摘　　要：针对传统的有线视频传输方式限制小型地面机器人行动范围和灵活性的问题,设计了一套数字无线视频传输系统。介绍了系统结构,着重描述了硬件组成,简要介绍了软件功能和流程。发射子系统采用了双核DSP处理器BF561和2.4 GHz高速无线收发芯片nRF24L01+,实现了小型化和低功耗。系统采用了H.264视频编解码标准,实现了PAL制式D1级别的图像分辨力,最后经实验测试,系统能在200 m范围内可靠传输实时视频。In order to solve the problem that traditional cable video transmission restricts the moving range and flexibility of small ground robot ,a set of digital wireless video transmission system is designed. The architecture of the system is introduced ,and hardware is described in detail while function and flow path of software in brief. The sending sub-system which is small in scale and low in power consumption is consisted of dual-core DSP chip BF561 and 2.4 GHz high-speed wireless transceiver chip nRF24L01＋. The whole system could handle picture resolution of PAL D1 level with H. 264 video coding/decoding standard. A test is conducted which indicates capability of reliable real-time video transmission within range of 200 m.
