针对无线多点高清视频监控的需要，提出了一种基于TITMS320DM355DSP芯片的无线高清摄像头的设计与实现，重点介绍了它的组网设计架构和软硬件实现流程图。该摄像头采用无线方式传输视频数据，监控摄像头移动灵活易于部署，而且功耗较小。“,”In this paper, using high density polyethylene and wood fiber as the main raw materials, produces 4 types of wood-plastic composites with different contents of wood flour through hot molding process. The effect of wood fiber content on the corrosion resistance of wood-plastic composites was studied by testing mass loss rate, the bending strength and surface morphology before and after corrosion. The results of the research indicates that WPC would be corrupted in the condition of Gloeophyllum trabeum; the higher content of wood fiber, the more severely corrupted of WPC; Gloeophyllum trabeum could easily corrupt the wood fiber from WPC, but not plastic.
