Description

[0001] The utility model relates to the technical field of elevator guidance, in particular to an integrated machine for guiding elevator passengers. Background Art

[0002] When the elevator is in operation, it needs to inform the outside world of its location when moving between different floors, so that passengers can have a better preparation process and improve the efficiency of riding. Usually, the floor where the elevator is located will be displayed on a display panel. In some places with large traffic, although there are multiple elevators, they are still insufficient compared to the huge number of passengers. In this case, the arrival reminder of the elevator needs to be more eye-catching, otherwise passengers are likely to miss the elevator and increase waiting time.
