Method and device for detecting abnormity of motor lock body of intelligent lock
The invention discloses a method and a device for detecting abnormity of a motor lock body of an intelligent lock. The method comprises the following steps: recording a first action duration of the lock body from motor starting to locked-rotor; if the second action duration of the lock body from motor starting to locked-rotor in a historical record reaches the first set number, the average duration and the shortest duration of the lock body are determined; if the first action duration is less than the set normal action duration, additionally supplying power to the motor for a set power supply duration; acquiring a sampling current value acquired from the motor current at a set frequency, wherein the acquisition time is from the starting of the motor to the end of the power supply duration; determining a slope between two adjacent sampling current values relative to the sampling time; if the second set number of continuous slopes are larger than the preset slope, the maximum output current of the motor is limited within the range of the set limiting current, whether the lock body is abnormal or not can be accurately detected according to the action duration of the lock body and the current change slope, and therefore the situation that the motor is damaged due to too large current is avoided; the method can be widely applied to the field of intelligent door locks.
本发明公开了一种智能锁电机锁体异常的检测方法及装置，方法包括：记录锁体从电机启动到堵转的第一动作时长；若历史记录的锁体从电机启动到堵转的第二动作时长达到第一设定个数，则确定其平均时长与最短时长；若第一动作时长少于设定的正常动作时长，则向电机额外供电设定的供电时长；获取以设定频率对电机电流采集的采样电流值，采集时间为从电机启动至供电时长结束；确定相邻两个采样电流值之间关于采样时间的斜率；若存在连续第二设定个数的斜率大于预设斜率，则将电机的最大输出电流限制在设定的极限电流的范围内，本发明根据锁体动作时长与电流变化斜率可以精准检测锁体是否异常，进而避免因电流过大损害电机，可广泛应用于智能门锁领域。
