Problems solved by technology

[0004] However, the current elevator door projection advertising machine turns off the entire projection screen at the moment the elevator door is opened, and only opens the entire projection screen after the elevator door is completely closed. Uncomfortable sensory experience, especially when the projection screen is relatively bright, will also burden the eyes of passengers and have a greater impact

Embodiment 1

[0040] figure 1 It is a flow chart of an elevator-based projection method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of opening / closing doors of an elevator, and the method can be executed by a projection device. like figure 1 As shown, the method specifically includes the following steps:

[0041] Step 110, receiving the elevator status information sent by the elevator controller;

[0042] Exemplarily, in this embodiment, the projection device is inside the elevator, and the projection is projected on the inner wall of the elevator door for illustration. Similarly, the present invention can also be used for the projection device outside the elevator, and the projection is projected on the outer wall of the elevator door. situation.

[0043] Exemplarily, the elevator status information sent by the elevator controller can be received through wireless or wired methods such as WIFI, Bluetooth, RS485, CAN, etc. The elevator...

Embodiment 2

[0049] figure 2 The flowchart of an elevator-based projection method provided by Embodiment 2 of the present invention is a further optimization of the projection method in Embodiment 1. The method specifically includes the following steps:

[0050] Step 210, receiving the elevator status information sent by the elevator controller;

[0051]Exemplarily, the elevator status information sent by the elevator controller can be received through wireless or wired methods such as WIFI, Bluetooth, RS485, CAN, etc. The elevator status information can include elevator door opening information, elevator door closing information, elevator door pause information, elevator curve Information, floor information, elevator single-door execution information, elevator double-door execution information, elevator door opening time, elevator door closing time and other information. Elevator door opening / closing information may include elevator door opening / closing time, elevator door opening / closi...

Embodiment 3

[0066] Embodiment 3 of the present invention is a further optimization of the projection method in Embodiment 2. The method further includes the following steps on the basis of Embodiment 2:

[0067] Step 310, during the moving process of the elevator door, if the elevator suspension information is received, the projection screen is suspended;

[0068] Exemplarily, when the elevator door is opening, if the elevator pause information is received, the elevator door stops the door opening process, and at the same time the projection device controls the micromirror area to suspend the current action to realize the pause movement display of the projected picture. The current projected picture is The projection screen that is frozen when the elevator stops opening the door; when the elevator door is closing, if the elevator pause message is received, the elevator door will stop closing the door, and the projection device will control the micromirror area to suspend the current action...

Abstract

The present invention discloses an elevator-based projection method, device and system, the system comprises: receiving elevator state information sent by an elevator controller; determining elevatorgate state information according to the elevator state information; acquiring corresponding elevator curve information; controlling a projection range of projection images to move synchronously with an elevator door according to the elevator curve information. The method, device and system realizes the effect of gradually closing or opening of the projection images during the opening or closing process of the elevator door, thereby enhancing passengers viewing experience.

Description

technical field [0001] The embodiments of the present invention relate to the field of elevators, and in particular to a projection method, device and system for elevator doors in the field of elevators. Background technique [0002] The traditional elevator door does not display any content. In order to realize the efficient use of the elevator door, the way of pasting the promotional picture book has appeared on the elevator door. However, the elevator brochure needs to be replaced frequently, and the display content is single, which cannot provide a variety of display effects. Based on this, the elevator door projection advertising machine came into being. [0003] The main purpose of the elevator door projection advertising machine is to store the advertiser's promotional pictures or promotional videos in the internal memory, and project the promotional pictures or promotional videos to the upper position of the inner or outer wall of the elevator door. When the elevato...
