Abstract
The utility model relates to a portable power point (PPT) document play device, which comprises an integration box body and a power supply inverter. An embedded computer circuit board, a liquid crystal display (LCD) touch screen, a universal serial bus (USB) port and a projector video port are arranged in the box body. The volume and the weight of the device are far smaller than those of a universal laptop and a desktop, the device can be directly connected with a projector, and users can complete playing of PPT documents in a USB flash disk on the projector through simple operation of the device.
Description
Technical field
The utility model relates to a kind of portable PPT document playing device that is used for multi-media classroom; This device volume weight is much smaller than general notebook computer and desktop computer; Can directly be connected with projector, the user accomplishes the broadcast of PPT document on projector in the USB flash disk through the simple operations to this device.
Background technology
Existing multi-media classroom teacher utilizes the PPT document roughly to divide two kinds of situation on class: first kind, the fixing PC in classroom is connected with projector.The USB flash disk that the user will be equipped with the PPT file inserts PC, operation PPT file on PC.The distinct disadvantage of this mode is: public PC is owing to use frequently, and its software and hardware damages easily, is difficult to maintenance at once in case break down when using, and has a strong impact on quality on class; Second kind, the user carries notebook computer and is connected with projector, operation PPT file on notebook.The distinct disadvantage of this mode is: carry inconvenience, cost is high.
The utility model content
The purpose of the utility model provides portable PPT document playing device, and it is easy to carry, cost is low, simple to operate, and specificity is strong.
To achieve these goals, the utility model is realized by following technical scheme:
Portable PPT document playing device; Comprise embedded computer plate, liquid crystal touch screen and 220 volts of-5 volts of power supply changeover devices; Wherein embedded computer plate, liquid crystal touch screen are built in integrated box body through the interface line connection, and box body has power interface, USB interface and audio-video interface plate.Power interface is connected with power supply changeover device, and USB interface can be connected with USB flash disk, and video interface can be connected with projector.Described portable PPT document playing device is on the embedded computer plate, and CPU is connected with liquid crystal display through bus, and CPU is connected with touch-screen through the AD input interface, and CPU is connected with the VGA video module through bus, and power module is all component power supply.Described portable PPT document playing device, its operating system software adopts flush type LINUX operating system, and application software can correctly read PPT format file file.Described portable PPT document playing device, its CPU model is SC3C2440.Described portable PPT document playing device, the box body liquid crystal touch screen is fixed on the embedded computer plate, and the front is embedded in the box body front; The embedded computer plate is fixed on box bottom.
The utility model compared with prior art advantage is: main process equipment was safeguarded difficulty when it had solved multi-media classroom broadcast PPT file, carried inconvenience, the problem of inconvenient operation.The portable PPT document playing device that the utility model provides, cost is low, is easy to carry, and is exclusively used in the PPT file and plays, and the hardware and software failure rate is low, and software operation is short and sweet, has very high dirigibility.
