The elevator head sheave vibration anomaly detection system comprises a first radar detection device and a second radar detection device, and each of the first radar detection device and the second radar detection device comprises a sensor support, a millimeter wave radar sensor and a data return module. The millimeter wave radar sensor and the data return module are installed on the sensor support. The millimeter-wave radar sensor of the first radar detection device directly faces the bearing center of the head sheave, and the millimeter-wave radar sensor of the second radar detection device is aligned with one side end of the head sheave; the distance between a millimeter-wave radar sensor of the radar detection device and the head sheave is kept in a millimeter-wave radar data undistorted range; synchronous clocks are arranged in the upper computer and the millimeter wave radar sensor. The head sheave vibration abnormal data can be remotely detected in real time, so that the working state of the head sheave is monitored in real time, the safety and stability of the elevator are ensured, the detection cost is low, the detection result is slightly influenced by the environment, and the detection precision is high.

    本发明公开一种基于毫米波雷达的提升机天轮振动异常检测系统及方法,包括第一、第二雷达检测装置,所述第一、第二雷达检测装置均包括传感器支架、毫米波雷达传感器和数据回传模块,所述毫米请波雷达传感器和数据回传模块安装在传感器支架上;第一雷达检测装置的毫米波雷达传感器正对天轮的轴承中心,第二雷达检测装置的毫米波雷达传感器对准天轮一侧端;雷达检测装置的毫米波雷达传感器与天轮之间的距离保持在毫米波雷达数据不失真的范围内;上位机和毫米波雷达传感器内置有同步时钟。能够实时远程对天轮振动异常数据进行检测,从而实现对天轮工作状态的实时监测,以确保提升机的安全性和稳定性,检测成本低,检测结果受环境影响小,检测精度高。
