【摘要】：电梯是一个时变系统,电梯在运行过程中的状态受到乘坐人数和运行高度的影响。电梯在运行过程中产生的机械振动,会对电梯系统产生附加的动载荷,影响电梯系统的正常工作,并且振动及其产生的噪音会影响乘客的舒适感和健康。所以,对电梯轿厢在运行中的振动和噪音进行监测,是目前电梯行业的一项很重要的技术。本学位论文结合与巨人通力电梯有限公司合作的项目“电梯乘运质量分析专家系统”,主要从以下几个方面进行了研究。第一章,阐述本论文的研究背景和意义。重点介绍国内外对电梯远程监测系统的研究现状,以及现有电梯远程监测系统的优缺点,并提出本论文的研究内容和论文框架。第二章,建立了垂直和水平方向的动力学模型,使用MATLAB编程,对电梯垂直振动和水平振动进行模态分析,并得出一些有用结论,为振动信号的分析提供理论依据。第三章,对电梯乘运质量远程监测系统的硬件进行开发设计,包括轿厢数据采集器和远程数据传输器。轿厢数据采集器以TMS320VC5509A为核心,远程数据传输器以MSP430F149为核心。最后,完成了轿厢数据采集器和远程数据传输器的实物硬件电路板的设计制作。第四章,完成了电梯乘运质量远程监测系统程序的开发设计,包括轿厢数据采集器、远程数据传输器固件和远程服务中心软件的设计开发,程序以模块化方式进行设计。第五章,对开发的电梯乘运质量远程监测系统进行了实验研究。实验包括加速度信号采集实验、噪音信号采集实验和无线传输实验。第六章,对前述工作进行总结,并对今后工作方向进行展望。
[Abstract]:Elevator is a time - varying system , the state of the elevator during operation is influenced by the number of passengers and the height of operation . The vibration and noise generated by the elevator during operation can affect the comfort and health of the elevator system . Therefore , it is an important technology in the elevator industry . In the first chapter , the research background and significance of this paper are described . The present situation of the remote monitoring system of the elevator and the advantages and disadvantages of the existing remote monitoring system are introduced , and the research contents and the paper frame of this paper are put forward . In chapter 2 , the dynamic model of vertical and horizontal directions is established , and the modal analysis of vertical vibration and horizontal vibration of the elevator is carried out by using MATLAB , and some useful conclusions are obtained .
