The invention discloses an elevator balance coefficient diagnosis method which comprises the following steps: S1, when an elevator is in a no-load state, measuring a current no-load zero-speed maintaining torque current value Iz0t; s2, calculating a no-load deviation ratio delta z; s3, whether the no-load deviation ratio delta z is larger than a preset threshold value or not is judged; if the no-load deviation ratio delta z is not greater than the threshold value, the diagnosis is ended; if the no-load deviation ratio delta z is greater than the threshold value, entering the step S4; s4, when the elevator is fully loaded, the current full-load zero-speed maintaining torque current value IzLt is measured; s5, the current balance coefficient Lbt of the elevator is calculated; s6, whether the current balance coefficient Lbt of the elevator is within the range of 0.4-0.5 or not is judged; if the balance coefficient is within the range, the balance coefficient is normal and the diagnosis is ended; if the range is exceeded, the balance coefficient is abnormal, and alarm information is output. Compared with the prior art, the balance coefficient of the elevator can be monitored and diagnosed in the normal service providing process of the elevator, and warning information is provided for an owner or a maintainer.

    本发明公开了一种电梯平衡系数诊断方法,包括:步骤S1,当电梯空载时,测定当前的空载零速维持转矩电流值Iz0t;步骤S2,计算空载偏差率δz;步骤S3,判断空载偏差率δz是否大于预设阈值;若空载偏差率δz不大于阈值,诊断结束;若空载偏差率δz大于阈值,进入步骤S4;步骤S4,当电梯满载时,测定当前的满载零速维持转矩电流值IzLt;步骤S5,计算电梯当前的平衡系数Lbt;步骤S6,判断电梯当前的平衡系数Lbt是否在0.4~0.5范围内;若在范围内,平衡系数正常,诊断结束;若超出范围,平衡系数异常,输出报警信息。与现有技术相比本发明能在电梯提供正常服务过程中监控和诊断电梯的平衡系数,并向业主或维护方提供警示信息。
