以下结合具体实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
图1为本发明实施例矿井提升系统的尾绳监测装置中监测信号的传输示意图，如图1所示，所述矿井提升系统的尾绳监测装置中监测信号传递的过程为：监测信号依次在霍尔传感器、MCU、无线发射模块、无线接收模块和工业计算机传递；其中，
所述霍尔传感器，用于监测尾绳的转动状况，如是否转动，转动速度多少等，所述霍尔传感器设置有两个，分别为霍尔传感器一和霍尔传感器二，这样，通过两个霍尔传感器的感应信号，MCU能获知所述尾绳是顺时针转动，还是逆时针转动，相应的，作为待感测部件的磁性元件也有两个或两个以上，除了能获知尾绳转动的圈数，还能精确到半圈或小于半圈的角度；
所述MCU，用于采集所述霍尔传感器输出的脉冲信号，并经初步处理后，转发给所述工业计算机；所述霍尔传感器，在尾绳转动时，会输出一 个脉冲信号给所述MCU；所述初步处理，可以包括确定矿井提升系统开始工作时间或停止时间，即尾绳开始旋转或停止旋转时，可确定矿井提升系统开始工作或停止了，也可以包括监测尾绳旋转状态，尾绳旋转状态可以包括是否旋转、旋转方向等；
所述无线发射器，用于将所述MCU发送给所述工业计算机的信号调制到无线信号中进行发射；
所述无线接收器，用于接收无线信号，并解调出所述MCU发送给所述工业计算机的信号，传递给所述工业计算机；
所述工业计算机，用于对来自MCU的信号进行处理。所述处理可以包括：在MCU初步处理的基础上，进一步确定矿井提升系统的开始工作时间或停止时间、尾绳旋转状态、旋转方向、尾绳旋转速度、尾绳旋转加速度等；并在此基础上，绘制尾绳旋转曲线、制作尾绳旋转模拟动画等，也可以确定所述尾绳的工作状态，更具体的详见后面的描述。
所述工业计算机在获得所述尾绳的工作状态后，可以进一步地将所述工作状态发送给所述矿井提升系统的控制装置，便于控制或调整所述矿井提升系统。
另外，所述矿井提升系统的尾绳监测装置还包括高能量电池，所述高能量电池，用于给所述霍尔传感器、MCU和无线发射器供电，因为这三个部件是在生产现场，远离机房，没有市电供应。
所述工业计算机安装有监测诊断分析软件，所述监测诊断分析软件除了可以对MCU发送的数据进行处理，还可实现数据浏览、尾绳旋转曲线绘制、尾绳旋转模拟动画、历史数据查询、故障诊断与报警等功能，具体如下：
(1)尾绳旋转曲线绘制
可根据转动数据绘制图表。图表横坐标为系统时间，纵坐标表示旋转 圈数，默认顺时针转动时为正方向，逆时针转动为负方向。时间轴上用竖长红线划分出提升开始时间、结束时间。判断依据为矿井提升系统静止时尾绳停止旋转，此时霍尔传感器输出信号长时间不变，即在设定时间长度内不变；矿井提升系统开始运行后尾绳开始旋转，霍尔传感器输出脉冲信号。在信号出现变化对应的时间减小一个信号周期，默认从此时矿井提升系统开始运行。提升结束后尾绳静止，此时从信号最后变化对应的时间增大一个信号周期的时间长度，认为此刻为提升结束时间，用竖直红色长线标记。
(2)尾绳旋转模拟动画
监控界面正中为尾绳悬挂装置的模拟动画图，带动画可模拟矿井提升系统运行过程中尾绳悬挂装置的旋转情况。
(3)尾绳停止旋转报警
当霍尔传感器输出的信号停止变化且未到提升结束时间，认为尾绳此时停止旋转或旋转角度过小，此时发出一级警报，停止旋转指示灯变红。在之后规定的时间内仍未到提升结束时间且信号未发生变化，认为尾绳悬挂装置出现故障，此时发出二级警报，停止旋转指示灯开始闪烁并持续发出报警声。
(4)尾绳旋转数据异常报警
尾绳停止旋转故障为缓变故障。对矿井提升系统每次运行得到的尾绳旋转曲线进行比较，第一次提升监测到的曲线认为是初始曲线，当监测到的旋转曲线与初始曲线有较大的差别时，认为尾绳悬挂装置健康程度减小。当两者之间的差别大于30％时，尾绳旋转异常指示灯变红并发出报警。
(5)报警记录查询
每次上述报警发生时，监测诊断分析软件自动将报警信息记入报警数据库，点击监测诊断分析软件右方“报警记录”按钮可查看该报警数据库。
所述工业计算机还用于：检测高能量电池的电量，当所述高能量电池的电量低于5％时电量指示灯变为红色，并持续发出报警。
