Embodiment Construction
[0017] In order to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Assume that the computer on board a project is a three-mode redundant fault-tolerant computer used in the upper-level control tasks. It adopts a three-mode redundant fault-tolerant design scheme and has three main CPUs. The CPU numbers are 1, 2, 3, namely three Mutual redundant computers, of which there is only one host right, the initial power-on default is the first computer, the 1553B bus working mode of the host is BC mode, the other two computers are MT working mode, BC mode is for bus communication, MT mode is for bus monitoring , If the host is abnormal, the host authority will be transferred to the 2nd unit, at this time the 2nd unit will change to the BC working mode, and the transfer of the main-level authority will be 1> 2> 3> 1. Each computer...
