Wireless Image Monitoring System for Internet Lectures {Wireless Image Monitoring System for Internet lectures}

Since a conventional notebook must be connected to the display device by wire, a lecturer who lectures while moving a lecture room has a lot of trouble to connect the notebook with the display device every time for presentation using the notebook in class. In addition, another additional device is required for presentations using the Internet, and the display device cannot be controlled through the notebook.

The present invention has been made to solve the above problems, and therefore, an object of the present invention is to connect to the monitoring device prepared in the classroom using wireless LAN communication without a separate wired connection to the notebook and synchronized with the notebook. The screen can be displayed. In addition, by using the Internet address translation module mounted inside the system it is possible to use the wireless Internet without additional devices.

By adding an additional PCMCIA card to the notebook, the instructor can lecture anywhere in the classroom, wirelessly provide the Internet necessary for the lecture, and provide a simple control program for the instructor to directly control the lecture monitoring system through the notebook. to provide. Therefore, it is an object of the present invention to provide a lecture monitoring system equipped with a remote control function to provide a more realistic class to the students taking the class.

Hereinafter, a wireless image processing and internet lecture monitoring apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, FIG. 1 is an overall configuration diagram of a wireless video and internet lecture monitoring system. When the connection is established by requesting the connection to the monitoring device 13 with the notebook 12 equipped with the wireless LAN card 11, the wireless image and internet data can be monitored through a PC monitor or a beam project or a TV monitor 14. Can be.

Referring to FIG. 2, FIG. 2 is a controller of a lecture monitoring system. First, the manager's lecture monitoring system control program 20 is installed in a notebook to transmit wireless data to the monitoring device. If you press the icon of the connection selection setting mode 22 of the place to be connected, the item “Disconnect (21)” is activated, and the connection is made to the monitoring device, and as soon as the connection is made, the entire screen shown in the notebook is sent to the monitoring device. . Clicking the item "Disconnect 21" sends a termination request message to the monitoring device side. Changes in the monitor and laptop screen are always the same. Each monitoring device can have a different resolution, so adjust the settings automatically to match the resolution of the monitoring device you are accessing. If not, manually add an item to change the resolution of the notebook.

Referring to the driving module, the lecture monitoring control program 20 is loaded into the memory 61 at the same time as booting up the switch, and waits for the connection of the notebook. When the notebook is connected to the monitoring device, the monitor of the monitoring device displays the notebook screen in full screen without the monitoring device's screen. Since the screen of the notebook is displayed in the monitor part of the monitoring device in real time, the notebook and the monitoring device are synchronized to perform one-to-one communication. When the notebook receives a shutdown request, it disconnects and waits for the next notebook to connect.

Referring to Figure 3, the internal configuration diagram of the lecture monitoring device of the present invention is divided into three parts. This is the main data processor 40, the internet processor 50, and the image processor 60. The main board 30 of the monitoring device for wireless communication with a notebook for transmitting wireless image data is used for interworking the above three modules. The main data processing unit 40 is a PCMCIA module 12 for easily connecting the wireless LAN card 11, and a receiving unit 43 for receiving a wireless LAN signal and data transmitted by a notebook from the PCMCIA module 12 and transmitting the data to a hard disk. And a connection unit via a storage device 44 which receives the wireless image data transmitted by the notebook during LAN communication from the receiving unit 43 and stores the data sent from the image processing unit 60 and the data sent from the internet processing unit 50. Data is sent to (45). The Internet processing unit 50 sends the data transmitted from the Internet card 51 to the Internet address conversion module 53 through the Internet receiving unit 52, and the Internet data processed by the Internet address conversion module 53 is stored in the storage device ( 44) is output to the connection portion 45.
