Embodiment Construction

[0044] In the elevator emergency power supply device provided by the present invention, the measurement and control circuit detects the power supply state of the current power supply grid, and when the power supply state is abnormal, the backup power supply line supplies power to the elevator group to ensure the normal operation of the elevator.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] A specific structure of an elevator emergency power supply device provided by the present invention is as...

Abstract

The invention relates to an emergency power supply device and an emergency power supply method for a lift. The emergency power supply device comprises a power supply input port connected with a power supply grid, a power supply output port connected with a lift group, a first power supply line, a battery, an inverter, a second power supply line and a measurement and control circuit, wherein the first power supply line is arranged between the power supply input port and the power supply output port and provided with a first switch; the second power supply line is arranged between the inverter and the power supply output port, used for transmitting three-phase alternating voltage output by the inverter in a sine wave mode and provided with a second switch; and the measurement and control circuit is connected with the power supply input port, the first switch, the inverter and a control circuit of the second switch, and is used for determining the power supply state of the power supply grid by detecting the power supply condition of the power supply input port and switching the first power supply line and the second power supply line by controlling turn-on and turn-off of the first switch and the second switch according to the power supply state. By the emergency power supply device and an emergency power supply method, the lift can normally run through power supply of a spare power supply line when the power supply state of the power supply grid is abnormal.

Description

technical field [0001] The present invention relates to the technical field of elevators, and more specifically relates to an elevator emergency power supply device and method. Background technique [0002] As a widely and frequently used transportation equipment in contemporary society, elevators must first ensure safety, and secondly, ensure speed and comfort. [0003] In general, the elevator is powered by the power grid to work. When the power grid is abnormal, the elevator will stop working, and the running elevator will stop immediately and perform mechanical brakes. Passengers in the elevator will be trapped in the elevator again. In this case, if passengers use incorrect means (such as breaking the door), danger is likely to occur. If the elevator shutdown occurs in a hospital, it is easy to delay the treatment of the patient due to the patient or doctor being trapped in the elevator. Danger on the spot due to nervousness. Contents of the invention [0004] In vi...
