Abstract

The application discloses a data writing method and a related device, which relate to the field of distributed control. When the current data writing environment is in a state of being unfavorable for data writing, the data package to be written is split into data segments with the number which is suitable for the current environment and is the target number, and writing is carried out by using smaller data segments, so that the physical influence range and failure cost of single operation are reduced. And when the data writing process of each data segment is sequentially executed according to the arrangement sequence of the target number of data segments, executing a writing cycle of not more than the target number of times for the current data segment in each data writing process, executing a data checking process for the current data segment after the current data segment is written into the flash memory in each writing cycle, and waiting for the target duration after the execution of the writing cycle is completed. By combining the combination of zero integration, one-by-one writing and timely waiting under severe environment, the success rate of the whole writing task is improved.
