Problems solved by technology

[0002] At present, the method of modifying the floor display of the elevator is to send it to the construction site for installation after burning it in the factory. It is often encountered that the floor display on the display needs to be modified on site, so that the program on the display needs to be re-programmed. Engineers go to the site to burn, and some send the display back to the factory for re-burning. In many cases, the on-site display has already been installed, and the communication cables are all in the well, so it is difficult to take it out to communicate with the burning equipment.
Going back and forth in this way not only wastes manpower, but also wastes time; secondly, when the monitor is working, it needs to be connected to the graphics card in the host with a video cable, and the video cable and the keyboard cable, mouse cable, network cable and audio cable connected to the host make the host The rear connection is cumbersome and prone to failure, and the movement of the display is limited by the length of the video cable, which is very inconvenient to use

Embodiment 1

[0029] A bluetooth wireless display system, in overall design, the system is mainly composed of two parts: a host part and a display terminal. The host part is responsible for sending control commands and display data, and the display terminal is responsible for receiving and displaying. System structure such as image 3 shown.

[0030] The host part is equipped with a Bluetooth module, which is connected to the PC host through a USB interface. The display terminal consists of a control module with an ARM microcontroller as the core, a Bluetooth module, an OLED display and an OLED controller.

[0031] The host part and the display terminal communicate through the RFCOMM protocol layer of the Bluetooth protocol stack. The RFCOMM protocol provides serial data transmission and can simultaneously maintain up to 60 connections between 2 Bluetooth devices, and can simultaneously support legacy serial port applications and OBEX protocols in other applications. The structural bloc...

Embodiment 2

[0040] This embodiment also provides a solution for WiFi control, such as Image 6 As shown, the sensor interface 1 is used to connect external sensors to collect floor information; the microprocessor 2 is connected to the sensor interface 1 for data processing; the WiFi controller 3 is connected to the microprocessor 2, for sending network data; the switch chip 4, the switch chip 4 is connected to the WiFi controller 3, and is used to connect several devices with network interfaces to the same local area network; the power supply 5 and the power supply 5 are respectively connected to the microprocessor 2 and WiFi The controller 3 and the switch chip 4 are connected, and the power supply supplies power to the microprocessor 2, the WiFi controller 3, and the switch chip 4; the camera network interface 6, and the camera network interface 6 is connected to the switch chip 4 for connecting an external camera; digital hard disk The video recorder network interface 7, the digital ha...

Embodiment 3

[0048] see Figure 8 , is a flow chart of the steps of an embodiment of the Bluetooth communication connection method for the display provided by the present invention. In this embodiment, the Bluetooth communication connection method of the display mainly includes the following steps: Step S201: After the display is powered, it is judged whether a Bluetooth communication connection request sent by an external device is received. When the display receives the Bluetooth communication connection request sent by the external device, execute step S202; when the display does not receive the Bluetooth communication connection request sent by the external device, execute step S203. Step S202: Use the display as a slave device, and use the external device that sends a Bluetooth communication connection request as a master device, and control the display to work in a passive mode to conduct point-to-point Bluetooth communications with the external device. Step S203: Control the The di...

Abstract

The invention provides a new-function display for modifying floors via Bluetooth wireless communication. The display comprises a client, a storage module, a Bluetooth processing module, a communication module circuit, an audio module, a central processing module and a display module. The display is directly communicated by adoption of a Bluetooth technology, and to-be-set floor information is directly modified by the display through Bluetooth wireless communication. The display is simple to operate; the client is provided with an APP; data transmission and field updating are carried out through the APP without dismantling; and the workloads of the manufacturers and maintainers are lightened.
