Escalator or foot path control method and system

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...

AI Technical Summary

Problems solved by technology

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

[0005] 2. When there is a large flow of people, the running speed of the escalator or sidewalk is fixed, which cannot effectively guide the flow of people, resulting in blockage of the flow of people

For example, the Chinese patent titled "Escalator Frequency Conversion Control Device" and the application number 97226731. The operating speed of the escalator is to switch between the zero-speed operating state, low-speed operating state, and high-speed operating state; this structure fails to effectively solve the following problems:

[0008] 1. The escalator or sidewalk can only detect two states of people or no one, and no specific flow signal of people is input to the control device; that is, the escalator only detects two states of people and no one, and the detected information is very inaccurate;

[0009] 2. The detection of the flow of people on the escalator or sidewalk is not a dynamic and real-time data, so the escalator cannot really control the running speed of the elevator according to the flow of people;

[0010] 3. The detected information is very inaccurate, which leads to the unsatisfactory energy-saving effect of the escalator
