Multi-channel data processing method, device, electronic device and storage medium

Abstract

The invention discloses a multi-channel data processing method, device, electronic equipment and storage medium. Including: sending the inconsistent data independently generated by the corresponding functional modules of each channel in the combined failsafe architecture to each other channel in the combined failsafe architecture; sending the inconsistent data independently generated by the corresponding functional modules of each channel and receiving Inconsistent data independently generated by the corresponding functional modules of each other channel in the combined fail-safe architecture, according to the preset data processing method, each channel in the combined fail-safe architecture is processed independently, and each channel is independent The processed new data; the subsequent input data of each channel is determined according to the new data independently processed by each channel. It can improve the identification ability and applicability of the combined fault safety technology to the abnormality of the channel, play the role of the combined fault safety technology, improve the safety, and ensure the independence of the channel.

Description

Technical field [0001] The invention involves the field of rail transit technology, and specially involves a multi -channel data processing method, device, electronic equipment and storage media. Background technique [0002] In order to ensure high safety requirements in the field of rail transit and avoid dangerous side output in the system, combined fault safety technology is usually used. That is, a key function is performed by at least two independent channels. Only when a passage is more than a certain number of channels, it is allowed to provide external output permits. In the combined fault safety architecture, the functions of each independent channel are the same, and there are two types of data of the following two types: (1) As long as the channels are running normally, the value of the data generated by each channel is consistent; the vast majority of the channels involved in the channel involved Data are all types; (2) Even if all channels are running normally, diff...

Problems solved by technology

[0003] In the combined fail-safe architecture, since each channel is independent, when it comes to "multi-channel inconsistent data", different channels will produce different values, and the subsequent two channels use different data for calculation, which may cause two The output of the channels is inconsistent, which affects the operation of the system; in order to avoid this problem, the current method is that one of the channels obtains such values, and the values ​​are used in this channel and sent to another channel for use. The independence of the channel also invalidates the function of the combined fail-safe architecture. The trusted data is only generated by a single channel, which leads to common cause failure. Common cause failure refers to the failure of multiple channels caused by a single reason, resulting in system failure.
