Abstract: An energy Internet system, an energy routing conversion device, and an energy control method, relating to a field of energy information. An alternating-current (AC) side energy routing conversion device of the energy Internet system includes a plurality of first route ports, and a direct-current (DC) side energy routing conversion device includes a plurality of second route ports, where each second route port is connected to a corresponding first route port by means of a corresponding DC busbar. A plurality of energy devices are connected to a DC busbar by means of corresponding first AC/DC converters or first DC converters. The AC side energy routing conversion device and the DC side energy routing conversion device collect energy information of the energy devices and adjust energy of the energy devices on a basis of energy balance constraint conditions.

Abstract: The present disclosure relates to the field of electronic card books, and more particularly, to a method for generating and using an electronic card book, the method may include: at a first step, purchasing a physical card book, at a second step, downloading APP, at a third step, verifying the physical card book, at a fourth step, generating an electronic card book, at a fifth step, generating an electronic card, at a sixth step, searching for electronic cards, and generating the electronic card book by downloading the APP, wherein the electronic card book corresponds to the physical card book, and the same electronic card book as the physical card book can be generated directly by scanning the QR code, the appearance and card format of the electronic card book are consistent with the physical card book.

Abstract: A plastic film includes an outer layer, a middle layer, and an inner layer. Each of the outer, middle, and inner layers includes a polyolefin elastomer. The polyolefin elastomer has better fluidity and can improve the dispersion effect of the polypropylene base raw material. The polypropylene base raw materials are mixed evenly and enhance the connection strength of the outer, middle, and inner layers of the plastic film. Each of the outer, middle, and inner layers includes a polyphthalamide resin, which can make the component more compact, more effective to enhance the tensile force. The plastic film has strong pulling force and is not easily damaged.

Abstract: A plastic film layer includes polyolefin elastomers. The polyolefin elastomers have better fluidity and can improve the dispersion effect of polypropylene base raw materials. The polypropylene base raw materials are mixed evenly, and enhance the bonding strength between plastic film layers. The plastic film layer also includes a polyaniline resin. A plastic film having the plastic film layer is also provided. The plastic film layer and the plastic film applying the plastic film layer have strong tensile force and are not easily damaged.
