Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
As seen from Figure 1, for physically or multichannel equipment in logic, generally have a plurality of connecting interfaces on whole multichannel connects, each interface is finished communication such as dissimilar electrical characteristics or coupling connection or is connected self needed basic function.In most cases, such design is as the target design object with each interface, not from whole connecting path and entire system the function that should finish unify to consider, therefore just inevitably exist some limitation, comprise fault is difficult to fast location etc.
In order to overcome the limitation of being brought as the target design object with each interface, the present invention from whole connecting path and entire system the function that should finish unify to consider, a kind of Fault Locating Method of multichannel equipment is provided, and the embodiment to this method describes below.
Fig. 2 is the Fault Locating Method implementing procedure schematic diagram of multichannel equipment, as shown in the figure, can comprise the following steps: in the enforcement
In this step,, path can be divided into multistage to terminal from starting point and connect based on the multichannel equipment system architecture.In the practice, the bigger part of the probability of finding to break down is mostly at interface, can consider when therefore dividing sub-linkage section interface as the foundation of dividing, such as directly with interface as sub-linkage section etc.
For ease of describing, the path that will break down among the embodiment is called first path, and the normal path of on-state index is called alternate path;
When determining alternate path, can pass through the path detection algorithm,, search out a regular path as alternate path as fixed data transmitting-receiving loopback or system channel shock Response Analysis etc., this path is preferably selected idle path in concrete the enforcement, also can adopt certain redundancy backup path.
In this step, the one or more son of first path connected to change be connected to alternate path, thereby the son of the path of winning being connected connected by the corresponding son of alternate path replaces.From the Origin And Destination of multichannel equipment, a few partons of first path connect with other sons of alternate path and are connected splicing, have just formed a new complete path, just adopt the path of these new formation as test access in the enforcement.
The on-state index test of this step can detect by the path detection algorithm, as fixed data transmitting-receiving loopback or system channel shock Response Analysis etc.
In this step, can determine in step 203 whether sub-linkage section belongs to first path, in step 206, can determine the on-state index of each sub-linkage section in each test access.
Because alternate path is normal, therefore the sub-linkage section in the alternate path all is normal, and the sub-linkage section in first path may have normal and abnormal situation simultaneously in test access, learn easily, as long as it is once normal in a certain test access, just can determine that this sub-linkage section is normal, otherwise it is impossible normal; And if a sub-linkage section all is undesired in all possible test access, it must contain fault undoubtedly, thereby causes all paths that comprise it all undesired.Based on this, can determine:
When the sub-linkage section that belongs to first path, the on-state index in each test access is when undesired, and then this sub-linkage section contains fault;
When the sub-linkage section that belongs to first path, the on-state index in each test access has one at least just often, and then this sub-linkage section does not contain fault.
For ease of understanding, the execution mode of two kinds of extreme fault locations is proposed below, a kind of method of exhaustion, a kind of traversal method that is called of being called.Under the method for exhaustion, during enforcement exhaustive go out all sub-linkage sections at first path and alternate path form test accesss may, then whether each sub-linkage section is contained fault and judges; Under the traversal method, judge one by one with the sub-linkage section of first path whether this sub-linkage section contains fault successively.Yi Zhi, whether contain the failure judgment criterion in conjunction with the antithetical phrase linkage section, under the exhaustive scheme, once just can find the sub-linkage section that there is fault in all, and under the traversal scheme, then locate the sub-linkage section that contains fault, if first path is normal after recovering, then can stop fault location, can save the formation and the test of a part of test access, save the time.Yi Zhi can form the scheme that multiple location contains the sub-linkage section of fault in conjunction with two kinds of schemes, and is exhaustive as getting the possible test access of a part earlier, carries out the exhaustive scheme such as reduce by half of next part successively.
Under the method for exhaustion, its concrete enforcement can be:
By being connected and opening circuit between each sub-linkage section in first path and the alternate path, form the test access that all can be used to detect;
Detect the on-state index of each test access;
Determine each sub-linkage section on-state index in each test access respectively according to the on-state index testing result;
Whether belong to first path and the on-state index in each test access determines whether contain fault in each sub-linkage section according to sub-linkage section,
Contain all faults of location the sub-linkage section of fault from all.
Under the traversal method, its concrete enforcement can be:
By being connected and opening circuit between each sub-linkage section in first path and the alternate path, be formed for the test access that detects successively;
Detect the on-state index that this time forms test access;
Determine each sub-linkage section on-state index in each test access respectively according to the on-state index testing result;
Whether belong to the sub-linkage section that described first path and the on-state index in this time test access determine to contain fault successively according to sub-linkage section, to orienting all faults.
The embodiment of the invention also provides a kind of fault locator of multichannel equipment, describes below in conjunction with the embodiment of this device of accompanying drawing.
