The method provides a brake wheel rotating angle detecting method for the braking process of an elevator brake. The method is characterized by comprising the following steps that multiple equal-interval marks are arranged at the position, close to the edge, of a brake wheel, while the elevator brake carries out braking, an industrial camera is used for shooting the braking process of the brake wheel in the elevator brake, photographed video image data formed by n frames of images are transmitted to a computer, and the computer utilizes an image processing algorithm to calculate and obtain a brake wheel rotating angle and displays the brake wheel rotating angle. According to the method, non-contact measuring is achieved, a measuring device does not influence performance of the brake, destructive refitting of the brake is not needed, installing is convenient, moreover, parameters can be upgraded automatically during calculation of each time, the influence on a detecting system by environment change is reduced, and the detecting system works stably and beneficially for a long term.

    本发明提供了一种电梯制动器制动过程制动轮转角检测方法,其特征在于,包括以下步骤:在制动轮上接近边缘的位置设置多个等间距的标记,在电梯制动器制动的同时,使用工业摄像机对电梯制动器中制动轮的制动过程进行拍摄,并将拍摄到的由n帧图像组成的视频图像数据传入计算机,由计算机利用图像处理算法计算得到制动轮转角并进行显示。本发明实现了非接触测量,测量装置不会影响制动器的性能,无需对制动器进行破坏性的改装,安装方便,而且可以在每次计算时自动更新参数,减小了环境改变对检测系统的影响,有利于检测系统长期稳定工作。
