摘要:

运用WIFI无线通信技术、ARM Cortex A8处理器嵌入式系统、TCP/IP协议以及无线局域网监控等技术设计并制作了一个Android平台的多用户无线投影控制系统。通过WIFI无线通信技术建立用户端与无线投影网关的无线通信,解决了数据连线对投影仪使用时的限制,极大地方便了有线投影仪用户使用无线投影功能。本系统通过无线局域网实现多用户、多平台的无线投影,采用一主多从的方式进行切换,适用于PC机和Android手持移动设备。系统经测试,达到使用要求。本文还详细描述了无线投影网关设计和无线投影管理软件设计。

Abstract:

Using the WIFI wireless communication technology, the ARM Cortex A8 embedded system, TCP/IP protocol and WLAN monitoring technology, we design a control system of multiuser wireless projection system on Android. Establishing wireless communication between the client and the wireless projector gateway by WIFI wireless communication technology can solve the constraints of data line, and it is greatly convenient for cable projector users to use wireless projection function. The proposed system with one leader and multifollowers can implement multiuser and multiplatform wireless projection by WLAN, and it is suitable for PCs and Android mobile devices. In addition, we also describe in detail the wireless projection gateway and the design of wireless projection management software. Test results show that the system meets operating requirements.
