Elevator powered by composite power supply

Abstract

The invention discloses an elevator powered by a composited power supply, belonging to the field of elevators. The elevator comprises a commercial power supply, a power supply input identification interface, an intelligent power supply controller, a power supply output identification interface, an elevator driving controller, an elevation car, an energy-saving and environmental-friendly power supply and an energy storer; the energy-saving and environmental-friendly power supply is connected with the power supply input identification interface; the input end of the energy storer is respectively connected with the commercial power supply and the output end of a power supply driving controller; and the output end of the energy storer is connected with the input end of the power supply input identification interface. The elevator is powered by the energy-saving and environmental-friendly power supply in a normal state; when the energy-saving and environmental-friendly power supply can not supply enough quantity of electricity or is subjected to an fault, the elevator can adopt the energy storer charged by the commercial power supply as the stand-by power supply so as to run continuously; and the elevator is simple in structure, saves the use cost and the energy and achieves the purposes of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a composite power supply elevator in the field of elevators. Background technique [0002] Today's society has been advocating the use of green energy, and various fields are researching and promoting products powered by green energy. The electric moped is the most typical green energy product. It has successfully occupied a broad market with its low price and low cost of use. It not only facilitates people's travel, but also greatly reduces urban pollution. [0003] Elevators are used in high-rise buildings in the city. These elevators are basically powered by the mains power supply. In today's increasingly tense power source, whether it is possible to study a new type of energy elevator has become an urgent problem to be solved. The mains power supply elevator runs relatively stable when the power pressure is not high, but in some special cases, such as summer, when high-power electrical appliances are running in the city, t...

AI Technical Summary

Problems solved by technology

The mains power supply elevator runs relatively stable when the power pressure is not high, but in some special cases, such as summer, when high-power electrical appliances are running in the city, the voltage of the whole city becomes very unstable. As the elevators that people rely on in high-rise buildings, once there is a power failure, the trapped passengers have to wait for the electric personnel to repair, thus wasting time, delaying work and travel, and if the time is too long, there will be a series of problems Cascading problems, causing more losses
