【摘要】：随着计算机技术、电子技术、传感器技术的飞速发展,“黑匣子”技术不单单限于飞机,已逐步在塔式起重机(简称塔机)上得到应用,通过对塔机运行参数进行实时、准确地检测、记录和显示,一方面有利于操作员及时掌握塔机运行状况,避免事故发生；另一方面有利于管理员或分析员对塔机运行状态进行回放分析。本文以塔机为研究对象,采用LabVIEW开发环境和数据采集卡设计了塔机运行参数实时记录与分析系统。 首先,通过对塔机结构及其工作特点进行介绍与分析,确定了影响塔机安全的主要运行参数。其次,针对不同的运行参数设计了不同的检测方案,在起重量检测方面,选定轴销式称重传感器对起重量进行获取,针对塔机称重范围广、采集卡A/D存在单位转换误差等设计了信号分段调理电路,针对传感器输出信号被分段放大和传输中存在衰减等设计了信号还原及线性补偿算法,实现了起重量的高精度转换,并完成了超载检测和数据实时存储；在起升高度、小车幅度、回转角度及运行速度检测方面,针对塔机三大机构的工作及结构特点,选定光电编码器对运行速度等参数进行获取,通过对光电编码器测角度及测速算法研究,结合DAQmx编程模块,实现了各参数的实时检测、超限报警和数据存储；在起重力矩检测方面,通过分析改进后的弓形板力矩限制器工作原理,在函数型连接神经网络基础上引进BFGS及补偿算法,实现了起重力矩的高精度测量。最后,基于LabVIEW开发环境,对塔机运行参数进行实时检测,并根据记录的数据,结合实际应用,构建了集系统登录、时间选定、参数选择、数据分析和文本打印等于一体的塔机运行参数分析系统,实现了塔机运行状态回放,便于管理员或分析员进行事故评定和工作汇报。 实验结果表明,塔机运行参数实时记录与分析系统检测精度高、功能强、实时性、稳定性及实用性好、人机交互界面友好。
[Abstract]:With the rapid development of computer technology, electronic technology and sensor technology, "black box" technology is not limited to aircraft, but has been gradually applied in tower crane (abbreviated as tower crane). Through real-time, accurate detection, recording and display of tower crane operation parameters, on the one hand, it is helpful for operators to master the operation condition of tower crane in time and avoid accidents. On the other hand, it is helpful for the administrator or analyst to play back and analyze the running state of the tower crane. In this paper, the real-time recording and analysis system of tower crane operation parameters is designed by using LabVIEW development environment and data acquisition card. Firstly, through the introduction and analysis of the structure and working characteristics of the tower crane, the main operating parameters that affect the safety of the tower crane are determined. Secondly, different detection schemes are designed for different operation parameters. In the aspect of lifting detection, the pin weighing sensor is selected to obtain the lifting weight, the signal segmented conditioning circuit is designed for the wide weighing range of tower crane and the unit conversion error of acquisition card A 鈮，
