The emergence of the code scanner has brought convenience to many fields, especially the two fields of payment and logistics, because the code scanner has undergone tremendous changes, and the core of the code scanner is actually a small code scanning module, it is not insignificant, but the function can not be ignored.
Code scanner is the so-called bar code reader, which is a device that reads bar code information, its working principle is not very complicated, that is, through the photoelectric converter to convert the black and white stripes on the bar code into electrical signals, and then decoder the electrical signals to decode, so as to obtain the data information expressed by the bar code. The scanning module is responsible for the conversion of optical signals to electrical signals.
The type of scanning module is not much, and it is generally divided into optical department and laser department according to different applications.
The optical scanning module mainly emits light through the infrared light source, illuminates the bar code, and then receives the reflected light through the photoelectric receiver, converting it into an electrical signal, such modules have low cost, low power consumption, but the relative identification distance is short, and the quality of the bar code and the environment will be relatively high.
The laser scanning module uses a laser light source to emit a laser beam, irradiate it to the bar code, and then receive the reflected laser beam through the photoelectric receiver to convert it into an electrical signal. It is different from the optical scanning module in that it has high recognition accuracy and long recognition distance, and the relative cost will be relatively high.
Scanning module plays an important role in many fields, helping to improve the management efficiency of the supply chain and reduce costs, and with the continuous development and maturity of technologies such as the Internet of Things and big data, scanning module may also continue to play a strong role in new fields such as smart home, unmanned retail, etc. I believe that in the future two-dimensional code module will be more accurate and lower power consumption. It will also shine in a wider field.
The scanning module is the important core of the scanner, responsible for converting the optical signal into an electrical signal, so as to achieve the reading of bar code information, it plays an important role in different fields, can improve efficiency and reduce costs, looking forward to the scanning module in the future will be more widely used, for our daily life to bring more convenience.
