Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Embodiment 1
The embodiment of the invention provides a kind of line card fault locating method, this method starts module by increase failure diagnosis on the ply-yarn drill that is provided with normal startup module, can be when ply-yarn drill can not normally start registration, switch to failure diagnosis and start module, ply-yarn drill is carried out complete detection, generate start detection information, and with the start detection information uploading master board that generates, master board in memory, can to ply-yarn drill be carried out fault location according to described start detection information with the start detection information stores.As shown in Figure 1, the concrete steps of the embodiment of the invention are as follows:
Step 101: when ply-yarn drill can not normally start registration, switch to failure diagnosis by original normal startup module and start module.
Concrete switching mode can be manual type or automated manner: manual type is to force to switch by the capable mode of artificial input command; Automatically mode is that handover triggering condition is set, and specifically comprises the number of starts, ply-yarn drill start-up time, master board judgement etc., when reaching handover triggering condition, finishes the switching that starts module to failure diagnosis automatically.For example, when ply-yarn drill starts registration 3 times when unsuccessful, promptly automatically switch to failure diagnosis and start module.
Step 102: failure diagnosis starts module ply-yarn drill is carried out complete detection, generates start detection information, and will send master board on the start detection information that generate.
Wherein, ply-yarn drill is carried out complete detection, promptly detect all hardware resource of ply-yarn drill, after detecting fault, if not the Primary Component fault, be that ply-yarn drill can continue to start, upper layer software (applications) does not respond reset request, and promptly system does not reset to ply-yarn drill, directly carry out the detection of the next item down, ply-yarn drill resets after the ply-yarn drill detection finishes, avoids detecting fault, can't find that the problem of the fault point that the back may exist occurs; If the Primary Component that detects in the ply-yarn drill breaks down, then ply-yarn drill possibly can't start registration, and detection this moment will finish and will directly generate start detection information by sending master board on the normal passage.
Ply-yarn drill can generate start detection information in the complete detection process, and send master board with the start detection information cache that generates on behind the ply-yarn drill internal memory, and wherein this start detection information comprises the content of detection and the result of detection.With the concrete mode of sending master board on the described start detection information can be to send in real time in detecting, and also can be to send on the whole after having detected, and sending on real-time in the detection is a kind of scheme of optimum, helps in real time to fault location and fault eliminating.Break down for ply-yarn drill, and this fault causes that ply-yarn drill can not register, when for example the key chip in the ply-yarn drill breaks down, preferably send master board by normal passage in real time start detection information.When ply-yarn drill breaks down, and this fault can't influence ply-yarn drill and start registration, when for example on the ply-yarn drill break down in the non-key space of non-key chip or key chip, can directly carry out the detection of the next item down, after the ply-yarn drill complete detection finishes, send master board with whole start detection information on the whole by normal passage again.
It is different startup modules with normal startup module that failure diagnosis starts module, because when ply-yarn drill breaks down, just switch to failure diagnosis startup module and carry out complete detection by normal startup module, can't increase ply-yarn drill normal start-up time so carry out complete detection, can meet the need of market like this.
In order to reach better effect, when switching to failure diagnosis startup module, the master board meeting is carried out insulation blocking to ply-yarn drill, and be about to the tape jam ply-yarn drill and be masked as state not on the throne, and with other ply-yarn drill working properly of this state notifying.At this moment, other ply-yarn drill and tape jam ply-yarn drill can not communicate, thereby avoid the tape jam ply-yarn drill to influence ply-yarn drill working properly.
Step 103: master board receives start detection information, and master board or other special-purpose fault locators are carried out fault location according to start detection information to ply-yarn drill, and then can realize by Telnet ply-yarn drill being carried out fault location and fault eliminating.
After master board receives start detection information, can be in the memory of self with the start detection information stores.At this moment, can carry out fault location to ply-yarn drill according to start detection information.At present, carry out fault location and mainly contain following three kinds of methods:
First, under the software realization situation that difficulty is low or CPU usage is low, in master board, automatically start detection information and normal start detection information are compared, comparing result is directly alarmed or is stored in the daily record, and judge the fault of location ply-yarn drill, thereby realize that ply-yarn drill fault location and fault get rid of according to comparing result.
So-called normal start detection information is meant that entering failure diagnosis startup module by the normal ply-yarn drill of order enforcement carries out the formed detection information of complete detection, this detection information is stored in the memory of master board in advance, so that compare, thereby realize fault location with start detection information.
Second, when software is realized under the high situation of difficulty height or CPU usage, to compare with normal start detection information from the start detection information that master board is obtained by the Fault analytical device, and judge the fault of locating ply-yarn drill, thereby realization fault location and fault are got rid of according to comparing result.
The 3rd, directly carry out fault location and fault eliminating referring to the start detection information of storing the memory in the master board from controlling platform.
In order to reach best effect, master board can also be designated ply-yarn drill normally after receiving start detection information, promptly allow ply-yarn drill to carry out the tape jam registration, it is capable then ply-yarn drill to be carried out related command, carries out fault location more meticulously, difference software fault and hardware fault.Under the insulation blocking state, the ply-yarn drill of other operate as normal and the fault wire of getting along well stick into row communication, and promptly for normal ply-yarn drill, this ply-yarn drill is the fault ply-yarn drill.
