A method of learning a rescue time period by an elevator system (101). The elevator system (101) comprises an elevator car (103) moved by a machine (111) and a machine brake (120) arranged such that braking of the machine (111) by the machine brake (120) brakes movement of the elevator car (103). The method comprises: releasing the machine brake (120) for at least one test time period, engaging the machine brake (120) at the end of the at least one test time period; detecting a corresponding at least one maximum travel speed of the elevator car (103) reached due to the release of the machine brake (120) in each at least one test time period; checking whether each at least one maximum travel speed is an acceptable speed; and setting a rescue time period based on the checking.
一种通过电梯系统(101)学习救援时间段的方法。所述电梯系统(101)包括由机器(111)移动的电梯轿厢(103)和机器制动器(120),所述机器制动器(120)布置成使得由机器制动器(120)对机器(111)的制动对电梯轿厢(103)的运动进行制动。所述方法包括:在至少一个测试时间段内释放所述机器制动器(120),在所述至少一个测试时间段结束时接合所述机器制动器(120);检测由于在每个至少一个测试时间段内释放所述机器制动器(120)而达到的所述电梯轿厢(103)的对应的至少一个最大行进速度;检查每个至少一个最大行进速度是否是可接受的速度;以及基于所述检查来设置救援时间段。
