摘　　要：随着无线通信和远程数据采集的应用日益广泛,人们开始认识到在测试监控领域使用无线传输的必要性。本文提出了一种高速无线通信系统设计方案,在硬件电路设计中,分别利用AD849、MAX7410E、AD9200实现放大、滤波、A/D转换等信号调理电路的功能,无线通信模块采用nRF2401芯片,通过STC89C51对整个电路实现基本控制,并经RS232实现与PC的串口通信;在软件设计中,分别列出了发送和接收模块的框图和主程序,最终该系统实现了无线通信的基本功能。With the wireless communication and remote data acquisition are applied widely, people begin to realize that it is necessary to use wireless transmission in testing and monitoring fields. A design scheme of high- speed wireless communication system is put forward in this paper. In the hardware circuits, AD849, MAX7410E and AD9200 are adopted to realize the functions of amplification, filtering, A/D conversion and so on. The wireless communication module adopts nRF2401 chip STC89C51 is used to control whole circuits, and RS232 is used to realize serial communication with PC. In the software, the diagrams and main programs of sending and receiving modules are presented separately. This system realizes the basic functions of the wireless communication finally
