We often encounter many difficult technical terms when contacting barcode scanning gun, such as optical resolution, maximum resolution, color resolution, scanning mode, interface mode and so on. Let's know more about barcode scanning gun. It can also be used as a reference when we buy barcode scanning gun. Actually, barcode scanner and barcode reader are the same, but they are called differently.
The common bluetooth laser barcode scanner is composed of light source, optical lens, scanning module, analog-to-digital conversion circuit and plastic shell. It uses optoelectronic components to convert the detected optical signals into electrical signals, and then converts electrical signals into digital signals through analog-to-digital converters and transmits them to the computer for processing. When scanning an image, the light source shines on the image and the reflected light passes through the lens and converges on the scanning module, which converts the optical signal into analog-digital signal (i.e. voltage, which is related to the intensity of the received light), and points out the gray degree of that image. At this time, the analog-to-digital conversion circuit converts the analog voltage into digital signals and transmits them to the computer. The color is quantized by 8, 10 and 12 bits of RGB tricolor, and the signal is processed into the image output of the above bits. If there is a higher number of digits, it means that the image can have more layers and depth, but the color range is beyond the recognition ability of the human eye. So in the range of our resolution, the effect of the bar code scanner with higher digits is that the color cohesion is smooth, and more details of the picture can be seen.
There are many kinds of barcode scanners. The new scanner products already have bluetooth laser barcode scanner. It can connect the barcode scanner with a Bluetooth-enabled mobile phone or PDA, making the data storage and transmission more convenient.
Bluetooth barcode scanner combines PDA or mobile phone with barcode scanner, which not only improves the convenience and efficiency of use, but also saves costs, and makes it more widely used.
Bluetooth is a radio technology that supports short-distance communication (usually within 10m). It can exchange wireless information among many devices, including mobile phones, PDA, wireless headphones, notebook computers, related peripherals and so on. Using Bluetooth technology can effectively simplify the communication between mobile communication terminal devices and between devices and the Internet, thus data transmission becomes more rapid and efficient, and widen the road for wireless communication. Bluetooth adopts decentralized network structure, fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works in the 2.4 GHz ISM (industrial, scientific and medical) band, which is universal in the world. The data rate is 1 Mbps. Time division duplex transmission scheme is adopted to realize full duplex transmission.
So the bar code scanner with Bluetooth technology has greater portability and compactness.
