Six identification way through multiple anti-counterfeiting, can identify clamp, others, even zhang, zhang worn coin - missing Angle, half zhang, sticker, scribble, oil and other abnormal state of the notes, and combined intelligent banknote counter which is a summary would rise to the full.
1. Magnetic signature: detect the distribution of magnetic ink of paper money, and also detect the fifth version of RMB security line;
2. Fluorescence detection: check the quality of the paper money with ultraviolet light, and monitor it with the photoelectric sensor. If there are small paper changes, it can be imitated;
3. Penetration authentication: according to the characteristics of the RMB, the ability to identify various counterfeit COINS is increased by using the model of penetration authentication.
4. Infrared authentication: using advanced fuzzy recognition technology, it can effectively identify various counterfeit COINS according to the infrared characteristics of banknotes;
5, multispectral counterfeit detection: in different wavelength of LED particles arranged in the matrix of multispectral light source, lens array, cell array image sensor, control and signal amplifying circuit and input/output interface; Multispectral light source and lens array form optical path system, used for emitting light and reflected light focused on the renminbi to the image sensor cell array, using the multi-spectral image sensor image analysis function, identification was carried out on the money.
6. Quantitative qualitative analysis and detection: using high-speed parallel AD conversion circuit, high-fidelity acquisition signal, quantitative analysis of ultraviolet light, and detection of counterfeit money with weak fluorescence reaction; Quantitative analysis of the magnetic ink of RMB; Fixed point analysis of infrared ink; The fuzzy mathematics theory is used to quantitatively quantify some factors which are not clear and easy to quantify, and a multi-level evaluation model of security performance evaluation is established.
