摘要
针对远程数据传输系统中不同通信接口标准间信号灵活切换的需要,采用AT89C51作为主控制器,结合MAX232、MAX485接口驱动芯片,设计了一款智能多通道远程数据传输系统接口转换器。给出了硬件设计电路及相应通信软件的设计方法,同时采用Visual Basic6.0设计了简单友好的主机程序人机界面,最后对该转换器进行了各通道的数据传输测试。实际应用表明,利用该转换器可以灵活地在各种接口间传输数据信息。
This paper introduces an intelligent interface converter applied for multi-channel remote data transmission system. The AT89C51 ,combining with MAX232 and MAX485, was used for main controller in converter. The design methods include hardware circuit and the corresponding communication software. Using Visual Basic 6.0, it designs a simple and friendly human-computer interface. Finally, this paper processes the detail tests concerned with data transmission between different channels. It shows that the converter can flexi-bility to transfer data information between the various interfaces.
