Abstract

The invention relates to an automatic arm rest lift or foot path control method and relative system, wherein said system comprises driver, arm rest lift controller, speed controller connected to the driver and arm rest lift controller to control the speed of driver, and load detector. The load detector inputs the detected the load signal of lift to the arm rest lift controller. And the control method comprises that: using detector to real-time detect the lift load; inputting detected load signal to the lift controller; the arm rest lift controller via speed controller controls the driver, to select relative operation speed; since the invention uses load feedback, via the flux to control the speed and save energy.

Description

Technical field

[0001] The invention relates to an escalator, in particular to an escalator or sidewalk control method and system. Background technique

[0002] Escalators and sidewalks are widely used in modern buildings. In places with high traffic such as shopping malls, supermarkets, stations, and airports, escalators or sidewalks are convenient and fast to use. When people step on, the escalator or sidewalk automatically Transport people to the upper floor or the next floor.

[0003] Existing escalators or sidewalks are driven by driving devices. Most of the escalators or sidewalks run at a fixed speed, that is, regardless of whether there are people on the escalator or the flow of people, they all run at the same speed. This will bring about the following shortcomings:

[0004] 1. When the flow of people is low, the escalator or sidewalk is always in operation, causing energy waste;

[0005] 2. When the flow of people is large, the running speed of the escalator or sidewalk...

Examples

Embodiment Construction

[0037] As shown in Figures 1 to 2, an escalator control system includes a drive device 5 that drives the escalator, an escalator control device 1, and a load monitoring device 4 and a speed control device 2. The speed control device 2 and the drive device 5 are at the same time , The controller 6 in the escalator control device 1 is connected and can control the speed of the drive device 5; the load monitoring device 4 monitors the load of the escalator, and transmits the monitored escalator load signal through wireless transmission (also through wired transmission Method) input to the escalator control device 1, and control the driving speed of the escalator drive device 5 according to the monitored load signal, forming a closed-loop control of the escalator load, with higher control accuracy, and several load intervals can be set in different load intervals Use the corresponding drive speeds respectively.

[0038]The load monitoring device 4 monitors the escalator load by detect...
