Summary of the Invention

[0005] The purpose 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 purpose, the present invention provides the following technical solution: A distributed integrated power supply management method, the method includes:

[0007] Step S1: Monitor the alarm records generated by each functional module inside the integrated power supply device when sending alarm information to the host computer during power supply operations, sort out the control adjustment data generated by the integrated power supply device according to the corresponding alarm information, and judge and identify the operation associations existing between each internal functional module;

[0008] Step S2: Respectively evaluate the associated influence index of the functional modules with operation associations, and by constructing a one-way influence structure, sort out the operation influence topology network existing between all functional modules;

[0009] Step S3: Calculate the influence degree index of each functional module according to the relationship distribution presented between each functional module and other functional modules in the operation impact topology network.

[0010] Step S4: Monitor in real time the situation where multiple functional modules concurrently send alarm messages to the host computer, and assist the host computer in making a priority processing decision on the concurrently received alarm messages.

[0011] Preferably, step S1 includes:

[0012] Step S1-1: For each functional module integrated inside the integrated power supply device, sequentially capture the alarm records that send alarm messages to the host computer during the power supply operation, and at the same time collect all the control and adjustment instructions issued by the host computer according to the alarm messages.

[0013] Step S1-2: Identify the content of each control and adjustment instruction, capture the other functional modules involved when the integrated power supply device executes all the control and adjustment instructions, and determine all the other functional modules as the associated modules affected by the functional module that sends the corresponding alarm message.

[0014] Step S1-3: For each associated module extracted from any functional module based on the corresponding alarm record, collect the operation data packets transmitted by any functional module to the host computer within a unit time before and after the integrated power supply device executes the corresponding control and adjustment instruction, obtain the data similarity between the two operation data packets, and set the data similarity as the influence coefficient of each associated module on any functional module; the smaller the influence coefficient corresponding to the associated module, it indicates that the data similarity between the operation data packets transmitted by the associated module to the host computer before and after the integrated power supply device executes the corresponding control and adjustment instruction is smaller, that is, the data deviation degree between the operation data packets is larger, which also means that based on the current alarm message, the degree of intervention and adjustment of the operation state of the associated module needs to be greater, and it also reflects that the operation job association degree between the current functional module that sends the alarm message and the associated module is higher.

[0015] Step S1-4: For each functional module, respectively sort all the associated modules extracted based on the corresponding each alarm record from large to small according to the influence coefficient, and generate several associated module sets corresponding to each functional module; the larger the sequence value, the smaller the corresponding data similarity, and the higher the operation job association degree between the current functional module that sends the alarm message and the associated module; based on an alarm message sent by a functional module, an associated module set can be extracted, that is to say, whenever a functional module sends an alarm message to the host computer, the recognition and judgment of the associated module for the functional module are completed once.

[0016] Preferably, step S2 includes:

[0020] Preferably, step S3 includes:

[0021] Step S3-1: In the operation influence topology network, traverse the functional modules at both ends of the indication arrow in any one-way influence structure, and sequentially use each functional module as the starting point, along the direction of the indication arrow, accumulate the number Q of functional modules directly and indirectly connected to each functional module through the indication arrow, and the average association influence index β of all the one-way influence structures involved in the Q functional modules e ;

[0022] Step S3-2: Default the initial priority weight coefficient η = 1 for each functional module; when it is captured that a certain functional module is both the starting end of the indication arrow in a certain one-way influence structure P1 and the arrow pointing end of the indication arrow in a certain one-way influence structure P2, if a closed-loop route including the certain one-way influence structure P1 and the certain one-way influence structure P2 can be extracted from the operation influence topology network with the certain functional module as the starting point, add one to the priority weight coefficient η of the certain functional module; the closed-loop route refers to the route starting from a certain functional module, along the direction of the arrow of the indication arrow in a certain one-way influence structure P1, and finally along the arrow of the indication arrow in a certain one-way influence structure P2 pointing to the certain functional module;

[0023] Step S3-3: Extract the final priority weight coefficient η' accumulated for each functional module; calculate the influence degree index δ = Q×β e ×η'.

[0024] Preferably, step S4 includes: when it is detected in real time that F functional modules concurrently send alarm information to the host computer, that is, F functional modules simultaneously send alarm information to the host computer, prompting the host computer to sort the F functional modules in descending order according to the corresponding influence degree index, and processing the alarm information sent by the F functional modules with reference to the sorting order.

[0025] To better implement the above method, an integrated power supply management system based on distribution is also proposed. The system includes: an alarm information management module, a topology network construction management module, an influence degree index evaluation module, and an alarm priority management module;

[0026] The alarm information management module is used to monitor the alarm records generated when each functional module inside the integrated power supply device sends alarm information to the host computer during the power supply operation, sort out the control adjustment data generated by the integrated power supply device according to the corresponding alarm information, and judge and identify the operation associations existing between the internal functional modules;

[0043] Among them, step S1 includes:

[0044] Step S1-1: For each functional module integrated within the integrated power supply device, sequentially capture the alarm records that send alarm messages to the host computer during the power supply operation, and simultaneously collect all control and adjustment instructions issued by the host computer based on the alarm messages.

[0045] Step S1-2: Identify the content of each control and adjustment instruction, capture the other functional modules involved when the integrated power supply device executes all control and adjustment instructions, and determine all other functional modules as associated modules affected by the functional module that sends the corresponding alarm message.

[0046] Step S1-3: For each associated module extracted from any functional module based on the corresponding alarm record, collect the operation data packets transmitted by any functional module to the host computer within a unit time before and after the integrated power supply device executes the corresponding control and adjustment instruction, obtain the data similarity between the two operation data packets, and set the data similarity as the influence coefficient of each associated module on any functional module.

[0047] Step S1-4: For each functional module, respectively sort all the associated modules extracted based on each corresponding alarm record in descending order of the influence coefficient, and generate several associated module sets corresponding to each functional module.

[0048] Step S2: Respectively evaluate the associated influence index for the functional modules with associated running operations, and by constructing a one-way influence structure, sort out the operation influence topology network existing among all functional modules.

[0049] Among them, Step S2 includes:

[0050] Step S2-1: Traverse all the associated module sets of each functional module; if among all the associated module sets corresponding to a certain functional module A, there are a total of N associated module sets that contain a certain functional module B, sequentially capture the sequence values of the arrangement of a certain functional module B in the N associated module sets, and obtain the average sequence value G.

Therefore, the priority weight coefficient η of the function module D needs to be cumulatively added by one;

[0058] Step S3-3: extract the final priority weight coefficient η' accumulated for each functional module; calculate the influence index δ=Q×β of each functional module e ×η'.
