Display screen or portion thereof with transitional graphical user interface for displaying elevator information

Elevator screen

Provided is a communication system and a communication method for use in an elevator system, which belong to the field of elevator intelligent control technologies. The communication system of the present invention comprises: a first bluetooth module mounted in an elevator landing area of the elevator system and a second bluetooth module mounted in an elevator car of the elevator system. The communication system and the communication method of the present invention can realize that a passenger completes an elevator calling operation in a completely hand-free mode, which is easy to realize and is low in cost.

Communication system and method for elevator system

The present invention relates to determining the movement of a passenger relative to an elevator landing area, which belongs to the field of elevator intelligent control technologies. An automatic elevator calling system of the present invention comprises: a first wireless signal module installed in an elevator car, which is used for broadcasting a first wireless signal; wherein the first wireless signal module is further used for receiving information regarding the movement of a passenger relative to the elevator car, and the information regarding the movement is determined based on the change in a signal strength of the first wireless signal received by a personal mobile terminal carried by the passenger.

Determination for motion of passenger over elevator landing area

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.

Automatic elevator calling system and a method for controlling automatic calling elevator

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.

Determination of non-normal elevator calling request in an automatic elevator calling request system

The present invention relates to the determination of the movement of a passenger relative to an elevator car and belongs to the field of elevator intelligent control technologies. The present invention acquires information about the movement of a passenger relative to an elevator car, wherein the information about the movement of the passenger relative to the elevator car is determined based on a change in the signal strength of a first wireless signal received by a personal mobile terminal carried by the passenger and a change in first floor information and/or traveling direction information.
