The invention relates to a serial communication method and device, computer equipment and a storage medium. The method comprises: enabling a receiving end to obtain current filtering data output by afilter; when a preset state in the current filtering data is detected, obtaining valid data after the preset state in the current filtering data; after the effective data is received, waiting for a receiving delay time length, and acquiring next filtering data output by the filter by a receiving end; and taking the next filtering data as the current filtering data, and when a preset state in the current filtering data is detected, obtaining effective data after the preset state in the current filtering data. Data is filtered through a filter, the receiving end only needs to capture the currentfiltering data output by the filter, when the preset state in the current filtering data is detected, effective data in the current filtering data can be obtained, the data receiving duration of thereceiving end is prolonged, namely, delayed receiving is achieved, and therefore the accuracy of the data received by the receiving end can be guaranteed.
