  • Patent number: 11577930
    Abstract: The present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.
