Specific embodiment
In order to realize detecting power supply adaptor failure, the embodiment of the present invention provides a kind of detection side of power supply adaptor failure
Method, is applied in the PSE that PoE system includes, power supply adaptor is connected on the port of PSE, the end of power supply adaptor and connection
Hold as the PD of POE system, the flow of the method is as shown in figure 1, execution step is as follows：
S11：After receiving the lower electricity notice that port sends, the first current state of port is determined.
When power supply adaptor breaks down, power supply adaptor can be powered off actively, be now connected with power supply adaptor on PSE
Port can send lower electricity notice, PSE can receive the lower electricity notice that port sends, and detection trigger power supply adaptor failure
Flow.
The state of port has three kinds：Normal condition, observation state and punishment state, can be identified by setting flag
The state of port, for example, the corresponding flag of punishment state is false, the corresponding flag of normal condition is true, observes shape
The corresponding flag of state is uncertain.
S12：If the first current state of port is observation state, this lower electricity notice is determined and under last time between electricity notice
Reception time interval whether more than setting time be spaced.
Wherein, setting time interval can be set according to actual conditions, for example, it can be set to being 8 seconds, 9 seconds, 16 seconds
Etc..
S13：If receiving time interval to be spaced more than setting time, the numerical value for observing the factor is added one.
Wherein, the records of values of the observation factor is that reception time interval between lower electricity notice twice exceedes setting time
The read-around ratio at interval.
S14：It is determined that whether the numerical value of the observation factor reaches setting value.
Setting value can be set according to actual needs, for example：It is set as 3 times, 5 times, 7 times, 10 times etc..
S15：If the numerical value for observing the factor reaches setting value, it is determined that power supply adaptor failure, the numerical value of the factor will be observed
Zero setting, and the first current state of port is updated to punishment state, to forbid port output voltage.
Because the records of values for observing the factor is reception time interval between lower electricity notice twice exceedes setting time
The read-around ratio at interval, if the numerical value of the observation factor reaches setting value, it is possible to assert power supply adaptor failure.It is determined that power supply
After adapter fails, when port will be chronically at punishment state, at regular intervals (for example：30 minutes) send power supply adaptor
The prompt message of failure reminds user, asks user to change power supply adaptor in time.This prompt message can include printing
Trap information in syslog and network management etc..
A kind of optional mode, if the numerical value of the observation factor is not up to setting value or receives time interval not less than setting
Time interval, it is determined that power supply adaptor is normal；The numerical value zero setting of the factor will be observed；First current state of port is updated to
Normal condition.
In the program, by the current state of port, the reception time interval and the observation factor of adjacent electricity notice lower twice
Numerical value come determine port connection power supply adaptor whether failure, realize detection power supply adaptor failure, and then guarantee
Enough it is the terminal normal power supply of power supply adaptor connection, it is ensured that power supply adaptor normal work.
Specifically, determining that this lower electricity is noticed and whether is the reception time interval under last time between electricity notice in above-mentioned S12
More than the implementation that setting time is spaced, as shown in Fig. 2 specifically including：
S121：Obtain the electric reception time noticed under last time.
S122：Under the reception time and last time that calculate this lower electricity notice between the reception time of the reception time of electricity notice
Every.
When the difference for receiving the time of electricity notice is as reception under the reception time that this lower electricity can be noticed and last time
Between be spaced.
S123：Time interval will be received to be compared with setting time interval, if receiving time interval is more than setting time
Interval, then perform S124；If receiving time interval to be spaced less than or equal to setting time, S125 is performed.
S124：It is determined that receive time interval being spaced more than setting time.
S125：It is determined that receive time interval being spaced not less than setting time.
S121-S125 determines that this lower electricity notice and the reception time interval under last time between electric notice are there is provided a kind of
The no implementation being spaced more than setting time, can also realize otherwise certainly, repeat no more here.
The embodiment of the present invention provides the detection method of another power supply adaptor failure, as shown in figure 3, as shown in Figure 1
On the basis of also include：
S16：If the first current state of port is punishment state, it is determined that whether port meets punishment state is exited bar
Part；If meeting punishment state exit criteria, the first current state of port is updated to normal condition.
Port into after punishment state, it is necessary to determine whether port exits punishment shape according to punishment state exit criteria
State, punishment state exit criteria can include one of following two conditions：First, port send electricity notice, port by plug,
Enable etc. will send electricity notice, and port once sends electricity notice, then it is assumed that port can exit punishment state；Secondly,
On port it is electric or it is lower electricity state exceed certain hour, be exactly that power supply adaptor has at a time recovered normal work, PSE ends
Cannot may perceive in a short time it is recovered normal, but port is constantly in the state of electricity, if the state of upper electricity
Continue for certain hour (certain hour can be set as 60 seconds), then it is assumed that power supply adaptor is recovered normal, and port is exited
Punishment state, equally, when the state duration of electricity under port exceedes certain hour, is then also considered as power supply adaptor and has recovered just
Often.
S17：If the first current state of port is normal condition, it is determined that power supply adaptor suspected malfunctions, by port
First current state is updated to observation state.
When port is in normal condition, once monitoring port sends the behavior of lower electricity notice, port immediately enters sight
State is examined, and determines power supply adaptor suspected malfunctions, now, port can normally to power supply adaptor output voltage.
A kind of optional implementation method, after the upper electricity notice of port transmission is received, determines the second current shape of port
State；If the second current state of port is punishment state, it is determined that whether port meets punishment state exit criteria；If port is expired
Foot punishment state exit criteria, then be updated to normal condition by the second current state of port.
Based on same inventive concept, the embodiment of the present invention provides a kind of detection means of power supply adaptor failure, applies

Whether the reception time interval under last time between electricity notice is spaced more than setting time；
Module 43 is attached, if being spaced more than setting time for receiving time interval, the numerical value for observing the factor is added one；
Whether the 3rd determining module 44, the numerical value for determining the observation factor reaches setting value；
Update module 45, if reaching setting value for observing the numerical value of the factor, it is determined that power supply adaptor failure, will observe
The numerical value zero setting of the factor, and the first current state of port is updated to punishment state, to forbid port output voltage.
In the program, by the current state of port, the reception time interval and the observation factor of adjacent electricity notice lower twice
Numerical value come determine port connection power supply adaptor whether failure, realize detection power supply adaptor failure, and then guarantee
Enough it is the terminal normal power supply of power supply adaptor connection, it is ensured that power supply adaptor normal work.
