Bar code scanning module: magical technology power

The history of the development of bar scanning module is not a special factory, but its influence is not small, and now many of the various electronic devices in our lives have its figure, it is like the eyes of science and technology, through the identification of bar codes, quickly and accurately obtain information, in order to improve our work efficiency.

Bar code module is a device that reads and decodes one-dimensional or two-dimensional bar codes, usually composed of light source, lens, photoelectric converter, signal processor and other parts. When the bar code scanning module is aligned with the bar code, the light source will emit light to the bar code, the reflected light is focused through the lens to the photoelectric converter, the photoelectric converter converts the optical signal into an electrical signal, and then decoded by the signal processor to obtain the information represented by the bar code.

The form of barcode scanning module is mainly divided into two types: embedded type and fixed type.
The embedded bar code module can be integrated into a variety of OEM equipment and its installation configuration, which directly integrates the scan code engine on the motherboard of the terminal equipment, such as tablet, handheld, etc. The standard serial TTL-232 interface is used to connect the terminal device, which can not only save additional hardware costs and space occupation, but also improve the stability and reliability of the terminal device, so that it can identify the bar code more quickly and accurately. Increase efficiency.

Most of the fixed bar code scanning modules are packaged, with a strong shell, so the level of protection is high, the installation position is relatively flexible, can easily adapt to a variety of equipment and application environment, a little obvious, that is, the overall structure is more beautiful and generous, installation is more flexible, more suitable for access control equipment, vending machines, self-service ordering machines and other self-service terminals. Moreover, it can also support a variety of working modes, such as induction reading, command triggering, steady on mode, etc. Connected with intelligent terminal through RS-232 serial port or USB interface, it greatly expands its application range and meets different needs.

According to the China Electronic Technology Data report, the market size of bar code scanning equipment in China has increased by nearly 30% in the past five years, and is expected to maintain stable growth in the next few years. This is enough to prove the wide application and importance of bar code scanning modules in modern society.

Of course, although the application of the bar code module is very extensive, but the people who really understand it are not many, only know that there is this thing, in fact, the working principle of the bar code scanning module is not complicated, it mainly relies on optical imaging and image processing technology. However, to design a bar code scanning module with excellent performance, good stability and strong adaptability, it is necessary to have a deep understanding of these technologies, while also taking into account factors such as cost, volume and power consumption.

With the continuous development of science and technology, in the future, the bar code module will be more intelligent, efficient, accurate, and can bring more convenience to our lives, no matter what kind of scanning scene or reading needs, can cope with, and with continuous exploration, so that the bar code scanning module can better serve the society.
