Summary of the invention

[0005] The object of the present invention is to provide a distributed integrated power supply management system and method to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solution: a distributed integrated power supply management method, the method comprising: Step S1: monitoring the internal functional modules of the integrated power supply device during power supply operation, sending alarm records generated by alarm information to the upper computer, sorting out the control adjustment data generated by the integrated power supply device according to the corresponding alarm information, and judging and identifying the operation associations between the internal functional modules; Step S2: Evaluate the correlation impact index of each functional module associated with the running job, and sort out the job impact topology network between all functional modules by constructing a one-way impact structure; Step S3: Calculate the influence index of each functional module according to the relationship distribution between each functional module and other functional modules in the job influence topology network; Step S4: Real-time monitoring is performed on the situation where multiple functional modules send alarm information to the host computer concurrently, and the host computer is assisted in making a priority processing decision on the alarm information received concurrently.

[0018] Example: Figure 1-Figure 3 As shown, the present invention provides a technical solution, a distributed integrated power supply management method, the method comprising: Step S1: monitoring the internal functional modules of the integrated power supply device during power supply operation, sending alarm records generated by alarm information to the upper computer, sorting out the control adjustment data generated by the integrated power supply device according to the corresponding alarm information, and judging and identifying the operation associations between the internal functional modules; Wherein, step S1 comprises: Step S1-1: for each functional module integrated in the integrated power supply device, sequentially capture the alarm records of sending alarm information to the upper computer during the power supply operation, and collect all control and adjustment instructions issued by the upper computer according to the alarm information; Step S1-2: Identify the content of each control and adjustment instruction, capture other functional modules involved in the integrated power supply device when executing all control and adjustment instructions, and determine other functional modules as associated modules affected by the corresponding functional module sending the alarm information; Step S1-3: for each associated module extracted from any functional module based on the corresponding alarm record, collect the job running data packet transmitted by any functional module to the upper computer within the unit time before and after the integrated power supply device executes the corresponding control adjustment instruction, obtain the data similarity between the two job running data packets, and set the data similarity as the influence coefficient of each associated module on the any functional module;

Step S2-2: Calculate the association influence index β=N / M+G between a certain functional module A and a certain functional module B, where M is the total number of the associated module set corresponding to the certain functional module A;
