Abstract
A method for detecting fault of communication device includes calling on prestored attribute information of sensing object, confirming type of sensing object, confirming fault situation of sensing object and generating a corresponding fault event. The system used for realizing said method is also disclosed.
Description
Technical field
The invention belongs to the plant maintenance field, particularly a kind of communication equipment fault detection system and a kind of communication equipment fault detection method.
Background technology
Because the machine of delaying of communication equipment will cause the paralysis of local or even whole network in the network, therefore, to the availability requirement of communication equipment generally all than higher; Especially for the communication equipment of core in the network, requiring usually provides (99.999%) availability of 59, allows the time of the machine of delaying can not be above 5 minutes in promptly 1 year.
Guarantee so high availability, its prerequisite is to make up perfect fault detection system and fault detection method, if promptly equipment has fault, must be able to detect as early as possible; After detecting fault, must accomplish fault location as early as possible; After navigating to fault, must realization repair fault as early as possible.Only in this way, just might satisfy requirement to the communication equipment availability.
Existing communication equipment fault detection system mainly is made up of perceptive object, awareness tool and fault detection module three parts, as shown in Figure 1, comprise perceptive object 1,2 and 3, the awareness tool 1,2 and 3 that is attached thereto respectively, and parts 1,2 and 3 fault detection module separately.Perceptive object mainly refers to the target that needs are detected, as: temperature, voltage, fan etc.; The effect of awareness tool mainly is a state of gathering these perceptive objects; Fault detection module is mainly coordinated the work of each several part, and the information of comprise the value that reads awareness tool, awareness tool being obtained is carried out necessary processing, control awareness tool etc.Shown in Figure 2, be the fault detection system schematic diagram of a reality.
The flow process of existing communication equipment fault detection method is as follows: fault detection module regularly goes to obtain the value of perceptive object (timing can be decided according to concrete perceptive object) by awareness tool, judge whether fault of perceptive object by the value of the perceptive object that obtains then, if fault just sends alarm event.Wherein, mainly adopt one-level thresholding determining method to judge whether fault of perceptive object, concrete steps are: the value of obtaining perceptive object by awareness tool; The value of the perceptive object that obtains compared with the threshold value that sets in advance (this threshold value can be revised later, thresholding can be divided into Upper threshold and Lower Threshold in addition), if the value of perceptive object, is then thought the status fault of perceptive object greater than Upper threshold or less than Lower Threshold; The person does not just think that the state of perceptive object is normal; Judge the state that detected last time whether with the state consistency of current detection, if inconsistent then thereby the generation state changes incident changes current state, otherwise, do not change current state.
Generally speaking, existing communication equipment fault detection system and fault detection method have following defective:
1,, use different fault detection module to detect at different perceptive objects; Its defective is:
Fault detection capability is scattered on each fault detection module, so need write corresponding fault detection program at different perceptive objects, causes much repeated work, and the cost of developing a whole set of testing software is high;
Write fault detection program at each perceptive object, it is unified that the external interface that each program provided is difficult to, and hindered the transplanting of distinct program and share;
Because the realization of fault detection program is different, has caused the increase of the maintenance cost of later stage software; The compatibility issue that has system simultaneously is unfavorable for the stable of fault detection system;
2, detect the attribute description that needs to solidify perceptive object in the communication equipment in the software; Its defective is:
Owing to detect software at design of communication equipments, therefore in detecting software, solidified the attribute of perceptive object simultaneously, caused the limitation of fault detection system extremely strong, only can the perceptive object of communication equipment at the beginning of the design have been detected, between different communication equipments, can not reuse;
3, adopt one-level thresholding determining method, its defective is:
One-level thresholding determining method can only judge that the state of perceptive object is in fault case or normal state, and can't distinguish in fact the order of severity of fault case (such as fatal/serious/slight etc.), more can't carry out corresponding troubleshooting according to the different orders of severity;
One-level thresholding determining method is a state of judging perceptive object according to the numerical value that obtains immediately, but reason owing to perceptive object, state such as some circuits, just need a measurement period, in a measurement period, meet the requirements if detect the number of times of fault, just think the status fault of circuit; Therefore, traditional one-level thresholding determining method brings erroneous judgement probably.
