Online analysis meter and online analytical method for operation performance of elevator

Abstract

The invention relates to an online analysis meter and an online analytical method for operation performance of an elevator, belonging to the elevator technology field, the online analysis meter and the online analytical method are characterized in that: an upper computer is used for realizing the statistics and analysis of a signal, an embedded industrial controller serves as a main controller, on-site operation is performed by a touch screen, a lower computer is used for realizing the acquisition and processing of the signal and comprises a signal processing module, a signal collecting module, an A/D (Analog-to-Digital) conversion module, a three-axis acceleration sensor and a sound sensor, and the signal processing module is a main controller. By the analysis meter and the analytical method, the online analysis is performed to the operation performance of the elevator, the failure prediction and early warning of the elevator are realized based on an elevator three-axis acceleration and noise signals, a reliable quantified index is provided to analyze and evaluate the safety of the elevator, an effective technical method is provided for the operation quality measurement and risk assessment for the elevator, the online analysis meter adopts a dual-processor structure, thereby ensuring the acquisition and preprocessing of the signal in a high-speed and high-precision manner and having the mass storage capacity and flexible statistic analysis function.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator running performance online analyzer and an online analysis method. Background technique [0002] Elevators are an indispensable means of vertical transportation in cities. With the development of economy and society, the number of elevator equipment is increasing day by day. At present, the number of elevators in use in my country has exceeded 1.5 million units, becoming the world's largest elevator manufacturing base and elevator market. The number of elevator equipment in big cities is increasing year by year at a rate of 20%. However, due to the frequent operation of elevators, the maintenance units are mixed, and the elevators are "aging" year by year, and they have entered a period of frequent failures. [0003] In order to ensure the safe use of elevators, my country has formulated strict supervision and management regulations, which put forward sp...
