Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
According to Fig. 1, Fig. 2 and Fig. 3, the present invention includes the diagnostic result display device, also has a failure diagnosis engine, this failure diagnosis engine comprises a script interpreter and a corresponding fault location module at the fault diagnosis model description script, through the TCL interpreter, after adopting Tool Command Language TCL to carry out diagnostic operation, the fault location module is transported to diagnostic result display device and diagnostic result database of record with diagnostic result; The fault diagnosis model of communication system fault diagnosis system is the fault location tree of tree; The fault location tree is a kind of general good fault location model, it realizes fault location by the deterministic process of a series of YES/NO, simulate the logic of artificial fault judgement, each deterministic process is called an action, after a series of action judgement, finally provide the conclusion of diagnosis, the structure of fault location tree is exactly a binary tree structure in fact, each non-leaf node is an action, and leaf is the conclusion of diagnosis.
As shown in Figure 2, the present invention adopts this explainable script to describe fault diagnosis model, the internal judgment logic of fault diagnosis model is after fault location, carry out diagnostic operation, this diagnostic operation utilizes the data in system command and the network management data storehouse, adopts general script, as Tool Command Language TCL, come the defining operation order, behind the diagnostic operation, operating result is transported to external equipment or database.
Be a fault location tree at certain product " PPE port traffic fault " as shown in Figure 3, diamond is called the decision frame among the figure, represents an action, just with the diagnostic operation that decides next step trend; Rectangle frame is represented a conclusion of diagnosis or is handled suggestion, is referred to as processing block, is exactly a final diagnostic result.
A fault location tree can be made up of a plurality of subtrees, each subtree all is a binary tree structure as shown in Figure 3, relation between each subtree walks abreast, that is to say and all will travel through each subtree in the Fault Diagnosis process, even the subtree of front has obtained a diagnostic result, so in use has stronger flexibility.
The failure diagnosis structure as shown in Figure 1, fault location tree structure described above is described with a kind of script of explainable failure diagnosis descriptive language; Each diagnostic operation determines that just the action in the frame is described with Tool Command Language TCL script.
Introduce the grammer of failure diagnosis descriptive language below:
Fault location of each script describing tree is made up of 3 sections, respectively with＜PARAM 〉,＜NODE 〉,＜TREE〉start.＜PARAM〉section is statement to action parameter;＜NODE〉section is the statement to each action node Dec and processing node Proc;＜TREE〉section then defined set membership between the node, forms tree.Some action also needs just can finish from outside input number order parameter the execution of order, therefore need parameter information in the script, obtaining of these parameter values may directly be obtained from the end user by user interface there, also may be the return value of the action carried out of front.
Be the script example of certain product RLOS alarm below:
<PARAM>
Opt_num (" opposite end tabula rasa number ");
Cros_num (" opposite end cross board number ");
Clk_num (" opposite end clock board number ");
<NODE>
TOP_FAULT (" RLOS alarm ");
Dec1 (" opposite end tabula rasa TF alarm ", " check warn tf %% ", opt_num);
Dec2 (" opposite end tabula rasa OPM_FAIL alarm ", " check warn opmfail%% ", opt_num);
Proc1 (" is ") normally;
Proc2 (" opposite end tabula rasa fault ");
Dec3 (" opposite end is luminous normal ", " check light %% ", opt_num);
Dec4 (" our station is unglazed ", " check receive ");
Dec5 (" the our station luminous power is too little ", " check recv-low ");
Proc3 (" optical fiber is disconnected ");
Proc4 (" our station optical module or fibre loss are big ");
Dec6 (" the opposite end cross board is not on the throne ", " check board%% ", cros_num);
Dec7 (" opposite end clock board BD_STATUS alarm ", " check warn bd_status%% ", clk_num);
Dec8 (" the local terminal loopback does not have the LOS alarm ", " check warn los locallp ");
Proc5 (" opposite end cross board or clock board fault ");
Proc6 (" the opposite end cross board is not on the throne ");
Proc7 (" the opposite end clock board is not on the throne ");
Proc8 (" other reasons ");
<TREE>
TOP_FAULT＝Dec1+Dec3+Dec6；
Dec1＝Dec2+Proc2；
Dec2＝Proc1+Proc2；
Dec3＝Proc2+Dec4；
Dec4＝Dec5+Proc3；
Dec5＝Proc1+Proc4；
Dec6＝Dec7+Proc6；
Dec7＝Dec8+Proc7；
Dec8＝Proc5+Proc8；
Above-mentioned script has 2 kinds of statements: statement statement and assignment statement, the statement statement is used for declaring a parameter or tree node, parameter and tree node identifier are self-defining, as parameter opt_num and node Dec1, Dec2 etc., the naming rule of identifier is with beginning of letter, heel letter, numeral or underscore.
Concerning the parameter statement, adopt the character string that round parentheses bracket in the above-mentioned script that parameter is described, effect is just in order to tell the user as prompting the descriptor of this parameter when allowing the terminal use that parameter value is provided, can certainly parameter not done statement, thereby this parameter does not have information, and this way mainly is used in by action and returns rather than the user provides the situation of parameter value.
The statement statement of tree node is also similar, and in round parentheses at first is description character string to this node, and action node Dec back is also had action command character string and possible parameter, just has only node to describe character string to processing node Proc.Continuous 2 percentage signs " %% " in the command string are the format characters, represent that this position replaces with an input parameter; Equally, an action command can return several output parameters, as long as catch up with the output parameter sequence in the back of input parameter sequence, and will add " ﹠amp before the identifier of each output parameter; " number.As: DecisionA (" the Serdes loopback is given out a contract for a project test normally ", " test channel serdeslp%% ", port_num ， ﹠amp; Packet_num) port_num is exactly an input parameter in, the actual value that when ordering the %% in the command string is replaced with port_num that sends, and this action is returned a parameter to packet_num, may use in the action afterwards of this parameter, so just not need warning terminal user that the value of packet_num parameter is provided." TOP_FAULT " in the node statement is the keyword of language, represents which phenomenon of the failure this fault location tree is used to locate.
＜TREE〉assignment statement in the section represented the association of node, and the assignment statement of TOP_FAULT has been represented the root node of each subtree, and other assignment statement "=" number left side is a father node, and this father node can only be the action node, can not be processing node; "=",, number the right was NO node+YES node, therefore＜TREE〉section illustrated the logic association of tree node.The assignment statement right side also can have only a child node in addition, no matter that is to say the judged result of father node is YES or NO, all go to this child node, this is just not judge in order to obtain other required parameters of action in order to adapt to some action, as obtain some states of system by an action, supply other action commands as input parameter, and do not need manually to obtain these states.
Script can be with note, and note begins to finish to one's own profession with # number.
After starting diagnosis, each action of diagnostic engine is exactly the TCL script of carrying out an action in fact, check at first whether this action needs parameter, if parameter had been composed value, then directly use this value, otherwise just point out the user to import, carry out corresponding operation then and receive return results, the result is judged output parameter is arranged then also will extract preservation if specify in the action; Through a series of action and logic determines, finally obtain diagnostic result.Relation between each subtree walks abreast, and that is to say that each subtree all will travel through in the diagnostic procedure, even the subtree of front has obtained a diagnostic result.
