Co.,Ltd
A barcode is a graphic that records information about data symbols, which are distributed on a plane with a specific geometry and according to a certain pattern. In encoding, barcodes cleverly use the concept of "0" and "1" bitstreams that form the basis of the computer's internal logic. Several geometries corresponding to binary are used to represent alphanumeric information, which is automatically read by image input equipment or photoelectric scanning equipment to realize automatic information processing. 2D barcode has some commonalities of barcode technology, namely, each code system has its specific character set, each character occupies a certain width, has a certain verification function, and so on. At the same time, the barcode also has the function of automatically recognizing the information of different rows and handling the rotation change point of graphics. Shenzhen Masung Intelligent Equipment Co., Ltd. always adheres to the enterprise spirit of "dedication, innovation, integrity, and service" and actively creates a unique private enterprise culture atmosphere. It is currently expanding the proportion and scope of intelligent manufacturing based on its representative product, i.e. barcode scanner, and gradually expanding its R&D and sales areas.
What are the technical support of the barcode scanner?
How to determine the resolution of the barcode scanner?
Common barcode scanners usually use the following four technologies, namely light pen, CCD, laser, and image red light.
The light pen is the first hand-held contact barcode scanner, and it is also the most economical bar code reader. When in use, the operator needs to contact the light pen with the bar code surface and send out a small light spot through the lens of the light pen. When this light spot crosses the bar code from left to right, the light in the white part will be reflected, while the light in the black part will be absorbed. Therefore, a variable voltage is generated inside the light pen, which is used for decoding after amplification and shaping.
CCD is an electronic coupling device, which is more suitable for close-up and contact scanning. The CCD scanner uses one or more LEDs, and the light emitted can cover the whole bar code. The image of the bar code is transmitted to a row of light, sampled by each photodiode, and each bar or space is distinguished by the adjacent detection result of "black" or "white", to determine the character of the bar code.
The laser scanner is relatively expensive among various scanners, but it can provide the highest functional indicators, so it is widely used in various industries. The hand-held laser scanner emits a beam of light through a laser diode and shines on a rotating prism or a swinging mirror. The reflected light shines on the surface of the bar code through the reading window, and the light returns to the reader after being reflected by the bar or empty. It is collected and focused by a mirror and converted into an electrical signal through the photoelectric converter. The signal will be decoded by a scanner or decoding software on the terminal.
Image red light barcode scanner is a barcode reader that can replace laser guns and has excellent code reading performance. The unique image design makes its decoding ability very strong. The bar code can not be read by the general scanner, but the image red light can still be read easily. Its rich data editing function can make the image red light scanner fully cooperate with the user's existing software.
The resolution of the barcode scanner should be determined from three aspects: the optical part, hardware part, and software part. In other words, the resolution of the barcode scanner is equal to the resolution of its optical components plus the resolution obtained by its processing and analysis through hardware and software.
Optical resolution refers to the actual number of light points that can be captured by the optical components of the barcode scanner per square inch. It refers to the physical resolution of the CCD (or other photoelectric devices) of the barcode scanner and the real resolution of the barcode scanner. Its value is obtained by dividing the pixel points that can be captured by the photoelectric element by the maximum horizontal scanning size of the barcode scanner. After computer software and hardware processing, the output image will become more realistic and the resolution will be higher. At present, most barcode scanners sold on the market have the function of software and hardware expansion of resolution. When scanning an image, the higher the scanning resolution is set, the finer the effect of the generated image, the larger the generated image file, but the more interpolation components.
Nowadays, the 2D barcode is widely used. As long as enough user groups are cultivated and combined with a good business model, the 2D barcode will become one of the most powerful tools to connect reality and the virtual. If you have been engaged in barcode scanning-related fields, you may consider choosing our cost-effective products.
Transactions in modern society involve multi-agent games. The process for consumers to choose high-quality printers seems simple, but in fact, consumers need to have deep market consumption literacy. So, how should consumers choose a label printer?
