Considerations for purchasing barcode scanners

<

Considerations for purchasing barcode scanners Barcode scanners are widely used in various industries, such as medical care, logistics, etc., as well as the most popular WeChat two-dimensional code technology. What parameters should the bar code scanners pay attention to when purchasing?

1, the resolution, refers to the correct detection of the width of the narrowest symbol read. In the purchase, the resolution is not as good as possible, and the resolution should be selected according to the barcode density used. Otherwise, high resolution results in smear marks, de-inking, and other serious effects on the system. The resolution of the bar code scanner is determined from three aspects: the optical part, the hardware part and the software part.

2. Scan depth of field refers to the difference between the farthest distance that the scan head allows from the surface of the bar code and the closest point where the scanner can approach the surface of the bar code, that is, the effective working range of the code scanner. To distinguish it from the scanning distance, that is, the scanning head allows the shortest distance from the surface of the barcode, the two should not be confused.

3. Scanning width, the physical length of the barcode information that can be read by scanning the beam at a given scanning distance.

4. Scanning speed refers to the scanning frequency of the scanning beam on the scanning trajectory per unit time.

5. For the hand-held light pen scanning recognition method, one recognition rate needs to be considered, that is, the ratio of the number of labels read in the first scan to the total number of scanning labels. Due to various factors, it is basically impossible to achieve a recognition rate of 100% at one time, but people still hope to pass every scan.

6. Bit error rate, which is equal to the ratio of false identification times to total identification times, is an important indicator.

7. When selecting the full-angle scanner, attention should be paid to the spot distribution of the scan lines: multiple parallel lines in one direction, multiple scan lines at a certain point, and the probability of interpretation at each point within a certain spatial range. Convergence. If you do not meet the above distribution, it is best not to buy.
