自动气象站数据采集器一般基于单片机或PC／104总线控制器设计，具有与PC兼容性好、功耗低、体积紧凑等特点，然而如何设计出功能强大，网络传输功能强的自动气象站数据采集器，满足现代气象检测的要求，是一个值得研究的课题。文中基于ARM微处理器和Linux操作系统平台，借助前端无线传感器网络的数据输入，利用嵌入式Qt的开发优势并设计数据通信格式，完成无线气象数据通信系统的设计，实现了数据的可靠...[详细]
利用CAN232B转换器组建CAN控制网络

一、引言由于RS232通讯距离短（根据EAT/TAI-232标准，仅为15米），而且，只能进行点到点通讯，不能直接组多点通讯网络。为了延长RS232的通讯距离，并将RS232节点组成通讯网络，目前广泛使用RS232/RS485信号转换器。但是，由于RS485通讯本身的局限性，在实际应用中存在许多不足：总线效率低、系统的实时性差、通讯的可靠性低、网络工程调试复杂、传输距离不理想...[详细]