In sum, existing communication equipment fault detection system and communication equipment detection method are difficult to satisfy the requirement of portability, stability and accuracy, also exist exploitation, maintenance cost height simultaneously, the precision defect of insufficient.

Embodiment
Communication equipment fault detection system provided by the present invention, by to perceptive object unification set up attribute information, type under dividing realizes using unified failure detector that communication equipment is carried out fault detect and handles.
Among the present invention, carry out the perceptive object that attribute information is set up, can be the perceptive object of dividing according to fan, temperature, voltage etc., need the concrete hardware of clear and definite communication equipment to constitute but divide like this, set up even finish attribute information, also be unfavorable for transplanting between the system of fault detection system; Therefore, the perceptive object that is adopted among the present invention, be to monitor as required and the state of the perceptive object that detects is divided, be divided into cycle statistics type perceptive object, statistics type perceptive object, multistage threshold type perceptive object, discrete type perceptive object, watermark type perceptive object and counting type perceptive object continuously.
Wherein, cycle statistics type perceptive object is meant in certain measurement period, and the number of times that the state of perceptive object changes surpasses the number of times of setting, and thinks that then the state of perceptive object really changes.The state of perceptive object changes and comprises two kinds of situations, and a kind of is that the state of perceptive object becomes fault case from normal state, and another kind is to return to normal state from fault case.Give an example: a kind of light signal is arranged, and its measurement period is 1s (second), and sensed light signal is 10 times in measurement period, if in detecting for 10 times, finding has 7 light signals undesired, can think that then light signal breaks down; In like manner, be under the situation of fault case at light signal, if in detecting for 10 times, find to have 6 subnormal, can think that then light signal returns to normal state from fault case.
Continuous statistics type perceptive object, the state that is meant perceptive object are in testing process, and the number of times that recurs change surpasses the number of times of setting, and thinks that then the state of perceptive object changes.For example, a kind of clock phase locked state, if in testing process, it is unusual to be consecutively detected 5 next states, just can think that clock is phase-locked unusual; In like manner, if it is normal to be consecutively detected 6 next states, can think that then the phase-locked recovering state of clock arrives normal state.
Multistage threshold type perceptive object, it is multistage to be meant that thresholding with perceptive object is divided into, and comprises high fatal, high serious, high slight, normal, low fatal, low serious, low slightly state in totally 7.The temperature of veneer for example, its high fatal thresholding are 90 degree, and high serious thresholding is 70 degree, and high slight thresholding is 60 degree, and low slight thresholding is 20 degree, and low serious thresholding is 0 degree, and low fatal thresholding is 0 time 5 degree, normally is between 60～20.
The discrete type perceptive object is meant that the state of perceptive object can be represented with set of number, and the state transition of object is known in the transition representative of perception state.For example the active and standby hardware state of veneer comprises major state and is equipped with state, and the led status of veneer comprises red, green, blue and yellow etc.Although substantially, this state transition is not failure condition, as the reference information of failure condition, often need detect when fault detect yet.
Watermark type perceptive object is meant the perceptive object that needs record maximum and minimum value, for example the CPU occupation rate of veneer.
Counting type perceptive object is meant the perceptive object that needs record accumulative total numerical value and state, for example the transmitting-receiving bag number of the network port.
Obviously, carry out attribute information according to above-mentioned classification unification and set up, then the corresponding type information of each classification can be set up in advance, and does not rely on the hardware formation of concrete communication equipment; After type information is set up and finished, write down the concrete parameter of each awareness tool again.After attribute information is set up, only need the related of in configuration file record actual perceived parts and a certain attribute information, just can in the actual detected process, call this attribute information, handled according to the concrete parameter in the configuration file.
For example, when needs detect CPU, can detect cpu temperature, also can add up the pattern formula and detect the CPU congestion situation according to the cycle according to continuous statistics pattern formula.Wherein, adding up pattern formula, cycle statistics pattern formula continuously is type information, and cpu temperature, CPU be congested then to have other parameter of branch.
Enumerated the said sensed object though it will be appreciated by those skilled in the art that the present invention, only be explanation the present invention's usefulness, promptly the modeling kind of perceptive object is not limited only to above-mentioned six kinds, and can set according to the needs in the actual detected.
