Description
Technical field
The invention belongs to technical field of communication equipment, and in particular to a kind of the system stability monitoring and recovery of communication equipment
Method.
Background technique
Prior art, which monitors system stability, to be realized by software watchdog or hardware watchdog, specially
One thread timing dog-feeding, if feeding dog thread abnormal, system reboot if without feeding dog in time occurs.Communication equipment is influenced to stablize
Property the reason of it is very much, wherein include following 3 points: 1.linux order execution state；The readable write state of 2.FLASH memory space；3.
Important thread operating status.
Prior art, which only monitors, feeds this thread of dog, and other function points for influencing equipment stable operation do not have
It monitors, if exception, which occur, in other places also results in equipment fluctuation of service, so existing scheme not can solve
The problem of equipment stable operation.
Summary of the invention
In order to solve technological deficiency existing in the prior art, the invention proposes a kind of system stability of communication equipment
Monitoring and restoration methods.
The invention is realized by the following technical scheme:
A kind of the system stability monitoring and restoration methods of communication equipment, comprising steps of

1.6, whether the implementing result in judgment step 1.3-1.5 fails；If so, executing step 1.8, step is executed if not
Rapid 1.7；
1.7, if ((++ i) >=3), { i=0；, return step 1.2；
1.8, hardware watchdog stops feeding dog, restarts system, terminates process.
(2) the read-write status monitoring of FLASH memory space and recovery, specifically include step:
2.1, FLASH memory space is monitored；
2.2, the second preset time is waited；
2.3, text document is read and write in FLASH memory space, judges to read and write whether result succeeds, if so, return step
2.2, if it is not, entering step 2.4；
2.4, set FLASH is abnormal, and request processing terminates process.
(3) important thread monitoring running state and recovery.
Further, it in the step (1), is executed using linux system instruction ls, ps and free timing, determines life
Implementing result is enabled, and decides whether to call exception handling according to returning the result.
Preferably, first preset time is 30 minutes.
Further, it in the step (2), uses using second preset time as interval, is periodically stored in FLASH
A file is read and write in space, and decides whether to call exception handling according to returning the result.
Preferably, second preset time 12 hours.
Further, further comprise step in the step (3):
3.1 in the beginning location set monitoring request flag position of per thread.
3.2 in the loop body of thread, every once just to add 1 to the counter of the thread into loop body, is monitored thread
The runing time of loop body will be faster than the runing time of monitoring thread loops body.
Just whether 3.3 monitoring threads judge the thread according to the monitoring request flag of each monitored thread and counter
Often operation, to decide whether to call exception handling.
The monitoring method of 3.4 monitoring threads, the counter of the relatively more monitored thread of monitoring thread, if monitored thread
Counter is as last counter values, and it is abnormal that monitoring thread then determines that the thread occurs, if the detection mistake reaches
Exception handling will be called to setting number.
Further, in the step (3), the important thread monitoring running state and recovery further comprise:
A, start, monitor each thread operating status；
B, it waits 60 seconds；
C, thread n=0 is enabled, is monitored since first thread；
D, judge whether that n < m, m are that can monitor total number of threads；If entering step E, return step B if not；
E, judge thread n monitoring mark whether set, if so, enter step F, if it is not, enable n=n+1, return step D；
F, judge whether the thread counter changes；If entering step G；
G, system reboot mark adds 1；
H, judge whether system reboot mark is greater than the set value, if then system reboot；If it is not, enabling n=n+1, step is returned
Rapid D.
Further, in the step (3), each thread for needing to monitor executes step:
A, start, into thread；
B, it is named to thread；
C, set thread monitors flag bit；
D, every to add 1 into thread counter of loop body into thread loops body；
E, other business in processing cycle body, return step D.
