Embodiment 1

[0034] see figure 1 The schematic diagram of the overall structure of the first embodiment of the elevator car power supply device of the present invention is shown, the elevator car power supply device mainly includes a power generation unit and a power processing unit, the power generation unit further includes a drive device and a power generation device, and the power processing unit The unit further includes a power processing circuit and a power processing controller, the power processing circuit is composed of a first power conversion device, an energy storage device and a second power conversion device, and the power processing controller is controlled by the first power conversion controller and the second power conversion device composition.

[0035]When the elevator car moves up and down, the driving device converts the up and down movement of the elevator car into a motion capable of driving the power generation device, and drives the power generation device to gen...

Embodiment 2

[0048] image 3 Shown is the overall structure schematic diagram of the second embodiment of the elevator car power supply device of the present invention. This embodiment is similar to the first embodiment, and only the differences from the first embodiment will be described below. In addition to including a power processing circuit, a power processing controller and a state detection device, the power processing unit also includes a communication device for communication between the elevator car power supply device and the elevator main controller. The communication device passes a signal The wire is connected with the electric energy processing controller, and the communication with the main controller of the elevator has been realized in a wireless manner.

[0049] The first power conversion controller also adopts figure 2 The voltage and current double-closed-loop structure shown is only one input of its voltage control unit——the energy storage status command value V o...

Abstract

The invention discloses an elevator car power supply device which comprises an electricity generation unit and an electric energy processing unit, wherein the electricity generation unit is fixed on an elevator car and uses lifting motion of the car to generate electricity, and the electric energy processing unit is fixed on the elevator car, processes the electric energy output by the electricity generation unit and provides the electric energy to power devices of the elevator car. The electricity generation unit uses the lifting motion of the car to generate electricity, and the generated electricity is provided for the power devices of the elevator car after being processed by the electric energy processing unit. The elevator car power supply device does not need to guarantee a distance between a power supply line and a powered device and is low in installation complex degree and accuracy requirements, quantity of device components and cost are not increased along increase of height of buildings or quantity of layer stations, the car can be powered while the car does the lifting motion, and regeneration energy of an elevator motor is used for supplying electricity to accordingly achieve energy saving of an elevator. The invention further discloses a control method of the elevator car power supply device.

Description

technical field [0001] The invention relates to a power supply device for an elevator car, in particular to a device for supplying power to an elevator car in a non-cable manner. The invention also relates to a control method of the elevator car power supply device. Background technique [0002] The elevator car contains electrical equipment such as lighting devices, fans, control boxes, door operators, etc., all of which need a power supply to provide them with electrical energy. In the past, the electric energy of these devices all is to supply power to the car by the elevator power supply through the power supply cable that goes up and down together with the car. However, with the continuous increase of the hoisting height of the elevator, the required power supply cable length is also continuously increased. Generally speaking, buildings will shake to a certain extent due to wind blowing and other reasons, especially high-rise and super high-rise buildings. Since the ...
