摘　　要：基于S3C2440-Linux嵌入式平台和nRF24L01射频模块,介绍了一种远程数据接收器的设计。该数据接收器利用SQLite3存储nRF24L01射频模块接收来自数据采集节点的数据,用户通过浏览器访问接收器上的BOA服务器进行数据管理。在CGI程序设计中采用Posix消息队列给数据接收器的射频接收单元传递命令,利用多线程的方式对接收到的数据进行处理。这种将传感器采集到的数据通过2.45 GHz无线射频模块发送到数据接收器的方式非常适合用于远程环境监测、旅游管理等场合。A remote data receiver is designed based on S3C2440-Linux embedded platform and nRF24L01 RF module.The data receiver uses SQLite3 to store the data which are received by nRF24L01 RF module from the data acquisition node.Through browser user can access to the BOA server for data management.In CGI program,commands were passed to RF receiving by Posix message queues.Multithreading technology was used to process the received data.The approach of using 2.45 GHz wireless RF module to pass the data which are acquired by sensors to the data receiver is well suited for remote environmental monitoring,tourism management and other occasions.
