Problems solved by technology

However, this technology cannot be directly used in elevators. The reason is that the safe operation of elevators is the most important factor that must be considered in energy-saving work, and energy-saving and power-saving technologies in other fields cannot guarantee the safe operation of elevators.

Embodiment 1

[0025] An elevator intelligent power-saving method according to the present invention, the method includes: according to the set disconnection working time, intelligent judgment and control technology, and by detecting the change of the elevator main circuit current or main circuit power, it is determined whether the elevator is in Standby state: After the elevator is in the standby state for a certain period of time, the actuator is triggered to cut off the current of the main circuit of the elevator, realizing the function of intelligently cutting off the power supply when the elevator is in the standby state. The above-mentioned intelligent judgment and control technology is to compare the detected value and the threshold value in the detection cycle according to the set threshold value when the elevator’s disconnection working time is reached, and automatically Determine whether the elevator is in a standby state, and output a signal to drive the actuator.

Embodiment 2

[0040] Such as figure 2 and image 3 As shown, this embodiment provides an elevator intelligent power-saving device and the working principle of the device. The elevator intelligent power-saving device is installed between the elevator main switch and the control cabinet. The device includes a main detection module 1 , an intelligent judgment and control module 2 , an actuator module 3 and a human-computer interaction module 4 , wherein the main detection module 1 is composed of three front-end sensing heads 5 . The front-end sensing head 5 adopts a current transformer and is connected in series to the three-phase circuit to detect the current of the three-phase circuit 8 of the elevator. The main detection module converts the detected current signal into a voltage signal and feeds it back to the subsequent intelligent judgment And the decision module 9 in the control module 2. The position where the front sensor head 5 is connected in series is before the actuator module 3...

Abstract

The invention discloses an intelligent power-saving method and an intelligent power-saving device for a lift. The intelligent power-saving method for the lift comprises the following steps: according to the set turn-off time, judging whether the lift is in a standby state based on the intelligent judgment and control technology by detecting the change of current of a main circuit of the lift; and triggering an executing mechanism to switch off the current of the main circuit of the lift after certain time of the standby state of the lift is prolonged so as to realize the function of intelligently switching off a power supply when the lift is in the standby state. The intelligent power-saving device for the lift comprises a main detection module, an intelligent judgment and control module, an executing mechanism module and a man-machine interaction. The intelligent power-saving device for the lift has the characteristics of high degree of safety, simple implementation, obvious energy-saving effect, high reliability, intelligence, long service life and the like.

Description

technical field [0001] The invention relates to the design and application field of energy-saving and power-saving technology or equipment, in particular to an elevator intelligent power-saving method and device based on intelligent judgment and control technology.
