[0102] This utility model also relates to an elevator group control system, which includes the aforementioned double-sided screen display device for elevators.

[0103] The application of the dual-screen display device of this utility model in a group control environment will be further described below.

[0104] When a passenger needs to go to a specific floor, they press the desired floor button on the elevator call device. At this time, the request signal is transmitted to the elevator group control system via the CAN bus. The elevator group control system can dispatch an elevator and transmit the dispatch information-related signals to the call device via the CAN bus. The call device can display and announce the elevator number the passenger will be taking. At the same time, the elevator group control system sends a command signal to the corresponding elevator control board. The elevator control board can control the operation of the corresponding elevator based on the command signal, such as ascending or descending, to go to the passenger's current floor and then to the designated floor after the passenger takes the elevator. Furthermore, the elevator control board can transmit display signals to all the double-sided screen displays of this elevator, so that the double-sided screen displays can show the destination floor that the elevator is about to go to.

[0105] Accordingly, once a passenger completes the elevator call operation, even if the passenger confuses the elevator number of the destination elevator, the dual-screen display device of this utility model can display the destination floor that the corresponding elevator is about to go to in real time. This can prevent passengers from taking the wrong elevator and greatly reduce the behavior of repeatedly calling the elevator because the passenger does not know the elevator number of the destination elevator.

[0106] Furthermore, this utility model's dual-screen display device uses dual-sided displays, and the displayed information is exchanged in real time via CAN communication. It can display not only the elevator number but also the floor the elevator is about to reach. Additionally, it can display corresponding fault prompts in case of elevator malfunction.

[0107] Furthermore, this invention's double-sided screen display device can unify materials, optimize production and warehousing, and eliminates the need for installation based on elevator numbers. In particular, it can significantly improve installation efficiency when there are a large number of group-controlled elevators.

[0108] Furthermore, the information displayed by the dual-screen display device of this utility model can be adjusted according to actual needs. The displayed information includes, but is not limited to, elevator number, the floor to be visited, elevator operating status, whether there is a malfunction, and whether it is fully loaded.

[0109] In addition, when the elevator is under maintenance or there are other malfunctions, such as earthquakes, full load, overload, fire, etc., the dual-screen display device can display corresponding icons or information.

[0110] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and descriptive purposes. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed, and it will be apparent that many modifications and variations can be made in light of the foregoing teachings. The exemplary embodiments were chosen and described to explain certain principles of the invention and its practical application, thereby enabling those skilled in the art to make and utilize various exemplary embodiments of the invention, as well as their different alternatives and modifications.
