Described embedded processing mainboard comprises:
The data input module is in order to obtain subscriber data; And
Processing unit is in order to formation that realizes interface data and the work of controlling the inner or outside module of embedded processing mainboard.
Described embedded processing mainboard also comprises the network communication module that is connected with described processing unit, in order to described interface data is synchronously passed to other display terminals.
Described network communication module comprises one or more in blueteeth network communication module, ethernet communication module, the 3G mobile network communication module.
Described locating module is the matrix-scanning net that is made of gather infrared receiver tube around the substrate and infrared emission tube.
Described embedded processing mainboard adopts fpga chip.
The utility model comes the required software and hardware of integrated realization the utility model function by embed an embedded processing mainboard on substrate, and then replacement is complicated and move inconvenient computer, makes the utility model than conditional electronic blank following advantage be arranged: use is flexible, cost reduces, popularity rate is better.The utility model is provided with the synchronous upload function of network communication module to realize uploading while writing by the embedded processing mainboard, make that using the utility model to say is not subjected to the restriction in space class hour, concrete communication modes comprises blueteeth network communication, ethernet communication, 3G mobile network communication; Therefore, the utility model is overturned the pattern of traditional enterprise's meeting and corporate training and academic exchange, realizes the strange land synchronous AC.
Description of drawings
Fig. 1 is the structural representation of conditional electronic blank;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model embedded electronic blank comprises a substrate, locating module, embedded processing mainboard and projector, and locating module is connected with the embedded processing mainboard respectively with projector, and locating module and embedded processing mainboard are installed on the substrate.Wherein, locating module is the matrix-scanning net that is made of gather infrared receiver tube around the substrate and infrared emission tube; The embedded processing mainboard comprises processing unit and the network communication module, the data input module that are connected with processing unit, is provided with various in order to assist to finish the software that the utility model function needs in the processing unit; The network communication module comprises blueteeth network communication module, ethernet communication module, 3G mobile network communication module, can certainly include only one of them or two; The embedded processing mainboard is to connect projector by its high-resolution true color VGA video output interface that is provided with.
The principle of work of the utility model embedded electronic blank: the hardware (for example USB flash disk) that will have data is connected to the data input module, and processing unit reads data and data is presented on the substrate by projector; When the user need annotate or refreshes or during operation such as conversion data, can on substrate, not contact by writing implement (opaque lip pencil thing) and write operation (also it doesn't matter to touch substrate), locating module feeds back to processing unit in real time with the location parameter of writing implement then, processing unit is judged the operating position parameter, the data that shows with needs in time is presented at interface data on the substrate by projector in conjunction with forming interface data again then; Simultaneously, processing unit is also passed to other display terminals with interface data by the network communication module, the synchronous upload function that realization is uploaded while writing, being convenient to other users watches and downloads at any time, thereby make utilization of the present utility model not be subjected to the restriction in space, for enterprise's meeting training, meaning still is great for education for this.
The utility model provides two power supply interfaces; The one, the primary power interface: the DC power supply interface, be the DC pup J-Horner, be used for external Miniature Power Unit, can be the embedded processing mainboard 5V/3A is provided electric current; The 2nd, the standby power supply interface: the USB power supply interface for USB Slave socket (USB device is divided into HOST (main equipment) and SLAVE (slave unit)), by external USB double end cable, can provide 5V/1A electric current for the embedded processing mainboard.
