Abstract
An automatic elevator call system includes: a wireless signal apparatus installed in an elevator landing zone of an elevator system and broadcasting a corresponding wireless signal around; a counting unit configured to count, after an elevator call request corresponding to an identity of the personal mobile terminal is sent or received, the number of times the elevator call request corresponding to the identity is made within a predetermined time period; and an abnormal elevator call request judgment unit configured to judge, based on a comparison result between the number of times the elevator call request is made and a predetermined threshold, whether the elevator call request corresponding to the identity is a normal elevator call request operation. The present invention can effectively determine an intentional or unintentional abnormal elevator call request operation of a passenger.
