Embodiment 1

[0047] The embedded system adopted by the terminal control device 1 in this embodiment includes a micro-processing module, a memory, a display module, a network interface and the like. Micro-processing module 12 adopts S3C2410 microcontroller; its memory 16 is 64MRAM and 128M NAND flash; display module 15 and input module 11 adopt 10.1-inch liquid crystal display with touch function, and are also provided with network interface 14 and USB2.0 interface , VGA differential signal input RJ45 and other interfaces. The remote controlled server end 2 is a general-purpose computer.

[0048] The terminal control device 1 uses QT to write programs, and realizes the mouseMoveEvent, mousePressEvent, mouseReleaseEvent, and mouseDoubleClickEvent mouse events of the QWidget class through writing. This event collects coordinate information after mouse movement, mouse button click information, mouse button release information, and mouse button double-click information respectively. The speci...

Embodiment 2

[0058] In this embodiment, the dual-screen switching and remote control technology based on the embedded system is applied to a conference system based on the terminal of the embedded system.

[0059] The present invention is used to implement the speech application sub-function in the conference system. When the speaker applies for a speech to the terminal control device of the conference chairman through the terminal control device 1, the remote server terminal 2 is controlled to accept the terminal control device 1 after receiving the permission command of the conference chairman. request. The terminal control device 1 can switch to display the screen of the remote controlled server 2. At this time, the speaker can operate the content on the display module 15 of the terminal control device 1, and all operations will be transmitted to the remote controlled server in the same way. 2, so as to carry out remote control, the speaker can complete various operations such as direct...

Abstract

The invention discloses remote control equipment based on an embedded system. The remote control equipment comprises a terminal control device and a remote controlled server end, wherein a remote controlled server is connected with the terminal control device through an internet. The terminal control device comprises a switching control module. According to the remote control equipment, signals are controlled to switch through a switching control module; remote transmission is carried out to a controlled computer desktop through a network wire; and an interactive operation can be carried out to the remote computer desktop through a local mouse or by touching. With the remote control equipment, the remote control can be achieved through the embedded system which has relatively low hardware configuration and has a small kernel mode; a remote control technical scheme with higher convenience and higher flexibility is provided; and the application based on the internetworking of embedded equipment is expanded. And the invention also discloses an implementation method of the remote control equipment based on the embedded system.

Description

Technical field [0001] The invention involves dual -screen switching and remote control technology of embedded systems, especially a remote control device and its implementation method based on embedded systems. Background technique [0002] The so -called remote control refers to the technology of a computer (main control Remote / client) on the Internet to control the technology of another computer (controlled Host / server). The remote here is not a literal long distance.Generally, remote computers are controlled through the network. Most of the time, remote control we are talking about often refers to the remote control in the local area network. When the operator performs remote control on the Remote client, it is like sitting on the controlled computer screen.The same as before, at this time, the desktop environment of the controlled computer was displayed on its own computer, and the remote computers allocated, modified, activated, and closed the application through local comp...