图2为本发明实施例矿井提升系统的尾绳监测装置中尾绳悬挂装置的示意图，图3为图2的左视示意图；如图2、3所示，尾绳悬挂装置包括销轴1、连接叉2、上吊杆3、监测部件安装架4、连接套5、向心球轴承6、推力球轴承7、密封圈8、下吊杆9和传感器11；
所述上吊杆3用于连接提升容器，具体是通过销轴1和连接叉2固定到提升容器，所述连接叉2通过螺栓螺母固定所述上吊杆3，所述销轴1通过螺栓螺母固定所述连接叉2，所述销轴1固定于所述提升容器；
所述连接套5用于连接所述上吊杆3和下吊杆9，所述连接套5内腔的上端设有向心球轴承6、下端设有推力球轴承7，所述上吊杆3的下端穿入连接套5内腔，并与所述向心球轴承6、推力球轴承7装配，即上吊杆3的外圆轴承档与所述向心球轴承6、推力球轴承7的内圈配合，完成装配后，所述连接套5能以所述上吊杆3的轴线，相对于所述上吊杆3转动。
所述下吊杆9用于悬挂尾绳，所述下吊杆9通过螺栓螺母固定到所述连接套5，能跟随所述连接套5一起转动，所述密封圈8一端固定于所述连接套5，另一端固定于所述下吊杆9，且套设于所述上吊杆3的下端，目的是保护推力球轴承7润滑良好，不受灰尘污染。
所述传感器11用于监测所述下吊杆9的转动情况，所述传感器11固定于所述监测部件安装架4，所述监测部件安装架4下端套设于所述连接套5，所述传感器11的感应头固定于所述监测部件安装架4的内壁、感应方向对准所述连接套5外壁。
所述传感器11具体可以为霍尔传感器，所述连接套5设有与所述霍尔传感器配合的磁性元件，本实施例中，固定于所述连接套5的螺栓上设有永磁块。所述传感器11可以设置两个，除了监测所述下吊杆9是否转动， 还监测所述下吊杆9是顺时针还是逆时针转动；所述永磁块可以设置两块或两块以上，这样，能够精确获取所述下吊杆9的转动角度，因为在监测期间，下吊杆9转动并非都是整数圈。
图4为本发明实施例矿井提升系统的尾绳监测装置中监测部件安装架的示意图，如图4所示，所述监测部件安装架包括安装架本体10，安装架本体10安装有传感器11，所述传感器11包括A、B两个；为了便于安装到上吊杆，所述安装架本体10包括上、下两块，所述安装架本体10的上块安装有MCU 13、无线发射器14和电源12，为了适用于煤矿等场所，所述电源12为本质安全型电源；所述安装架本体10的下块可以套设在所述连接套5上，用于安装传感器11。
所述无线发射器14，用于发送所述MCU 13采集的传感器11的感应信号，为了传输稳定，所述无线发射器14通过数字微波通信发射信号，并采用高速跳频与前向纠错等抗干扰技术。
图5为本发明实施例矿井提升系统的尾绳监测装置在矿井提升系统中的示意图，如图5所示，矿井提升系统包括上天轮、下天轮、滚筒、提升容器A和提升容器B，所述尾绳监测装置的尾绳悬挂装置15和监测部件安装架16位于提升容器A下方，无线接收器17和工业计算机18位于矿井附近的地面，一般是在机房内；
这里，尾绳悬挂装置15可以是图2、3所示的尾绳悬挂装置，所述监测部件安装架16可以是图2、3中的监测部件安装架4。
所述尾绳监测装置，用于在所述矿井提升系统工作时监测所述尾绳的旋转情况，以避免尾绳出现转动受阻或损坏后集聚应力，影响矿井提升系统的运行。
图6为本发明实施例矿井提升系统的尾绳监测装置中无线传输设置跳频的示意图，如图6所示，在发射端，即无线发射器端，先对输入的信号 进行基带调制，通常是频移键控(FSK，Frequency-Shift Keying)调制，然后再与伪随机(PN，Pseudorandom Noise)码控制下的频率合成器产生的本振信号进行混频或变频，得到伪随机跳变的射频信号，所述本振信号是一种射频载波信号，是通过将PN码输入频率合成器进行可变频率合成获得。在接收端，即无线接收器端，用与发射端相同的PN码控制本地频率合成器，将接收的信号与本地频率合成器的信号混频，得到基带调制信号，然后再进行基带解调，恢复出信号。从原理中可以看出，跳频通信是瞬时窄带通信，在每一个频率的驻留时间内，所占的信道的带宽是很窄的，但由于频率跳变的速率比较高，所以从宏观看，跳频系统还是宽带系统，即扩展了频谱。通过设置调频，大大提高了无线信号传输的抗干扰能力。
图7为本发明实施例矿井提升系统的尾绳监测装置的工作流程示意图，如图7所示，所述工作流程包括如下步骤：
步骤701：读取脉冲信号；
MCU从两个霍尔传感器读取脉冲信号，即尾绳转动的感应信号。
