| 摘 要： | 为了满足重要系统的高可靠性要求,特设计了一种双DSP容错控制系统。本系统中两个DSP彼此独立运行,采用硬件判决模块配合DSP软件进行硬件和软件故障诊断,再根据硬件判决模块的结果由仲裁切换模块来进行仲裁,并完成输出切换和报警功能,从而实现容错控制,显著提高了控制系统的可靠性。

| Abstract: | For the high requirements of reliability of important control system,a kind of fault-tolerant control system based on dual-DSP is designed.Among this system,two DSPs run independently each other,hardware circuit module and software which in each DSP cooperate to diagnose errors caused by hardware or software of the control system,according as the result of the hardware circuit module,the switchover will always choose the right DSP output data or give an alarm,so the system has the function of fault-tolerance,and the reliability is greatly improved. |
