Embodiment mono-
This enforcement by reference to the accompanying drawings 1 and Fig. 2 disclose a kind of embodiment of described network appliance power-down detection method and system.Fig. 1 realizes the system schematic that network appliance power-down detects in the present embodiment, Fig. 2 is the flow chart of the detection method of network appliance power-down described in the present embodiment.
As shown in Figure 1, the system that network appliance power-down detects comprises: be arranged on watch-dog 10 in the network equipment, be also arranged on the feature coding device 20 in the network equipment and be arranged on feature coding detector 30 and the optical signal detector 40 in the opposite equip. of the transmission network other end.
Wherein, watch-dog 10, for the supply power voltage state of monitoring network equipment, due in the time there is power down, supply power voltage can pop-off, but have an abnormal process declining suddenly, and watch-dog 10 catches the abnormal decline of power down moment supply power voltage, and then command characteristics encoder 20 generates power-down features coding.The power supply of the network equipment is for example DC power supply, and watch-dog 10 detects in real time to the voltage of DC power supply, and the decline of the moment noting abnormalities reports to feature coding device 20 immediately.
Wherein, in the time monitoring abnormal decline of supply power voltage appearance of the network equipment, the network equipment cuts off the transmission of regular traffic data, and described power-down features coding employing full tunnel mode is sent to transmission network immediately, does not need power supply to keep the regular hour.Power-down features coding is not limited to certain byte, and has occupied whole passage, and even the frame swynchronization code of SDH is all tied up, and has 100% uniqueness.
Whether optical signal detector 40, occur that for detected transmission light path receive power-down features coding at feature coding detector 30 after light signal disappears, and if so, triggers feature coding detector 30 to network management unit reporting ent equipment generation power down fault.
The method flow diagram detecting with reference to the network appliance power-down shown in Fig. 2:
As shown in step 201～step 203, be arranged on the situation of the real-time supervision supply power voltage of watch-dog 10 in the network equipment, detect and whether occur abnormal decline, if find that there is abnormal decline, command characteristics encoder 20 generates power-down features coding according to setting in advance, this power-down features coding distinguishes with regular traffic data, as coded system or frequency difference; If declined without abnormal, show that supply power voltage is stablized or in normal fluctuation range, continue to monitor.
In the time generating power-down features coding, according to shown in step 204, the transmission that the network equipment cuts off regular traffic data immediately adopts full tunnel mode to send to transmission network immediately described power-down features coding, in other words, feature coding is not limited to certain byte, and has occupied whole passage, like this under equal conditions, every 125 microseconds can send 155520000 bits, realize high-speed transfer power fail warning.
As shown in step 205, the feature coding detector 30 that is arranged in the opposite equip. of the transmission network other end is encoded according to coded system or frequency search power-down features from the data of receiving, then judge whether to find power-down features coding according to step 206, if, perform step 207, further whether occur that by optical signal detector detected transmission light path light signal disappears; If not, return to step 205 and continue search power-down features coding.
As shown in step 207, whether opposite equip. detected transmission light path occurs that light signal disappears, if so, and as step 208, to network management unit reporting ent equipment generation power down fault; If not, as step 209, to network management unit reporting ent equipment generation power supply transient fault.
That is to say, before detecting that power-down features is coded in, after light signal disappears in, must thoroughly damage for electric power system power-off or the network equipment power supply of the network equipment of far-end; If power-down features coding detected, but do not detect that light signal disappears, show that power-down features coding may be the flase drop being caused by power failure.
Preferably, optical signal detector 40 also for: after feature coding detector 30 receives power-down features coding, whether detected transmission light path occurs that light signal disappears, if not, trigger feature coding detector 30 to network management unit reporting ent equipment generation power supply transient fault.In other words, if fail to detect that light signal disappears after power-down features coding being detected, the excessive fluctuation of network equipment power supply that can judge far-end has triggered the generation of power-down features coding and has sent, this fluctuation is sporadic, if there is this sporadic fluctuation in continuous several times, the power-down features coding that causes repeatedly flase drop, belongs to power supply transient fault, and is not that electric power system power-off or power supply thoroughly damage.So, described system and method is not only the detection of the network equipment power-off of far-end, but expands to the power monitoring of far-end network equipment, can screen out the alarm of electric power system power-off, the thorough breakage alarming of power supply and power supply transient fault.
In network appliance power-down detection method and system described in the present embodiment, watch-dog monitors the direct voltage of network equipment power supply, while finding lower than setting threshold, cut off immediately regular traffic transfer of data, and command characteristics encoder generates power-down features coding, described feature coding device adopts full tunnel mode to send to transmission network immediately described power-down features coding, feature coding detector searches in transmission network opposite equip. also receives described power-down features coding, then optical signal detector detects the disappearance whether light signal has occurred again, if the disappearance of light signal detected again after power-down features coding being detected, can determine that this light disappearance of signal is caused by far-end network device powers down, belong to the power down fault that electric power system power-off or artificial closing device cause, not transmission cable fault or device power supply (DPS) fault, if the disappearance of light signal do not detected after power-down features coding being detected, thereby certain has occurred the power supply that can determine equipment causes the voltage drop of moment extremely.Can screen out accurately, reliably like this failure cause of power fail warning, be convenient to take in time treatment measures.
Described network appliance power-down detection method and system, not needing does not have special requirement to the power supply of the network equipment, and watch-dog is directly connected with power supply, and the output of detection is directly connected to feature coding device, in the time that supply voltage is abnormal, power-down features coding can send immediately.
In addition, when generating after power-down features coding, cut off regular traffic transmission, all passage is all used for sending power-down features coding, and theoretic transmission speed can be faster, does not need network equipment power supply to keep power supply certain hour.And described power-down features coding is not limited to certain byte, and has occupied whole transmission channel, so have 100% uniqueness.
Preferably, opposite equip. receives the not sensed light signal disappearance immediately afterwards of power-down features coding, but the setting-up time of being separated by is carried out the step whether sensed light signal disappears again, wherein, described setting-up time is determined according to optical module performance in the network equipment, is designed to for example 1 second-2 seconds by computer program.So, can there is the more sufficient time to wait for power cut-off, avoid power supply transient fault to cause that power-down features coding is mistaken for power down fault.
In fact, because power-down features coding sends in equipment voltage change process, therefore in the time receiving, possibly cannot accurately differentiate business datum or power-down features coding, the error code causing for fear of this accidentalia, cause the false judgment to power down fault, the present invention also provides a kind of preferred execution mode, specifically in following examples, describes.
