Problems solved by technology

[0010] However, as mentioned above, when applied to an energy-saving elevator in which an electric storage device such as a secondary battery is used in the elevator control device, a lot of power is required in order to control the added electric storage device
Usually, for example, the power required during a power outage is only sufficient to supply necessary equipment such as lighting, and for example, the power required for an elevator to be on standby is sufficient only to answer calls from the lobby, so there is at least a portion of the power required by the additional power storage device that is wasted. The problem

Embodiment approach 1

[0026] figure 1 It is a block diagram showing the configuration of the elevator control device according to Embodiment 1 of the present invention, and is an example of the system configuration for fully automatic operation of the elevator even during a power failure. The control board for controlling the elevator has a converter 2 composed of diodes and the like that converts the AC power output by the commercial frequency power supply 1 for the three-phase AC power into DC power, and the capacitor and the regenerative resistor 6 that pass through the DC bus 3 and The regenerative resistance control circuit 7 composed of transistors supplies the inverter 4 that converts the direct current converted by the converter 2 into alternating current with variable voltage and frequency, and the alternating current from the inverter 4 is supplied to the motor that drives the winch 6 in rotation. By rotationally driving the hoist 5, the car 8 and the balance weight 9 connected to both en...

Embodiment approach 2

[0038] In an energy-saving elevator that uses a power storage device such as a secondary battery as an elevator control device, a large amount of power is required to control the added power storage device. Usually, the electric power required for the elevator to stand by is sufficient only to answer calls from the hall, and therefore there is a problem that at least a share of the electric power required by the added power storage device is wasted. This second embodiment establishes a system that can suppress wasteful power consumption even if a power storage device is added to the control board.

[0039] image 3 It is a block diagram showing the configuration of the elevator control device according to Embodiment 2 of the present invention. image 3 In the shown embodiment 2, with figure 1 Parts of the system according to Embodiment 1 shown are denoted by system symbols, and description thereof will be omitted. image 3 In the shown embodiment 2, with respect to embodime...

Embodiment approach 3

[0047] Figure 7 It is a block diagram showing the configuration of an elevator control device according to Embodiment 3 of the present invention. Figure 7 In the illustrated embodiment 3, with image 3 The shown embodiment 2 is the same, the elevator control device 10 in the control panel is provided with a standby state identification device 10A, and at the same time, the charge and discharge control power supply device of the charge and discharge control device 16 of the power storage device 13 is connected with the elevator control device at the control panel side. The power supply unit 11 is shared.

[0048] This constitutes a common control power supply device, which can save space for the equipment. Therefore, the charge and discharge control power regulator 26 is provided so that the power supplied to the charge and discharge control device 16 can be controlled. This charge and discharge control power regulator 26 releases, for example, the contact 26a according to...

Abstract

PROBLEM TO BE SOLVED: To provide a controller of an elevator, allowing the construction of a system which suppresses the wasteful consumption of power of a power storage device in power failure or standby condition.

Description

technical field [0001] The invention relates to an energy-saving elevator control device using an electric storage device. Background technique [0002] The conventional elevator control device has a converter that converts the AC output from the three-phase AC power frequency power supply into DC power, and an inverter that converts the DC power converted by the converter into AC power with variable voltage and frequency. The alternating current is supplied to the electric motor that rotates and drives the hoist, and the hoist is driven by rotation, so that the car and the balance weight connected to the two ends of the cable wound on the hoist are raised and lowered. [0003] Here, the balance weight is set as the weight of the car to balance when passengers are on board. Therefore, in general, when the car is raised and lowered without load, traction operation is performed while the car is descending while consuming power, and regenerative operation is performed to resto...
