AI management module includes:
Analysis of experiments
The first part that AI management is realized is analysis of experiments.
Big data database is established, using MYSQL database, related data is tested in typing.Data source mainly has following
Three parts:
(1) historical data is tested；
(2) core operation step data are tested；
(3) test result；
By analysis of experiments, the case where can testing with fast reaction, the quick check test of testing crew is allowed whether to succeed.
Multi-person synergy
Multi-person synergy management, generally at least 4 people；Towards testing crew, division, the peace of role and task are carried out to testing crew
Row simulates actual experimental situation, can distribute the testing crew of different numbers to complete corresponding test operation.
The implementation method of AI management module
It based on C/C++ development language, by graph traversal algorithm, realizes that result calculates, by optimal result, obtains role, stream
Journey, the optimum allocation result of task.
Graph traversal is the important operation of one kind of figure.So-called traversal refers to the access of the information to nodes all in figure,
Successively node each in figure access once and is only accessed primary.Due to from some given node, have it is multiple can be with
The next node (figure is not linear data structure) gone to, so in the case where sequence calculates (i.e. non-parallel computation), only
The access to certain nodes can be postponed --- it saves in some way to visit again later.Common way is to use
Stack (LIFO) or queue (FIFO).Due to scheming it is a kind of data structure for self quoting (i.e. recursive definition) in itself, very certainly
Or more precisely recursive fashion can also be so used, with corecursion, to realize the preservation of delay node.At this moment it (adopts
The case where with recurrence) these nodes are saved in call stack.
Realization process:
(1) testing crew number is a people, corresponds to the figure (a > 0) of a start node；
(2) experiment process is decomposed into b step, corresponding weight is arranged in each step, be denoted as b (1), b (2), b (3) ...,
b(n)；
(3) the depth-first traversal algorithm for passing through figure, begins stepping through respectively from a node, calculates corresponding weight, as a result distinguish
It is denoted as w (1), w (2), w (3) .., w (a)；
(4) graph traversal result is analyzed, weighting weight sum is compared, and chooses corresponding test optimal dividing and distribution knot
Fruit.
Data security module
Data security module uses asymmetric encryption mode, guarantees the safety of system data.
The introduction of asymmetrical encryption technology
Encryption Algorithm is divided into symmetric encipherment algorithm and rivest, shamir, adelman, it is asymmetric in mainly apply rivest, shamir, adelman.
Asymmetric encryption, which refers to, is integrated into the encryption skill in asymmetric to meet security requirement and ownership verifying demand
Art.Asymmetric encryption uses two asymmetrical passwords usually in encryption and decryption processes, is referred to as public key and private key.It is non-
There are two features to tool for symmetric key: first is that with after one of key (public key or private key) encryption information, only another is right
The key answered can just be unlocked.Second is that public key can be open to other people, private key then maintains secrecy, other people can not be extrapolated by the public key
Corresponding private key.
Asymmetric encryption introduction
In systems, the application scenarios of encryption mainly include information encryption, digital signature and login authentication etc..
It is implemented as follows:
(1) information encryption is public key encryption, private key decryption, it is ensured that the safety of information；
(2) digital signature is private key encryption public key decryptions, it is ensured that the belongingness of digital signature；
(3) login authentication private key encryption, public key decryptions.
Realization principle introduction:
(1) information encryption scene is mainly to be encrypted using the public key of recipient (being denoted as B) to information by information transmitter (being denoted as A)
After be then forwarded to B, B decrypts information using the private key of oneself.
(2) digital signature scene is then to use A using B, B is sent to after oneself private key encryption information by sender A
Public key to information decryption, to can ensure that information is sent by A.
(3) login authentication scene is then by client using being sent to server, Hou Zhejie after private key encryption log-on message
The public key decryptions of the client are used after receipts and authenticate log-on message
The present invention optimizes traditional simulation training structure and frame, introduces artificial intelligence management mode, and be directed to multi-person synergy task
Intelligent management and analysis of experiments, step by step give student training, and can count the Grasping level of student.It can allow electrical equipment
L-G simulation test is more bonded reality, really achievees the purpose that analogue simulation, improves training efficiency.
