Cableway protecting method, device and system

Abstract

The embodiment of the invention provides a cableway protecting method, device and system, and relates to the technical field of cableways. According to the method, device and system, a driving wheel angular displacement signal collected by a signal collecting module is obtained, operation status parameters of a cableway are determined according to the angular displacement signal, wherein the operation status parameters include the cableway operation distance, and finally, when the operation distance is equal to a first preset threshold, a high-speed instruction loop is removed so that a compartment can be decelerated; due to the fact that when the operation distance is equal to the first preset threshold, a high-speed instruction loop in an original cableway control system is directly removed, the compartment is decelerated and operated, and therefore the phenomenon that the cableway runs into a station can be avoided; meanwhile, under the condition that an original control system is kept, only the cableway protecting system is added, the safety level of an old cableway can be greatly improved, the cableway can have the safety protecting function and the convenient testing means like a new cableway, higher safety standards are met, and the service time of the old cableway is prolonged.

Description

technical field [0001] The invention relates to the technical field of cableways, in particular to a cableway protection method, device and system. Background technique [0002] Ropeway (Ropeway), also known as crane, cable car, flow cage, is a kind of means of transportation, usually carrying passengers or goods up and down the rugged hillside. The cableway is to use the steel cables suspended in mid-air to support and pull passenger cars or trucks. [0003] In the prior art, some cableways use one set of control systems, or two sets of redundant control systems, or two sets of hot standby control systems to ensure the low-speed entry of reciprocating cableways, ground cable cars and pulsating circulation cableways. These solutions all have the following problems: the first is that logic control and safety protection are completed in one control system; the second is that it is too wasteful, two or more sets of medium and large programmable controllers, or using Safety pr...

Problems solved by technology

These solutions all have the following problems: the first is that logic control and safety protection are completed in one control system; the second is that it is too wasteful, two or more sets of medium and large programmable logic controllers, or using Safety programmable controllers are expensive; the third is that the complexity of multiple sets of control cores increases the failure rate significantly; the fourth is that the design and debugging of multiple sets of control cores requires high requirements
