Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] The work of the present invention is completed through several links such as uplink and downlink signal acquisition, speed signal acquisition, brake control, speed regulation and energy-saving operation, brake monitoring (selection), ladder speed monitoring (selection), and several links; the specific working principle is as follows:

[0016] Up and down running (Fig. 1): The operator starts the escalator according to the regulations, and the original control device of the escalator automatically detects that each safety switch is qualified and then provides three-phase alternating current A, B, C to the wiring terminals of the escalator motor in the circuit of the present invention, Connect with the incoming line terminals R / L1, S / L2, T / L3 of the inverter as the inverter power supply. On the other hand, it is connected to the upstream relay SXJ, the d...

Abstract

The invention relates to an automatic arm rest lift energy saving method, with the energy saving device inspection automatic arm rest control circuit sending three phases power supply phase change to decide the positive and negative running direction of the lift through converter controlling the running of the lift. Energy saving device is used to inspect the circuit for lift loading, sending out a low speed running signal through converter while the lift is free from load. While unchanging the original control, it has small linking lines, free from the up, down and running signals of the sampling original control circuit.

Description

technical field [0001] The invention belongs to an elevator control device, in particular to an escalator energy-saving control method and device. Background technique [0002] At present, most of the escalators used in the market adopt the form of AC drive, and the electric control cabinet directly controls the positive and negative rotation of the escalator motor, so that the escalator can complete the up and down operation, so there is a large starting current (which is the rated current of the escalator motor) 3 times of the escalator); regardless of whether there is a load on the escalator, the escalator motor is in a high-speed running state for a long time, which consumes energy and other defects. Contents of the invention [0003] The purpose of the present invention is to provide a kind of control circuit of the original escalator, which can not only control the dragging of the universal frequency converter through the current vector type, improve the power factor...
