Design and Implementation of a Generalized Safety Fault Diagnosis System for China Space Station Scientific Experimental Rack
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe conclusions do not confirm the scientific novelty of the article, which nullifies the results of reliable operation of programs and sensors during operation. There is no scientific novelty of the article in the abstract or in the conclusion. How the specific planned control was carried out, how the service life was carried out or laid down, did not require intervention or how they intervened was not taken into account. The article must be given a specific fact or process that made it possible to specify or write an article. Without this data, the article will look like a report to the management.

Reviewer 2 Report
Comments and Suggestions for AuthorsThis paper focuses on designing a universal fault diagnosis system to ensure the stable operation of SER. The study has important implications, however, this manuscript seems to be a product description, seriously lacking theoretical support and scientific verification. There are several important issues that need to be addressed in this paper.
1. The abstract of the manuscript needs major revision, and I do not see the scientific problems, theoretical problems, research status and the author's research basis of the study
2．In the first or second part, you should show the content and focus of the research, preferably with clear diagrams. There are many inaccuracies and unclear contents in the article, such as the second part.
3. Is the font format in the first paragraph of Part 3 clearly different from other paragraphs in order to highlight some special meaning? Additionally, the numbering of the content in part 3.2 is repeated.
4. Figure 2 is not clear enough, for example, I can not find the FPGA in Figure 2 where.
5. Units of time on line 157 cannot be written this way.
6. The software and algorithm design part, namely the fifth and sixth parts, just like the function introduction, does not reflect the advanced nature of the algorithm and simple software design ideas.
7. The object of fault diagnosis in Part 6 is not clearly stated, and the logic is not clear.
8. Some abbreviations introduced in the paper have not been given their full names, and there is a lack of standardized definitions.
9. The most critical point is that this manuscript has not been verified by experiments, and I am not sure whether the content designed in the manuscript is feasible or can meet its performance requirements.
10. The references are too few and very old, and I do not think that they can help this manuscript to achieve a satisfactory result.

GENERAL QUESTIONS
(i) Title of the manuscript could be further amended to reflect the novelty of the research conducted. As of now, it looks good but could be further improved to reflect the novelty.
(ii) An abstract is a shortened version of the work conducted and should contain all information necessary for the reader to determine. It would be great if the author could improve by adding those elements:
(1) what the objectives of the study were;
(2) how the study was done;
(3) what results were obtained;
(4) and the significance of the results.
(5) the application where the research could be implemented.
(iii) References as mentioned should focus more references between 2019 to 2024.
