介绍了一个无人直升机监控平台的设计和实现,重点是高精度定时器的实现和使用。以802.11b 协议实现无线网络实现连接,以vc++ 6.0 作为开发平台。通过多线程的引入,在接受图形用户界面的操作的同时,利用高精度定时器接受实时飞行数据。经过实际使用,系统达到设计要求。 关键词: 无人直升机;监控平台;高精度定时器;多线程 Abstract: This paper presents the design and implementation of Monit Platform for an autonomous helicopter. The platform was realized the wireless network connect with 802.11b protocol and developed by vc++ 6.0 With multithreading, the platform can receive real-time fly data with high-resolution timer while respond the user’s operation in GUI.
