The traveling wave tube process digital management system capable of data feedback and problem tracing as claimed in claim 5, characterized in that: The front end uses Html, Javascript, and Jquery, and the back end uses Springboot; for relational data, Oracle11g database is used for storage; for document data, a file server is set up for storage.

7. The traveling wave tube process digital management system capable of data feedback and problem tracing as claimed in claim 1, characterized in that: The specific process of tracing the source of the problem is as follows: S1. Preparation stage: S1-1: Maintain data items and measurement templates in the measurement record management module of the digital management system; S1-2: Bind the measured record template to the corresponding process on the process card maintenance page of the basic data management module; S2, execution phase: S2-1: During the process execution in the production execution management module of the digital management system, select the process involving the actual measurement record and create the corresponding test task; S2-2: The automatic test system executes the test task after receiving it, and stores the test information and data into the result file after the test is completed; S2-3: The data results measured by the automatic test system are sent to the digital management system via the internal network; S2-4: The digital management system analyzes the data and stores, manages or displays the measurement results after analysis; S2-5: During the process of executing a process in the production execution management module of the digital management system, a process involving actual measurement records is selected, and simulation results of the simulation design system are obtained by importing simulation data; S2-6: On the result analysis page of the production execution management module of the digital management system, the page displays the actual test results of the automatic test system and the simulation results of the simulation design system; S2-7: Through the difference analysis function, the system automatically compares the actual test results of the automatic test system with the simulation results of the simulation design system and analyzes the differences; S2-8: Find the possible cause of the problem and process location in the traceability information table based on the difference information; S2-9: Quickly identify production bottlenecks based on problem causes and process positioning to ensure high-quality product delivery.
