HOLOGRAPHIC EXTERNAL CALLING DEVICE FOR ELEVATOR

Abstract

A holographic external call device for an elevator, which includes a device shell. One side of the device shell is provided with a sensor mounting hole, and a gesture sensor is installed in the sensor mounting hole. An optical module is installed, one side of the optical module is provided with two screen installation grooves, the two screen installation grooves are both installed with a screen, and the bottom side of the optical module is provided with a main board. The screen produces an image after power on, which affects the light reconstruction in the optical module to generate an image in the air, and then the finger clicks on the image in the air. The gesture sensor will sense the gesture and send the command for the main board, addressing cross-contact infection problem caused by using the elevator outbound button to call the elevator without actual physical contact.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the example embodiments in conjunction with the accompanying drawings in the example embodiments. Obviously, the described embodiments are only a part of the example embodiments, not all examples.

[0017] Referring to FIGS. 1-3, a holographic external call device for elevators includes a device housing 1, a sensor mounting hole 3 is opened on one side of the device housing 1, a gesture sensor 4 is installed in the sensor mounting hole 3, and the device housing 1 is installed optical module 5, one side of the optical module 5 is provided with two screen mounting slots 6, and the screen 7 is installed in the two screen mounting slots 6, the bottom side of the optical module 5 is provided with a main board 8, which is located in the device. Inside the device housing 1, a device mounting board 2 is installed on the bottom side of the device housing 1. The device mounting board 2 is adapted to the device housing 1. The holographic external device is used to generate images in the air, and touch-free clicks and other gesture operations are performed. Elevator interaction realizes the function of contactless calling elevator.

[0018] In an example embodiment, both sides of the device housing 1 are fixedly installed with fixing plates 11, and fixing holes are opened on one side of the two fixing plates 11. The fixing plate 11 and the fixing holes on the fixing plate 11 are arranged to facilitate the installation of the device. The housing 1 is fixedly installed in the elevator, which is convenient for installation. In the present invention, a reinforcing rib is fixedly installed on one side of the fixed plate 11.

[0019] In an example embodiment, a plurality of first connecting blocks 9 are installed on one side of the device mounting plate 2, and a plurality of second connecting blocks 10 are installed on one side of the device housing 1. The two connecting blocks 10 are matched, and the device housing 1 and the device mounting board 2 are connected by a plurality of first connecting blocks 9 and a plurality of second connecting blocks 10, and it is convenient to remove when the internal installation and maintenance are required.

[0020] After the screen 7 is powered on, an image is generated, which affects the light reconstruction in the optical module 5 to generate an image in the air, and then the finger clicks on the image in the air. At this time, the gesture sensor 4 in the device will sense the gesture and send the command to the main board 8. The main board 8 sends a signal: a signal is sent to the screen 7, the content of the screen 7 changes, and the feedback is given to the user, forming a closed loop of human-computer interaction, and a signal is sent to the elevator control system to tell the control system that someone is going to take the elevator and go through the above process. We have realized the function of clicking the image in the air to call the elevator to call the floor. In the elevator scene, the holographic external device is used to generate the image in the air, and the touch-free click and other gesture operations are performed to interact with the elevator to achieve contact-free. The function of calling the elevator, the fixed plate 11 and the fixing holes on the fixed plate 11 are arranged to facilitate the fixed installation of the device casing 1 in the elevator, and the installation is convenient, and the device casing 1 and the device mounting plate 2 pass through a plurality of first connecting blocks 9. It is connected with a plurality of second connecting blocks 10, and it is convenient to dismantle when internal installation and maintenance are required.

[0021] The above are only the preferred specific embodiments, but the protection scope is not limited to this. Anyone familiar with the technical field within the technical scope of the present disclosure, according to the present claims. The technical solution of the new type and the concept to be equivalently replaced or changed shall be covered by the scope of protection of the claims.
