Abstract

The utility model discloses an electron conference table tablet, include: the device comprises a shell, a back plate, a circuit board, a chip, a display screen, a serial port module and a wireless module; the circuit board is arranged in the shell; the display screen, the chip, the serial port module and the wireless module are arranged on the circuit board; the shell is provided with an opening matched with the display screen, and the display screen is embedded into the opening of the shell; the display screen, the chip, the serial port module and the wireless module are respectively electrically connected with the circuit board; the back plate is mounted on the housing. The utility model can transmit the updating data to the electronic conference table cards around each electronic conference table card in a multi-point networking data transmission mode, thereby being capable of bypassing the shelters to update the data; because each electronic conference table card only needs to transmit the updated data to the electronic conference table cards around the electronic conference table card, the required transmission distance is not far, and low-power and low-cost electronic components can be adopted, so that the cost is reduced.

Description

Electronic conference table board

Technical Field

The utility model relates to an electron table tablet technical field specifically is an electron conference table tablet.

Background

The electronic conference table board is a sign arranged on a conference table and is mainly used for leaders, participants and names, units, jobs and the like of participants. The variety is various and the function is different.

The existing electronic conference table card adopts a one-to-many broadcasting mode to update data, but has the following problems:

firstly, the problem that the communication is blocked by a shelter cannot be solved;

and secondly, a communication module with higher cost is needed for long-distance communication.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art and providing an electronic conference table card capable of carrying out point-to-point data transmission.

The utility model discloses a realize through following technique:

an electronic conference table card comprising: the device comprises a shell, a back plate, a circuit board, a chip, a display screen, a serial port module and a wireless module; the circuit board is arranged in the shell; the display screen, the chip, the serial port module and the wireless module are arranged on the circuit board; the shell is provided with an opening matched with the display screen, and the display screen is embedded into the opening of the shell; the display screen, the chip, the serial port module and the wireless module are respectively electrically connected with the circuit board; the back plate is mounted on the housing.

Further, the display screen is mounted on one side of the circuit board; the chip, the serial port module and the wireless module are arranged on the other side of the circuit board.

Further, the chip is an nRF2401 chip.

The utility model discloses a theory of operation: any electronic conference table card receives the updated data through the serial port module or the wireless module, transmits the updated data to the chip through the circuit board, and then transmits the updated data to the display screen for display; then, the updated data is transmitted to the wireless module, and the updated data is transmitted to the wireless module of another electronic conference table card through the wireless module; the above process is repeated until the data update of all the electronic conference table cards is completed.

The utility model has the advantages that: the utility model can transmit the updating data to the electronic conference table cards around each electronic conference table card in a multi-point networking data transmission mode, thereby being capable of bypassing the shelters to update the data; because each electronic conference table card only needs to transmit the updated data to the electronic conference table cards around the electronic conference table card, the required transmission distance is not far, and low-power and low-cost electronic components can be adopted, so that the cost is reduced.
