Problems solved by technology
[0004] For this reason, the present invention provides a detection method of a waterproof invisible barcode based on an electrical detection method, which can effectively solve the problem that in the prior art, the correctness of the barcode cannot be judged by the wavelength, and then the electrical signal strength can be used to determine whether the barcode can be repaired. Technical issues of low detection correctness and low integrity of output barcode information

The invention relates to a detection method of a waterproof invisible barcode based on an electrical detection method, comprising: step S1, using a barcode scanner to scan and detect the barcode; step S2, comparing the actual wavelength L with a preset wavelength to determine the corresponding information of the barcode Whether it is correct; step S3, compare the wavelength difference △L with the standard wavelength difference △L0 to determine whether the barcode needs to be repaired; step S4, compare the barcode electrical signal strength P with the barcode electrical signal standard strength to determine whether the barcode can Repair; step S5, compare the barcode electrical signal strength difference ΔP with the barcode electrical signal standard strength difference to determine the barcode repair coefficient, and the repair unit repairs the bar code that can be repaired according to the determined bar code repair coefficient; step S6, The output unit outputs barcode information. Therefore, the correctness of barcode detection and the integrity of output barcode information can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of barcodes, in particular to a detection method of a waterproof invisible barcode based on an electrical detection method. Background technique [0002] Barcode is a common anti-counterfeiting mark in life. It forms a graphic identifier through different widths and blanks of barcodes and different reflectivity according to certain coding rules. It can carry a lot of information, such as production location, production date, Mail starting and ending points, product information and book classification, etc. Therefore, it has a wide range of application scenarios, especially in security information, product identification. In recent years, it has also been widely used in the logistics industry. Encoding various information through barcodes can save a lot of manpower and time. In addition, the current barcodes are based on the principle of optical detection. The barcode scanner emits light that hits the barc...
