舰载分布式系统总线局网HJ-90具有很高的数据传输速率,有较强的冗余容错能力,可入网节点数多达256个,它对于海军舰载指挥控制系统及其它一些实时控制系统的连网都具有很强的实用性。本文作者首先对该总线局网的硬件实现方法作了简要介绍,然后,作者着重就接口板调试中遇到的问题,对该总线局网的调试方法作了详细介绍。 HJ-90 has a high data transfer rate, strong redundancy and fault tolerance, as many as 256 nodes can be connected to the network. It is very useful for naval carrier-based command and control systems and other real-time control The system’s network are highly practical. The author firstly introduces the hardware implementation of the bus station network briefly. Then, the author focuses on the problems encountered in the debug of the interface board, and introduces the debugging method of the bus station network in detail.
