Description
Technical field
The application relates to fault detection technique, particularly a kind of alarm detection method.
Background technology
For the detection of Real-time Alarm, prior art is all to adopt separately to detect alone mostly, the mode of aggregation process.Concrete processing as shown in Figure 1:
1, each functional module regularly detects dependent failure separately by timing system respectively, by unified interface, is reported to fault management center;
2, by fault management center, to fault is unified, processed, by alarm, represent to user.
There are the following problems for above-mentioned Real-time Alarm detection mode:
1, because check point is many, the detection necessary being of a large amount of Real-time Alarms, and different alarm detection mechanism is different, therefore, cause needing to enable in system a large amount of timer (each check point at least one), and the operation of timer is all the time ceaselessly, have a strong impact on system performance.For the alarm detection of same module, also once there is scheme to attempt merging timer.But because the mechanism of different alarm detection is different: comprise that detection opportunity, sense cycle, Rule of judgment, alarm detection are level and smooth etc., cause a lot of timers to merge, otherwise will increase the complexity of testing mechanism and sacrifice the extensibility of code.
2, for multitasking system, between a plurality of tasks, according to task priority, distribute the timeslice of CPU, priority is high preferentially obtains timeslice, the mean allocation timeslice of level that All factors being equal, preference will be give to.The task function that Processing tasks is realized in the timeslice of distributing.If if higher task processing time of priority ratio is long, will affect the execution of other task.Detection module place task priority is relatively high, when the timer of the detection alarm of this module constantly produces overtime interrupt and processes, take a large amount of CPU, make other task relatively low or All factors being equal, preference will be give to level cannot move or move slower, the operational effect that has affected other function even causes other function normally to move.
Detection for some alarm, due to sense cycle shorter (minimum is that 100ms detects once), and place task priority is relatively high, cause this timer place task to take CPU many, affect the operation of functional module in this task or other task or business module.After system operation, cause other function normally to move, some business cannot be carried out.In serious situation, owing to taking in a large number CPU, system can not be fed dog in time, causes system reset.Because system is to take task as unit operation, for locating this problem, increased difficulty.After problem discover, because alarm detection is also the function that must pay, need to find out in time the mode that substitutes timer, and can not affect the operation of other task.
3, alarm detection is distributed in different modules, and testing mechanism is different, is difficult to unified.Alarm detection point is many, and testing mechanism is different, needs different modules to complete respectively.
Summary of the invention
The application provides a kind of alarm detection method, when can carry out number of different types detection in system, greatly reduces the impact on system performance, improves entire system performance.

Fig. 2 is the particular flow sheet of alarm detection method in the application.
Embodiment
In order to make the application's object, technological means and advantage clearer, below in conjunction with accompanying drawing, the application is described in further details.
Fig. 2 is the particular flow sheet of alarm detection method in the application, for realizing the fault detect to a plurality of check points in system.Wherein, in system, corresponding each trouble shooting point is provided with corresponding fault detection unit, for realizing the fault detect to corresponding failure check point.As shown in Figure 2, the method comprises:
Self-processing task can be realized by an endless loop function, and the cycle that this function is carried out is intercycle.Wherein, intercycle arrange can be rule of thumb with system in fault detect cycle of each fault detection unit set.Conventionally, in system, the fault detect cycle of fault detection unit is the integral multiple of intercycle, like this, can utilize the circulation execution number of times of self-processing task to replace timer to determine duration.
In addition, preferably, priority that can self-processing task is set to lower than other functional modules and business module in system, thus the execution of other tasks in assurance system.
Wherein, fault detect center obtains the sense cycle of each fault detection unit, can be undertaken by pre-configured mode, or also can after system starts, by each fault detection unit, be reported voluntarily.
When fault detect center obtains sense cycle, the dependent failure that can obtain in the lump fault detection unit detects information, such as fault judgment condition, the malfunction of corresponding failure check point obtain interface, fault reports interface and fault type etc.Wherein, in fault judgment condition, can comprise smoothness period etc.
As previously mentioned, intercycle be take as periodic duty in fault detect center, therefore according to the number of times of circular flow, can accurately calculate the duration of experience, add the sense cycle of having determined each fault detection unit by step 202, like this, just do not need to arrange again timer, for the opportunity of determining that each fault detection unit carries out fault detect, but the number of run that utilizes unified fault detect center carries out corresponding duration judgement, thereby which fault detecting point when judgement need carry out fault detect.
When the sense cycle condition of determining a fault detection unit when fault detect center has met, fault detect center notifies corresponding fault detection unit to carry out fault detect.If the malfunction of utilizing step 202 to get each fault detection unit aforementioned is obtained interface, while carrying out fault detect notice here, can directly utilize corresponding malfunction to obtain the corresponding fault detect function of interface interchange (the concrete fault detect that is fault detection unit is processed) and carry out fault detect.Certainly, also can notify by other means fault detection unit, the application is not construed as limiting this.
Fault detection unit can carry out fault detect according to existing mode, and determines fault detect result and report fault detect center.
For avoiding the detection error of primary fault in detecting etc., fault judgment condition can be set, for example smoothness period.Usually, can arrange when continuous several times fault detect result is all diagnosed as fault, judge that corresponding failure check point breaks down; In like manner, after entering malfunction, also can arrange and all be diagnosed as when normal when continuous several times fault detect result, judge that the fault of corresponding failure checkpoint is recovered.
If aforementioned, utilize step 202 to get the malfunction judgment condition of each fault detecting point, receive here after the fault detect result that fault detection unit reports, can judge according to corresponding malfunction judgment condition the current state of corresponding failure check point.Certainly, also can obtain by other means malfunction judgment condition, for judging the current state of fault detecting point, the application is not construed as limiting this.
When determining that according to malfunction judgment condition reversion appears in the current state of certain fault detecting point, for example, from normally becoming fault, or become normally from fault, in fault detect, mind-set user provides corresponding information change.Wherein, when current state is fault, by alarm form, information is offered to user; Current state becomes when normal, the information of recovering to user's prompt alarm.
Wherein, if the fault of utilizing step 202 to get each fault detection unit aforementioned reports interface, when the current state of definite certain fault detecting point is fault here, can utilize fault to report interface that fault status information is reported to fault handling center, by fault handling center, the malfunction of corresponding failure check point be presented to user by alarm form.Certainly, also can to user, carry out by other means the alarm of malfunction, the application is not construed as limiting this.
So far, the method flow in the application finishes.
In said method flow process, when system starts, modules respectively to fault detect center (self-processing task realization) subscribe to the detection of each alarm, subscribe to the time-division and you can well imagine for sense cycle, smoothness period, fault type, fault and report interface, malfunction to obtain interface etc.Fault detect center automatic discrimination in system operational process meets the alarm of testing conditions, then adjusts back corresponding detection function and judges whether fault.After corresponding smoothing processing, adjust back again corresponding alarm sending function alarm is sent to fault management center, by fault management center, complete reporting of alarm.
From above-mentioned, in the application, in order to ensure the normal operation that does not affect other task, fault detect is carried out in self-processing task.Intercycle with self-processing task replaces timer, thereby other tasks can be carried out within the break period of self-processing task.
Meanwhile, it is lower priority that self-processing task priority can also be further set, lower than other functional module and business module.In self-processing task operational process, if when the task of higher priority need to be moved, self-processing task can discharge the disposal right of oneself to other task like this, thereby has guaranteed the operation of other task.By the way, avoid expending too much system resource and moved numerous timers, and as far as possible for other tasks in system provide the more processing time, greatly improved system performance.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
