The invention relates to a method for measuring a braking distance (LB) and to a braking distance measuring device (30) for carrying out the method in an escalator (1) or a moving walkway. The braking distance measuring device (30) comprises at least one trigger device (45) which can be connected to a controller (14) of the escalator (1) or the moving walkway, a linear measuring scale (31) which can be optically detected, an optical sensor (35) and an acoustic sensor (36). In order to be able to accurately measure the braking distance (LB), the braking process is optically and acoustically recorded as a sequence of images (60) having a graphically displayed audio track (65). According to the invention, the starting point (68) and the end position (69) of the braking operation noise (51) recorded on the audio track (65) can be precisely associated with the images (62, 63) of the sequence of images (60), and the braking distance (LB) is determined by comparing the different positions of the marking (53) with respect to the measuring scale (31) on the basis of the detected images (62, 63).

    本发明涉及一种用于测量制动距离(LB)的方法以及一种用于在自动扶梯(1)或自动人行道中执行所述方法的制动距离测量装置(30)。制动距离测量装置(30)具有:至少一个能够与自动扶梯(1)或自动人行道的控制器(14)连接的触发装置(45)、可被光学检测的直线测量标尺(31)、光学传感器(35)以及声学传感器(36)。为了能够精确地测量制动距离(LB),制动过程以光学和声学的方式作为具有图形显示的音轨(65)的图像序列(60)被记录。记录在音轨(65)上的制动运行噪声(51)的起始点(68)和结束位置(69)能够被精确地对应于图像序列(60)的图像(62、63),并且基于所检测的图像(62、63),通过将标记(53)相对于测量标尺(31)的不同位置进行比较来确定制动距离(LB)。
