【摘要】：矿井提升机作为煤矿生产的重要组成部分,对其安全性的监测显得尤为重要。而随着机械制造技术精细化的发展模式,设备的常规监测也受到人们的关注。目前越来越成熟的监测手段无疑给提升机的数据监测提供了技术支持。本文深入分析提升机的基本组成结构、运行特点和常见故障形式,详细研究了几种重要参数的监测原理并比较他们的不同,以便选择适用的方法来进行测量计算。要建立一个完整的测量系统,需从硬件、软件、算法三方面入手。其中硬件是支撑,软件是核心,而算法便是衔接这两者很好的桥梁。首先硬件方面,主要包括传感器选型、驱动板与ATK-SIM900A模块集成以及与USR-LTE-7S4型4G无线终端匹配。在选型上应充分考虑提升机的特点,此外还需考虑环境因素对传感器的影响。对于USR-LTE-7S4型4G模块则重点在其与ATK-SIM900A模块的集成设计。主要设计内容为:主控制器及管脚分配、STM32与ATK-SIM900A模块通信电路设计、SDIO接口电路设计、然后是4G模块协议配置。其次软件方面,主要包括采集信号模块、存储数据功能模块、信号分析处理模块、查询历史数据模块以及报警模块等。应用LabVIEW软件的图式化设计语言,方便操作者能尽快获得监测信息,且对机器的操作也将变得直观明了。将虚拟仪器技术应用到提升机的监测并实现网络数据实时传输,可以使提升机的运行更加安全可靠。最后是关于趋势预测算法的研究,主要包括考虑相关性制动系统的研究与因子归一两部分的研究分析。本课题以故障相关为假设,将影响提升机制动系统的润滑系统与液压站系统作为研究对象,借助相关系数来量化他们之间的影响作用,并建立制动系统的可靠度模型。应用大量的数据验证所建立模型的正确性,所得到的的可靠度函数与故障率函数可作为检修时的参考;其次为了实现能提前预警的目标,研究尝试应用因子归一来进行数据处理。该算法的优点在于能将不同量纲、不同数量级别的数据在同一标准体系下分析它们对某一系统的影响作用。在采用不同的表达函数情况下可得出不同的因子:价值因子、预警因子。相应的监测参数会在超限前期出现高位集中或者低位集中,利用这种特点便可实现预警的目的。本监测系统只对部分项目做出改进,在传输速率与稳定性上4G传输模块有一定的改进,实时性能得到较好的体现。相应的信号分析与处理也做出相应的改进,基本能实现实时监测并做出反馈,从而达到预警的目的。
[Abstract]:Mine hoist as an important part of coal mine production, its safety monitoring is particularly important. At present, more and more mature monitoring means are undoubtedly providing technical support for the data monitoring of hoist. This paper deeply analyzes the basic structure of hoist. Operating characteristics and common fault forms, the monitoring principle of several important parameters is studied in detail and their differences are compared, in order to select the suitable method for measurement and calculation, a complete measurement system should be established. The hardware is the support, the software is the core, and the algorithm is a good bridge to connect the two. First of all, the hardware, mainly including sensor selection. The driver board is integrated with ATK-SIM900A module and matched with USR-LTE-7S4 4G wireless terminal. In addition, it is necessary to consider the influence of environmental factors on the sensor. For the USR-LTE-7S4 4G module, the emphasis is on the integration design with the ATK-SIM900A module. The main contents of the design are as follows:. Main controller and pin allocation. Design of communication circuit between STM32 and ATK-SIM900A module and design of SDIO interface circuit, then 4G module protocol configuration. Secondly, software, mainly including signal acquisition module. Storage data function module, signal analysis and processing module, query history data module and alarm module, etc. The schematic design language of LabVIEW software is used to facilitate the operator to obtain monitoring information as soon as possible. And the operation of the machine will become intuitionistic. The virtual instrument technology will be applied to the monitoring of hoist and the real-time transmission of network data will be realized. It can make the hoist run more safely and reliably. Finally, the trend prediction algorithm is studied. This paper takes the fault correlation as the hypothesis and takes the lubrication system and the hydraulic station system which affect the braking system of the hoist as the research object. The reliability model of braking system is established by quantifying the influence between them with the help of correlation coefficient, and the correctness of the model is verified by a large number of data. The reliability function and the failure rate function obtained can be used as reference for maintenance. Secondly, in order to achieve the goal of early warning, the paper tries to apply factor regression to data processing. The advantage of this algorithm is that it can measure different dimensions. Data of different quantity levels are analyzed under the same standard system. Different factors can be obtained by using different expression functions: value factors. Early warning factors. The corresponding monitoring parameters will appear high concentration or low concentration in the early stage of the limit, using this characteristic can achieve the purpose of early warning. This monitoring system only makes improvements to some items. In the transmission rate and stability of 4G transmission module has a certain improvement, real-time performance can be better reflected. The corresponding signal analysis and processing also make corresponding improvements, can basically achieve real-time monitoring and feedback. In order to achieve the purpose of early warning.
