Problems solved by technology

[0003] In the four-redundancy fault-tolerant computer, the traditional majority voting fault-tolerant strategy will produce uncertainty under the 2:2 voting result, which destroys the strong real-time performance of the strong real-time and high-reliability control system, and affects the key timeliness of tasks

Embodiment 1

[0028] Such as figure 1 As shown, a fault-tolerant strategy based on experience learning is implemented based on a four-redundancy fault-tolerant computer. According to experience learning, the failure frequency of each channel is recorded to evaluate the credibility of each channel. The fault-tolerant strategy includes the following steps:

[0029] Four channels in a four-redundancy fault-tolerant computer collect discrete, analog, and digital signals, and perform majority voting on the input signal. The record count of the channel corresponding to the collected fault in the credibility list is increased by 1, after multiple collections and votes , Perform credibility evaluation based on experience learning for each signal channel;

[0030] The four-channel processing unit in the four-redundancy fault-tolerant computer processes the input signal, and the processing result is cross-transmitted through the internal communication channel, and the processing result is majority voted. T...

Embodiment 2

[0038] The present invention will be described in further detail below.

[0039] Such as figure 1 As shown, the typical composition of a four-redundancy fault-tolerant computer includes: 4 channels with the same input function, processing function, and output function. The software and hardware of the 4 channels can be similar or dissimilar. The traditional majority voting fault-tolerant strategy can realize fault identification and fault isolation in most cases, but under the four-redundancy architecture, the uncertainty generated by the 2:2 voting result destroys the real-time performance of the strong real-time and highly reliable system , The use of fault-tolerant strategies based on experience learning can eliminate this uncertainty based on the credibility evaluation of each channel at each level (input stage, processing stage and output stage). The core part of a fault-tolerant strategy based on experience learning is credibility evaluation. The credibility assessment is ...

Abstract

The invention provides a fault-tolerant method based on empirical learning. The method comprises the following steps: acquiring signals of N channels; voting the signals of the N channels respectivelyto obtain voting results of the N channels; and voting the signals of the N channels according to the voting results of the N channels and the credibility evaluation of the N channels.

Description

Technical field [0001] The invention belongs to the field of strong real-time and high-reliability control system design, and relates to a fault-tolerant strategy for a four-redundancy fault-tolerant computer. Background technique [0002] In order to ensure the reliability of the strong real-time and highly reliable control system, redundant fault-tolerant design methods can be adopted, such as aircraft high-lift control, flight control and engine control, the use of different redundancy fault-tolerant design can improve the reliability of the control system . The key technology of fault-tolerant computer is fault-tolerant strategy. The goal of the fault-tolerant strategy is to identify faults in the system and reconstruct the system, isolate the fault, and prevent the fault from spreading. [0003] In the four-redundancy fault-tolerant computer, the traditional majority voting fault-tolerant strategy will produce uncertainty under the result of 2:2 voting. This uncertainty dest...
