Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.
[0014] See attached figure 1 , this embodiment is composed of a printable coating 1 , a PET insulating base layer 2 , an adhesive layer 3 , and a backing paper 4 that are laminated in sequence. And it is equipped with a radio frequency reader 7 .
[0015] According to the coating principle, in order to prevent corrosion and erosion by water, turbid solvents and organic solvents, a spray liquid is sprayed on the PET insulating base layer 2 to form a printable coating layer 1 . The printable coating 1 can be printed, color patterns and prints, characters, numbers, serial numbers and the like.
[0016] See attached figure 2 According to the present invention, an electronic chip 6 and an invisible watermark fluorescent part 5 are embedded in the PET insulating base layer 2 with functions of encryption calculation and storage. The configured radio...

The invention discloses an anti-counterfeit technology of the verification certificate of an intelligent electric power metering device. The verification certificate comprises a printable coating layer, a PET insulating base layer, an adhesive layer and bottom paper which are sequentially adhered to one another. The printable coating layer is arranged on the PET insulating base layer, and an encryption-operation electronic chip and an invisible watermark fluorescent part are built in the PET insulating base layer. The verification certificate is provided with a radio frequency reader, and theradio frequency reader transmits a high-frequency signal to activate and read data and information input by the electronic chip. The ultraviolet lamp of the radio frequency reader lights the information of the invisible watermark fluorescent part to allow the information to be displayed on a display screen. The ultraviolet lamp in the radio frequency reader can light the pattern, text and digits of the invisible watermark fluorescent part. When the verification certificate is soaked in a volatile solvent, the printed information, text, pattern and colored digits of the verification certificatecannot be eroded, the built-in electronic chip of the insulating base layer can work normally, the pattern, text and digits of the invisible watermark fluorescent part are clear and bright under ultraviolet light, and the verification certificate is novel in design, low in cost, convenient to use, evident in effect, comprehensive in technological performance and disposable.
Description
technical field [0001] The invention relates to the anti-counterfeiting technology of the verification certificate of intelligent power measuring instruments, in particular to the technical performance and the anti-counterfeiting technology of the verification certificate of the smart electric meter and the transformer of the metering device. Background technique [0002] The 21st century is a century of scientific and technological progress, but also a century of scientific and technological regulations and the establishment of a sound legal system. Whether it is high-tech, precise, cutting-edge science and technology, or a small power measuring instrument certification, all have been fully demonstrated in the trend of great scientific progress. [0003] In the past, the verification certificates of electric measuring instruments were very arbitrary, without technical specifications, technical requirements, and lack of scientific and realistic, serious and serious attitude ...
