Friends who have been to the supermarket should have seen such a scenario, when the cashier needs to scan the bar code of items near the bar code scanner gun sensor area, we will hear a "tick" sound, the product bar code has been successfully read. This is because the scanner gun is opened to the automatic induction of the scanning mode, most of the bar code scanner guns have auto sensing scanning function, according to the actual scanning needs fingers in the on or off state. What exactly is this function of the bar code scanner?
1.Aoto sensing mode
A. Aoto sensing mode is an operating mode that is activated only when the scanner detects a bar code approaching. It does this by means of a built-in sensor. When the sensor detects a bar code, the light source is automatically activated for the scanning operation.
B. One of the advantages of the auto sensing mode is that it significantly reduces energy consumption and extends battery life. Because the light source is activated only when needed, no energy is wasted. In addition, the auto sensing mode avoids the irritation to the human eye caused by a continuously projected light beam, making operation more comfortable and safer.
C. Application scenarios for the auto sensing mode include work environments that require frequent use of the scanning function but not continuous scanning. For example, a shop cashier often needs to scan product barcodes, but not continuously. Auto sensing mode is also suitable for users who wish to conserve energy and extend battery life.
D. However, there are some limitations and caveats associated with the self-sensing mode. Since it is necessary to wait for the scanner to detect a bar code before activating it, the response time may be slightly extended. In addition, for tasks that require continuous and rapid scanning, the auto sensing mode may not be adequate.
2.Continuous Mode
A. Continuous Mode is another common barcode scanner operating mode. In always mode, the light source is always on and ready to scan. There is no need for a second trigger, the scanner will read the barcode data immediately.
B. One of the advantages of continuous Mode is that it is suitable for tasks that require continuous and rapid scanning. In industries such as warehousing and logistics, where high-speed, continuous scanning is required, the continuous mode can provide fast and stable scanning performance.
C. Application scenarios for continuous Mode include industries that require high-speed continuous scanning and tasks that require immediate data collection and feedback. For example, fast moving distribution centres need to scan large quantities of goods quickly for efficient and accurate distribution.
D. However, there are some limitations and caveats to continuous Mode. Firstly, the continuous mode consumes more power and can result in shorter battery life. In addition, the continuously emitted light beam can cause glare and eye strain problems, requiring attention and caution during use.
Auto sensing scanning mode with always continuous scanning mode in essence is different, ordinary laser scanner gun need a hand to hold the items, a hand to take the barcode scanner for scanning, two hands are occupied, some items are larger or heavier, so a hand to take the items more trouble, auto sensing scanner gun on the liberation of a hand. Laser barcode scanner as an optical electronic device, it is still relatively fragile inside the photoelectric element, auto sensing scanning, do not have to touch the scanning gun, the scanning gun is placed in the bracket, in a more fixed state, so that the scanning gun life will be longer, the key will not be bad, the data line will not often be pulled.
