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: A sectional type card feeding mechanism and method. The mechanism includes: a rear section mechanism including a rear section frame and a rear section belt, the rear section belt being movably connected to the rear section frame in a lengthwise direction of the rear section frame to convey cards; and a front section mechanism including a front section frame which is connected to an end of the rear section frame, the rear section belt driving the cards to be transferred to the front section frame to be discharged. The process of card feeding is divided into two sections. Cards are placed on the rear section belt of the rear section mechanism, and after the rear section belt conveys the cards to one end of the front section frame, the cards are sent to the other end of the front section frame to be discharged.
