Description
(一)技术领域(1) Technical field
本实用新型涉及一种自播放式投影仪，尤其涉及一种不依赖于PC机就可以播放各种文件的投影仪。The utility model relates to a self-playing projector, in particular to a projector capable of playing various files without relying on a PC.
(二)背景技术(2) Background technology
目前投影仪应用非常广泛，但其自身只是一个投影设备，自身没有存储、处理功能，更不能访问互联网，其应用主要依赖于PC机。这就限制了投影仪应用的灵活性，以及可移动性，并且因为要依赖于外部存储、处理设备，相应浪费了能源和设备的损耗。At present, the projector is widely used, but it is only a projection device. It has no storage and processing functions, let alone access to the Internet. Its application mainly depends on the PC. This limits the flexibility and mobility of projector applications, and because it depends on external storage and processing equipment, energy and equipment losses are correspondingly wasted.
(三)发明内容(3) Contents of the invention
本实用新型针对现有技术投影仪必须依赖于PC机的不足，公开了一种不依赖于PC机的自播放式投影仪，其可以从可移动存储设备上读取各种文件，进而对文件进行播放。The utility model aims at the deficiency that projectors in the prior art must rely on PCs, and discloses a self-playing projector that does not depend on PCs, which can read various files from removable storage devices, and then to play.
本实用新型采用以下技术方案：The utility model adopts the following technical solutions:
本实用新型自播放式投影仪，包括投影仪模块，还包括作为所述投影仪模块上位机的嵌入式计算机系统，以及与该嵌入式计算机系统连接用于接收外部存储设备数据的USB接口；还包括与该嵌入式计算机系统连接的触摸屏和液晶显示器。The self-playing projector of the utility model includes a projector module, and also includes an embedded computer system as an upper computer of the projector module, and a USB interface connected with the embedded computer system for receiving external storage device data; It includes a touch screen and a liquid crystal display connected with the embedded computer system.
上述自播放式投影仪，还包括与所述嵌入式计算机连接的语音录放模块、视频录制模块和网卡。The self-playing projector above also includes a voice recording and playback module, a video recording module and a network card connected to the embedded computer.
上述自播放式投影仪，所述嵌入式计算机系统为基于ARM为CPU的嵌入式计算机系统。For the above-mentioned self-playing projector, the embedded computer system is an embedded computer system based on ARM as CPU.
本实用新型自播放式投影仪包括有用于接收外部存储设备数据的USB接口，用于接收外部数据，然后送入嵌入式计算机系统进行处理，经处理后的数据通过投影机模块进行进行投影。另外所集成的液晶屏作为人机界面，触摸屏则作为人机交互接口界面，从而实现不借助PC机而实现对外部数据进行投影显示。采用触摸屏作为人机交互接口界面具有体积小，外形美观的特点。由于USB接口是目前应用非常广泛的一种串行接口，支持包括U盘、可移动硬盘、可移动光驱等外部存储设备，也支持网络接口，应用非常广泛。本实用新型自播放式投影仪还集成有语音录放模块和视频录制模块，用于数据采集，延伸了其使用范围。嵌入式计算机系统采用基于ARM11的嵌入式计算机系统，其能耗低，性能好。The self-playing projector of the utility model includes a USB interface for receiving data from an external storage device, and is used to receive the external data, and then send the data to an embedded computer system for processing, and the processed data is projected through the projector module. In addition, the integrated LCD screen is used as the man-machine interface, and the touch screen is used as the man-machine interaction interface interface, so as to realize the projection display of external data without using a PC. Using the touch screen as the human-computer interaction interface has the characteristics of small size and beautiful appearance. Because the USB interface is a serial interface that is widely used at present, it supports external storage devices such as U disks, removable hard disks, and removable optical drives, and also supports network interfaces, so it is widely used. The self-playing projector of the utility model is also integrated with a voice recording and playback module and a video recording module, which are used for data collection and extend its application range. The embedded computer system adopts the embedded computer system based on ARM11, which has low energy consumption and good performance.
