摘要
在飞行控制系统中,对系统安全性、可靠性、可用性的要求不断提高,系统的容错控制能力也在不断的发展。ARINC659是一种具有较高吞吐量、严格的故障隔离、数据传输确定特性的数据总线。描述了ARINC659背板数据总线协议规范中使用的两种容错机制,并实现了容错机制,使用verilog语言设计实现并给出了相应的仿真结果,能够有效的实现对一路故障以及部分两路故障的屏蔽保证系统的可靠性。
In flight control system, the demand for the system security, reliability, usability increased gradually, the fault-tolerant control ability also has get development gradually. ARINC659 is the data bus with the characteristic of the high throughput,rigid fault isolation and data determination in transmit. The paper describes and implements the two kinds of fault- tolerant mechanisms in the criterion of the ARINC659 backboard data bus protocol. Design with the verilog lauguage and present the emulation result, can efficiently achieve to shield the single fault and part of two different fault and ensure the stability of the system.
