Double twelve refers to December 12 every year, is a shopping carnival day.

This year, "Double Twelve" is renamed as "Year-end Good Price Festival", and many merchants will launch various promotions to attract consumers to shop. Many people will shop online to enjoy various discounts and promotions.

Initially, "Double Twelve" originated in China, but now it has become a worldwide shopping carnival.

So what is the secret behind the logistical magic of such shopping sprees?

The secret behind logistics magic:

The logistics magic of Double Twelve does not come out of nowhere, but after a long period of preparation and planning. In anticipation of the year-end shopping frenzy, major e-commerce platforms and logistics companies will make full preparations in advance. They will increase their warehousing facilities and manpower, and stock up in advance to cope with the surge in the number of orders. In addition, they will optimize their logistics networks and improve delivery efficiency to ensure that orders can be delivered in a timely manner.

The logistics magic of Double Twelve cannot be separated from the support of advanced science and technology. In the modern logistics industry, a variety of advanced technical means are widely used to improve logistics efficiency and service quality. With the rapid development of science and technology, barcode technology has gradually become an excellent choice for item identification. Barcode technology is not only a kind of information storage and transmission technology, it can quickly and accurately identify items, significantly reduce the error rate of data collection, and is more capable of enhancing work efficiency, reducing labor costs, simplifying business processes, and improving supply chain logistics efficiency. Logistics companies will use big data analytics and artificial intelligence technology to perform intelligent scheduling and route planning for orders, thereby maximizing distribution efficiency. At the same time, they will also use IoT technology to monitor the transportation of goods in real time to ensure that the goods can be safely delivered to their destinations.

So what is the principle of barcoding?

Principles of barcoding:

The principle of barcodes is based on a coding system called UPC (Universal Product Code), which consists of a series of numbers and characters, usually consisting of 12 numbers. These numbers and characters are encoded as a series of black and white stripes of varying widths, with each number or character corresponding to a particular combination of stripes. In addition to UPC codes, there are many other types of barcodes, such as Code 39, Code 128, QR codes, and so on. Each type of barcode has its own specific encoding rules and application scenarios. For example, QR code can store more information and is suitable for e-payment, mobile applications and other fields.

Barcodes work by reading the width and spacing of the stripes through an optical scanning device, such as an intelligent code scanner. When an item is scanned, the Smart Scanner emits a beam of light through a light source and then receives the reflected light back. Based on the width and spacing of the stripes, the Smart Scanner can recognize the corresponding numbers or characters.

So what supports a smart sweeper to work?

How smart sweepers work:

The working principle of the intelligent code scanner is: when it emits an infrared light source, it will use a specialized chip to decode according to the reflected results and finally return the correct characters represented by the barcode. Its appearance greatly simplifies the process of data entry and information processing, which not only liberates the labor force, but also improves work efficiency and reduces the rate of error codes.

Components of the Smart Sweeper:

1、Housing

The shell of the code scanner is an important part to protect the internal components, which is usually made of plastic or metal materials. The design and quality of the casing not only affects the appearance and aesthetics of the code scanner, but also affects the durability and service life of the code scanner.

2、Light source

The light source of the code scanner is the basis for scanning barcode and 2D code. Generally speaking, there are two kinds of light sources for code scanners: red light and green light. Red light is suitable for most bar codes, while green light is suitable for high-density bar codes and some special 2D codes.

3、Control chip

The control chip is the main controller of the code scanner, which is responsible for controlling the work of the scanning head, processing the scanned information and transmitting it to the computer or mobile device. The performance of the control chip has an important impact on the scanning speed and accuracy of the code scanner gun.

4. Scanning unit

The scanning unit is the core component of the code scanner, which scans the barcode and 2D code by emitting Scanning unit is the core component of the code scanner, which scans barcode and two-dimensional code by emitting light and converts the scanned information into digital signals to be transmitted to computer or mobile device. There are two types of scanning units: linear scanning units and area scanning units. Linear scanning units are suitable for scanning bar codes, while area scanning units are suitable for scanning 2D codes.

Among them, the merit of the wave mirror directly affects the performance of the scanning unit. The wave mirror can optimally delineate the laser beam after passing into a straight line with high stability, excellent straightness, and uniform optical density. In order to safeguard the optical performance of wave mirrors, their surface roughness and face shape PV values need to be precisely inspected.
