The invention discloses a multi-controller redundant system, which adopts three sets of identical automatic driving controllers to work simultaneously regardless of primary and secondary, takes two groups of data with closest results as a correct judgment principle in each link, selects one of the two groups of data with the closest results to be jointly executed by people, and performs next-step operation according to the selected two groups of data. And in the final result, one of two closest groups of data is still selected as a common decision. During working, three sets of same automatic driving controllers work at the same time, the principle that minority obeys majority is always adopted for three groups of data, the rule penetrates through each link, errors are continuously eliminated, and the data in each step are unified on a correct road. The method has the beneficial effects that three sets of same automatic driving controllers are used for working at the same time, the difficulty of judging which part the fault comes when the automatic driving system breaks down is solved, the redundancy reliability is improved, and the method is also suitable for various devices such as airplanes and steamships.
一种多控制器的冗余系统,采用三套相同的自动驾驶控制器不分主次且同时工作,在每一个环节都以结果最接近的两组数据作为正确的判断原则,选择最接近的两组数据之一供大家共同执行,并据此进行下一步的运算,而最后结果依然选取最接近的两组数据之一作为大家共同的决策。工作时,三套相同的自动驾驶控制器同时工作,对待三组数据总是采取少数服从多数的原则,而这一法则贯穿于每一环节,不断排除错误,把每一步数据都统一在正确的道路上。本发明的有益效果是,利用三套相同的自动驾驶控制器同时工作,解决了自动驾驶系统出现故障时,判断故障来自哪一方的困难,提高了冗余的可靠性,而且也适合于飞机、轮船等多种装备。
