Description
技术领域technical field
本发明涉及电梯测控技术领域,特别是涉及一种电梯故障检测预警系统及方法。The invention relates to the technical field of elevator measurement and control, in particular to an elevator fault detection and early warning system and method.
背景技术Background technique
随着经济的发展,人口的增长,现代城市中的高楼大厦已经越来越多,电梯也越来越在人们的生活工作中普及。随着电梯的不断增多,电梯故障的发生率逐年上升,因此电梯的运行安全也越来越得到人们的关注。为了保障电梯的安全运行,一方面要靠电梯本身的制造和安装质量,另一方面,最为重要的是要靠运行过程中及时高效的维修养护工作。维修保养除了周期性保养外,还有就是在电梯发生故障时要及时发现和排除。With the development of the economy and the growth of the population, there are more and more high-rise buildings in modern cities, and elevators are becoming more and more popular in people's lives and work. With the continuous increase of elevators, the incidence of elevator failures is increasing year by year, so the operation safety of elevators is getting more and more attention. In order to ensure the safe operation of the elevator, on the one hand, it depends on the manufacturing and installation quality of the elevator itself, and on the other hand, the most important thing is to rely on timely and efficient maintenance during operation. Maintenance In addition to periodic maintenance, there is also the need to find out and eliminate in time when the elevator breaks down.
面对数量巨大的电梯监管任务,传统的电梯监管在预警、预防、快速响应等方面存在不足,加上百姓对美好城市生活的向往,在此新形势下,对电梯故障预测方式进行探索,挖掘新的电梯故障预测方式十分必要。且由于电梯轿厢较重,在进行高低层运行时,可能会发生各种故障,导致电梯无法正常运转,甚至有伤害人们人生安全的风险,所以需要对电梯进行故障预警,以达到提前排障的目的,然而现有的故障预警方式多是依靠经验较为丰富的维修人员进行人工排障预警,这种预警方式造成效率低下,而且预警不够全面,容易造成安全隐患堆积。Faced with a huge number of elevator supervision tasks, the traditional elevator supervision has deficiencies in early warning, prevention, rapid response, etc., coupled with the people's yearning for a better city life, under this new situation, the elevator fault prediction method is explored and excavated. A new elevator failure prediction method is necessary. And because the elevator car is heavy, various failures may occur during high and low floor operation, resulting in the elevator not operating normally, and even the risk of harming people's life safety, so it is necessary to carry out fault warning on the elevator to achieve early troubleshooting However, most of the existing fault early warning methods rely on experienced maintenance personnel to perform manual troubleshooting and early warning. This early warning method results in low efficiency, and the early warning is not comprehensive enough, which is likely to cause accumulation of safety hazards.
因此,本发明提供了一种电梯故障检测预警系统及方法。Therefore, the present invention provides an elevator fault detection and early warning system and method.