Here is the outline:
1.Why buy a label printer?
2.How to buy a label printer?
3.What are the advantages of label printers?
1.Meet the needs of consumers to efficiently print labels. For all kinds of businesses that need to print labels in batches, nothing can better meet the needs of consumers than specialized printing equipment. In addition, such specialized equipment can also help consumers get rid of the difficulty of choosing paper material and label size.
2.Ensure smooth use. The biggest difference between a high-quality printer and an ordinary printer is its internal structure. High-quality printers use advanced technology, which can effectively prevent the machine from jamming and pulling paper. In this way, consumers can use it more smoothly and efficiently, and can also better improve their work efficiency of consumers.
3.Reduce maintenance costs. Consumers spend far more than the economic cost to buy a printer, but also include time cost, energy cost, and many other aspects. A high-quality machine can allow consumers to enjoy a longer service life in subsequent use, and consumers can also enjoy lower maintenance costs.
1.Respect consumer preferences. Consumers are individuals with independent consciousness and usage preferences. Therefore, sensible consumers should start from their actual needs and find products that can meet consumers' label printing needs and meet consumers' specific emotional needs.
2.Do more product comparisons. The speed of various printers, applicable label sizes, and printing effects are all product parameters that consumers can compare. Only when consumers compare more printer products can they more effectively find printers that satisfy them in the market.
3.Choose the right partner. An unpleasant cooperation experience is a kind of harm to both parties. Therefore, consumers need to select suitable producers as partners according to their market performance.
1.Specialized printing machines. Few products in the market can simultaneously meet the diverse needs of consumers. As a result, sensible consumers are more inclined to trust producers who have specialized in production for a long time.
2.Convenient operation. Consumers can easily complete the installation and use of the printer just by referring to the graphic instructions in the product manual. Moreover, all the doubts encountered by consumers in use can be answered in detail by viewing the instructions on the product details page or by consulting customer service.
In short, a high-quality label printer can bring consumers a great improvement in work efficiency. Shenzhen Masung Intelligent Equipment Co., Ltd is a Chinese enterprise that has been producing and selling all kinds of printing equipment for many years, and we are confident to take the leading position in the comparison of similar products.
Under the strong leadership of the CPC Central Committee, the situation of domestic epidemic prevention and control continues to improve. However, at present, the international epidemic continues to spread, and the risk of epidemic re-introduction into China and causing a new round of spread continues to exist. In some places, there are continuous imported related cases, and even a number of clustered epidemics. The task of consolidating the achievements of epidemic prevention and control, and "importing from outside and rebounding from inside" is very arduous. We should fully understand the complicated situation of current epidemic prevention and control, cherish the hard-won results of prevention and control, and constantly consolidate the situation of continuous improvement.
Under the prevention and control of normalized epidemic situation, the whole world should actively build complete measures of comprehensive prevention and control system. MASUNG, as the technical guarantor of health code epidemic prevention, specially launched a series of self-developed new "health code epidemic prevention verification products". The MS-2104 of Masung Toka is a self-help development scheme in European health green code, which identifies the green certification of the European Union digital ID card coid-19, and includes a series of epidemic prevention and control terminal devices such as health code scanning device (MS-2104 health code module). It has fast verification speed and high accuracy, can efficiently screen out abnormal situations, and can scan health codes (local provincial codes/national government platform health codes) by swiping ID cards. Automatically checked health code status, 14-day trip, results and vaccination information, and mobile phone scanning code are no longer necessary items, thus solving outstanding epidemic prevention difficulties such as the inconvenience of the elderly, children and other groups to show their mobile phone health codes.
The two-dimensional code module MS-2104 of Masung Toka supports data analysis such as health code identification and verification (green code, yellow code, red code), face temperature measurement, reading health code, 14-day dynamic travel inspection, etc. It has good demonstration significance, can be promoted nationwide, and is convenient for people to travel under normal prevention and control. Scan health code, temperature and code scanner should be widely used to reduce offline contact and enhance contactless travel.
