In one embodiment, the circuit board 7 and the display screen 4 are integrated into the same module, so that the assembly space is saved while the cost is reduced.

In the embodiment, the calling landing buttons 3, the display screen 4, the arrival prompting lamp 5, the fire switch 6 and other functional modules are controlled by the circuit board 7 in a centralized manner, the control panel input interface is connected with the hoistway trunk branch line interface and communicated with the control cabinet, and the control panel output interface is respectively connected with the calling landing buttons, the display module, the arrival lamp, the fire switch and the base station lock.

The basic control principle is as follows: taking the passenger needing the up call as an example, when the passenger presses the up call button 31, the call signal transmits the up signal to the upper LED lamp and the control cabinet through the circuit board 7, the upper LED lamp is normally on, the lamp shade 52 of the upper LED lamp is lightened, the lower LED lamp is kept in a normally off state, and the passenger outside the hall is informed that the elevator is being dispatched.

The control cabinet receives the uplink signal and then starts to dispatch the elevator for the elevator calling layer, the floor signal where the elevator car is located is transmitted to the circuit board 7, the circuit board 7 transmits the signal to the display screen 4, and the display screen 4 displays the information of dispatching the elevator floor and informs the information of the floor where the elevator car is located outside the hall.

After the elevator arrived the calling floor, the switch board arrived station signal transmission with the elevator for circuit board 7, and circuit board 7 control upper end LED lamp scintillation tells the visitor outside the hall that this elevator arrived station, and after the passenger got into car room sedan-chair door and closed, the upper end LED lamp was extinguish, and whole duty cycle ended.

The fire switch 6 is out of work under the normal operating condition of elevator, when the conflagration breaing out, presses the fire switch 6, through circuit board 7 with fire service signal transmission to switch board, the elevator gets into the fire service mode.

When the elevator needs to remove the fire service mode, the fire switch 6 is pressed again to reset the elevator, the signal is transmitted to the control cabinet through the circuit board 7, and the elevator removes the fire service mode.

In one embodiment, the integrated multifunctional elevator hall calling device is installed by the following steps:

1) checking whether each functional module is assembled on the pre-assembly module to ensure that the assembly is finished;

2) testing whether each functional module works normally;

3) forming holes on the outer wall of the hall according to the civil engineering hole forming positions for electric wiring;

4) mounting a back plate, and fixing the back plate by using expansion screws;

5) the pre-assembly module is buckled on the back plate to ensure that the panel completely covers the back plate;

6) and the inner hexagon screw is locked, so that the panel cannot move and the installation is finished.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
