The invention belongs to the technical field of elevator detection, and discloses an elevator star sealing function detection method and device, equipment and a storage medium. During elevator star sealing function detection, a resistor connected to a main contact of an operation contactor in parallel and a star sealing contactor contact or a traction machine form a current path; therefore, a current path can be formed between any two output ends of the three output ends of the frequency converter under the two conditions of normal closing and abnormal open circuit of the star sealing contactor, and changes of feedback current flowing through the current path are different under the two conditions. Whether the star sealing contactor is normally closed or not can be judged only by controlling the voltage pulse signal output between the two output ends of the frequency converter and detecting the feedback current change signal on the current path, elevator star sealing function detection is completed, the detection speed is improved, elevator slipping is not needed for testing, and the user experience feeling can be improved.

    本发明属于电梯检测技术领域,公开了一种电梯封星功能检测方法及装置、设备、存储介质,在进行电梯封星功能检测时,通过在运行接触器主触点上并联的电阻与封星接触器触点或曳引机形成电流通路,从而在封星接触器正常闭合和异常开路这两种情况下,均可以实现在变频器的三个输出端中任意两个输出端之间形成电流通路,两种情况下电流通路中所流经的反馈电流的变化有所差异,只需控制变频器其中两个输出端之间输出电压脉冲信号,检测电流通路上的反馈电流变化信号,即可判定封星接触器是否正常闭合,完成电梯封星功能检测,检测速度得以提高,且无需溜梯进行测试,可以改善用户体验感。
