【摘要】：近年我国各地的基础设施建设飞速发展，起重机械在社会工程建设中扮演着越来越重要的角色。起重机械是建筑工程中重要的施工机械，也是极易发生重大安全事故的特种作业机械，其自身结构蕴含的危险因素较多。随着起重机的工作日趋繁重，起重机事故发生率也越来越高，对人们的生命财产安全构成了很大威胁。因此，对起重机进行有效的健康监测将具有重大意义。为此，本文针对起重机的健康监测提出一种新型的、成本较低的、基于电阻应变片和RS-485总线的、多点式健康监测系统，此系统的成功研制将大大有助于结构健康监测思想及技术走进实际的工程机械监测应用。 本文提出一种新型电阻应变片封装方式，设计出一种适用于健康监测系统的专用电阻应变片，提出在起重机上基于电阻应变片和RS-485总线进行实时、多点式监测的方法，并在此基础上设计开发一套新型起重机健康监测系统。此起重机健康监测系统采用所研发的专用电阻应变片作为传感器，各监测点传感器采集到的监测信息通过RS-485总线传送给无线终端，再由无线终端通过GPRS网络发送至无线服务器，然后可由多个安装了该系统分析软件的起重机监测客户端通过Internet访问无线服务器的方式来读取监测信息，可实现多个客户端同时对起重机实时监测，进而实现起重机健康状况的多级监测管理。经科技查新，本课题是首次提出基于RS-485总线的多点式起重机健康监测系统开发，，也是首次将其成功应用在起重机的健康监测领域。 本文对所提出的起重机健康监测系统进行理论分析、硬件电路设计与开发、分析软件设计与开发、实验室内实验验证、不同健康监测系统的性能对比分析，实验结果证明该监测系统性能较为理想，随后将系统成功应用在了中国长航船舶重工金陵造船厂内的一台15吨桥式起重机和一台300吨门式起重机的健康监测，现场应用效果良好。
[Abstract]:In recent years, with the rapid development of infrastructure construction in China, lifting machinery plays an increasingly important role in the construction of social engineering. Lifting machinery is one of the most important construction machinery in construction engineering. It is also a kind of special working machinery which is prone to serious safety accidents. Its structure contains many dangerous factors. With the increasingly heavy work of cranes, the incidence of crane accidents is increasing, which poses a great threat to the safety of people's lives and property. Therefore, effective health monitoring of cranes will be of great significance. Therefore, this paper presents a new, low-cost, multi-point health monitoring system based on resistive strain gauge and RS-485 bus for crane health monitoring. The successful development of this system will greatly contribute to the application of structural health monitoring ideas and techniques to practical engineering machinery monitoring. In this paper, a new type of resistive strain gauge packaging method is proposed, and a special resistance strain gauge suitable for health monitoring system is designed. The method of real-time and multi-point monitoring based on resistive strain gauge and RS-485 bus on crane is put forward. On this basis, a new crane health monitoring system is designed and developed. The crane health monitoring system uses the developed special resistance strain gauge as the sensor, and the monitoring information collected by the sensors at each monitoring point is transmitted to the wireless terminal through the RS-485 bus. Then the wireless terminal is sent to the wireless server through the GPRS network, and then the monitoring information can be read by a plurality of crane monitoring clients which have installed the system analysis software and access the wireless server through the Internet. Multiple clients can monitor the crane in real time at the same time, and then realize the multi-level monitoring and management of crane health. After scientific and technological innovation, this subject is the first time to put forward the development of multi-point crane health monitoring system based on RS-485 bus, and it is also the first time to successfully apply it in the field of crane health monitoring. In this paper, the proposed crane health monitoring system theory analysis, hardware circuit design and development, analysis software design and development, laboratory experimental verification, performance comparison and analysis of different health monitoring systems, The experimental results show that the performance of the monitoring system is satisfactory, and the system has been successfully applied to the health monitoring of a 15-ton bridge crane and a 300-ton gantry crane in Jinling Shipyard of China long distance Shipping Company. The effect of field application is good.
