Portable Barcode Scanner barcode scanning module parts barcode scanning module portable bar code scanning module, I believe many people are not very familiar with it! Beginning when the first contact does not understand what it is, what the industry is generally used in it! Barcode scanning module is not the same as with an ordinary scanner it! According to various constant contact, and they knew the scan module is actually one of the key parts sweep decoder inside, which help to sweep the yard's operation process. Also have full independence barcode scanning and decoding functions, and applications can be written in various industries program according to demand, it has a small, highly integrated, you can easily be embedded into mobile phones, tablets computers, printers, assembly line equipment, medical equipment , and other industries device. By scanning the bar code scanning module similar module can be divided into one-dimensional and two-dimensional code code modules, according to sources with the red laser modules can be divided into modules. Red laser modules and laser scanning module module principle difference between the internal laser device by a laser light source point play, playing with a reflective film on the mechanical structure of the device, and then rely on the vibration motor swings a laser point into a laser line labeled according to the bar code, and then decoded into a digital signal through the AD. Red scanning module commonly used LED light emitting diode light source, by CCD sensor, and then through the photoelectric signal conversion. Most rely on laser scanning module to fix the machine dispensing cause mechanical device, so it tends to be easily damaged when swinging pendulum piece off, so we can often see the number of laser scanning gun dropped out of the light source has become a point , resulting in a very high repair. Red scanning module with no mechanical structure, laser anti-throw immeasurably, so stability is better, red scanning module failure rates far below the laser scanning module. Red laser and physical principles of view: refers to the energy of laser stimulated emission intensity, parallelism good light, but is now mostly red LED light, red light is not what we say that infrared, physics definition Infrared is the temperature of the object radiating an electromagnetic wave of spontaneous, not visible. Infrared includes all wavelengths longer than red light, while the laser means that certain wavelengths of light, they two are not necessarily linked, does not belong to the same field. Laser light is amplified by stimulated emission of radiation generated by the infrared eye that can not be observed in the frequency spectrum of the larger part of the smaller wavelength, from the 0.76 to 400 microns, the wavelength and energy from their decision in light Under the red light penetration and poor immunity than the laser, so that the laser outdoors in bright light than red light is good.
