Intelligent projection system based on projector

Abstract

The invention discloses an intelligent projection system based on a projector. The system comprises a projection receiving screen, a wireless terminal and the projector. The projector comprises a wireless receiving unit, a decoding unit, an MCU unit, a storage unit, a display unit, a key unit and a projection unit. The wireless receiving unit is sequentially connected with the decoding unit and the MCU unit. The MCU unit is connected with the storage unit, the display unit, the key unit and the projection unit. The wireless terminal sends data to the projector through the wireless receiving unit. The projector receives items displayed through the display unit, selects the items through the key unit and controls the projection unit to play the received data after storing and decoding the received data. The projector can be connected with the wireless terminal nearby at any time and has the real-time receiving and sending functions, the data of the wireless terminal can be projected on the projection receiving screen in real time, the connection range is enlarged, and the data can be shared and transmitted in real time conveniently.

Description

technical field [0001] The invention relates to an intelligent projection system based on a projector, which belongs to the technical field of projection equipment. Background technique [0002] At present, the projection system has become an indispensable part of life and office. In various meetings, when relevant documents need to be displayed, the projection system can meet the most fundamental needs of people and share the files with everyone present at the meeting. Thus , making the projection system widely used in homes, offices, schools and entertainment venues. [0003] A traditional projection system includes a projection receiving screen, a projector, and a computer connected to the projector. The screen is generally set at the position opposite to the lens of the projector, and the projector is generally connected to the computer by cable, thereby outputting the picture in the computer. projection. This traditional method can simply and directly project the data...

AI Technical Summary

Problems solved by technology

However, despite this, it still does not solve the problem of signal reception by the projector during the projection process. Similarly, the system still does not solve how to reduce the dependence on the computer during transmission, and does not provide how to establish wireless connections with other terminals for real-time monitoring. The problem of data transmission, so there are still limitations

[0006] To sum up, the existing projection system can only rely on computer input signals, the signal input method is single, it cannot establish wireless connection with other terminals, and cannot transmit the data in the terminal in real time, the system efficiency is low
