摘要
为解决ARCNET网络因节点数多、系统庞大而易产生网络故障,降低整个系统可靠性的问题,设计了具有网络自诊断的通信系统。首先,在ARCNET初始化时进行本节点内部运行诊断,确保本节点自身硬件处于正常状态;其次,采用网络诊断的方法检查在初始状态及通信过程中整个ARCNET网络的状态;最后,利用软硬件结合方式解决网络故障并给予用户相应的提示。同时,提出了延迟接收的方法,解决了ARCNET网络中前一帧数据破坏后一帧数据导致数据丢失问题,提高了ARCNET网络的通信效率,增加了整个通信系统的可靠性和稳定性。
In order to solve the problem that the ARCNET network has a large number of nodes,the system is large and easy to generate network faults and reduce the reliability of the whole system,a communication system with network self-di- agnosis is designed.First of all,ARCNET initialization during the diagnosis of internal operation,to ensure that the node＇s own hardware in a normal state.Secondly,the method of network diagnosis is adopted to check the state of the whole ARCNET network in the initial state and communication process.Finally,the combination of hardware and software to solve network problems and give the user the appropriate prompt.At the same time,the method of delay reception is proposed,which solves the problem of data loss caused by that the previous frame data corrupts the next frame of datain ARCNET network, improves the communication efficiency of ARCNET network.
