具体实施方式：
下面结合附图对本发明做更进一步的解释。
如图1和2所示，矿井提升机天轮包括天轮平台1、天轮2、轴承支座6和轴承7，所述天轮2转轴通过轴承7安装在轴承支座6上，轴承支座6安装在天轮平台1上。
本发明的矿井提升机天轮振动性能检测系统包括传感器支架4、激光位移传感器5、传感器盒子8、采集器10和上位机11。所述传感器支架4设置在天轮平台1上，所述传感器支架4底部与天轮平台1之间设有隔震橡胶块3。传感器支架4上设有两个激光位移传感器5，其中一个激光位移传感器5对准天轮2一侧端面，另一个激光位移传感器5对准天轮2径向外缘，激光位移传感器5与天轮的相对位置固定不变，两者之间的距离在激光位移传感器5的量程内。传感器盒子8通过磁铁块9吸附在轴承支座6上，传感器盒子8内设有声音传感器和加速度传感器，所述传感器盒子8未与轴承支座6接触的表面均采用隔音材料制成，够隔离外部声音对传感器盒子8里声学传感器的干扰。激光位移传感器5、声音传感器和加速度传感器信号输出端与采集器10的信号输入端连接，采集器10的信号输出端通过以太网与上位机11的信号输入端连接。
声音传感器内置一个对声音敏感的电容式驻极体话筒，天轮2的轴承7运转时产生的声音信号以轴承支座6为介质传递到传感器盒子8里，被声音传感器接收。声音引起话筒内驻极体薄膜的震动，导致电容变化，进一步引起电压变化。采集分析连续变化的电压就可以间接得到轴承7的运转情况。
天轮轴承7运转时会引起轴承支座6的震动，轴承不同部位磨损程度不同引起的震动幅度也不同，利用加速度传感器捕捉这些震动的变化，并对采集到的信号进行放大转化处理得到电信号，就可以通过采集到的电信号的变化间接获知轴承的磨损程度和磨损部位。
激光位移传感器5、声音传感器、加速度传感器以及采集器10均连接直流电源模块，在采集器10和传感器盒子8中都安装有15VDC的直流电源模块，电源模块为输出电压为15V的锂电池，直流电源模块配备有稳压模块，稳压模块选用稳压芯片LM2596。
所述上位机11中编有分析处理上位机软件，该上位软件优先选用LabVIEW工具编写，在LabVIEW中实现只需调用“读取TCP数据.vi”和“写入TCP数据.vi”即可实现采集器10的数据读写；调用数据“写入电子表格文件.vi”或者“写入文本文件.vi”即可实现采集器10的数据保存。
本发明的基于上述振动性能检测系统的矿井提升机天轮振动性能检测方法：上位机11设定同步时钟，上位机11控制信号通过以太网输入采集器10，实现激光位移传感器5、声音传感器和加速度传感器同步采集数据，激光位移传感器5分别测量天轮2轴向与径向的摆动位移，声音传感器测量轴承7运转声信号，加速度传感器测量轴承7运动信号，采集器10将采集到的数据通过以太网发送至上位机11，上位机11根据接收到的数据信息分析提升机天轮的工作状态。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
